Bidirectional wire arranging device of multi-wire cutting machine and control method of bidirectional wire arranging device

Abstract

The invention provides a bidirectional wire arranging device of a multi-wire cutting machine and a control method of the bidirectional wire arranging device, belongs to the technical field of machinery and solves the problem that cut wires are easy to break due to the fact that wires of existing multi-wire cutting machines are not arranged in place. Two bidirectional wire arranging devices of the multi-wire cutting machine are arranged between a winding and pay-off reel and a tension control pulley, and each of the two bidirectional wire arranging devices is provided with a mounting support, a driving mechanism, a wire arranging guide mechanism, two detecting wheels and a controller, wherein the two detecting wheels are arranged on the mounting support side by side and arranged on two sides of a cutting line, and each detecting wheel is provided with a pressure sensor connected with the controller. By sensing the position of the cutting line through the pressure sensor and adjusting speed of the driving mechanism through the controller, in-place wire arrangement is guaranteed. Besides, the bidirectional wire arranging device is simple in structure, convenient to control and high in accuracy.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a multi-wire cutting machine, in particular to a bidirectional wire arrangement device and a control method for the multi-wire cutting machine. Background technique [0002] At present, the cutting principle of a multi-wire cutting machine for high-precision thin-sheet cutting of hard and brittle materials is that the cutting wire rotates forward and backward repeatedly at high speed, bringing the abrasive into the processing area to achieve cutting. During the process, due to the cutting wear, the cutting wire is gradually collected to the take-up drum by using the wire arranging device. That is to say, in this process, due to the wear and tear of the cutting wire, the time for the forward rotation of the pay-off drum to pay off the wire is always greater than the reverse take-up time. When the pay-off reel rotates forward, the cutting wire will be rewound according to the orig...

AI Technical Summary

Problems solved by technology

The irregularity of the winding of the new wire on the pay-off drum and other reasons of the multi-wire cutting machine itself lead to more irregular new wires on the pay-off drum. The cutting wire slips out of the guide wheel, the wire is shaken greatly when the wire is arranged, the wire is unevenly arranged, and the wire is easily stacked when the forward and reverse direction is changed, and even the bad consequences of the broken wire are caused.
