Description

Technical Field

[0001] The utility model relates to a cable laying auxiliary device, in particular to a power cable bending and pressing device. Background Art

[0002] Before assembling the power cable, it is often necessary to perform a bending process to form an elbow. In order to facilitate the bending operation, in recent years, people have designed relevant power cable bending and clamping devices to assist the cable bending operation. For example: Chinese patent CN214185022U discloses an electric wire bending and clamping device, in which a slider B is driven by a round rod to move along a slide groove B, and the restoring force of the spring B squeezes the roller at the front end backward to clamp the wire or steel strand, and the adjusting hand wheel is rotated to make the clamping block move to a suitable position along the slide groove A through the slider A and then fixed, and the rotating block is rotated back and forth along the support rod to make the pawl A and the pawl B drive the ratchet wheel to rotate, and the gear B is driven by the rotating rod to engage and transmit so that the gear A rotates synchronously, and the single groove wheel and the clamping block rotate synchronously so that the wire or steel strand is bent along the groove of the single groove wheel; Chinese patent CN209238905U discloses an electric wire bending and clamping device, in which the bending disk and the limit disk of the bending mechanism can adjust the position according to the thickness of the wire, and can bend wires of different thicknesses, and the clamping mechanism can clamp the bent wire. However, the bending structures of these wire bending processing equipment are all horizontally arranged on a flat plate. When the wire or steel strand is bent, the operator is often located on one side of the flat plate, and one end of the wire or steel strand will rotate horizontally, passing through the side where the operator is standing during the rotation, which can easily scratch the worker.
