a punch

Abstract

The invention provides a punch press. A waste recovery device, a puncher pin detection device and a punching detection device are arranged on a punch press body, a conveying belt can be utilized to perform waste collecting treatment, waste is not piled nearby the punch press, inconvenient working or safety problem is avoided, and recovery is convenient; an infrared transmitter and an infrared receiver are arranged, and when a puncher pin breaks off, the infrared receiver receives a signal and transmits the signal to a control system for alarming, so that an operator stops working and performspuncher pin replacement; a laser detector and a pressure sensor are also arranged, the pressure sensor is located on the conveying belt, when waste falls, the pressure sensor is triggered, the waste can be conveyed to the control system to indicate that the work is normally performed, when the puncher pin falls while the pressure sensor does not produce a signal, it is indicated that the puncher pin works abnormally, and the laser detector detects the shape size of a punched hole according to a reflected laser beam and transmits the shape size to the control system for comparison. The punch press can detect the situation of the puncher pin and detect whether the puncher pin works normally or not in time.

Description

technical field [0001] The invention relates to the field of punching machines, in particular to a punching machine. Background technique [0002] Punch production is mainly for sheet metal. Through molds, it can make blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts, etc., which are widely used in various fields. When punching, because the pressure on the stamping die is relatively large, the punch is easy to break during stamping. At the same time, the waste after punching usually falls directly on or near the punching machine, which takes time to clean up, which is very inconvenient. And the current punching process generally adopts an automatic feeding device. Workers cannot observe whether the punching is successful during the work process. They need to be processed to find out. Not only must the machine be stopped for maintenance, but also the waste of the plate before the problem is found . Finally, in ensurin...

Problems solved by technology

When punching, due to the relatively large pressure on the stamping die, the punch is easy to break during stamping

At the same time, the waste after punching usually falls directly on or near the punching machine, which takes time to clean up, which is very inconvenient

And the current punching process generally adopts an automatic feeding device. Workers cannot observe whether the punching is successful during the work process. They need to be processed to find out. Not only must the machine be stopped for maintenance, but also the waste of the plate before the problem is found

Finally, in order to ensure that the punch does not break and the punching work is carried out, the existing punching machine cannot detect the quality of the punching
