[0002] Wire cutting is the accumulation of free positive ions and electrons in the field, which quickly forms an ionized conductive channel. At this stage, a current is formed between the two plates. This causes countless collisions between particles, forming a plasma zone, which quickly rises to a high temperature of 8,000 to 12,000 degrees, instantly melting some materials on the surfaces of the two conductors. At the same time, due to the vaporization of the electrode and the dielectric fluid, a bubble is formed, and its pressure rises regularly until it is very high.

[0003] However, in practical applications, most of the existing workpieces are usually dropped directly after wire cutting. However, the cut surface after wire cutting will still retain high temperature. Therefore, the cut surface of the cut piece is affected by the high temperature. During the falling and impacting process, the cut surface is prone to deformation to varying degrees, which will increase the defective rate of the cut piece and is not conducive to its promotion and use.

[0004] Therefore, those skilled in the art provide a wire cutting blanking mechanism to solve the problems raised in the above background technology. Utility Model Content

During the movement of the wire cutting head body 7, the placed workpiece can be cut, and the cut workpiece falls downward into the discharge box 8 under the influence of gravity. At this time, the coolant in the discharge box 8 can buffer the falling workpiece and cool the cut surface of the workpiece at the same time, thereby effectively avoiding the deformation of the cut surface of the workpiece due to high temperature and collision, effectively reducing the defective rate of the workpiece, and is conducive to promotion and use.

The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of a wire cutting unloading mechanism in the embodiment of the present application is as follows: when in use, the workpiece is placed on the processing table 1 as a whole, and the bidirectional screw rod 3 is twisted. The bidirectional screw rod 3 drives the two transmission blocks 2 to approach each other, and the two transmission blocks 2 drive the two clamping rods 4 to approach each other.

As the number of workpieces accumulated inside the unloading box 8 continues to increase, the liquid level of the coolant is also constantly increasing. At this time, the transparent liquid pipe 16 can use the principle of communicating vessels to judge the highest liquid level inside the unloading box 8 to avoid overflow.
