Molybdenum-wire guiding device of wire cutting machine tool

Abstract

The invention discloses a molybdenum-wire guiding device of a wire cutting machine tool, comprising a guiding wheel frame and guiding wheels, wherein the peripheral surfaces of the guiding wheels are provided with V-shaped guiding grooves; and the guiding wheels comprise an upper guiding wheel and a lower guiding wheel which are respectively riveted on two frame plates of the guiding wheel frame. The molybdenum-wire guiding device also comprises arc-shaped guiding rails made of alloy, wherein the axes of the arc-shaped guiding rail are coincided with that of the lower guiding wheel; the arc-shaped guiding rails are arranged at the front part of the guiding wheel frame and are detachably connected with the frame plates; and the gap between the arc-shaped guiding rails on the two frame plates is opposite to the V-shaped guiding groove of the lower guiding wheel. The molybdenum-wire guiding device disclosed by the invention has the advantages that due to adoption of the structure, the gap between the arc-shaped guiding rails plays a role in guiding the molybdenum wires embedded into the V-shaped guiding grooves of the guiding wheels, the molybdenum wires can be conveniently installed, and the operation is convenient; and the arc-shaped guiding rails are made of high-hardness and wear-resistant alloy, so that the service life is long.

Description

technical field [0001] The invention relates to a wire cutting machine tool, in particular to a molybdenum wire guiding device of the wire cutting machine tool. Background technique [0002] In the current prior art, a guide device for molybdenum wire of a wire cutting machine tool includes a guide wheel frame and a guide wheel, and there is a V-shaped guide groove on the circumferential surface of the guide wheel; the guide wheel is divided into an upper guide wheel and a lower guide wheel , the upper and lower guide wheels are pivotally connected to the two plates of the guide wheel frame with pivots respectively. The thickness of the guide wheel is only 1.9mm, the V-groove on the guide wheel has only 1mm opening, and the bottom is a small arc of R0.1mm, because the center of the front guide wheel seat of most fast and medium wire cutting machine tools is 12mm (less Part of the gap is 15mm), and the small area of ​​the wire hanging makes it more difficult to install the m...

Problems solved by technology

The thickness of the guide wheel is only 1.9mm, the V-groove on the guide wheel has only 1mm opening, and the bottom is a small arc of R0.1mm, because the center of the front guide wheel seat of most fast and medium wire cutting machine tools is 12mm (less Part of the gap is 15mm), and the small wire hanging area and other reasons make the installation of molybdenum wire more difficult, resulting in unnecessary waste of time, reducing work efficiency and increasing processing costs.
