Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, in particular to a mold protection device. Background Art

[0002] During the use of the stamping die, incorrect collisions between the punch head and the workpiece are inevitable, which will not only affect the stamping effect of the workpiece, but also cause certain damage to the punch head. Therefore, it is very important to protect the stamping die. Material interruption, extrusion, and failure to discharge during the stamping process will still damage the die. The traditional approach is manual monitoring. Sometimes manual monitoring fails to detect or detects it in time but the machine is not shut down in time, which will cause damage to the die, increase the difficulty of work, and increase the cost of repair and lost work time.
