Background

The wire cut electrical discharge machining is called wire cut for short, and the basic physical principle of the wire cut electrical discharge machining is that free positive ions and electrons are accumulated in a field to quickly form 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 NC control monitoring and control is carried out by the servo mechanism, so that the discharge phenomenon is uniform and consistent, and the machined object is machined to become a product with the required size and shape precision.

The existing linear cutting equipment needs to clamp and fix the die parts in the production and machining processes of the die parts, but the fixing effect of the existing clamping structure is poor, so that the die deviation in the cutting process is easily caused, the cutting effect is influenced, the die parts with different sizes cannot be clamped simultaneously, and the use limitation is large.
