[0047] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0048] This embodiment provides a stamping die for a battery cover plate, which can improve production efficiency, save costs, and improve the safety of operators.
[0049] Such as Figures 1-4As shown in the figure, the stamping die for the battery cover plate mainly includes a blanking ring 100, a lower die cutting edge 200, a drawing female die 300, a lower die core 400, and a drawing punch 500. Among them, the blanking ring 100 is arranged opposite to the lower die cutting edge 200, and the blanking ring 100 and the lower die cutting edge 200 can jointly cut the incoming material to form a blanking sheet. The drawing female die 300 is arranged inside the lower die cutting edge 200, and the inner wall of the drawing female die 300 has a first step portion 310. One end of the lower die core 400 passes through the drawing female die 300 and supports the blanking sheet. The drawing punch 500 passes through the blanking ring 100, and one end of the drawing punch 500 is used to pass through the blanking ring 100 and punch the blanking sheet, so that the blanking sheet jointly forms a product 10 on the first step portion 310 and the lower die core 400. Exemplarily, the product 10 is the battery cover plate, and the battery cover plate can be a top cover or a bottom cover.
[0050] Based on the above design, in this embodiment, the blanking of the incoming material can be achieved through the settings of the blanking ring 100 and the lower die cutting edge 200. Then, through the combined action of the drawing punch 500 and the drawing female die 300, the blanking sheet is punched, so that the blanking sheet can jointly form a top cover or a bottom cover on the first step portion 310 and the lower die core 400. At this time, the lower die core 400 supports the blanking sheet during the entire stamping process. Through the settings of the blanking ring 100, the lower die cutting edge 200, the drawing female die 300, the lower die core 400, and the drawing punch 500, the stamping die for the battery cover plate in this embodiment can simultaneously achieve the steps of blanking and punching, thus eliminating the need for the operator in the prior art to manually transfer the blanking sheet to the stamping die for punching, improving work efficiency, saving time and effort, and reducing costs. At the same time, it also reduces the danger of the operator in the prior art manually transferring the blanking sheet for punching, improving safety performance.
[0051] In addition, the manufacturing process of the battery cover plate in this embodiment is to cut the material first and then punch it. That is to say, first, the incoming material is cut by the blanking ring 100 and the lower die cutting edge 200 to form a blanking sheet. Then, the blanking sheet is punched by the drawing female die 300, the lower die core 400, and the drawing punch 500 to form the battery cover plate, which can make the burrs of the battery cover plate face the inside of the battery cover plate, thus meeting the requirements for the product 10 with requirements for the burr orientation. At the same time, since the prior art is to stretch first and then cut, in the process of cutting, the phenomenon of an outer step will appear at the edge of the battery cover plate, thus affecting the yield of the product 10. The method of cutting the material first and then punching and stretching in this embodiment can well solve this problem. Specifically, in this embodiment, when the phenomenon of an outer step appears at the edge during the cutting process, the outer step can be eliminated through the subsequent punching and stretching steps, thus solving the above problem.
[0052] It can be understood that the stretching punch 500 in this embodiment is in clearance fit with the blanking ring 100, and the blanking ring 100 is in clearance fit with the lower die cutting edge 200, thereby facilitating the opening and closing actions of the battery cover stamping die.
[0053] As Figures 2-3 shown, in this embodiment, a second step portion 510 is provided at one end of the stretching punch 500 facing the stretching female die 300, and the second step portion 510 is correspondingly arranged with the first step portion 310, so that the second step portion 510 can stamp and form part of the blanking sheet on the first step portion 310. Through the stamping and stretching of the blanking sheet by the first step portion 310 and the second step portion 510, the bent portion of the battery cover is formed, and the bottom of the battery cover is directly formed by stamping with the stretching punch 500 and the lower die core 400.
[0054] As Figures 2-3 shown, in this embodiment, the stretching female die 300 has a first inner side wall 320 and a second inner side wall 330. One end of the first step portion 310 is connected to the first inner side wall 320, and the other end is connected to the second inner side wall 330. The lower die core 400 is in clearance fit with the second inner side wall 330. Thus, after stamping, it is beneficial for the lower die core 400 to eject the battery cover, facilitating the discharging of the product 10 and improving work efficiency.
[0055] A preset gap B is provided between the outer wall of the stretching punch 500 and the first inner side wall 320. The setting of this preset gap B is beneficial for forming the edge of the battery cover. At the same time, the outer wall of the stretching punch 500 and the first inner side wall 320 of the stretching female die 300 are matched with a negative angle of 1 degree, thereby meeting the production requirements of the product 10 and improving the qualification rate.
[0056] As Figures 2-3 shown, in this embodiment, a third step portion 110 is further provided on the outer wall of the blanking ring 100, and the third step portion 110 is configured to limit the movement stroke of the blanking ring 100. Thus, the phenomenon that the blanking ring 100 collides with the lower die cutting edge 200 due to excessive movement stroke is avoided, improving safety and reliability.
[0057] As Figures 2-3 shown, in this embodiment, a fourth step portion 340 is further provided on the outer wall of the stretching female die 300, and a fifth step portion 210 is provided on the inner wall of the lower die cutting edge 200. The fifth step portion 210 is configured to limit the movement stroke of the stretching female die 300 through the fourth step portion 340. Through the setting of the fourth step portion 340 and the fifth step portion 210, the movement of the stretching female die 300 can be restricted, avoiding violent collision between the stretching female die 300 and the lower die cutting edge 200.
[0058] Please continue to refer to Figures 2-3, on the outer wall of the lower die core 400 in this embodiment, a sixth step portion 410 is provided, and the sixth step portion 410 is configured to limit the movement stroke of the lower die core 400. In this way, when the battery cover plate is punched, during the process of the lower die core 400 ejecting the battery cover plate, the sixth step portion 410 can limit the movement stroke of the lower die core 400, avoiding the lower die core 400 from disengaging from the drawing die 300, and improving the stability and reliability of the battery cover plate stamping die.
[0059] As Figure 1 , Figures 5-6 shown, in this embodiment, a first groove 520 is further provided on the outer wall of the drawing punch 500. The battery cover plate stamping die further includes an upper template 600 and a first fixing member 610. The first fixing member 610 fixes the drawing punch 500 to the upper template 600 through the first groove 520. A second groove 220 is further provided on the outer wall of the lower die cutting edge 200. The battery cover plate stamping die further includes a lower template 700 and a second fixing member 710. The second fixing member 710 fixes the lower die cutting edge 200 to the lower template 700 through the second groove 220.
[0060] Through the settings of the first groove 520, the first fixing member 610 and the upper template 600, the stability and reliability of the connection between the drawing punch 500 and the upper template 600 can be improved, avoiding the drawing punch 500 from falling during the working process. Through the settings of the second groove 220, the second fixing member 710 and the lower template 700, the stability and reliability of the connection between the lower die cutting edge 200 and the lower template 700 can be improved, avoiding the lower die cutting edge 200 from bouncing and disengaging during the working process.
[0061] Exemplarily, the first fixing member 610 and the second fixing member 710 in this embodiment can both be set as conventional components such as screws or bolts, which are easy to obtain and have low costs.
[0062] As Figures 1-2 shown, a vent hole 530 is further provided inside the drawing punch 500 in this embodiment, and the vent hole 530 penetrates through opposite ends of the drawing punch 500. Through the setting of the vent hole 530, air in the battery cover plate stamping die can be discharged in time during the stamping process, avoiding adverse effects of the gas on the stamping of the product 10 and improving the yield rate of the product 10.
[0063] Optionally, the vent hole 530 in this embodiment is coaxially arranged with the drawing punch 500 to improve the exhaust efficiency.
[0064] As Figures 5-6As shown, in this embodiment, the stamping die for the battery cover plate further includes a driving component 800. The driving end of the driving component 800 is drivingly connected to the end of the lower die core 400 away from the blanking ring 100. By providing the driving component 800, the ejection action of the lower die core 400 can be realized, so that the stamped product 10 can be ejected, and thus the discharging process can be successfully completed.
[0065] Exemplarily, the driving component 800 in this embodiment can be set as a cylinder.
