Description

Technical Field

[0001] The present disclosure relates to the field of stamping dies, and in particular to a pole stamping device and stamping equipment. Background Art

[0002] The battery pole is a component used to electrically connect to the battery cell inside the battery to achieve electrical connection. In the prior art, the battery pole is made of metal, such as aluminum pole, copper pole or copper-aluminum composite pole, and is generally formed into a pole of corresponding shape by stamping a metal block with a stamping die.

[0003] For example, a Chinese patent with application number CN202322677195.0 discloses a battery pole stamping die, including an upper die and a lower die. The upper die consists of an upper die seat, an upper pad, an upper clamping plate and an upper template from top to bottom. An upper die forming block is elastically installed in the upper template, and the upper die forming block passes through the upper template. The lower die consists of a lower die seat, a lower pad and a lower template from bottom to top. An inner top block is elastically installed in the lower template. The lower template is provided with a sliding hole running through its upper and lower ends. The inner top block slides up and down in the sliding hole. The height difference between the inner top block and the sliding hole is 0.8-1mm. The diameter of the inner top block is the same as the diameter of the sliding hole, and the diameter of the inner top block is the same as the diameter of the bottom of the battery pole.

[0004] However, the structural design of the above battery pole stamping die has the following problems during use:

[0005] The stamping die is formed by placing a metal block in a lower die seat and then stamping the metal block when the upper die seat and the lower die seat are closed. However, the stamping die is formed by stamping the metal block once, i.e., not by multiple stampings, and there is a problem of low stamping accuracy; on the other hand, for the poles that need to be slotted at the ends, the upper die seat of the die is not provided with a punch, and the slot cannot be stamped out.
