Description

Technical Field

[0001] The invention relates to the technical field of pipe making, and in particular to a pipe making and cutting integrated machine and a method for producing pipe fittings. Background Art

[0002] There are two main types of pipe making machines: one is the common high-frequency pipe welding machine, and the other is the stainless steel pipe making machine. The high-frequency pipe welding machine is mainly used to produce various iron pipes, water pipes, etc.; while the stainless steel pipe making machine is mainly used to produce various stainless steel decorative pipes, such as: pipes for stair handrails, pipes for anti-theft doors and windows, pipes for stair handrails, guardrails, etc., and can also produce various automobile exhaust pipes, heat exchanger pipes, fluid pipes, food pipes, etc. Its processing technology is generally through uncoiling, forming, welding, grinding, sizing, straightening, sizing, cutting and other processes to produce shapes.

[0003] For example, Chinese Patent 201910352422.8 discloses a pipe making machine. Regardless of the solution recorded in the patent document or the technology currently on the market, the material is placed on a discharge rack and then a traction device is used to pull the material.

[0004] In the actual use of the pipe making machine using this method, the unloading rack is prone to excessive material release due to inertia, and the excessively released material is prone to knotting and bending. In order to solve this problem, brake pads are generally installed on the unloading rack to restrain this inertial rotation. However, the brake force is difficult to control after such a setting. In addition, as the material on the unloading rack decreases, the weight also changes. It is easy for the material to be pulled away during the traction process, resulting in the pipe making machine being unable to perform normal pipe making work. At the same time, it is also easy for the material to shift during the traction process, resulting in inaccurate welding of the weld, affecting the overall quality and production efficiency of the pipe fittings. Summary of the invention

[0005] The purpose of the present invention is to provide a pipe making and cutting machine and a method for producing pipe fittings. The control system controls the rotation speed of the material rack mechanism by cooperating with the trigger component and the first sensor or the second sensor to ensure that the length of the temporarily stored material between the material rack mechanism and the first shaping device is always within the set range, thereby solving the problem in the prior art that the material cannot be pulled or the welding is offset, thereby affecting the overall production rate and quality of the pipe making machine.

At the same time, the driver 4 drives the slag suction pipe to rotate, so that the slag suction head rotates with the cutting point to perform rotary slag suction.

[0050] A method for producing pipe fittings, used in the pipe making and cutting integrated machine, comprising:

[0051] Step 1: Install the steel coil material on the material rack mechanism, and pull out the end of the steel coil, first pass through the trigger assembly, and then enter the first shaping device, welding device and adjustment traction device in sequence; the traction device starts to pull the clamped pipe to move;

[0052] When the trigger component triggers the first sensor, it means that the length of the temporarily stored material has fallen below the minimum preset value. At this time, the control system controls the material rack mechanism to speed up the rotation speed to speed up the release of the material.

[0053] When the trigger component triggers the second sensor, it means that the length of the temporarily stored material has exceeded the maximum preset value. At this time, the control system controls the material rack mechanism to slow down the rotation speed and reduce the release speed;

[0054] Step 2: The first shaping device performs preliminary shaping on the sheet material, so that the sheet material is bent toward the middle at both ends along the width direction to form a tubular material, and welds are formed at both ends;

[0055] Step 3: The weld seam capturing mechanism of the welding device captures the weld seam, so that the welding head tracks the weld seam for welding;

[0056] Step 4: After welding is completed, the pipe is conveyed to the rotary cutting device after passing through the traction device; when the pipe entering the rotary cutting device reaches the set length, the cutting mechanism performs rotary cutting on the pipe;

[0057] During the cutting process, the work surface moves synchronously with the pipe;

[0058] Step 5: The slag suction head of the slag suction device extends into the area to be cut, and follows the cutting point to suck the slag;

[0059] During the cutting process, the slag suction head rotates along with the cutting point;

[0060] Step 6: After the cutting is completed, the push-pull member pulls the slag suction head out of the pipe, the clamping device is released, and the cut pipe slides into the collection area along the receiving device;

[0061] The work surface 3 moves back to the initial position, and the above steps 4, 5 and 6 are repeated.

[0062] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0063] 1. The design of the present invention is to design the material rack mechanism to be able to drive the steel coil material to rotate. The control system controls the rotation speed of the material rack mechanism by cooperating with the trigger component and the first sensor or the second sensor to ensure that the length of the temporarily stored material between the material rack mechanism and the first shaping device is always within the set value, so as to solve the problem in the prior art that the material cannot be pulled immobile, or during the pulling process, the material is offset due to the material rack constrained by the brake pad, resulting in inaccurate welding of the weld, affecting the production quality of the pipe fittings and the production efficiency of the equipment.

[0064] 2. The guide frame of the present invention can constrain the trigger assembly so that it can accurately cooperate with the first sensor and the second sensor. At the same time, the counterweight is set to stretch the material downward on the one hand, so that the material can overcome its own elasticity and unfold as flat as possible, thereby ensuring the accurate measurement of the temporarily stored material; on the other hand, it can give the material a downward force so that the material can fit tightly against the bottom of the shaping device, thereby ensuring the accuracy of the position of the weld after shaping, ensuring the accuracy and efficiency of subsequent welding, and ensuring the quality of pipe making.

[0065] 3. The welding device of the present invention captures the weld by means of a weld capture mechanism, and then adjusts the position of the laser welding mechanism in real time, thereby ensuring welding accuracy and welding quality, and avoiding welding leaks or unstable welding.

[0066] 4. The rotary cutting device of the present invention is installed on a work surface, and the control system drives the work surface to move through the driving mechanism 3, so that the moving speed of the work surface is the same as the welding speed of the pipe fittings, thereby achieving cutting of the welded pipe fittings under continuous welding, so that the pipe making machine can achieve uninterrupted production of pipe fittings of specific specifications, making the pipe making machine more efficient as a whole and having better welding quality.

[0067] 5. The clamping device of the present invention can clamp the pipe after passing through the rotary cutting device, and then cut it. This can restrain the end of the pipe and avoid shaking of the end of the pipe, thereby ensuring the cutting accuracy and the flatness of the cutting plane.

[0068] 6. The slag suction device of the present invention realizes the rotation of the slag suction pipe and the slag suction head through the driver 4. When the push-pull member extends the slag suction head and the slag suction pipe into the cutting position in the pipe fitting, it can rotate synchronously with the cutting point and suck the slag with the cutting point, thus ensuring the slag suction effect;

[0069] At the same time, under the action of driver three, the fixed plate can move in the radial direction relative to the forward direction of the pipe fitting, so that the pipe fitting can be avoided and the pipe fitting can be extended to a longer length, so that the pipe making machine has the ability to cut long pipes, thereby improving the applicability and practicality of the pipe making machine itself.

[0094] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0095] like Figure 1 As shown, a pipe making and cutting integrated machine comprises a frame 1, on which a material placing device 100 for placing sheet materials, a first shaping device 200 for shaping the materials into a tube, a welding device 300 for welding the weld of the tubular material, a traction device 400 for providing movement of the material in the machine, a rotary cutting device 500 for cutting the tubular material into pipe fittings of a set length, and a material receiving device 600 for centrally collecting the cut pipe fittings are provided, and a control system 2 capable of coordinating the work between the various devices is also provided;

[0096] The control system 2 is programmed according to requirements, and those skilled in the art can program it according to actual conditions, so a detailed description is omitted.

[0097] In the above-mentioned device, except for the control system 2, other devices are arranged in sequence according to the processing order, so that the sheet material can be produced into a pipe of a set length, and the pipe can be used to make a thermos flask liner or other items.

[0098] like Figure 1 and Figure 2 As shown, the material discharging device 100 mainly includes a material rack mechanism 101 and a material control mechanism 102;

[0099] The material rack mechanism 101 is mainly used for placing steel coil materials, and includes a base 108 and a rotating disk 109. The rotating disk 109 is rotatably arranged on the base 108. A driver 110 is arranged on the base 108. The driver 110 is connected to the rotating disk 109, so as to drive the rotating disk 109 to rotate. The driver 110 can adopt a servo motor or a motor, and a reducer can be used to assist the rotation connection between the driver 110 and the rotating disk 109.

[0100] The reducer can increase the torque of the driver 110 and reduce the rotation speed, so as to drive the rotation of the rotating disk 109 at a lower speed, that is, control the release speed of the material.

[0101] The material control mechanism 102 is mainly used to control the rotation speed of the driver 110, thereby adjusting the material release speed.

[0102] Steel coil materials are mainly made of sheet materials with a certain width and unlimited length, which are rotated into a disc.

[0103] The specific plan is as follows:

[0104] The material control mechanism 102 mainly includes a guide frame 106, a trigger assembly 105, a first sensor 103 and a second sensor 104;

[0105] The guide frame 106 is installed between the material frame mechanism 101 and the first shaping device 200, that is, a fixed rod 111 protrudes from the frame 1, and the guide frame 106 is installed on the end of the fixed rod 111. The first sensor 103 and the second sensor 104 are installed on the upper and lower ends of a vertical support rod 112 of the guide frame 106, and the end of the trigger component 105 is passed through the support rod 112 and installed between the first sensor 103 and the second sensor 104, and can move up and down between the first sensor 103 and the second sensor 104; the trigger component 105 can be supported by the passing material and move up and down with the tension of the sheet material.

[0106] The mounting structure of the trigger assembly 105 and the support rod 112 is as follows;

[0107] It comprises two guide blocks 113 sleeved on different support rods 112 , and the two guide blocks 113 are connected by a cross bar.

[0108] The material mainly passes through the cross bar, thereby supporting the trigger assembly 105, and then enters the first shaping device 200. As the welding operation proceeds, the length of the temporarily stored material between the material rack mechanism 101 and the first shaping device 200 is gradually shortened, thereby pulling the trigger assembly 105 upward and placing it between the first sensor 103 and the second sensor 104.

[0109] The control principle is as follows:

[0110] When the trigger assembly 105 is pulled up to the first sensor 103 at the upper end, the guide block 113 triggers the first sensor 103, and the control system 2 receives the signal from the first sensor 103, indicating that the temporarily stored material is shorter and has fallen below the set value. At this time, the control system 2 will control the driver 110 to increase the rotation speed, thereby accelerating the rotation speed of the rotating disk 109, increasing the release speed of the material, and causing the trigger assembly 105 to drop away from the first sensor 103;

[0111] When the temporarily stored material is too long, the guide block 113 will move down to the second sensor 104, triggering the second sensor 104. At this time, the control system 2 will control the driver 110 to reduce the rotation speed, thereby slowing down the rotation speed of the rotating disk 109, reducing the release speed of the material, and causing the trigger component 105 to rise and fall away from the second sensor 104.

[0112] The ideal state is that the trigger component 105 is located in the middle of the distance between the first sensor 103 and the second sensor 104, and at this time the length of the temporarily stored material is most suitable.

[0113] The design of the present invention is to design the material rack mechanism 101 to be able to drive the steel coil material to rotate. The control system 2 controls the rotation speed of the material rack mechanism 101 through the cooperation of the trigger component 105 with the first sensor 103 or the second sensor 104 to ensure that the length of the temporarily stored material between the material rack mechanism 101 and the first shaping device 200 is always within the set value, thereby solving the problem of the prior art that the material cannot be pulled still, or the material is offset due to the constraint of the brake pad during the pulling process, resulting in inaccurate welding of the weld, affecting the production quality of the pipe fittings and the production efficiency of the equipment.

[0114] At the same time, as the welding operation proceeds, the steel coil material on the material rack mechanism 101 gradually decreases, and the radius of the steel coil also gradually decreases. Only by changing the rotation speed can the accurate use of the material be guaranteed; the material control mechanism 102 of this solution can perfectly solve this problem, and can be adjusted in real time according to actual conditions, making it more convenient and more accurate to use.

[0115] In the prior art, a sufficient distance between the first shaping device 200 and the discharging device 100 is required to meet the normal production of the equipment, which results in a large area occupied and causes waste.

[0116] The design of the present invention can shorten the spacing requirement between the first shaping device 200 and the discharging device 100 as much as possible, reduce the floor space, avoid waste of space and site expenses, and reduce costs.

[0117] like Figure 2As shown, in order to further ensure the length control of the temporarily stored material, a counterweight 107 is installed on the trigger assembly 105. The counterweight 107 can be a simple metal block installed on the cross bar; or it can be a metal roller, and the two ends of the metal roller are respectively installed on the guide block 113. The metal roller is placed above the guide block 113, and the material passes between the metal roller and the cross beam, and the metal roller can roll on the upper end surface of the material.

[0118] On one hand, the counterweight 107 can stretch the material downward so that the material can overcome its own elasticity and spread out as flatly as possible, thereby ensuring accurate measurement of the temporarily stored material; on the other hand, it can give the material a downward force so that the material can cling to the bottom of the shaping device, thereby ensuring the accuracy of the position of the weld after shaping, ensuring that subsequent welding is carried out accurately and efficiently, and ensuring the quality of pipe making.

[0119] The counterweight 107 is designed to look like a metal drum, which can eliminate the obstruction of the counterweight 107 to the movement of materials as much as possible. At the same time, the rolling friction wear is smaller, which can ensure the service life of the counterweight 107.

[0120] like Figure 3 As shown, the structure of the first shaping device 200 is as follows.

[0121] The first shaping device 200 includes a plurality of shaping plates 201 , each of which is provided with a shaping hole 202 with different apertures.

[0122] Two movable grooves are provided on the frame 1, and the shaping plate 201 is installed on the frame 1 by the cooperation of bolts and the movable grooves. Meanwhile, the shaping plate 201 can move in the movable grooves, thereby adjusting the spacing between the shaping plates 201 to meet processing requirements.

[0123] The shaping plates 201 are arranged in sequence according to the size of the forming holes 202, that is, arranged from large to small. The material enters from the largest forming hole 202 and extends from the smallest forming hole 202. As the forming holes 202 gradually shrink, the sheet material can be rolled into a tube step by step, and then the tubular material enters the welding device 300 for welding of the weld.

[0124] In the process of passing through the forming holes 202 in sequence, the sheet material is bent toward the middle at both ends along the width direction to form a tubular material, and welds are formed at both ends.

[0125] A guiding and positioning mechanism 203 is arranged on the outside of the largest forming hole 202. The guiding and positioning mechanism 203 includes a transverse plate and two positioning rods. The positioning rods are respectively installed at both ends of the transverse plate. The spacing between the positioning rods is slightly larger than the width of the material, so that the material is constrained between the positioning rods, so that the material can enter the largest forming hole 202 more accurately and horizontally.

[0126] This arrangement ensures that the shaping is accurate, so that the weld of the pipe after shaping is always facing upward, which is convenient for subsequent processing and ensures processing quality.

[0127] like Figure 3 As shown, a press seam mechanism 204 is installed between the shaping plate 201 of the smallest forming hole 202 and the welding device 300 , and the press seam mechanism 204 includes a press seam seat 205 , an adjusting screw rod 206 and a press block 207 .

[0128] The adjusting screw rod 206 is threadedly connected to the upper end of the seam pressing seat 205 , and a handle is installed on the upper end of the adjusting screw rod 206 .

[0129] The pressing block 207 is movably placed in the pressing seat 205 and connected to the adjusting screw 206. By rotating the adjusting screw 206 with a handle, the pressing block 207 can be driven to move up and down. A pressing wheel 208 is provided at the lower end of the pressing block 207, and the pressing wheel 208 presses against the weld of the pipe fitting.

[0130] By adjusting the upper and lower positions of the press wheel 208, the weld is rolled and the edge of the weld is rolled to be more rounded, thereby ensuring the aesthetics and roundness of the pipe after subsequent welding, and the pipe is more in line with the standard.

[0131] like Figure 4 As shown, the structure of the welding device 300 is as follows:

[0132] The welding device 300 includes a first adjustment mechanism 303, a laser welding mechanism 301 for welding a weld seam, and a weld seam capturing mechanism 302 for capturing the weld seam;

[0133] The first adjusting mechanism 303 is installed on the frame 1, and the first adjusting mechanism 303 mainly includes a first screw assembly 304 and a second screw assembly 305; the first screw assembly 304 is horizontally arranged on the frame 1, that is, above the pipe fitting, for adjustment in the horizontal direction; a fixed plate 1 is arranged on the first screw assembly 304, and drives the fixed plate 1 to move horizontally; a fixed plate 2 is hinged on the fixed plate 1, and the inclination angle of the fixed plate 2 can be adjusted, the second screw assembly 305 is installed on the fixed plate 2, and a fixed plate 901 3 is installed on the second screw assembly 305, and the second screw assembly 305 drives the fixed plate 901 3 to move up and down, the laser welding mechanism 301 is installed on the fixed plate 901 3, and the weld capture mechanism 302 is installed on the laser welding mechanism 301.

[0134] The second screw rod assembly 305 is mainly used to adjust the vertical position. The vertical expression does not only represent the vertical direction, but also can be an inclination relative to the vertical direction.

[0135] The laser welding mechanism 301 adopts the laser welding technology available on the market, which will not be described in detail;

[0136] The weld capture mechanism 302 mainly captures the weld through a camera, and the control system 2 adjusts the first screw assembly 304 and the second screw assembly 305 accordingly based on the captured situation, thereby adjusting the position relationship and distance between the laser welding mechanism 301 and the weld, thereby ensuring that the laser welding mechanism 301 can track the weld in real time for welding.

[0137] Because in the actual shaping process, the weld is not always in the same straight line and may be offset. This device can solve this problem well and ensure welding.

[0138] The control system 2 captures the signal of the weld through the weld capture mechanism 302, and adjusts the position of the laser welding mechanism 301 in real time through the first screw assembly 304 and the second screw assembly 305, so that the laser welding mechanism 301 can accurately weld the weld.

[0139] Ensure welding accuracy and quality, avoid welding leakage or unstable welding, and make the welding marks flatter and smoother.

[0140] Traditional welding uses tungsten needles, which are worn out during the welding process. After long-term use, the wear of the tungsten needles will cause uneven welding marks or even welding leaks, resulting in a decline in the overall quality of the pipe fittings and affecting the production of subsequent products.

[0141] The distance from the center point of the capture image of the weld capture mechanism 302 to the welding point of the laser welding mechanism 301 is less than 15 mm, and can be maintained at 1 mm according to actual conditions.

[0142] This can ensure that there will be no errors in cold wind tracking and welding, that is, avoid the situation where the weld tracking is accurate but the welding position is wrong due to a large interval, thereby ensuring the welding quality.

[0143] A detector can be installed on the frame 1, mainly used to detect the moving speed and length of the pipe in the equipment, so as to facilitate the control system 2 to coordinate the efficiency between various devices to ensure the normal and accurate pipe making and cutting.

[0144] like Figure 5 As shown, a cooling device 4 is installed on the frame 1. The cooling device 4 is installed after the welding device 300. That is, after the pipe is welded, it will enter the cooling device 4 for cooling.

[0145] The cooling device 4 is installed above the welding mark, mainly to cool the welding position and remove impurities on the welding mark.

[0146] The cooling device 4 includes two connecting arms 41. A fixing chuck is provided at the lower end of the connecting arm 41. A cooling block 42 is installed on the fixing chuck. The cooling block 42 is connected to a coolant. The coolant mechanism is a common design now and will not be described in detail.

[0147] The cooling block 42 is designed to be arc-shaped, and the pipe fittings pass through the arc-shaped groove at the lower end of the cooling block 42 and are cooled while passing through to avoid thermal deformation of the pipe fittings.

[0148] At the same time, a rolling wheel 43 is arranged between the cooling block 42 and the welding device 300. The rolling wheel 43 rolls on the weld mark. During the rolling process, on the one hand, the shape of the weld mark can be integrated; on the other hand, the residual impurities on the weld mark can be removed and the impurities can be made to slide into the collection box below, which can be subsequently processed in a centralized manner, which is simple and convenient.

[0149] like Figure 5 and Figure 6 As shown, the structure of the traction device 400 is as follows.

[0150] The traction device 400 includes an upper mold mechanism 401, a lower mold mechanism 402, a driving mechanism 1 403 and a second adjustment mechanism 404;

[0151] A first fixed frame is installed on the frame 1, and the upper mold mechanism 401 and the lower mold mechanism 402 are installed in the middle of the first fixed frame 405; the driving mechanism 403 is mainly used to drive the upper mold mechanism 401 and the lower mold mechanism 402 to rotate; the second adjustment mechanism 404 is mainly used to adjust the distance between the upper mold mechanism 401 and the lower mold mechanism 402.

[0152] A clamping groove 1 406 is formed on the upper mold mechanism 401 , and a clamping groove 2 407 is formed on the lower mold mechanism 402 . The clamping groove 1 406 and the clamping groove 2 407 cooperate to form a clamping cavity 408 .

[0153] When the pipe is welded, it will enter the clamping cavity 408, which can clamp the pipe. With the drive of the driving mechanism 403, the clamped pipe can be continuously transported forward, pulling the subsequent pipe to move, thereby realizing the movement of the pipe in the machine.

[0154] The following is a detailed introduction to each institution.

[0155] First, the structures of the upper mold mechanism 401 and the lower mold mechanism 402 are the same. This embodiment is described by taking the upper mold mechanism 401 as an example.

[0156] The upper mold mechanism 401 includes two side plates 409, which are arranged in parallel. A driving shaft and a driven shaft are arranged between the side plates 409, and the two shafts are respectively fixed at two ends of the side plates 409. Two chains are sleeved on the driving shaft and the driven shaft, and each chain is close to the inner wall of one side plate 409. A plurality of upper modules 410 are arranged on the chains. The ends of the upper modules 410 are recessed inward to form a clamping groove 406, and the upper modules 410 can rotate with the chains.

[0157] A vertical rod is set on each of the four corners of the first fixed frame 405, and a sliding sleeve is set on the outer wall of both ends of the side plate 409. The sliding sleeve is set on the vertical rod, so that the upper mold mechanism 401 can move up and down along the axial direction of the vertical rod; the fixing method and structure of the lower mold mechanism 402 are the same as those of the upper mold mechanism 401, and can also move up and down.

[0158] The second adjustment mechanism 404 includes two screw rods 411, a hand wheel and a plurality of gears. The screw rods 411 are installed on both sides of the side plate 409 and are located in the middle of the first fixing frame 405. The upper and lower ends of the screw rods 411 are rotatably fixed on the first fixing frame 405. The hand wheel is installed in the middle of the upper end of the first fixing frame 405. The upper end of the screw rod 411 is provided with a gear. The lower end of the hand wheel is meshed with the gear provided on the upper end of the screw rod 411 through the gear. The hand wheel is rotated to drive the two screw rods 411 to rotate synchronously at the same time.

[0159] The upper and lower ends of the screw rod 411 are respectively formed with threaded segments, the threaded directions of the threaded segments are opposite, and the middle of the side plate 409 of the upper mold mechanism 401 and the middle of the side plate 409 of the lower mold mechanism 402 are both provided with a threaded sleeve, which is connected to the threaded sleeve respectively;

[0160] The hand wheel is turned to make the screw rod 411 rotate synchronously. Under the action of the threaded segment, the upper mold mechanism 401 and the lower mold mechanism 402 move toward the middle of the screw rod 411 or move away from the middle of the screw rod 411 at the same time, thereby forming a clamping or opening motion state.

[0161] The clamping state can be understood as the upper mold mechanism 401 and the lower mold mechanism 402 approaching each other, so that the clamping groove 1 406 and the clamping groove 2 407 cooperate with each other to form a clamping cavity 408 to clamp the welded pipe fitting and realize the traction movement of the pipe fitting.

[0162] The clamping cavity 408 can also play a role in shaping. The clamping cavity 408 is mainly cylindrical, which can better shape the overall shape.

[0163] The driving mechanism 1 403 is mainly used to drive the rotation of the chains in the upper mold mechanism 401 and the lower mold mechanism 402, so as to achieve the purpose of clamping and moving the pipe fitting.

[0164] The driving mechanism 403 mainly includes a driving motor 412 and a reducer 413. The driving shaft and the driven shaft of the upper mold mechanism 401 and the driving shaft and the driven shaft of the lower mold mechanism 402 are all extended out of the side plate 409. Gears are installed on the driving shafts. The gears of the two driving shafts are meshed with each other. At the same time, the driving shaft of the lower mold mechanism 402 is connected to the reducer 413 through a chain, so that the chain in the upper mold mechanism 401 and the chain in the lower mold mechanism 402 can rotate synchronously.

[0165] In order to ensure that the chain connecting the lower mold mechanism 402 and the reducer 413 is of appropriate tightness after the position of the lower mold mechanism 402 is moved, a movable plate 414 is installed on the frame 1, and a long adjustment groove is provided on the movable plate 414. A rotating wheel is installed at the front end of the movable plate 414 to support the chain. The fixed position of the movable plate 414 is adjusted by adjusting the position of the screw in the adjustment groove, thereby adjusting the tightness of the chain to ensure the stability of the chain connection between the reducer 413 and the lower mold mechanism 402.

[0166] The driving shaft and the driven shaft both extend out of the side plate 409 and are connected by a chain, which ensures that the driving force is uniform and the pipe can be moved stably and accurately.

[0167] like Figure 7 As shown, the frame 1 is also equipped with a second shaping device 700, which mainly includes two groups and has the same structure. The second shaping device 700 is mainly used to perform secondary shaping on the welded pipe fittings to further ensure the roundness and overall shape of the pipe fittings.

[0168] Taking one group as an example, the second shaping device 700 mainly includes a second fixing frame 701, two mounting plates 702, two shaping shafts 703 and a threaded shaft 704;

[0169] The second fixing frame 701 has four guide rods 705, and the four corners of the two mounting plates 702 are sleeved on the guide rods 705 and can move up and down on the guide rods 705;

[0170] A fixing sleeve is installed at the upper end of the second fixing frame 701, and the lower end of the threaded shaft 704 passes through the fixing sleeve, and the upper end is fixed on the fixing sleeve, so that the threaded shaft 704 is installed on the second fixing frame 701. The threaded shaft 704 can rotate on the second fixing frame 701, but cannot move up and down. At the same time, threads with opposite rotation directions are formed on the threaded shaft 704 at both ends, and the threads at both ends are respectively connected to the two mounting plates 702. The threaded shaft 704 is rotated to achieve the two mounting plates 702 to move closer and then away;

[0171] A shaping fixing seat is installed on the mounting plate 702, and the shaping shaft 703 is installed on the shaping fixing seat. A gap is left between the two shaping shafts 703, and this gap is used for the pipe fitting to pass through and perform shaping when passing through.

[0172] The gap between the shaping shafts 703 is adjusted by rotating the threaded shaft 704 to adjust the shaping effect.

[0173] The second shaping device 700 is mainly used to perform secondary shaping on the weld mark to avoid the problem of sharp angles at the weld mark.

[0174] like Figure 8 and Fig. 9 As shown, a guide rail 1 is arranged on the frame 1, and a work surface 3 is arranged on the frame 1. The work surface 3 is movablely arranged on the frame 1 through the cooperation of the guide rail 1 and the slider 1.

[0175] A driving mechanism 3 31 is installed on the lower end surface of the work table 3, and the driving mechanism 3 31 includes a servo motor 32 and a gear rack 33. The rack is installed on the frame 1, and the servo motor 32 is installed inverted on the work table 3. The gear is installed on the output end of the servo motor 32. The gear and the rack use helical teeth and are meshed with each other.

[0176] The servo motor 32 drives the gear to rotate and cooperates with the rack to realize the movement of the work table 3 on the frame 1.

[0177] The rotary cutting device 500 and the material receiving device 600 are both installed on the work surface 3. The measuring device is installed on the frame 1, which is mainly used to cooperate with the rotary cutting device 500 to calculate the length of the pipe entering the rotary cutting device 500, so as to send a signal to the control system 2. The control system 2 controls the driving mechanism 3 31 to work, so that the work surface 3 moves with the pipe to ensure synchronization, and then facilitate the implementation of cutting and other processes.

[0178] The measuring device mainly includes a displacement sensor and a corresponding mounting frame. The displacement sensor is installed on one side of the pipe through the mounting frame to perform laser ranging on the pipe. The control system 2 controls the operation of the corresponding device according to the measured distance, thereby realizing an integrated machine for pipe making and cutting.

[0179] like Figure 8 and Fig.10 As shown, the structure of the rotary cutting device 500 is as follows.

[0180] The rotary cutting device 500 includes a turntable mechanism 501, a cutting mechanism 502 and a second driving mechanism;

[0181] The turntable mechanism 501 includes a hollow rotating shaft 504, a turntable 1 505 is arranged at the end of the hollow rotating shaft 504, a driving mechanism 2 is mounted on the turntable 1 505, and a cutting mechanism 502 is mounted on the driving mechanism 2. The driving mechanism 2 is mainly used to fix the cutting mechanism 502 and adjust the position of the cutting mechanism 502. The cutting mechanism 502 avoids the through hole of the turntable 1 505, and the line of the cutting mechanism 502 can be wound in the outer groove of the turntable 1 505, so that the cutting mechanism 502 can rotate with the turntable 1 505.

[0182] A servo motor 506 is installed on the work table 3, and the servo motor 506 is connected to and drives the hollow rotating shaft 504 through a belt.

[0183] The through hole is coaxial with the previous clamping cavity 408 and the forming hole.

[0184] After the pipe is measured by the measuring device, it enters the through hole. When it enters the specified length, the control system 2 controls the work table 3 to move synchronously with the pipe at the same speed. At the same time, the servo motor 2 506 works to drive the turntable 1 505 to rotate, and the cutting mechanism 502 cuts and rotates around the pipe to perform rotational cutting on the pipe. During or before cutting, the driving mechanism 2 drives the cutting mechanism 502 to move to adjust the position of the driving mechanism 2 to ensure the accuracy of the cutting by the cutting mechanism 502.

[0185] The turntable 1 505 of the turntable mechanism 501 includes two turntables 507, which are connected by bolts or pins. After the connection, a gap is left between the turntables 507. This gap cooperates with the bolts or pins to realize the winding of the line of the cutting mechanism 502 on the turntable 1 505, thereby protecting the line and avoiding damage to the line.

[0186] One of the rotating plates 507 is mounted on the end surface of the hollow rotating shaft 504 and follows the rotation of the hollow rotating shaft 504 .

[0187] At the same time, such a design of the turntable can also reduce the weight as much as possible, realize the lightweight design of the device, save costs and reduce the compliance of the driving mechanism 331, so that the equipment has a longer service life and reduces the failure rate.

[0188] The above-mentioned driving mechanism 2 may adopt a third screw assembly 508 .

[0189] The cutting mechanism 502 includes a cutting head 509, and the cutting head 509 is a laser cutting head;

[0190] The third screw assembly 508 is installed at the edge of the turntable 1 505 . A bent plate 510 is provided on the third screw assembly 508 . The cutting head 509 is installed on the bent plate 510 . The design of the bent plate 510 enables the cutting head 509 to be perpendicular to the axis of the through hole.

[0191] This arrangement can ensure the cutting effect. At the same time, the arrangement of the third screw assembly 508 can adjust the position of the cutting head 509 to the pipe fitting, protecting the cutting head 509 from collision with the pipe fitting, and enabling the cutting head 509 to accurately cut the pipe fitting.

[0192] The cutting effect and cutting accuracy are greater than the existing designs.

[0193] A guide ring 511 is also installed on the work surface 3, which is located on one side of the hollow shaft 504. The axis of the guide ring 511 coincides with the axis of the through hole of the hollow shaft 504. The pipe is first extended into the guide ring 511 and then into the hollow shaft 504.

[0194] The guide ring 511 mainly guides the pipe into the hollow shaft 504. On the other hand, the through hole of the hollow shaft 504 is generally designed to be relatively large, and the guide ring 511 can be replaced to match the pipe, thereby ensuring the stability of the pipe and preventing the pipe from swinging in the through hole and affecting the cutting effect.

[0195] The line of the cutting mechanism 502 can be passed through a protective tube, and the protective tube can be a plastic threaded tube or a corrugated tube. This design can restrain the line to avoid entanglement, and at the same time protect the line to avoid wear. Secondly, the use of a corrugated tube or a threaded tube, its own characteristics will not affect the winding of the line on the turntable 505, and it is easier to use.

[0196] like Fig.11 As shown, a clamping device 800 is also installed on the work surface 3, which is mainly used to clamp the pipe to ensure cutting accuracy and cutting quality.

[0197] The material clamping device 800 includes a clamping frame 804, a second driver 801, a clamping arm assembly 1 802 and a clamping arm assembly 2 803;

[0198] The clamping frame 804 is installed on the work surface 3, and the end of the clamping frame 804 is placed above the pipe fitting. The clamping arm assembly 1 802 and the clamping arm assembly 2 803 are both movably installed at the end of the clamping frame 804. The driver 2 801 is installed at the end of the clamping frame 804, and is used to drive the clamping arm assembly 1 802 and the clamping arm assembly 2 803 to move relative to or toward each other, thereby clamping or releasing the pipe fitting.

[0199] Driver 2 801 may be a double-headed cylinder, and clamp arm assembly 1 802 and clamp arm assembly 2 803 are respectively installed at both ends of the double-headed cylinder, and the double-headed cylinder is used to drive clamp arm assembly 1 802 and clamp arm assembly 2 803 to clamp or open.

[0200] The structures of the clamp arm assembly 1 802 and the clamp arm assembly 2 803 are as follows.

[0201] Because the structures of the clamp arm assembly 1 802 and the clamp arm assembly 2 803 are the same, the clamp arm assembly 1 802 is used for deployment.

[0202] The clamping arm assembly 802 includes a horizontal arm 805 and at least two vertical arms 806. The horizontal arm 805 is connected to the driver 801. The vertical arms 806 are respectively installed at both ends of the horizontal arm 805, and the spacing between the vertical arms 806 can be adjusted. A clamping block 807 is installed at the lower end of the vertical arm 806. The side wall of the clamping block 807 is recessed inward to form a clamping groove 808 for clamping the pipe fitting.

[0203] When the pipe passes through a certain distance from the central axis, driver 2 801 drives clamp arm assembly 1 802 and clamp arm assembly 2 803 to move, and clamp the pipe through clamping groove 3 808. This can prevent the pipe from shaking and affecting the cutting effect. The guide ring 511 can further eliminate the shaking.

[0204] At the same time, after clamping the pipe, the noise caused by the vibration of the pipe can be eliminated, improving comfort.

[0205] The movable setting of the vertical arm 806 can adapt to cutting pipes of various lengths, thereby improving applicability.

[0206] The clamping block 807 can be made of rubber or plastic to avoid scratching the pipe.

[0207] At the same time, an induction switch 809 is installed on the clamping frame 804 to sense the end of the pipe. That is, when the end of the pipe triggers the induction switch 809, the control system 2 controls the driver to work and clamp the pipe. In conjunction with the measuring device described above, it can further ensure the measurement of the length of the pipe and ensure the cutting accuracy.

[0208] The length of the pipe to be cut can also be adjusted by adjusting the position of the induction switch 809 to achieve the purpose of adjustment.

[0209] Another embodiment of the clamping device 800 .

[0210] Driver 2 801 is not connected to clamp arm assembly 1 802 and clamp arm assembly 2 803. Instead, clamp arm assembly 1 802 and clamp arm assembly 2 803 are first installed on the slide rail, and then a rack is installed on clamp arm assembly 1 802 and clamp arm assembly 2 803 respectively. The driver adopts a motor, and a gear is installed on the output shaft of the motor. The gear engages with two racks at the same time, and the motor rotates, so that clamp arm assembly 1 802 and clamp arm assembly 2 803 move on the slide rail, thereby clamping or opening the pipe fitting.

[0211] like Fig.12 and Fig.13As shown, a slag suction device 900 is also installed on the work surface 3, and the slag suction device 900 is mainly used to absorb the residues generated during cutting.

[0212] The slag suction device 900 includes a fixed plate 901, a slag suction seat 902, a slag suction pipe 903, a pusher 907, a driver three 905 and a driver four 906;

[0213] The work surface 3 is provided with a second slide rail, which is perpendicular to the advancing direction of the pipe;

[0214] The fixed plate 901 is installed on the slide rail, and the driver 3 905 drives the fixed plate 901 to move horizontally on the work surface 3.

[0215] A push-pull device 907 is installed on the work surface 3. The push-pull device 907 can adopt a fourth screw rod assembly or a cylinder. In this embodiment, the fourth screw rod assembly is taken as an example. The slag suction seat 902 is installed on the fourth screw rod assembly. The fourth screw rod assembly can drive the slag suction seat 902 to move along the fourth screw rod assembly.

[0216] The rear end of the slag suction pipe 903 is arranged at the end of the fixed plate 901, and is equipped with a slag suction head 904, while the front end of the slag suction pipe 903 is rotatably arranged on the slag suction seat 902, and the rear end of the slag suction seat 902 is connected to a slag suction hose, and the slag suction hose is connected to a slag suction device, such as a vacuum pump, etc.;

[0217] The driver four 906 is installed on the slag suction seat 902, and the driver four 906 engages with the gear outside the front end of the slag suction tube 903 through the gear, and the driver four 906 drives the slag suction tube 903 to rotate, thereby performing rotary slag suction.

[0218] Furthermore, a sealing shaft 908 is installed at the front end of the slag suction pipe 903, a sealing ring 909 is installed on the outer wall of the sealing shaft 908, and the sealing shaft 908 is connected to the slag suction seat 902. The sealing ring 909 realizes the sealing between the sealing shaft 908 and the slag suction seat 902 without affecting the rotation of the slag suction pipe 903.

[0219] The slag suction device 900 works in conjunction with the rotary cutting device 500, and the specific working is as follows.

[0220] After the clamping device 800 clamps the pipe fitting, the pusher 907 pushes the slag suction seat 902 and the slag suction tube 903 to move, so that the rear end slag suction head 904 of the slag suction tube 903 extends into the pipe fitting until the cutting position, because the cutting head 509 is located directly above the pipe fitting, and the opening of the slag suction head 904 is also facing upward, so it can be guaranteed that cutting can start, and then the control system 2 controls the rotation speed of the turntable 505 and the rotation speed of the driver four 906, so that the opening of the slag suction head 904 can follow the rotation of the cutting head 509 in real time, thereby performing rotary cutting and slag suction, which can ensure the slag suction effect, avoid residual slag in the pipe fitting, and ensure neatness.

[0221] The movable arrangement of the fixed plate 901 is mainly for considering that when the pipe to be cut is long, the slag suction device 900 can be moved sideways to avoid the pipe, thereby achieving the cutting of the long pipe.

[0222] like Figure 8 As shown, the structure of the material receiving device 600 is as follows.

[0223] The material receiving device 600 includes a material receiving frame 601 and a material receiving assembly 602;

[0224] The receiving rack 601 is installed on the work surface 3 and is located below the clamping device 800; the receiving assembly 602 is placed on the side of the frame 1 and is mainly used to collect the cut pipes;

[0225] The upper end surface of the receiving frame 601 is inclined and covered with a buffer plate 603, which is used to buffer and reduce noise;

[0226] The buffer plate 603 may be made of a rubber plate or a polyurethane plate, or other materials.

[0227] After the pipe is cut, the falling pipe will first contact the buffer plate 603, which can buffer and absorb noise. Then, the pipe will roll along the upper end due to the tilt of the upper end until it falls into the receiving assembly 602, completing the collection of the pipe.

[0228] The material receiving assembly 602 is mainly a box frame 604, and a plurality of rubber strips 605 are fixed inside the box frame 604 to receive the pipe fittings and prevent the pipe fittings from being deformed due to collision.

[0229] The screw assembly described in the previous article is mainly a combination of a screw mechanism and a motor, which is realized by common technology and is widely used in the field of machine tools, so it will not be described in detail.

[0230] The method of using the pipe making and cutting integrated machine of the present application to produce pipe fittings is as follows;

[0231] Step 1:

[0232] The steel coil material is manually installed on the material rack mechanism 101, and the restraint of the steel coil material is released. The end of the steel coil is pulled out, first passes through the trigger assembly 105 and is placed in the first shaping device 200 for preliminary shaping. After shaping, the pipe passes through the welding device 300 and enters the traction device 400.

[0233] Step 2:

[0234] The traction device 400 is adjusted to clamp the material, and then the welding device 300 is adjusted so that the welding head of the welding device 300 can face the weld, and the weld capture mechanism 302 can accurately capture the weld.

[0235] Step 3:

[0236] The control system 2 controls the pipe making and cutting machine to make it work. The traction device 400 starts to pull the clamped pipe to move, and the welding device 300 welds the weld. During welding, the weld capture mechanism 302 captures the weld in real time. The control system 2 adjusts the welding points of the laser welding mechanism 301 in real time through the captured information to ensure the accuracy of the welding weld.

[0237] Step 4:

[0238] During the traction process, the length of the temporarily stored material between the material rack mechanism 101 and the first shaping device 200 is controlled to gradually decrease, so that the trigger assembly 105 moves on the guide frame 106;

[0239] When the trigger component 105 triggers the first sensor 103, it indicates that the length of the temporarily stored material has been lower than the minimum preset value. At this time, the control system 2 controls the material rack mechanism 101 to speed up the rotation speed to speed up the release of the material.

[0240] When the trigger component 105 triggers the second sensor 104, it indicates that the length of the temporarily stored material has exceeded the maximum preset value. At this time, the control system 2 controls the material rack mechanism 101 to slow down the rotation speed and reduce the release speed;

[0241] The control system 2 controls the rotation speed of the material rack mechanism 101 to ensure that the trigger component 105 is located between the first sensor 103 and the second sensor 104, and will not trigger the first sensor 103 and the second sensor 104, so as to control the length of the temporarily stored material and keep the length of the temporarily stored material within the set range, thereby facilitating the processing of subsequent processes and ensuring the processing accuracy.

[0242] Step 5:

[0243] After the welding is completed, the pipe fittings pass through the traction device 400 and are transported to the rotary cutting device 500. A detection device is set between the traction device 400 and the rotary cutting device 500 to detect the length of the pipe fittings transported to the rotary cutting device 500 and transmit the signal to the control system 2; when the pipe fittings entering the rotary cutting device 500 reach the set length, the control system 2 controls the driving mechanism 3 31 to work, so that the work table 3 moves synchronously with the pipe fittings. At the same time, a clamping device 800 is also installed on the work table 3 to clamp and fix the pipe fittings.

[0244] Step 6:

[0245] After the clamping device 800 clamps the pipe fitting, the slag suction device 900 is started, and the push-pull device 907 extends the slag suction head 904 to the place to be cut. Then the control system 2 controls the turntable mechanism 501 of the rotary cutting device 500 to rotate, and the cutting mechanism 502 performs rotary cutting on the pipe fitting. While cutting, the control system 2 also controls the driver four 906 to make the slag suction head 904 rotate following the cutting point, and follow the cutting point to suck the slag to ensure the slag suction effect.

[0246] Step 7:

[0247] After the cutting is completed, the push-pull device 907 pulls the slag suction head 904 out of the pipe, and the clamping device 800 is released. At the same time, the cut pipe slides into the collection area along the receiving device 600. At the same time, the control system 2 controls the driving mechanism three 31, so that the driving mechanism three 31 moves the work table 3 to the initial position, and repeats the above step four to cut the welded pipe.
