Reciprocating cutting device

Abstract

The invention discloses a reciprocating type cutting device which comprises a rack and a diamond wire, wherein a driving roller and a driven roller opposite to each other are arranged on the rack; the diamond wire is twined between the driving roller and the driven roller; the driving roller and the driven roller are connected with two support plates; a base is connected onto the rack in a sliding manner; the two support plates are connected onto the base in a sliding manner; the sliding direction of the base is perpendicular to that of the two support plates; threaded holes with opposite screwing directions are formed in the two support plates; the reciprocating type cutting device further comprises two screw rods, and threaded sections of the two screw rods have opposite screwing directions; internal threads of the two threaded holes are in threaded connection with the corresponding threaded sections of the screw rods; a cam is propped against one side, in the sliding direction, of the base; a tongman is arranged above the diamond wire and is connected with a push rod; the push rod is connected onto the base in a sliding manner; through matching of the threaded holes and the screw rods, the tension degree of the diamond wire can be conveniently adjusted, and after the tension degree of the diamond wire is increased, the cutting intensity of the diamond wire can be ensured, and the diamond wire can cut polycrystalline silicon more easily, so that the cutting efficiency is improved.

Description

technical field [0001] The invention relates to a cutting device, in particular to a reciprocating cutting device. Background technique [0002] Many things in the industry are cut with diamond wire, such as polysilicon slices in the photovoltaic field. The material of the diamond wire is important. At present, the mainstream silicon wafer cutting wire used in the photovoltaic field is an ultra-fine cutting steel wire with a diameter of about 100 microns. As the name suggests, diamond wire is related to diamond. It is generally a diamond cutting wire made of tiny diamond particles embedded on the wire; we know that diamond is a superhard and widely used cutting material. Serrated teeth, which increase the cutting ability of the steel wire, can greatly speed up the cutting speed. [0003] When using cutting wire to cut polysilicon, the diamond wire is first fixed on the reciprocating cutting device. The reciprocating cutting device includes a frame, and two rollers are fix...

AI Technical Summary

Problems solved by technology

[0004] The problems of the above devices are: 1. When installing the diamond wire, because the distance between the two rollers cannot be adjusted, it is impossible to ensure that the installed diamond wire is at a high tension; When cutting polysilicon, the diamond wire cutting strength cannot be guaranteed, which will lengthen the cutting time and affect the cutting efficiency
