Description

Technical Field

[0001] This invention relates to the field of copper busbar drawing machine technology, specifically to a drawing device and method for processing high-quality copper busbars. Background Technology

[0002] In the prior art, copper busbars are long strip conductors made of high-purity copper. Their cross-section is usually rectangular or rounded. During processing, a copper busbar drawing machine applies tension to drive the copper busbar through a mold of a specific shape, so as to achieve precise adjustment of the width, thickness and cross-sectional shape of the copper busbar, and reduce surface scratches and improve smoothness.

[0003] The specific processing procedure is as follows: After the billet passes through the mold, one end is clamped by the traction mechanism and pulled to force the billet through the mold. When the copper busbar reaches the preset length, the gripper mechanism clamps the copper busbar, and then the cutting mechanism cuts off the other end of the copper busbar. After the cutting is completed, the traction mechanism releases one end of the copper busbar, and the transverse mechanism drives the clamping mechanism to move to place the copper busbar on the conveying mechanism and transport it to a specific station. The end of the copper busbar that has been deformed by the traction mechanism is then cut off. In the above process, the gripper mechanism, in conjunction with the transverse mechanism, drives the copper busbar to move and place it on the conveying mechanism. During this transfer process, the traction mechanism is in a waiting state until the copper busbar is completely removed from the traction area before it can be reset, forming a clear process break. At the same time, the end of the copper busbar that is clamped by the traction mechanism will inevitably undergo plastic deformation due to the force, and it needs to be cut again at the subsequent station. This process also requires additional cutting equipment, which is more likely to cause scratches on the copper busbar during the cutting and positioning process. Summary of the Invention

[0004] The purpose of this invention is to provide a drawing device and method for processing high-quality copper busbars, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drawing device for processing high-quality copper busbars, comprising a frame 1, a mold 14, a cutting section, and a copper busbar 12 penetrating the mold 14, and further comprising:

[0006] Traction assembly, used to clamp copper busbars;

[0007] The power unit is used to drive the traction assembly to the first cutting position, and the cutting part cuts off the separating end of the copper busbar;

[0008] The transverse component then drives the traction component to move laterally to avoid the mold, and the power unit then drives it to move to the second cutting position, where the cutting part cuts off the clamping end of the copper busbar.

[0009] After the removal is completed, the lateral movement component drives the traction component to reset to the front end of the blank for the next clamping;

[0010] The support section is used to support the pulled-out copper busbar and passively tightens it at the second cutting position to position the copper busbar.

[0011] Preferably, the power unit is a sprocket structure, and its chain is connected to the lateral movement assembly via a connector.

[0012] Preferably, the lower part of the traverse assembly is slidably connected to the frame, and the traction assembly is fixedly installed on the traverse assembly.

[0013] Preferably, the cutting section includes a truss and a cutting machine, the truss being mounted on the upper part of the frame and used to drive the cutting machine to perform horizontal displacement.

[0014] Preferably, the support portion includes:

[0015] The support frame and the machine frame are arranged in parallel.

[0016] Electric actuators, several electric actuators are arranged along the length of the support frame;

[0017] The first support component is located at the output end of the electric push rod closest to the mold;

[0018] The second support is disposed at the conveying end of the remaining electric push rods;

[0019] During the copper busbar pulling process, the electric push rods extend in sequence so that the first support and the second support can support the copper busbar.

[0020] Preferably, the second support includes a second guide frame, and the upper and lower parts of the second guide frame are rotatably connected to second rollers.

[0021] Preferably, the first support component includes a first guide frame, a slider, an elastic element, a first rotating shaft, a second rotating shaft, a closing element, a rack, a torsion spring, a gear, and a trigger frame. The first guide frame is fixed to the output end of the electric push rod. The slider is slidably connected inside the first guide frame. The elastic element applies a thrust to the first guide frame in the direction of the electric push rod. The first and second rotating shafts are rotatably connected. The two ends of the torsion spring are respectively connected to the first and second rotating shafts. The gear is fixedly installed on the first rotating shaft. The closing element is fixedly installed on the second rotating shaft. The rack is fixedly installed on the slider. The rack and gear mesh. The trigger frame is installed on the side of the support frame. When the lateral movement component drives the traction component to move laterally, the electric push rod retracts synchronously, causing the trigger frame to press against the slider. The rack drives the gear to rotate. Under the linkage of the torsion spring, the first and second rotating shafts rotate synchronously, causing the closing element to close, thereby positioning the copper busbar into the first guide frame.

[0022] Preferably, it also includes a lowering plate and a lowering block. The lowering plate is slidably connected to the upper part of the first guide frame, and the lowering block is fixedly installed on the first rotating shaft. After the closing member is closed, the gear continues to rotate. At this time, under the restriction of the closing member, the second rotating shaft cannot rotate, so the torsion spring twists and the first rotating shaft continues to rotate, so that the lowering block squeezes the lowering plate to move down.

[0023] Preferably, the lowering plate, the first guide frame, and the closing member are all rotatably connected to a first roller.

[0024] A method for drawing high-quality copper busbars includes the following steps:

[0025] S1, one end of the copper busbar blank is passed through the mold on the frame, so that the front end of the blank extends out of the mold by a preset length to form a clamping section. The power unit drives the traction component to move towards the front end of the blank until the traction component is aligned with the clamping section. The traction component moves and clamps and fixes the clamping section at the front end of the blank. The electric push rod closest to the mold in the support part extends out, so that the first support component moves to contact the bottom of the blank, and initially supports the part of the blank that extends out of the mold.

[0026] S2, the power unit drives the traction assembly to move along the extension direction of the copper busbar. The clamping force of the traction assembly drives the copper busbar billet to continuously pass through the mold to complete the drawing process. During the drawing process, the electric push rods of the support part extend in sequence along the copper busbar drawing direction, so that the second support part supports the drawn copper busbar segment by segment, ensuring that the copper busbar remains in a horizontal and stable state during the drawing process.

[0027] S3, after the copper busbar is pulled to the preset length, the power unit drives the traction component to stop at the first cutting position, and the truss of the cutting part drives the cutting machine to cut the end of the copper busbar close to the mold;

[0028] S4. After the separation end is cut, the lateral movement component drives the traction component to move laterally, so that the traction component and the clamped copper busbar avoid the mold position. At the same time, the electric push rod in the corresponding position in the support part retracts synchronously to drive the closing member to close and position the copper busbar in the first guide frame. After the closing member is closed, the gear continues to rotate and forces the torsion spring to twist. The first rotating shaft continues to rotate to drive the lower pressure block to squeeze the lower moving plate to move down, which, together with the first guide frame and the closing member, achieves multi-directional positioning of the copper busbar.

[0029] S5, after the copper busbar is positioned, the power unit drives the traction assembly to move to the second cutting position. The truss of the cutting part drives the cutting machine to move to the cutting position of the copper busbar clamping end. The cutting machine then cuts off the copper busbar clamping end. After completion, the cutting machine resets.

[0030] S6, after the clamping end is cut off, the traction component releases its clamping of the copper busbar; the transverse component drives the traction component to reset to the initial position on the same straight line as the mold exit, ready to perform the clamping action of the next drawing process, forming a continuous processing cycle.

[0031] In the above technical solution, the present invention provides a drawing device and method for high-quality copper busbar processing. Through the coordinated action of the lateral movement component and the power unit, the traction component can directly move laterally to avoid the mold after completing the cutting of the separation end. The copper busbar is then transported by resetting the traction component, and then cut a second time by the cutting part. After resetting, it enters the next round of clamping, forming a continuous processing cycle. This avoids the waiting and idle time of the traction mechanism in traditional equipment, greatly shortens the process interval, and significantly improves production efficiency. Moreover, the cutting part completes the two cuttings of the separation end and the clamping end of the copper busbar on the same device, without the need for additional secondary cutting equipment, reducing equipment cost and floor space. At the same time, it avoids the risk of surface scratches caused by the transfer of copper busbar between multiple devices. Attached Figure Description

[0044] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] Please see Figure 1-10 The present invention provides a drawing device for processing high-quality copper busbars, comprising a frame 1, a die 14, a cutting section, and a copper busbar 12 penetrating the die 14, and further comprising:

[0046] Traction assembly 4, which is used to clamp copper busbar 12;

[0047] The power unit 2 is used to drive the traction assembly 4 to the first cutting position, and the cutting part cuts off the separation end of the copper busbar 12.

[0048] The transverse component 3 then drives the traction component 4 to move laterally to avoid the mold 14, and the power unit 2 then drives it to move to the second cutting position, where the cutting part cuts off the clamping end of the copper busbar 12.

[0049] After the removal is completed, the transverse component 3 drives the traction component 4 to reset to the front end of the blank for the next clamping.

[0050] The support part is used to support the pulled-out copper busbar 12 and passively tightens it at the second cutting position to position the copper busbar 12.

[0051] The traction assembly 4 is hydraulically driven, with adjustable clamping force to ensure stable clamping of copper busbars 12 of different sizes. After the traction assembly 4 clamps the copper busbar 12, the power unit 2 drives the traction assembly 4 to move along the frame 1 to pull the copper busbar 12. During the pulling process, the supporting part of the copper busbar 12 is supported, and the movement stops when it reaches the first cutting position. The cutting part starts and precisely cuts the separating end of the copper busbar 12 to complete the initial material feeding. Then, the lateral movement assembly 3 drives the traction assembly 4 to move laterally, and the supporting part retracts synchronously. Then, the power unit 2 drives the traction assembly 4 to move in the opposite direction. In this way, the copper busbar 12 is conveyed synchronously by utilizing the reset stroke of the traction assembly 4. When the copper busbar 12 is conveyed to the second cutting position, the cutting unit starts to cut the clamping end of the copper busbar 12. Finally, it returns to the front end of the mold 14 for the next pull. During this process, the copper busbar 12 is moved synchronously by the reset stroke of the traction component 4 after the separation end is cut. This avoids the problem of the traction mechanism being idle during the movement of the copper busbar 12 in traditional equipment. The copper busbar 12 is moved to the second cutting position by the traction mechanism 4. The separation end and the clamping end are cut twice by the same cutting unit, eliminating the need for secondary cutting equipment. There is no need for secondary clamping and positioning. The clamping point is unique, which minimizes damage to the copper busbar. The cutting path can be dynamically calibrated in real time through preset programs or sensor feedback to meet various cutting needs.

[0052] In this embodiment of the invention, the power unit 2 is a sprocket structure, and its chain is connected to the transverse assembly 3 via a connector. A sprocket transmission mechanism is used, the drive motor is a servo motor, and the drive sprocket is connected to the driving sprocket via a reducer. The driven sprocket is mounted at the other end of the frame 1. The chain is a double-row roller chain, and the chain is fixed to the bottom of the transverse assembly 3 via a rigid connector to ensure synchronized movement.

[0053] In an embodiment of the present invention, the lower part of the transverse component 3 is slidably connected to the frame 1, and the traction component 4 is fixedly installed on the transverse component 3.

[0054] The bottom of the transverse component 3 slides with the top of the frame 1 via a sliding block to achieve sliding along the pulling direction. A transverse slide rail is provided at the top. The traction component 4 is connected to the transverse slide rail via the bottom sliding block. The transverse drive is electric, which ensures that the traction component 4 moves laterally in sync with the support part to ensure the stability of the copper busbar 12. The specific connection method is not shown.

[0055] In an embodiment of the present invention, the cutting section includes a truss 9 and a cutting machine 10. The truss 9 is mounted on the upper part of the frame 1 and is used to drive the cutting machine 10 to perform horizontal displacement.

[0056] The truss 9 is configured as a gantry structure and spans above the frame 1. The truss 9 is equipped with a linear drive module, which drives the cutting machine 10 to move. The cutting machine 10 is a disc saw structure and is equipped with a coolant spray module.

[0057] In another embodiment of the present invention, the support portion includes:

[0058] Support frame 5, which is arranged in parallel with frame 1;

[0059] Electric push rods 6, and several electric push rods 6 are arranged along the length of the support frame 5.

[0060] The first support 11 is located at the output end of the electric push rod 6 closest to the mold 14;

[0061] The second support member 8 is disposed at the conveying end of the remaining electric push rods 6;

[0062] During the pulling process of the copper busbar 12, the electric push rod 6 extends in sequence so that the first support member 11 and the second support member 8 support the copper busbar 12.

[0063] During the pulling process of the copper busbar 12, the electric push rod 6 corresponding to the first support member 11 extends first to support the copper busbar 12. As the pulling progresses, the electric push rod 6 extends in sequence, and the remaining second support member 8 supports the copper busbar 12. This achieves the effect of supporting as the pulling progresses to avoid hindering the movement of the traction component 4. Through the multi-point support of the first support member 11 and the second support member 8, the weight of the copper busbar 12 is distributed to avoid deformation due to gravity.

[0064] In an embodiment of the present invention, the second support member 8 includes a second guide frame 81, and the upper and lower parts of the second guide frame 81 are rotatably connected to second rollers 82.

[0065] The second guide frame 81 is used to support the copper busbar 12, and the second roller 82 achieves rolling connection with the copper busbar 12 to reduce damage to the copper busbar.

[0066] In an embodiment of the present invention, the first support member 11 includes a first guide frame 111, a slider 113, an elastic element 114, a first rotating shaft 115, a second rotating shaft 116, a closing member 118, a rack 1131, a torsion spring 1132, a gear 1133, and a trigger frame 13. The first guide frame 111 is fixed to the output end of the electric push rod 6. The slider 113 is slidably connected within the first guide frame 111. The elastic element 114 applies a thrust to the first guide frame 111 in the direction of the electric push rod 6. The first rotating shaft 115 and the second rotating shaft 116 are rotatably connected. The two ends of the torsion spring 1132 are respectively connected to the first rotating shaft 115 and the second rotating shaft 116. The gear 1133 is fixedly mounted on the first rotating shaft 115, the closing member 118 is fixedly mounted on the second rotating shaft 116, the rack 1131 is fixedly mounted on the slider 113, the rack 1131 and the gear 1133 mesh, the trigger frame 13 is mounted on the side of the support frame 5, when the lateral moving component 3 drives the traction component 4 to move laterally, the electric push rod 6 retracts synchronously, so that the trigger frame 13 squeezes the slider 113, the rack 1131 drives the gear 1133 to rotate, and under the linkage of the torsion spring 1132, the first rotating shaft 115 and the second rotating shaft 116 rotate synchronously, so that the closing member 118 closes, so as to realize the positioning copper busbar 12 into the first guide frame 111.

[0067] When the pull-out is complete, the electric push rod 6 is in the extended state, with the first guide frame 111, the second guide frame 81, and the bottom of the copper busbar 12 in contact and support. After the traction assembly 4 moves laterally, the electric push rod 6 retracts synchronously, while the trigger frame 13 fixed to the side of the support frame 5 remains in the same position. As the first guide frame 111 moves laterally, its slider 113 gradually contacts the trigger frame 13. The slider 113 is subjected to the lateral compression force of the trigger frame 13, overcoming the thrust of the elastic element 114, and slides away from the electric push rod 6 along the groove of the first guide frame 111. During the sliding of the slider 113, the rack 1131 fixed on it moves synchronously, driving the gear 1133 to rotate through the meshing relationship. The first rotating shaft 115 transmits torque to the second rotating shaft 116 through the torsion spring 1132, and the gear 1133 drives the first rotating shaft 115 to rotate synchronously, thereby causing the closing element 118 fixed on the second rotating shaft 116 to flip downwards as shown in the attached figure. Figure 8 As shown, the open end of the first guide frame 111 is closed to ensure the stability of the copper busbar during the resetting process of the traction assembly 4.

[0068] In another embodiment of the present invention, please refer to Figure 8-9It also includes a lowering plate 117 and a lowering block 119. The lowering plate 117 is slidably connected to the upper part of the first guide frame 111, and the lowering block 119 is fixedly installed on the first rotating shaft 115. After the closing member 118 is closed, the gear 1133 continues to rotate. At this time, under the restriction of the closing member 118, the second rotating shaft 116 cannot rotate, so the torsion spring 1132 is twisted, and the first rotating shaft 115 continues to rotate, so that the lowering block 119 squeezes the lowering plate 117 to move down.

[0069] After the closing member 118 completes the positioning of both sides of the copper busbar 12, the continuous rotation of the gear 1133 drives the rotation of the lower pressure block 119, and the lower pressure block 119 will be moved by the attached... Figure 8 The status shown has been switched to attached. Figure 9 As shown, the pressing block 119 applies a pushing force to the lowering plate 117 to press it down, thereby completing the positioning of the upper and lower surfaces of the copper busbar 12. This ensures stability during the movement of the copper busbar 12, and that its two ends are positioned by the traction component 4 and the lowering plate 117 respectively during cutting, so as to reduce shaking during cutting.

[0070] In this way, the retraction of the electric push rod 6 is used to move the copper busbar 12, thereby passively positioning both sides of the copper busbar 12 first. During the continuous displacement, the upper and lower positioning is performed to minimize friction during positioning.

[0071] In an embodiment of the present invention, a first roller 112 is rotatably connected to the lowering plate 117, the first guide frame 111, and the closing member 118.

[0072] The first roller 112 is designed to make rolling contact with the copper busbar 12, thereby reducing scratches on the copper busbar.

[0073] A rounded chamfer needs to be set at the lower part of the first guide frame 111 so that the copper busbar 12 can still be guided into the first guide frame 111 even if it drops a certain amount due to its own weight.

[0074] It should be noted that there is also a conveying device for conveying the copper busbar 12, which is used to receive the copper busbar 12 pushed out by the traction assembly 4. The conveying device is not shown in the figure.

[0075] During reset, the first guide frame 111 moves to the side, the slider 113 disengages from the trigger frame 13, the elastic element 114 releases its stored energy, pushing the slider 113 to reset, the rack 1131 moves in the opposite direction as the slider 113 resets, driving the gear 1133 and the first rotating shaft 115 to rotate in the opposite direction. After the torsion spring 1132 makes torsional contact, the first rotating shaft 115 continues to rotate. At this time, the torque of the torsion spring 1132 is greater than the force required to drive the second rotating shaft 116 to rotate in the opposite direction. Therefore, the torsion spring 1132 plays a connecting role at this time, so that the first rotating shaft 115 and the second rotating shaft 116 can rotate synchronously, so as to reopen the closing member 118.

[0076] A method for drawing high-quality copper busbars includes the following steps:

[0077] S1, one end of the copper busbar 12 blank is passed through the mold 14 on the frame 1, so that the front end of the blank extends out of the mold 14 by a preset length to form a clamping section. The power unit 2 drives the traction component 4 to move towards the front end of the blank until the traction component 4 is aligned with the clamping section. The traction component 4 is activated and clamps and fixes the clamping section at the front end of the blank. The electric push rod 6, which is closest to the mold 14 in the support part, extends out, so that the first support member 11 is displaced to contact the bottom of the blank, and provides initial support for the part of the blank that extends out of the mold 14.

[0078] S2, the power unit 2 drives the traction component 4 to move along the extension direction of the copper busbar 12. The clamping force of the traction component 4 drives the copper busbar 12 billet to continuously pass through the mold 14 to complete the drawing process. During the drawing process, the electric push rod 6 of the support part extends in sequence along the drawing direction of the copper busbar 12, so that the second support part 8 supports the drawn copper busbar 12 segment by segment, ensuring that the copper busbar 12 remains in a horizontal and stable state during the drawing process.

[0079] S3, when the copper busbar 12 is pulled to the preset length, the power unit 2 drives the traction component 4 to stop at the first cutting position, and the truss 9 of the cutting part drives the cutting machine 10 to cut the end of the copper busbar 12 close to the mold 14.

[0080] S4, after the separation end is cut, the transverse component 3 drives the traction component 4 to move laterally, so that the traction component 4 and the clamped copper busbar 12 avoid the position of the mold 14. At the same time, the electric push rod 6 at the corresponding position in the support part retracts synchronously to drive the closing member 118 to close, positioning the copper busbar 12 in the first guide frame 111. After the closing member 118 completes the closure, the gear 1133 continues to rotate and forces the torsion spring 1132 to twist. The first rotating shaft 115 continues to rotate, driving the lower pressure block 119 to squeeze the lower moving plate 117 to move down, which, together with the first guide frame 111 and the closing member 118, achieves multi-directional positioning of the copper busbar 12.

[0081] S5, after the copper busbar 12 is positioned, the power unit 2 drives the traction component 4 to move to the second cutting position, and the truss 9 of the cutting part drives the cutting machine 10 to move to the cutting position of the clamping end of the copper busbar 12. The cutting machine 10 cuts off the clamping end of the copper busbar 12. After completion, the cutting machine 10 resets.

[0082] S6, after the clamping end is removed, the traction component 4 releases its clamping of the copper busbar 12; the transverse component 3 drives the traction component 4 to reset to the initial position on the same straight line as the exit of the mold 14, ready to perform the clamping action of the next drawing process, forming a continuous processing cycle.

[0083] In this embodiment, the lateral movement component 3 and the power unit 2 work together to achieve lateral movement and reverse movement to facilitate cutting, realize multi-point cutting at a single clamping point, eliminate the waiting idle time of the traction component 4 in the traditional process, and improve the efficiency of mass production.

[0084] The first cutting position uses the truss 9 to drive the cutting machine 10 to cut off the separation end, and the second cutting position removes the deformed section of the clamping end. Both cuts are completed by the same cutting part, eliminating the need for secondary cutting equipment.

[0085] The retraction of the electric push rod 6 triggers the mechanical linkage of the first support component 11, thereby achieving the left and right positioning of the copper busbar 12, as well as its vertical positioning, reducing damage to the copper busbar 12 during positioning.

[0086] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
