SU454626A1 - Insulation firing machine, twisting the wires and cutting the installation wires - Google Patents

Description

Machines are known for firing insulation and cutting of flashing stranded wires of a given length, a wire fed with a roller feed by a mechanism, and the firing of the insulation is performed by two pairs of plate firing elements applied to the wire from two sides at the time of firing.

However, in these machines, there are no devices for twisting the strands of the burned-out wire end, the cutting knives are short-lived.

The proposed machine comprises a roller feeder, lamellar firing elements, a twisting mechanism, a counting mechanism, a cutting device and a command device. The twisting mechanism of the veins is made in the form of two clamps installed rotatably in opposite directions with respect to two stationary burning elements, and the cutting device is installed outside the insulation firing zone.

The drawing schematically shows the proposed machine.

The wire feed mechanism consists of a driving roller 1 rotating from a carrier 2 of a bevel gear differential with a driving sun wheel 3, and a pressure roller 4. The counting mechanism contains a pair of counting rollers 5, one of which has a sensor 6 disk that sends a pulse.

sy in an electronic counting command device with electromagnets 7-10. The twisting mechanism of veins consists of two clips 11 installed rotatably in opposite directions, each of which contains two pairs of spring-loaded springs 12 clamping dies 13. In each of these dies, pins 14 are pressed in, which slide in gear shaped slots 15. x 16 having the possibility of rotation with respect to smallpox clamps 11 and interacting teeth with clamps 17, which are connected through cams 18 with firing plates 19 by means of shaft 20. The cut-off device is made in the form of disk n ments 21 and 22 with holes for the wires. The disk cutter 22 is movable and rotates from the electromagnet 10.

The degree of twisting of the burned area is regulated by the electromagnet 9. The machine operates as follows. Moving in the process of feeding the wire rotates the counting rollers 5, while the disk 6

sends pulses to an electronic-counting command device. When the wire is drawn and its length is measured, the firing plates 19 are retracted from the wire. Cams 18 clamps 17 are inserted into the gear teeth 16, and clamping combs 13 under the influence of shaped grooves 15 through pins 14 are retracted from the wire, springs 12 are compressed.

Upon reaching a predetermined length, the command device turns on the electromagnets 7 and 8. The electromagnet 7 stops the carrier 2 of the bevel gear differential, on which the driving roller 1 is fixed and retracts the pressure roller 4, the sun wheel 3 is released and the rotation is transmitted to the clips 11 of the firing and twisting unit. The electromagnet 8 brings the firing plates 19 to the I / V and leads the clips 17 out of engagement with the gears 16, and the clamping dies 13 by the force of the springs 12 clamp the wire.

The clamps 11, rotating in opposite directions, rotate the wire relative to the firing elements, thereby ringing off the insulation and twisting the cores of the wire section between the firing elements.

At the end of the burning and twisting, the command device turns off the electromagnets 7 and 8, and the actuators of the machine return to their original position. The clamps 11 cease to rotate and unfold, freeing the wire, the firing plates 19 move away from the wire, the pressure roller 4 presses the wire to the drive roller 1, the wire starts to flow and its length begins.

Cutting the wire occurs in the process of its filing. As soon as the irovod is supplied to a length equal to the distance from the leading edges of the knives 21 and 22 to the middle distance between the clamps II (this distance is constant for the automaton), the command device turns on the electromagnet 10 and it turns the movable knife by means of the ratchet 22
