Description

one

The invention relates to metallurgy, in particular, devices for applying lubricant and coatings on ropes, cable cables, wires and other profiles of various configurations.

Rope lubrication devices are known that contain a rigid-walled chamber in which a lubricant is supplied to the product under pressure or by transferring a roller, thereby creating direct contact of the roller with product II.

The disadvantages of the known rope lubrication devices are the frequency of their operation during the delivery of a highly viscous lubricant under pressure or poor application of the lubricant due to incomplete lubrication.

Closest to the invention is a device for lubricating crane cargo ropes, comprising a bath with rigid walls, with an inlet and an outlet wipe and lubricant and activator rollers 2 accommodated therein.

The disadvantages of the known device are the low quality of lubricant applied to the product and the impossibility of applying highly viscous lubricating materials due to the design of lubricating roller elements, which during rotation in a highly viscous lubricant form a groove in which the subsequent rotation does not adhere to the roller surface . In addition, when changing the type of lubricated product, it is necessary to replace the rollers, which requires a considerable amount of time for assembly operations.

The purpose of the invention is to increase the quality of the application of a highly viscous lubricant to the product.

This goal is achieved by supplying the device with a carriage installed with the possibility of cyclic movement parallel to the axis of the product, making the bath walls of elastic material, for example, oil-resistant rubber, installing activator rollers on the outside of the walls on the carriage, with the possibility of interacting with the elastic bath walls.

FIG. 1 shows a device for applying lubricant to long products; in fig. 2 - bath with lubrication, longitudinal section; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one.

A device for applying lubricant to lengthwise products comprises a bath 1 with an inlet 2 and an outlet 3 wipers and lubricant 4, side activator rollers 5 and lower rollers activators b mounted on a carriage 7, having the possibility of cyclic movement parallel to the axis of the product from the drive 8. Walls Bath 1 is made of elastic material, such as oil-resistant rubber, plastic film, PVC film or rubberized fabric. In the upper part of the bath 1 there are discharging openings 9 with lids 10.

The device works as follows.

Through the loading openings 9, the bath 1 is completely filled with lubricant 4. The rollers-activators 5 and 6 together with the carriage 7 from the drive 8 cyclically move from the inlet wipe 2 to the outgoing wiping 3 and back, while the lubricant 4 accumulates in the outer zones of the wipers 2 and 3, which provides for the forced continuous lubrication of the surface of the product in the zone of rollers 2 and 3 and in the zone of rollers 5 and 6 due to y1) e. (Considering the density of adhesion of the lubricant to the product due to the change in the shape of the bath in

the area of rollers 5 and 6. The excess lubricant 4 is removed by the output wipers 3, and under the action of the moving rollers-activators 5 and 6 through the free space between the walls of the bath 1 and the articles moving from the wiper 2 towards the center of the bath 1.

The proposed device provides an increase in the quality of cable lubrication by 60% compared with the known ones and a reduction in the complexity of the process of lubricant delivery by 30%.
