SU139034A1 - A device for the electrical cutting of steel cables - Google Patents

Description

The known devices for electrically cutting steel cables containing current-carrying clamps for heating the cable in the cutting zone and the mechanism for breaking the cable in the heated zone do not automate the cutting process.

The proposed device automates the process of cutting the cable into pieces of a certain length.

The essence of the invention is that the device is equipped with a roller mechanism for feeding the cable into the heating zone and a limit switch that interacts with the end of the supplied cable and deactivating the feed mechanism for a given length of the fed cable, and the clamps are provided with an actuator clamping the cable after stopping the feeder and opening the clamps after breaking the heated cable.

FIG. 1 shows a schematic side view of the device; in fig. 2 - diagram of the pneumatic lift.

Inside the bed / placed welding transformer of low power, the secondary coil of which is connected to the electrodes of the clamping device 2.

The wire feed is carried out using mechanism 5; The cable is stretched by the mechanism 4, on which the cutting mechanism 5 with the movable electrical contact 6 is fixed, which determines the length of the cable being cut. On the left side of the device, a pneumatic lift 7 (Fig. 2) with a cable roller 8 mounted on it is installed. Cable through guide bushings with feed rollers. passed through the decompressed electrodes of the clamping device 2 along the guide plate of the shut-off mechanism 5 to the electrical contact 6.

No. 139034-2

When the contact is closed by the cable, the upper roller of the feeder rises (the supply of the cable stops). At the same time, the electrodes of the clamping device clamp the cable.

Through the cable, clamped between the electrodes, a welding current is passed through, heating it to red heat. - The curing mechanism, moving the movable plate to the right, reduces the diameter of the cable, seals the heated wire. The welding current is passed through again - the ends are melted, the cable is cut. The cut-off mechanism releases the cut cable from the rail guide. The cylinders return the mechanisms to their original position — the cycle repeats:

Subject invention

A device for electrically cutting steel cables, comprising current clamps for heating the cable in the cutting area and a mechanism for breaking the cable in the heated area, characterized in that, in order to automate the cutting process, it is provided with a roller mechanism for feeding the cable into the cable. the heating zone and.-limit switch that interacts with the end of the supplied cable and switching off the feed mechanism at a given length of the fed cable, and the clamps are provided with a drive clamping the cable after stopping the feed mechanism and opening the clamps after the heated cable breaks.
