[0021] Please refer to Figures 1-5, A punching die for the production of a PC bracket of a battery collection busbar CCS of the present utility model includes a material discharging base 1, a supporting tool holder 2, and a blade fixing bracket 3 installed in sequence. The material discharging base 1 includes a plurality of material discharging grooves, and the plurality of material discharging grooves include at least a top notch 11 and a side notch 12 extending to the side wall; the supporting tool holder 2 is used to support the blade fixing bracket 3 and includes a material discharging port opposite to the material discharging groove; the blade fixing bracket 3 includes an outer fixing bracket 31 and an inner fixing bracket 32. The outer fixing bracket 31 is installed with an outer blade 4, and the inner fixing bracket 32 is fixed with a plurality of punching blades 5. The cutting edges of the outer blade 4 and the punching blades 5 face upward, and the middle of the punching blade 5 is hollowed out and communicated with the material discharging port and the material discharging groove; the punching die provided by the present utility model is mainly used for the processing of a PC bracket 6 for fixing a new energy battery collection busbar CCS module. Since the PC bracket 6 needs to collect data of multiple batteries, a plurality of holes need to be opened in the middle for collecting battery data. The traditional processing technology first requires different metal molds for different battery modules and different permutations and combinations, with high mold opening costs, and at the same time, it is difficult to discharge the waste after stamping; the blade fixing bracket 3 provided by the present application first includes an outer fixing bracket 31 and an inner fixing bracket 32, and the outer fixing bracket 31 and the inner fixing bracket 32 are detachably connected, so that when changing the type of the PC bracket 6 to be processed, it is possible to realize the processing type only by changing the type of the inner fixing bracket 32; and, the material discharging base 1 includes a plurality of material discharging grooves, and the plurality of material discharging grooves include at least a top notch 11 and a side notch 12 extending to the side wall. The middle of the punching blade 5 is hollowed out and communicated with the material discharging port and the material discharging groove, so that the PC waste after punching can directly fall into the material discharging port and the material discharging groove and be discharged from the side notch 12, avoiding waste accumulation.

[0022] In one embodiment, the side notch 12 may have a slope structure inclined from the middle to the side wall direction, which is beneficial for the waste to directly slide out through the slope structure, further ensuring the discharge efficiency of the waste.

[0023] In one embodiment, there is an installation gap between the outer fixing bracket 31 and the inner fixing bracket 32. The outer blade 4 is installed in the installation gap, and the outer fixing bracket 31 and the inner fixing bracket 32 are detachably connected; the outer blade 4 is used to process the basic outer contour of the PC bracket 6. The installation gap is convenient for the quick disassembly and assembly of the inner fixing bracket 32 and can be used to install the outer blade 4.

[0024] In one embodiment, the internal fixing bracket 32 is provided with a plurality of blade fixing holes 321, and the plurality of blade fixing holes 321 are located at the same position as the discharge port. A plurality of punching blades 5 are installed in the plurality of blade fixing holes 321; the plurality of blade fixing holes 321 correspond to a plurality of holes of the PC bracket 6 for installing batteries. The blade fixing holes 321 are punched by installing the punching blades 5. The fact that the blade fixing holes 321 and the discharge port are located at the same position can ensure the discharge of the waste after punching. Here, the position and shape of the blade fixing holes 321 can be customized according to the shape required by the user.

[0025] In one embodiment, the plurality of punching blades 5 include at least two or more different blade edge shapes; in this embodiment, the plurality of punching blades 5 may include a square blade edge and a quasi-elliptical blade edge, or may include a circular blade edge.

[0026] In one embodiment, the punching blade 5 includes a blade fixing base 51 and a blade edge. The blade fixing base 51 is adapted to the shape of the blade fixing hole 321, and the blade fixing base 51 is detachably connected to the blade fixing hole 321; here, the detachably connected blade fixing base 51 and the blade fixing hole 321 enable the punching blade 5 to be detached and replaced independently of the internal fixing bracket 32. Therefore, when processing a PC bracket 6 with the same hole processing position but a changed hole shape, different processing can be achieved only by replacing the punching blade 5, further reducing the cost of replacing the mold.

[0027] In one embodiment, the blade edge includes a supporting portion 52, a punching portion 53, and a mounting portion 54. The supporting portion 52 is located between the mounting portion 54 and the punching portion 53. The width of the supporting portion 52 is greater than the widths of the punching portion 53 and the mounting portion 54. The mounting portion 54 is installed in the blade fixing base 51, and the punching portion 53 is stuck outside the blade fixing base 51 through the supporting portion 52 for punching.

[0028] In one embodiment, the supporting portion 52 is provided with a first positioning groove 56, and a second positioning groove is provided at the relative position of the blade fixing base 51 and the positioning groove. The first positioning groove 56 and the second positioning groove are adapted to the positioning posts of the workpiece to be processed, so as to ensure the accuracy of the punching guaranteed processing position.

[0029] The blades described herein include ordinary blades, laser blades, and engraving knives.

[0030] The advantages of the present utility model are as follows:

[0031] The detachably connected outer fixing bracket and inner fixing bracket enable the type of the inner fixing bracket to be replaced according to the type and shape of the workpiece to be processed, which can greatly reduce the cost of replacing the mold. At the same time, the discharge groove includes at least a top notch and a side notch extending to the side wall, which can ensure the timely discharge of waste and avoid the accumulation of waste affecting processing.

[0032] The above are only several specific embodiments of the present utility model disclosed, but the present utility model is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
