Embodiment Construction

[0014] See attached figure 1 , 2 , a multi-wire cutting machine shown in the embodiment of the present invention, it at least includes a bed, a working panel, a rear panel, three sheaves 12, 13, 14 distributed in the shape of a finished product are installed on the working panel, and the rear panel is installed There are pay-off wheel 1, take-up wheel 24, and a guide wheel 2 and four guide wheel connecting rods are also installed on the rear panel, which are respectively 25, 26, 27, 28, and one is respectively installed on both sides of each guide wheel connecting rod. The guide wheels are respectively guide wheels 3, 4, 5, 6, 20, 21, 22, 23, and there are also a plurality of reversing wheels 7, 8, 9, 10, 11, 15, 16, 17, 18, 19, after steel wire is released by pay-off wheel 1, guide wheel 2, guide wheel 3, 4, 5, 6, multiple reversing wheels 7, 8, 9, lead to the front working panel successively, and Through the reversing wheel 10, it is wound around three sheaves 12, 13, 14 ...

Abstract

The invention relates to a multi-wire cutting machine which at least comprises a bed, a working panel and a rear panel. Three sheaves which are distributed to form a pyramid are mounted on the working panel, a pay-off wheel, a take-up wheel and four guide wheel connecting rods are mounted on the rear panel, two guide wheels are respectively mounted on two sides of each guide wheel connecting rods, a plurality of reverse wheels are further arranged among the sheaves and the guide wheels, and steel wires are paid off by the pay-off wheel, then sequentially pass a guiding wheel, the multiple guide wheels, the reverse wheels and the three sheaves and form a group of parallel steel wires, and then the group of parallel steel wires is led out of the sheaves and is guided to the take-up wheel via the multiple reverse wheels and the multiple guide wheels to be closed. The multi-wire cutting machine is characterized in that the lengths of the guide wheel connecting rods which are far away from the pay-off wheel and the take-up wheel are at least two times the lengths of existing guide wheel connecting rods, and the lengths of the guide wheel connecting rods which are close to the pay-off wheel and the take-up wheel are at least 1.3 times the lengths of the existing guide wheel connecting rods. The multi-wire cutting machine has the advantages that the distances among the adjacent guide wheels are increased to a great extent, so that stress on the steel wires among the adjacent guide wheels can be effectively relieved, tension on the steel wires is uniform, and the steel wires are not easy to break.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a multi-wire cutting machine. Background technique [0002] The multi-wire cutting machine is a kind of cutting machine tool that brings the abrasive into the processing area through the high-speed reciprocating motion of the wire, grinds the workpiece, and cuts the workpiece into hundreds of thin slices at a time. The multi-wire cutting machine has become a non-metallic cutting machine. An important tool for material cutting and processing, often processing silicon wafers and various hard and brittle materials. The cutting edge on the steel wire rubs against the silicon rod to achieve the cutting effect. Multi-wire cutting machine has the advantages of high efficiency, high production capacity and high precision. The broken wire of multi-wire cutting machine is a common problem that cannot be ignored. There are many reasons for the broken wire. In the prior art, the length o...
