Description

one

The device for unwinding wire belongs to the field of metal forming and can be used in wire drawing shops.

A device for unwinding a wire, known as a figurine, made in the form of a basket holding a reel of wire, consisting of two joined halves, one of which is mounted for rotation of the pulling, is known. one.

The disadvantage of this device is that the coiling of the wire is carried out through a coaxial guide that is rendered for a considerable vertical distance upwards, which is due to its large dimensions, and besides, the peeling device is not provided with a brake, because of the inertia of the leash , in the case of an instantaneous stopping of the power device, it leads to its entanglement and breaks.

It is also known a device for unwinding, containing a fixed holder and decoiler with a driver and a spring-loaded shoe for pressing down the material to be unwound 2.

The disadvantage of this device is that it does not ensure the retention of turns of frameless wire coils wound in a pile with its axial feed.

The purpose of the invention is to hold

turns of a frameless coil with axial winding of the wire from entanglement.

This is achieved by the fact that the mechanism of clamping the turns of the wire is made in the form of a spring-loaded two-arm movable relative to the leash, a base-arm mounted on one arm of the lever and fixed on the second arm of the diverting roller lever.

FIG. 1 shows the device, a common fork; in fig. 2 is a view along arrow A in FIG. one.

The device consists of a coil holder 1 and an uncoiler 2, made in the form of a leash 3 mounted in a rotary axis 4. Axis

4 jointly with the leash 3 and the tap-off unit

5 are installed rotatably around the coil holder 1. On the driver 3, a two-lever lever 6 is mounted for movement, at one end of which a shoe 8 is fixed on the axis 7. The surface of the shoe 8, which interacts with the surface of the unwinding plate 9, is located at the winding point of the wire. The double-shouldered lever 6 on the second shoulder is provided with a bypass roller 10 and is associated with torsion springs 11. The springs are fixed by turning rings 12 with stoppers 13 and mounted on a leash 3.

The device works as follows. On the Bayer 1 install Bay 9. Pass the end of the wire iodine. shoe

8 and, through the bypass blocks 10 and 5, adjust the force of pressing the shoe 8 by rotating the rings 12 around the axis of the driver 3, followed by fixing them with screws 13. The drive for moving the wire is turned on. Under the action of tensioning the wire, the leash 3 will turn on axis 4 and remove the wire turn by turn. In this case, the torsion springs 11 press the shoe 8 against the surface of the coil 9 at the point of winding the wire.

After turning off the drive and loosening the tension of the wire, the springs 11 press the bagmak 8 to the coil 9, since the force exerted by the tensioned wire on the bypass roller 10 is reduced. In this way, the pressure of the shoe against the surface of the bay increases, speeding up the stop of the driver and keeping the turns from falling out.

The device allows for increased productivity by preventing the possibility of entanglement of the wire.
