4. The stamping device can directly bear large force, but the die will fail under eccentric load.

5. If the ambient temperature is lower than 0°C, it should be turned on for a few minutes before working.
The shearing technology of the shearing station is divided into dislocation shearing and punching shearing.

Busbar processing machine
The shearing method adopted by the shearing station, the three-station busbar processing machine, belongs to dislocation shearing. In this way, the design of the mold is simple to manufacture, the price of the busbar processing machine is simple, and the cutting method is concise, which is convenient for users to understand, operate and maintain. However, the busbar incision is often uneven, the smooth area of the incision is small, and the incision is inclined, which cannot meet the requirements of use.
2. Punching and shearing.
After investigation and relevant data analysis, the design adopts punching and shearing method. This processing method is more similar to punching than shearing, except that the shape of the punching hole is a narrow rectangle, which is a closed shearing. During punching and shearing, since both sides of the cutting edge of the tool are in contact with the busbar, the forces on both sides are symmetrical, so the uniformity and quality of the machined busbar incision are better than the former.
Knife design for cutting station.
The shearing tool is the main working part of the busbar forming. The whole set of shearing knives is divided into upper and lower parts, the upper part is the upper cutting knife, the lower part is the fixed knife, one on the left and one on the left, one on the left and one on the left. This design takes into account that the busbar is generally placed on the lower processing table, which is more convenient for positioning and processing; secondly, during processing, the weight of the tool itself can be fully utilized to convert it into useful work and improve the processing quality. It avoids the disadvantage that the upward movement of the fixed knife becomes the resistance.
In the design of the tool shape, there are generally edge tools and oblique edge tools. When punching and shearing with an ordinary cutting edge tool, the entire cutting edge plane is in contact with the sheet material at the same time, so when punching large or thick plate workpieces, the punching force is often large. If the cutting edge plane of the tool is made to be inclined at an angle to the horizontal plane, the cutting edge will not cut in at the same time during punching and shearing, but will punch the material gradually, which is equivalent to reducing the shearing section area, thus reducing the punching force and reducing the punching force. Reduce the impact on the tool, so this design uses a beveled edge tool
