A fast wire threading auxiliary device for wire cutting machine tool

Abstract

The invention discloses a rapid wire passing assistor of a wire-cut electrical discharge machine. The rapid wire passing assisting device comprises an assistor body, one of ends of the assistor body is provided with a wire leading hole for an electrode wire to pass through, a wire clamping seam used for clamping the electrode wire is arranged in the hole wall of the wire leading hole, the middle of the assistor body is provided with a pole portion with a probe hole, and a probe is arranged in the probe hole. The rapid wire passing assistor has the advantages that during wire passing, the head portion of the electrode wire needs to pass through the wire leading hole to slip into the wire clamping seam so as to enable the wire clamping seam to clamp the electrode wire to perform wire passing operation, rapidness in wire passing is achieved, efficiency is improved, damage to the electrode wire never occurs, risks of wire breaking are lowered, security issues are omitted, and safety protection of operators in wire cutting during operation is improved; during wire passing or machine tool cleaning, the probe can be used in detection and scaling when the seam or a slot is found to be difficult to clean.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a fast wire threading assistant for a wire cutting machine tool in the tooling fixture. Background technique [0002] Wirecut Electrical Discharge Machining (Wirecut Electrical Discharge Machining referred to as WEDM), which belongs to the category of electrical processing, was discovered by the former Soviet Union Lazarinko and his wife when they studied the phenomenon and causes of switch contacts damaged by spark discharge corrosion, and found that the instantaneous high temperature of electric sparks can make local The metal is melted, oxidized and corroded, thus creating and inventing the EDM method. [0003] Whether the wire electric discharge machine tool is a fast wire cutting machine or a slow wire cutting machine tool, a basic operation to realize wire electric discharge cutting is wire threading, that is, pulling the electrode wire (such as molybdenum wire, copper wire) wound on th...

Problems solved by technology

[0004] The whole wire threading process only needs the operator to pinch the electrode wire (such as molybdenum wire, copper wire) of 0.1 mm to 0.2 mm (different workpieces are processed by different machine tools, and the wire cutting wire is configured differently) for wire threading, and the efficiency is compared Low

During the wire threading process, the electrode wire often slips out of the guide wheel or the conductive block. The operator usually directly corrects it by hand, which is not safe, and is easy to damage the electrode wire, resulting in premature wire breakage during the wire cutting process.
