Description

The invention relates to rolling production, in particular to devices for stripping the surface of wire segments.

The aim of the invention is to improve the quality of cleaning the surface of the wire segments with the remnants of the terminals by limiting the longitudinal movement of the wire segment in the drive drum and the placement of the cutting elements on the sides of the annular grooves and the bottom of the longitudinal groove made with cutting edges, each in the form of a semicircle with a diameter equal to the diameter stripped sections of wire, and moving along this section of wire.

In FIG. 1 shows the proposed device; in FIG. 2 - the same, transverse section; in FIG. 3 - stripped wire lengths, general view.

A device for cleaning the surface of wire segments contains racks 1 and 2 (Fig. 1), on which the housing 3 is fixedly mounted and the clamp 4 and the shaft 5 are movably fixed. Inside the housing 3, the drive drum is movably located, consisting of two parts 6 and 7, rigidly each associated with its cylindrical cam 8 and 9. which, in turn, are movably seated on the shaft 5. I interact with it by means of keys 10 and 11. Cylindrical cams 8 and 9 through closed curved grooves 12 and 13 are geometrically connected to rollers 14 and 15 rotating on x 16 and 17. fixed in the housing 3. On parts 6 and 7 there are longitudinal grooves 18, coaxially oriented with each other, where the stripped sections of wire 19 (Fig. 1 and 2) are inserted with the remains of leads 20. On parts 6 and 7 drums (FIG. 1) are also available

annular grooves 21. the height of which is made in arithmetic progression with a difference equal to or greater than the diameter of the wire being cut off from the wire segment 19, of terminal 20. For example, for a terminal diameter of 0.8 mm, the arithmetic progression difference is 1 mm, then the height of the annular grooves can be 5.6 7.8 mm, etc., while maintaining the same pitch between them. On the sides of the annular grooves 21 and the bottom of the longitudinal grooves 18 there are cutting edges 22 made in the form of a semicircle with a diameter equal to the diameter of the stripped sections of wire 19. 8 housing 3 has a support 23 (Fig. 2), spring-loaded with a shock absorber 24. The pressing surface of the clamp 4 and the supports 23 facing the drum parts b and 7 are made along a radius equal to the radius of the outer surface of the drums 6 and 7. On the opposite sides of the drum parts 6 and 7, inside the housing 3, limiters 25 and 26 made in the form of a ring are fixedly fixed.

The device operates as follows.

A stripped length of wire 19 is inserted into the longitudinal grooves 18 of parts 6 and 7 / of the drum, with the remnants of the leads 20 down. In this case, the remnants of the terminals 20 are in the annular grooves 21.

By pressing 4, the stripped length of wire is pressed in the longitudinal groove 18. By rotating the shaft 5 resting on the posts 1 and 2, the cylindrical cams 8 and 9 and the drum rigidly connected to them are driven by the keys 10 and 11. . (parts 6 and 7). By rotating the drum, a section of wire 19, sliding along the pressing surface of the clamp 4, is inserted under the inner surface of the housing 3 and the support 23 located therein. In this case, the support 23 presses the length of the wire 19 in the longitudinal groove 18 under the action of the shock absorber 24.

With further rotation of the shaft 5 and cylindrical cams 8 and 9 due to the rollers 14 and 15, rotating on the axes 16 and 17 and located in closed curved grooves 12 and 13, the cylindrical cams 8 and 9 receive additional reciprocating motion in opposite directions along shaft axis 5.

The reciprocating movement from the cylindrical cams 8 and 9 is transmitted to the drum. In this case, the cutting edges 22 on parts 6 and 7 of the drum, moving along the strip of wire to be stripped 19, cut off the remains of the conclusions 20. Since the height of the annular grooves 21 is made in

arithmetic progression and the distance of the cutting edges 22 from the remnants of the conclusions 20 is different, then when the parts 6 and 7 of the drum move in different directions cutting

edges 22, the remnants of the conclusions 20 are cut in parts, in pairs. During stripping, the length of wire 19 is fixed in its movements by stops 25 and 26.

After stripping, wire length 19

pushed out of the longitudinal groove 18 into the container (not shown in Fig.} and processing of another piece of wire 19 inserted into the next longitudinal groove 18 begins.

The quality of the surface cleaning of wire segments on this device is not affected by tolerance fluctuations in the manufacture of the diameter of the wire segment, nor the possibility of introducing the output into the segment

welding wire, i.e. the surface to be cleaned is continuously pressed during processing to the cutting edges that completely repeat its profile. The number of pieces of wire into which the pin is inserted during welding is 10% of the total number of pieces.

High-quality cleaning of such rails allows increasing the frequency of their reuse and obtaining economic

the effect in the amount of 50 thousand rubles per year due to the saving of expensive material of battens, for example tantalum.
