Description

Mechanical calliper

Technical Field

The utility model relates to the technical field of CCV production cable measuring tools, in particular to a mechanical calliper.

Background

The suspension chain type continuous vulcanization process refers to a process that vulcanization pipes are arranged in a suspension chain type from top to bottom, and cross-linking is completed in the pipes, and is abbreviated as CCV, and because an insulating layer cannot be completely solidified before cross-linking reaction, and because of the self weight of a cable, the problem of eccentric insulation can be effectively avoided through the process.

However, CCV is used as a production process of early crosslinked cables, which solves the problem of eccentricity caused by insulation, but because the insulation layer is unevenly stressed, the problem of inconsistent outer diameter of the cable is easily caused before the insulation layer is fully cured, and therefore in the production of rubber cables and crosslinked cables, the diameter of the cable in a pipeline is checked by a mechanical contact measurement mode and a corresponding current or voltage signal is output to an electric control part of a production line.
