Description

Technical Field

[0001] The utility model relates to the technical field of die cutting dies, in particular to an upper and lower template stroke adjustment mechanism for a battery pole piece forming die cutting die. Background Art

[0002] Battery pole pieces refer to the thin metal plates in secondary batteries and battery packs, which are used to make positive and negative electrodes. When producing and processing battery pole pieces, they are usually formed by die-cutting dies. The battery pole pieces can be punched and formed by the cooperation between the punching tool and the fixed die plate.

[0003] When the existing die-cutting mold is in use, the upper mold plate usually drives the punching tool to extrude between the lower mold plate and the fixed mold plate to complete the punching operation. However, in actual use, the stroke between the upper mold plate and the lower mold plate is usually fixed. If the thickness of the material is different, when the stroke between the upper and lower mold plates is short, the punching tool cannot be pulled out from the inside of the material. When the stroke is too long, there is a large gap between the upper and lower mold plates, which is prone to safety accidents. For this reason, we propose a stroke adjustment mechanism for the upper and lower mold plates of a battery electrode forming die-cutting mold. Utility Model Content

[0026] In another embodiment, if Figure 1 As shown, a fixed buffer mechanism 10 is fixedly connected to the top of the upper template 4 , and an upper hook plate 11 is fixedly connected to the output end of the fixed buffer mechanism 10 .

[0027] When the stroke of the upper template 4 is restricted, the moving stroke of the external servo component remains unchanged and can be buffered by the fixed buffer mechanism 10, thereby ensuring that the external servo component can be normally extended and retracted, and the operation is convenient.

[0028] In another embodiment, if Figure 3 As shown, the connection limiting mechanism 6 includes a movable mounting plate 12, and a second connecting sleeve block 13 is symmetrically provided on the side of the movable mounting plate 12 away from the fixed guide rail 5, and a movable plug rod 14 is movably connected inside the second connecting sleeve block 13, and a force-bearing ring 15 is fixedly sleeved on the outer surface of the movable plug rod 14, and a first force-bearing spring 16 is fixedly connected to one side of the force-bearing ring 15, and a connecting pull block 17 is fixedly connected to the end of the movable plug rod 14 away from the fixed guide rail 5, a connecting handle 18 is fixedly connected to the middle part of the side of the movable mounting plate 12 close to the second connecting sleeve block 13, and a third connecting sleeve block 19 is symmetrically provided on the side of the movable mounting plate 12 away from the second connecting sleeve block 13.

[0029] It is convenient to pull the connecting pull block 17 to drive the movable plug rod 14 and the force-bearing ring 15 to move, so that the force-bearing ring 15 compresses the first force-bearing spring 16, so that one end of the movable plug rod 14 is pulled out from the inner side of the limiting slot 9, so that the movable mounting plate 12 and the third connecting sleeve block 19 can be moved on the outer side of the surface of the fixed guide limiting column 8, so as to perform adjustment, which is easy to operate.

[0030] In another embodiment, if Figure 1 and Figure 3 As shown, a connecting guide block 20 is symmetrically provided on one side of the movable mounting plate 12 away from the second connecting sleeve block 13 , and fixed guide grooves 21 adapted to the connecting guide block 20 are provided on both sides of the fixed guide rail 5 .

[0031] When the installation plate 12 is moved, the end of the connecting guide block 20 can move inside the fixed guide groove 21, which is easy to operate.

[0032] In another embodiment, if Figure 3 As shown, one end of the movable insert rod 14 is in contact with the inner side of the limiting slot 9 , and the inner side of the third connecting sleeve block 19 is in contact with the outer side of the surface of the fixed guide limiting column 8 .

[0033] It is convenient for the end of the movable plug rod 14 to be inserted into the inner side of the limiting slot 9, and at the same time, the third connecting sleeve block 19 can stably move outside the surface of the fixed guide limiting column 8, which is easy to operate.

[0034] In another embodiment, if Figure 4 As shown, the fixed buffer mechanism 10 includes a connecting sleeve 22, the interior of the connecting sleeve 22 is movably connected to a movable connecting rod 23, the bottom end of the movable connecting rod 23 is fixedly connected to a force-bearing chassis 24, and the top of the force-bearing chassis 24 is fixedly connected to a second force-bearing spring 25.

[0035] When the external servo component moves, it can pull the upper hook plate 11, drive the movable connecting rod 23 and the force-bearing chassis 24 to move, and compress the second force-bearing spring 25, thereby performing buffering.

[0036] In another embodiment, if Figure 2 As shown, the interior of the first connecting sleeve block 7 and the outer surface of the fixed guide limiting column 8 are slidably fitted with each other.

[0037] This facilitates the first connecting sleeve block 7 to stably move outside the surface of the fixed guide limiting column 8, and the operation is convenient.

[0038] The working principle of the utility model is as follows: during use, the connecting block 17 is first pulled to drive the movable plug rod 14 and the force-bearing ring 15 to move, so that the force-bearing ring 15 compresses the first force-bearing spring 16, so that one end of the movable plug rod 14 is pulled out from the inner side of the limiting slot 9, so that the movable mounting plate 12 and the third connecting block 19 can be moved on the outer side of the surface of the fixed guide limiting column 8, and then when it is moved to the required adjustment position, the connecting block 17 is released, and the force-bearing ring 15, under the action of the first force-bearing spring 16, can drive the movable plug rod 14 to reset, so that one end of the movable plug rod 14 It can be inserted into the inner side of the limit slot 9 and connected and fixed with the fixed guide limit column 8, so that the moving stroke of the first connecting sleeve 7 on the outer side of the surface of the fixed guide limit column 8 can be adjusted and limited, so that the moving stroke of the upper template 4 can be adjusted and limited. When in use, when the upper template 4 is restricted, the servo component connected to the outside performs normal telescopic operation, which will pull the upper hook plate 11, drive the movable connecting rod 23 and the force-bearing chassis 24 to move, and compress the second force-bearing spring 25, thereby performing buffering, so that the whole can be used normally and stably, and the operation is convenient and quick.
