Novel multi-wire cutting mechanism with variable axial spacing

Abstract

The invention provides a novel multi-wire cutting mechanism with variable axial spacing, which comprises a rack, a first wire roller, a second wire roller, a third wire roller, a fourth wire roller and a rotor, wherein the first wire roller, the second wire roller, the third wire roller and the fourth wire roller are respectively driven by four servo motors, the rotor is provided with a fifth wire roller, a sixth wire roller and a seventh wire roller, and the connecting lines of the centers of the fifth wire roller, the sixth wire roller and the seventh wire roller form a triangle; a containing space is formed in the first wire roller, the second wire roller, the third wire roller and the fourth wire roller, and the fifth wire roller, the sixth wire roller and the seventh wire roller are all located in the containing space. The cutting wire net is supported and wound by any two of the first wire roller, the second wire roller, the third wire roller, the fourth wire roller, the fifth wire roller, the sixth wire roller and the seventh wire roller. And the rotor is rotated, so that two different wire rollers in the fifth wire roller, the sixth wire roller and the seventh wire roller serve as working wire rollers to support the lower flat cable net to participate in material cutting, the center distance between the wire nets of the left cutting area and the right cutting area is adjusted, and two different workpieces can be cut at the same time.

Description

technical field [0001] The invention relates to the technical field of cutting equipment, in particular to a new mechanism for multi-wire cutting with variable interaxial spacing. Background technique [0002] The multi-wire cutting machine is a processing equipment that uses a consolidated abrasive steel wire or a high-speed reciprocating steel wire to bring the abrasive into the processing area for grinding. The common cutting materials are mostly brittle and hard materials, such as semiconductor materials (silicon ingots, silicon carbide ), glass and magnetic materials such as NdFeB, etc., the workpiece can be uniformly cut into tens or hundreds of pieces, and the bending degree (BOW) of the multi-wire machine cutting material is small, the warp (Warp) is small, and the parallelism (Tarp) Good, total thickness tolerance (TTV) is small, and cutting loss between sheets is small. [0003] In order to make thinner slices and reduce material loss when cutting materials, multi...

AI Technical Summary

Problems solved by technology

When cutting hard materials, if the center distance of the wire roller is too large, the steel wire will produce a larger wire bow during the cutting process, which will reduce the cutting efficiency, the cutting surface quality will be poor, and it is easy to break the wire during the cutting process; the center of the wire roller If the pitch is too small, the size of the cutting workpiece will be limited, large warpage will occur when cutting thin slices, the risk of wire breakage will also increase, and the utilization rate of the machine tool will be limited
