Mosaic nylon bearing shell apparatus of rare earth zinc steel strand

Abstract

The invention discloses a mosaic nylon bearing shell apparatus of rare earth zinc steel strand. The mosaic nylon bearing shell apparatus of rare earth zinc steel strand includes a cradle, wherein a core-through shaft groove is formed in the cradle; a nylon bearing shell is arranged in the core-through shaft groove; the thickness of the nylon bearing shell can be increased to 10mm; the outer edge of the nylon bearing shell is provided with a bead which matches the outer edge of the core-through shaft groove; the lower part of the outer edge of the nylon bearing shell is locked and fixed by a steel disc; and the inner side of the nylon bearing shell is 10mm higher than the core-through shaft groove surface. For the mosaic nylon bearing shell apparatus of rare earth zinc steel strand, througha triple stability design method of the nylon bearing shell, even if the bearing shell is worn, the bearing shell can completely block occurrence of overturn and prevent the clamping and blocking situation between the core-through shaft and the cradle wall shaft groove so as to prevent occurrence of safety accident that a spool in the cradle flies out from the cylinder; and at the same time, thickening design is performed on the contact surface between the nylon bearing shell and the core-through shaft groove, thus prolonging the service life of the nylon bearing shell, significantly improving the proportionality of the line laying tension of the spool, and controlling the caused product quality problem that the steel strand becomes snake-shaped.

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.
