Abstract

A pulse power supply of a medium-speed and high-speed wire cutting machine is mainly composed of a power supply circuit, a high frequency circuit, a decoding circuit and a control circuit. By arranging the control circuit and the decoding circuit, the pulse voltage of the high frequency circuit outputs positive and negative pulse voltage, so that the problems of short circuit, broken wire, distortion of cutting traces and low processing efficiency caused by alumina residual when wire cutting is conducted on aluminum parts are solved.

Description

Technical field [0001] The invention belongs to the technical field of wire cutting processing, and particularly relates to a pulse power supply for a medium wire and fast wire wire cutting machine tool. Background technique [0002] At present, the wire cutting produced by most manufacturers uses a fixed conductive block to feed in. It is normal when cutting ordinary steel, copper, and cemented carbide. However, in the process of cutting aluminum, problems such as short circuit, wire breakage, and cutting track distortion are prone to occur, and the processing efficiency is low. Through observation and analysis of actual processing, it is found that aluminum parts processed by wire cutting have special physical and chemical characteristics. [0003] During the cutting process, the molybdenum wire slowly approached the aluminum piece. When the positive and negative electrodes reached a certain electric field strength, the discharge meson (emulsion) was broken down. Spark discharg...
