Novel wire conveying device for numerically-controlled wire cutting electrical discharge machine

Abstract

The invention discloses a novel wire conveying device for a numerically-controlled wire cutting electrical discharge machine. The device is characterized in that a molybdenum wire is connected and coils two wire rollers, and the two wire rollers are rotated by reciprocating to wind the molybdenum wire; after current is introduced and pulse current is produced by the molybdenum wire, metal steel can be cut; and different complex shapes can be formed by cutting under numerical control of a computer. The device achieves the following beneficial effects: 1, the two wire rollers are connected through one molybdenum wire, and the molybdenum wire coils the wire rollers and the wire rollers are rotated by reciprocating, so that resonance is not produced; 2, one of the two wire rollers pulled by the molybdenum wire is rotated by reciprocating in a driving wheel form, and another one is rotated by reciprocating in a driven wheel form during working; and the molybdenum wire is repeatedly utilized, so that the utilization rate of the molybdenum wire is increased; 3, the driven wheel is rotated with damping, so that the tension of the molybdenum wire is constant, so that the processing stability in working is ensured; 4, a motor is fixed to a rack and is rotated by reciprocating; the bolt line spacing of the molybdenum wire coiling the wire rollers is controlled through a wire arranging wheel, so that the vibration caused by reciprocating moving of the wire rollers can be reduced; and 5, the two wire rollers are on the same plane, so that the difficulty in operation is extremely reduced.

Description

technical field [0001] The invention relates to the technical field of cutting machinery, in particular to a novel wire-feeding device for a numerically controlled wire-cut spark machine. Background technique [0002] At present, the CNC wire cutting spark machine device is a molybdenum wire wound on a wire drum, reciprocating in a closed polygonal state, so the tension of the molybdenum wire is loose and tight, and the molybdenum wire will resonate during high-speed rotation, so It will affect the cutting precision. Contents of the invention [0003] The invention solves the defect that the numerical control wire cutting spark machine device reciprocates in a closed polygonal state, so the tension of the molybdenum wire is loose and sometimes tight, and during high-speed rotation, the molybdenum wire will resonate, which will affect the cutting precision. , to provide a new type of CNC wire cutting EDM wire feeding device. [0004] In order to solve the above-mentioned ...
