Security punching machine capable of realizing jogging control of punching head

Abstract

The invention relates to a security punching machine capable of realizing jogging control of a punching head, which consists of a worktable, a stander, the punching head, a crank shaft and a driving motor, wherein the punching head is longitudinally and movably arranged on the stander on the upper part of the worktable and is sleeved at the front end of the crank shaft, and the back end of the crank shaft and the driving motor which is fixedly arranged on the back surface of the stander are arranged in linkage. The security punching machine has the following innovative points that: the other end of the crank shaft is provided with an output end big gear wheel of a reducing gear set in a driven mode; a driving shaft of an input end small gear wheel of the reducing gear set is fixedly provided with a driven disk of a pneumatic clutch; and a driving disk of the pneumatic clutch is in linkage with an output shaft of the driving motor. The security punching machine has a scientific and reasonable structural design, realizes the jogging control of the punching head by controlling the engagement and the disengagement of the pneumatic clutch, facilitates die alignment, and has the advantages of stable running, precise control, convenient operation, safe use and the like.

Description

technical field [0001] The invention belongs to the field of stamping machinery, in particular to a safety punch capable of realizing punch inching control. Background technique [0002] Punch is a very common mechanical processing device. At present, the punches of most mechanical punches are driven by rotating the crankshaft to realize the rise and fall of the punch from the highest point to the lowest point of its stroke. However, the existing crankshaft rotates continuously during the rotation process, that is, the punch cannot stop during the operation between the highest point and the lowest point of the stroke, and when placing the lower mold, it is only aligned by the experience of the operator. , with poor alignment accuracy. Since the punch cannot stop during the action, once the punch starts to move, the position of the mold can no longer be adjusted, and the punch must be stopped by means of stopping. Like this, not only causes the inconvenience of operation, r...
