An annular groove for protruding and fixing a pair of rotating bodies by vertically arranging the protruding one end of the upper shaft and one end of the lower shaft in parallel with each other, and fitting the electric wire to the outer peripheral portion of the lower rotating body. And an annular blade corresponding to the groove is formed on the outer peripheral portion of the upper rotating body, a motor is mounted on the base located on the other side of the supporting column, and the lower rotating body is mounted on the motor. A structure for connecting the other end of the rotating body to an adjusting mechanism for vertically adjusting the rotating body of the upper part, providing a cover surrounding each rotating body, and forming a window for supplying and discharging electric wires to the cover. It is the one.

(Operation) Since the present invention has the above-mentioned configuration, when the cover is removed, each rotating body is opened to the outside, and these can be easily exchanged with other ones. Further, when the electric wire or the covering of the peeled electric wire is wrapped around the rotating body, the work of removing the covering can be performed from the one side surface side of the opened rotating body.

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

In the drawings, FIG. 1 is a partial sectional side view showing an embodiment of the present invention, FIG. 2 is a side sectional view of a main part of a supporting shaft according to a second embodiment, and FIG. 3 is a third embodiment of a supporting shaft. FIG. 3 is a side sectional view showing a main part of FIG.

In FIG. 1, reference numeral 1 is a base. On the upper surface of the base 1, a column 2 is erected and fixed on the left side thereof, and a motor 3 (gear motor) having a reduction gear 3a installed therein is fixed and fixed on the right side thereof. To do.

An upper shaft 4 and a lower shaft 5 are arranged at the upper and lower parts of the column 2 so as to extend in the left-right direction, and are rotatably supported by an upper bearing 6 and a lower bearing 7.

The upper shaft 4 and the lower shaft 5 are projected to the left from the support column 2, and the upper rotating body 8 and the lower rotating body 9 are fixedly supported by these protruding portions, respectively.

The upper rotating body 8 is formed in a disk shape, and the outer peripheral portion thereof is ground into an acute angle mountain shape to form an annular blade 8a.
The lower rotating body 9 is formed in a cylindrical shape and has the blade 8a.
The outer peripheral portion corresponding to is ground into a valley shape to form an annular groove 9a.

Then, the upper rotating body 8 is adjusted to the lower rotating body 9 by the adjusting mechanism 10.
The lower rotary body 9 is directly connected to the above-mentioned motor 3 by means of a shaft coupling 15.

The adjusting mechanism 10 has a vertically elongated long hole 2a formed in the upper portion of the support column 2, and a rectangular slide case 11 having an upper bell ring 6 fitted therein is slidably fitted in the elongated hole 2a. To do. Further, a screw rod 12 is screwed onto the upper end of the column 2, the upper end of the slide case 11 is rotatably connected to the lower end of the screw rod 12, and a handle 13 is fixed to the upper end of the screw rod 12.

In addition, 14 is a threaded rod 12 between the handle 13 and the pillar 2.
It is a lock handle screwed to.

Reference numeral 16 is a cover that surrounds the upper and lower rotating bodies 8 and 9, and a window 16a for supplying and discharging a processing electric wire 17 is formed on the facing surface side of each rotating body 8 and 9.

Next, the manner of use of the above embodiment will be described.

First, by operating the adjusting mechanism 10, the screw rod 12 is rotated in a predetermined direction to move the upper rotary body 8 in the vertical direction, set the gap between the blade 8a and the recess 9a to a predetermined value, and tighten the lock handle 14. Then, the rotation of the screw rod 12 is locked.

Next, the motor 3 is started, and the electric wire 17 for processing is connected to the window 16a.
To the biting side of the lower rotating body 9.

Then, the electric wire 17 is held between the blade 8a of the upper and lower rotating bodies 8 and 9 and the recess 9a.

In this case, since the cross-sectional shape of the recess 9a is V-shaped, the frictional force with the electric wire 17 due to the clamping force is larger than that of the blade 8a.

Therefore, the torque of the lower rotating body 9 is transmitted to the upper rotating body 8 through the electric wire 17, and the blade 8a is rotated in synchronization with the rotation of the recess 9a, whereby the blade 8a covers the electric wire 17. 17
By cutting a in the longitudinal direction, the coating 17a can be peeled from the core wire 17b.

Then, when the blade 8a and the recess 9a are worn, or when it is desired to replace the blade with another one of a different type, the cover 16 is removed, and the rotary members attached to the left ends of the upper and lower shafts 4 and 5.
Remove the stoppers (code omitted) of 8,9. Then, each rotating body 8,9

Replace with 8, 9 or other type of different type.

Further, when the electric wire 17 or the covering 17a of the peeled electric wire is wound around the rotating bodies 8 and 9, the cover 16 is removed to expose the rotating bodies 8 and 9, and the upper left portion is wound using the open left space. The electric wire 17 or the coating 17a is removed.

The upper and lower rotating bodies 8 and 9 according to the present invention may have the structures shown in FIGS. 2 and 3.

That is, in FIG. 2, the upper and lower rotating bodies 20, 20 are both formed in the same shape, and two kinds of V-shaped and annular recesses 20a, 20b having different widths and depths in the axial direction are formed. To form
V-shaped and annular blades 20a and 20d are formed to project outward in the radial direction from the axial center of the bottom surfaces of the recesses 20a and 20b.

The one shown in Fig. 2 has the upper and lower recesses 20a (20b) and 20a (20
The wire 17 is clamped by b) and the upper and lower blades 20c (20d) and 20c
By (20d), the covering 17a of the electric wire 17 is axially cut above and below it.

Further, FIG. 3 shows the upper rotary body 21 and the lower rotary body.
The upper rotor 21 has a large-diameter and stepped blade 21a formed in the axial center of its outer periphery, and the lower rotor 22 has a small diameter in the axial center of its outer periphery. In addition, a stepped recess 22a is formed.

In the case of FIG. 3 described above, when the electric wire 17 is sandwiched between the blade 21a and the recess 22a, the left and right edges of the blade 21a and the recess 22a cut the left and right side portions of the covering 17a.

(Effects of the Invention) As is apparent from the above description, the present invention allows easy attachment and detachment of the rotating body, and by selecting and attaching a predetermined rotating body, it is possible to peel off coatings of various types of electric wires.
