Description

Technical Field

[0001] This application relates to the field of busbar processing equipment, and in particular to a stamping device for busbars. Background Technology

[0002] A busbar is a rigid conductive busbar used in power distribution systems, typically made of highly conductive metals such as copper or aluminum. Its core function is to collect and distribute large currents, acting as an electrical connection hub to achieve low-impedance, high-reliability power transmission between multiple circuits. It is widely used in distribution cabinets, switchgear, new energy systems, and industrial power installations.

[0003] In related technologies, busbars are stamped using a stamping device. The stamping device includes a conveying drive assembly, a lifting drive source, an upper die, and a lower die. The conveying assembly transports the raw material of the busbar to be stamped, and the stamping assembly drives the upper or lower die to rise and fall, bringing the upper and lower dies closer together to stamp the material into shape. Existing stamping devices, after completing the stamping of the busbar, require a separate cutting device to cut the entire busbar to the required length; or the raw material is first cut by a cutting device before being stamped by the stamping device. Therefore, stamping and cutting the busbar often require two steps, resulting in low processing efficiency. Summary of the Invention

[0004] To improve the processing efficiency of busbars, this application provides a stamping device for busbars.

[0005] This application provides a stamping device for a busbar, which adopts the following technical solution: A busbar stamping device includes a conveying drive assembly, a lifting drive source, an upper die, and a lower die. The conveying drive assembly is used to convey the busbar, the lifting drive source is used to drive the upper die to rise and fall, and the upper die and lower die are used to close the die to stamp the busbar. The device also includes a cutting drive assembly and a cutting component that is slidably disposed on the upper die in a vertical direction. The cutting drive assembly is used to drive the cutting component to rise and fall, and the cutting component is used to cut the busbar. The upper surface of the lower die has a clearance groove corresponding to the cutting component for insertion.

[0006] By adopting the above technical solution, and by adding a cutting drive assembly and a sliding cutting component, the cutting function is directly integrated into the stamping device. After a certain length of busbar is stamped, the cutting drive assembly drives the cutting component to descend, and the cutting component inserts into the clearance groove of the lower die to shear the busbar. This achieves immediate cutting of the busbar after stamping, eliminating the separate cutting process in traditional processes. This design significantly shortens the processing flow, avoids efficiency losses caused by material transfer, and reduces equipment footprint and operational complexity.

[0007] Optionally, the cut-off piece is block-shaped, extends along the conveying direction of the busbar, and the length of the cut-off piece is equal to the distance between two adjacent connecting feet of the busbar.

[0008] By adopting the above technical solution, if the cutting blade is sheet-shaped and cuts between adjacent connecting feet of the busbar, directly cutting the strip-shaped busbar into two sections, a section of waste material remains in the cut busbar. That is, the connecting foot at the end of the busbar's length direction is not flush with the end face of the busbar (because the connecting feet at both ends of the busbar processed in this application are flush with the surfaces of the beginning and end ends along the length direction). This waste material needs to be cut again, or the busbar can be directly delivered to the customer for self-cutting, which will result in some material waste. This application limits the cutting blade to be block-shaped and its length to match the spacing between adjacent connecting feet of the busbar, so that the cutting blade cuts the busbar into three sections: one section is the finished busbar, one section is the waste material between adjacent connecting feet, and one section is the busbar to be processed. In this way, the finished busbar can directly meet the usage requirements, and the cut waste material can also be recycled, reducing material waste.

[0009] Optionally, the upper mold is provided with at least two sets of stamping parts arranged in a direction perpendicular to the vertical direction and perpendicular to the conveying direction of the busbar, the lower mold is provided with stamping grooves corresponding to the stamping parts for insertion, and the cutting parts are provided with at least two sets corresponding to the stamping parts one by one. Each set of stamping parts is staggered in the conveying direction of the busbar, and each set of cutting parts is staggered in the conveying direction of the busbar.

[0010] By adopting the above technical solution and setting up multiple sets of stamped parts and cut-off parts, multiple busbars can be processed simultaneously by one device, significantly improving production efficiency. The staggered distribution of multiple sets of stamped parts and cut-off parts minimizes the space occupied by the mold in the width direction while avoiding interference during the operation of multiple mechanisms, resulting in a compact device structure and miniaturization.

[0011] Optionally, the cutting drive assembly includes a cutting drive source and a transmission plate. The cutting drive source is used to drive the transmission plate to slide along the conveying direction of the busbar. An inclined transmission surface is formed on the lower surface of the end of the transmission plate facing the cutting part. The distance between the transmission surface and the cutting part increases in the vertically downward direction. The transmission surface is used to slide against the cutting part and push the cutting part down. A reset elastic element is connected between the cutting part and the upper mold to lift and reset the cutting part.

[0012] By adopting the above technical solution, a combined mechanism of a transmission ramp and a return elastic element is used to convert the lateral movement of the cutting drive source into the vertical lifting and lowering of the cutting part. The cutting drive source can be positioned on the side of the upper die, avoiding interference between the cutting drive source and the lifting drive source. The ramp transmission structure has a self-locking characteristic, providing stable downward pressure; the return elastic element ensures automatic return after cutting, eliminating the need for an additional drive source. This design simplifies the mechanical structure, reduces energy consumption, and ensures coordination between the cutting action and the main stamping stroke.

[0013] Optionally, the cutting component includes a cutting component body and a roller rotatably mounted on the cutting component body. The rotation axis of the roller extends in a direction perpendicular to the vertical direction and perpendicular to the sliding direction of the transmission plate. The roller is used to roll against the transmission inclined surface.

[0014] By adopting the above technical solution, rollers are added to the body of the cut piece, changing the sliding contact between it and the transmission ramp into rolling friction. This significantly reduces wear and noise during transmission, extending the service life of the cut piece. Simultaneously, the rollers eliminate the component of the force exerted by the transmission plate on the cut piece through the transmission ramp in the direction of movement, ensuring that the cut piece ultimately receives only the vertical component of the force. This reduces the movement resistance of the cut piece, improves transmission efficiency and response speed, and ensures the smoothness and repeatability of the cutting action.

[0015] Optionally, it also includes a translation drive source and a push plate. The translation drive source is used to drive the push plate to slide. The lower mold has a groove that communicates with the relief groove. The push plate is slidably disposed in the groove in the horizontal direction. The push plate can slide to insert into the relief groove. A discharge groove that communicates with the relief groove is formed on the surface of the lower mold opposite to the opening surface of the groove. A button is provided on the groove wall of the relief groove. When the cut piece is inserted into the relief groove, the cut piece can trigger the button. The button is electrically connected to the translation drive source.

[0016] By adopting the above technical solution, automatic waste removal is achieved through the linkage design of the push plate and the button. After the cut part triggers the button, the translation drive source is activated. The translation drive source drives the push plate to insert into the clearance slot, pushing the cut waste out of the mold. This mechanism effectively solves the mold blockage problem caused by waste retention, avoids the safety risks of manual cleaning, minimizes downtime due to manual cleaning of the clearance slot, and ensures the stability of continuous production.

[0017] Optionally, the depth of the relief groove is greater than the depth to which the cut piece is inserted into the relief groove, and the button is located on the bottom wall of the relief groove.

[0018] By adopting the above technical solution, the depth of the clearance groove is greater than the thickness of the cut-out part, and the button is located on the bottom wall of the clearance groove, allowing a certain amount of waste material to accumulate in the clearance groove. When the waste material reaches its limit, the cut-out part is inserted into the clearance groove while pressing down on the waste material, indirectly triggering the button through the waste material, thus activating the translation drive source. This design avoids triggering the button every time the cut-out part is inserted into the clearance groove; triggering the button only after a certain amount of waste material has accumulated reduces the number of times the translation drive source is activated, saving energy. At the same time, the cut-out part triggering the button through the waste material prevents a hard collision between the cut-out part and the button, protecting the precision electronic components.

[0019] Optionally, the translation drive source is used to abut and push the push plate. A restoring elastic element is connected between the push plate and the groove wall of the slide, which causes the push plate to slide in a direction close to the opening surface of the slide. The lower mold is provided with a sliding groove communicating with the slide. A push member is slidably disposed in the sliding groove. An inclined pushing surface is formed on the surface of the push member facing the push plate. The pushing inclined surface is used to slide against the push plate and drive the push plate to slide in the direction of insertion into the relief groove. A return elastic element is connected between the push member and the groove wall of the slide, which causes the push member to slide in a direction away from the push plate.

[0020] By adopting the above technical solution, the driving component of the translation drive source is not fixedly connected to the push plate, but rather pushes the push plate against it. The push plate is reset by the return elastic component. This design allows both the translation drive source and the push component to independently drive the push plate. When the translation drive source or the button malfunctions or is damaged, or when a batch of busbars is processed and waste needs to be uniformly recycled, some waste may remain in the clearance groove. In this case, the push component can push the push plate to push the waste out of the clearance groove, facilitating the cleaning of the remaining waste. The use of a pushing ramp converts the lateral movement of the push component into the lateral-vertical movement of the push plate, facilitating the layout of the push component and avoiding interference between the push component and the translation drive source. The return elastic component and the repositioning elastic component constitute the automatic reset system of the waste ejection mechanism. After the push component is disengaged from the push plate by the repositioning elastic component, the return elastic component drives the push plate back to its initial position. This design completes the ejection-reset cycle without an additional power source, simplifying the control logic and ensuring that the mechanism automatically returns to its original position after each punching cycle, maintaining consistent production rhythm.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By adding a cutting drive component and a sliding cutting component, the cutting function is directly integrated into the stamping device, shortening the processing flow, avoiding efficiency loss caused by material transfer, and reducing the equipment footprint and operational complexity. 2. The cut-off part cuts the busbar into three sections, so that the finished busbar can directly meet the usage requirements, and the cut-off waste can also be recycled, reducing raw material waste; 3. The translation drive source drives the push plate to insert into the relief groove, pushing the cut waste material out of the mold. This mechanism effectively solves the mold blockage problem caused by waste material retention, avoids the safety risks of manual cleaning, minimizes downtime due to manual cleaning of the relief groove, and ensures the stability of continuous production.

[0032] The following combination Figures 1-9 This application will be described in further detail.

[0033] Example 1: Embodiment 1 of this application discloses a stamping device for a busbar. (Refer to...) Figure 1 and Figure 2 and Figure 3 The busbar stamping device includes a frame 150 and a conveying drive assembly 1, a lifting drive source 2, an upper die 3, and a lower die 4 mounted on the frame 150. The conveying drive assembly 1 is used to convey the busbar, the lifting drive source 2 is used to drive the upper die 3 to rise and fall, and the upper die 3 and the lower die 4 are used to close the mold to stamp the busbar. The busbar stamping device also includes a cutting drive assembly 5 and a cutting piece 6 that is slidably disposed on the upper die 3 in the vertical direction. The cutting drive assembly 5 is used to drive the cutting piece 6 to rise and fall, and the cutting piece 6 is used to cut the busbar. The upper surface of the lower die 4 is provided with a relief groove 41 corresponding to the cutting piece 6 for the cutting piece 6 to be inserted.

[0034] Reference Figure 1 The conveying drive assembly 1 includes a conveying drive source 11, a driving wheel 12, and a driven wheel 13. The conveying drive source 11 is fixedly mounted on the frame 150, and the driving wheel 12 and the driven wheel 13 are both rotatably mounted on the frame 150. The conveying drive source 11 is a drive motor, and its output shaft is fixedly connected to the rotation shaft of the driving wheel 12, thereby driving the driving wheel 12 to rotate. The driving wheel 12 and the driven wheel 13 clamp and convey the busbar to be stamped.

[0035] Reference Figure 1 and Figure 2The upper mold 3 includes an upper mounting plate 31, a transition plate 32, and an upper mold body 33. The transition plate 32 is fixedly mounted on the surface of the upper mounting plate 31 near the lower mold 4. The upper mold body 33 is slidably mounted below the transition plate 32 in a vertical direction. A spring (not shown in the figure) connects the upper mold body 33 and the transition plate 32, causing the upper mold body 33 to slide away from the transition plate 32.

[0036] Reference Figure 1 The lifting drive source 2 is fixedly mounted on the frame 150. The lifting drive source 2 is a cylinder, and the piston rod of the lifting drive source 2 is fixedly connected to the upper mounting plate 31, thereby driving the upper mold 3 to rise and fall. When the lifting drive source 2 drives the upper mold 3 to fall, the upper mold body 33 abuts against the lower mold 4. The lifting drive source 2 continues to drive the upper mounting plate 31 to fall, so that the upper mold body 33 overcomes the elastic force of the spring and moves upward relative to the transition plate 32 (in fact, the upper mold body 33 does not move, and the upper mounting plate 31 and the transition plate 32 move downward relative to the upper mold body 33).

[0037] Reference Figure 2 and Figure 3 At least two sets of stamping parts 7 are fixedly mounted on the surface of the transition plate 32 near the upper mold body 33. Each set of stamping parts 7 is arranged in a direction perpendicular to the vertical direction and the conveying direction of the busbar. The sets of stamping parts 7 are staggered in the conveying direction of the busbar. A through hole is provided vertically through the upper mold body 33 for the stamping parts 7 to pass through. A stamping groove 42, corresponding to the stamping parts 7, is provided on the surface of the lower mold 4 near the upper mold 3 for the insertion of the stamping parts 7.

[0038] Reference Figure 2 The cut-off piece 6 is slidably mounted on the transition plate 32 in a vertical direction. A through hole is provided in the upper mold body 33 in a vertical direction for the cut-off piece 6 to pass through. At least two sets of cut-off pieces 6 are provided, each corresponding to one set of stamped pieces 7. Each set of cut-off pieces 6 is arranged in a direction perpendicular to the vertical direction and perpendicular to the conveying direction of the busbar. The sets of cut-off pieces 6 are staggered in the conveying direction of the busbar.

[0039] Reference Figure 2 The cut piece 6 is block-shaped and extends along the conveying direction of the busbar. The length of the cut piece 6 is equal to the distance between two adjacent connecting feet of the busbar.

[0040] Reference Figure 2 The transition plate 32 has a telescopic groove 322 extending vertically on its surface near the upper mold body 33, and the cut piece 6 is slidably installed in the telescopic groove 322.

[0041] Reference Figure 4 and Figure 5The cutting component 6 includes a cutting component body 61 and a roller 62 rotatably mounted on the cutting component body 61 and located above the cutting component body 61. The rotation axis of the roller 62 extends in the front-back direction.

[0042] Reference Figure 5 A reset elastic element 8 is connected between the cut-off piece body 61 and the lower surface of the upper mounting plate 31. The reset elastic element 8 is a tension spring and is located in the telescopic groove 322. The reset elastic element 8 is used to drive the cut-off piece 6 to move upward and reset.

[0043] Reference Figure 4 and Figure 5 The cutting drive assembly 5 includes a cutting drive source 51 and a transmission plate 52. The cutting drive source 51 is fixedly mounted on the upper mounting plate 31. The cutting drive source 51 is a cylinder, and the piston rod of the cutting drive source 51 is fixedly connected to the transmission plate 52, thereby enabling the transmission plate 52 to slide in a direction opposite to the conveying direction of the busbar. The conveying direction of the busbar is set to right to left. A transmission groove 321 extending in the left-right direction is provided on the left side wall of the transition plate 32. The transmission groove 321 communicates with the telescopic groove 322, and the transmission plate 52 is slidably mounted in the transmission groove 321.

[0044] Reference Figure 3 and Figure 5 The lower surface of the transmission plate 52 facing the end of the cut piece 6 is chamfered to form an inclined transmission surface 521, which is inclined upwards towards the right. When the transmission plate 52 moves to the right, the inclined transmission surface 521 rolls against the roller 62, causing the cut piece 6 to descend into the insertion relief groove 41. In other embodiments, the roller 62 may be omitted, and the inclined transmission surface 521 slides against the cut piece body 61.

[0045] The implementation principle of the busbar stamping device in Embodiment 1 of this application is as follows: the conveying drive assembly 1 conveys the busbar to be stamped, the lifting drive source 2 drives the upper mold 3 to descend, so that the upper mold 3 and the lower mold 4 close, and the stamping part 7 stamps the busbar. After stamping a certain length, the cutting drive source 51 drives the transmission plate 52 to slide, the transmission inclined surface 521 rolls and abuts against the roller 62, driving the cutting part 6 to descend and cut the busbar.

[0046] Example 2: Reference Figure 6Unlike Embodiment 1, in this embodiment, the lower mold 4 includes a lower mold body 46 and a lower mounting plate 47, with the lower mold body 46 fixedly mounted on the upper surface of the lower mounting plate 47. Both the stamping groove 42 and the clearance groove 41 are formed on the lower mold body 46. The clearance groove 41 penetrates the lower surface of the lower mold body 46. A discharge groove 44 communicating with the clearance groove 41 is formed on the left side wall of the lower mold body 46, and the discharge groove 44 penetrates the lower surface of the lower mold body 46.

[0047] Reference Figure 7 The busbar stamping device also includes a translation drive source 9 and a push plate 100. The translation drive source 9 is fixedly installed on the lower mold body 46. The translation drive source 9 is a cylinder. The piston rod of the translation drive source 9 is used to push the push plate 100, thereby driving the push plate 100 to move to the left.

[0048] Reference Figure 8 A sliding groove 43 extending in the left-right direction is provided on the right side wall of the lower mold body 46. The sliding groove 43 communicates with the relief groove 41, and the push plate 100 is slidably installed in the sliding groove 43. The push plate 100 can slide to the left to insert into the relief groove 41 and the discharge groove 44, pushing the cut waste material out of the lower mold body 46 through the discharge groove 44. A restoring elastic element 120 is connected between the push plate 100 and the groove wall of the sliding groove 43. The restoring elastic element 120 is a compression spring, which is used to drive the push plate 100 to slide to the right.

[0049] Reference Figure 7 and Figure 8 The depth of the clearance groove 41 is greater than the depth to which the cut piece 6 is inserted into the clearance groove 41. A button 110 is fixedly mounted on the upper surface of the lower mounting plate 47, and the button 110 is located in the clearance groove 41. The button 110 is electrically connected to the translation drive source 9. When a certain amount of waste material accumulates in the clearance groove 41, the cut piece 6 descends, and the waste material squeezes and triggers the button 110, thereby activating the translation drive source 9, which drives the push plate 100 to move, so as to periodically clean the waste material accumulated in the clearance groove 41.

[0050] Reference Figure 8 A sliding groove 45 extending in the front-to-back direction is provided on the rear side wall of the lower mold body 46, and the sliding groove 45 is connected to the sliding groove 43. A pusher 130 is slidably installed in the sliding groove 45 in the front-to-back direction. The left side of the end of the pusher 130 facing the pusher plate 100 is formed with an inclined push surface 131 by a chamfering process. The push surface 131 is inclined in a direction that is more inclined to the right as it moves forward. When the pusher 130 moves forward, the push surface 131 slides and abuts against the pusher plate 100, causing the pusher plate 100 to move to the left, pushing out the end of the waste material in the clearance groove 41, and then manually pulling out all the waste material.

[0051] Reference Figure 9The rear end of the pusher 130 extends through the sliding groove 45 for manual operation. A return elastic element 140 is connected between the pusher 130 and the groove wall of the sliding groove 45. The return elastic element 140 is a compression spring, which drives the pusher 130 to slide backward and reset.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
