Description

Technical Field

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. When performing plastic deformation processing, stretching stamping is generally used, and a punch stretching device is usually used to stretch the plate.

[0003] The punching machine stretching device is a stamping press. In national production, the stamping process saves materials and energy and has high efficiency compared to traditional mechanical processing. Its principle is to convert circular motion into linear motion. The main motor drives the flywheel, which drives the gear, crankshaft, connecting rod, etc. through the clutch to achieve the linear motion of the slider. The movement from the main motor to the connecting rod is circular motion.

Also, because the emergency stop structure of the device is imperfect, it cannot be stopped in time after an error occurs during operation, which leads to waste of the plate. Therefore, a punching and stretching device is proposed to address the above problems. Utility Model Content
