Description

A wire cutting machine tool fixture

technical field

The invention relates to a clamp for a wire cutting machine tool, which is a clamp for a wire cutting machine tool with simple structure, convenient manufacture and easy operation.

Background technique

Wire cutting machine tool (WEDM), which belongs to the category of electric processing, was discovered by the former Soviet Union Lazarinko and his wife when they studied the phenomenon and causes of spark discharge corrosion damage to switch contacts. They found that the instantaneous high temperature of electric sparks can melt and oxidize local metals. And it was corroded, thus creating and inventing the electric discharge machining method. The wire cutting machine was also invented in the former Soviet Union in 1960. Our country is the first country used for industrial production. It uses moving wires as tool electrodes, and passes pulse currents between the wires and workpieces, and uses the corrosion of pulse discharges. The function is to cut and process the workpiece. Wire EDM can be divided into high-speed reciprocating wire EDM (commonly known as "wire cutting machine"), low-speed unidirectional wire EDM (commonly known as "slow wire") and vertical wire EDM according to the wire speed. There are three types of self-rotating wire-cut electric discharge machines. It can also be divided into single column cross table type and double column type (commonly known as gantry type) according to the form of workbench. The number of wire-cutting machine tools is growing at a rapid rate. According to statistics, the annual output has risen from 2-3 thousand units to tens of thousands. It has become one of the most widely used types of CNC machine tools in my country for various medium and low-grade mold manufacturing and special parts processing.

At present, the fixtures given in the attachments of machine tool manufacturers are similar to the pressure plates used on milling machines and machining centers. When clamping, due to the different sizes and thicknesses of the workpieces and the differences in the wire cutting positions, the adjustment is extremely inconvenient and affects the Processing efficiency, resulting in an increase in production costs.
