(54) DEVICE FOR WELDING WIRE CLEANING

one

The invention relates to mechanical engineering, and more specifically to cleaning welding wire from rust and other surface contamination.

A device for cleaning welding wire is known, comprising a housing with upper and lower lids, an abra, ziv chamber inside the housing, elastic walls, and an elastic pipe embedded in the upper housing cover directed to move the wire to be cleaned with dies and a working agent supply system for pressing, abrasive to the wire to be cleaned, connected by means of a nozzle with a wall 1.

A disadvantage of the known device is the inability to change the abrasive layer which is boundary with the wire surface to be cleaned and stirring it, which degrades the quality of cleaning and reduces the productivity of the device.

The purpose of the invention is to improve the performance and quality of cleaning.

This goal is achieved in that a device comprising a housing with upper and lower lids, an abrasive chamber located inside the housing, having elastic walls, and an elastic pipe, a guide built into the upper housing cover for moving the cleaned wire with dies, and a working agent supply system clamping the abrasive to the wire to be cleaned, connected to the wall of the casing by means of a nipple, has additional guides with dies, and an elastic pipe is installed 10 inside the chamber and connected to the system supplying a working agent for pressing the abrasive to the wire to be cleaned.

In this case, the bottom flap of the corlus has openings communicated with the working agent supply system.

In addition, the additional guides are spring-loaded and have conical closures.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The device for cleaning the welding wire consists of a cylindrical body 1, the upper 2 and the lower 3 lids of the chamber 4 with elastic walls 5 filled with an abrasive elastic tube 6 located inside, three chambers 4, the ends of the first

of which are rigidly connected to the housing and the flanges, and the second with washers 7, mounted on the rod 8, and plugs 9, preloaded nuts 10. Elastic cylindrical tubes 5 and 6 form an annular container II and air cavities 12 and 13. On the top cover 2 is reinforced a bunker 14 with guides 15 installed inside it in the form of tubes, at one end of which replaceable filters 16 are fixed, and on the other there are flanges holding the cone closures 17 with help of the spring 18 in the closed state. On the bottom cover 3 fixed additional cover 19, made in the form of glass. Covers 3 and 19 have diametrically located holes coaxially with directions 15, in which replaceable dies 20 are installed, through which cleaned wires 21 are passed. Lower flange 3 has openings covered by air-permeable washers 22 from below. Ring joint between upper flange 2 and bottom of hopper 14 is covered with an annular air-permeable gasket 23. Air cavities 12 and 13 are connected by means of holes in the rod 8 to the fitting 24 to the working agent supply system 25 for pressing the abrasive to the cleaned wire, from which also there outlet to the nozzle 26 attached to the cover.

The device works as follows.

The welding wires 21 are inserted into the guides 15 through the filters 16 and then, overcoming the force of the spring 18, the guides 15 are aligned with the spinnerets 20, pulling the wire through them. The cone-shaped closures 17 are also lowered down and the annular container 11 is filled with abrasive 4 through the holes in the base of the hopper 14. After that, the guides 15 with the cone-shaped closures 17 are returned to their original state in which they are held by springs 18. Air from supply system 25 The working agent is fed into the cavities 12 and 13. By acting on the inner and outer surfaces of the chamber, it deforms the annular container 11, seals the abrasive 4 and crimps the drawn wires 21 evenly, clearing them. In the cleaning process for changing contaminated, borderline

with wires, a layer of abrasive, compressed air is briefly supplied through the holes in the bottom cover 3, covered with air-permeable washers 22, and through the fitting 24 in the housing 1 and the holes in the rod 8, air is blown out of

cavities 12 and 13 into the atmosphere. The abrasive 4 inside the annular container 11 is agitated. Then again the cavities 12 and 13 are filled with air, and the cycle is repeated. The abrasive is unloaded through the holes formed after dismantling the cover 19 and the interchangeable nozzles 20.
