Safety device of punch

Abstract

The invention discloses a safety device of a punch. The safety device of the punch comprises a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a first deflector rod and a second deflector rod, wherein one ends of the first connecting rod and the second connecting rod are respectively hinged with a punch hammer of the punch; turnings of the L-shaped third connecting rod and the L-shaped fourth connecting rod are hinged with the body of the punch; the other ends of the first connecting rod and the second connecting rod are respectively and movably hinged with one ends of the third connecting rod and the fourth connecting rod; the other ends of the third connecting rod and the fourth connecting rod are respectively and fixedly connected with one ends of the first deflector rod and the second deflector rod; the other ends of the first deflector rod and the second deflector rod are located at one side of an operating floor of the punch, which is near an operator; and arms of the operator stop at both mutually deviating sides of the other ends of the first deflector rod and the second deflector rod. According to the safety device of the punch disclosed by the invention, through arranging a connecting rod mechanism driven by the punch hammer on the punch, when the punch hammer falls, the first deflector rod and the second deflector rod of the connecting rod mechanism automatically push aside the arms of the operator to enable the arms of the operator to automatically be away from the lower side of the punch hammer, and thus, even if the operator forgets to leave the arms from the lower side of the punch hammer by misoperation, the first deflector rod and the second deflector rod can automatically push aside the arms of the operator so as to avoid work injury occurring, and therefore, the increase of the production rate is facilitated.

Description

technical field [0001] The invention relates to a safety device, in particular to a punching machine safety device. Background technique [0002] With the rapid development of my country's industry, the use of punching machines is becoming more and more common. Due to the fact that in the process of processing, especially the processing of multiple varieties and small batches, most of them are manually operated. During the use of punching machines, various work-related injuries are often caused by improper safety devices. Accidents, most of the punch presses currently use photoelectric sensor switches as safety devices. This device can only be used on punch presses controlled by electrical appliances, and cannot be used on mechanical punch presses. It is extremely dangerous for workers operating on small mechanical punch presses. , Workers need to be vigilant all the time during operation, which brings a great mental burden to the operators, and it is impossible to speed up th...
