Double-end electric spark wire cutting machine and cutting machining method

Abstract

The invention provides a double-end electric spark wire cutting machine tool and method. The machine tool comprises a base, wherein a left wire cylinder part and a right wire cylinder part are fixedlyinstalled on the left side and the right side of the base correspondingly; a workbench capable of moving along the Y axis is arranged on the base. A workbench auxiliary plate is arranged on the workbench. A cross beam assembly is installed at the upper end of the base. A movable wire frame seat capable of moving along the X axis is arranged on the cross beam assembly; a double-head structure upper arm assembly and a double-head structure lower arm assembly which are arranged up and down are mounted on the movable wire frame seat; and the height of the double-head structure upper arm assemblycan be adjusted on the Z axis, the workbench auxiliary plate and an installed clamp are located between the double-head structure upper arm assembly and the double-head structure lower arm assembly, and an electrode wire of the double-head electric spark wire cutting machine tool can conduct cutting machining on two workpieces on the clamp at the same time. According to the machine tool and the method, two workpieces can be cut and machined at the same time, and the machining efficiency is greatly improved while one-way cutting precision machining is achieved.

Description

technical field [0001] The invention relates to a double-head wire electric discharge cutting device, in particular to a double-head wire electric discharge machine tool and a cutting processing method. Background technique [0002] EDM is to use pulse spark discharge to etch the material to be processed for processing. There is no contact between the processing electrode and the material to be processed due to the presence of liquid dielectric, so softer electrodes (tools) can be used to process hard and brittle conductors such as metals. and semiconductor materials. In EDM, moving wire electrode cutting is the most widely used. There are two types of wire electrode cutting: one-way wire cutting (slow wire) and reciprocating wire (fast). Among them, reciprocating wire cutting is a mechatronics technology independently developed by my country with complete intellectual property rights, which is unique to our country. The advantage is that the equipment cost is low, and the ...

Problems solved by technology

[0004] The invention provides a double-head wire electric discharge machine tool and a cutting processing method, which solves the problem that the reversing stripes caused by reciprocating wire cutting (fast wire) wire cutting affect the processing accuracy, and at the same time solves the problem of unidirectional wire cutting (slow wire cutting). ) wire cutting electrode wire cannot be used repeatedly, which solves the problem of cutting and processing two workpieces at the same time, and integrates the advantages of reciprocating wire-cutting (fast wire-moving) electrode wire that can be used repeatedly and unidirectional wire-cutting (slow wire-moving) with high processing accuracy , created a wire electric discharge machine tool and method for simultaneously cutting and processing two workpieces with a double-headed tool electrode
