Annular cutting device and cutting system

Abstract

The invention discloses an annular cutting device and a cutting system. A cable penetrates into an operation port; the position of a pressing assembly on a support frame is adjusted, so that the pressing assembly is close to a pressure-bearing member; and the pressing end of the pressing assembly is matched with the pressure-bearing end of the pressure-bearing member to clamp the cable, so that the cable is stabilized on the support frame without holding by an operator to fix, thus, manpower output is greatly reduced, and the cable sampling process becomes time-saving and labor-saving. Due tothe fact that a cutter head of a cutting knife stretches into an operation port, when the cable is clamped, the cutter head of the cutting knife acts on the surface of the cable, and at the moment, the annular cutting operation of the cable can be completed only by rotating the cable or rotating the support frame, therefore, the cable sampling process is greatly facilitated, the operator can quickly obtain a test sample of the cable, and accordingly, cable testing efficiency is favorably improved.

Description

technical field [0001] The invention relates to the technical field of cutting, in particular to a circumcision device and a cutting system. Background technique [0002] According to relevant national standards and industry standards, cables need to be sampled for testing projects. The cable mainly includes a metal part and a non-metal part, and the non-metal part includes a sheath, an isolation sleeve, an inner liner and an insulating layer; among them, the non-metal part is usually made of polyvinyl chloride or polyethylene with a relatively dense molecular structure. In the construction and testing of power cables, it is necessary to cut and sample the sheath, isolation sleeve, inner lining and insulating layer. The cutting methods are divided into various sampling methods such as linear cutting along the longitudinal direction of the cable and circular cutting of the cross section. The tools used are complex and the workload is enormous. [0003] At present, the cable...

Problems solved by technology

In the construction and testing of power cables, it is necessary to cut and sample the sheath, isolation sleeve, inner lining and insulating layer. The cutting methods are divided into various sampling methods such as linear cutting along the longitudinal direction of the cable and circular cutting of the cross section. The tools used are complex and the workload is huge

[0003] At present, the cable sampling method usually adopts a manual method. The general tool is a utility knife, and the cable is circumcised with a utility knife. This process is time-consuming and laborious, and requires a certain degree of proficiency of the operator. In this way, the efficiency of cable testing is seriously affected.
