Description

[Detailed description of the invention] This invention relates to a wire sheathing stripping device for treating the ends of wires such as wiring and cables of electrical equipment and electronic equipment, and is particularly applicable to multi-core wires with large variations in the outer diameter dimension and internal component dimensions. The present invention relates to a wire sheath stripping device suitable for stripping the sheath of cables or coaxial cables.

Conventionally, as this type of wire sheath stripping device, there are a so-called wire stripper having a sheath cutting blade and a so-called thermal stripper that heats and melts the sheath.

Wire strippers have the disadvantage that due to variations in the thickness of the wire sheathing or the dimensions of the internal components, the sheath may be cut incompletely or the internal components may be damaged.

In addition, since the thermal stripper uses a thermal heater to burn the coating and cut it, it does not have the disadvantages of the wire stripper described above, but since the thermal heater is used instead of a peeling piece to peel off the coating,
It shortens the life of the heater and is not suitable for wires with coatings that are difficult to peel.

In some cases, a separate peeling piece is inserted after the coating is heated and softened using a heater, but if there are variations in the dimensions of the coating or internal components, the coating may sag.

The purpose of this invention is to provide a wire sheath stripping device that eliminates the above-mentioned conventional drawbacks, absorbs variations in the thickness of the sheath and the dimensions of internal components, and is capable of stripping the sheath without damaging the internal components. It's about doing.

The idea is to burn the insulation of the wire with a resistance heater wire and completely melt the insulation, then insert a peeling piece that matches the dimensions of the internal components into the burned area and move this peeling piece. This method is characterized by complete coating removal without damaging internal components.

Next, this invention will be explained in detail with reference to illustrated embodiments.

FIG. 1 is an embodiment of this invention, and FIGS. 2 and 3 are explanatory diagrams of its operation.

In Fig. 1, the wire coating stripping device according to this invention is
The target electric wire 1 is guided by a wire guide 2, and includes a resistance heating heater unit 3 consisting of a pair of left and right resistance heating heater wires 7 and 8, and a peeling piece consisting of a pair of peeling pieces 5 and 6 at the bottom of -L. Drive cylinders 9 and 15 inserted between units 4 and plate cams 10 and 16 connected thereto.
A pair of left and right resistance heating heater wires 7,
8 moves left and right, and a pair of upper and lower peeling pieces 5 and 6 move up and down.

FIG. 2 is an explanatory diagram of the operation seen from the cross-sectional direction of the target electric wire 1, and FIG. 3 is an explanatory diagram of the operation viewed from the longitudinal direction of the target electric wire 1.

In FIGS. 2 and 3, the target electric wire 1 is positioned so that the resistance heating heater wires 7, 8 and the peeling pieces 5, 6 are located at a distance l from the wire end face 13, as shown in FIG. 2a.
, Fig. 3 a), First, a pair of left and right resistance heater wires 7,
8 in the X direction to apply a burn over the circumference of the coating 11 (Fig. 2b), then move the pair of upper and lower peeling pieces 5 and 6 up and down, that is, in the Y direction, to remove the circumference of the burn area. The sheathing 11 is separated from the internal components 12 by biting in the flanges 14 of the half-moon-shaped peeling pieces 5 and 6 at the top (FIG. 2C) and pulling out the target electric wire 1 in the Z direction. The coating can be peeled off (Figure 3b).

Note that at this time, the peeling pieces 5 and 6 may be moved.

As explained above, according to this invention, the following effects can be obtained.

1. Since the coating is burnt with a resistance heater wire, a peeling piece is placed in the burned area, and the peeling piece or wire is moved, variations in the outer diameter of the coating and the dimensions of internal components can be avoided. It can be absorbed and the coating can be removed without damaging internal components.

26 Since the coating is peeled off at the brim of the peeling piece,
The lifespan of the heater can be significantly extended.

3. By combining the resistance heater wire and the peeling piece, it is possible to reliably and completely peel off the coating, and it is possible to automate the process from coating peeling to processing of internal components.
