Discharging four-roller mechanism for diamond wire multi-wire cutting machine

Abstract

The invention relates to a discharging four-roller mechanism for a diamond wire multi-wire cutting machine, and belongs to the technical field of diamond wire cutting, the discharging four-roller mechanism comprises a driving roller assembly, a conductive roller assembly and a conductive element, the driving roller assembly and the conductive roller assembly are arranged at intervals in the vertical direction, and the conductive element is in rolling contact with the conductive roller assembly to supply power to the conductive roller assembly; the driving roller assembly and the conductive roller assembly are of a four-roller structure, by the adoption of the four-roller structure, the included angle of a wire net can be increased, the resultant force of the diamond wire net borne by the driving roller assembly and the conductive roller assembly is reduced, the service life is prolonged, meanwhile, the number of the wire nets is further increased, the distance between the wire nets is reduced, the number of single blades is increased, and the cutting efficiency is improved; the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of diamond wire cutting, and in particular relates to a discharge four-roller mechanism for a diamond wire multi-wire cutting machine. Background technique [0002] In order to improve power generation efficiency, reduce power generation costs, and improve economic benefits, photovoltaic silicon wafers continue to develop in the direction of high efficiency, large sheets, and thin sheets. The diamond wire discharge composite cutting method can improve processing efficiency and reduce cutting load. The application number is CN201910969518.9, and the name is diamond multi-wire electric spark discharge cutting method and wire cutting device. The wire wheel, the tension wheel and the guide wheel are wound to two processing rollers, and then passed through the guide wheel, the tension wheel and the line wheel, and finally wound on the take-up and pay-off wheel, and the discharge removal method is combined with th...

Problems solved by technology

However, it has the following problems: 1. The wire mesh that adopts the multi-wire cutting method has a greater pulling force on the cutting roller, and the angle between the wire mesh on both sides of each roller of the three-roller structure is small, and the resultant force of the wire mesh is large, which increases the cutting force of the wire mesh on the cutting roller. 2. In the three-roller structure, the third roll is more likely to receive the cutting waste from the upper wire net, which will cause serious pollution for a long time and is more prone to failure; 3. The feeding roller and cutting roller are arranged in parallel, and the distance between them is small. Increased the possibility of jumping and obliquely pulling the diamond wire between the feed roller and the cutting roller; 4. The feed roller and the 2 cutting rollers are arranged at intervals up and down. It produces a large net force on the feed roller, which affects the service life of the feed roller
