Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a stamping die for an aluminum shell of a new energy power battery. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] In the processing of aluminum shells for new energy power batteries, stamping is usually used to ensure the integrity of the aluminum shell and maintain its integrity to improve the sealing effect. Traditional stamping dies usually leave an extra part of the material at the edge during processing. This part of the material often needs to be removed in an extra step after stamping, which increases the processing steps. In order to improve this problem, reduce the processing steps and improve processing efficiency, a new type of stamping die for aluminum shells of new energy power batteries is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a stamping die for aluminum shell of new energy power battery, which has the technical effect of improving processing efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stamping die for aluminum shells of new energy power batteries, including a worktable, a lower die base mounted on the top of the worktable, a lower die cavity provided on the top of the lower die base, a cutter provided on the top of the lower die cavity, an upper die base provided inside the cutter, and a stamping cylinder mounted on the top of the upper die base; the lower die base includes an outer frame, a cylinder control switch mounted on the edge of the outer frame, a base located inside the outer frame, a support plate mounted on the top of the base, and a pop-out cylinder mounted on the bottom of the support plate; the cutter includes a main cutter body, a secondary cutter body located outside the main cutter body, a push block mounted on the top of the main cutter body, and a return spring abutting against the top of the push block; the upper die base includes a stamping block and a switch pressure block located on the side of the stamping block.

[0006] As a preferred embodiment of this utility model, the two ends of the outer frame are spaced apart from the outer wall of the base, and the inner side of the outer frame and the two ends of the base form a groove for storing waste materials.

[0007] As a preferred embodiment of this utility model, the cylinder control switch is configured as a push-button switch, the top of the cylinder control switch is higher than the height of the outer frame and the support plate, and the position of the switch pressure block corresponds to the cylinder control switch.

[0008] As a preferred technical solution of this utility model, the tray is symmetrically arranged in two places on the top of the base, the bottom surface of the tray is slidably connected to the contact surface of the base, and the bottom of the tray is fixedly connected to the end of the push rod of the ejection cylinder.

[0009] As a preferred embodiment of this utility model, the outer edge of the lower model cavity is provided with a groove structure corresponding to the main blade body, the main blade body is configured as an annular structure, and the secondary blade body is configured as a long strip shape and is symmetrically fixed on both sides of the main blade body.

[0010] In a preferred embodiment of this invention, both the push block and the return spring are embedded in the slot within the stamping block, and the top of the return spring abuts against the top surface of the slot inside the stamping block.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. This utility model uses a stamping block to stamp and form the material placed on the lower die base. At the same time, the cutter descends with the stamping block and cuts the edge of the material, so that the excess material at the edge is removed while the material is being stamped and formed. When the cutter cuts the material, the push block will squeeze the return spring and thus be subjected to the elastic force of the return spring, thereby gradually increasing the shearing force applied by the cutter to the material, thereby avoiding damage to the cutter blade due to sudden force, thus achieving the technical effect of improving processing efficiency.

[0013] 2. In this invention, the height of the pallet is slightly lower than the edge of the lower mold cavity. When the cutter cuts the edge of the material, the excess material will fall to the top of the pallet. The switch block presses the cylinder control switch while stamping, triggering the cylinder control switch and causing the ejector cylinder to work. The ejector cylinder moves the pallet to the outer ends of the base, thus carrying the excess material that has fallen to the top of the pallet due to cutting to the outside of the mold, thereby achieving the technical effect of convenient waste disposal.

Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example:

[0021] like Figure 1-4 As shown, a stamping die for an aluminum shell of a new energy power battery includes a worktable 1, a lower die base 2 mounted on the top of the worktable 1, a lower die cavity 3 provided on the top of the lower die base 2, a cutter 4 provided on the top of the lower die cavity 3, an upper die base 5 provided inside the cutter 4, and a stamping cylinder 6 mounted on the top of the upper die base 5; the lower die base 2 includes an outer frame 21, a cylinder control switch 22 installed at the edge of the outer frame 21, a base 23 provided inside the outer frame 21, a support plate 24 installed on the top of the base 23, and an ejection cylinder 25 installed at the bottom of the support plate 24; the cutter 4 includes a main cutter body 41, a secondary cutter body 42 provided outside the main cutter body 41, a pusher block 43 installed on the top of the main cutter body 41, and a return spring abutting against the top of the pusher block 43. 44; The upper mold base 5 includes a stamping block 51 and a switch pressure block 52 disposed on the side of the stamping block 51; In use, the upper mold base 5 is moved by the stamping cylinder 6, and the material placed on the lower mold base 2 is stamped and formed by the stamping block 51. At the same time, the cutter 4 descends with the stamping block 51 and cuts the edge of the material, so that the excess material at the edge is removed while the material is being stamped and formed; The switch pressure block 52 presses the cylinder control switch 22 while stamping, so that the cylinder control switch 22 is triggered, which in turn makes the ejection cylinder 25 work. The ejection cylinder 25 drives the support plate 24 to move to the outer ends of the base 23, thereby moving the excess material that has fallen to the top surface of the support plate 24 due to cutting to the outside of the mold for easy handling.

[0022] In other embodiments, the two ends of the outer frame 21 are spaced apart from the outer wall of the base 23, and the inner side of the outer frame 21 and the two ends of the base 23 form a groove for storing waste material, which is used to collect and store the excess material cut by the cutter 4.

[0023] In other embodiments, the cylinder control switch 22 is configured as a push-button switch. The top of the cylinder control switch 22 is higher than the height of the outer frame 21 and the support plate 24, and the position of the switch pressure block 52 corresponds to the cylinder control switch 22. The switch pressure block 52 moves together with the stamping block 51. When the stamping block 51 stamps the material, the switch pressure block 52 presses against the cylinder control switch 22, triggering the cylinder control switch 22. The cylinder control switch 22 is connected to the control circuit of the ejector cylinder 25. When the cylinder control switch 22 is triggered, the push rod of the ejector cylinder 25 will eject.

[0024] In other embodiments, the support plate 24 is symmetrically arranged in two places on the top of the base 23. The bottom surface of the support plate 24 is slidably connected to the contact surface of the base 23, and the bottom of the support plate 24 is fixedly connected to the end of the push rod of the ejection cylinder 25. The height of the support plate 24 is slightly lower than the height of the edge of the lower mold cavity 3. When the cutter 4 cuts the edge of the material, the excess material will fall to the top of the support plate 24 and be carried out as the support plate 24 moves.

[0025] In other embodiments, the outer edge of the lower mold cavity 3 is provided with a groove structure corresponding to the main cutter body 41. The main cutter body 41 is configured as a ring structure, and the secondary cutter body 42 is configured as a strip shape and is symmetrically fixed on both sides of the main cutter body 41. The main cutter body 41 cuts the edge of the material to remove excess material from the edge of the stamped battery aluminum shell, and the secondary cutter body 42 cuts the excess material into two parts.

[0026] In other embodiments, the push block 43 and the return spring 44 are both embedded in the slots in the stamping block 51, and the top of the return spring 44 abuts against the top surface of the slot inside the stamping block 51. When the cutter 4 cuts the material, the push block 43 will squeeze the return spring 44 and thus be subjected to the elastic force of the return spring 44, thereby gradually increasing the shearing force applied by the cutter 4 to the material, thereby preventing the blade of the cutter 4 from being damaged due to sudden force.

[0027] The working principle of this utility model is as follows: During use, the upper mold base 5 is moved by the stamping cylinder 6, and the material placed on the lower mold base 2 is stamped and formed by the stamping block 51. At the same time, the cutter 4 descends with the stamping block 51 and cuts the edge of the material, so that the excess material at the edge is removed while the material is being stamped and formed. The switch block 52 presses the cylinder control switch 22 while stamping, so that the cylinder control switch 22 is triggered, which in turn makes the ejection cylinder 25 work. The ejection cylinder 25 drives the pallet 24 to move to the outer ends of the base 23, thereby moving the excess material that has fallen to the top surface of the pallet 24 due to cutting to the outside of the mold for easy handling.
