Multi-wire saw for cutting high-hardness materials

Abstract

The invention discloses a multi-wire saw for cutting high-hardness materials. The multi-wire saw comprises a workbench capable of oscillating under driving of an oscillating component. A stock plate is placed on the workbench. A multi-wire cutting mechanism is arranged above the workbench and comprises three sheaves in triangular arrangement and wound with cutting wires. The oscillating component comprises a lifter and further comprises a rocker arm; the lifter is provided with provided with a pair of bearing blocks and two ends of a center shaft are mounted in the bearing blocks rotationally; the part, between the two bearing blocks, of the center shaft, is fixedly sleeved with a bearing bush, and the top end of the bearing bush is fixed with the bottom of the workbench; an oscillating rod is fixedly mounted at the bottom of the bearing bush and particularly mounted on an oscillating shaft, two ends of the oscillating shaft are rotationally mounted on a rocker arm support, and the rocker arm support is fixedly mounted on the lifter; one end of the rocker arm is connected to the oscillating shaft while the other end of the rocker arm is mounted on an eccentric shaft, and the eccentric shaft is driven by a motor which is fixedly mounted on the lifter.

Description

technical field [0001] The invention relates to the technical field of wire cutting, in particular to a multi-wire cutting machine. Background technique [0002] Swing multi-wire cutting machine is an effective tool for cutting brittle and hard electronic materials such as artificial gemstones, monocrystalline silicon, rare earth materials, industrial ceramics, crystal, glass, etc. Its cutting line speed can reach up to 500 meters per minute, and the cutting line reciprocating use efficiency High, effectively reducing production costs. [0003] The current swing multi-wire cutting machine mainly includes swing head, cutting sheave, swing motor part, pay-off mechanism, take-up mechanism, wire arrangement device, tension control device, workbench, cutting wire, cooling spraying system; the existing swing The cutting part is installed on the oscillating cutting head by three grooved wheels in an inverted shape. A spindle servo motor drives the three grooved wheels to rotate sy...

AI Technical Summary

Problems solved by technology

Due to the need for the grooved wheel to run the cutting line and perform swing cutting at the same time, the swing of the swing part is small, the cutting speed is low, the precision is low, and even superhard materials (such as sapphire, ruby, ceramics, etc.) cannot be cut. Wait)
