Description

Lifting door of electric spark wire-electrode cutting machine tool

Technical field

The invention relates to the technical field of wire cut electric discharge machines, in particular to a lifting door of a wire cut electric discharge machine.

Background

A wire-cut electric discharge machine belongs to the field of electric machining, and is characterized by that when the foreign scientist studies the phenomenon and reason of corrosion and damage of switch contact due to spark discharge, the instantaneous high temp. of electric discharge can make local metal be molten and oxidized and corroded, so that it develops and invents an electric discharge machining method. Free positive ions and electrons accumulate in the field, quickly forming an ionized conductive channel. At this stage, a current is established between the plates. Resulting in numerous collisions between the particles, forming a plasma and rapidly rising to a high temperature of 8000 to 12000 c, momentarily melting some of the material on the surfaces of the two conductors, while a bubble is formed due to the evaporation of the electrodes and the dielectric liquid and its pressure rises regularly up to very high levels. The current is then interrupted and the temperature suddenly drops, causing the bubbles to implode, creating a motive force that throws the dissolved material out of the crater, and the corroded material recondenses into small spheres in the dielectric fluid and is drained away by the dielectric fluid. Then, the discharge phenomenon is uniform and consistent through monitoring and control of NC control and execution of a servo mechanism.

Spark-erosion wire cutting machine bed need use the overhead door to protect when using, and traditional overhead door adopts gas vaulting pole structure usually, and original gas vaulting pole structure is nevertheless supplementary overhead door and carries and draw, nevertheless because operational environment has certain corrosivity, can corrode the sealing washer in the gas vaulting pole, lead to leaking gas, and the result of use is not good to can use the overhead door many times every day, also make gas vaulting pole life-span weak, for this reason, provide a spark-erosion wire cutting machine bed overhead door.
