Description

Technical Field

[0001] This utility model belongs to the field of copper busbar bending technology, and in particular relates to a copper busbar bending mold. Background Technology

[0002] A copper busbar bending die is a tool specifically designed for bending copper busbar materials. Its main function is to bend the copper busbar into the required angle and shape according to design requirements. This type of die usually consists of multiple structural parts, including a base, upper die, lower die, bending groove, guide system, clamping device, drive device, and safety device. The die base provides support for the entire die, while the upper and lower dies are the core components for bending the copper busbar. The upper die applies bending force, and the lower die provides the bending groove.

[0003] Existing copper busbar bending dies still have some problems in use. For example, traditional bending machines usually require adjustment of the depth of the upper and lower dies during the copper busbar bending process. Although most existing bending machines have depth adjustment functions, they cannot achieve synchronous adjustment of the depth of the upper and lower dies. This forces operators to rely on precise data support during the adjustment process and may need to make multiple adjustments to ensure accuracy. However, due to the complexity and cumbersome operation of the adjustment process, adjustment errors are prone to occur, which directly affects the accuracy and quality of the processing. In addition, due to the lack of a synchronous adjustment mechanism, inconsistencies in the adjustment process may lead to unstable copper busbar bending results, further reducing production efficiency and increasing the workload of manual operation.

[0004] To address these issues, we provide a copper busbar bending die. Utility Model Content

[0005] The purpose of this utility model is to provide a copper busbar bending die, which solves the problem that it is inconvenient to synchronously and accurately adjust the depth of the upper and lower dies in the existing copper busbar bending dies by cooperating with the adjustment component and the synchronization component.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a copper busbar bending die, comprising a base plate, a forming seat fixedly connected to the top of the base plate, lower die seats fixedly connected to both sides of the top of the base plate, and an upper die seat slidably connected to the bottom of the forming seat; an adjustment assembly is provided in the inner cavity of the forming seat, the adjustment assembly comprising a lead screw movably connected to one side of the inner cavity of the forming seat, a threaded sleeve threadedly connected to the surface of the lead screw, a base fixedly connected to one side of the threaded sleeve, and a pressure seat slidably connected to the bottom of the upper die seat, the adjustment assembly being used to synchronously adjust the height of the base and the pressure seat; a synchronization assembly is provided in the inner cavity of the forming seat, the synchronization assembly comprising a slide bar fixedly connected to both sides of the surface of the lead screw, a drive bevel gear slidably connected to the surface of the slide bar, a limiting plate fixedly connected to one side of the upper die seat, and guide angles fixedly connected to both sides of the bottom of the limiting plate, the synchronization assembly being used to ensure that the upper die seat and the pressure seat move synchronously.

[0008] The present invention is further configured such that a rotating rod is movably connected to the inner cavity of the upper mold base, and a driven bevel gear is fixedly connected to one end of the rotating rod, wherein the driving bevel gear meshes with the driven bevel gear.

[0009] The present invention is further configured such that a cam is fixedly connected to the surface of the rotating rod, and the surface of the cam is in contact with the top of the pressure seat.

[0010] The present invention is further configured such that springs are fixedly connected to both sides of the bottom of the upper mold base, and reset plates are fixedly connected to the top of both sides of the pressure base, with one end of the spring fixedly connected to the bottom of the reset plate.

[0011] The present invention is further configured such that a trapezoidal groove is provided at the top of the inner part of the active bevel gear, and the guide angle surface is movably connected to the inner cavity of the trapezoidal groove.

[0012] The present invention is further configured such that a cylinder is fixedly connected to the top of the molding seat, the free end of the cylinder is fixedly connected to the top of the upper mold seat, a motor is fixedly connected to one side of the top of the molding seat, and the output end of the motor is fixedly connected to one end of the lead screw.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model effectively solves the problem that traditional copper busbar bending dies cannot synchronously adjust the depth of the upper and lower dies by setting up adjustment components and synchronization components. The lead screw and threaded sleeve in the adjustment component can accurately control the height of the base. At the same time, the synchronization component ensures that the upper die seat and the pressure seat move synchronously through the linkage of the active bevel gear, the driven bevel gear and the guide angle, avoiding the tedious operation of repeated manual adjustment.

Detailed Implementation

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0026] Please see Figures 1-5 This utility model is a copper busbar bending die, including a base plate 1, a forming seat 2 fixedly connected to the top of the base plate 1, a controller fixedly connected to one side of the forming seat 2 for controlling a motor 20 and a cylinder 19, lower die seats 3 fixedly connected to both sides of the top of the base plate 1, the lower die seats 3 and the base 7 forming the entire lower die, while the upper die seats 4 and the pressure seat 8 forming the entire upper die, so as to facilitate bending and forming of the copper busbar. The bottom of the forming seat 2 is slidably connected to the upper die seat 4; the bottom of the upper die seat 4 has a slot, the inner cavity of the slot is slidably connected to the surface of the pressure seat 8, and the inner cavity of the forming seat 2 is provided with an adjustment component, the adjustment component including a movable... A lead screw 5 is movably connected to one side of the inner cavity of the forming base 2. A slide rod is fixedly connected to the other side of the inner cavity of the forming base 2. One side of the slide sleeve slidably connected to the surface of the slide rod is fixedly connected to one side of the base 7 for limiting and supporting the base 7. A threaded sleeve 6 is threadedly connected to the surface of the lead screw 5. Guide blocks are fixedly connected to both sides of the inner cavity of the forming base 2. One side of the guide block is slidably connected to the threaded sleeve 6 and one side of the slide sleeve to limit the slide sleeve and the threaded sleeve 6. A base 7 is fixedly connected to one side of the threaded sleeve 6. The base 7 rises and falls between the lower die base 3 to adjust the bending depth of the copper busbar. It is also slidably connected to the bottom of the upper die base 4. The pressure seat 8 is used to synchronously adjust the height of the base 7 and the pressure seat 8 via an adjustment component; the inner cavity of the forming seat 2 is provided with a synchronization component, which includes slide bars 9 fixedly connected to both sides of the surface of the lead screw 5, and a driving bevel gear 10 slidably connected to the surface of the slide bars 9. The slide bars 9 enable the driving bevel gear 10 to be driven to rotate by the lead screw 5, and a self-locking shaft is provided between the inner cavity of the driving bevel gear 10 and the surface of the lead screw 5. Through the cooperation of the guide angle 12, the position of the driving bevel gear 10 is limited, so that the driving bevel gear 10 and the driven bevel gear 14 are always meshed, and it is fixedly connected to the upper mold base. The limiting plate 11 on one side of the screw 5 has a circular hole in its inner cavity, so that the slide bar 9 on the surface of the screw 5 does not contact the limiting plate 11 and does not affect the normal movement of the active bevel gear 10. The guide angle 12 is fixedly connected to the bottom of the limiting plate 11 on both sides. The guide angle 12 is engaged with the inside of the active bevel gear 10 and is movably connected. It can limit the active bevel gear 10 without affecting its rotation. The synchronization component is used to ensure that the upper mold base 4 and the pressure base 8 move synchronously. The bottom of the pressure base 8 can provide the required bending force, and the pressure base 7 can open the required bending groove to complete the bending work. Example 2

[0027] Please see Figures 1-5Based on Embodiment 1, a rotating rod 13 is movably connected to the inner cavity of the upper mold base 4. A driven bevel gear 14 is fixedly connected to one end of the rotating rod 13, and the driven bevel gear 14 is fixedly connected to the end of the rotating rod 13 extending into the inner cavity of the forming seat 2. The driving bevel gear 10 meshes with the driven bevel gear 14. A cam 15 is fixedly connected to the surface of the rotating rod 13, and the surface of the cam 15 is in contact with the top of the pressure seat 8. By rotating the rotating rod 13, the cam 15 can be rotated, thereby pressing the pressure seat 8, which adjusts the height of the pressure seat 8. Furthermore, the rotation of the lead screw 5 drives the threaded sleeve 6 to move, which enables the base 7 to adjust its height synchronously, thereby synchronously adjusting the bending depth. Springs 16 are fixedly connected to both sides of the bottom of the upper mold base 4, and reset plates 17 are fixedly connected to the top of both sides of the pressure seat 8. The function of the springs 16 and the reset plates 17 is to drive the pressure seat 8 to reset. All are fixedly connected to a moving strip, the surface of which is slidably connected to one side of the reset plate 17 to limit the pressure seat 8 and the reset plate 17. One end of the spring 16 is fixedly connected to the bottom of the reset plate 17. A trapezoidal groove 18 is opened at the top of the active bevel gear 10. The inner cavity of the trapezoidal groove 18 is consistent with the shape of the guide angle 12 to limit the active bevel gear 10. The surface of the guide angle 12 is movably connected to the inner cavity of the trapezoidal groove 18. A cylinder 19 is fixedly connected to the top of the forming seat 2. The free end of the cylinder 19 is fixedly connected to the top of the upper mold seat 4. A motor 20 is fixedly connected to one side of the top of the forming seat 2. The output end of the motor 20 is fixedly connected to one end of the lead screw 5. An extension groove is opened in the inner cavity of the lower mold seat 3. The inner cavity of the extension groove passes through the inner cavity of the lower mold seat 3, but the groove opening is small and the copper busbar is made of rigid material, so it will not affect the bending. The inner cavity of the extension groove extends to the inner cavity of the forming seat 2. The surface of the threaded sleeve 6 is slidably connected to the inner cavity of the extension groove.

[0028] The working principle of this utility model is as follows: First, the motor 20 is started. The output end of the motor 20 drives the lead screw 5 to rotate. The threaded sleeve 6 on the surface of the lead screw 5 moves accordingly, thereby driving the base 7, which is fixedly connected to it, to slide up and down in the inner cavity of the molding seat 2, thereby adjusting the height of the base 7. At the same time, the slide bar 9 on the surface of the lead screw 5 drives the active bevel gear 10 to slide and rotate on the slide bar 9. The active bevel gear 10 drives the rotating rod 13 to rotate through the driven bevel gear 14 that meshes with it. The cam 15 on the surface of the rotating rod 13 rotates accordingly and applies pressure to the pressure seat 8, causing the pressure seat 8 to slide at the bottom inside the upper mold seat 4.

[0029] Meanwhile, the trapezoidal groove 18 at the top of the active bevel gear 10 and the guide angle 12 work together to ensure the precise sliding of the active bevel gear 10. The connection between the guide angle 12 and the limiting plate 11 ensures the stable operation of the synchronization component. Under the action of the springs 16 on both sides of the bottom of the upper die base 4 and the reset plates 17 on both sides of the top of the pressure base 8, the pressure base 8 can be flexibly reset. The cylinder 19 provides auxiliary driving force through the connection between its free end and the upper die base 4, ensuring the smooth movement of the upper die base 4. The extension groove in the inner cavity of the lower die base 3 provides sliding space for the threaded sleeve 6, further ensuring the stable adjustment of the base 7. Through the synergistic effect of the above-mentioned adjustment component and synchronization component, the synchronous movement of the upper die base 4 and the pressure base 8 is realized, ensuring the precise synchronous adjustment of the depth of the upper and lower dies during the copper busbar bending process. This avoids the tedious operation of repeated manual adjustments, significantly improves the adjustment accuracy and production efficiency, and reduces the workload of operators.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. 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 above 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.
