Tungsten wire rope winding machine

Abstract

The invention relates to a tungsten wire rope winding machine which is provided with a rack, wherein an unwinding bracket for a raw wire winding drum to be placed is arranged at one end of the rack, and a twisting mechanism for winding raw wires in a stranding mode is arranged on one side of the unwinding bracket. The other side of the twisting mechanism is provided with a mechanical molding mechanism, a dragging mechanism and an automatic winding and wiring mechanism in sequence. The tungsten wire rope winding machine can fully meet the requirement that a tungsten wire rope is not deformed due to heating in a single crystal furnace under an operating temperature of about 1500 DEG C, so that the service life of the tungsten wire rope is prolonged by dozens of times compared with that of a steel wire rope (the steel wire rope is 3-7 heats, and the tungsten wire rope can reach 50-70 heats).

Description

technical field [0001] The invention belongs to the technical field of preparation of special tungsten wire ropes for crystal growth equipment. Background technique [0002] When pulling a single crystal, a pulling flexible shaft is required, which is composed of hundreds of fine tungsten wires or stainless steel wires. With the improvement of methods and technologies for pulling single crystals, the traditional use of stainless steel wire ropes is no longer suitable for the high-quality drawing environment, and its high temperature resistance, tensile strength, service life, etc. have not reached modern pulling equipment. requirements. Therefore, the flexible shaft used in crystal growth equipment is most suitable to use the right-hand twisted tungsten wire rope as the flexible shaft. Because the tungsten wire rope has high rigidity, low torsional stress, non-rotating characteristics, high temperature resistance, non-magnetism, super softness, fatigue resistance, corrosio...

AI Technical Summary

Problems solved by technology

This also puts forward higher requirements on the pulling force of the wire rope; in addition, the working temperature in the single crystal furnace is 1500°C, and the service life of the wire rope is difficult to meet the user's requirements; if the wire rope is suddenly interrupted during the crystal pulling process, it will The collapse of the pot caused the direct economic loss of more than hundreds of thousands of yuan.

[0009] Therefore, in response to the technical requirements of the soft shaft in the "lifting system" - silk rope, such as high strength, high tensile force, non-magnetic, high temperature resistance, and excellent verticality, after the unremitting efforts of foreign developed countries, the United States and Japan have successively developed "Tungsten wire rope" is a high-tech product made of special materials. Due to the constraints of material technology in China, it has not yet achieved self-production and self-use.
