Description

Round tight strand anti-abrasion device for carrier cable gauge

Technical Field

The utility model relates to a be used for tight strand wear prevention device of carrier cable rule circle belongs to contact net carrier cable technical field for the electronic railway.

Background

In the prior art, the catenary of the domestic electrified railway contact network is mainly formed by stranding copper-magnesium alloy single wire cores in multiple layers, and the contact wire is suspended by a dropper line and is supplied with power in parallel with the contact wire, so that the process quality of the catenary is controlled very important during production.

When a planetary stranding machine is used for producing a catenary of a contact network, each stranding cage single line is deformed by a pre-deformer at rated tension and speed, then passes through a die made of a composite material and a horizontal and vertical roller, and the pressure of a wheel is manually adjusted to prevent the catenary from stranding;

the manual adjustment of the wire pressing force is not uniform, so that the quality defects of serious abrasion of the carrier cable, snakelike bending, irregular round cross section, strand scattering and the like are finally caused, and the cost is greatly wasted because the carrier cable is turned over and scrapped when the quality defects are serious.

Therefore, there is an urgent need for a device that will make the surface of the messenger wire smooth, round in cross-section, and free from strand unraveling during the actual production of the messenger wire.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem of proposing in the above-mentioned background problem, provide one kind and be used for tight strand wear prevention device of carrier cable rule circle, it can solve at the in-process carrier cable of actual production serious, snakelike curved, the quality defects such as non-rule circle in cross-section, strand scattered of wear loss have increased the mould life-span simultaneously, improve mechanical efficiency, practice thrift the cost.

The purpose of the utility model is realized like this: the round tight strand anti-abrasion device for the carrier cable gauge comprises a die insert upper part and a die insert lower part, wherein the die insert upper part and the die insert lower part integrally form an oblique half-and-half split die which is rectangular as a whole;

self-lubricating bearing bushes are arranged on the upper part of the mould insert and the lower part of the mould insert and are combined up and down to form a circular hole;

a plurality of holes are uniformly distributed in the self-lubricating bearing bush, ball grooves are formed in the upper portion of the die insert and the lower portion of the die insert in a matched mode, and balls are mounted in the corresponding positions of the hole positions.

The ball is embedded between the self-lubricating bearing bush and the oblique half-split mold.

The diameter of the hole in the self-lubricating bearing bush is smaller than that of the ball.

The oblique half-splitting body die is installed on the die box.

Compared with the prior art, the utility model discloses a be used for tight strand wear prevention device of carrier cable rule circle has following advantage:

the utility model discloses a be used for tight strand wear prevention device of carrier cable rule circle, when carrier cable production, it is fixed to two oblique half-and-half segmentation body moulds through the mould box, compress tightly carrier cable simultaneously, because of the self-lubricating axle bush of equipment in the mould and inlay the ball, the ball can produce universal motion, self-lubricating ability is strong, wear resistance is good, can become rolling friction with traditional sliding friction, the frictional force that carrier cable produced when making circumference and linear motion in the mould is very little, move under a plurality of ball uniform pressure effects simultaneously, can protect carrier cable surface better not receive wearing and tearing, cross-section rule circle and not scattered strand, increase the mould life-span, mechanical efficiency is improved, greatly save the cost.

Detailed Description

The invention is described below with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 to 4, the round tight strand anti-abrasion device for the carrier cable comprises a die insert upper part 1 and a die insert lower part 4, wherein the die insert upper part 1 and the die insert lower part 4 integrally form an oblique half-and-half split die which is rectangular as a whole;

self-lubricating bearing bushes 5 are arranged on the upper part 1 of the die insert and the lower part 4 of the die insert, and are combined up and down to form a circular hole;

a plurality of holes are uniformly distributed in the self-lubricating bearing bush 5, ball grooves are formed in the upper portion 1 of the die insert and the lower portion 4 of the die insert in a matched mode, and balls 2 are mounted in the corresponding positions of the hole positions.

The ball 2 is embedded between the self-lubricating bearing bush 5 and the oblique half-split die.

The diameter of the hole on the self-lubricating bearing bush 5 is smaller than that of the ball 2.

The oblique half-splitting body die is arranged in the die box.

In this embodiment, the utility model discloses a wear-proof device for round tight strand of carrier cable gauge, which is to assemble self-lubricating bearing bushes 5 in the upper part 1 and the lower part 4 of the die insert, and to match with the embedded balls 2;

the ball 2 can generate universal motion, has strong self-lubricating capability and good wear resistance, and changes the traditional sliding friction into rolling friction;

the force of friction generated when the carrier cable makes circular and linear motion in the oblique half-and-half split die is very small, and the carrier cable moves under the action of uniform pressure of a plurality of balls.

The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
