[Problems to be solved by the device]

 However, in the wire strip device described above, when the V-shaped notches 9a and 10a of the strip blades 9 and 10 form the long strip Wc of the wire W as shown in FIG. The frictional resistance between the long coating Wa and the long coating Wa is large, and it is difficult to form the meandering state of the long coating Wa and smoothly separate the coating.

In particular, when the long strip Wc of the electric wire W has a length of about 100 mm or more, not only is it difficult to form a stable long strip Wc, but also the quality of the long strip Wc is impaired and both strip blades are With the uncut portions of the coating portion Wa at the corners (four corners) of the V-shaped cut portions 9a and 10a of 9, 10, the peeling of the coated portion Wa becomes difficult, and the uncut portions of the long strip Wc are broken. It is difficult to form a long strip with good quality and a good shape.

In order to solve the above-mentioned problems, the present invention eliminates the meandering state of the long coating due to the friction resistance between the core wire of the electric wire and the long coating, and smoothly peels the long coating. An object of the present invention is to provide a long-strip device for electric wires designed to be improved.

[0009]

Means for Solving the Problems The present invention relates to an electric wire stripping apparatus including a pair of stripping blades provided in a frame of an electric wire processing machine so as to face each other and make a cut in a coating of an electric wire. Each clamp member is provided on the side surface of the so as to grip the wire coating.

[0010]

[Action]

 According to the present invention, both strip blades and each clamp member face each other to grip the covered portion of the electric wire and cut at the same time so as not to damage the core wire, and at the same time, cut the electric wire to a predetermined length with each cutting blade. At the same time, by moving the electric wire in the axial direction, the covering portion of the electric wire W is peeled off to form a long strip, and the covering portion is easily peeled off to improve the quality.

【Example】

 Hereinafter, the present invention will be described with reference to illustrated embodiments.

The present invention will be described by giving the same reference numerals to the same constituent members as those of the above-described specific example.

1, 2, and 4, reference numeral 1 is a machine frame of an electric wire processing machine, and a pair of bearings 2 is attached to both sides of the machine frame 1, and both bearings are provided. A pair of guide rails 3 (only one is shown in the figure) 3 are arranged in parallel with each other. A pair of cutter holding members 4 and 5 are slidably mounted on the guide rails 3 so as to face each other, and the lower portions 4a and 5a of the cutter holding members 4 and 5 are respectively attached to the lower portions 4a and 5a. The connecting rods 6a and 6b are connected with each pin. Further, the lower ends of the connecting rods 6a and 6b are connected to an output shaft 7a of a cylinder device 7 such as an air cylinder device by a connecting pin 8 so that the cutter holding members 4 and 5 can be connected to each other. A pair of strip blades 9 and 10 and respective cutting blades (not shown) face each other at both upper end portions 4b and 5b and are fixed by respective mounting screws 11. Furthermore, V-shaped notches 9a and 10a are formed in the strip blades 9 and 10 to form a rectangular notch in the covering portion Wa of the electric wire W so as not to damage the core wire Wb (see FIG. 1). Further, a pair of relatively long upper and lower clamp members 20 and 21 are fixed to the side surfaces of the strip blades 9 and 10 by fixing screws 22 so as to grip the coating Wa of the wire W. The gripping surfaces of the clamp members 20 and 21 are formed with saw-toothed gripping portions 20a and 21a so as to smoothly grip the long strip Wc having a comparatively long coating Wa.

On the other hand, a stopper 5c is vertically provided on a lower portion 5a of the one cutter holding member 5, and the stopper 5c is an adjusting screw rod 12 which is horizontally attached to the machine frame 1 to both the cutter holding members. The movement distances of 4 and 5 are regulated (see FIG. 4).

The operation of the present invention will be described below.

Therefore, when the measuring wire W gripped by the wire gripping device 13 in the wire processing machine is transferred to the strip position and stopped, the both strip blades 9 and 10 that are open are moved to the cylinder device. By driving 7, the output shaft 7a slides the cutter holding members 4, 5 inwardly through the connecting rods 6a, 6b, so that the output shaft 7a is integrated with the cutter holding members 4, 5. The strip blades 9 and 10 and the gripping portions 20a and 21a of the clamp members 20 and 21 and the respective cutting blades (not shown) face each other to grip the covering portion Wa of the electric wire W and cut at the same time so as not to damage the core wire Wb. At the same time when the electric wire W is cut into a predetermined length with each cutting blade (not shown) while the electric wire W is axially formed, the covering portion Wa of the electric wire W is peeled off. Then, the long strip Wc is formed.

Next, in another embodiment of the present invention shown in FIG. 3, a plurality of (three) clamp members 20, 21, and 23 are provided on the side surfaces of the strip blades 9 and 10 to cover the electric wire W with Wa. The holding members 20a, 21a, and 23a are provided so as to be gripped, and saw blade-shaped gripping portions 20a, 21a, and 23a are formed on the gripping surfaces of the clamp members 20, 21, and 23 so as to smoothly grip the long strip Wc.
