Description

Technical Field

[0001] This invention relates to the field of explosion-proof valve technology, specifically to a stamping equipment and production method for producing integrated explosion-proof valve aluminum shells. Background Technology

[0002] The development of new energy batteries is progressing rapidly, and aluminum shells with explosion-proof functions are being used more and more in new energy batteries. Due to the limitations of aluminum shell forming technology, traditional integrated explosion-proof valve aluminum shells have grooves at the bottom, and the explosion-proof valve is placed outside the aluminum shell and welded on the outside, requiring a relatively thick bottom wall, which makes the manufacturing process more difficult.

[0003] In the existing technology, aluminum shell stamping equipment makes it difficult to demold the stamped parts because the formed parts tend to stick to the mold, which affects the stamping efficiency.

[0004] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0005] The technical problem to be solved by this invention is as follows:

[0006] In the existing technology, aluminum shell stamping equipment makes it difficult to demold the stamped parts because the formed parts tend to stick to the mold, which affects the stamping efficiency.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A novel integrated explosion-proof valve aluminum shell stamping equipment includes a worktable, a fixed base fixedly mounted on one side of the top of the worktable, and a rotating plate rotatably mounted on the other side of the top of the worktable via a rotating shaft. A driving assembly for rotating the rotating plate is mounted at the bottom of the rotating plate. An upper stamping mechanism is mounted on one side of the fixed base, and a lifting assembly for driving the upper stamping mechanism to rise and fall is mounted on the fixed base. Several lower stamping mechanisms adapted to the upper stamping mechanism are mounted on the top of the rotating plate, and the several lower stamping mechanisms are arranged in a circular array. A positioning assembly for positioning the rotating plate is mounted on the worktable.

[0009] Furthermore, the drive assembly includes a drive motor fixedly mounted on the bottom of the workbench, a first gear fixedly mounted on the output end of the drive motor, and a second gear fixedly mounted on the outer side of the rotating shaft, with the first gear meshing with the second gear.

[0010] Furthermore, the lifting assembly includes a lifting motor fixedly mounted on the top of the fixed base, a lifting screw fixed to the output end of the lifting motor, a lifting plate threaded on the outer side of the lifting screw, and the lifting plate slidably connected to the fixed base.

[0011] Furthermore, the upper stamping mechanism includes a stamping cylinder fixedly installed on the top of the lifting plate, a limit seat fixedly installed at the bottom of the lifting plate, a limit plate slidably installed at the bottom of the limit seat, and an upper stamping plate fixedly installed at the bottom of the limit plate.

[0012] Furthermore, the lower stamping mechanism includes a mold box, the top of which has an opening, and a lower stamping seat is slidably disposed on the top of the mold box. The top of the lower stamping seat has a stamping groove adapted to the upper stamping plate, and a top template is slidably disposed in the stamping groove.

[0013] Furthermore, a number of top die rods are fixedly installed at the bottom of the top die template. The bottom end of the top die rods passes through the lower stamping seat and is fixed with a limit block. Top die cylinders are symmetrically arranged at the bottom of the mold box. A connecting shaft is hinged between the output end of the top die cylinder and the side wall of the lower stamping seat.

[0014] Furthermore, the positioning assembly includes several positioning plates fixedly installed at the bottom of the rotating plate. The positioning plates are located directly below the upper stamping mechanism. The several positioning plates are arranged in a circular array below the corresponding lower stamping mechanism. A positioning cylinder is fixedly installed at the bottom of the worktable. A positioning seat is fixed at the output end of the positioning cylinder. A positioning groove that matches the positioning plate is provided on one side of the positioning seat.

[0015] Furthermore, a limit switch is provided in the positioning groove, and the limit switch is electrically connected to the drive motor.

[0016] A novel method for producing an integrated explosion-proof valve aluminum shell includes the following steps:

[0017] Step 1: Place the aluminum shell to be stamped into the stamping groove. The rotating plate rotates under the drive of the drive assembly. When the positioning plate moves into the positioning groove, it is positioned. At this time, the corresponding lower stamping mechanism is located directly below the upper stamping mechanism. The positioning plate presses against the limit switch, and the limit switch controls the drive motor to stop rotating, thus completing the positioning of the lower stamping mechanism. After one stamping is completed, the positioning cylinder controls the positioning seat to move down, the limit switch extends, and the drive motor continues to control the rotating plate to rotate. After the lower stamping mechanism that has completed stamping leaves, the positioning cylinder returns to its original position to wait for the next positioning.

[0018] Step 2: The upper stamping mechanism is moved down to an appropriate height by the lifting assembly, and the stamping cylinder controls the limit plate to move down in the limit seat, thereby moving the upper stamping plate into the stamping groove to stamp the aluminum shell to be stamped.

[0019] Step 3: During demolding, the connecting shaft is moved by the top mold cylinder, thereby controlling the lower stamping seat to move down in the mold box, so that the bottom ends of several top mold rods contact the mold box, and drive the top plate and the lower stamping seat to generate relative displacement, thereby ejecting the formed aluminum shell to obtain the aluminum shell body.

[0020] Step 4: Make a hole at the bottom of the aluminum shell body, place the explosion-proof valve body from inside the aluminum shell body into the hole, and weld it.

[0021] The beneficial effects of this invention are:

[0022] In this invention, the upper and lower stamping mechanisms are designed so that the upper stamping mechanism is moved down to an appropriate height by the lifting assembly. The stamping cylinder controls the limiting plate to move down within the limiting seat, thereby moving the upper stamping plate into the stamping groove to stamp the aluminum shell to be stamped. When demolding is required after forming, the connecting shaft is moved by the top die cylinder, thereby controlling the lower stamping seat to move down within the mold box. This causes the bottom ends of several top die rods to contact the mold box, and causes the top die plate and the lower stamping seat to generate relative displacement, thereby ejecting the formed aluminum shell, thus improving demolding efficiency and solving the problem of difficult demolding of formed parts.

[0023] By setting up a positioning component, the positioning plate moves into the positioning groove for positioning during the rotation of the rotating plate. At this time, the corresponding lower stamping mechanism is located directly below the upper stamping mechanism, and the positioning plate presses against the limit switch. The limit switch controls the drive motor to stop rotating, thus completing the positioning of the lower stamping mechanism. This facilitates the rapid stamping process. After one stamping is completed, the positioning cylinder controls the positioning seat to move down, the limit switch extends, and the drive motor continues to control the rotation of the rotating plate. After the lower stamping mechanism leaves after completing the stamping, the positioning cylinder returns to its original position to wait for the next positioning. The positioning efficiency is high, ensuring the high efficiency and accuracy of the stamping process.

[0024] In this invention, a step is added to the edge of the explosion-proof valve, which is placed inside the aluminum shell and welded to the outside, resulting in a thinner aluminum shell wall. This reduces the weight of the aluminum shell while increasing the internal space of the battery cell, all while maintaining the same external dimensions. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-6 The present invention provides a technical solution:

[0035] A novel integrated explosion-proof valve aluminum shell stamping equipment includes a workbench 1, a fixed base 2 fixedly installed on one side of the top of the workbench 1, and a rotating plate 3 rotatably installed on the other side of the top of the workbench 1 via a rotating shaft. A driving assembly for driving the rotating plate 3 to rotate is installed at the bottom of the rotating plate 3. An upper stamping mechanism 4 is installed on one side of the fixed base 2, and a lifting assembly for driving the upper stamping mechanism 4 to rise and fall is installed on the fixed base 2. Several lower stamping mechanisms 5 adapted to the upper stamping mechanism 4 are installed on the top of the rotating plate 3. The several lower stamping mechanisms 5 are arranged in a circular array. A positioning assembly for positioning the rotating plate 3 is installed on the workbench 1.

[0036] The drive assembly includes a drive motor 101 fixedly mounted on the bottom of the workbench 1. A first gear 102 is fixedly mounted on the output end of the drive motor 101, and a second gear 103 is fixedly mounted on the outside of the rotating shaft. The first gear 102 and the second gear 103 mesh with each other.

[0037] The lifting assembly includes a lifting motor 201 fixedly mounted on the top of the fixed base 2. A lifting screw 202 is fixed to the output end of the lifting motor 201. A lifting plate 203 is threaded on the outer side of the lifting screw 202. The lifting plate 203 is slidably connected to the fixed base 2.

[0038] The upper stamping mechanism 4 includes a stamping cylinder 401 fixedly installed on the top of the lifting plate 203, a limiting seat 402 fixedly installed at the bottom of the lifting plate 203, a limiting plate 403 slidably installed at the bottom of the limiting seat 402, and an upper stamping plate 404 fixedly installed at the bottom of the limiting plate 403.

[0039] The lower stamping mechanism 5 includes a mold box 501, the top of the mold box 501 is provided with an opening, the top of the mold box 501 is slidably provided with a lower stamping seat 502, the top of the lower stamping seat 502 is provided with a stamping groove adapted to the upper stamping plate 404, and the top template 503 is slidably provided in the stamping groove.

[0040] A plurality of top mold rods 504 are fixedly provided at the bottom of the top mold plate 503. The bottom end of the top mold rod 504 passes through the lower stamping seat 502 and is fixed with a limit block. Top mold cylinders 505 are symmetrically provided at the bottom of the mold box 501. The output end of the top mold cylinder 505 is hinged to the side wall of the lower stamping seat 502 with a connecting shaft 506. By setting up the upper stamping mechanism 4 and the lower stamping mechanism 5, the upper stamping mechanism 4 is driven down to an appropriate height by the lifting component. The stamping cylinder 401 controls the limiting plate 403 to move down in the limiting seat 402, thereby driving the upper stamping plate 404 to move into the stamping groove to stamp the aluminum shell to be stamped. When demolding is required after forming, the top die cylinder 505 drives the connecting shaft 506 to move, thereby controlling the lower stamping seat 502 to move down in the mold box 501, so that the bottom ends of several top die rods 504 contact the mold box 501, and drive the top die plate 503 and the lower stamping seat 502 to generate relative displacement, thereby ejecting the formed aluminum shell, thereby improving the demolding efficiency and solving the problem of difficult demolding of the formed parts.

[0041] The positioning assembly includes several positioning plates 301 fixedly installed at the bottom of the rotating plate 3. The positioning plates 301 are located directly below the upper stamping mechanism 4. The positioning plates 301 are arranged in a circular array below the corresponding lower stamping mechanism 5.

A positioning groove 304 adapted to the positioning plate 301 is provided on one side of the positioning seat 303.

[0042] A limit switch 305 is installed in the positioning groove 304, and the limit switch 305 is electrically connected to the drive motor 101. By setting up the positioning component, the positioning plate 301 moves into the positioning groove 304 for positioning during the rotation of the rotating plate 3. At this time, the corresponding lower stamping mechanism 5 is located directly below the upper stamping mechanism 4, and the positioning plate 301 presses against the limit switch 305. The limit switch 305 controls the drive motor 101 to stop rotating, thereby completing the positioning of the lower stamping mechanism 5, which facilitates the rapid stamping process. After one stamping is completed, the positioning cylinder 302 controls the positioning seat 303 to move down, the limit switch 305 extends, and the drive motor 101 continues to control the rotation of the rotating plate 3. After the lower stamping mechanism 5 leaves after completing the stamping, the positioning cylinder 302 returns to its original position to wait for the next positioning. The positioning efficiency is high, ensuring the efficiency and accuracy of the stamping process.

[0043] A novel method for producing an integrated explosion-proof valve aluminum shell includes the following steps:

[0044] Step 1: Place the aluminum shell to be stamped into the stamping groove. The rotating plate 3 rotates under the drive of the drive assembly. When the positioning plate 301 moves into the positioning groove 304, it is positioned. At this time, the corresponding lower stamping mechanism 5 is located directly below the upper stamping mechanism 4. The positioning plate 301 presses against the limit switch 305. The limit switch 305 controls the drive motor 101 to stop rotating, thereby completing the positioning of the lower stamping mechanism 5. After one stamping is completed, the positioning cylinder 302 controls the positioning seat 303 to move down, the limit switch 305 extends, and the drive motor 101 continues to control the rotating plate 3 to rotate. After the lower stamping mechanism 5 leaves after completing the stamping, the positioning cylinder 302 returns to its original position to wait for the next positioning.

[0045] Step 2: The upper stamping mechanism 4 is moved down to an appropriate height by the lifting component. The stamping cylinder 401 controls the limit plate 403 to move down in the limit seat 402, thereby driving the upper stamping plate 404 to move into the stamping groove to stamp the aluminum shell to be stamped.

[0046] Step 3: During demolding, the connecting shaft 506 is moved by the top mold cylinder 505, thereby controlling the lower punch seat 502 to move down in the mold box 501, so that the bottom ends of several top mold rods 504 contact the mold box 501, and drive the top platen 503 and the lower punch seat 502 to generate relative displacement, thereby ejecting the formed aluminum shell to obtain the aluminum shell body.

[0047] Step 4: Make a hole at the bottom of the aluminum shell body, place the explosion-proof valve body from inside the aluminum shell body into the hole, and weld it.
