Abstract

This invention relates to the field of wire threading equipment technology, and discloses a wire fixing device for convenient wire threading operation when installed on a medium-speed wire EDM machine. The device includes: a mounting box, positioned above the head of the medium-speed wire EDM machine for overall fixing and disassembly; a mounting base plate, independently positioned on one side of the bottom of the mounting box; a wire clamp, positioned on one side of the end face of the mounting base plate for clamping and fixing the molybdenum wire; a pneumatic push rod, positioned at the top inside the mounting box; a triangular sliding support mechanism, positioned inside the mounting box and connected to the output end of the pneumatic push rod; and a spring-loaded lever mechanism, positioned on the other side of the end face of the mounting base plate. This invention enables rapid straightening and track return of the molybdenum wire, allowing for quick installation and adjustment of the molybdenum wire by a single operator, and is simple to operate. This wire threading and fixing device is compatible with most medium-speed wire EDM machines on the market, and the entire device can be directly and independently modified and installed on the equipment without affecting the processing accuracy or energy consumption.
