Wire regulating device of multi-wire cutting machine steel wire

Abstract

The invention discloses a wire regulating device of a multi-wire cutting machine steel wire, which is used for increasing a cutting thickness range of a multi-wire cutting machine. The wire regulating device comprises a left cutting roller and a right cutting roller which are arranged on a front fixing board and a rear main board, wherein the size, the wire groove number and the groove distance of the left cutting roller are the same as those of the right cutting roller. The wire regulating device is characterized in that the rear main board is provided with a guide wheel installation board, the guide wheel installation board is respectively provided with a wire inlet guide wheel set and a wire outlet guide wheel set, a steel wire is vertically led out from a first wire groove of the left cutting roller, the steel wire is then pitched in a first guide wheel on the wire inlet guide wheel set, the steel wire is then pitched in a first guide wheel on the wire outlet guide wheel set, the first guide wheel on the wire outlet guide wheel set is coplanar with the first guide wheel on the wire inlet guide wheel set, the steel wire is then vertically pitched in a second wire groove of the right cutting roller, and thus the groove replacement of the steel wire is completed. According to the wire regulating device disclosed by the invention, bad phenomena of wire jumper and eccentric wear of the cutting rollers, which are caused by an overlarge span angle between the grooves of the cutting rollers due to overlarge distance between the V-shaped circular grooves on the cutting rollers, are prevented from happening, the product processing accuracy is ensured, and the processing cost is saved.

Description

technical field [0001] The invention relates to a multi-wire cutting machine, in particular to a wire adjusting device for the steel wire of the multi-wire cutting machine. Background technique [0002] Multi-wire cutting machine is mostly suitable for the processing of thin slices of hard and brittle materials such as semiconductors. For thin slice materials with a cutting thickness of only 0.1㎜~5㎜, multi-wire cutting machine cutting is a high-efficiency, high-precision, and easy-to-operate method. processing methods. Because the cutting rollers are provided with V-shaped ring grooves of the same size and same spacing, the spacing between the V-shaped ring grooves determines the thickness of the cutting sheet, and the number of V-shaped ring grooves determines the number of one-time forming sheets of the cutting sheet. Therefore, when cutting materials with a thickness exceeding 5mm, the steel wire 14 is likely to form a cross angle when jumping from one V-shaped ring groo...
