Description

Technical Field

[0001] The invention belongs to the technical field of processing equipment, in particular to an automatic production line for core tube flanging and copper foil buckling. Background Art

[0002] In mechanical equipment, cylindrical objects are often used as supports between two components. The two ends of the support column are usually welded between the two components. However, the short support column makes the gap between the two components small, which makes welding difficult. This process uses metal pipes as intermediate supports. In order to increase the strength of the metal pipe and the force-bearing area between the metal pipe and the two supporting components, it is usually necessary to perform a 90° flanging treatment on the end face of the pipe. In addition, this process eliminates the welding method and sets copper foil at the flanging. The copper foil is melted by high temperature and serves as a connecting medium. After cooling, the metal core pipe and the connecting component can be fixed.

[0003] The metal core tube cannot be flipped by hand, so the metal core tube needs to be flanging before the copper foil buckle operation. In the existing technology, the copper foil is fixed at the metal tube flange mostly by manually bending the copper foil and buckling it with the flanging, which has high labor costs and low production efficiency. Moreover, the way the copper foil is buckled on the flanging is not standard, which can easily cause the copper foil to fall out and the yield rate is low. In addition, after the flanging is completed, the core tube needs to be transferred to the copper foil buckle production line, which is very time-consuming for mass production and reduces production efficiency.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0045] Please refer to Figure 1-4 ;

[0046] The automatic production line of the present invention can perform multi-step operations such as punching, flanging, and fixing copper foil on core tubes, thereby reducing human intervention in the production process, reducing labor costs, and improving production efficiency. It specifically includes a conveying device 1 with several jigs, and an adaptive core tube placement device 2, a clamping device 3 that travels back and forth between the adaptive core tube placement device 2 and the conveying device 1, a lever-type punching device 4, a flanging device 5, a copper foil buckling device 6, and a blanking device 7 are sequentially installed along the running direction of the conveying device 1.

[0047] It should be noted that the gripping device 3 may be composed of a moving component and a plurality of air grippers, which is quite common in the field of automation and will not be described in detail here.

[0048] First, the storage device transports the core tube to the adaptive core tube placement device 2, and then the core tube is arranged by the adaptive core tube placement device 2, and the core tubes on the adaptive core tube placement device 2 are transferred to the jig by the clamping device 3. The jig is transported in sequence by the conveying device 1 to the lever punching device 4 for simultaneously punching holes at both ends of the core tube, the flanging device 5 for simultaneously flanging both ends of the core tube, and the copper foil buckle device 6 for bending the copper foil and fixing it on the flanging at both ends of the core tube. After completing the above process, the conveying device 1 sends the processed core tube to the unloading device 7, takes out the core tube on the jig, and then the unloaded jig enters the cycle and returns to the starting end of the conveying device 1;

[0049] The present invention can effectively solve the problem of improper manual operation when fixing copper foil through the copper foil buckle device 6, and the conveying device 1 integrates the various components to realize fully automated operation, which greatly improves production efficiency; in addition, the present invention also has a copper foil production function, and the copper sheet is punched by the punching device 8. A transfer device 9 is installed between the punching device 8 and the copper foil buckle device 6. The transfer device 9 can be extended into the punching device 8 to take out the copper foil and transfer it to the bottom of the copper foil buckle device 6 for easy acquisition; usually the copper foil is in the shape of a ring, and a bendable copper sheet is provided on the outer periphery of the copper foil. Based on its shape itself, it also needs to be placed neatly before it can be acquired by the copper foil buckle device 6. The transfer device 9 can solve the problem of copper foil placement very well, and at the same time, it can reduce the transportation and loading time of copper foil produced in other places, further improving production efficiency. The specific implementation method will be described in detail later.

[0050] One embodiment of the adaptive core barrel placement device 2 of the present invention is as follows: Figure 2 and Figure 3 ;

[0051] Before this, it should be noted that in order to improve production efficiency, several core tubes are usually processed at the same time. Since the core tube is cylindrical, in the prior art, a clamping method is usually adopted in the accumulator for loading. However, the premise of effective clamping is that the core tubes can be placed neatly, and gaps need to be reserved between adjacent core tubes to facilitate the insertion of the clamping device, which increases the difficulty of loading the core tubes. Alternatively, a single output core tube is used for loading in a manner similar to a vibrating plate, but this reduces the loading efficiency.

[0052] Specifically, it includes a feeding track 211, at both ends of which are a feeding port 212 and a discharging port 213. A supporting frame 221 is provided below the discharging port 213. In this embodiment, the feeding track 211 is tilted to facilitate the rolling of the core tube. In addition, in order to enable more accurate material unloading, the discharging port 213 can correspond to the several placement positions 222 on the supporting frame 221. For this reason, the feeding track 211 is bent twice to form a vertical downward discharging section so that the discharging port 213 faces downward; the lower end surface of the supporting frame 221 is slidably connected to the base 231, and the base 231 is equipped with a driving mechanism 232, which is connected to the supporting frame 221; in this embodiment, the driving mechanism 232 can be a combination of a driving motor and a screw pair;

[0053] During operation, the core tubes enter the feeding track 211 from the feeding port 212 in sequence, and then are guided by the feeding track 211 and output from the discharging port 213. At the same time, the driving mechanism 232 pushes the carrier 221 to slide toward the base 231, so that the several placement positions 222 on the carrier 221 correspond to the discharging port 213 one by one. When a core tube is output from the discharging port 213, one of the placement positions 222 on the carrier 221 corresponds to the discharging port 213, so that the core tube can accurately fall on the placement position 222. Then, under the push of the driving mechanism 232, the carrier 221 slides forward. , so that the adjacent placement positions 222 correspond to the discharge port 213, and then another core tube is output from the discharge port 213 and falls into the placement position 222. Similarly, after the placement positions 222 on the carrier 221 are full, the feeding track 211 no longer outputs core tubes, and the carrier 221, under the action of the pushing mechanism, makes several placement positions 222 completely misaligned with the discharge port 213. At this time, several core tubes have been arranged, and the adjacent placement positions 222 are independently spaced apart from each other, so that the clamping device 13 can extend between the adjacent core tubes, and can smoothly clamp the core tube and transfer it to the fixture;

[0054] The core tubes are output one by one through the feeding track 211, and the carrier 221 slides under the action of the driving mechanism 232. The placement positions 222 on the carrier 221 correspond to the discharge port 213 one by one, so that the core tubes can be placed neatly for easy loading. Secondly, the carrier 221 can place multiple core tubes, that is, multiple core tubes can be transferred to the jig at the same time, effectively improving the loading efficiency.

[0055] In this embodiment, a transport track 241 is connected to the feed port 212, and the transport track 241 serves as a conveying bridge between the storage device and the feed track 211. Preferably, the transport track 241 is arranged horizontally and is perpendicular to the feed track 211. The state of the core tubes on the transport track 241 is that two adjacent core tubes are connected head to tail to form a strip and are fed. When the core tubes correspond to the feed port 212, a single core tube can roll down from the feed track 211. It is further explained that since the transport track 241 and the feed track 211 are in a vertical state, the core tube cannot roll down when it reaches the position corresponding to the feed port 212. Therefore, a pushing mechanism for pushing the core tube into the feed track 211 is installed at the position of the transport track 241 corresponding to the feed port 212.

[0056] One embodiment of the pushing mechanism includes a cylinder 251, and the output end of the cylinder 251 is connected to a push plate 252. The push plate 252 moves toward the feed port 212 under the push of the cylinder 251. When the core tube is in the position of the transport track 241 close to the feed port 212, the push plate 252 is moved toward the feed port 212 by the cylinder 251, thereby pushing the core tube to move toward the feed port 212.

[0057] In addition, a pulley set 242 is provided around the bottom plate of the transport track, and the pulley set 242 is driven to move by a motor 243, so that the core tube can be pulled forward. That is, when a core tube is pushed into the feed port 212, there is a vacancy in the position of the transport track 241 corresponding to the feed port 212. Through the cooperation of the pulley set 242 and the motor 243, all the core tubes on the transport track 241 are pulled forward, so that the vacancy can be filled.

[0058] In this embodiment, the feeding track 211 is provided with a gate mechanism 26 at the outlet for controlling the output quantity of the core tubes. When the placement position 222 on the carrier 221 is full, the pushing mechanism will push the next core tube from the feeding port 212 into the feeding track 211. At this time, the discharge port 213 is closed by the gate mechanism 26 to prevent the core tubes from falling. Even if the pushing mechanism does not operate, the core tubes at the feeding port 212 may still fall. Therefore, it is necessary to provide the gate mechanism 26 at the discharge port 213.

[0059] More specifically, the gate mechanism 26 includes a cylinder 2 261 and a cylinder 3 262 symmetrically installed on both sides of the feeding track 211. The output ends of the cylinder 2 261 and the cylinder 3 262 are respectively connected to the gear rod 1 263 and the gear rod 2 264. When it is necessary to block the discharge port 213, the cylinder 2 261 and the cylinder 3 262 respectively push the gear rod 1 263 and the gear rod 2 264 into the feeding track 211 to block the core tube. After the core tube located on the placement position 222 is removed, the placement position 222 on the carrier 221 is driven by the pushing mechanism to correspond to the discharge port 213 again. At this time, the gear rod 1 263 and the gear rod 2 264 are respectively pulled out from the feeding track 211 by the cylinder 2 261 and the cylinder 3 262.

[0060] One embodiment of the lever punching device 4 of the present invention is described with reference to Figure 4 and Figure 5 ;

[0061] Using the principle of leverage to achieve the purpose of punching holes in products can effectively reduce the space occupied, simplify the structure, and enable the processing of multiple products at the same time, thereby improving work efficiency.

[0062] The two punching mechanisms 41 are slidably connected to the workbench or other fixed components. When the conveying device 1 transports the jig with the core tube to between the two punching mechanisms 41, the two punching mechanisms 41 are close to each other and fix the two ends of the core tube, and then start the punching operation. After completion, the two punching mechanisms 41 are in principle relative to each other, and the jig is transported to the next processing device through the conveying device 1. In this embodiment, the punching mechanism 41 specifically includes a mounting seat 411, and a rocker 412 rotatably connected to the mounting seat 411. One end of the rocker 412 is rotatably connected to the pushing mechanism 413, and the other end is rotatably connected to the mounting plate 414. In order to achieve up and down swinging of both ends of the rocker 412, it is foreseeable that the torso of the rocker 412 is rotatably connected to the mounting seat 411; during operation, the rocker 412 is pushed by the pushing mechanism 413. The mechanism 413 applies a thrust to the rocker arm 412, causing the end of the rocker arm 412 connected to the pushing mechanism 413 to move upward, while the end of the rocker arm 412 connected to the mounting plate 414 moves downward. While the mounting plate 414 moves downward, it drives several punching components 415 downward, so that the product can be punched. It is further explained that in order to prevent the mounting plate 414 from deflecting, the mounting plate 414 is slidably connected to the mounting seat 411, and can be specifically connected by a sliding pair. By adopting a sliding connection, the moving direction of the mounting plate 414 can be limited, that is, it can only move vertically. When the punching is completed, the pushing mechanism 413 drives the end of the rocker arm 412 to move downward, and the end of the rocker arm 412 close to the mounting plate 414 moves upward accordingly, so that the punching component 415 is separated from the product.

[0063] It should be noted that the present device can adopt a rotary hole or punching hole punching method. When the rotary hole method is used, a driving motor can be set up, and a driving wheel is provided at the output end of the driving motor. A plurality of driven wheels are installed on the mounting plate 414. The driven wheel and the driving wheel are connected by a belt drive, and a drill bit is provided at the center position of the driven wheel, so that multiple drill bits can be driven to work by one motor; if the punching hole method is used, the punching component 415 is a puncture needle, and the pushing mechanism 413 pushes the end of the rocker arm 412 to move upward, and at the same time, the other end of the rocker arm 412 will move downward, and the rocker arm 412 will apply a downward thrust to the mounting plate 414 to make it move downward. The thrust can also act on the puncture needle, causing the puncture needle to move downward so that the product can be punched into a hole.

[0064] In this embodiment, a fixing assembly for fixing the core tube is installed on the mounting seat 411 below the corresponding punching assembly 415. The fixing assembly is used to fix the product before punching to facilitate the punching operation.

[0065] The fixing assembly is a plurality of positioning posts 4161 fixed on the mounting seat 411. The positioning posts 4161 are placed horizontally and correspond to the punching assembly 415. When working, the positioning posts 4161 at both ends are pressed against the two ends of the core tube for fixing. A positioning block 4162 is fixed at the upper end of the positioning post 4161. The positioning block 4162 is provided with a positioning hole corresponding to the punching position. The positioning hole corresponds to the end of the punching assembly 415. For example, the punching assembly 415 is a puncture needle. When working, the puncture needle needs to pass through the positioning hole to contact the core tube. The positioning hole has a limiting and guiding function. If the position does not correspond, the puncture needle will touch other positions of the positioning block 4162 and cannot be further lowered, that is, it cannot contact the product, thereby ensuring the accuracy of the punching.

[0066] One embodiment of the flanging device 5 of the present invention;

[0067] Reference Figure 6 、 Figure 9 、 Figure 10 and Figure 11 The flanging device 5 of the present invention can realize flanging operations on both ends of the core tube at the same time, which can effectively improve production efficiency while meeting process requirements;

[0068] Specifically, it includes a second fixing base 51, on which two second flanging mechanisms 52 are symmetrically provided, that is, the two second flanging mechanisms 52 are symmetrically located on both sides of the conveying device 1, and the second flanging mechanisms 52 are used to form 90° flanging. The second flanging mechanisms 52 are described in detail below, including a second driving assembly 521 symmetrically installed on the second fixing base 51, and a second stamping assembly 522 is installed at the output end of the second driving assembly 521. The two stamping assemblies are symmetrically arranged, and a clamping mechanism 53 for fixing the shape of the metal core tube is also installed between the two stamping assemblies 522;

[0069] One embodiment of the clamping mechanism 53 in the present invention includes an upper mold 531 and a lower mold 532 used in conjunction with each other, the lower mold 532 is provided with a plurality of first clamping positions 533, and the upper mold 531 is provided with a plurality of second clamping positions 534. The shape of the combination of the first clamping position 533 and the second clamping position 534 is adapted to the shape of the outer peripheral wall of the core tube, so as to clamp the core tube. The upper mold 531 is connected to a driving component 3 535, and the lower mold 532 is connected to a driving component 4 536. During operation, the conveying device 1 drives the jig to be located between the two stamping components 2 522, and then drives the upper mold 531 and the lower mold 532 to close the mold to clamp the core tube through the driving component 3 535 and the driving component 4 536 to prevent the core tube from being deformed by the extrusion flanging. At this time, the connecting section of the core tube still partially protrudes from the clamping mechanism 53 to form the flanging.

[0070] After that, the two second driving assemblies 521 are started, driving the two second punching assemblies 522 to approach each other, that is, the second punching assemblies 522 are close to the two ends of the core tube respectively. When the two second punching assemblies 522 move to a certain position, they abut against the side of the clamping mechanism 53, and at the same time, the protruding part of the core tube and the clamping mechanism 53 are bent, and the flanges at both ends are pressed against the side of the clamping mechanism 53 by the second punching assemblies 522 respectively. After being bent, the flanges form a right angle, and finally the flanges form a 90° angle.

[0071] Furthermore, before forming the 90° flange, the aperture of the core tube end can be enlarged to avoid cracks in the flange during one-time forming. Therefore, two flange mechanisms 55 symmetrically installed on both sides of the conveying device 1 are provided before the flange mechanism 52. Figure 6-Figure 8, specifically including two driving components 551 symmetrically mounted on a fixed seat 54, a stamping component 552 is installed at the output end of the driving component 551, the stamping component 552 includes a fixed plate 5221, and a plurality of punches 5222 are installed on the fixed plate 5221. The end face of the punch 5222 is provided with a conical surface. In this embodiment, the conical surface is 40°-50°, preferably 45°; when working, the conveying device 1 drives the jig to be located between the two stamping components 552, and then the two driving components 551 are started, driving the two stamping components 552 to approach each other, that is, the two stamping components 552 approach the two ends of the core tube respectively, and simultaneously extrude to form flanging.

[0072] Of course, the structure of the second stamping component 522 can refer to that of the first stamping component 552 , the difference being that the plurality of punches 5222 on the second stamping component 522 are provided with 90° steps for bending and flanging.

[0073] The driving component 1 551 and the driving device used in this embodiment can be composed of multiple electric cylinders, which are symmetrically installed on the fixing seat 1 54 and the fixing seat 2 51, and connected to the stamping component 1 552 and the stamping component 2 522.

[0074] One embodiment of the copper foil buckle device 6 of the present invention is as follows: Figure 12 and Figure 13 ;

[0075] Specifically, it includes a moving mechanism 61, on which two turning mechanisms 62 are symmetrically provided, and each turning mechanism 62 is provided with at least one integrated bending fixture 63, wherein the number of the integrated bending fixtures 63 depends on the number of core tubes;

[0076] During operation, the transfer device 9 transports the copper foil to the bottom of the integrated bending fixture 63, and then the symmetrical flipping mechanism 62 acts at the same time to drive the integrated bending fixture 63 to flip so that its end face corresponds to the copper foil. After that, the moving mechanism 61 drives it up and down so that the integrated bending fixture 63 can obtain the copper foil and reset it. The flipping mechanism 62 is then used to drive the integrated bending fixture 63 to flip and reset. At this time, the moving mechanism 61 drives the integrated bending fixture 63 to approach the fixture so that the copper foil is close to the end face of the core tube. Finally, the copper foil is bent by the integrated bending fixture 63 so that the bent part of the copper foil can be buckled at the flange of the core tube, thereby completing the step of fixing the copper foil on the end face of the core tube. The realization of automated operation can ensure the bending standard of each copper foil and firmly fix it at the end of the core tube, which can save costs and improve the yield rate.

[0077] In this embodiment, the bending integrated fixture 63 includes a multi-claw cylinder 5 631, and the end face of the multi-claw cylinder 5 631 is provided with a profiling platform 632. It should be noted that the shape of the copper foil fastened to the end face of the core tube in the present invention is adapted to the shape of the flange, specifically in an annular shape, and a plurality of copper sheets that need to be bent are provided on the outer periphery of the annular shape; therefore, the shape of the profiling platform 632 is adapted to the hollow part of the copper foil. Of course, when the flange of the core tube is in other shapes, the shape of the copper foil will also change accordingly, and the shape of the profiling platform 632 will also change accordingly; a plurality of retractable marble assemblies 633 are evenly distributed on the peripheral wall of the profiling platform 632; when the profiling platform 632 is pressed into the hollow part of the copper foil, the inner periphery of the copper foil will be against the marble assembly 633, and the marble assembly 633 will be pressed. The ball assembly 633 is pushed into the profiling table 632. When the copper foil crosses over the ball assembly 633, the ball assembly 633 will extend out of the periphery of the profiling table 632 again and clamp the copper foil. Without external force, the copper foil cannot cross the ball assembly 633 and separate from the profiling table 632. Then, driven by the moving mechanism 61, the copper foil is made to cling to the flange of the core tube. Then, the multi-claw cylinder 5 631 drives the pressing block 634 to extend and contract to bend the copper sheet located on the outer periphery of the copper foil, so that the bent copper sheet is buckled into the flange of the core tube. At this time, the copper foil is fixed to the end of the core tube. Then, driven by the moving mechanism 61, the two integrated bending fixtures 63 are pulled out, so that the copper foil can cross the ball assembly 633 and separate from the profiling table 632.

[0078] It should be noted that a groove is provided on the pressing block 634, and the multi-claw cylinder 631 needs to act twice. The first time is to bend the copper sheet, and then the second time is to insert the bent part of the copper sheet into the groove for a second bending, so that the copper sheet fits with the other side of the flange to achieve buckling.

[0079] Reference Figure 14 The structure of the marble assembly 633 in this embodiment can be: a plurality of channels 6331 are provided in the profiling platform 632, a spring 6332 is provided in the channel 6331, and a marble body 6333 is provided at the end of the spring 6332. The diameter of the marble body 6333 is smaller than the orifice, so under the action of the spring 6332, part of the marble body 6333 can extend out of the orifice, and can retract into the channel 6331 when encountering external force. When the external force disappears, the marble extends out of the orifice again.

[0080] In this embodiment, the flipping mechanism 62 includes a mounting frame 621 and a flipping plate 622, wherein the mounting frame 621 is connected to the moving mechanism 61, and the flipping plate 622 is fixedly connected to the rotating shaft 623, the mounting frame 621 is rotatably connected to the rotating shaft 623, and a gear 624 is fixedly provided on the rotating shaft 623. The gear 624 is used in conjunction with a rack 625, and the rack 625 is connected to a push-pull cylinder four 626. The push-pull cylinder four 626 drives the rack 625 to move up and down, and synchronously drives the gear 624 to rotate the rotating shaft 623, and finally rotates the flipping plate 622. In this embodiment, the rotation angle of the flipping plate 622 is 90°.

[0081] Based on the above embodiment, one embodiment of the transfer device 9 is described below. Figure 15 ;

[0082] Specifically, it includes a mobile module 1 91 and a mobile module 2 92. The mobile module 1 91 is provided with a mobile plate 93. The mobile plate 93 is provided with a plurality of contour placement seats 94. The contour placement seats 94 are provided with slots adapted to the copper foil.

[0083] A movable frame 96 is mounted on the mobile module 2 92. The shape of the movable frame 96 is preferably "L"-shaped. The movable frame 96 can be extended into the punching device 8 and reciprocate between the punching device 8 and the profiling placement seat 94. A plurality of acquisition positions 97 are provided on the bottom surface of the movable frame 96. A plurality of suction cups 98 are provided on the acquisition positions 97. In this embodiment, the punching device 8 can simultaneously produce the same number of copper foils as the core tubes. Therefore, under the drive of the mobile module 2 92, the movable frame 96 is extended into the punching device 8, and a plurality of copper foils are obtained by using the suction cups 98 and then exit the punching device 8. At this time, it just corresponds to the plurality of profiling placement seats 94, and the plurality of copper foils are placed in the plurality of profiling placement seats 94 accordingly. Then, the plurality of profiling placement seats 94 are driven by the mobile module 1 91 to move to the bottom of the acquisition bending integrated fixture 63.

[0084] In addition, since a certain distance needs to be maintained between the plurality of integrated bending fixtures 63, the distance between the plurality of contour placement seats 94 also needs to be equal to the distance between them. In order to improve the utilization rate of the copper material, the distance between the copper foils formed at the punching device 8 will be relatively small, which will cause the distance between the plurality of copper foils to be unequal to the distance between the plurality of contour placement seats 94, resulting in the inability to transfer the copper foil. Therefore, the plurality of contour placement seats 94 are slidably connected to the movable plate 93, and a distance variable mechanism 95 is provided between the plurality of contour placement seats 94. The distance variable mechanism 95 can dynamically adjust the distance between the plurality of contour placement seats 94, thereby achieving the purpose of smoothly transferring the plurality of copper foils.

[0085] One embodiment of the pitch-changing mechanism 95 is described with the example of four contoured placement seats 94. Figure 16, specifically including connecting block 1 951a, connecting block 2 951b and connecting block 3 951c, one end of connecting block 1 951a is fixed on placement seat 1 952a, and the other end is provided with a bar hole 1 953a, and a stopper 1 954a is passed through the bar hole 1 953a, and the stopper 1 954a is connected to the placement seat 2 952b, one end of connecting block 2 951b is connected to the placement seat 2 952b, and the other end is provided with a bar hole 2 953b, and a stopper 2 954b is passed through the bar hole 2 953b, and the stopper 2 954b is connected to the placement seat 3 952c, one end of connecting block 3 951c is connected to the placement seat 3 952c, and the other end is provided with a bar hole 3 953c, and a stopper 3 954c is passed through the bar hole 3 953c, and the stopper 3 954c is connected to the placement seat 4 952d, and the placement seat 4 952d is connected to the regulating cylinder 6 955;

[0086] Under normal circumstances, the stopper 954a, the stopper 954b and the stopper 954c are located at the rightmost end of the strip hole 953a, the strip hole 953b and the strip hole 953c respectively. At this time, the distance between the placement seat 952a, the placement seat 952b, the placement seat 952c and the placement seat 4 952d is the smallest, which is convenient for the transfer assembly to place a number of copper foils. Then, by adjusting the cylinder 6 955, the placement seat 4 952d is pushed to the left. When the stopper 954c is located at the leftmost end of the strip hole 3 953c, the connection Block three 951c pulls the placement seat three 952c to move to the left, that is, the stop block two 954b moves to the left. When the stop block two 954b is located at the leftmost end of the bar hole two 953b, the placement seat two 952b is pulled to the left by the connecting block two 951b. When the stop block one 954a is located at the leftmost end of the bar hole one 953a, the spacing adjustment is completed. At this time, the spacing between the placement seat one 952a, the placement seat two 952b, the placement seat three 952c and the placement seat four 952d is the largest, corresponding to a number of obtaining bending integrated fixtures 63.
