Description

Technical Field

[0001] This utility model belongs to the field of new energy battery production technology, and specifically relates to a production device for aluminum sheets for new energy battery casings. Background Technology

[0002] Aluminum sheets can be processed into battery casings of various shapes and sizes to provide mechanical protection for the battery and prevent the internal cells from being physically damaged by external factors such as collisions and compression. At the same time, aluminum casings also have good heat dissipation properties, which can help the battery dissipate heat quickly during operation, reduce the battery temperature, and improve the battery's safety and stability. For example, aluminum is used for the casings of some cylindrical and square batteries.

[0003] Aluminum has good plasticity, and aluminum sheets can withstand large deformations without breaking during the stamping process. When manufacturing battery casings with complex shapes, aluminum sheets can be gradually formed into the required shape through multiple stamping processes. However, aluminum sheets with good plasticity are prone to irregular deformation during processing, which can cause them to deviate from the mold and lead to defective products. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a production device for aluminum sheets used in new energy battery casings.

[0005] To achieve the above objectives, this utility model provides a production device for aluminum sheets used in new energy battery casings, comprising a top plate, a support rod, and a bottom plate connected from top to bottom. A stamping cylinder is fixedly installed on the top of the top plate, and a drive rod is fixedly connected to the output end of the stamping cylinder. An upper module is fixedly installed at the bottom of the drive rod, and an upper mold is fixedly installed inside the upper module. A lower module is fixedly installed on the top of the bottom plate, and a lower mold is fixedly installed inside the lower module. Both the lower mold and the lower module have through holes on their outer walls, and a positioning component for fixing aluminum sheets is inserted into and slidably connected inside the through holes.

[0006] In the above technical solution, the positioning component further includes a first insert inserted and slidably connected to the through hole, a fixing block inserted and slidably connected to the bottom of the first insert, and the fixing block fixedly connected to the top of the base plate, a second insert inserted and slidably connected to the inside of the first insert, a contact block fixedly connected to the top of the second insert, an adsorption hole opened on the top of the contact block, and an air pipe inserted and fixedly connected to the end of the second insert, the air pipe communicating with the adsorption hole, and the air pipe passing through the first insert, the fixing block and the base plate and connected to an external fan.

[0007] In the above technical solution, a second reset spring is further provided on the outside of the first insert.

[0008] In the above technical scheme, further, the bottom edge of the contact block is fixedly connected with uniformly distributed insertion rods, the insertion rods are inserted and slidingly connected on the top of the first insertion cylinder, and the outer part of the insertion rod is sleeved with a first return spring.

[0009] In the above technical scheme, further, the outer wall of the first insertion cylinder is fixedly connected with an extension arm, the top of the extension arm is inserted with a support, the top of the support is fixedly connected with a pressure plate, the outer wall of the driving rod is fixedly connected with a pressure plate, and the pressure plate is in abutment with the pressure plate after being pressed down.

[0010] In the above technical scheme, further, the support comprises screw rods inserted and rotationally connected on the upper and lower sides of the extension arm, one end of the screw rod is connected with the pressure plate, the end part of the extension arm is rotationally connected with an adjusting wheel, and the adjusting wheel is screwed on the outer part of the screw rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By setting the positioning assembly, the external fan generates wind energy through the air pipe and the adsorption hole and forms air pressure to adsorb the contacted aluminum sheet, thereby positioning the center of the aluminum sheet, so that the aluminum sheet is not easy to deviate in stamping deformation, and the stamping effect is stabilized.

[0013] When the aluminum sheet is irregular, the pressure in different directions of the contact block will be fed back to the first return spring at the bottom, which can buffer the irregular shape of the aluminum sheet while ensuring the adsorption effect, thereby avoiding that the contact block bears too much pressure.

[0014] The automatic downward pressing of the first insertion cylinder is automatically realized through the contact of the pressure plate and the pressure plate during the downward pressing process of the driving rod, thereby greatly avoiding the bearing of pressure from the aluminum sheet, so that the positioning assembly is only used as an adsorption member, the service life is greatly improved, the contact height of the pressure plate can be freely adjusted according to the depth of the mold through the setting of the screw rod, and the adaptation between the positioning assembly and molds with different depths is realized.
