Folding type electric spark wire cutting and moving module

Abstract

The invention discloses a folding type electric spark wire cutting and moving module. The two ends of a cutting wire are respectively wound inside left and right side grooves of a W-shaped wire wheel;the middle part of the cutting wire is wound on a scissors-shaped tension adjustment mechanism; a wire wheel drive device is used for driving the cutting wire to implement reciprocating wire movementby driving the W-shaped wire wheel to rotate; the cutting wire at the left side is wound on a cutting wire tensioning mechanism; the tension degree of the cutting wire is adjusted by forward and backward rotation movement of the cutting wire tensioning mechanism; the cutting wire at the right side is wound on a conducting mechanism; current is led in through the conducting mechanism and generatesdischarging with a to-be-processed workpiece; and an adapter plate is installed on a machine tool and is rotationally connected with a fixed lower arm. According to the folding type electric spark wire cutting and moving module disclosed by the invention, the cutting wire is driven to do reciprocating wire movement by a single wire wheel drive device; the cost is low; the operation is simple; byrotatable cooperation of the scissors-shaped tension adjustment mechanism and a rotating plate, the adjustment of length and inclination angle of the cutting wire for cutting object segments can be realized; the application range is wide; moreover, the scissors-shaped tension adjustment mechanism can be folded and stored, so the volume is small; and space is saved.

Description

technical field [0001] The invention belongs to the technical field of wire electric discharge cutting devices, and in particular relates to a foldable wire electric discharge cutting module. Background technique [0002] Wire-cut electric discharge machining is a processing technology that uses electric spark discharge to cut and shape workpieces. It has no macroscopic force in the processing process and ignores the hardness and toughness of materials. It is a research hotspot in the field of electrical discharge machining. The core system of WEDM includes a wire-feeding module. The length and inclination of the cutting object section of the existing wire-cutting wire-cutting module require multiple adjustment mechanisms to adjust separately, and the reciprocating wire-feeding of the cutting wire requires two winding wires. The discs are separately driven and reversed, and the overall structure is complex, bulky, inconvenient to operate, and the production cost and use cost...
