Description

Technical Field

[0002] In the stamping process, after the punch press completes the punching and shearing of metal plates or other materials, there is usually a step to eject the processed parts from the mold. This process is usually called ejection, discharge or sheet discharge. The punch press is usually equipped with a special ejection mechanism, which is designed to discharge the processed parts from the mold, and the material is ejected from the workstation through the driving action of the drive unit to complete the stamping process of the workpiece. However, after the stamping process is completed, if the workpiece is affected by the interference of other components and the workpiece is offset, it will be impossible to ensure that the workpiece is in the appropriate position during ejection, which affects the accuracy of the ejection action and causes the workpiece to shift in position after ejection.
