Description

Technical Field

[0001] This invention relates to the field of copper forming technology, and in particular to an automatic extrusion forming device for high-quality copper tubes. Background Technology

[0002] In the field of non-ferrous metal processing, copper is widely used in industries such as power, electronics, communications, aerospace, and sanitary ware due to its excellent electrical and thermal conductivity, ductility, and corrosion resistance. As industrial products develop towards miniaturization, precision, and high performance, the market is placing increasingly higher demands on the dimensional accuracy, surface quality, and internal density of copper parts. Extrusion molding, as a commonly used plastic processing technique, has become an important means of producing high-quality copper parts due to its advantages such as high material utilization, fast production efficiency, and effective improvement of the internal structure of materials.

[0003] Currently, most existing copper extrusion molding equipment uses traditional hydraulic or mechanical presses with simple fixed molds for single or limited-cycle molding. In practical production applications, this type of equipment suffers from several shortcomings: Firstly, molding accuracy and quality are difficult to guarantee. Traditional equipment typically completes molding through only one or two impacts during the extrusion process. For complex-shaped copper parts with high precision requirements, single-cycle molding makes it difficult to precisely control the uniform flow of material, easily leading to internal stress concentration, large dimensional deviations, and surface defects such as cracks or wrinkles, failing to meet the production standards for high-quality copper parts. Secondly, automation is low, resulting in poor material handling efficiency and safety. Most existing equipment relies on manual handling and positioning of copper parts. Manual operation is not only inefficient and unsuitable for large-scale automated production, but also poses safety hazards in high-temperature and high-pressure working environments. Furthermore, the accuracy of manual placement is unstable, easily leading to product scrap or mold damage due to positioning deviations. Thirdly, process integration is low, resulting in long production cycles. Traditional equipment typically separates the molding process from material conveying and unloading processes, requiring additional robotic arms or manual labor for transfer between different workstations. This not only increases the equipment footprint and manufacturing costs, but also prolongs the production cycle and reduces overall production efficiency. Especially in multi-pass continuous molding processes, workpieces need to be repeatedly transferred between multiple devices or stations, increasing the risk of positioning error accumulation. Furthermore, there is the risk of interference between the mold and the workpiece. In existing automation upgrade solutions, the pick-and-place mechanism, during vertical lifting or horizontal movement, often has a single motion trajectory, making it prone to interference with the forming mold or the main body of the equipment. This can lead to collision damage to the workpiece during pick-and-place, or cause equipment failure, affecting the stability and reliability of the production process. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention discloses a copper extrusion molding device with high-precision multi-pass sequential forming capability to optimize material flow and eliminate forming defects. It also integrates an efficient, stable, and safe automated pick-and-place and conveying mechanism, enabling fully automated operation of the entire process from loading, positioning, multi-pass forming to final unloading of copper parts, and effectively avoiding interference between components during movement. The technical solution adopted by this invention is: a high-quality copper tube automatic extrusion molding device, comprising a main frame and a forming mechanism for extruding copper parts. The main frame is equipped with a pick-and-place mechanism and an infeed mechanism for placing and removing copper parts.

[0005] Furthermore, the molding mechanism includes a clamping electric cylinder fixedly installed on the main frame, a clamping platform fixedly installed on the output end of the clamping electric cylinder, an inner mold fixedly installed on the clamping platform, a horizontal guide rail fixedly installed on the main frame, the clamping platform and the horizontal guide rail being slidably installed, and an outer mold being slidably installed on the main frame.

[0006] Furthermore, the molding mechanism also includes a molding electric cylinder fixedly installed on the main frame. A docking slide head is fixedly installed on the output end of the molding electric cylinder. A lower sliding block is slidably installed on the main frame. A movable slide is fixedly installed on the lower sliding block. Multiple molding tracks are fixedly installed on the movable slide. An inner push block is slidably installed on the molding track. The inner push block is provided with a groove that cooperates with the docking slide head. A molding head is fixedly installed on the inner push block.

[0007] After the copper part is placed between the outer and inner molds by the pick-and-place mechanism, the electric cylinder inside the main frame drives the outer mold to move slightly. At the same time, the clamping electric cylinder extends, causing the clamping table and the inner mold to slide along the horizontal guide rail, so that the inner and outer molds clamp and fix the copper part. The electric cylinder inside the main frame drives the movable slide and the lower sliding block to slide along the main frame, so that the first group of forming heads reaches both ends of the copper part. At this time, the docking slide head is located in the slide groove of the inner push block of the first group. At this time, the two forming electric cylinders extend, driving the inner push blocks and forming heads located at both ends of the copper part to slide along the forming rail. The forming cylinder moves inward, cold-pressing the copper part through the forming head. Then, the forming cylinder retracts, causing the forming head and the inner push block to return to their initial positions. Subsequently, the lower sliding block continues to slide, causing the second set of forming heads to reach both ends of the copper part. At this time, the docking slide head is located in the sliding groove of the inner push block of the second set. The forming cylinder extends, cold-pressing the copper part through the second set of forming heads. After the forming head and the inner push block return to their positions, the lower sliding block slides again. Multiple forming processes are achieved for the copper part through multiple sets of forming heads, finally obtaining the finished product. Then, the forming cylinder, the inner push block, and the forming head return to their initial positions.

[0008] Furthermore, the picking and placing mechanism includes a connecting frame fixedly installed on the main frame, a sliding box slidably installed on the connecting frame, a lead screw rotatably installed on the connecting frame, a square groove provided below the sliding box, an internal thread block slidably installed in the square groove below the sliding box, an internal thread block provided in the internal thread block, and the internal thread block and the lead screw form a threaded transmission.

[0009] Furthermore, the picking and placing mechanism also includes a square rotating shaft rotatably mounted on the connecting frame, an external transmission belt wrapped around the square rotating shaft and the lead screw, a lower limit plate fixedly mounted below the sliding box, and a sliding wheel slidably mounted on the square rotating shaft, the sliding wheel being located in the lower limit plate.

[0010] Furthermore, the picking and placing mechanism also includes a transfer motor fixedly installed inside the sliding box. A motor bevel gear is fixedly installed on the motor shaft of the transfer motor. Two rotating arms are rotatably installed on the sliding box. Side bevel gears are fixedly installed on the rotating arms and mesh with the motor bevel gears. Two inner rotating wheels are fixedly installed on the sliding box. A lower rotating arm is rotatably installed on the rotating arm. An outer rotating wheel is fixedly installed on the lower rotating arm. A rotating arm drive belt is wound around the outer rotating wheel and the inner rotating wheel.

[0011] Furthermore, the picking and placing mechanism also includes a clamping end fixedly installed at the bottom of the lower rotating arm, on which two clamping plates are slidably installed, and an electric cylinder for driving the clamping plates to slide is provided inside the clamping end.

[0012] Furthermore, the picking and placing mechanism also includes an inner drive wheel rotatably installed in the sliding box, a side bevel gear drives the inner drive wheel to rotate through an inner drive belt, and a vertical drive belt is wound around the inner drive wheel and the sliding wheel.

[0013] The electric cylinder inside the clamping end retracts, causing the clamping plate to move inward. At this time, the clamping plate above the feeding conveyor belt clamps the copper part to be processed on the conveyor belt, and at the same time, the clamping plate at the finished copper part clamps the finished copper part. Then, the clamping table retracts, causing the inner mold to move outward, and the outer mold to move outward a short distance at the same time, so that the inner mold and the outer mold are disengaged from the finished copper part. Then, the transfer motor starts to rotate, and the transfer motor drives the motor bevel gear to rotate. The motor bevel gear drives the side bevel gear and the rotating arm to rotate. When the rotating arm rotates, since the outer wheel rotates with the rotating arm, while the inner wheel does not rotate, a relative speed difference is generated between the outer wheel and the inner wheel. Through the rotating arm transmission belt, the outer wheel and the lower rotating arm rotate relative to the rotating arm, so that the lower rotating arm is always perpendicular to the ground, so that the lower rotating arm rises vertically. One set of clamping plates picks up the copper part on the feeding conveyor belt and lifts it up, and the other set of clamping plates picks up the finished copper part and lifts it up.

[0014] Simultaneously, the side bevel gear drives the inner drive wheel to rotate via the inner drive belt. The inner drive wheel drives the sliding wheel and the square shaft to rotate via the vertical drive belt. The square shaft drives the lead screw to rotate via the outer drive belt. The rotation of the lead screw causes the internal thread block to slide along the square groove at the bottom of the sliding box. During the initial movement of the internal thread block, the sliding box remains stationary because it is sliding within the square groove. This allows the copper part to rise vertically when lifted from the conveyor belt or between the inner and outer molds, preventing collisions with the forming head or main frame during lifting. Once the front end of the internal thread block contacts the sliding box, the internal thread block continues to move, causing the sliding box to slide along the connecting frame, thus realizing the rotation of the arm. While rotating, the sliding box moves laterally relative to the connecting frame. When the sliding box reaches its limit position, the copper part, which was originally above the feeding conveyor belt, is moved between the outer and inner molds. The copper part, which was originally in the processing position, is moved above the discharge conveyor belt. Then, the inner and outer molds clamp the copper part to be processed. After clamping, the clamping plate is released, and the conveyor belt sends out the processed copper part. Then, the transfer motor reverses, and the internal thread block slides in the square groove of the sliding box. At this time, the lower rotating arm and the clamping plate rise to prevent affecting the processing. After processing is completed, the transfer motor reverses, so that the two lower rotating arms return to the initial position for the next removal and placement of the copper part, and so on.

[0015] Furthermore, the inlet / outlet mechanism includes two conveyor frames fixedly installed on the main frame, each conveyor frame is equipped with a conveyor belt, and a motor for driving the conveyor belt to rotate is installed inside the conveyor frame. The two conveyor belts move in opposite directions.

[0016] The motor inside the conveyor frame drives the conveyor belt to rotate. One conveyor belt is used to feed the copper parts to be processed into the conveyor, and the other conveyor belt is used to send out the processed copper parts.

[0017] The beneficial effects of the present invention compared with the prior art are: (1) The present invention sets up a molding mechanism, a movable slide is slidably installed on the main frame, and multiple molding tracks, inner push blocks and molding heads are fixedly installed on the movable slide in sequence. When working, the lower sliding block can drive the movable slide to slide sequentially, so that the multiple molding heads reach the two ends of the copper part in a predetermined order, and are driven by the molding electric cylinder to perform multiple sequential cold pressing molding. This multi-stage progressive forming method can effectively disperse the deformation of a single forming, making the stress distribution of the copper material more uniform during plastic flow, avoiding defects such as internal cracks, surface wrinkles or dimensional deviations caused by a large deformation at one time, thereby improving the dimensional accuracy, surface smoothness and internal density of the copper parts, ensuring the production of high-quality copper parts; (2) Through the coordinated design of the transfer motor, bevel gear set, rotating arm, rotating arm transmission belt and screw transmission assembly in the pick-and-place mechanism, this invention realizes the compound linkage of vertical lifting and horizontal movement of the clamping end. When the transfer motor is driven, the lower rotating arm is kept perpendicular to the ground during the rotation process through the rotating arm transmission belt, realizing the stable vertical pick-and-place of the copper parts. At the same time, through the transmission of the inner transmission wheel, vertical transmission belt and screw, the sliding box is driven to slide horizontally, so that the equipment can simultaneously complete the clamping and lifting of the copper parts and the horizontal rotation. The entire set of actions of moving and lowering the placement can simultaneously complete the loading of unprocessed copper parts and the unloading of processed copper parts within one action cycle, shortening the production auxiliary time and improving the production cycle and automation level of the equipment; (3) The present invention realizes the delayed horizontal movement of the sliding box through the sliding fit structure of the internal thread block and the square groove at the bottom of the sliding box. At the initial stage of the transfer motor start-up, the internal thread block slides in the square groove first, and the sliding box remains stationary, so that the clamping end can rise vertically first and take the copper parts out smoothly from the conveyor belt or mold. After the internal thread block contacts the sliding box, the sliding box is driven to move horizontally, ensuring that the copper parts are first removed from the original work position and then transferred horizontally during the lifting process, effectively avoiding the collision between the copper parts and the forming head, mold or main frame caused by the simultaneous horizontal and vertical movement, ensuring the surface quality of the workpiece and the safety of the equipment operation.

Detailed Implementation

[0030] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] Example: Reference Figures 1-11 A high-quality copper tube automatic extrusion molding device includes a main frame 101 and a molding mechanism for molding copper parts 4. The main frame 101 is provided with a pick-and-place mechanism and an infeed mechanism for putting in and taking out copper parts 4.

[0032] like Figures 2-5As shown, the molding mechanism includes a clamping electric cylinder 102 fixedly installed on the main frame 101, a clamping platform 103 fixedly installed on the output end of the clamping electric cylinder 102, an inner mold 113 fixedly installed on the clamping platform 103, a horizontal guide rail 105 fixedly installed on the main frame 101, the clamping platform 103 and the horizontal guide rail 105 being slidably installed, and an outer mold 104 being slidably installed on the main frame 101.

[0033] like Figures 2-5 As shown, the molding mechanism also includes a molding electric cylinder 106 fixedly installed on the main frame 101. A docking slide head 107 is fixedly installed on the output end of the molding electric cylinder 106. A lower sliding block 109 is slidably installed on the main frame 101. A movable slide table 112 is fixedly installed on the lower sliding block 109. Multiple molding tracks 111 are fixedly installed on the movable slide table 112. An inner push block 108 is slidably installed on the molding track 111. The inner push block 108 is provided with a groove that cooperates with the docking slide head 107. A molding head 110 is fixedly installed on the inner push block 108.

[0034] After the copper part 4 is placed between the outer mold 104 and the inner mold 113 by the pick-and-place mechanism, the electric cylinder inside the main frame 101 drives the outer mold 104 to move slightly. At the same time, the clamping electric cylinder 102 extends, causing the clamping table 103 and the inner mold 113 to slide along the horizontal guide rail 105, so that the inner mold 113 and the outer mold 104 clamp and fix the copper part 4. The electric cylinder inside the main frame 101 drives the movable slide table 112 and the lower sliding block 109 to slide along the main frame 101, so that the first set of forming heads 110 reaches both ends of the copper part 4. At this time, the docking slide head 107 is located in the groove of the inner push block 108 of the first set. At this time, the two forming electric cylinders 106 extend, driving the inner push block 108 and the forming head 110 located at both ends of the copper part 4 to slide along the groove of the inner push block 108. The forming track 111 moves inward, and the copper part 4 is cold-pressed through the forming head 110. Then the forming electric cylinder 106 retracts, so that the forming head 110 and the inner push block 108 return to the initial position. Then the lower sliding block 109 continues to slide, so that the second set of forming heads 110 reaches both ends of the copper part 4. At this time, the docking slide head 107 is located in the sliding groove of the second set of inner push blocks 108. The forming electric cylinder 106 extends, and the copper part 4 is cold-pressed through the second set of forming heads 110. After the forming head 110 and the inner push block 108 return to their original positions, the lower sliding block 109 slides again. The copper part 4 is formed multiple times through the multiple sets of forming heads 110, and finally the finished product is obtained. Then the forming electric cylinder 106, the inner push block 108 and the forming head 110 return to the initial position.

[0035] like Figures 6-10As shown, the pick-and-place mechanism includes a connecting frame 201 fixedly installed on the main frame 101, a sliding box 202 slidably installed on the connecting frame 201, a lead screw 203 rotatably installed on the connecting frame 201, a square groove provided below the sliding box 202, an internal thread block 221 slidably installed in the square groove below the sliding box 202, an internal thread provided in the internal thread block 221, and the internal thread block 221 and the lead screw 203 form a threaded transmission.

[0036] like Figures 6-10 As shown, the pick-and-place mechanism also includes a square rotating shaft 205 rotatably mounted on the connecting frame 201. An external transmission belt 204 is wound around the square rotating shaft 205 and the lead screw 203. A lower limit plate 218 is fixedly installed below the sliding box 202. A sliding wheel 217 is slidably mounted on the square rotating shaft 205. The sliding wheel 217 is located in the lower limit plate 218.

[0037] like Figures 6-10 As shown, the pick-and-place mechanism also includes a transfer motor 206 fixedly installed in the sliding box 202. A motor bevel gear 207 is fixedly installed on the motor shaft of the transfer motor 206. Two rotating arms 208 are rotatably installed on the sliding box 202. A side bevel gear 209 is fixedly installed on the rotating arm 208. The side bevel gear 209 meshes with the motor bevel gear 207. Two inner rotating wheels 219 are fixedly installed on the sliding box 202. A lower rotating arm 211 is rotatably installed on the rotating arm 208. An outer rotating wheel 220 is fixedly installed on the lower rotating arm 211. A rotating arm drive belt 210 is wound around the outer rotating wheel 220 and the inner rotating wheel 219.

[0038] like Figures 6-10 As shown, the pick-and-place mechanism also includes a clamping end 212 fixedly installed at the bottom of the lower rotating arm 211. Two clamping plates 213 are slidably installed on the clamping end 212, and an electric cylinder for driving the clamping plates 213 to slide is provided inside the clamping end 212.

[0039] like Figures 6-10 As shown, the pick-and-place mechanism also includes an inner drive wheel 215 rotatably installed in the sliding box 202. A side bevel gear 209 drives the inner drive wheel 215 to rotate through the inner drive belt 214. The inner drive wheel 215 and the sliding wheel 217 are wrapped with a vertical drive belt 216.

[0040] The electric cylinder inside the clamping end 212 retracts, causing the clamping plate 213 to move inward. At this time, the clamping plate 213, located above the feeding conveyor belt 302, clamps the copper part 4 to be processed on the conveyor belt 302. Simultaneously, the processed copper part 4 is clamped at the location of the processed copper part 4. Then, the clamping table 103 retracts, causing the inner mold 113 to move outward. The outer mold 104 also moves outward a short distance at the same time, causing the inner mold 113 and the outer mold 104 to disengage from the processed copper part 4. Then, the transfer motor 206 starts to rotate, driving the motor bevel gear 207 to rotate. The motor bevel gear 207 drives the side bevel gear... When gear 209 and rotating arm 208 rotate, the outer rotating wheel 220 rotates along with the rotating arm 208, while the inner rotating wheel 219 does not rotate. At this time, the outer rotating wheel 220 and the inner rotating wheel 219 generate a relative speed difference. Through the rotating arm transmission belt 210, the outer rotating wheel 220 and the lower rotating arm 211 rotate relative to the rotating arm 208, so that the lower rotating arm 211 is always perpendicular to the ground, and the lower rotating arm 211 rises vertically. One set of clamping plates 213 picks up the copper part 4 located on the feeding conveyor belt 302 and lifts it up, and another set of clamping plates 213 picks up the processed copper part 4 and lifts it up.

[0041] Simultaneously, the side bevel gear 209 drives the inner drive wheel 215 to rotate via the inner drive belt 214. The inner drive wheel 215 drives the sliding wheel 217 and the square rotating shaft 205 to rotate via the vertical drive belt 216. The square rotating shaft 205 drives the lead screw 203 to rotate via the outer drive belt 204. The rotation of the lead screw 203 causes the inner thread block 221 to slide along the square groove at the bottom of the sliding box 202. For a short period before the inner thread block 221 moves, the sliding box 202 will not move because it is sliding in the square groove. This allows the copper part 4 to rise vertically when it is lifted from the conveyor belt 302 or between the inner mold 113 and the outer mold 104, preventing the copper part 4 from colliding with the forming head 110 or the main frame 101 during the lifting process. After the front end of the inner thread block 221 contacts the sliding box 202, the inner thread block 221 continues to move, driving the sliding box 202 along the connecting frame. 201 slides, allowing the rotating arm 208 to rotate while the sliding box 202 moves laterally relative to the connecting frame 201. When the sliding box 202 reaches its limit position, the copper part 4, which was originally above the feeding conveyor belt 302, is moved between the outer mold 104 and the inner mold 113. The copper part 4, which was originally in the processing position, is moved above the discharge conveyor belt 302. Then, the inner mold 113 and the outer mold 104 clamp the copper part 4 to be processed. After clamping, the clamping plate 213 is released, and the conveyor belt 302 sends out the processed copper part 4. Then, the transfer motor 206 reverses, and the internal thread block 221 slides in the square groove of the sliding box 202. At this time, the lower rotating arm 211 and the clamping plate 213 rise to prevent affecting the processing. After processing, the transfer motor 206 reverses, so that the two lower rotating arms 211 return to the initial position for the next removal and placement of the copper part 4, and so on.

[0042] When the sliding box 202 slides along the connecting frame 201, the lower limit plate 218 slides along the square rotating shaft 205 with the sliding wheel 217.

[0043] like Figure 11 As shown, the inlet and outlet mechanism includes two conveyor frames 301 fixedly installed on the main frame 101. A conveyor belt 302 is provided on the conveyor frame 301. A motor for driving the conveyor belt 302 to rotate is provided inside the conveyor frame 301. The two conveyor belts 302 move in opposite directions.

[0044] The motor inside the conveyor frame 301 drives the conveyor belt 302 to rotate. One conveyor belt 302 is used to feed the copper part 4 to be processed into the conveyor, and the other conveyor belt 302 is used to feed the processed copper part 4 out.

[0045] Working principle: The electric cylinder inside the clamping end 212 retracts, causing the clamping plate 213 to move inward. At this time, the clamping plate 213, located above the feeding conveyor belt 302, clamps the copper part 4 to be processed on the conveyor belt 302. Simultaneously, the processed copper part 4 is clamped at the location of the processed copper part 4. Then, the clamping table 103 retracts, causing the inner mold 113 to move outward. The outer mold 104 also moves outward a short distance at the same time, causing the inner mold 113 and the outer mold 104 to disengage from the processed copper part 4. Then, the transfer motor 206 starts to rotate, driving the motor bevel gear 207 to rotate. The motor bevel gear 207 carries... The moving bevel gear 209 and the rotating arm 208 rotate. When the rotating arm 208 rotates, the outer rotating wheel 220 rotates along with the rotating arm 208, while the inner rotating wheel 219 does not rotate. At this time, the outer rotating wheel 220 and the inner rotating wheel 219 generate a relative speed difference. Through the rotating arm transmission belt 210, the outer rotating wheel 220 and the lower rotating arm 211 rotate relative to the rotating arm 208, so that the lower rotating arm 211 is always perpendicular to the ground, so that the lower rotating arm 211 rises vertically. One set of clamping plates 213 picks up the copper part 4 located on the feeding conveyor belt 302 and lifts it up, and another set of clamping plates 213 picks up the processed copper part 4 and lifts it up.

[0046] Simultaneously, the side bevel gear 209 drives the inner drive wheel 215 to rotate via the inner drive belt 214. The inner drive wheel 215 drives the sliding wheel 217 and the square shaft 205 to rotate via the vertical drive belt 216. The square shaft 205 drives the lead screw 203 to rotate via the outer drive belt 204. The rotation of the lead screw 203 causes the internal thread block 221 to slide along the square groove at the bottom of the sliding box 202. For a period of time before the internal thread block 221 moves, the sliding box 202 will not move because the internal thread block 221 is sliding in the square groove of the sliding box 202. This allows the copper part 4 to rise vertically when it is lifted from the conveyor belt 302 or between the inner mold 113 and the outer mold 104, preventing the copper part 4 from colliding with the forming head 110 or the main frame 101 during the lifting process. After the front end of the internal thread block 221 contacts the sliding box 202... The internal thread block 221 continues to move, which will drive the sliding box 202 to slide along the connecting frame 201. At the same time as the rotating arm 208 rotates, the sliding box 202 moves laterally relative to the connecting frame 201. When the sliding box 202 moves to the limit position, the copper part 4, which was originally above the feeding conveyor belt 302, is moved between the outer mold 104 and the inner mold 113. The copper part 4, which was originally in the processing position, is moved above the conveyor belt 302 used for discharging. Then the inner mold 113 and the outer mold 104 clamp the copper part 4 to be processed. After clamping, the clamping plate 213 is released, and the conveyor belt 302 sends out the processed copper part 4. Then the transfer motor 206 reverses, and the internal thread block 221 slides in the square groove of the sliding box 202. At this time, the lower rotating arm 211 and the clamping plate 213 rise to prevent affecting the processing.

[0047] The electric cylinder inside the main frame 101 drives the outer mold 104 to move slightly. At the same time, the clamping electric cylinder 102 extends, causing the clamping table 103 and the inner mold 113 to slide along the horizontal guide rail 105, so that the inner mold 113 and the outer mold 104 clamp and fix the copper part 4. The electric cylinder inside the main frame 101 drives the movable slide table 112 and the lower sliding block 109 to slide along the main frame 101, so that the first group of forming heads 110 reach both ends of the copper part 4. At this time, the docking slide head 107 is located in the groove of the inner push block 108 of the first group. At this time, the two forming electric cylinders 106 extend, driving the inner push blocks 108 and the forming heads 110 located at both ends of the copper part 4 to move inward along the forming track 111, thus forming the copper part 4. The forming head 110 cold-presses the copper part 4. Then, the forming cylinder 106 retracts, returning the forming head 110 and the inner push block 108 to their initial positions. The lower sliding block 109 then continues to slide, causing the second set of forming heads 110 to reach both ends of the copper part 4. At this point, the docking slide head 107 is located in the sliding groove of the second set of inner push blocks 108. The forming cylinder 106 extends, and the copper part 4 is cold-pressed through the second set of forming heads 110. After the forming head 110 and inner push block 108 return to their original positions, the lower sliding block 109 slides again. Multiple forming processes of the copper part 4 are achieved through the multiple sets of forming heads 110, ultimately resulting in the finished product. Then, the forming cylinder 106, inner push block 108, and forming head 110 return to their initial positions. After processing, the transfer motor 206 reverses, causing the two lower rotating arms 211 to return to their initial positions for the next removal and placement of the copper part 4, repeating this process.
