Wire pressing device for linear cutting machine tool

Abstract

The invention discloses a wire pressing device for a linear cutting machine tool. The linear cutting machine tool is provided with the wire pressing device on the other side, opposite to a workpiece, of an electrode wire; the wire pressing device comprises a box body, and a slide mechanism connected to the box body; a first cutting guide wheel and a second cutting wheel are respectively arranged at two ends of the side surface, opposite to the electrode wire, of the box body; the first cutting guide wheel is connected with the slide mechanism through a first fixed block; the second cutting guide wheel is connected with the box body through a second fixed block; wire pressing grooves for accommodating the electrode wire are respectively formed in one surfaces, opposite to the electrode wire, of the first fixed block and the second fixed block; and the two wire pressing grooves are respectively communicated with the first cutting guide wheel and the second cutting guide wheel. The wire pressing device can adjust the length of the electrode wire on a machining section, and horizontally moves to contact the electrode wire with the workpiece for machining, so that the electrode wire on the machining section is stable in strength, the deformation of the workpiece caused by looseness of the electrode wire in the machining process is prevented, and the machining precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wire cutting equipment, in particular to a wire crimping device for a wire cutting machine tool. Background technique [0002] At present, the wire-cut electric discharge machine tools at home and abroad have accounted for more than 60% of the total number of electric-processing machine tools. Wire cut Electrical Discharge Machining (WEDM for short), also known as wire cutting, its basic working principle is to use Thin metal wires (called electrode wires) are used as electrodes to perform pulse spark discharge on the workpiece to remove metal and cut into shape. It is mainly used to process various complex and precise workpieces, such as punches, dies, punches and dies, fixed plates, stripping plates, etc. of punching dies, metal electrodes for forming tools, templates, and EDM. , all kinds of micro-hole grooves, narrow slits, arbitrary curves, etc., have outstanding advantages such as small machining a...
