Abstract

PURPOSE:To improve work environment by stripping a wire, e.g. a magnet wire, by means of a cutter thereby obviating the necessity of chemicals. CONSTITUTION:A rotary base 2 disposed at the end of a drive shaft is pin 3-coupled with a plurality of arms 4 while a stripping cutters 11 are formed at the upper end of the arms 4 and a weights 5 are fixed, movably with respect to the arms 4, to the lower end thereof. Upon rotation of the drive shaft, each cutter 11 is rotated through centrifugal function of the weight 5 to strip a wire located in the center of the cutter 11.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for stripping wires such as magnet wires.

002]

2. Description of the Related Art Conventionally, the coating of this type of magnet wire has been removed by chemical removal using an organic solvent, which has the disadvantage of creating a poor working environment and being harmful to the human body due to the handling of harmful chemicals.

003

SUMMARY OF THE INVENTION The main object of the present invention is to improve the working environment by stripping the coating of wires such as magnet wires using a cutting blade without using chemicals.

004

[Means for solving the problem] A plurality of pin-connected arms are attached to a rotating base provided at the end of the drive shaft, a peeling cutting edge is formed at the upper end of the arm, and a weight is movable with respect to the arm at the lower end. What is claimed is: 1. A wire coating stripping device, which is attached to a wire coating stripping device, and coats the wires to be stripped installed at the center of each cutting blade by the centrifugal force of a weight caused by the rotation of a drive shaft.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIGS. 1 and 2 are a plan view and a side view showing the structure of a magnet wire peeling device. Reference numeral 1 indicates a motor, the rotational axis of the motor 1 is arranged vertically, a rotational base 2 is attached to the tip of the axis, and an arm 4 having a cutting edge 11 is connected to the rotational base 2 via a pin 3 rotatably supported. It can be attached at four locations on the circumference. A weight 5 is attached to the lower part of each arm 4 on the side opposite to the cutting edge, and if the side with the weight 5 below the cutting edge 11 with the pin 3 as the border is made heavier, the arm 4 will be vertical at the center of gravity. state. Also, the arm 4 can freely swing in the direction of the arrow 9 around the pin 3, and when the motor 1 is stopped, the arm 4 is in a vertical state, so each cutting edge 11 at the upper tip Since the wire is in an open state as shown by the two-dot chain line, it is easy to insert the wire and take it out after peeling.

The wire 7 is inserted into the center of the motor rotating shaft from above. As shown in FIG. 1, the cutting edge portion 11 is provided with a rake face 5 in the vertical direction of the contact point of the magnet wire 7, and a flank face 6 with a clearance angle 12 in the horizontal direction. When the flank face 6 is viewed from the side, as shown in Fig. 2, it is a circular arc with a radius R. This is to ensure that the contact state of the cutting edge remains the same even if the diameter of the magnet wire 7 varies. It is.

Now, when the rotating shaft of the motor 1 is rotated in the cutting direction indicated by the arrow 8, the cutting edge 11 closes due to the centrifugal force of the weight 5 and comes into contact with the magnet wire 7, and the coating begins to peel off. By moving in the direction of arrow 10, the required peeling dimension will be obtained.

In this case, the weight 5 is fixed to the arm 4 with a screw, and is movable in the direction of the arrow 13 so that it can be clamped at a required position.
Since the blade pressure on the magnet wire 7 can be adjusted, the necessary peeling thickness can be set by the centrifugal force of rotation and the contact pressure of the cutting blade.

0010

As explained above, according to the present invention, a plurality of arms connected by pins are attached to a rotating base provided at the end of a drive shaft, a peeling cutting edge is formed at the upper end of the arm, and a peeling cutting edge is formed at the lower end of the arm. A weight is movably attached to the arm, and as the drive shaft rotates, the centrifugal force of the weight acts to cover the wire to be peeled placed at the center of each cutting blade.

[0011] Since chemicals are not used as in the conventional method, the working environment is of course improved, and the peeling thickness can be changed by adjusting the centrifugal force. Furthermore, it is possible to adapt to the thickness of the wire, and it is easy to insert the wire and take it out after peeling.
