Wire threading device for numerical control feeding wire cutting machine

Abstract

The invention provides a wire threading device for a numerical control feeding wire cutting machine, and belongs to the technical field of numerical control. The wire threading device comprises a supporting seat, a wire guiding nozzle, a pin shaft and a finger air cylinder, a hinge plate is mounted in the supporting seat, the hinge plate comprises a first hinge plate body and a second hinge platebody, the first hinge plate body is connected with the supporting seat in a welded mode, the second hinge plate body is movably connected with the supporting seat through the pin shaft, semi-circularcounterbore holes are formed in the end faces of the first hinge plate body and the second hinge plate body correspondingly, the wire guiding nozzle is nested in the semi-circular counterbore holes, bearing seat holes are formed in the first hinge plate body and the second hinge plate body correspondingly, guiding wheels are mounted on the bearing seat holes correspondingly, a rotating bolt is arranged on the side face of the wire threading device, and the finger air cylinder is arranged on the back face of the wire threading device. According to the wire threading device for the numerical control feeding wire cutting machine, the wire threading device is simple in structure, operation is controlled through the finger air cylinder or the bolt, simpleness and convenience are achieved, protecting covers are mounted on the driving guiding wheel and the driven guiding wheel, the phenomenon of sliding of a molybdenum wire is not prone to occurring, the problem that the molybdenum wire is fine and soft and is not easily threaded is solved overall, the wire threading time is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to a wire threader of a numerical control wire cutting machine. Background technique [0002] Wire cutting machine tool belongs to the category of electrical processing. Wire cutting machine was also invented in the former Soviet Union in 1960. Its basic physical principle is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. Wire cutting machine tool is made of When the Lazarinko couple in the former Soviet Union studied the phenomenon and causes of the damage of the switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark could melt and oxidize the local metal and be corroded, thus creating and inventing the electric discharge machining method , at this stage, a current is formed between the two plates, resulting in countless collisions between the par...
