Description

Technical Field

[0001] This application relates to the field of punching equipment technology, and more specifically, to a punching apparatus for copper busbar production. Background Technology

[0002] In the electrical industry, copper busbars are key conductive components, and the quality of their punching directly affects the performance of products such as busbars and switchgear. Therefore, most companies use punching equipment to punch copper busbars. However, the punching spacing of traditional punching equipment is usually achieved by disassembling and replacing molds, which makes it impossible to adapt to the copper busbar hole spacing requirements of different specifications of electrical cabinets in a short time. This not only increases production costs but also results in low punching efficiency. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a punching device for copper busbar production, including a worktable. A fixed frame and a movable frame are respectively arranged on the left and right sides of the top of the worktable. A first punch for punching one side of the copper busbar is vertically movable inside the fixed frame, and a second punch for punching the other side of the copper busbar is vertically movable inside the movable frame. A lead screw linear module is arranged on the side of the fixed frame, and the lead screw linear module is transversely connected to the movable frame. The lead screw linear module moves simultaneously within both the fixed frame and the movable frame, and also drives the movable frame, along with the second punch, to move along the side of the fixed frame, thereby changing the punching distance between the first punch and the second punch.

[0004] Preferably, a first lifting rod is provided between the fixed frame and the first punch, and the first lifting rod is hinged inside the fixed frame, and the first punch is located at the bottom of the first lifting rod. A first cylinder is provided between the fixed frame and the first lifting rod, and the first cylinder is obliquely located at the back of the top of the fixed frame. The first cylinder is driven to the first lifting rod and drives the first lifting rod to move the first punch vertically inside the fixed frame.

[0005] Preferably, a first stamping platform is formed at the bottom of the front side of the fixing frame, and a copper plate is placed on the top of the first stamping platform. The first punch is vertically located above the first stamping platform. A first positioning hole is vertically formed on the top of the first stamping platform to fit into the first punch. The first positioning hole passes through the first stamping platform and the fixing frame respectively.

[0006] Preferably, a second lifting rod is provided between the movable frame and the second punch, and the second lifting rod is hinged inside the movable frame. The second lifting rod moves synchronously with the movable frame. The second punch is located at the bottom of the second lifting rod, and the second punch moves synchronously with the movable frame through the second lifting rod. A second cylinder is provided between the movable frame and the second lifting rod, and the second cylinder is obliquely located at the back of the top of the movable frame. The second cylinder is driven by the second lifting rod and drives the second lifting rod to move the second punch vertically inside the movable frame.

[0007] Preferably, a second stamping platform is formed at the bottom of the front side of the movable frame, and a copper busbar is placed on the top of the second stamping platform. The second punch is vertically located above the second stamping platform. A second positioning hole is vertically formed on the top of the second stamping platform to cooperate with the second punch. The second positioning hole passes through the second stamping platform and the movable frame respectively.

[0008] Preferably, the top of the workbench is formed with a placement platform for placing copper busbars, and the placement platform is laterally located on the front side of the fixed frame and the movable frame. A limiting groove is laterally formed on the back side of the placement platform, and a limiting slider is laterally formed on the front side of the movable frame. The limiting slider is inserted into the limiting groove, and there is a sliding engagement between the limiting slider and the limiting groove.

[0009] In summary, the beneficial effects of this application are as follows:

[0010] When adjusting the punching spacing of the copper busbar, the operator only needs to start the lead screw linear module. When the lead screw linear module is working, it will drive the moving frame and the second punch to move laterally on the side of the fixed frame until the spacing between the first punch and the second punch is consistent with the required hole spacing. Then, the operator places the copper busbar under the first punch and the second punch and drives the first punch and the second punch to move towards the copper busbar at the same time until the first punch and the second punch contact the top of the copper busbar and punch the copper busbar at the same time in multiple positions. This embodiment can adjust the hole spacing of the copper busbar without disassembling and changing the mold. This not only reduces the production cost, but also can adapt to the punching requirements of different hole spacings. It effectively solves the technical problem that the punching spacing of traditional punching devices is usually achieved by disassembling and changing the mold, which makes it impossible to adapt to the copper busbar hole spacing requirements of different specifications of electrical cabinets in a short time. This not only increases the production cost, but also results in low punching efficiency. Attached Figure Description

[0020] A punching device for copper busbar production, see [link / reference] Figures 1 to 4The system includes a workbench 1, with a fixed frame 2 and a movable frame 3 respectively installed on the left and right sides of the top of the workbench 1. A first punch 4 for punching one side of a copper busbar is vertically movable inside the fixed frame 2, and a second punch 5 for punching the other side of the copper busbar is vertically movable inside the movable frame 3. A lead screw linear module 6 is installed on the side of the fixed frame 2, and the lead screw linear module 6 is horizontally connected to the movable frame 3 through the fixed frame 2. The lead screw linear module 6 moves within both the fixed frame 2 and the movable frame 3, and also drives the movable frame 3, along with the second punch 5, to the fixed frame 2. Lateral movement alters the punching distance between the first punch 4 and the second punch 5. In this embodiment, when punching a copper busbar is required, the operator simply places the copper busbar horizontally below the first punch 4 and the second punch 5, then drives the first punch 4 and the second punch 5 to move simultaneously toward the copper busbar until they contact the top of the copper busbar and simultaneously punch it. Multi-station punching effectively improves punching efficiency. When adjusting the punching distance of the copper busbar, the operator simply starts the screw motor before placing the copper busbar below the first punch 4 and the second punch 5. The linear screw module 6 starts working. When the linear screw module 6 works, it drives the moving frame 3, along with the second punch 5, to move laterally to the side of the fixed frame 2 until the distance between the first punch 4 and the second punch 5 matches the required hole spacing. Then, the operator places the copper busbar and repeats the above punching steps to punch the copper busbar. This allows the hole spacing of the copper busbar to be adjusted without disassembling and changing the mold, which not only reduces production costs but also adapts to punching requirements with different hole spacings. It effectively solves the problem that the punching spacing of traditional punching devices is usually achieved by disassembling and changing the mold. The inability to adapt to the copper busbar hole spacing requirements of different specifications of electrical cabinets in a short time not only increases production costs but also causes technical problems such as low punching efficiency. In addition, in this embodiment, multiple first slide rail assemblies 7 are provided between the movable frame 3 and the worktable 1, and the first slide rail assemblies 7 are respectively located laterally on the front and rear sides of the top of the worktable 1. The movable frame 3 and the first slide rail assemblies 7 move in the same direction. By providing the first slide rail assemblies 7, the movable frame 3 drives the second punch 5 to move laterally on the top of the worktable 1 to change the punching spacing more smoothly and without positional deviation, which effectively improves the stability of this embodiment.

[0021] A first lifting rod 8 is provided between the fixed frame 2 and the first punch 4, and the first lifting rod 8 is hinged inside the fixed frame 2. The first punch 4 is located at the bottom of the first lifting rod 8. A first cylinder 9 is provided between the fixed frame 2 and the first lifting rod 8, and the first cylinder 9 is obliquely located at the back of the top of the fixed frame 2. The first cylinder 9 is driven by the first lifting rod 8, and the first cylinder 9 drives the first lifting rod 8 to move the first punch 4 vertically inside the fixed frame 2. In this embodiment, because the first lifting rod 8 is hinged inside the fixed frame 2, when the first cylinder 9 drives the first lifting rod 8 to move, it will drive the first punch 4 to move vertically under the action of the lever principle. A punch 4 moves vertically inside the fixed frame 2 to punch a hole on one side of the copper busbar. The cooperation between the above structures effectively improves the punching efficiency of this embodiment. In addition, in this embodiment, a second slide rail assembly (not shown in the figure) is provided between the first punch 4 and the fixed frame 2. The second slide rail assembly is vertically located on the back side inside the fixed frame 2, and the first punch 4 and the second slide rail assembly move in the same direction. By providing the second slide rail assembly, the first punch 4 will not be displaced when it moves inside the fixed frame 2, thereby affecting the normal punching action of the first punch 4 on the copper busbar and effectively improving the stability of this embodiment.

[0022] The fixing frame 2 has a first stamping platform 10 formed at the bottom of its front side, and the copper busbar is placed on top of the first stamping platform 10. The first punch 4 is vertically positioned above the first stamping platform 10. The top of the first stamping platform 10 has a first positioning punch 11 that is inserted and fitted with the first punch 4. The first positioning punch 11 passes through the first stamping platform 10 and the fixing frame 2 respectively. In this embodiment, when it is necessary to punch the copper busbar, the operator only needs to place the copper busbar on top of the first stamping platform 10. At this time, the copper busbar will cover the top of the first positioning punch 11, and the first punch 4 is positioned above the copper busbar. Then, the first cylinder 9 drives the first lifting rod 8 together with the first punch 4 to punch the copper busbar. During this process, the scrap material that is punched off will fall into the first positioning punch 11. Through the cooperation between the above structures, the automation level and operational reliability of this embodiment are effectively improved.

[0023] A second lifting rod 12 is provided between the movable frame 3 and the second punch 5, and the second lifting rod 12 is hinged inside the movable frame 3. The second lifting rod 12 moves synchronously with the movable frame 3. The second punch 5 is located at the bottom of the second lifting rod 12, and the second punch 5 moves synchronously with the movable frame 3 via the second lifting rod 12. A second cylinder 13 is provided between the movable frame 3 and the second lifting rod 12, and the second cylinder 13 is obliquely located at the back of the top of the movable frame 3. The second cylinder 13 is driven by the second lifting rod 12, and the second cylinder 13 drives the second lifting rod 12 to move the second punch 5 vertically inside the movable frame 3. In this embodiment, because the second lifting rod 12 is hinged inside the fixed frame 2, the second cylinder... When the second lifting rod 12 moves, it will drive the second punch 5 to move vertically inside the moving frame 3 under the action of the lever principle, thereby realizing the punching of the other side of the copper busbar. Through the cooperation between the above structures, the punching efficiency of this embodiment is further improved. In addition, in this embodiment, a third slide rail assembly (not shown in the figure) is provided between the second punch 5 and the moving frame 3. The third slide rail assembly is vertically located on the back side inside the moving frame 3, and the second punch 5 and the third slide rail assembly move in the same direction. By providing the third slide rail assembly, the second punch 5 will not be offset when it moves inside the moving frame 3, thereby affecting the normal punching action of the second punch 5 on the copper busbar, and further improving the stability of this embodiment.

[0024] The movable frame 3 has a second stamping platform 14 formed at its bottom front side, and a copper busbar is placed on top of the second stamping platform 14. A second punch 5 is vertically positioned above the second stamping platform 14. A second positioning hole 15 is vertically formed on the top of the second stamping platform 14 to mate with the second punch 5. The second positioning hole 15 penetrates both the second stamping platform 14 and the movable frame 3. In this embodiment, the operator places the copper busbar simultaneously on top of both the first stamping platform 10 and the second stamping platform 14, at which point the copper busbar will simultaneously cover the first positioning hole 15. The top of the first positioning punch 11 and the top of the second positioning punch 15 are positioned above the copper busbar. Then, the first cylinder 9 drives the first lifting rod 8 together with the first punch 4 and the second cylinder 13 drives the second lifting rod 12 together with the second punch 5 to punch the copper busbar simultaneously, thereby realizing dual-station punching. During this process, the scrap material that is punched down will fall into the first positioning punch 11 and the second positioning punch 15 respectively. Through the cooperation between the above structures, the automation level and operational reliability of this embodiment are further improved.

[0025] The top of the workbench 1 is formed with a placement platform 16 for placing copper busbars, and the placement platform 16 is laterally located on the front side of the fixed frame 2 and the movable frame 3. The back of the placement platform 16 is laterally formed with a limiting groove (not shown in the figure). The front side of the movable frame 3 is laterally formed with a limiting slider 17, and the limiting slider 17 is inserted into the limiting groove. The limiting slider 17 and the limiting groove are in sliding cooperation. In this embodiment, when the copper busbar is placed on the top of the first stamping table 10 and the top of the second stamping table 14, the copper busbar will be simultaneously located on the top of the placement platform 16. The placement platform 16 can provide support for the copper busbar. Furthermore, the cooperation between the limiting slider 17 and the limiting groove can further improve the stability when the movable frame 3 drives the second punch 5 to move laterally on the top of the workbench 1 to change the punching spacing.

[0026] The workbench 1 has a discharge pipe 18 formed inside for guiding the stamping waste in the first positioning punch 11 and the second positioning punch 15.
