Description

Technical Field

[0001] The invention relates to the technical field of wire cutting, in particular to a stepped cutting adjustment device for wire cutting equipment. Background Art

[0002] Wire EDM is currently one of the most advanced cutting technologies in the world. Its principle is that diamond wire forms a cutting network, which is then rubbed against the workpiece by the high-speed movement of the wire. Because workpieces must be cut into uniform thickness sheets at once, current wire EDM equipment typically utilizes multiple strands of wire wound together, evenly spaced, to efficiently produce the desired sheet material.

[0003] However, existing wire EDM equipment for workpiece slicing suffers from the following drawbacks: although the cutting lines used to cut the workpiece are evenly spaced, they are all at the same level, making it impossible to create height differences between the multiple cutting positions. This can lead to multiple slices being dropped and damaged simultaneously after being cut simultaneously, and the operator's response time for cutting is short. Therefore, a stepped cutting adjustment device for wire EDM equipment is proposed to address this issue. Summary of the Invention

[0006] Preferably, the lower wiring trough roller is tilted downward at a horizontal angle of A by the side turning mechanism, and the height difference between the highest effective cutting line and the lowest effective cutting line in the horizontal angle A state is much smaller than the height of the sawdust wood frame.

[0007] Preferably, the side profile between the lower wiring trough roller and the upper wiring trough roller is in a right-angled trapezoidal shape, and the upper wiring trough roller is connected to the shaft end of the motor through a coupling, and a lift connector three is installed on the motor.

[0008] Preferably, the middle portion of the semicircular gear block is connected to the shaft via a bearing, and an elevator connector 1 is installed at the outer end of the shaft.

[0012] The beneficial effects of the present invention are: 1. The side-turning mechanism is used to tilt the two lower routing groove rollers downward, so as to form a stepped cutting structure with equal height differences for the distributed cutting lines. This can adjust the traditional horizontally equidistant cutting lines to a stepped cutting line distribution method with equal height differences, which is conducive to forming multiple cutting grooves with equal height differences from left to right on the workpiece to be cut, so as to achieve the effect of cutting off one by one, avoiding the problem of multiple slices falling and colliding at the same time, and providing an operational response time difference for the subsequent orderly unloading. Second, by using a sawdust wooden frame to restrain and fix the bottom of the workpiece to be cut, and combining the fact that the height difference between the highest effective cutting line and the lowest effective cutting line at the horizontal angle A is much smaller than the height of the sawdust wooden frame, the sawdust wooden frame can be cut with the help of the cutting line, which can ensure that the cutting line cuts thoroughly to the bottom of the workpiece, and at the same time maintains the stability of the remaining workpiece in the cutting state, reducing unnecessary cutting obstacles.
