Problems solved by technology

[0003] The battery steel shell is the protective shell of the battery. It needs steel plates to be stretched by machines. In order to improve the quality of stretching, battery steel shells usually need steel plates to be stretched step by step, and the finished product can be effectively increased by step-by-step stretching. rate; while in the prior art, when the steel plate is stretched step by step, it is usually necessary to change the processing position of the steel plate several times, and perform different degrees of stretching at different positions. The position is prone to inaccurate positioning, resulting in defective products, and the cost of the machinery used is high, which is not suitable for small-scale processing and production. When stretching the steel plate, in order to prevent the inaccurate placement of the steel plate from causing scrap products , the position of the steel plate needs to be positioned; and in order to make the stretching effect better, it is usually necessary to use stretching oil to reduce the friction between the mold and the steel plate
[0004] In view of the fact that in the prior art, when the steel plate is stretched step by step, the processing position is changed many times, which reduces the working stretching efficiency and is prone to inaccurate positioning, resulting in defective products. The cost of the machine is relatively high, and it is not suitable for small-scale production. Processing and production, and the need to position the steel plate during the processing process, and the shortcomings of applying stretching oil, it is urgent to develop a method that can stretch the steel plate step by step at the same station, suitable for small-scale processing and production, and can automatically adjust the steel plate Stretching and forming device for cylindrical battery steel case for positioning and applying stretching oil
