A cable slicer

Abstract

The invention discloses a cable slicer, which comprises a motor, a transmission device, a chuck, a cutter device, a transverse mechanism and a longitudinal mechanism. The motor is arranged on a base, and the output end of the motor is connected to the chuck through a transmission device. , and drives the chuck to rotate, the front end of the chuck is provided with a clamping mechanism; the cutter device is correspondingly arranged in front of the chuck, and the cutter device includes a knife holder and a circular blade arranged at the rear end of the knife holder , the cutting edge of the blade is perpendicular to the rotation axis of the chuck and corresponds to the clamping mechanism; the transverse mechanism is arranged at the bottom end of the knife holder, and the transverse mechanism drives the blade to move laterally relative to the chuck ; The longitudinal mechanism is arranged at the front end of the tool holder, and the longitudinal mechanism drives the blade to move longitudinally relative to the chuck; the motor is controlled and operated by an electric control device. The invention improves the cutting efficiency and cutting precision of the cable insulation sheet, and effectively meets the needs of large-scale detection.

Description

Technical field [0001] The invention relates to the technical field of cable detection equipment, in particular to a cable slicing machine. Background technique [0002] According to GB / T 2951.11-2008 "General Test Methods for Insulating and Sheathing Materials of Cables and Optical Cables Part 11: General Test Methods-Thickness and Dimensions Measurements-Mechanical Performance Tests", the preparation requirements for measurement specimens for thickness and dimensions are as follows: Remove all protective layers from the insulation and extract the conductors and isolation layers. Be careful to avoid damaging the insulation. If the inner and outer semi-conductive layers adhere to the insulation, you do not need to remove them. Each test piece is composed of an insulating sheet, and a suitable tool (a sharp blade such as a razor blade, etc.) is used to cut the sheet along a plane perpendicular to the axis of the conductor. [0003] For medium voltage (35kV and below) cross-linked ...

AI Technical Summary

Problems solved by technology

[0003] For medium voltage (35kV and below) cross-linked cable insulation thickness measurement, the industry generally adopts the method of manually cutting the insulated wire core with a blade to obtain the insulation test piece. Using this method to cut the cable has a high technical requirement for the operator's proficiency , the yield is difficult to control, the efficiency is extremely low, and the accident rate is high. In addition, the cut insulating sheet is thick (generally 2mm), and it is easy to damage the insulating sheet, which affects the test data such as insulation thickness (the thinner the test piece, the thickness The more uniform, the more accurate the test result), especially not conducive to the inspection of a large number of testing institutions
