AI Technical Summary
After the stamping process is completed, the edge of the steel plate is easily stuck on the punch, which obstructs the movement of the steel plate and affects the discharge of scrap and the feeding of new steel plates.
The design employs a combination of a demolding unit and an auxiliary unit. The demolding unit uses guide rods and demolding springs to achieve rapid separation of the sheet metal from the punch, while the auxiliary unit uses ball bearings and ejection springs to lift the sides of the sheet metal, helping to separate the sheet metal from the lower template.
This enabled rapid demolding of steel plates, smooth discharge of waste plates, and smooth feeding of new steel plates, thereby improving production efficiency.
