Description

Technical Field

[0001] This invention relates to the field of cold drawing, and in particular to a continuous precision drawing and cutting process and complete set of equipment for copper guide bars. Background Technology

[0002] Copper conductors are long, strip-shaped conductive components made from pure copper or copper alloys (such as silver-containing copper, chromium-zirconium copper, etc.) through processes such as extrusion and drawing. Precision drawing is a processing method in the cold drawing process of metals. It refers to forcibly drawing a metal billet (such as copper, aluminum, steel, etc.) through a set of dimensionally precise and surface-smooth cemented carbide or diamond dies at room temperature, thereby reducing the cross-section of the metal and extending its length, thus obtaining extremely high dimensional tolerances and excellent surface roughness.

[0003] Existing drawing equipment often uses single-cylinder double-acting hydraulic cylinders or chain-driven drawing trolleys. After each drawing is completed, the machine must be stopped to remove the tooth marks at the front end before the next drawing can begin. This results in poor production continuity and reduces the efficiency of drawing production.

[0004] Therefore, it is necessary to provide a new set of equipment for continuous precision drawing and cutting of copper guide bars to solve the above-mentioned technical problems. Summary of the Invention

[0015] A process for a complete set of equipment for continuous precision drawing and fixed-length cutting of copper guide bars includes the following steps: Step 1: First, adjust the positions of the drawing die, processing components, and support plate in the equipment so that the drawing die can draw copper guide bars of the required specifications and the processing components can cut copper guide bars of the required length. Step 2: First, pass the end of the copper guide bar through the guide roller and the liquid guide ring, and extend it to the bottom of the processing component through the corresponding drawing die, so that the clamping plate in the corresponding processing component can clamp the copper guide bar that passes through the drawing die. Step 3: The controller of the terminal controls the motor to drive the sprocket to rotate, and the sprocket drives the adapter frame to rotate along the circular guide rail by meshing with the chain. The movement of the adapter frame drives the corresponding processing components to rotate synchronously, so that the processing components can pull the copper guide bar held below. Step 4: When the moving processing components move sequentially to the external part opposite to the support plate, the corresponding switch can be driven by the mutual repulsion between the driving magnetic block and the positioning magnetic block, thereby controlling the corresponding clamping plate and electric clamp to work. This controls the clamping and cutting state of the copper guide strip, and the cut copper guide strip can automatically fall downwards. Step 5: After the cut copper guide strip is collected by the collection component located on the preferred side of the processing component, the worker can pull the baffle to release the restriction on the copper guide strip, thus making it easier to unload the copper guide strip.

[0016] Compared with related technologies, the complete set of equipment for continuous precision drawing and fixed-length cutting of copper guide bars provided by the present invention has the following beneficial effects: 1. The present invention suspends the processing component by supporting the component, so that the processing component can rotate along the annular guide rail during the copper guide bar pulling and cutting process. Therefore, continuous pulling and cutting of copper guide bars can be achieved. Compared with the traditional chain-driven traction trolley method, the time wasted when the traction trolley is reset can be reduced, thus improving the continuity of the operation of the processing device. 2. By suspending the drive component above the frame, the present invention can reduce the probability of small metal scraps falling into the chain and causing jamming of the chain drive component during the processing. 3. The present invention uses a suspended conveyor for the processing components. After the copper guide bar is pulled and cut, the cut copper guide bar will fall directly into the material without the need for additional material guide components to guide the cut copper guide bar. Therefore, the material can be cut into the copper guide bar more smoothly. 4. Before use, the position of two adjacent processing components can be adjusted as needed, thus changing the length of the copper guide strip after the two processing components are pulled and cut, thereby improving the processing flexibility of this device. 5. In this invention, by installing the mounting plate, the mounting plate can be rotated as needed before use to adjust the position of the drawing dies of multiple specifications inside, thus enabling the device to process copper guide bars of various specifications.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 13 The present invention provides a complete set of equipment for continuous precision drawing and cutting of copper guide bars. The complete set of equipment for continuous precision drawing and cutting of copper guide bars includes: a frame 1, a drawing die 2 for drawing copper guide bars on the frame 1, a processing component 3 for traction and cutting of copper guide bars on the extrusion, and a guide roller 11 for guiding copper guide bars rotatably mounted on the frame 1.

[0022] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4Above the frame 1 is a support assembly 4 for suspending the processing components 3. The support assembly 4 includes an annular guide rail 41, which is fixedly mounted on the top of the frame 1. The annular guide rail 41 contains sprockets 42 and chains 43 that drive the processing components 3. Multiple processing components 3 are evenly distributed on the chains 43. The sprockets 42 and chains 43 are meshed together. Two sprockets 42 are symmetrically distributed within the annular guide rail 41. The sprockets 42 are rotatably connected to the annular guide rail 41 via shafts. A motor for driving the sprockets 42 is fixedly mounted on the top of the annular guide rail 41. Multiple evenly distributed fixing frames 44 are fixedly mounted on the outer chain plate of the chain 43. A fixedly connected adapter frame 45 is bolted to each fixing frame 44. A rotatably connected guide block 451 is mounted on the top of the adapter frame 45. The outer wall of the adapter frame 45 abuts against and slides against the inner wall of the annular guide rail 41. A fixedly connected support frame 46 is installed at the end of the adapter frame 45. An adjustable rod 47 is rotatably connected inside the support frame 46. An adjustable block 471 is threadedly connected on the adjustable rod 47. A guide groove 461 is opened at the bottom of the support frame 46. The inner wall of the guide groove 461 abuts against and slides against the outer wall of the adjustable block 471. The bottom end of the adjustable block 471 extends to the bottom of the support frame 46 and is fixedly installed with an adapter plate 472. An adapter frame 48 is fixedly installed at the bottom of the adapter plate 472 by bolts. One end of the adjustable rod 47 extends to the end of the support frame 46 and is fixedly connected with a limiting wheel 473. A threadedly connected limiting rod 462 is inserted at the bottom of the support frame 46 opposite to the limiting wheel 473. The end of the limiting rod 462 extends into the limiting hole on the arc surface of the limiting wheel 473.

[0023] It should be noted that by suspending the processing component 3 through the support component 4, the processing component 3 can rotate cyclically along the annular guide rail 41 during the copper guide bar pulling and cutting process. Therefore, continuous pulling and cutting of the copper guide bar can be achieved. Compared with the traditional method of driving the traction trolley with the chain 43, the time wasted when the traction trolley is reset can be reduced, thus improving the continuity of the operation of this processing device. Through the sliding connection between the guide block 451 and the annular guide rail 41, when the chain 43 drives the adapter frame 45 to move through the fixed frame 44, the moving adapter frame 45 will drive the top guide block 451 to move along the inside of the annular guide rail 41. Thus, the adapter frame 45 can be suspended through the hanging between the guide block 451 and the adapter frame 45, thereby enabling the adapter frame 45 to stably drive the processing component 3 below to move, improving the stability of the adapter frame 45 in supporting the processing component 3. In this embodiment: Since the adapter frame 45 and the fixed frame 44 are fixedly connected by bolts, when using the device, the adapter frame 45 can be moved to the corresponding fixed frame 44 according to the required length of the copper guide strip to be cut, and fixed with bolts. Since the distance between two adjacent fixed frames 44 is relatively large, and there is still a slight difference in the spacing between the processing components 3 after the initial adjustment, the adjusting rod 47 can be controlled to rotate. The rotating adjusting rod 47 will drive the adjusting block 471 to move through the thread structure, so that the mounting frame 31 and other components below can move synchronously. Thus, the distance between the mounting frame 31 and the clamping plate 33 below in the processing component 3 can be finely adjusted, thereby achieving precise adjustment of the distance of the processing component 3. After the electric clamp 35 in the processing component 3 completes the cutting of the copper guide strip, the length of the copper guide strip can be smoothly at the required cutting length, so that the device can flexibly cut copper guide strips of different lengths. Furthermore, the adjusting rod 47 is also fitted with a protective cover to protect its external thread structure, thus preventing external impurities from falling onto the thread structure and hindering the rotation of the adjusting rod 47 during use. Meanwhile, since the chain 43 and sprocket 42 are suspended, and protective covers can be installed on the outside of the chain 43 and sprocket 42, compared with the traditional ground-mounted installation, the metal shavings generated during processing can be reduced from falling between the chain 43 and sprocket 42, which could cause jamming in the meshing of the chain 43 and sprocket 42. Therefore, the processing component 3 can be stably driven. Furthermore, the top of the annular guide rail 41 is also equipped with a sliding contact line that supplies power to the electrical equipment in the device, thereby enabling the processing component 3 to be electrically connected smoothly when it rotates in an annular shape.

[0024] In an embodiment of the present invention, please refer to Figure 1 , Figure 5 and Figure 6The processing component 3 includes a clamping plate 33 for holding the copper guide bar. Two sets of clamping plates 33 are symmetrically distributed, and an electric clamp 35 for cutting the copper guide bar is provided between the two sets of clamping plates 33. Both sides of the adapter frame 48 have guide posts 311 slidably connected through through holes. The bottom ends of the guide posts 311 on both sides are fixedly mounted with the same mounting frame 31, and an electric push rod 34 is fixedly connected between the mounting frame 31 and the adapter frame 48. The bottom of the mounting frame 31 is fixedly connected to the electric clamp 35. Both sides inside the mounting frame 31 are equipped with... The rotating rod 32 is rotatably connected. Both sides of the rotating rod 32 are fitted with threaded moving blocks 321. The thread directions of the threaded structures on both sides of the outer wall of the same rotating rod 32 are opposite. The bottom end of the moving block 321 extends to the bottom of the mounting frame 31 and is fixedly connected to the top of the corresponding clamping plate 33. The bottom sides of the mounting frame 31 are provided with sliding grooves 312 at the parts opposite to the rotating rod 32. The inner wall of the sliding groove 312 abuts against and slides with the outer wall of the moving block 321. A motor for controlling the rotation of the rotating rod 32 is fixedly installed at the end of the mounting frame 31.

[0025] It should be noted that: since the threaded structures on both sides of the outer wall of the rotating rod 32 are opposite, when the rotating rod 32 rotates, the opposite threaded structures will drive the moving blocks 321 on both sides of the outer wall to move relative to or away from each other along the slide groove 312, thereby controlling the clamping state of the clamping plate 33 on the copper guide bar. In addition, the rotating rod 32 is also fitted with a threaded protective cover to protect its external threaded structure, reducing the phenomenon of external impurities falling on the threaded structure and causing blockage of the rotating rod 32 during use, so that the rotating rod 32 can rotate stably. In this embodiment, the jaws of the clamping plate 33 and the electric clamp 35 are on the same horizontal plane. Therefore, after the clamping plate 33 finishes clamping the copper guide bar, the electric clamp 35 can smoothly cut the copper guide bar. Meanwhile, through the sliding connection between the guide post 311 and the adapter frame 48, the vertically distributed guide post 311 can move synchronously during the telescopic movement of the electric push rod 34, thereby improving the lateral pressure resistance of the electric push rod 34. This reduces the probability of the electric push rod 34 bending and being damaged due to lateral tension when pulling the copper guide bar, thus improving the working stability of the electric push rod 34.

[0026] In an embodiment of the present invention, please refer to Figure 1 , Figure 9 , Figure 10 , Figure 11 and Figure 12A mounting plate 7 is fixedly connected to the outer wall of the adapter frame 48. Four sets of positioning rods 71 ​​are fixedly installed on the outer wall of the mounting plate 7. Each set of positioning rods 71 ​​includes two rods 71, which are symmetrically distributed vertically. A sliding piece 711 with the same sliding connection is sleeved between the two positioning rods 71 ​​in the same set. A switch 72 is fixedly installed on the outer wall of the mounting plate 7 at the position opposite to each sliding piece 711. A return spring 73 is fixedly connected between the mounting plate 7 and the sliding piece 711. One end of the return spring 73 is fixedly connected to the mounting plate 7, and the other end of the return spring 73 is fixedly connected to the sliding piece 711. A positioning magnetic block 74 is fixedly installed on the outer wall of each sliding piece 711. Multiple positioning magnetic blocks 74 are inclined along the vertical direction. The multiple positioning magnetic blocks 74 are arranged from left to right as magnetic block a, magnetic block b, magnetic block c, and magnetic block d. A ring guide rail 41 is also included. A support rail 5 is fixedly installed on the top of the support plate 7. Three evenly distributed support plates 51 are provided below the support rail 5. Symmetrically distributed protruding rods 52 are fixedly installed on the top of the support plates 51. The top of the protruding rods 52 extends above the support rail 7. A limiting sleeve 521 for fixing the protruding rods 52 is fitted on the outside of the protruding rods 52 through a threaded structure. The bottom end of the limiting sleeve 521 abuts against the top of the support rail 5. Drive magnetic blocks 53 are fixedly installed on the side wall of the support plate 51 near the mounting plate 7. There are three drive magnetic blocks 53 on the leftmost support plate 51, which correspond to the positions of magnetic blocks a, b, and c. There are two drive magnetic blocks 53 on the middle support plate 51, which correspond to the positions of magnetic blocks b and d. There are two drive magnetic blocks 53 on the rightmost support plate 51, which correspond to the positions of magnetic blocks a and c.

[0027] It should be noted that: each group of positioning magnetic blocks 74 has four, which are distributed obliquely along the vertical direction, and from left to right are magnetic block a, magnetic block b, magnetic block c and magnetic block d. Magnetic block a is opposite to the switch 72 of the electric push rod 34, magnetic block b is opposite to the motor switch 72 of the right rotating rod 32, magnetic block c is opposite to the motor switch 72 of the left rotating rod 32, and magnetic block d is opposite to the switch 72 of the electric clamp 35. The driving magnetic blocks 53 on the left support plate 51 include three, which correspond to magnetic blocks a, b and c respectively. The driving magnetic blocks 53 on the middle support plate 51 include two, which correspond to magnetic blocks b and d respectively. The driving magnetic blocks 53 on the right support plate 51 include two, which correspond to magnetic blocks a and c respectively. Furthermore, in use, when the positioning magnetic block 74 moves to the position opposite to the left driving magnetic block 53, the corresponding driving magnetic block 53 will drive it through the mutual repulsion force with the positioning magnetic block 74. Therefore, the corresponding magnetic blocks a, b, and c can be pressed against the corresponding electric push rod 34 switch 72, the right rotating rod 32 motor switch 72, and the left rotating rod 32 motor switch 72 to control the corresponding components to work. The working electric push rod 34 will drive the lower clamping plate 33 to move downwards, so that it moves to the position opposite to the copper guide bar. At this time, the rotation of the two rotating rods 32 will drive the corresponding clamping plate 33 to move relative to each other, so that it clamps and pulls the copper guide bar. When the positioning magnetic block 74 moves to the position opposite to the central driving magnetic block 53, the corresponding driving magnetic block 53 will use the mutual repulsion force with the positioning magnetic block 74 to cause magnetic blocks d and b to squeeze and drive the corresponding switch 72, thereby enabling the electric clamp 35 to cut the copper guide bar between the two clamping plates. At the same time, the rotating rod 32 on the right side rotates in the opposite direction, causing the corresponding clamping plate 33 to release the clamping of the copper guide bar, thereby allowing the copper guide bar end fertilizer from the previous traction to fall downwards. As the positioning magnetic block 74 continues to move and reaches the position opposite to the right driving magnetic block 53, the corresponding driving magnetic block 53 will use the repulsive force with the positioning magnetic block 74 to cause magnetic blocks a and c to squeeze and drive the corresponding switch 72. At this time, the left rotating rod 32 can rotate in the opposite direction to drive the corresponding clamping plate 33 to release the clamping of the copper guide strip. During this process, when the left clamping plate 33 releases the clamping of the copper guide strip, the subsequently moving right clamping plate 33 can also simultaneously clamp the copper guide strip. Therefore, the cut copper guide strip can fall down smoothly. The telescopic electric push rod 34 will drive the corresponding clamping plate 33 to reset so that it will not collide with the copper guide strip during later rotation, thus affecting its rotation trajectory. Therefore, it can stably perform continuous pulling and cutting processing of the copper guide strip in the later stage. In this embodiment: by setting the reset spring 73, when the driving magnetic block 53 separates from the positioning magnetic block 74, the reset spring 73 will squeeze the sliding plate with its own force, so that the sliding plate can be separated from the corresponding switch 72, and the switch 72 can be reset smoothly.

[0028] In an embodiment of the present invention, please refer to Figure 1 , Figure 7 and Figure 8The drawing die 2 is provided with multiple dies arranged in a ring. A mounting plate 6 for supporting the drawing die 2 is rotatably mounted on the frame 1. The mounting plate 6 has a mounting groove for mounting the drawing die 2 inside. Multiple insertion holes 61 are provided on one side wall of the mounting plate 6. A rotating wheel 62 is fixedly mounted on the other side wall of the mounting plate 6. A support ring 63 is fixedly mounted on the top of the frame 1 near the insertion hole 61. The support ring 63 is located outside the mounting plate 6. Multiple fixedly connected guide rods 631 are fixedly mounted on the outer wall of the support ring 63. A sliding frame 632 with the same sliding connection is sleeved on the outer side of the multiple guide rods 631. Insert rods 633 are fixedly mounted on the side wall of the sliding frame 632 near the insertion hole 61, and the end of the insert rod 633 is inserted into the insertion hole 61. Multiple fixedly connected compression springs 64 are installed between the sliding frame 632 and the support ring 63. One end of the compression spring 64 is fixedly connected to the end of the guide rod 631, and the other end of the compression spring 64 is fixedly connected to the support ring 63.

[0029] It should be noted that when the operator pulls the sliding frame 632, it can drive the insertion rod 633 on the side wall to move synchronously, thereby allowing the insertion rod 633 to move out of the insertion hole 61, releasing the obstruction to the rotation trajectory of the mounting plate 6. Then, the rotating wheel 62 on the other side of the mounting plate 6 can be gripped and driven. At this time, the drive wheel will drive the mounting plate 6 to rotate, thereby allowing the internal drawing die 2 to be flexibly adjusted, so that this device can draw copper guide bars of various specifications. After adjusting the drawing die 2, the sliding frame 632 can be released. At this time, the sliding frame 632 will slide back along the guide rod 631 under the force of the compression spring 64. When the insertion rod 633 is reinserted into the insertion hole 61, the mounting plate 6 can be limited so that the mounting plate 6 can stably support the drawing die 2.

[0030] In an embodiment of the present invention, please refer to Figure 1 and Figure 13 A collection chamber 12 is fixedly installed at the top of the frame 1 near the guide roller 11. Horizontal bars 9 are fixedly installed on both sides inside the collection chamber 12. The ends of the horizontal bars 9 on both sides are fixedly mounted with the same liquid guiding ring 91. Multiple connected nozzles 92 are fixedly installed inside the liquid guiding ring 91. The multiple nozzles 92 are distributed in a ring along the inside of the liquid guiding ring 91. A collection assembly 8 for collecting the cut copper guide strip is installed on the top of the frame 1 away from the guide roller 11. The collection assembly 8 includes a collection frame 81, which is fixedly connected to the top of the frame 1. The bottom of the collection frame 81 is an inclined boss, and a slidably connected baffle 82 is inserted into the side of the collection frame 81 near the lower surface of the boss.

[0031] It should be noted that the interior of the liquid guiding ring 91 is also connected to the external "drawing fluid" delivery pipe through a connecting pipe. Thus, during use, the "drawing fluid" can be delivered into the liquid guiding ring 91 and the nozzle 92, and sprayed onto the copper guide strip inside through the nozzle 92, thereby lubricating the copper guide strip and making the drawing of the copper guide strip smoother. In this embodiment: Since the bottom of the collection frame 81 is an inclined boss structure, after the cut copper guide strip falls into the collection frame 81, the worker can lift the baffle 82. At this time, the baffle 82 located in the collection frame 81 will discharge the material downward in the collection frame 81 by gravity. Therefore, it is convenient for the worker to transfer the cut copper guide strip. Since the processing component 3 is suspended, after the processing component 3 completes the cutting of the copper guide strip, the copper guide strip can automatically fall into the collection frame 81 for collection. There is no need to set up additional material guiding components to guide the copper guide strip, which makes the worker more flexible in transferring the copper guide strip later.

[0032] A process for a complete set of equipment for continuous precision drawing and fixed-length cutting of copper guide bars includes the following steps: Step 1: First, adjust the positions of the drawing die 2, processing component 3 and support plate 51 in the equipment so that the drawing die 2 can draw the copper guide bar of the required specifications and the processing component 3 can cut the copper guide bar of the required length. Step 2: First, pass the end of the copper guide bar through the guide roller 11 and the liquid guide ring 91, and extend it to the bottom of the processing component 3 through the corresponding drawing die 2, so that the clamping plate in the corresponding processing component 3 can clamp the copper guide bar that passes through the drawing die 2. Step 3: The controller of the terminal controls the motor to drive the sprocket 42 to rotate, and the sprocket 42 drives the adapter frame 45 to rotate along the annular guide rail 41 by meshing with the chain 43. The movement of the adapter frame 45 drives the corresponding processing component 3 to rotate synchronously, so that the processing component 3 can pull the copper guide bar held below. Step 4: When the moving processing component 3 moves sequentially to the external position opposite to the support plate 51, the corresponding switch 72 can be driven by the mutual repulsion between the driving magnetic block 53 and the positioning magnetic block 74 to control the corresponding clamping plate 33 and electric clamp 35 to work, thereby controlling the clamping and cutting state of the copper guide strip, and the cut copper guide strip can automatically fall downwards. Step 5: After the cut copper guide strip is collected by the collection component 8 located on the preferred side of the processing component 3, the operator can pull the baffle 82 to release the restriction on the copper guide strip, thereby making it easier to unload the copper guide strip.

[0033] The working principle of the complete set of equipment for continuous precision drawing and fixed-length cutting of copper guide bars provided by the present invention is as follows: Before using this equipment, the operator can pull the sliding frame 632 to move it away from the mounting plate 6 along the guide rod 631. The moving sliding frame 632 will then move the insertion rod 633 on the outer wall synchronously, allowing the insertion rod 633 to move out of the insertion hole 61 and releasing the restriction on the rotation trajectory of the mounting plate 6. During this process, the operator can hold the rotating wheel 62 on the other side of the mounting plate 6 and apply rotational force to rotate the mounting plate 6. The rotating mounting plate 6 will drive the internal drawing die 2 to rotate, thereby enabling the adjustment of the position of multiple drawing dies 2. When the drawing die 2 of the required specification is moved to the required position, the rotation of the rotating wheel 62 can be stopped, and the pulling of the sliding frame 632 can be released. At this time, the sliding frame 632 will be driven by the compression spring 64 to reset the insertion rod 633 and re-insert it into the insertion hole 61 to limit the rotation trajectory of the mounting plate 6. At this time, the adjusted drawing die 2 can be fixed. Next, the adapter frame 45 in the three sets of support components 4 can be connected to the corresponding fixed frame 44 in sequence as needed. When there is a slight deviation between the distance between two adjacent sets of processing components 3 and the required cutting length, the adjusting rod 47 can be controlled to rotate. The rotating adjusting rod 47 will drive the adjusting block 471 to slide along the guide groove 461 through the threaded structure on the outer wall. The moving adjusting block 471 will drive the processing component 3 below to move through the adapter plate 472 below. Therefore, the distance between the processing components 3 can be precisely adjusted, so that the copper guide strip cut by the processing component 3 in the later stage can smoothly reach the required length. After adjusting the distance of the processing component 3, the operator can pass the copper guide bar to be processed through the guide roller 11, the liquid guide ring 91 and the drawing die 2 in sequence. This allows the traction end of the copper guide bar to move to the other side of the drawing die 2. Then, the controller at the terminal can control the motor to drive the sprocket 42 to rotate. The rotating sprocket 42 will drive the externally meshed chain 43 to rotate synchronously. At this time, the rotating chain 43 can drive the adapter frame 45 to rotate synchronously through the fixed frame 44 on the outer chain plate. The adapter frame 45 will rotate along the annular guide rail 41 through the top guide block 451, thereby stably driving the processing component 3 below to move. During this process, when the mounting plate 7 moves the external positioning magnetic block 74 to the position opposite to the driving magnetic block 53 on the rightmost support plate 51, the driving magnetic block 53 can drive the corresponding sliding plate 711 to move through the mutual repulsion force between it and the positioning magnetic block 74. At this time, the sliding plate will press the corresponding switch 72 on the back, thereby controlling the motor of the corresponding electric push rod 34 and the two sides control rotation rod 32 to rotate. The working electric push rod 34 drives the clamping plate 33 below to move downward through the mounting frame 31, so that the clamping plate 33 can move to the outside of the copper guide bar below. The rotating motor can drive the corresponding rotating rod 32 to rotate. At this time, the rotating rod 32 can drive the corresponding clamping plate 33 to move relative to each other through the thread structure with opposite thread directions on both sides of the outer wall. When the clamping plate 33 abuts against the outer wall of the copper guide bar, the copper guide bar can be clamped. Therefore, by moving the processing component 3, the copper guide bar can be pulled. During the pulling process, the external liquid "such as wire drawing liquid" can flow into the liquid guide ring 91 and the nozzle 92 through the liquid inlet pipe, and spray it to the outside of the copper guide bar through the nozzle 92, so that the copper guide bar can be pulled more smoothly. As the processing component 3 continues to move, when the processing component 3 moves to the position opposite to the positioning magnetic block 74 on the middle support plate 51, the switch 72 of the electric clamp 35 can be squeezed and driven to cut the copper guide bar. At the same time, the switch 72 of the right motor can also be squeezed to control the motor to drive the right rotating rod 32 to rotate in the opposite direction, so that the corresponding clamping plate 33 releases the clamping of the copper guide bar. At this time, the end scrap of the copper guide bar can fall downward. When the processing component 3 moves to the position opposite to the positioning magnetic block 74 on the rightmost support plate 51, the switch 72 of the left motor can be pressed to control the clamping plate 33 to release the copper guide strip. At this time, in combination with the subsequent processing component 3, the cut copper guide strip can be discharged downwards. At the same time, the rightmost drive magnetic block 53 can also drive the switch 72 of the electric push rod 34, so that the electric push rod 34 drives the mounting frame 31 and other components to reset, so that the clamping plate 33 moves above the copper guide strip. This avoids the phenomenon that when the clamping plate 33 moves above the copper guide strip during the subsequent cyclic rotation, the clamping plate 33 and the copper guide strip will abut against each other, which would hinder the continuous movement trajectory of the processing component 3. Therefore, the processing component 3 can continuously and stably perform the pulling and cutting processing of the copper guide strip.
