Abstract

The invention relates to a pneumatic auxiliary threading device of a numerical control electrospark wire-electrode cutting machine tool which is suitable for oil-contaminated and moist working environment with low fault rate, convenient threading and safe operation. The pneumatic auxiliary threading device of a numerical control electrospark wire-electrode cutting machine tool comprises an upper wire feeder and a lower wire feeder. The upper wire feeder and the lower wire feeder are provided with magnetic rodless cylinders, and air inlets are arranged at both ends; each magnetic rodless cylinder is provided with a magnetic rodless cylinder slider; a guide rail is arranged below the magnetic rodless cylinder and is provided with a slider which is fixedly connected with the magnetic rodless cylinder slider; and a mini-type cylinder is fixed at the lower end of the slider through a mini-type cylinder fixed base and is connected with a pneumatic collet chuck. The invention has the advantages that: firstly, the wire feeder is provided with the magnetic rodless cylinder so that the pneumatic auxiliary threading device of the numerical control electrospark wire-electrode cutting machine tool is suitable for oil-contaminated and moist working environment with low fault rate, convenient threading and safe operation, and secondly, molybdenum wires are clamped by the pneumatic collet chuck, thereby reducing the labor intensity of workers, improving the working efficiency and ensuring safer operation.

Description

technical field [0001] The invention relates to a pneumatic auxiliary wire feeding device for a CNC wire cutting machine tool which is suitable for oily and humid working environments and has low failure rate, convenient wire feeding and safe operation, and belongs to the technical field of CNC wire cutting machine tools. Background technique [0002] At present, in the structural design of CNC wire-cut electric discharge machine tools sold on the market, the upper molybdenum wires are all manually loaded without any auxiliary devices. Its disadvantages: First, the molybdenum wire is easy to break when feeding the wire, and it is easy to break away from the V-shaped groove of the guide wheel and the conductive block; second, the operator is easy to cut the fingers when feeding the wire; Large-stroke models cannot be threaded by one person. Contents of the invention [0003] Design purpose: To avoid the deficiencies in the background technology, to design a pneumatic auxil...
