Wire cutting electric-discharge machining device of double three-dimension position coordinate system

Abstract

The invention provides a dual three-dimensional coordinate line cutting discharge processing device, which consists of two sets of wire movement systems which are not used at the same time; the two upper wire guiding components in the two sets of wire guiding mechanisms are both arranged on an upper wire guiding component installation plate; the two lower wire guiding components are arranged on a lower wire guiding component installation plate. Therefore, the invention establishes the two three-dimensional position coordinate system which consists of two sets of X, Y, U, V, Z five coordinate axises and is formed by the electrode wire section between the upper wire guiding component and the lower wire guiding component corresponding to the workpiece in space position relation; the origin of each coordinate system is the center of the wire guiding hole of respective lower wire guiding elements. A fixed distance L in an X-Y plane is arranged between the origins of the two coordinate systems. When the rough cutting process of the first wire movement mechanism is achieved by a rough wire electrode, an X-Y axis motion trailing bar moves the fixed distance L correspondingly in the X-Y horizontal plane, thus leading the three-dimensional position coordinate system of the second wire movement mechanism to be coincident to the three-dimension position coordinate system of the first wire movement mechanism; a precise cutting discharge process is achieved to the profile of the workpiece for a plurality of times by fine electrode wire of the second wire movement mechanism, thus achieving the cutting process for a plurality of times to the same workpiece sequentially by the two wire movement mechanisms.

Description

technical field [0001] The invention relates to a wire-cut electric discharge machining device, in particular to a wire-cut electric discharge machining device with a double three-dimensional position coordinate system that uses one kind of electrode wire for rough cutting and then uses another kind of electrode wire for fine cutting. Background technique [0002] Wire-cut electric discharge machining is the main processing method for metal molds and conductive special materials. It uses the electric erosion effect produced by electric spark discharge to carry out cutting processing. Such devices are usually composed of four major parts: mechanical movement mechanism, pulse power supply, numerical control system and working fluid supply system. The mechanical movement mechanism is mainly composed of bed, wire transporting parts, U-V-Z axis movement carriage and X-Y axis movement carriage. In order to realize the cutting process of three-dimensional contour shape, the device...
