Wire saw twisting machine and method for preventing eccentric grinding of diamond wire saw by using the wire saw twisting machine

Abstract

The invention discloses a wire saw rotary machine. The wire saw rotary machine comprises a rotary rack which rotates coaxially with a diamond wire saw, wherein a wheel set which is formed by at least three rotary trolleys is arranged in the rotary rack; the rotary trolleys are axially arranged next to the diamond wire saw in front, middle and rear positions; the groove on the face of each of the rotary trolleys is rolled on the diamond wire saw; the included angles of the central faces of the trolley bodies between two rotary trolleys are 120 degrees; guide wheels which are located on the same side of the diamond wire saw are arranged on front and rear sides of the rotary rack; the groove of the face of each guide wheel is rolled on the diamond wire saw. A method for preventing eccentric wear of the diamond wire saw by adopting the wire saw rotary machine is implemented by arranging the wire saw rotary machine on a wire saw. The self-rotating ability of the diamond wire saw cutting is increased by virtue of the wire saw rotary machine so as to prevent eccentric wear of the diamond wire saw.

Description

technical field [0001] The invention relates to the cutting processing (cutting granite, steel pieces, etc.) technology of a diamond wire saw, in particular to a wire saw twisting machine and a method for preventing eccentric wear of a diamond wire saw by using the wire saw twisting machine. Background technique [0002] Diamond wire saws have been widely used in stone mining, special-shaped cutting and building component cutting, but under certain working conditions, diamond wire saws often suffer from eccentric wear during the cutting process and are scrapped ahead of time. [0003] Eccentric wear means that during the use of the diamond wire saw, the beads do not wear evenly along the circumferential surface, but only wear one side of the beads, resulting in serious wear on one side of the beads or even grinding to the wire rope, while the other side has a thicker working layer. As a result, the life of the diamond wire saw is greatly shortened and scrapped ahead of sched...

AI Technical Summary

Problems solved by technology

[0006] 1. The customer did not use it according to the specification, did not twist at all or the number of twisting circles was not enough

[0007] 2. The cutting object has high toughness, the chips are not easy to break, and the beads are greatly assisted, which hinders the rotation of the wire rope axis

[0008] 3. The amount of cutting is too large, and the beading exerts too much pressure on the cutting object, resulting in excessive friction between the beading and the cutting object, which hinders the beading from rotating around the axis of the wire rope

[0009] 4. In the middle and later stages of diamond wire saw use, the number of torsion circles was not appropriately increased after the wire rope was fatigued, resulting in the wire saw not being able to rotate when cutting
