Protection method and protection device thereof when using punch

Abstract

The invention discloses a protection method and a protection device thereof when using a punch, which relate to the technical field of punching by using punches. The device mainly comprises a detection part, a hydraulic braking part and a control part, wherein the detection part comprises a light source and a photoelectric sensor; the braking part comprises a hydraulic cylinder, an electromagnetic valve and an oil passage; and the control part comprises a programmable controller and a relay. In case of abnormal situations, the photoelectric sensor sends a signal to the programmable controller (PLC), the PLC processes the signal and simultaneously sends execution commands to the intermediate relay and the electromagnetic valve, and the intermediate relay and the electromagnetic valve immediately cut off a power supply of a motor and cut off the oil passage of hydraulic cylinder after receiving the commands, thereby preventing the inertial motion of a punching head. The device can effectively lead the whole punch to stop working in time, thereby solving the safety problem of an operator. The whole reaction process is rapid and the reliability is high, thereby being particularly applicable to safety devices of ordinary punches.

AI Technical Summary

Benefits of technology

This technology helps keep workers from getting hurt by accidentally hitting their tools with heavy objects or other things that could cause them to move too much during use. It can be used on both regular machine presses and special purpose machinery like drilling equipment.

Problems solved by technology

Technically speaking, current methods for prevention against accidental explosions involve either stopping an engine beforehand or providing extra security measures around them. These techniques have limitations because they require continuous monitoring while still being effective over short periods of times caused by emergency situations like fires or electrical failures. Additionally, these existing systems may take too much room if needed, requiring operators to manually switch between different modes depending upon their needs.
