[0032] The present disclosure provides a battery terminal stamping die, comprising a pre-stressing mechanism and a molding mechanism, wherein the pre-stressing mechanism comprises a pre-stressing upper die assembly and a pre-stressing lower die assembly, wherein the pre-stressing upper die assembly comprises a pre-stressing punch and a pre-stressing block, wherein the pre-stressing block is connected to the pre-stressing punch, wherein the pre-stressing block is used to be connected to a driving member, wherein the pre-stressing punch is provided with a pulling-up cavity, wherein the pre-stressing lower die assembly comprises a pre-stressing lower die and a pre-stressing ejector, wherein the pre-stressing lower die is provided with a pre-stressing cavity, wherein the pre-stressing lower die is arranged opposite to the pre-stressing punch, wherein the pre-stressing ejector is movably arranged on the pre-stressing lower die, wherein the pre-stressing ejector is used to eject a material from the pre-stressing lower die; wherein the molding mechanism is arranged adjacent to the pre-stressing mechanism, wherein the molding mechanism is used to stamp and mold the material after being stamped by the pre-stressing mechanism.
[0033] The battery terminal stamping die mentioned above has a pre-stressing punch with a lifting cavity, a pre-stressing lower die with a pre-stressing cavity, and the pre-stressing punch and the pre-stressing lower die are arranged opposite to each other. When the material is placed into the pre-stressing cavity of the pre-stressing lower die, the pre-stressing punch is driven downward by an external driving member, so that the pre-stressing upper die assembly and the pre-stressing lower die assembly are closed. At this time, one end of the material is deformed along the extension direction of the pre-stressing cavity under the extrusion of the pre-stressing punch, and at the same time, the end of the material abutting against the pre-stressing punch is deformed along the extension direction of the lifting cavity. Finally, the material after one stamping is formed by a forming mechanism. Specifically, by providing a lifting cavity on the pre-stressing punch, the material is squeezed and stretched toward both ends during pre-stressing, so that a product of a preset height can be formed with a thinner material, saving materials and reducing production costs.
[0034] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
[0035] like Figures 1 to 5As shown, a battery terminal stamping die 10 of an embodiment includes a pre-stressing mechanism 100 and a forming mechanism 200, wherein the pre-stressing mechanism 100 includes a pre-stressing upper die assembly 110 and a pre-stressing lower die assembly 120, wherein the pre-stressing upper die assembly 110 includes a pre-stressing punch 111 and a pre-stressing block 112, wherein the pre-stressing block 112 is connected to the pre-stressing punch 111, wherein the pre-stressing block 112 is used to be connected to a driving member, wherein the pre-stressing punch 111 is provided with a drawing cavity 111a, wherein the pre-stressing lower die assembly 120 includes a pre-stressing lower die 121 and a pre-stressing ejector 122, wherein the pre-stressing lower die 121 is provided with a pre-stressing cavity 121a, wherein the pre-stressing lower die 121 is arranged opposite to the pre-stressing punch 111, wherein the pre-stressing ejector 122 is movably arranged on the pre-stressing lower die 121, wherein the pre-stressing ejector 122 is used to eject the material from the pre-stressing lower die 121. Furthermore, the forming mechanism 200 is arranged adjacent to the pre-pressing mechanism 100, and the forming mechanism 200 is used to stamp and form the material after being stamped by the pre-pressing mechanism 100, so that the material is first stamped by the pre-pressing mechanism 100 and then stamped and formed into a final shape by the forming mechanism 200.
[0036] In this embodiment, the material is first placed in the pre-pressing cavity 121a of the pre-pressing lower die 121, and the external driving member drives the pre-pressing block 112 to drive the pre-pressing punch 111 to move downward, so that the material is pressed between the pre-pressing punch 111 and the pre-pressing lower die 121. Under the continuous force, the material is deformed along the extension direction of the pre-pressing cavity 121a, and because the end of the pre-pressing punch 111 that abuts the material is provided with a lifting cavity 111a, the end of the material that abuts the pre-pressing punch 111 is deformed along the extension direction of the lifting cavity 111a, and the material is squeezed and extended to both ends to better stretch and shape the material. Then, the material that has been punched once by the pre-pressing mechanism 100 is placed in the forming mechanism 200, and the forming mechanism 200 performs a second punching to form the material into the final shape. Specifically, by providing a drawing cavity 111a on the pre-pressing punch 111, the material can be squeezed towards both ends during pre-pressing. Compared with the flat design of the upper mold end face in traditional technology, the present application can better stretch materials of the same thickness, that is, thinner materials can be stretched to a preset height, thus saving materials and reducing production costs.
[0037] In the above-mentioned battery terminal stamping die 10, the pre-stressing punch 111 is provided with a lifting cavity 111a, and the pre-stressing lower die 121 is provided with a pre-stressing cavity 121a, and the pre-stressing punch 111 and the pre-stressing lower die 121 are arranged opposite to each other. When the material is placed into the pre-stressing cavity 121a of the pre-stressing lower die 121, the pre-stressing punch 111 is pressed downward under the drive of an external driving member, so that the pre-stressing upper die assembly 110 and the pre-stressing lower die assembly 120 are molded. At this time, one end of the material is deformed along the extension direction of the pre-stressing cavity 121a under the extrusion of the pre-stressing punch 111, and at the same time, the end of the material abutting against the pre-stressing punch 111 is deformed along the extension direction of the lifting cavity 111a. Finally, the material after one stamping is formed by the forming mechanism 200. Specifically, by providing a drawing cavity 111a on the pre-pressing punch 111, the material is squeezed and stretched at both ends during pre-pressing, so that a product of a preset height can be formed with a thinner material, saving materials and reducing production costs.
[0038] like Figure 2 As shown, in one embodiment, the cross section of the raised cavity 111a is circular. It can be understood that when the material contacts the pre-pressing upper die, under the continuous extrusion force, one end of the material deforms along the extension direction of the raised cavity 111a, that is, after one stamping is completed, the end face shape of the material is similar to the shape of the raised cavity 111a.
[0039] like Figure 2 As shown, in one embodiment, the elevating cavity 111a is opened in the middle of one end of the pre-pressing punch 111 adjacent to the pre-pressing lower die 121. It can be understood that the elevating cavity 111a is opened in the middle of the pre-pressing punch 111, so that the periphery of the material is deformed upward along the middle position when the material is extruded, so as to stretch the material.
[0040] In one embodiment, the pre-pressing lower die 121 is provided with a first movable cavity, and the pre-pressing ejector 122 is located in the first movable cavity. It can be understood that one end of the material is deformed along the extension direction of the pre-pressing cavity 121a, and the material directly abuts against the pre-pressing ejector 122. After a stamping is completed, the driving member drives the pre-pressing ejector 122 to move in the first movable cavity to eject the material out of the pre-pressing lower die 121.
[0041] like Figure 4 As shown, in one embodiment, the pre-pressing cavity 121a includes a placement cavity 1211 and a pressing cavity 1212, and the placement cavity 1211, the pressing cavity 1212 and the first active cavity are sequentially connected. It can be understood that the material is placed in the placement cavity 1211, and after the pressing action of the pre-pressing punch 111, the material is deformed along the extension direction of the pressing cavity 1212, and one end of the material directly extends into the first active cavity and abuts against the pre-pressing ejector 122.
[0042] like Figure 1 As shown in Figure 4, in one embodiment, the molding mechanism 200 includes a molding upper die punch 210 and a molding lower die assembly 220, and the molding lower die assembly 220 includes a molding lower die 221 and a molding ejector 222. The molding upper die punch 210 is used to be connected to the driving member, and the molding lower die 221 is provided with a molding cavity. The molding ejector 222 is movably arranged on the molding lower die 221, and the molding lower die 221 is used to eject the material from the molding lower die 221. In this embodiment, the material after a primary stamping by the pre-pressing mechanism 100 needs to be stamped twice by the molding mechanism 200, and the material is placed in the molding cavity. The driving member drives the molding upper die punch 210 to press down and abut against the material, so that the material is molded into the final shape, and finally the driving member drives the molding ejector 222 to eject the material from the molding lower die 221.
[0043] In one embodiment, the lower forming die 221 is provided with a second movable cavity, and the forming ejector 222 is located in the second movable cavity. It can be understood that under the extrusion of the upper forming die punch 210, one end of the material is deformed along the extension direction of the forming cavity until it abuts against the forming ejector 222 in the second movable cavity. After the secondary stamping is completed, the driving member drives the forming ejector 222 to eject the material out of the lower forming die 221.
[0044] like Figure 2 As shown, in one embodiment, one end of the upper die punch 210 adjacent to the lower die 221 is flat. It can be understood that the top of the material is elongated under the action of the drawing cavity 111a, so that one end of the material protrudes, and the protruding structure of the material is flattened by the upper die punch 210, so that the material is formed into the final desired shape.
[0045] like Figure 3 As shown, in one embodiment, a molding groove 222a is formed at one end of the molding ejector 222 adjacent to the molding upper die punch 210. It can be understood that the bottom of the material deforms along the extension direction of the molding cavity until it abuts against the molding ejector 222, and under the continuous pressing force, the bottom of the material is formed into a structure similar to the molding groove 222a.
[0046] The present application also provides a battery terminal production device, comprising the battery terminal stamping die 10 described in any of the above embodiments.
[0047] Compared with the prior art, the present invention has at least the following advantages:
[0048] In the above-mentioned battery terminal stamping die 10, the pre-stressing punch 111 is provided with a lifting cavity 111a, and the pre-stressing lower die 121 is provided with a pre-stressing cavity 121a, and the pre-stressing punch 111 and the pre-stressing lower die 121 are arranged opposite to each other. When the material is placed into the pre-stressing cavity 121a of the pre-stressing lower die 121, the pre-stressing punch 111 is pressed downward under the drive of an external driving member, so that the pre-stressing upper die assembly 110 and the pre-stressing lower die assembly 120 are molded. At this time, one end of the material is deformed along the extension direction of the pre-stressing cavity 121a under the extrusion of the pre-stressing punch 111, and at the same time, the end of the material abutting against the pre-stressing punch 111 is deformed along the extension direction of the lifting cavity 111a. Finally, the material after one stamping is formed by the forming mechanism 200. Specifically, by providing a drawing cavity 111a on the pre-pressing punch 111, the material is squeezed and stretched at both ends during pre-pressing, so that a product of a preset height can be formed with a thinner material, saving materials and reducing production costs.
[0049] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent.
