Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable processing technology, and in particular to a cable cutting device. Background Technology
[0002] Flame-retardant cable cutting devices face technical challenges in terms of blade wear and cable positioning. Traditional blades are prone to rapid wear, dulling, and even chipping due to the corrosiveness, high hardness, and multi-layered composite structure of the outer sheath materials of flame-retardant cables (such as halogenated flame retardants, mica tape, or halogen-free high-hardness polymers). This leads to decreased cutting efficiency, increased burrs on the cut, and frequent blade replacements, increasing maintenance costs. Traditional mechanical clamps are difficult to hold stably and are prone to slippage during cutting. Positioning methods that rely on manual calibration are not accurate enough, with errors often exceeding ±1mm, resulting in uneven cuts, insulation delamination, or conductor damage, affecting electrical performance and installation reliability. Therefore, a novel cable cutting device is provided to solve the above problems. Utility Model Content
