Dustproof and waterproof wire cut electric discharge machine

Abstract

The invention discloses a dustproof and waterproof wire cut electric discharge machine which comprises a machine body, a shore installed on the machine body, and a movement wire mechanism. The shore is further provided with a plurality of transition guide wheels used for guiding wire electrodes, the shore includes an upright post, an upper arm, a lower arm, and the upright post is perpendicularlyarranged on the machine body; the upper arm is perpendicularly arranged on the upper end of the upright post, the lower arm is perpendicularly arranged on the lower end of the upright post, and the free end of the upper arm is provided with a taper device and an upper leading wheel; the free end of the lower arm is provided with a lower leading wheel, the lead-out wire electrodes by the movement wire mechanism through a plurality of transition guide wheels, the taper device, the upper leading wheel, and the lower leading wheel become a closed path between the upper leading wheel and the lowerleading wheel. The dustproof and waterproof wire cut electric discharge machine adopts the movement wire mechanism with a higher movement efficiency, and a more stable and more reliable movement can greatly avoid a wire break situation caused by the movement wire mechanism.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a wire electric discharge machine tool. Background technique [0002] Wire Electrical Discharge Machining (WEDM for short) belongs to the category of electrical machining. Its basic principle is: free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. At this stage, a current is established between the two plates. As a result, countless collisions between particles form a plasma region, which quickly rises to a high temperature of 8,000 to 12,000 degrees, and some materials are instantly melted on the surfaces of the two conductors. At the same time, due to the vaporization of the electrodes and the dielectric fluid, a bubble is formed. And its pressure regularly goes up until very high. Then the current is interrupted, and the temperature suddenly drops, causing the bubble to explode inward, and the resulting power...
