Description

The invention relates to devices for cleaning the surface of a wire from an oxide film and rust and winding it into skeins for welding and surfacing machines, it is an improvement of the invention according to the author. St. NS 1181733.

The known device for cleaning and winding the wire contains a cleaning unit mounted on the housing, a laying mechanism and a winding mechanism including a receiving and filling cassettes. The cassette is equipped with a brake.

A disadvantage of the known device is the winding of the wire to be cleaned on the receiving cassette directly from the coil, laid on the refueling cassette of the winding mechanism. This leads to uneven operation of the winding mechanism, causes uneven descent of the loops and entanglement of the wire.

The purpose of the invention is to increase reliability.

This goal is achieved by the fact that the device according to ed. St. Mg 1181733 contains a pre-cleaning unit mounted on the housing with a spinneret, a node with cleaning elements, a wire laying mechanism with a spinneret and a receiving cassette, and a winding mechanism including a filling cartridge with a braking device. The reel cassette of the winding mechanism is made in the form of a backing disc with an outer flange connected to the disc of the braking device. A cone with a cone flare is mounted on the backing disc on its smaller base aside from its

center. The pre-cleaning unit spinneret is mounted on the housing with its longitudinal axis located tangentially to the perimeter of the smaller base of the cone.

The filling cassette of the winding mechanism in the form of a backing disc with an outer flange and with a truncated cone with a conical flange mounted on the basic disc and the location of the perimeter line of the smaller cone base tangentially to the longitudinal axis of the spinneret ensures free removal of the wire directly from the coil with constant tension between filling and receiving cassettes, regardless of the mode of gathering wire loops from the bay excluding slipping of coils and tangling of the wire, which increases reliability.

FIG. 1 shows the proposed device, a general view; in fig. 2 - refill cassette (transverse axial section) with the laid bay of the wire to be cleaned; in fig. 3 - filling cartridge, plan view.

The device for cleaning and laying the wire comprises a housing 1 (FIG. 1), on which a filling cartridge 2, a pre-cleaning unit 3, an assembly 4 with cleaning elements, and an attendant mechanism 5 for laying the wire 6 with a receiving cartridge 7 are placed. 5, the laying of the wire with the cassette 7 constitutes the winding mechanism. The refueling cassette 2 is mounted on the upper part of the housing 1 and is designed to install and fix the coil 8 (Fig. 2) of the wire 6. The cassette 2 includes a rotary bearing disc 9 with a truncated cone 10 coaxially mounted. The disk 9 has an outer flange 11, and the cone 10 is made with a tapered flange 12 along the line 13 (FIGS. 2, 3) of the perimeter of the upper (smaller) base 14, directed away from the center of the latter. Cone 10 is rigidly connected to the disk 15 of the brake device. The cassette 2 is installed so that the level of the upper base 14 of the cone 10 coincides with the axis 16 of the cleaning unit 4, and the spinner 17 of the pre-cleaning unit 3 is mounted with its longitudinal axis 16 along the tangent to the perimeter line 13 of the smaller base 14, The brake disk 15 is mounted with the possibility of periodically interacting with the friction lining 18. The force of pressing the lining 18 to the disk 15 is adjusted by the handle 19 by means of the spring 20 through the disk 21.

The proposed device works as follows.

The coil 8 of the wire to be cleaned 6 is laid on the filling cassette 2 mounted on the housing 1 (Fig. 1). The wire b is threaded into the pre-cleaning block, is passed through the assembly 4 with cleaning elements and an attendant installation 5 of the wire 6 and is wound onto the receiving cassette 7 of the winding mechanism. The coil 8 is centered by a cone 19 and

0 is held on the swiveling bearing disc 9 by an outer flange 11. Before filling the wire 6 into the die plate 17 of the pre-cleaning unit 3, several are wound onto the truncated cone 10 (for example,

5 at least three turns of the wire to be cleaned and the braking device is adjusted. The coils of wire 6 are formed on a truncated cone 10 by rotating the cassette 2 in the direction opposite to

0 labor movement. The adjustment of the braking device is made by turning the knob 19 (Fig. 2). In this case, compression (stretching) of the spring 20 is performed, which through the disk 21 strengthens (weakens) the force

5, the interaction between the friction pad 18 and the disk 15. The coils of the wire 6 formed on the cone 10 by successive removal of loops from the coil 8, as the cassette 2 rotates, it rises to the top

0 base 14, and the wire 6 tangentially N to the line 13 of its perimeter with constant tension enters the die plate 17 of block 3.

Execution of the refueling cassette of the winding mechanism in the form of a supporting disk with

5 an outer flanging and a truncated cone with a conical flanging mounted on the supporting disc, and the location of the perimeter of the smaller base of the cone tangential to the longitudinal axis of the spinneret allows not

0 only to increase the reliability of the device by eliminating entanglement and wire breakage, but also to simplify the design, i.e. reduce metal consumption. In addition, the invention makes it possible to increase productivity by increasing the unwinding speed, commensurate with the speed of cleaning the wire, and reducing the time lost to eliminate the effects of wire breakage and entanglement.
