Abstract

The invention discloses a portable wire cutting saw and relates to the technical field of wire cutting. The wire cutting saw comprises a saw body, universal spray pipes, a wire electrode, a front wire winding mechanism, a front wire guiding mechanism, a rear wire guiding mechanism and a rear wire winding mechanism, wherein the saw body is fixedly connected with a handle, the front wire guiding mechanism is arranged at the end of the saw body, which is far from the handle, and the rear wire guiding mechanism is arranged at the end of the saw body, which is close to the handle; the front wire winding mechanism is located above the front wire guiding mechanism, and the rear wire winding mechanism is located above the rear wire guiding mechanism; one end of the wire electrode is wound on the front wire winding mechanism, the wire electrode sequentially passes through the front wire guiding mechanism and the rear wire guiding mechanism, and the other end of the wire electrode is wound on the rear wire winding mechanism. The using steps of the wire cutting saw comprise preparing the wire electrode, mounting the wire electrode, adjusting the tensioning force, spraying a working solution, starting wire cutting, dismounting for standby use after the cutting is finished. The wire cutting saw can realize narrow-slit cutting, cutting of workpieces with large thicknesses, good cutting surface texture and any curvilinear cutting.

Description

technical field [0001] The invention belongs to the technical field of wire cutting, and more specifically relates to a portable wire cutting saw. Background technique [0002] EDM technology is a processing method that uses spark discharge to remove materials without macroscopic cutting force. It can process various conductive materials with high hardness, high toughness, high viscosity and high brittleness. Wire cutting technology is a kind of electric discharge machining technology, which uses conductive metal wire as electrode, and uses the spark discharge between the wire and the workpiece to etch the workpiece material. Wire cutting technology is widely used. It can cut metal plates with a thickness of more than 1m with extremely thin electrode wires, and can also cut semiconductors or metal plates with a thickness of no more than 100 μm, and the slit is extremely narrow, which can reach less than 100 μm. [0003] In the prior art, wire cutting of workpieces is mostly...
