Mosaic nylon bearing shell apparatus of rare earth zinc steel strand

Abstract

The invention discloses an inlaid nylon bearing bush device for a rare earth zinc steel strand, which comprises a cradle, on which a mandrel groove is arranged; a nylon bearing bush is arranged in the mandrel passing groove, and the thickness of the nylon bearing bush is Thickened to 10 mm, the outer edge of the nylon bearing is left to fit with the outer edge of the mandrel groove; the lower part of the outer edge of the nylon bearing is locked by a steel sheet; the inner side of the nylon bearing is higher than The groove surface of the mandrel is 10mm; the invention adopts the triple stability design method of the nylon bearing, which can completely prevent the overturning even after the bearing is worn out, and prevent the jamming of the mandrel and the shaft groove of the cradle wall, and the occurrence of I-shaped wheel flying in the cradle Out of the cylinder safety accident occurred. At the same time, the thickened design of the contact surface between the nylon bearing bush and the mandrel groove not only prolongs the service life of the nylon bearing bush, but also significantly improves the balance of the tension of the I-shaped wheel pay-off, resulting in serpentine steel strand products Quality issues are under control.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular refers to an inlaid nylon bearing bush device for a rare earth zinc steel strand. Background technique [0002] The tube stranding unit has the advantages of high mechanical strength, high production efficiency, low energy consumption, compact structure, stable start-up, and convenient operation. It has been used in the field of cable industry manufacturing for the preparation of copper strands, steel strands, etc. [0003] There are six independent cradles in the existing pipe stranding machine, which are used to place the I-shaped wheels full of steel wires. After the steel wire is filled with the I-shaped wheel, put the I-shaped wheel respectively on the nylon bearing pad slipping gasket in the groove of the cradle I-shaped wheel through the mandrel, and then close the locking pin through the mandrel. The nylon bushing gasket for the I-shaped wheel is placed in the cr...

AI Technical Summary

Problems solved by technology

[0004] However, the thickness of the nylon bearings used in the existing equipment is thin (3mm), small in size, insufficient in stability, poor in wear resistance, and easy to be damaged. The tightness of a steel wire in the steel strand is inconsistent, and the steel strand has a serpentine product quality accident

Secondly, due to the overturning of the bearing bush, it is very easy to cause jamming between the mandrel shaft and the shaft groove on the wall of the cradle, which may cause a serious safety accident in which the I-shaped wheel in the cradle flies out of the cylinder.
