Description

technical field [0001] The invention relates to a safety protection device for a punch press, in particular to a safety single punch controller for a punch press. Background technique [0002] The safety single-stroke controller is specially developed for the continuous punching phenomenon that occurs during the stamping operation of ordinary punching machines. The trigger ejector rod of ordinary punching machines cannot be reset due to failure, or the reset is unstable, or it cannot return to the original position, resulting in continuous punching. The main reason for this is that once continuous punching occurs, the mold or punch will be damaged in the light, and the limbs of the staff will be disabled in the severe case, and even life-threatening. Contents of the invention [0003] Therefore, the object of the present invention is to provide a safe single-flush controller for a punch press with high safety, anti-misoperation and simple structure. [0004] The purpose o...
