Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery pole block production of new energy vehicle battery, and particularly relates to a lifting type continuous blanking battery pole block forming method. BACKGROUND

[0002] The battery pole block is a relatively important part of the new energy vehicle battery, but with the development of new energy vehicles, the use amount of new energy batteries increases sharply, so it is necessary to produce the parts of the new energy vehicle battery in a high-speed production mode, and therefore people develop a step-by-step continuous blanking mode to blank and form the battery pole block by using a material belt, which generally adopts the mode of putting the material belt into a progressive die to form the battery pole block by step-by-step blanking. 1. The remaining part of the battery pole block blanked and formed on the material belt becomes waste, so the mode of blanking and forming the battery pole block by cooperation between the material belt and the progressive die causes great material waste, resulting in high production cost of enterprises; 2. The material belt is in a continuous motion state during the forming process, so the lower surface of the material belt is always rubbed against the upper surface of the lower die of the progressive die, so that the lower surface of the formed battery pole block is scratched, so that the surface precision of the lower surface of the battery pole block is very poor and cannot meet the production requirements of high-precision battery pole blocks; 3. The blanking die falls from the blanking channel to the conveying surface of the belt conveyor after the finished product is blanked, but the distance between the conveying surface of the belt conveyor and the lower end of the blanking channel is far, so that the blanking die is prone to turn over when falling, so that more manual material sorting (the front surface of the battery pole block needs to face upward for subsequent production) is required when blanking and collecting, thereby affecting the production efficiency and having a relatively high error rate.
