Device and method for electric machining with circular electrode and ultrasonic wave used for cutting

Abstract

The invention relates to a device and method for electric machining with a circular electrode and ultrasonic waves used for cutting. A metal wire electrode used for electrode-wire cutting is replaced by the circular electrode so that the problem of wire penetration in the process of cutting can be solved. According to the wire passing speed in the process of wire-electrode cutting, a rotary speed is provided for the circular electrode so that the ionization electricity discharge phenomenon evenly and continuously caused by the circular electrode and metal can be generated, and therefore cutting machining is conducted on a workpiece. A prior wire-electrode cutting power source is improved and optimized so that the electricity discharge requirement of the circular electrode can be met. The parameters such as the rotary speed and the feeding amount of the circular electrode are controlled through an automatic electric control system so that automatic control can be achieved. The device control parameters are reasonable and the machining accuracy is high. Ultrasonic vibration is exerted on the workpiece so that the slag discharging function can be achieved and therefore fine slag generated by electricity discharge of the electrode and the workpiece is rapidly separated from the machined portions.

Description

technical field [0001] The invention relates to a cutting device and method for long metal workpieces, in particular to an electric processing device and method for cutting with circular electrodes and ultrasonic waves. Background technique [0002] When cutting long metal workpieces, the current conventional wire cutting method needs to be perforated first, and the processing efficiency is low; moreover, it cannot be processed due to the length limitation of the beam of the wire cutting machine tool. For the processing technology of this kind of workpiece, laser cutting, plasma cutting and other methods are used in the industry, but these two processing methods have the problem of "match heads" at both ends of the cutting, and the cutting width cannot be guaranteed to be consistent. [0003] Wire cutting is a type of electrical discharge machining. The principle is to connect the two poles of the pulse power supply to the metal workpiece and the wire electrode respecti...
