An automatic wire threading detection structure for a long-life wire collection system

Abstract

The invention discloses an automatic wire threading detection structure for a long-life wire collection system, which includes a first plate body and a bracket, a detection mechanism is installed on the front surface of the first plate body, and a fixed block, the side of the fixed block away from the detection mechanism is fixedly connected with a metal block, the top of the metal block is connected with a metal sheet through a rotating shaft, and the left side of the first plate is fixedly connected with an electromagnet; through the first The outside of the guide wheel is wrapped with ceramics with better hardness and insulation. The service life can reach more than 5 years, and the influence of metal wheel conduction on the overall performance of the equipment is solved. When the electrode wire passes through the metal sheet, the metal sheet The front end is jacked up, and the electrode wire and the metal sheet are connected to receive a successful wire threading signal, which can effectively solve the problem that the metal wheel will affect the processing accuracy of the equipment and increase power consumption. The hardness of the metal wheel is low, and the wheel and the electrode wire continue to rub , the problem of easy damage and low lifespan.

Description

technical field [0001] The invention relates to the technical field of automatic wire threading detection, in particular to an automatic wire threading detection structure for a long-life wire collection system. Background technique [0002] Wire cutting machine tool belongs to the category of electrical processing. Wire cutting machine was also invented in the former Soviet Union in 1960. Its basic physical principle is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. Wire cutting machine tool is made of When the Lazarinko couple in the former Soviet Union studied the phenomenon and causes of the damage of the switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark could melt and oxidize the local metal and be corroded, thus creating and inventing the electric discharge machining method . [0003] According to the running speed of the electrode wire, ...

AI Technical Summary

Problems solved by technology

[0004] The wire cutting machine tool in the prior art uses an automatic wire threading device when in use, but the guide wheel of the automatic wire threading device in the prior art is made of metal, and when the wire electrode contacts the guide wheel, the electrical signal is turned on, Turning off the front-end hydraulic drive, the metal wheel will affect the processing accuracy of the equipment and increase power consumption. The hardness of the metal wheel is low, and the wheel will continue to rub against the electrode wire, which is easy to damage and has a low life. Therefore, a long-life Wire system automatic wire threading detection structure
