Straightening equipment for outer-coated polyethylene cables

Abstract

The invention discloses straightening equipment for a polyethylene coated cable. The equipment structurally comprises a heating roller device, an upper movable table, a transverse guide roller device,a cable end clamping device, a cable winding device, a longitudinal guide roller device, a lower movable table, the cable and a bidirectional piston cylinder. The upper movable table is arranged overthe lower movable table in parallel, and the upper movable table and the lower movable table are connected together through the bidirectional piston cylinder. Compared with the prior art, the equipment has the beneficial effects that the equipment can adapt to polyethylene coated cables with different apertures, and the end of the cable can be clamped before cable straightening so that the cablecan straightly stretch into the center of a straightening operation chamber, the problem that the cable deviates left or right is avoided, the cable can penetrate through the straightening operation chamber quickly, cable winding of a winding wheel is facilitated, and the cable straightening operation of the straightening equipment is facilitated.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a straightening device for outer-coated polyethylene cables. Background technique [0002] Most cables need to be bent during wiring. Since the cable has a built-in copper core, it is difficult to return to the straight state after bending, which not only affects the appearance, but also affects the continued use of the cable, so the cable needs to be straightened . [0003] Existing cables have outsourcing insulating protective sheaths, some of which are made of different materials such as polyvinyl chloride, polyethylene, rubber, etc. As far as cables covered with polyethylene are concerned, because polyethylene has poor creep resistance, it is not suitable for bending When the outer-coated polyethylene cable is straightened, the cable cannot be straightly stretched into the center of the straightening operation room, and it is easy to deviate to the left or right, and it is di...

[0003] Existing cables have outsourcing insulating protective sheaths, some of which are made of different materials such as polyvinyl chloride, polyethylene, rubber, etc. As far as cables covered with polyethylene are concerned, because polyethylene has poor creep resistance, it is not suitable for bending When the outer-coated polyethylene cable is straightened, the cable cannot be straightly stretched into the center of the straightening operation room, and it is easy to deviate to the left or right, and it is difficult to pass through the straightening operation room for the reel to be rewound. Therefore, a A straightening device capable of solving the above-mentioned problems
