(54) MACHINE FOR CLEANING AND WINDING WIRES

one

The invention relates to the processing of metals by pressure, in particular to the processing of welding wire.

A device for rewinding and cleaning electrode wire, comprising an unwinder and a winder, between which is placed a cleaning unit made in the form of a steel cable, one end of which is fixed and the other is connected with a sleeve around the longitudinal axis of the wire for helical winding this electrode wire bushing.

The disadvantage of this construction is poor cleaning of small diameter wires.

Also known is a machine for cleaning and winding a wire, which contains an accessory drum, a wire cleaning unit with a pair of abrasive wheels, and a cassette for winding a wire. And a wire laying mechanism.

However, cleaning a wire of small diameters with a known device is made difficult by its frequent breaks due to considerable efforts that occur when the wire is pulled through twisted steel branches.

cable. When weakening the tension of the cable, the quality of wire cleaning decreases. In addition, the node fine cleaning of the known device also does not provide the required quality of processing the wire with a diameter different from the size of the profile of grooves on the periphery of abrasive wheels. For high-quality cleaning in this case, a change of abrasive wheels with the installation of wheels with profile grooves corresponding to the size of the wire is required, and this reduces the cleaning performance and the degree of universality if it is necessary to process wires of equal diameters.

The aim of the invention is to increase productivity and improve cleaning quality.

This goal is achieved by the fact that a machine for cleaning and winding a wire containing an accessory drum, a wire cleaning unit with a pair of abrasive wheels, and

20 also the wire cassette and its associated pick-up mechanism are provided with an additional cleaning unit with a wire cassette and a pick-up mechanism, with both the winding cassettes mounted coaxially and both the pick-up mechanisms also coaxially to each other. The cleaning unit is made in the form of several pairs of abrasive wheels, with two pairs of abrasive wheels arranged in series at different angles of inclination of the end surfaces of the circles of one pair relative to the other, and one of the abrasive wheels of each pair is spring-loaded in the axial direction. FIG. 1 shows a machine, a general view; in fig. 2 shows a section in FIG. one; in fig. 3 is a diagram of wire coverage with abrasive circles. The machine contains two winding drums 1 cleaning unit 2, a winding device 3, cassettes 4 for winding wire 5 connected to drive 6. On the viewing drums bays 7 are installed with wire 5. Cleaning node 2 is made in the form of successively arranged at an angle to each other pairs of 8 coaxially mounted abrasive wheels 9. One of the circles of each pair is spring-loaded by a spring 10 along axis 11, on the other hand the spring 10 abuts against nut 12. Guides 13 are installed at the inlet of the cleaning unit and at its exit eynoe movement of the wire through this site. The layout mechanism 14 is associated with a cassette drive. The machine works as follows. The coils 7 with the wire 5 are mounted on the viewing drums 1. The free ends of the wire 5 are passed through the guides 13 and are pulled through the cleaning unit. 2, then directed to the cassettes 4. When Z ,, OU J V.1V1 L iipa oi / i / i ivji / ii-iv-iv-f, when the drive 6 is turned on, the cassette 4 begins to rotate the pull wire 5 through the cleaning unit 2 When laid out in successive yarns, in the winding device 3, the wire is wound evenly on two cassettes 4. In the cleaning unit, the wire 5 is covered with abrasive wheels 9 around the entire circumference. This is achieved

Claims (2)

lO - HH eat, that the axes of each pair of abrasive wheels 9 are inclined at an angle I to each other. The angle L is selected according to the required cleaning quality and wire diameter. The total rotation angle of the axis 11 is 180-175 °. With the passage of the wire 5 between the abrasive circles 9, it produces a groove in their ends, which contributes to a better coverage by its circles. The amount of clamping force of the wheels 9 is adjusted by the nut 12. If necessary, wires of different diameters can be processed simultaneously on the wall. For this, cassettes are installed in which the length of the wire being wound is the same. The use of the proposed machine for cleaning and winding welding wire allows improving productivity, yjJe reliability and improving the quality of cleaning small diameter wires.
