Safety lever of punch

Abstract

The invention discloses a safety lever of a punch, which comprises a supporting seat, a steel rope, a lever bracket, hemp ropes and pulleys. By taking the use direction as a reference, the lower end of the steel rope is fixedly positioned on a punching head of a mold, the upper end of the steel rope is fixedly connected with one end of the lever bracket, an articulated structure is arranged on the lever bracket and is articulated and connected with the other end of the supporting seat, one end of the supporting seat is fixedly arranged at the upper end of the punch, both ends of a cross arm at the other end of the lever bracket are fixedly connected with one end of one hemp rope respectively, the two hemp ropes goes around the pulleys respectively, the other end of each hemp rope is provided with a noose, and the pulley is fixedly positioned on the outer side wall of the lower end of the punch. The mechanism effectively avoids the generation of the industrial injury of a worker, can be installed on any punch, can be used without any power and has simple structure, convenient operation and reliable use.

Description

technical field [0001] The invention relates to a safety device for a press, in particular to a safety lever for a press. 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, and currently the most used safety device for punching machines is the photoelectric safety device, which is mostly used in pneumatic punching machines. It is seldom used in mechanical punching machines because this device works by turning on or off the electric signal of the clutch and brake between the punch crankshaft and the transmission wheel through the photoelectric induction device. If the safety of the punching machine occurs in If...

AI Technical Summary

Problems solved by technology

It is seldom used in mechanical punching machines because this device works by turning on or off the electric signal of the clutch and brake between the punch crankshaft and the transmission wheel through the photoelectric induction device. If the safety of the punching machine occurs in The mechanical part of the clutch and brake that controls the movement of the punch crankshaft, then the photoelectric sensing device will not work

The mechanical failure rate of clutches and brakes on mechanical presses is higher than that on pneumatic presses

The electrical control is weaker, and the cost of changing to a photoelectric safety device is relatively high compared to the punch itself, and the safety effect is not good, especially for domestic mechanical punches.
