Problems solved by technology

However, for traditional punching machines, the slider drives the upper mold to reciprocate up and down for processing. During the processing, the slider must reciprocate into the processing area, resulting in the blocking of infrared rays. This action will cause serious interference to the photoelectric protection device and make normal processing impossible. conduct

Abstract

The invention discloses an auto-counting and safeguard component of a punching machine. The auto-counting and safeguard component comprises an automatic counting device, a photoelectric protector and a control cabinet. The automatic counting device comprises a photoelectric proximity switch and a flexible support connected with each other. The photoelectric protector comprises a circular shell and a plurality of photoelectric protective units provided within the circular shell. Each photoelectric protective unit comprises an infrared transmitting end, an infrared receiving end and a control circuit; the infrared transmitting end and the infrared receiving end are co-directional and both connected with the control circuit; the control cabinet comprises an independent power supply, a counter and a plurality of relays connected in parallel; the independent power supply is connected with both the counter and the relays; the counter is electrically connected with the photoelectric proximity switch; the relays and the control circuits are connected in one-to-one correspondence. The automatic counting device is made to adapt to the processing modes of traditional punches, and a safeguard device is made to adapt to the processing modes of the traditional punches to allow safeguarding.

Description

technical field [0001] The invention relates to the technical field of automatic control of machine tools, in particular to an automatic counting and safety protection component for a punching machine. Background technique [0002] In the process of punching press processing, there are often injuries caused by the operator's fatigue production or misoperation when adjusting the workpiece to be processed, causing fingers or other parts to be squeezed in the processing area under the slider. With the increasing awareness of safety production, people use the characteristics of infrared transmission to add photoelectric protection devices on the processing operation table of the equipment to prevent human body parts from entering the processing area by mistake during processing and causing injury. The existing photoelectric protection device includes a horizontally arranged transmitter and receiver, which are arranged on both sides of the processing area: if the infrared rays em...
