Abstract

The invention discloses a straightening plier for a secondary cable core. The straightening plier comprises first and second plier bodies and a mold core part. The middle parts of the first and second plier bodies are connected via a rotating shaft. The mold core part comprises an upper mold core and a lower mold core. The upper mold core is arranged at the front end of the first plier body. The lower mold core is arranged at the front end of the second plier body. The upper and lower mold cores are provided with grooves which are matched with each other. The straightening plier is small in size, convenient to carry, simple in operation, convenient to use and great in straightening effect so that manual work is substituted. Meanwhile, the mold core can be replaced according to different specifications of the cable core so that application range is wide. The straightening plier has a position-limiting function so that strength can be well controlled, and loss of the cable core in the compressing process can be prevented.

Description

technical field [0001] The invention relates to the technical field of wire and cable equipment, in particular to a straightening pliers for secondary cable cores. Background technique [0002] Secondary cables refer to cables used for control, signal transmission and feedback, such as motor operating column control cables, metering, protection, and electrical communication cables, all of which are secondary cables. [0003] During the laying of power lines, the requirements for secondary cables are relatively high. The secondary cable leaves the factory in the form of a disc, and the straightness of the secondary cable must be ensured when connecting the lines. Therefore, curved and bent secondary cables are not acceptable. At present, when carrying out the straightening of the secondary cable, it is often done manually. Fix an angle iron or other metal parts with through holes on the ground, bind one end of several secondary cables to be straightened in the through hole...
