Description

Technical Field

[0001] The utility model relates to the technical field of die cutting dies, in particular to a stable buffer mechanism for a battery pole piece forming die cutting die. Background Art

[0002] Battery pole pieces refer to thin metal plates in secondary batteries and battery packs, which are used to make positive and negative electrodes. When battery pole pieces are produced and processed, they are usually formed through die-cutting molds.

[0003] During the use of existing die-cutting dies, the punching tool and the template are usually closed directly by closing the upper and lower dies to complete the punching, but the material is usually not restricted and stabilized to improve the punching quality. For this reason, we propose a stable buffer mechanism for battery pole piece forming die-cutting dies. Utility Model Content

[0004] In view of the above problems, the utility model provides a stable buffer mechanism for a battery pole piece forming and cutting die, which can solve the problems existing in the above background technology.

[0007] In a further technical solution, a connecting guide mechanism is fixedly connected to the top of one end of the downward-pressing stabilizing mechanism, and a fixed limiting mechanism is provided on one side of the upper template.

[0009] In a further technical solution, the downward pressure stabilizing mechanism includes a movable downward pressure rod located outside the bottom end surface of the fixed connecting rod, one end of the movable downward pressure rod is fixedly connected to a connecting end plate, and one side of the connecting end plate is fixedly connected to a connecting handle.

[0010] In a further technical solution, a fixed connecting column is fixedly connected to the inner top of the connecting sleeve, and fixing grooves are provided inside the connecting chassis and the fixed connecting rod.

[0011] In a further technical solution, the connection guide mechanism includes a connection frame, and a rectangular through groove is formed inside the connection frame.

[0012] In a further technical solution, the fixing and limiting mechanism comprises a threaded barrel, the inner side of which is threadedly connected with a connecting bolt, and the surface of the connecting bolt is movably sleeved with a limiting circular ring.

[0013] The beneficial effects of the utility model are:

[0014] Through the buffer mechanism and the downward pressure stabilizing mechanism, when the upper mold plate and the lower mold plate are closed for punching, the downward pressure stabilizing mechanism first presses down the material to keep the material in a stable state, and at the same time the buffer mechanism can shrink and buffer by itself, so that the downward pressure stabilizing mechanism and the material are in a stable connection state, the overall structure is simple and easy to operate;

[0023] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings. Example

[0024] like Figure 1-Figure 5 As shown, a stable buffer mechanism for a battery pole piece forming die-cutting mold includes a lower template 1, a connecting base plate 2 is provided on the top of the lower template 1, a fixed template 3 is provided on the top of the connecting base plate 2, an upper template 4 is connected to the top of the connecting base plate 2 through a guide column, a buffer mechanism 5 is symmetrically provided on the top of the upper template 4 through bolts, and a downward pressure stabilizing mechanism 6 is provided at the output end of the buffer mechanism 5.

[0025] The working principle of the above technical solution is as follows:

[0026] During use, the buffer mechanism 5 and the downward pressure stabilizing mechanism 6 can cooperate with each other to quickly close the lower mold 1 and the upper mold 4, press the material downward and fix it in a stable state, and then the buffer mechanism 5 can perform stable buffering contraction by itself, so that the whole can be used stably.

[0027] In another embodiment, if Figure 2 As shown, a connecting guide mechanism 7 is fixedly connected to the top of one end of the downward pressing stabilizing mechanism 6 , and a fixed limiting mechanism 8 is provided on one side of the upper template 4 .

[0028] The mutual cooperation between the connecting guide mechanism 7 and the fixed limiting mechanism 8 can limit the position of the downward pressing stabilizing mechanism 6, so that the downward pressing stabilizing mechanism 6 can be used stably. At the same time, the downward pressing stabilizing mechanism 6 can also be quickly disassembled, and then the buffer mechanism 5 can be quickly disassembled and maintained, which is easy to operate.

[0029] In another embodiment, if Figure 3As shown, the buffer mechanism 5 includes a mounting foot 14, one end of which is fixedly connected to a connecting sleeve 15, the inner top of the connecting sleeve 15 is fixedly connected to a force spring 16, the bottom of the force spring 16 is fixedly connected to a connecting chassis 17, the bottom of the connecting chassis 17 is fixedly connected to a fixed connecting rod 18, and a force groove 19 is provided on the outer side of the bottom end surface of the fixed connecting rod 18.

[0030] In order to facilitate the downward pressing of the stabilizing mechanism 6 when it comes into contact with the material, the upper template 4 as a whole will still move downward. At this time, the fixed connecting rod 18 can automatically retract toward the inside of the connecting sleeve 15, pushing the connecting chassis 17, so that the force spring 16 can retract inside the connecting sleeve 15, thereby providing buffering and facilitating operation.

[0031] In another embodiment, if Figure 4 As shown, the downward pressing stabilizing mechanism 6 includes a movable downward pressing rod 20 located outside the bottom end surface of the fixed connecting rod 18, one end of the movable downward pressing rod 20 is fixedly connected to a connecting end plate 21, and one side of the connecting end plate 21 is fixedly connected to a connecting handle 22.

[0032] The movable pressing rod 20 can be quickly put on the outer side of the bottom end surface of the fixed connecting rod 18, and be stuck in the inner side of the force groove 19 for connection and use. Pulling the connecting handle 22 can quickly drive the connecting end plate 21 and the movable pressing rod 20 to move, which is convenient for quick disassembly and assembly operations and easy to use.

[0033] In another embodiment, if Figure 3 and Figure 5 As shown, a fixed connection column 23 is fixedly connected to the inner top of the connecting sleeve 15 , and a fixing groove 24 is opened inside the connecting chassis 17 and the fixed connection rod 18 .

[0034] When the fixed connecting rod 18 is retracted toward the inside of the connecting sleeve 15, the fixed connecting column 23 can be automatically inserted into the inside of the fixing groove 24, so that the fixed connecting rod 18 and the connecting chassis 17 can be in a stable state and avoid being skewed.

[0035] In another embodiment, if Figure 2 As shown, the connecting guide mechanism 7 includes a connecting frame 9 , and a rectangular through slot 10 is formed inside the connecting frame 9 .

[0036] When the distance between the movable lower pressure rod 20 and the connecting end plate 21 and the upper template 4 is reduced, the connecting frame 9 can move up and down outside the surface of the fixed limiting mechanism 8 under the action of the rectangular through groove 10 to perform guiding and limiting, which is easy to operate.

[0037] In another embodiment, if Figure 2As shown, the fixing and limiting mechanism 8 includes a threaded barrel 11 , the inner side of which is connected with a connecting bolt 12 via a thread, and a limiting circular ring 13 is movably sleeved on the surface of the connecting bolt 12 .

[0038] The connecting frame 9 is conveniently sleeved on the outer surface of the threaded tube 11, and the connecting bolt 12 is rotated and inserted into the inner side of the threaded tube 11 to restrict the installation of the limiting ring 13, thereby limiting the position of the connecting frame 9 and preventing the connecting frame 9 from detaching from the outer surface of the threaded tube 11, which is easy to operate.

[0039] The working principle of the utility model is as follows: during use, when the lower mold plate 1 and the upper mold plate 4 are molded together, the movable lower pressure rod 20 and the connecting end plate 21 will first press down and fix the material, and then the upper mold plate 4 will continue to move downward, so that the distance between the upper mold plate 4 and the movable lower pressure rod 20 and the connecting end plate 21 is reduced, and the fixed connecting rod 18 can push the connecting chassis 17, and the fixed connecting rod 18 will shrink toward the inside of the connecting sleeve 15, and the force spring 16 will shrink under the force, so as to buffer, and the connecting frame 9 can be on the outside of the surface of the threaded tube 11. Move, at this time, the punching of the material is completed, when it is necessary to disassemble the buffer mechanism 5 and the downward pressure stabilizing mechanism 6 as a whole, rotate the connecting bolt 12, disassemble the limiting ring 13, and then pull the connecting handle 22 to drive the connecting end plate 21 and the movable downward pressure rod 20 to move, so that the movable downward pressure rod 20 is pulled out from the outside of the bottom end of the fixed connecting rod 18, and the downward pressure stabilizing mechanism 6 is disassembled as a whole, and finally the bolts between the buffer mechanism 5 and the upper template 4 are rotated and disassembled, and then the buffer mechanism 5 can be disassembled for easy maintenance. The overall structure is simple and the operation is convenient and quick.

[0040] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
