Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an electric wire sheathing burning-off device, and in particular, an electric wire sheathing burning-off device suitable for burning off the sheathing of continuous long electric wires at required intervals. Regarding.

[Prior art]

When connecting an electric wire coated with an insulating material to an electric device, an electric wire that is cut to a predetermined length in advance and has the coating removed from both ends may be used.

Further, when removing the sheathing from an electric wire, a special tool called a wire stripper is usually used, or a predetermined position of the sheathing is cut off, and then the sheathing is removed from the wire.

When burning off the sheathing of an electric wire, the sheathing of the electric wire is pressed against one or two heated exothermic wires (or held between them by a heater), and the electric wire is rotated to burn off the sheathing.

Such work is possible if the wire is cut to a predetermined length in advance.

However, if the wires are cut, it becomes extremely difficult to handle the wires when automating post-processes, and this becomes an impediment to automation.

For this reason, it is required to burn off the wire sheathing at predetermined intervals without cutting long wires, but the above-mentioned burn-off equipment requires rotating the wire, so the equipment is large. It has disadvantages such as being formalized and complicated.

[Purpose of invention]

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a small and simple mechanical wire sheathing cutting device.

[Summary of the idea]

In order to achieve the above object, in the present invention, a heated heating wire is brought into contact with an electric wire that is intermittently sent through a predetermined path, and the heating wire is rotated around the electric wire to cover the electric wire. It is characterized by being burnt off.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings.

The figure shows an embodiment of the wire sheathing cutting device according to the present invention. In the figure, 4 indicates a fixed block.

A hollow shaft 5 is rotatably supported by the fixed block 4, and constitutes a rotating member.

6 is a rotating block fixed to one end of the hollow shaft 5.

A block 2 is swingably supported by the rotating block 6 through a shaft 7, and constitutes a swinging member.

A heating wire 1 is supported on the block 2 by electrodes 3.sub.3a having different polarities.

A gear 8 is fixed to one end of the hollow shaft 5, and meshes with a gear 10 fixed to the rotating shaft of a motor 9 supported by a support member (not shown) to rotate the hollow shaft 5 intermittently one rotation at a time. constitute means.

11 and 11a are electrodes having different polarities, respectively, and slip rings 12 and 12 are formed on the outer periphery of the hollow shaft 5.
A current is applied to the heating wire 1 through a lead wire (not shown).

Reference numeral 14 denotes an actuator, which is supported above the stop position of the block 2 in the rotational direction by a support member (not shown), and has one end of the rod 15 engaged with the free end of the block 2, and is connected to one end of the block 2. A block 16 is fixed to the hook for pulling up, and constitutes a swinging means.

Note that a spring 17 is hung between the block 2 and the rotating block 6, and applies a swinging force to the block 2 in the direction in which the heating wire 1 contacts the electric wire 13.

In the above configuration, the electric wire 13 passing through the hollow shaft 5 and the rotating block 6 is transported by an appropriate feeding means (not shown).
It is fed intermittently at a predetermined pitch.

At this time, a current is applied to the heating wire 1, and the heating wire 1 is heated to a required temperature.

When the electric wire 13 stops, the actuator 14 operates,
The rod 15 is pushed out and the block 16 is lowered.

Then, the block 2 swings around the shaft 7, and the heating wire 1
is brought into contact with the electric wire 13.

Then, the covering of the electric wire 13 that came into contact with the heating wire 1 is burned.

In this state, when the motor 9 operates and rotates the hollow shaft 5 once, the heating wire 1 also rotates around the electric wire 13 once, so the electric wire 1
The coating of No. 3 can be burned off.

When the hollow shaft 5 rotates once, the actuator 14 operates to pull up the rod 15.

Then, the block 16 pulls up the free end of the block 72 and separates the heating wire 1 from the electric wire 13.

In this way, the covering of the electric wire 13 can be burned off.

In the above embodiment, two heating wires 1 are arranged, but it goes without saying that the number of heating wires 1 may be any number.

[Effect of idea]

As described above, according to the present invention, the heating wire that is in contact with the sheath of the wire is rotated around the wire.
This has the effect of providing a small and simple electric wire sheathing cutting device suitable for burning off the sheathing of long electric wires.
