Molding device for cable fan-shaped conductor

Abstract

Disclosed is a molding device for a cable fan-shaped conductor, which is capable of guaranteeing that the fan-shaped conductor is rolled and pressed to be regular. The molding device comprises a rack, an upper press roller and a lower press roller which are arranged in the rack, capable of being adjusted in the up-down direction and provided with molding grooves, and an upper gate-shaped press roller rack and a lower gate-shape press roller rack which are coaxially disposed outside the upper press roller and the lower press roller. The upper press roller, the lower press roller, the upper gate-shaped press roller rack and the lower gate-shaped press rack are positioned on the rack through shafts, sliding sleeves are correspondingly arranged on at least one sides of the upper gate-shaped press roller rack and the lower gate-shaped press rack, the sliding sleeves are sleeved on the shafts, and rotary nuts are additionally arranged outside the sliding sleeves. The upper press roller and the lower press roller can be respectively moved not only in the up-down direction but also in the left-right direction, and the upper press roller and the lower press roller can operate in a centering mode, so that the service life of the press rollers is prolonged.

Description

technical field [0001] The invention is an improvement on a fan-shaped conductor forming device for power cables, and in particular relates to a cable fan-shaped conductor forming device capable of ensuring the regularity of rolled fan-shaped conductors. Background technique [0002] Large-capacity wires and cables, for example, the conductor cross-section is 25mm 2 above to 400mm 2 , In order to effectively reduce the outer diameter of the cable, reduce the amount of filling material and sheath material, reduce costs, and facilitate cable laying, the single conductor for stranded wire usually adopts 120° and 90° fan-shaped conductor structures. Existing fan-shaped conductor forming device ( figure 1 ), the basic structure is: in the frame 1, there are pressure rollers 5 with forming grooves symmetrically arranged up and down, and there is a door-type pressure roller frame 4 on the outside of the pressure rollers to adjust the pressure rollers to move up and down. It is p...

AI Technical Summary

Problems solved by technology

However, objectively, there is a certain gap between the pressure roller and the pressure roller frame, and it is actually difficult to adjust the lower two pressure rollers to the same vertical line during assembly and installation.

The pressure roller is fixed on the shaft, and the shaft is fixedly connected with the frame, so the upper and lower pressure rollers cannot be adjusted left and right.

If the upper and lower pressure rollers are not installed on the same vertical line, the shape of the fan-shaped conductors rolled out will be deformed, and flashes will be generated. Misaligned rolling will easily damage the pressure rollers, and the actual service life is not long.
