Embodiment
Embodiment 1: a kind of thermal cutting cutter of cable sheath, comprises electrothermal steel cutter and heating power supply plug, U-shaped knife rest 1 and support wheel 11; Described electrothermal steel cutter are the C shape cutterhead 4 that inside is provided with insulating sleeve 17, the periphery of described insulating sleeve 17 is provided with the insulation board 8 of disjunctor, insulating sleeve 17 is inlaid in C shape cutterhead 4, the C shape cutterhead 4 of insulation board 8 both sides is respectively equipped with pin hole 7, and described pin hole 7 is suitable with heating power supply plug; Described electrothermal steel cutter are arranged in the inner left wall of U-shaped knife rest 1 by the left socle 6 that rotating shaft is housed, described support wheel 11 is arranged on the right side inwall of U-shaped knife rest 1 by the right support 14 that rotating shaft is housed, and the center of C shape cutterhead 4 and the center of support wheel 11 are on same horizontal line.Also comprise upper bolt 5, middle part bolt 2, upper arrester wires 9 and lower arrester wires 15; Described upper bolt 5 is arranged on the upper end of U-shaped knife rest 1 left side wall, described middle part bolt 2 is arranged on the middle part of U-shaped knife rest 1 left side wall, upper arrester wires 9 is connected between upper bolt 5 and U-shaped knife rest 1 right side wall, and lower arrester wires 15 is connected between middle part bolt 2 and U-shaped knife rest 1 right side wall.Also comprise leading screw 13 and handwheel 12, described leading screw 13 is threaded connection with the right side wall of U-shaped knife rest 1, and leading screw 13 left end is flexibly connected with right support 14, and leading screw 13 right-hand member is connected with handwheel 12.Also comprise handle 16, described handle 16 is arranged on the bottom of U-shaped knife rest 1.
C shape cutterhead 4 of the present invention can adopt high speed steel W18Cr4V or W9Cr4V to make, because high-speed steel has red hardness, below 560 degree, still can keep higher hardness.The insulating ceramics part that insulating sleeve 17 and insulation board 8 are integrated.Packing ring is installed in rotating shaft on left socle 6, and packing ring is positioned at the both sides of insulating sleeve 17, and gasket diameters is less than the diameter of edge distance sleeve 17, can solve Insulation Problems when C shape cutterhead 4 heats, also can prevent heat loss.Heat insulating mattress 3 is installed between left socle 6 and the left side wall of U-shaped knife rest 1, can prevents heat from conducting to U-shaped knife rest 1.Upper arrester wires 9 and lower arrester wires 15 can make of metal mesh shaped band, also can use nylon tape, and what width was greater than that 20mm can be stable stops cable.
