Description

(54) DEVICE FOR LAYING WIRES AT PANEL

I

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

A device for laying a wire into two coils is known, comprising a folding tube and a mechanism for its movement, made in the form of a hydraulic cylinder 1.

The disadvantage of this device is low productivity, due to the fact that the wire is first laid out on one of the coils, after filling in which the hydraulic cylinder moves the pickup tube to the area of the second coil, and the filling of the second coil begins.

It is also known a device for laying out wire when winding on two coils, containing pick-up rollers and a mechanism for moving them 2J.

A disadvantage of this device is its complexity, since each separate pickup roller has its own separate movement mechanism.

The aim of the invention is to simplify the design.

The goal is achieved by the fact that in the device for laying out the wire when winding on two coils containing the folding rollers and the mechanism for moving them, the moving mechanism is made in the form of a folding cam installed with

5 the possibility of contact with the folding cam of two pushers and the spring-loaded double-arm levers associated with them; the folding rollers are mounted on one of the ends of each two-shoulder

.- levers.

FIG. 1 shows the proposed device; in fig. 2 shows section A-A in FIG. 1 The device contains a folding cam 1 mounted on the shaft 2 of the drive 3. With the cam 1 contact two shooters J5 l 4, which are diametrically opposed. Each of the pushers 4 is made in the form of a rod 5 of a rectangular cross section located in the guides 6 and the break-in roller 7 which is hinged to it.

20 Pushers 4 are in contact with the ends of the two shoulders 8, which are identical in shape, but are mirrored relative to each other. Each of the levers 8

hinged on support 9. At the other ends of the levers 8, the wings 10 are hinged, containing folding rollers 11. The ends of the levers 8 in contact with the pushers are interconnected by a spring 12, the wire 13 is passed through the folding rollers 11 to the rollers 14.

The device works as follows.

Drive 3, via shaft 2, causes rotational movement to cam 1. Rolling profile of rotating cam 1 with rollers 7, pusher 4 receives a reciprocating movement along guides 6, and transmits this movement to levers 8 with free ends. moving the wings 10 with folding rollers I, along which the wire 13 moves, being laid out in successive turns on two rollers simultaneously 14. The connection of the levers 8 by a spring 12 ensures The constant contact of these levers with the pusher 4 and the pushers with the profile surface of the cam 1.

The use of the device allows one drive to be used to lay the wire into two coils at once.
