Description

[Technical field]

[0001] The present invention relates to a drawn steel pipe and a manufacturing apparatus and method for the same, and more particularly to a metal hoop coiled pipe assembly useful for continuous processing such as the production of drawn steel pipes, and a tube shrinking apparatus for supplying the assembly. [Background technology]

[0002] There is a background art relating to a drawn steel pipe and its manufacturing method in which a metal hoop-shaped coiled tube material is reduced in stages multiple times to make a thin tube in the stepwise tube reduction process of a cylindrical tube. The background art is that a coil material or hoop material is a rolled metal material that has a hoop shape with a hole in the middle and is suitable for mass production. Here, there is a manufacturing method that uses a relatively thin tube as a material as a metal hoop-shaped coiled tube material in the process of further processing a relatively thin tube into a further thin tube by drawing, etc. There is a manufacturing method that uses a relatively thin tube as a material as a metal hoop-shaped coiled tube material in the process of further processing a relatively thin tube into a further thin tube by drawing, etc. There was no prior background art relating to "Solving the technical problems and creating the action and effect of <continuous> supply of workpieces of non-parallel processing machines (serial processing machines or single processing machines)" in a J-PlatPat search before April 19, 2024. In response to these background techniques, the present invention <newly> focuses on a drawn steel pipe and a manufacturing method thereof with higher productivity in a manufacturing process that uses this relatively thin tube as a "metal hoop-shaped coiled tube material" material. Regarding the metal hoop-shaped coiled tube material and the manufacturing method thereof, which are produced by drawing and shrinking a metal hoop-shaped coiled tube material in multiple stages to produce a thin tube in the stepwise drawing and shrinking process of a cylindrical tube, the techniques described in the background techniques have a problem in that they do not provide any of the functions, actions, or effects corresponding to the means requirements of the present invention described below and the requirements of the present invention. There is a use of metal hoop-shaped coiled tube material, which is effective for mass production, for sheet-like materials called fixed-length materials. Metal hoop-shaped coiled tube materials are characterized by a hoop shape, i.e., a toroidal (annular) shape, and a shape with a hole in the middle.

[0003] As background art, in the prior art, regarding the continuous drawing processing of steel pipes and its "setup change", there was no technology in the J-PlatPat search that provides the function and effect of assembling and continuously supplying metal hoop-shaped coiled pipe material as the technical requirements of "steel pipe", "tube shrinking", "drawing", and "continuous processing" in the continuous drawing processing of steel pipes, as of April 19, 2024. In the continuous drawing processing of steel pipes, there was no prior art means that "solves the technical problem and creates the function and effect of <assembly and continuous> supply of metal hoop-shaped coiled pipe material workpieces to non-parallel processing machines (serial processing machines or single processing machines) without stopping the operation of the processing machines such as tube shrinking, without stopping the supply of the next metal hoop-shaped coiled pipe material workpiece after the end of a series of metal hoop-shaped coiled pipe material workpiece supply, and without stopping the processing of the processing machines such as tube shrinking" as a metal hoop-shaped coiled pipe material, as of April 19, 2024.

[0004] In "all manufacturing except drawing processing", when "steel pipe" is "shrunk" and "change of setup", after the series of metal hoop coil tube workpiece supply is completed, there was no background technology or prior art to switch to the next new metal hoop coil tube workpiece supply without stopping the processing machine such as shrinking. In order to start the next new metal hoop coil tube supply, the only way was to stop the processing machine such as shrinking, and to process the front of the next new metal hoop coil tube material by external setup and manual work by skilled workers so that it could withstand the continuous processing of the processing machine such as shrinking, and then to start the continuous processing of the next new metal hoop coil tube material. This invention opens the way and provides a means for continuous processing without stopping the shrinking processing machine or stopping the processing machine such as shrinking. There was no technology that simultaneously meets the technical requirements and concepts of "assembling" and "joining" metal hoop coil tube materials in a J-PlatPat search before April 30, 2024. In addition, regarding the technical requirements and concepts of "shrinking" a "steel pipe", deforming it in some way, and "assembling" and "joining" a metal hoop-shaped coiled tubing material, a J-PlatPat search found 47 patent documents that may be related to the technical requirements and concepts of "shrinking" a "steel pipe", deforming it in some way, and "joining" it as of April 30, 2024 or earlier. However, when checking the contents of all 47 patent documents, although they include the joining of steel pipes, resin, and columns, there is no technology related to the assembly and joining of a series of metal hoop-shaped coiled tubing materials. In both all technical areas except "change of setup" of continuous drawing processing of steel pipes and the technical area of ​​"change of setup" of continuous drawing processing of steel pipes, there was no technology in the J-PlatPat search as of April 30, 2024 that simultaneously meets the technical requirements and concepts of "shrinking" a "steel pipe" and "assembling, joining, supplying equipment and supply method to the tube shrinking processing machine" of the workpiece during "change of setup". Among these, we extracted the top four patent documents whose means and constituent features are at least somewhat likely to be closest to the present invention.

[0005] Patent Document 1 discloses a joint structure for a diaphragm wall that does not require the trouble of changing the setup and can further reduce the pull-out resistance of the partition plate by adding a simple structure. In Patent Document 1, a hollow box joint 10 is arranged on the upper side of the joint part between a leading panel 14 and a trailing panel 22 that constitutes the diaphragm wall, and the upper sides of the joint parts of the leading and trailing panels 14, 22 are rigidly connected together via the box joint 10, and the lower sides of the joint parts are connected to each other by cutting joints. The box joint 10 is provided with a partition plate 16 that is erected at a setback position from the opening of the joint surface to close the opening surface, a seal material 18 that is integrally formed on the lower part of the tip surface of the partition plate 16 and contacts the end of the groove hole 14a of the leading panel 14, and crushed stone 20 that is filled in a setback space formed between the top surface of the seal material 18, the upper part of the tip surface of the partition plate 16, and the end of the groove hole 14a. Patent Document 1 has a problem in that it does not achieve any of the means and requirements of the present invention as a manufacturing device and manufacturing method for shrinking a metal hoop-shaped coiled tube material multiple times to make a thin tube in a stepwise tube shrinking process of a cylindrical tube, and does not achieve any of the actions and effects corresponding to the requirements of the present invention. Furthermore, Patent Document 1 does not have the configuration, actions, or effects of the means for continuously supplying a hoop-shaped coiled material as in the present invention.

[0006] Furthermore, Patent Document 2 discloses "an apparatus for supplying wire to a production machine, the apparatus comprising a support, first and second drawing dies mounted on the support, and first and second capstans mounted on the support for rotation about first and second axes, the first and second capstans operable to draw first and second wires through the first and second dies, each capstan having an inlet end for receiving the respective wires from the respective dies and an outlet end through which the respective wires are supplied to the production machine, the first and second wires from the first and second capstans extending along first and second paths, respectively, the first and second axes being disposed on the support such that the first and second paths converge towards each other as the paths proceed downstream from the capstans towards the production machine." Patent Document 2 has a problem in that it does not meet the requirements of the present invention as a manufacturing device and manufacturing method for reducing a metal hoop-shaped coiled tube material multiple times in a stepwise tube reduction process to make a thin tube, and does not achieve any of the actions and effects corresponding to the requirements of the present invention. Furthermore, Patent Document 2 does not have the configuration, actions, or effects of the means for continuously supplying a hoop-shaped coiled material as in the present invention.

[0007] Furthermore, Patent Document 2 states that "the workpiece is stopped," whereas in the present invention, "the workpiece is not stopped." Patent Document 2 states that "the workpiece is cut," whereas in the present invention, "the workpiece is not cut." Patent Document 2 states that "the technical issues of supplying workpieces to parallel processing machines and the creation of functions and effects" whereas in the present invention, "the technical issues of supplying workpieces to non-parallel processing machines (serial processing machines or stand-alone processing machines) and the creation of functions and effects" are different in other respects. <The basis for the description of Patent Document 2 showing the difference between Patent Document 2 and the present invention> "Furthermore, assume that a second line has been set up with wire 15°" and is in a standby state with its front end extending through guide tube 25' and just protruding into guide path 41' of Y-shaped guide 40 (see Figure 4 of Patent Document 2)." During operation of the first line, "the capstan 21 pulls wire 15 from coil 15A through wire drawing die 17, where it is wound onto the capstan. Wire 15 then extends from capstan 21 between feed roll 250, past cutter 36, through guide tube 35, and along guide paths 41 and 42 of Y-shaped guide 40 to feed roll 11." As the feed roll rotates, it pulls cutter 15 from capstan 21 and supplies the wire to production machine 10. Next, "assume that the wire 15 of the coil 15A of the first line is nearing a worn state. When the rear end of the wire 15 is detected visually or automatically, the feed roll 11 of the production machine 10 is stopped. When the feed roll 11 stops, the compensating arm 23 stops the capstan 21. This stop preferably occurs when the rear end of the wire 15 is positioned closely between the wire drawing die 17 and the unwinder 16 (see FIG. 3 of Patent Document 2). "As soon as the wire 15 is stopped, it is cut by the cutter 36 at a point between the guide tube 35 and the feed roll 25. The wire is cut by the feed roll 25 (see FIG. 3 of the '2 patent), and the clutch 45 of the upper feed roll 25 holds the wire against the reverse pull by the feed rolls away from the cutter. "When the wire 15 is cut, the rotation of the feed rolls 11 is resumed and they feed the remaining length of the wire 115 to the production machine (see FIG. 3 of the '2 patent), and after this wire is consumed" the feed roll 25' of the second line is rotated instantly to advance the front end portion of the wire 15° into the guide path 42 of the Y-shaped guide 40 and then to the feed roll 11. When the feed roll 11 takes control of the wire 15', the operation proceeds as described above, but the production machine 10 is replenished by the second line. "During the time that the second line is operating, a new coil 15A-2 of wire 15-2 (Fig. 5 of Patent Document 2) is loaded into the uncoiler 16 and its front end is extended to a close position (see Fig. 5 of Patent Document 2). The front end of wire 15-2 and the rear end of wire 15 are then welded together to place the coil 15A-2 in the system.While the welding is taking place, the front end of the vA 15 can be manually or automatically chamfered to prepare the end for feeding to the production machine IO. After the welding and chamfering are completed, the feed roll 25 is briefly driven to advance the front end of the vA 115 into the guide path 41 of the vA guide 40 in a waiting position to await consumption of the vA 115 from the second line. The cycle then repeats as described above, but the second line is stopped and the first line is started when the second line is consumed. Although the waiting position has been described in detail as the wire protruding into the Y-shaped guide, the waiting position can be immediately downstream of the feed rolls 25 and 25 or can be anywhere between these feed rolls and the Y-shaped guide. " Patent Document 2 also does not disclose the configuration, operation, or effect of a supplying device and method for continuously supplying hoop-shaped coil material to an assembly, joining, and tube shrinking machine as in the present invention.

[0008] In Patent Document 3, in order to manufacture a short pipe having a tapered surface for chamfering for press-fitting from a hoop material, the hoop material 1A is set in an uncoiler 1, and the coil is passed through a leveler to remove stress. A tapered surface corresponding to the chamfering for press-fitting is plastically deformed 2a1 on either the upper or lower surface of the width part of the hoop material 1A, and the excess part of the plastically deformed part is notched and cut at a length 2b1 that is longer than the radial preparation length of the short pipe, leaving undetermined width parts 2b2 and 2c2, and then further cut at the preparation length to form a blank. The method for manufacturing a short pipe from a hoop material is disclosed by a series of manufacturing methods, which include forming a hoop 2A, bending the taper at a right angle 3a into a cylindrical body, positioning the undetermined portions 2b2 and 2c2 by clamping them with a jig, laser welding the butted portions, finishing the bead portions of the laser welds, press-cutting the undetermined portions 2b2 and 2c2 to match the end faces 7a2b of the cylindrical body, cleaning the inside and outside, and correcting the end faces and the cylindrical portion with a mold to complete the process. There is no disclosure of the means, actions, or effects of the assembly, joining, and supply device to the tube shrinking machine, or the supply method. Patent Document 3 has a problem in that it does not achieve any of the requirements of the present invention as a manufacturing device and manufacturing method for shrinking a metal hoop coil tube material in multiple steps to make it into a thin tube in the step-by-step tube shrinking process of a cylindrical tube, and the actions and effects corresponding to the requirements of the present invention. Furthermore, Patent Document 3 does not provide any configuration, action, or effect related to a means for continuously supplying a hoop-shaped coil material as in the present invention.

[0009] In Patent Document 3, the workpiece is not a hoop-shaped coiled pipe material, but a blank that is a flat plate, and the processing is for a workpiece that is not a hoop material. The differences between Patent Document 3 and the present invention are as follows. <Differences between Patent Document 3 and the present invention> As described in paragraph 0014 of Patent Document 3, "As described in FIG. 3, the two width portions of the hoop material are plastically formed into a blank 2A ​​as described in the second process, and then the blank is bent into a cylindrical body, welded, and finished." b... "Both widths of the hoop material are plastically formed to form blank 2A, which is then bent into a cylindrical body, welded, and finished." c. We were wondering if there was a manufacturing method that was easier and cheaper than using hoop material. As shown in the above example, the description of Patent Document 3 shows that Patent Document 3 differs from the present invention. Furthermore, Patent Document 3 has problems that are not related to the configuration, function, and effect of treating the circular pipe of the present invention.

[0010] Patent Document 4 discloses the following: "A pre-feed preparation device for coiled plate material to be installed in an electric resistance welded pipe production line, a thin steel plate supplying device for a punching machine, etc., which makes it possible to instantly follow the rear end of the preceding coil material via pinch rolls and supply it. An opener position is provided on the side parallel to the production line to which the preceding coil is supplied, and at this position a new coil 4b (hereinafter see Patent Document 4 for the number symbols) is prepared for supply on an opener cart 3 which can move on rails 1 in a direction perpendicular to the line. The cart is equipped with a lifting device 5 which supports and lifts the coil material, driving devices 11a, 11b which rotate the coil, a pair of opener arm devices 6 which sequentially pay out the coil tip from the production line side and guide it downstream, a side guide 9 which regulates the travel up to a stopper 8 which sets the payout amount, and a clamp device 20 which fixes the coil tip. After payout of the preceding coil is completed, the cart is moved into the line and attached to the uncoiler mandrel, making it possible to instantly follow it." However, there is no disclosure regarding the assembly, joining, and supplying device and method for the cylindrical coil hoop material to the tube shrinking machine.

[0011] In addition, Patent Document 4 targets plate strip material during processing, and although there is an idea of ​​"instantly following up to the rear end of the preceding coil material" and supplies it, it targets plate blanks during processing, and the "following" supply is different from the "continuous" supply of the present invention. The coil material is for "following" which is different, and there is a problem that there is no disclosure of the configuration, action, or effect of, for example, "continuous" supply, etc., for the problems and solutions of the present invention. There is no disclosure of the problems and solutions related to the supply device and supply method for the assembly, joining, and tube shrinking machine of the circular tube coil hoop material. Patent Document 4 has a problem that it does not achieve any of the requirements of the present invention and the actions and effects corresponding to the means and requirements of the present invention as a manufacturing device and manufacturing method for shrinking a metal hoop coil tube material in multiple steps to make it into a thin tube in the stepwise tube shrinking process of a cylindrical tube. In addition, Patent Document 4 does not have the configuration, action, or effect of the means for continuously supplying the hoop coil material, as in the present invention.

[0012] [Patent Document 1] Japanese Patent Application Publication No. 8-253927 [Patent Document 2] Japanese Patent Application Publication No. 3-35808 [Patent Document 3] Japanese Patent Application Publication No. 11-244936 [Patent Document 4] Japanese Patent Application Publication No. 6-198335 Summary of the Invention [Problem to be solved by the invention]

[0013] In the case of drawing, after a series of metal hoop-shaped coiled tubing materials are supplied to a processing machine, when the next series of metal hoop-shaped coiled tubing materials to be reduced is drawn out, the next newly supplied metal hoop-shaped coiled tubing material "is at the end, so no drawing force can be applied thereto." In other words, since there is no drawing force for the second, third, etc. stages of reduction, the second, third, etc. stages of reduction are essentially impossible. When a new series of metal hoop-shaped coiled tubing materials are reduced in multiple stages, there is a problem that the end of the new series of metal hoop-shaped coiled tubing materials must have a shape for the multi-stage reduction process used in mass production, for example, by external setup, as described below in paragraph 0016, etc., before the new series of metal hoop-shaped coiled tubing materials can be continuously fed into the continuous multi-stage reduction process. The present invention aims to solve this problem by continuously supplying a series of metal hoop-shaped coiled tubing materials to a processing machine after the series of metal hoop-shaped coiled tubing materials have been supplied to the processing machine, and to continuously supply and process a series of metal hoop-shaped coiled tubing materials while minimizing or reducing external setup that requires man-hours by skilled workers.

[0014] <Regarding the absence of a solution to the problem of the present invention in the background art and prior art> The problem is to continuously and continuously supply a metal hoop-shaped coil tube material of a "circular tube body" that did not exist in Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4, which were concluded to be closest in technical field and technical content to the present invention in a three-year survey conducted in the background art and in a J-PlatPat search conducted as of April 24, 2024, to a tube shrinking machine. However, there is no disclosure in the background art or prior art regarding the assembly, joining, and supply device and supply method to the tube shrinking machine. There is no disclosure of a means for solving the problem related to the supply device and supply method to the tube shrinking machine after assembling and joining the circular tube coil hoop material of the present invention technology. In the metal engineering and mechanical engineering fields of the Science and Technology Literature Bulletin, there is no disclosure of the problem, means, and effects of the present invention in a three-year survey conducted as of April 24, 2024.

[0015] <Outline of the problem that this invention solves> When a series of metal hoop-shaped coiled tube materials is supplied to a processing machine, and then the next series of metal hoop-shaped coiled tube materials are supplied to the processing machine in succession (although there is no prior art for this), there is a problem that stopping the processing machine and setting up the next series of metal hoop-shaped coiled tube materials for supply and setting the next series of metal hoop-shaped coiled tube materials in the processing machine requires a great deal of time and effort from a skilled technician. There is a problem that the processing cost increases. The supply setting up work requires many years of skill, and since it is manual work, not only does it take time to train personnel, but there are also cases where training is not possible even after time has passed, and even if personnel are trained to a certain extent, there is a problem that there is variation in initial processing quality and quality during operation. There is a problem that quality defects occur frequently. <Outline of the problem to be solved by this device II> For a processing machine, finishing a single process such as tube shrinking results in a large tube shrink in one process, which is not effective in terms of quality and is not efficient in terms of production. The more difficult the material is to process, the better the quality (less likely to cause quality defects such as cracks) and the more efficient it is in terms of production (short production time, maintenance, lubricant management, etc.) if the shoulder shown in 1C, 2C, 3D, and 4D in Figure 2C is formed in succession through the plastic flow of the material, and the process is formed in multiple stages of tube shrinking shape forming "little by little." Continuous multi-stage tube shrinking shape forming has the problem that it must operate continuously under specific conditions such as the work material, wall thickness, die shape, and processing feed speed. <Outline of the problem to be solved by this device III (specific essential problem i)> When a series of metal hoop-shaped coiled tube materials is fed into the processing machine following a series of metal hoop-shaped coiled tube materials, "the pulling force of the tube from the front of each die does not act at all on the next series of metal hoop-shaped coiled tube materials." In other words, "the next series of metal hoop-shaped coiled tube materials cannot be processed at all." As a result, until the pulling forces from the front of each die can act on the next series of metal hoop-shaped coiled tube materials, "a shape must be created by hand feeding and hand processing, that is, for example, a workpiece with shoulders 1C, 2C, 3D, and 4D in Figure 2C must be created [at the front] of the series of metal hoop-shaped coiled tube materials and placed on the processing machine," and "after the tip portions of the next series of metal hoop-shaped coiled tube materials are set in the processing machine so that the pulling forces from the front of each die are not too strong or too weak in accordance with quality requirements," a new continuous processing operation at mass production speed must be started. Until the pulling forces from the front of each die, including the pulling forces from the secondary winding and drawing out drive drum 421 (1 in Figs. 2A, 2B, and 2C), the tertiary winding and drawing out drive drum 431 (similar), and the quaternary winding and drawing out drive drum 441 (similar to D4) in Figs. 4a and 4b, are fully exerted on the tube (i.e., until mass production is possible), each die is removed from the continuous processing machine by manual processing, for example, in an external setup, and each die (for example, Figs. The only way to prepare for processing is to use other dies that are the same as the primary medium diameter reducing die 410, secondary medium diameter reducing die 420, and tertiary small diameter reducing die 430 in Figures 4a and 4b, or that are equivalent to them (for example, the primary medium diameter reducing die 410, secondary medium diameter reducing die 420, and tertiary small diameter reducing die 430 in Figures 4a and 4b), and artificially create such a relationship between the pulling force and each die in advance before mass production (it is most effective to pull from the dies by hand), and then prepare for processing using the external setup. Unless this is done, mass production and continuous processing will not be possible until 1C2C3D4D in Figure 2C is formed and the winding set around the primary medium diameter tube reduction die 410, secondary medium diameter tube reduction die 420, and tertiary small diameter tube reduction die 430 in Figures 4a and 4b of the processing machine, and the secondary winding and drawing out drive drum 421 (1 in Figures 2A, 2B, and 2C), tertiary winding and drawing out drive drum 431 (similar), and quaternary winding and drawing out drive drum 441 in Figures 4a and 4b, because there will be no pulling force on each die.This is a top priority, but it can be difficult to notice and can become a serious issue. <Outline of the problem to be solved by this device III (specific essential problem ii)> The front part of the pre-supply circular tubular coil hoop material body 301, such as the tube 307 in Fig. 3, is wound around the secondary winding and drawing drive drum 421 (1 in Fig. 2A, Fig. 2B, Fig. 2C), the tertiary winding and drawing drive drum 431 (similar), and the quaternary winding and drawing drive drum 441 (similar to D4) in Fig. 4a and Fig. 4b, so that the tubes 451, 452, 453, 454, and 455 are wound around the drums to apply drag and friction that converts the rotational force of the drum into a tangential drawing force by the principle of a pulley, despite the presence of lubricating oil from the vicinity of each die for processing. There was a serious problem that the front part of the pre-supply circular tubular coil hoop material body 301 must be accurately adjusted in shape to the entire process of the processing machine over a considerable length range of the front part of the pre-supply circular tubular coil hoop material body 301, and then the correct setting must be confirmed and continuous processing must be started. The purpose of this invention is to solve this serious problem that is difficult to notice. <Outline of the problem to be solved by this invention IV (iii as a specific essential problem, [overview of the above i ii from the perspective of function])> Since there is no pulling force on each die, there is a problem that it is necessary to match (match) all the step-by-step processing and forming in the series of processing machines, match all the length dimensions of the processing deformation and the several steps of forming process in the processing machine, for example, by manually setting up the external arrangements, accurately match the size, position, and shape of the work in the continuous processing machine to the size, position, and shape of the mass production processing device, including the die, and match all the shape forming steps with the production time while maintaining the strength of the tube wall thickness, which depends on the material strength, to be able to withstand the pulling force, and accurately form the tip of the next series of metal hoop-shaped coil tube material over a long distance of the tube material, and set it accurately to all the processes of the processing machine before starting to supply the tube material for mass production. This invention aims to solve this important problem that is difficult to notice.

[0016] <Outline of the problem to be solved by this invention V (specific essential problem iv, [above i, ii and iii from a functional perspective])> The above external setup requires highly skilled manual work to match the lengthwise dimensions with those during production, and requires the skill of a special process as defined by international standards. In addition, there is a problem that a great deal of setup time and labor is required before the next series of metal hoop-shaped coiled tubing materials can be supplied, even if they are not directly produced. Thus, there is a problem that a great deal of time and labor is required to set up the next series of metal hoop-shaped coiled tubing materials. Or, there is a problem that the next series of metal hoop-shaped coiled tubing materials cannot be processed at all. When the processing machine performs the drawing process to reduce the diameter in several stages, the first stage of tube diameter reduction must be performed from the tip of the next series of metal hoop coiled tube materials by external preparation such as manual processing, the first stage of tube diameter reduction must be performed by external preparation such as manual processing, the second stage of tube reduction must be performed by external preparation such as manual processing of the part that has been reduced in the first stage, and the next stage of tube reduction must be performed by external preparation such as manual processing of the next reduced tube part near the tip of the next series of metal hoop coiled tube materials by external preparation such as manual processing to complete the second stage of tube reduction, which results in an enormous increase in the number of setup steps, a large amount of setup time, and a problem of high skilled labor costs. However, there was no disclosure of a supply device or supply method for the assembly, joining, and tube reduction machine of the circular tube coil hoop material. There was no disclosure of a supply device for the assembly, joining, and tube reduction machine of the circular tube coil hoop material according to the present invention. <Outline of the problem to be solved by this device VI (specific essential problem v) Reasons why external arrangements are necessary> In this way, in the tube shrinking process, unless the force pulling the tube in the axial direction from the front is applied, all stages of tube shrinking cannot be performed at all. In other words, when a new tube coil hoop material is supplied, the force pulling the tube in the axial direction from the front is not applied to all the tube shrinking dies, so even if a new tube coil hoop material is pushed from the back, it cannot be processed at all. For this reason, after completely stopping the tube shrinking device, the mass production die is set to a turret type and removed, or the same die is used, for example, to pull the tube by hand against the die, and the tip of the new tube coil hoop material, which corresponds to 1C2C3D4D in Figure 2C, must be formed accurately to match the overall process dimensions of the processing machine as an external setup with the processing stopped. In other words, the primary medium-diameter reducing die 410, secondary medium-diameter reducing die 420, and tertiary small-diameter reducing die 430 in Figures 4a and 4b were removed from the processing machine, or replacement or maintenance dies were used to form each reduced tube, and then, at the locations corresponding to Sc and Sd in Figure 2C, an appropriate total winding amount and length were ensured, taking into account the resistance force due to the number of windings, etc., to obtain the necessary pulling force, taking into account the slippage of the lubricating oil for ease of processing during continuous processing, and then the tip of a new circular tubular coil hoop material corresponding to 1C2C3D4D had to be formed as an external setup by stopping processing and accurately matching the dimensions of the processing machine.

[0017] In addition to solving these problems, the present invention also aims to solve the problems described in the embodiments that were not detected in the background art and prior art. [Means for solving the problem]

In regard to mainly claim "1" etc., the means described below are not disclosed in Patent Documents 1, 2, 3, and 4, which were extracted as the closest, as of April 30, 2024, in the J-PlatPat search. In the mechanical engineering field of the Science and Technology Literature Bulletin, no disclosure regarding the problem, means, or effect of the present invention was found before April 30, 2024, after a three-year search.

[0019] <Explanation I of the means mainly relating to claim 2 etc.> This device is an assembly of one circular tubular coil hoop material 111 with the diameter of the tip reduced, and another circular tubular coil hoop material 131 combined with this one circular tubular coil hoop material 111 on the inside of the rear end, in which the contracted portion 112 of the circular tubular coil hoop material 111 and the tip portion of the other circular tubular coil hoop material 131 are formed by plastic deformation, and then joined to form an assembly, with the contracted portion 112 of the circular tubular coil hoop material 111 and the tip portion of the other circular tubular coil hoop material 131 being formed integrally. In order to solve such problems and issues, the present invention is an assembly of one circular tube coil hoop material 111 with the diameter of the front end reduced and another circular tube coil hoop material 131 combined with the rear end inside of the one circular tube coil hoop material 111, characterized in that the reduced part 112 of the circular tube coil hoop material 111 and the front end of the other circular tube coil hoop material 131 are assembled and joined by plastic deformation to form an assembly to be supplied to a tube reduction processing machine, and are formed as one body. Such an assembly is formed by plastic deformation, and the specific means will be described in detail in the embodiments described below together with the means, action, and effect. Since the means of forming such an assembly by plastic deformation is not an area where a production system for repeated mass production that requires jigs and equipment should be established, the streamlined shape of the front of the leading car of the Shinkansen is given by so-called manual "strike-out," which involves striking the contracted portion 112 of the cylindrical coil hoop material 111 with a hammer (a small hammer in the case of thin tube contraction), anvil, etc., to plastically deform the material. By using a material with the same hardness or similarity to the cylindrical coil hoop material as a buffer material and striking it with a hammer, the cylindrical coil hoop material can be subjected to plastic contraction processing in an off-site setup without damaging it. <Explanation II of the means mainly relating to claim 2 etc.> The means related to claim 2, etc., as shown in the embodiments described later, form the reduced portion 112 of the cylindrical coil hoop material 111 by plastic deformation using a shrinking die used for continuous mass production installed in a turret type and removed from the processing machine, or using a corresponding die prepared for replacement, maintenance, or other purposes, or by a manual processing center, etc. Hold the tubular coil hoop material 111 in one hand and remove the primary medium diameter reducing die 410, secondary medium diameter reducing die 420, and tertiary small diameter reducing die 430 in Figures 4a and 4b, which correspond to 1C2C3D4D of the workpiece in Figure 2C, from the processing machine, or hold replacement dies for the primary medium diameter reducing die 410, secondary medium diameter reducing die 420, and tertiary small diameter reducing die 430 in Figures 4a and 4b for replacement or maintenance in the other hand, pass the tubular coil hoop material 111 through the dies by hand, and pull the tubular coil hoop material that comes out of the die by hand, thereby passing it through the dies sequentially to form 1C2C3D4D in Figure 2C. <Explanation III of the means mainly related to claim 2 etc. (the tube shrinking action and mechanism according to the present invention)> In Fig. 2, 1 shows the secondary winding and drawing out driving drum 421 in Fig. 4, 2 shows the secondary winding and drawing out driving drum 421 in Fig. 4, 3 shows the tertiary winding and drawing out driving drum 431 in Fig. 4, and 4 shows the quaternary winding and drawing out driving drum 441 (D4) in Fig. 4, which are shown in schematic form for ease of understanding. The main means related to claim 2 etc. is a means for integrating one of the circular tubular coil hoop materials 111 with the other circular tubular coil hoop material 131 combined with the one circular tubular coil hoop material 111 at the inner rear end by fitting the assembled material with the contracted tube portion by plastic deformation, and supplying the assembled material to the secondary winding and drawing out driving drum 421, the tertiary winding and drawing out driving drum 431, and the quaternary winding and drawing out driving drum 441 (D4). <Technical positioning of the means mainly related to claim 2 etc.> In the background art, and in a J-PlatPat search, as of May 20, 2024, in Patent Documents 1, 2, 3, and 4, which are considered to be the closest in field to the present invention, the metal hoop-shaped coil tube material 111 (hereinafter, the number symbols related to the present invention are used in accordance with the <Explanation of Symbols> and other parts of this specification) of the "circular tube body" that did not exist in the patent document 1, patent document 2, patent document 3, and patent document 4, was not disclosed in the J-PlatPat search before May 20, 2024. In the Science and Technology Literature Bulletin Mechanical Engineering Field, as of May 20, 2024, there was no disclosure of the problem, means, and effect of the present invention.

[0020] <Explanation of the means mainly relating to claim 3 etc.> In order to solve such problems and issues, the present invention provides an assembly in which the contracted portion 112 of the cylindrical coil hoop material 111 and the rear end portion of the other cylindrical coil hoop material 131 are formed and assembled, and the assembly is joined by welding, brazing, or bonding with an adhesive to form a single unit. <Technical positioning of the means mainly related to claim 4 etc.> In the background art and in a J-PlatPat search as of May 20, 2024, a metal hoop-shaped coil tube material 111 (hereinafter, the number symbols related to this invention are used in accordance with the <Explanation of Symbols> and other parts of this specification) that did not exist in Patent Documents 1, 2, 3, and 4, which are considered to be closest in field to this invention, was not "followed" but was separately manufactured by "assembling" or "assembling, joining, and attaching to a tube shrinking machine. Regarding claim "4" and the like, the means described in detail below have not been disclosed before May 20, 2024 in a J-PlatPat search.

The means described below in detail mainly in relation to claim "4" etc., which mainly consists of forming and joining the contracted portion 112 of the cylindrical coil hoop material 111 and the tip portion of the other cylindrical coil hoop material 131 in a connected and "continuous" manner as a "supply device and supply method," and joining this assembly by welding, brazing, or bonding with an adhesive to form an integral body, and supplying it to a processing machine, has not been disclosed in a J-PlatPat search prior to May 20, 2024. A tube shrinking processing apparatus that supplies an assembly of a cylindrical coil hoop material as described in claims 1 to 4, which comprises a winding and drawing drive drum, a tube shrinking die, a cylindrical coil hoop material body before supply 301, a coil hoop winding body after tube shrinking 399, a cylindrical coil hoop material assembly supply drum 401, a cylindrical coil hoop material assembly tube shrinking coil hoop winding drum 402, and a winding and drawing drive drum, has not been disclosed in a J-PlatPat search prior to May 20, 2024.

[0022] <Summary of the main points of the device> As described above, the means according to all claims of the present invention is a means for integrating the assembly of one of the cylindrical coil hoop materials 111 with the other cylindrical coil hoop material 131 combined with the inside of the rear end, and continuously supplying it to the secondary winding and drawing-out drive drum 421, the tertiary winding and drawing-out drive drum 431, and the quaternary winding and drawing-out drive drum 441 (D4). Effect of the Invention

[0023] <Mainly the action and effect of claim 1, etc.> When one of the circular tube coil hoop materials 131 is supplied to the tube shrinking machine located on the right side of Figures 1 and 2, and the next new circular tube coil hoop material 111 is supplied, the circular tube coil hoop material 131 and the next new circular tube coil hoop material 111 are naturally not connected, so the vicinity of the tip of the next new circular tube coil hoop material 111 must be formed into the shape for continuous mass production by the tube shrinking machine located on the right side of Figure 2 (described later using Figure 4 and others) by external setup before starting the tube shrinking process of the next new circular tube coil hoop material 111 by the tube shrinking machine. This has the effect of eliminating the need for this external setup work. This has the effect of significantly reducing the number of steps and the processing costs by eliminating the need for this manual external setup work that requires advanced adjustment skills. When the shrinking process of the other cylindrical coil hoop material 131 is completed, the one-end shrinking process is completed, and the front end of one cylindrical coil hoop material 111 is prepared for shrinking by fitting it to the primary large diameter shrinking die 410, the secondary medium diameter shrinking die 420, and the tertiary small diameter shrinking die 430, with the length dimensions accurately matching the processing equipment, and the winding around the secondary winding and drawing drive drum 421, the tertiary winding and drawing drive drum 431, and the quaternary winding and drawing drive drum 441 (D4) is accurately matching the length dimensions with the processing equipment, eliminating the need for preparatory processing prior to smooth continuous processing. These means, actions, and effects did not exist in the prior art or background art. In this device, the tip portion of one cylindrical tubular coil hoop material 111 is assembled with the other cylindrical tubular coil hoop material 131 on the inside of the rear end and supplied to a tube shrinking processing machine located to the right of Figures 1 and 2.After the continuous processing of the other cylindrical tubular coil hoop material 131 has been completed, as described below, the tip portion of the next newly supplied cylindrical tubular coil hoop material 111 is adjusted to the shape of the peripheral tip of the workpiece, which is typically equivalent to Figure 2C during mass production, through the primary large diameter tube shrinking die 410, secondary medium diameter tube shrinking die 420, and tertiary small diameter tube shrinking die 430 in Figure 4, as described below.This eliminates the need for manual external setup work that requires advanced adjustment skills, thereby significantly reducing labor and processing costs.By assembling the outer shape DS of one of the circular tube coil hoop materials 111 and the outer shape DL of the other circular tube coil hoop material 131 in agreement, the effect of smoothing the supply continuity of one of the circular tube coil hoop materials 111 to the tube shrinking machine (at each winding drum and its vicinity, during the process of passing through each die, etc.) following the other circular tube coil hoop material 131 is achieved. In addition, the effect of significantly reducing the external setup when continuously supplying one of the circular tube coil hoop materials 111 to the tube shrinking machine following the other circular tube coil hoop material 131 is achieved. The continuous multi-stage tube shrinking shape forming has a problem that the continuous multi-stage shape forming operation must be performed only under specific conditions such as the material of the workpiece, the wall thickness, the shape of the die, the processing feed speed, etc., but the present invention has the effect of being able to perform the tube shrinking of a new one of the circular tube coil hoop materials 111 under the same conditions as the specific speed conditions set at the beginning regarding the material of the workpiece, the wall thickness, the shape of the die, the processing feed speed, etc. This has the effect of eliminating the need for work to prepare for production by first determining conditions such as specific speeds for new die shapes, processing feed speeds, etc.

[0024] <Effects and Effects Mainly Concerning Claim 2, etc.> By plastic deformation, the contracted portion 112 of the circular tubular coil hoop material 111 and the tip portion of the other circular tubular coil hoop material 131 are formed, and then joined to form an assembly. By integrally forming the contracted portion 112 of the circular tubular coil hoop material 111 and the tip portion of the other circular tubular coil hoop material 131, in addition to the <actions and effects mainly related to claim 1, etc.>, it is possible to reduce the amount of manual labor requiring special skills during external setup, make the work easier, speed up the work, reduce labor costs, and enable a more stable supply of the circular tubular coil hoop material to the contraction processing machine. By forming the tube shrinking portion 112 of the cylindrical coil hoop material 111 and the tip end of the other cylindrical coil hoop material 131 by plastic deformation and joining them to form an assembly, and assembling the outer shape DS of one cylindrical coil hoop material 111 and the outer shape DL of the other cylindrical coil hoop material 131 so that they match, the effect of smoother supply continuity of one cylindrical coil hoop material 111 to the tube shrinking machine following the other cylindrical coil hoop material 131 (in the process of passing through each winding drum and its vicinity, each die, etc.) is achieved compared to claim 1. Also, the effect of significantly reducing the external setup required when continuously supplying one cylindrical coil hoop material 111 to the tube shrinking machine following the other cylindrical coil hoop material 131 is achieved compared to claim 1. When the shrinking process of the other cylindrical coil hoop material 131 is completed, the one-end shrinking process is completed, and the front end of one cylindrical coil hoop material 111 is prepared for shrinking by fitting it to the primary large diameter shrinking die 410, the secondary medium diameter shrinking die 420, and the tertiary small diameter shrinking die 430, with the length dimensions accurately matching the processing equipment, and the winding around the secondary winding and drawing drive drum 421, the tertiary winding and drawing drive drum 431, and the quaternary winding and drawing drive drum 441 (D4) is accurately matching the length dimensions with the processing equipment, eliminating the need for preparatory processing prior to smooth continuous processing. These means, actions, and effects did not exist in the prior art or background art.The present invention, mainly related to claim 2, forms the shrinking portion 112 of the cylindrical coil hoop material 111 and the tip end of the other cylindrical coil hoop material 131 by plastic deformation, and joins them to form an assembly. The shrinking portion 112 of the cylindrical coil hoop material 111 and the tip end of the other cylindrical coil hoop material 131 are integrally formed. After the continuous processing of the other cylindrical coil hoop material 131 is completed, as described below, the tip end of one of the cylindrical coil hoop materials 111 to be newly supplied next is fed into the primary large diameter shrinking die 410 and the secondary medium diameter shrinking die 420 in FIG. 4 described below. The process of reducing the peripheral shape of the workpiece tip of the circular tubular coil hoop material 111, which corresponds to FIG. 2C during mass production, by manual external setup work requiring advanced adjustment skills, using the die 420 and the tertiary small diameter tube reduction die 430, corresponds to 1C, 2C, 3D, and 4D in FIG. 2C is no longer necessary, resulting in a significant reduction in labor hours, labor costs, and reduction in labor costs due to manual setup work (in this type of processing area, automating the setup work has a low investment return, so business management decisions tend to depend on expertise), as well as reduction in processing costs such as lubricant consumption. In this way, by forming the contracted portion 112 of the circular tubular coil hoop material 111 and the tip portion of the other circular tubular coil hoop material 131 through plastic deformation, and joining them to form an assembly, the contracted portion 112 of the circular tubular coil hoop material 111 and the tip portion of the other circular tubular coil hoop material 131 are integrally formed, which results in a significant reduction in labor hours, labor costs, and processing costs such as lubricant consumption due to manual setup.

[0025] <Effects mainly related to claim 3, etc.> The tube-reduced portion 112 of the cylindrical coil hoop material 111 and the tip portion of the other cylindrical coil hoop material 131 are formed and joined to form an assembly. By joining and forming this assembly integrally by welding, brazing, or bonding with an adhesive, the joining of the tube-reduced portion 112 of the cylindrical coil hoop material 111 and the other cylindrical coil hoop material 131 becomes strong, and the effect of improving workability during setup and production is achieved. The effect of reducing the number of steps in setup and production and reducing production costs is achieved. In the embodiment in which welding and brazing are performed, the effect of the cylindrical coil hoop material 111 and the other cylindrical coil hoop material 131 being joined more strongly is achieved. In the embodiment in which the assembly is joined and formed integrally by bonding with an adhesive, the effect of joining can be achieved at a lower cost, with simpler jigs and tools, and with fewer steps, and the effect of reducing the number of steps in the external setup and processing preparation process. When the shrinking process of the other circular tubular coil hoop material 131 is completed, one end shrinking process is completed, and the tip of one of the circular tubular coil hoop materials 111 is prepared for shrinking process by matching it with the primary large diameter shrinking die 410, the secondary medium diameter shrinking die 420, and the tertiary small diameter shrinking die 430 to accurately match the length dimensions of the processing equipment, and winding it around the secondary winding and drawing out drive drum 421, the tertiary winding and drawing out drive drum 431, and the quaternary winding and drawing out drive drum 441 (D4) to accurately match the length dimensions of the processing equipment, thereby eliminating or reducing the need for preparatory processing prior to smooth continuous processing. In the embodiment of welding and brazing, the circular tube coil hoop material 111 and the other circular tube coil hoop material 131 are more strongly joined, so that the processing conditions for supplying a new circular tube coil hoop material and the adjustment of the processing machine can be set in a shorter time, and stable high quality can be easily provided. These means, actions, and effects did not exist in the prior art or background art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] <Mode for carrying out the invention mainly relating to claim 1 etc.> The means for solving the problem of the present invention will be explained with reference to Figures 1a and 1b. Figures 1a and 1b show a schematic cross-section of a supply device and supply means for an "assembly" or "assembly, joining, and tube shrinking processing machine for "assembling" or "joining" metal hoop coiled tube materials and supplying them to the processing machine in a connected and "continuous" manner. Circular tube coil hoop materials are convenient for mass production, but when one circular tube coil hoop material is put into the processing machine and used, a new circular tube coil hoop material must be set in the processing machine and processed, which is a natural manufacturing method. <Means, configurations, functions, actions, and effects according to Figs. 1a and 1b of the embodiment related to claim 1 etc.> 1a and 1b, the circular tubular coil hoop material is fed from the right to the left in the order of the right part of the figure into the processing machine further to the right of the figure, and 111 is a circular tubular coil hoop material that corresponds to another new circular tubular coil hoop material. 112 is a contracted portion obtained by contracting the tip of the circular tubular coil hoop material, and 131 is the other circular tubular coil hoop material that was processed before the circular tubular coil hoop material 111. The circular tubular coil hoop material 111 has a smaller tube diameter DSH than the tube diameter DS of the circular tubular coil hoop material 111 near the tip. In the embodiment of Fig. 1, as an example only, an embodiment of the contracted tube portion 112 in which the tube diameter DS of the circular tubular coil hoop material 111 and the outer diameter of the contracted tube portion near the tip are nearly equal is described, but Fig. 1 merely shows the present invention in a schematic manner, and even if the outer diameter of the contracted tube portion 112 is larger or smaller than that of Fig. 1, the function and effect of the present invention are achieved by making the tube diameter DSH smaller than the tube diameter DS of the circular tubular coil hoop material 111. In the embodiment in which the tube diameter DSH is smaller than the tube diameter DS of the circular tubular coil hoop material 111, the thickness of the narrowed shoulder portion near the boundary between the contracted tube portion 112 and the circular tubular coil hoop material 111 can be made larger than that of the embodiment of Fig. 1. By making the wall thickness larger than that of the embodiment of FIG. 1, the integrated strength of the tube shrinking portion 112 with respect to the tube shrinking hoop material 111 can be increased (by making the wall thickness larger), and there is an effect of facilitating the processing and manufacturing of the tube shrinking portion 112 in terms of plastic deformation. In addition, when one tube coil hoop material is put into the tube shrinking processing machine and used, a new tube coil hoop material is set in the processing machine, and when the processing is performed, the shoulder portion is not broken, and the workability of the entire processing changeover work is improved. As means, functions, actions, and effects that did not exist in the conventional examples other than the present invention and the patent documents described in the prior art documents, the present invention has the function, action, and effect of dramatically and easily supplying the tube metal hoop coil material 111 to the processing machine in succession by "following" the other tube coil hoop material 131 that was previously processed.After the other circular tubular coil hoop material 131 is supplied to the processing machine, the front end of the circular tubular metal hoop-shaped coil tube material 111 is changed over, and the entire process of the processing machine and the front end preparation of the circular tubular coil hoop material 111 corresponding to the entire process of the processing machine in the external setup are set up in accordance with all the processes of the processing machine so that continuous processing can be performed in the external setup, and the enormous amount of work required for various processing preparation work for the next continuous mass production is eliminated or drastically reduced. (The enormous workload that must be resolved for the front end of the circular tubular metal hoop-shaped coil tube material 111 is changed over, and the entire process of the processing machine and the front end preparation of the circular tubular coil hoop material 111 corresponding to the entire process of the processing machine in the external setup are set up in accordance with all the processes of the processing machine so that continuous processing can be performed in the external setup, and the enormous amount of work required for various processing preparation work for the next continuous mass production is described later.)

[0031] <Means, configurations, functions, actions, and effects of each claim and embodiment of the present invention other than those described in the immediately preceding paragraph> Next, the claims and embodiments of the present invention will be explained using Fig. 1. The means, configuration, function, action, and effect of the claims and embodiments of the present invention other than those described in the immediately preceding paragraph will be explained using Fig. 1a and Fig. 1b. In Fig. 1a and Fig. 1b, 127 indicates a welded portion that joins the cylindrical coil hoop material 111 and the other cylindrical coil hoop material 131 by welding, brazing, or soldering. 129 indicates a welded portion with the special portion removed. In this way, after forming the welded portion, 129 changes the setup of the tip of the metal hoop-shaped coil tube material 111 of the cylindrical body described later, and in the process of the enormous amount of work in which the entire process of the processing machine and the forward preparation processing conditions of the cylindrical coil hoop material 111 corresponding to the entire process of the processing machine in the external setup are set in accordance with all the processes of the processing machine so that it can be processed continuously with external setup, and the feeding of the cylindrical coil hoop material 111 and the other cylindrical coil hoop material 131 is not stopped when they are fed into the processing machine after external setup, during mass production, the special portions relative to the outer shape DS of one cylindrical coil hoop material and the outer shape DL of the other cylindrical coil hoop material are removed so that they match the outer shape DS of one cylindrical coil hoop material and the outer shape DL of the other cylindrical coil hoop material.

[0032] 1a and 1b, 121 is a tube-reduced portion near the tip of the cylindrical coil hoop material. As shown in Fig. 1a and 1b, the vicinity of the tip of the cylindrical coil hoop material 111 is, for example, removed from a single or multiple dies of a processing machine, and is shrunk by a jig or manual processing in a separate external setup, as described later in detail, to reduce the outer shape DS of one cylindrical coil hoop material before shrinking to the outer shape DSH after shrinking. <Means, actions, and effects mainly related to the embodiments of claim 2 etc.> Since the means of forming such an assembly by plastic deformation is not an area where a mass-production system should be established, a method similar to the so-called "hammering" method used by hand to finish the front shape of the leading car of the Shinkansen into a streamlined shape is used, in which the tube-contracted portion 112 of the tube coil hoop material 111 is struck and plastically deformed with a hammer (a small hammer in the case of thin tube contraction), an anvil, etc. In the tube-contraction process during external setup by such plastic deformation, solvents and chemical substances are not used much, which has the effect of reducing additional labor hours for cleaning, etc. A material with the same or similar hardness as the tube coil hoop material, or a material softer than the tube coil hoop material, is used as a buffer material, and by striking the material with a hammer, the tube coil hoop material can be contracted, assembled, and joined without being damaged.

[0033] <Each claim and embodiment of the present invention in which the connection is made by brazing or soldering and then inserted into a processing machine> By melting an alloy (brazing filler) with a lower melting point than the circular tubular coil hoop material 111 and the reduced tube portion 121 near the tip of the circular tubular coil hoop material and using it as a kind of adhesive, the circular tubular coil hoop material 111 and the reduced tube portion 121 near the tip of the circular tubular coil hoop material are welded and joined without melting them themselves, in this embodiment of the present invention, it has the function, action and effect of being able to supply the circular tubular metal hoop-shaped coil tube material 111, which is a circular tubular body, to the processing machine located on the outside right side of the drawings in Figures 1a and 1b continuously, dramatically easily and with high productivity, ``following'' the other circular tubular coil hoop material 131 that was previously processed. Even if the vicinity of the tip of the cylindrical coil hoop material 111 is shrunk as shown in 112, fitted and assembled with the other cylindrical coil hoop material 131, and supplied to the processing machine located on the outer right side of Figures 1a and 1b in an unjoined state, it has the effect of significantly simplifying the external setup required for newly supplying a new cylindrical coil hoop material 111 to the processing machine, as in other methods. However, such joining by brazing or the like has the effect of improving quality, reducing costs, and significantly improving workability in the production preparation process in which multiple stages of shrunk are formed near the tip of the cylindrical coil hoop material 111, as in other methods, by external setup. In contrast to brazing, by shrinking the vicinity of the tip of the cylindrical coil hoop material 111 as shown at 112 by so-called welding, fitting, assembling and joining to the other cylindrical coil hoop material 131, when supplying a new cylindrical coil hoop material 111 to a processing machine, the effect of significantly simplifying the external setup as in other techniques is achieved, but as with such joining by brazing or the like, the workability is further improved significantly in the production preparation process in which multiple-stage shrinking similar to mass production processing is formed by external setup near the tip of the cylindrical coil hoop material 111 as in other techniques. In the embodiment of brazing, by burning flammable gas or using an electric heater, the effect of joining is achieved that is easier and more efficient than welding.Even in the embodiment in which the vicinity of the tip of the cylindrical coil hoop material 111 is compressed as shown in 112 by soldering, and then fitted, assembled, and joined to the other cylindrical coil hoop material 131, when a new cylindrical coil hoop material 111 is supplied to a processing machine, the effect of significantly simplifying the external setup as in other techniques is achieved. However, compared to such joining by brazing, etc., the workability is further improved in the production preparation process in which the vicinity of the tip of the cylindrical coil hoop material 111 is formed by multiple stages of compression similar to mass production processing by external setup as in other techniques. In the embodiment of the present invention, silver brazing, copper brazing, brass brazing, phosphorus copper brazing, aluminum brazing, etc. achieve the above-mentioned effects. Such joining by brazing, etc. in the external setup of the cylindrical coil hoop material 111 and the other cylindrical coil hoop material 131 is more effective when the tube diameter is relatively large. The following paragraphs will describe an embodiment of a connected cylindrical coil hoop material in which a cylindrical coil hoop material 111 and another cylindrical coil hoop material 131 are connected by a bonding adhesive in an external setup and then fed into a processing machine.

[0034] <Each claim and embodiment of the present invention in which the connection is made with adhesive and then put into the processing machine> Next, in Fig. 1a and Fig. 1b, in addition to the embodiment in which each part of 127, 129, 135, and 125 is formed by a welding system, the brazing, and the soldering as described above, there is an embodiment in which it is formed by an adhesive. In the embodiment in which it is formed by an adhesive, the connecting process of the circular tube coil hoop material 111 and the other circular tube coil hoop material 131 has the effect of not requiring a high-temperature device, the connecting work is simple, and the connecting can be performed with a small number of steps. When the circular tube coil hoop material 111 and the other circular tube coil hoop material 131 are connected and the circular tube coil hoop material 111 and the other circular tube coil hoop material 131 are put into the processing machine to the right of the circular tube coil hoop material 111 and the other circular tube coil hoop material 131, even if the tube coil hoop material 111 and the other circular tube coil hoop material 131 are not connected and assembled, the setup work may be completed without a high-strength connection, and the effects of not requiring a high-temperature device, the connecting work is simple, and the connecting can be performed with a small number of steps are greatly achieved.

[0035] The cylindrical coil hoop material 111 and the other cylindrical coil hoop material 131 in Fig. 1a and Fig. 1b are frequently processed with metal-based materials. For this reason, in Fig. 1a and Fig. 1b, an embodiment in which parts 127, 129, 135, and 125 are provided with instant adhesives for metals, epoxy resin adhesives, elastic adhesives, etc., is effective for forming a joint in the external preparation of the cylindrical coil hoop material 111 and the other cylindrical coil hoop material 131. This is effective for the ease of work, shortening the work process, and maintaining and improving the quality of tube shrinkage in the production preparation process of putting the material into the processing machine further to the right of Fig. 1a and Fig. 1b, and the process of processing with the processing machine. As for the specific names of adhesives used, since this is related to the use of registered trademarks, it is only stated that instant adhesives for metals, epoxy resin adhesives, and elastic adhesives are particularly effective as described above. Parts 125 and 135 are formed with instant adhesives for metals, epoxy resin adhesives, and elastic adhesives. In an embodiment in which parts 125 and 135 are formed using an instant adhesive for metals, an epoxy resin adhesive, or an elastic adhesive, no large-scale jigs and tools are required for joining, and the circular tubular coil hoop material 111 and the other circular tubular coil hoop material 131 can be joined at low cost using light jigs and tools, thereby reducing the amount of setup work and improving production efficiency.

[0036] Next, the above-mentioned problems and seriousness of the problems will be explained with reference to FIG. 2. FIG. 2 is a schematic diagram showing a cross section of a workpiece that is gradually reduced in size, and a towing drum that conveys the drawing force in the drawing process in the drawing process in several stages of the processing machine. In the case of drawing, when a series of metal hoop coiled tube materials are supplied to the processing machine and then the next series of metal hoop coiled tube materials are drawn out, the tip of the metal hoop coiled tube material is the first, and the tip portion that should be continuously processed cannot be processed at all. In other words, the next series of metal hoop coiled tube materials cannot be processed from the start of the first stage of drawing. Therefore, all of the reduced shoulder portions, including the reduced shoulder portion 1A in the first stage in FIG. 2A, cannot be reduced. Continuous processing is not possible. For this reason, a problem arises in that the die corresponding to 1A set in the processing machine is manually formed and set in the reducing processing machine by external setup, and only when the die is set in a state in which the drawing force is applied to all the reduced dies, the continuous reduction operation can be started.

[0037] The only way to prepare the tip of the next series of metal hoop coiled tube materials for processing machines was to obtain the metal hoop coiled tube materials and form the vicinity of the tip of the next series of metal hoop coiled tube materials by the most efficient actual tracing to the dimensions of the tube shrinking processing machine. Even when manually preparing the vicinity of the tip and preparing the series of parts to be formed, even the efficient actual tracing positioning for locating where to perform the preparation processing required many years of skill, and the entire process of forming the vicinity of the tip of the next series of metal hoop coiled tube materials took dozens of times longer than the above positioning, which was a major problem in production and processing.

[0038] In FIG. 2, A is a schematic cross-sectional view showing stepwise tube shrinking during mass production and setup according to all claims and all embodiments of the present invention, and is a schematic cross-sectional view showing one-stage tube shrinking. After a series of metal hoop-shaped coiled tube materials are supplied to a processing machine, the processing machine is stopped and the next series of metal hoop-shaped coiled tube materials are supplied to the processing machine. This is a schematic diagram of the first stage of tube shrinking shoulder portion 1A of the drawing process being made during external setup when the processing machine is stopped and the next series of metal hoop-shaped coiled tube materials are supplied to the processing machine. The first stage tube shrinking shoulder portion 1A is formed by manual pulling force, which does not require equipment and can be performed reliably, through a die corresponding to 1A set on the processing machine, only during external setup. The towing drum 1 symbolically indicates the time when the tube workpiece is set exactly to the device-derived length when the tube workpiece is set on the tube shrinking processing machine as a guide. In FIG. 2A, a first-stage tube-reduced shoulder portion 1A is formed on the next series of metal hoop-shaped coiled tube materials by external setup of the processing machine.

[0039] FIG. 2B is a schematic cross-sectional view showing stepwise tube shrinking during mass production and setup according to all claims and all embodiments of the present invention, and is a schematic cross-sectional view showing two-stage tube shrinking. After a series of metal hoop coiled tube materials are supplied to a tube shrinking machine, when the next series of metal hoop coiled tube materials are supplied to the tube shrinking machine, the tube shrinking machine is stopped, and in the external setup for the supply setup work of the next series of metal hoop coiled tube materials, the first stage tube shrinking shoulder portion 1A of the first stage tube shrinking shoulder portion of the drawing process is reduced by one stage from 1A, and the die corresponding to 2B of the tube shrinking machine or the die for shrinking 2B of the tube shrinking machine is removed, and the tube shrinking shoulder portion 2B is formed manually. In this way, the tube shrinking shoulder portion 2B is formed manually at a position separated by the dimension Sb from the tube shrinking machine, and the length is precisely matched to the tube shrinking machine, which is efficiently passed through the tube shrinking machine to match the actual product. In this manner, the shoulder portion 1A is crimped into the shoulder portion 2B.

[0040] In this way, the second stage shoulder portion 2B is formed manually using a die corresponding to the second stage shoulder portion 2B set in the tube shrinking machine. The dimension SB is made to match the dimension SB of the tube shrinking machine. For this reason, the second stage shoulder portion 2B is formed manually using a die corresponding to or identical to the shoulder portion 2B of the tube shrinking machine. The towing drum 1 and the towing drum 2 symbolically indicate the time when the workpiece is set in the tube shrinking machine with the length perfectly adjusted. In FIG. 2B, the first stage shoulder portion 1A and the second stage shoulder portion 2B are formed on the next series of metal hoop-shaped coiled tube materials in the series of metal hoop-shaped coiled tube materials in the external setup of the tube shrinking machine so that the workpiece matches the dimension SB of the tube shrinking machine. The tube is passed through an actual tube shrinking machine, the position is determined, and the second-stage tube shrinking shoulder portion 2B is formed to match the dimension SB of the tube shrinking machine using an equivalent die of the second-stage tube shrinking shoulder portion 2B of the tube shrinking machine, or a die equivalent to the second-stage tube shrinking shoulder portion 2B removed from the tube shrinking machine.

[0041] Fig. 2C is a schematic cross-sectional view showing the stepwise tube shrinking during setup in mass production according to all claims and all embodiments of the present invention, which is a schematic cross-sectional view showing four stages of tube shrinking. This is a schematic view of the external setup when the tube shrinking machine is stopped and the next series of metal hoop-shaped coiled tube material is supplied and setup work is performed, and the first stage of drawing process is used to make the tube shrink shoulder without a die. After a series of metal hoop-shaped coil tube materials are fed to the tube shrinking machine on the right side of Fig. 1 (the rear end of the feed becomes the other circular tubular coil hoop material 131), when the next series of metal hoop-shaped coil tube materials of the new metal hoop-shaped coil tube materials are fed to the tube shrinking machine, the tube shrinking machine must be stopped, and the tip of the next series of metal hoop-shaped coil tube materials (which will become the circular tubular coil hoop material 111 to be fed) must be formed at a non-mass production level for the tube shrinking machine (to apply a tensile force to each die) in the external setup preparation work near the tip of the next series of metal hoop-shaped coil tube materials (which will become the circular tubular coil hoop material 111 to be fed), for example, the tip of the circular tubular coil hoop material 111 to be fed, which consists of shoulders 1C, 2C, 3D, and 4D of the tube material shown in Fig. 2C, must be formed at a non-mass production level for the tube shrinking machine, and external setup preparation work must be performed. This invention solves this problem. Fig. 2C is a schematic diagram showing the gist of the invention as explained above, and as an embodiment, in order to match the dimensions of the actual tube shrinking machine shown in Fig. 6, the Sc dimension of Fig. 2C is made long, and within the Sc dimension, for example, the drum 2 is rotated one or more times, and the tip portion (shoulder portion 1C, 2C portion, etc.) of the cylindrical coil hoop material 111 to be supplied, which is composed of shoulder portions 1C, 2C, 3D, and 4D, is advanced to the right in the figure by driving the drum 2 to rotate right, and the cylindrical coil hoop material 111 is continuously shrink-conveyed. Fig. 2C, Fig. 2B, and Fig. 2A are schematic diagrams showing the tube shrinking process of the cylindrical coil hoop material, and the dies for shrinking the shoulder portions 1C, 2C, 3D, and 4D are not shown in Fig. 2C, Fig. 2B, and Fig. 2A, as they will be described later in Fig. 5, etc.

[0042] Next, all claims and all embodiments of the present invention will be described with reference to Fig. 3. Fig. 3 is a perspective view showing a supply side circular tubular coil hoop material and a final finished circular tubular coil hoop material after a series of processes such as tube shrinking according to all claims and all embodiments of the present invention. Fig. 3A is a perspective view showing a supply side circular tubular coil hoop material such as one circular tubular coil hoop material 111 and the other circular tubular coil hoop material 131 according to all claims and all embodiments of the present invention. Fig. 3B is a perspective view showing a final finished circular tubular coil hoop material after a series of processes such as tube shrinking according to all claims and all embodiments of the present invention.

[0043] <Description of the background, problems, and solutions of the present invention that cannot be solved even with the background art and means not found in the prior art relating to all claims and embodiments of the present invention ▲1▼> 3A and 3B, the background that cannot be solved even with the means that did not exist in the background art and the prior art will be described. 301 is a pre-supply circular tube coil hoop material, and 399 is a coil hoop winding body after tube shrinking. In Fig. 3A and Fig. 3B, while the pre-supply circular tube coil hoop material body 301 is rotated in the direction of arrow 314, the pre-contraction pipe 307, which has a relatively large diameter before contraction and is supplied to the tube shrinking machine installed on the right side of Fig. 3A and Fig. 3B, is supplied to the tube shrinking machine installed on the right side of Fig. 3A and Fig. 3B via positioning guide bodies 303 and 305. 3A and 3B, a post-reducing coil hoop take-up body 399 is rotated in the directions of arrows 310 and 311 while a post-reducing tube 306 having a relatively small diameter is wound after reduc- tion supplied from a reduc- tion machine installed on the left side of Figs. 3A and 3B while rotating the coil hoop take-up body 399 in the directions of arrows 310 and 311. The post-reducing tube 306 having a relatively small diameter is rotated around a fourth winding and drawing out driving drum 441 (D4), and the fourth winding and drawing out driving drum 441 (D4) is rotated and driven in the direction of arrow 309 to apply a pulling force in the direction of arrow 333, and the tube 308 before the fourth die ds4 is forcibly passed through the fourth die ds4 to complete the fourth reduc- tion as a post-reducing tube 306 having a relatively small diameter.

[0044] <Description of the background, problems, and solutions of the present invention that cannot be solved even with the background art and means not found in the prior art relating to all claims and embodiments of the present invention ▲2▼> In Figures 4a and 4b, 401 is a cylindrical coil hoop material assembly supply drum, and 402 is a cylindrical coil hoop material assembly shrink coil hoop winding drum. The cylindrical coil hoop material as a material is subjected to shrink processing from left to right in Figures 4a and 4b, and the material with a large tube diameter on the cylindrical coil hoop material assembly supply drum 401 is shrinked stepwise, and the most shrink-edged processed product is wound on the cylindrical coil hoop material assembly shrink coil hoop winding drum 402. The worker 480, in a position as shown in Figure 4a, has the function and effect of replacing the cylindrical coil hoop material 131 from the other cylindrical coil hoop material 131 supply to the cylindrical coil hoop material 111 as the cylindrical coil hoop material assembly supply drum 401 in an external setup, or of monitoring and troubleshooting during continuous shrink production processing.

[0045] <Functions, actions, and effects of all claims and all embodiments of the present invention in the preceding paragraph 0044> In Figures 4a and 4b, 411 is a primary winding and drawing out drive drum, 403 is a vertical and horizontal positioning guide, and 450 is a large diameter tube before shrinking. The large diameter tube before shrinking 450 wound around the assembly supply drum 401 of the circular tube coil hoop material is wound around the primary winding and drawing out drive drum 411, and the primary winding and drawing out drive drum 411 is rotated in the direction of the arrow 4111, whereby the large diameter tube before shrinking 450, which is a material with a large tube diameter on the side of the assembly supply drum 401 of the tube coil hoop material, is pulled toward the primary large diameter shrinking die 410 from the upper parallel (tangential) contact point of the primary winding and drawing out drive drum 411 against the resistance of the vertical and horizontal positioning guide 403. As the tube is pulled, it is positioned and guided in the vertical and horizontal directions by the vertical and horizontal positioning guides 403, and the pre-shrinking large diameter tube 450 and tube 452 are positioned and guided in a more straight line relative to tubes 453, 453, 454, etc., which has the effect of maintaining high quality of the tube shrinkage (tube diameter, wall thickness, cylindricity, coaxiality, concentricity, straightness, etc.). When there is material unevenness in the pre-shrinking large diameter tube 450, this has the effect of preventing defects due to breakage, cracks, etc. of the tube due to material unevenness in the pre-shrinking large diameter tube 450. This has the effect of reducing processing stoppages and production downtime due to breakage, cracks, etc. of the tube due to material unevenness.

[0046] [1 Functions, actions, and effects of the means around the secondary winding and drawing drive drum 421 related to tube shrinkage, etc.] The large diameter tubes 450, 451, 452, 453 before shrinking that were wound around the assembly supply drum 401 of the circular tube coil hoop material are wound around the secondary winding and drawing drive drum 421, and the secondary winding and drawing drive drum 421 is rotated in the same direction as the arrow 4111 to pull the tubes 451, 452 from the upper parallel (tangential) contact point of the secondary winding and drawing drive drum 421 against the resistance of the primary large diameter shrinking die 410 toward the secondary medium diameter shrinking die 420. By this pulling, the tube 452 is reduced to tube 453 by the secondary shrinking die 410. [2 Functions, actions, and effects of the means around the tertiary winding and drawing drive drum 431, etc.] The tubes 453, 454 are wound around the tertiary winding and drawing drive drum 431, and the tertiary winding and drawing drive drum 431 is rotated in the same direction as the arrow 4111, whereby the tubes 453, 454 are pulled along the tertiary tube reducing die 430 from the upper parallel (tangential) contact point of the tertiary winding and drawing drive drum 431 against the resistance of the secondary tube reducing die 420. By this pulling, the tube 453 is reduced to the tube 454 by the secondary tube reducing die 420. [3 Functions, actions, and effects of the means around the quaternary winding and drawing drive drum 441 related to tube shrinkage, etc.] The tubes 455, 460 are wound around the quaternary winding and drawing-out driving drum 441, and the quaternary winding and drawing-out driving drum 441 is rotated in the same direction as the arrow 4111, whereby the tubes 455, 460 are pulled from the upper parallel contact point of the quaternary winding and drawing-out driving drum 441 toward the cylindrical tube coil hoop material assembly tube-reducing coil hoop winding drum 402 against the resistance of the tertiary tube-reducing die 430. By this pulling, the tube 454 is reduced to the tube 455 by the tertiary tube-reducing die 430. The tube 455 is wound around the quaternary winding and drawing-out driving drum 441, and a drawing tensile force is applied to the tube 455. Thereafter, the tube 460 is rotated in the direction of the arrow 4021 by the circular tube coil hoop material assembly shrink coil hoop winding drum 402, and is wound up on the circular tube coil hoop material assembly shrink coil hoop winding drum 402.

[0047] [Embodiment relating to synchronous control of the drawing drive drum of the cylindrical coil hoop material assembly in the tube shrinking device to which the cylindrical coil hoop material assembly is supplied] The primary winding and pulling-out drive drum 411, the secondary winding and pulling-out drive drum 421, the tertiary winding and pulling-out drive drum 431, and the quaternary winding and pulling-out drive drum 441 (D4) are driven to rotate in a synchronized manner. The synchronized rotational operation control of the primary winding and pulling-out drive drum 411, the secondary winding and pulling-out drive drum 421, the tertiary winding and pulling-out drive drum 431, and the quaternary winding and pulling-out drive drum 441 (D4) is realized by the means, functions, and effects of the embodiment (A) or (B) below.

[0048] [(A) Implementation of Synchronous Control of Mechanical Synchronizing Mechanism of Each Winding / Pulling Drive Drum] When performing synchronization control mechanically (hardware), each control axis is implemented by a combination of a main shaft, gears, clutches, cams, etc. However, problems arise such as i) the machine itself becomes large, ii) wear of each part (main shaft, gears, etc.), iii) difficulty in designing and manufacturing complex cams, and iv) errors due to the precision of the hardware mechanism. These problems are solved by having the tube rotate around each of the drive drums, the primary winding and drawing out drive drum 411, the secondary winding and drawing out drive drum 421, the tertiary winding and drawing out drive drum 431, and the quaternary winding and drawing out drive drum 441 (D4), which has the effect of absorbing the error problems ii to iv, excluding i and iii, by the expansion and contraction of the length of the rotating tube. Although it depends on the material, diameter, and thickness of the tube to be contracted, it also changes depending on the material, diameter, thickness, and processing durability difference over time, depending on the integral of the size of each problem i to iv. At this time, the number of revolutions of the tube around each of the primary winding and pulling-out drive drum 411, secondary winding and pulling-out drive drum 421, tertiary winding and pulling-out drive drum 431, and quaternary winding and pulling-out drive drum 441 (D4) can be changed to one revolution, two revolutions, three revolutions, four-three revolutions, etc., for each drive drum separately or together for some of the revolutions, thereby absorbing errors due to the expansion and contraction of the total length of the tube as it turns, and achieving the effect of continuously maintaining processing while pulling.

[0049] [(B) Implementation of software-based synchronous control of each winding / pulling drive drum] To perform synchronous control of each winding and drawing out drive drum with software (user program), feedback information is obtained from an encoder attached to one of the main shafts, and positioning control is performed on the slave shafts other than the main shaft according to the current position. However, in the case of positioning control of three or more shafts, each shaft is moved to the target position in sequence, and in the case of a mechanism that operates in parallel such that control is started at the same time, an error occurs in the time until operation starts. This problem is solved by having the tube go around each of the drive drums, the primary winding and drawing out drive drum 411, the secondary winding and drawing out drive drum 421, the tertiary winding and drawing out drive drum 431, and the quaternary winding and drawing out drive drum 441 (D4), and the effect is achieved by absorbing the expansion and contraction of the length of the tube that goes around. By having the tube go around each drive drum, the effect is achieved of ensuring reliability redundancy. It depends on the material, diameter, and thickness of the tube to be contracted, but it also changes depending on the integral of the size of each issue and problem depending on the material, diameter, thickness, and processing durability difference over time of the tube. At this time, the number of revolutions of the tube around each of the primary winding and pulling out drive drum 411, secondary winding and pulling out drive drum 421, tertiary winding and pulling out drive drum 431, and quaternary winding and pulling out drive drum 441 (D4) can be changed to one revolution, two revolutions, three revolutions, four-three revolutions, etc., for each drive drum separately, or some of the revolutions can be performed together. This has the effect of absorbing errors caused by the expansion and contraction of the total length of the tube as it turns, and continuously maintaining processing while pulling the tube against the die.

[0050] <A tube coil hoop material assembly in a tube shrinking device to which the tube coil hoop material assembly is supplied, An embodiment relating to the synchronous control of the primary winding and drawing out drive drum 411, the secondary winding and drawing out drive drum 421, the tertiary winding and drawing out drive drum 431, and the quaternary winding and drawing out drive drum 441 (D4) by software> As an embodiment of the synchronization control by software for each winding pull-out drive drum, one of the primary winding pull-out drive drum 411, secondary winding pull-out drive drum 421, tertiary winding pull-out drive drum 431, and quaternary winding pull-out drive drum 441 (D4) is used as the main shaft, and the remaining are used as the slave shafts, with the main shaft drive motor and the main shaft interlocked and connected to a servo amplifier. In parallel with this, the slave shaft drive motor and the slave shaft are interlocked and connected to a servo amplifier. Signal information from the shaft drive motor is sent to the positioning controller (1) via the main shaft servo amplifier. (2) The positioning controller calculates the destination of the slave shaft with this information in the CPU unit (user program).

In Fig. 5, 501 is a large tube shrinking die, 502 is a medium tube shrinking die, 503 is a medium tube shrinking die, 509 is a small tube shrinking die, and 510 is a small tube shrinking die. The outer part of the tube reduction die is made of stainless steel, etc., and the inner wall of the tube reduction die is not explicitly shown because the figure is a schematic diagram, but the inner wall has a conical inner wall hole that is thick on the inlet side and thin on the outlet side. The vicinity where it comes into contact with the tube material is made of "single crystal diamond", which is the hardest material in the world because of its high precision, durability, and long life, or "sintered (polycrystalline) diamond", which is made by sintering diamond particles at high temperature and pressure, although of course ultra-hard materials can be used. In order to reduce friction between the die and the wire during processing, suppress wear of the die, and prevent seizure of the wire and surface scratches, dry lubricants, wet lubricants, and oil-based lubricants can be used depending on the finish state required for the tube material, but in the case of stainless steel tube material, oil-based lubricants are used as an embodiment due to their performance, function, and cost. In the case of processing stainless steel tube material that requires high-quality surface roughness, a single crystal diamond die is used as an embodiment.
