Wire saw cutting machine and wire saw rotating control method

Abstract

The invention provides a wire saw cutting machine and a wire saw rotating control method, and belongs to the technical field of wire saw cutting. The problem that the wire saw rotating speed of an existing wire saw cutting machine with a rotating wire saw is difficult to adjust is solved. The wire saw cutting machine comprises a wire saw and at least two guide rolls, wherein rotating heads capableof self-rotating under the driving of driving motors are arranged on the wire inlet sides and / or the wire outlet sides of the guide rolls, the wire saw penetrates through the rotating heads, and at least two limiting roll wheels and at least one positioning roll wheel are arranged on each rotating head. The wire saw rotating control method comprises the steps that a, initial parameters are determined; b, forward control parameters are calculated; c, whether the abrasion of the wire saw is uniform or not when forward rotating is carried out is verified; d, the number of wiring rows when reverse rotating is carried out is calculated; e, reverse control parameters are calculated; f, whether the abrasion of the wire saw is uniform or not when the reverse rotating is carried out is verified; and g, motor control parameters are obtained. According to the wire saw cutting machine and the wire saw rotating control method, the adjustment of the wire saw rotating speed is realized, and the cutting effect is improved.

Description

technical field [0001] The invention belongs to the technical field of wire saw cutting, and relates to a wire saw cutting machine and a wire saw rotation control method. Background technique [0002] Wire saw cutting machine is used to cut brittle and hard materials, such as crystal, glass, silicon anchor, ceramics, etc., can be cut with wire saw cutting machine. The wire saw cutting machine usually consists of a steel wire for cutting and a feed table for feeding. The steel wire is wound on the tensioning device, and then wound back and forth through the grooved guide wheel to form a row of wire nets. And maintain a tension force of 20N-30N. During the cutting process of the wire saw, the wire saw moves at a certain speed relative to the workpiece to be processed. The feed table drives the workpiece to be processed to perform a feed movement and exerts force on the wire saw to make the wire saw cut the workpiece to be processed. [0003] The structure of the wire saw cut...

Problems solved by technology

[0006] In order to make the diamond wire rotate during the cutting process, increase the number of diamond particles participating in the cutting on the diamond wire, and then enable the diamond wire to exert the maximum cutting force, the problem with the wire mesh structure of the above-mentioned diamond wire cutting machine tool is that the rotation of the diamond wire The direction and speed cannot be controlled, and can only be adjusted by changing the winding method. It is difficult to adjust the speed according to the cutting requirements of different materials; and the wire saw can only rotate in one direction. If the wire saw is twisted too much, the wire saw will not be able to continue Rotate and not achieve the expected cutting effect
