Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a wire rod coating stripping tool for stripping the coating of wire rods such as optical cables.

(Prior Art) When stripping the coating of a wire rod, generally, make a cut in the circumferential direction of the wire rod with a cutter such as a cutter knife, and make a linear cut in one longitudinal direction from this cut to peel the coating. I was going. However, with this method, the wire rod itself may be damaged or the operator himself may be injured unless he is an expert.

Therefore, a tool shown in FIG. 7 has been used as a portable tool. In the figure, 100 is a turret, and this turret 1
A cylindrical portion 101 is provided at the center of 00. A sleeve ring 102 is attached to the inside of this cylindrical portion, and this sleeve ring 102 is rotatably attached to the cylindrical portion 101 by a ball catch, and its rotation is quick-stopped every 90 degrees. A blade shaft 103 is screwed into the sleeve ring 102, and a chuck 103 is attached to the tip end side of the blade shaft 103.
a is formed, and this chuck 103a has a double-edged blade 1
04 is attached.

A bar 100a is provided on the lower side of the central portion of the tool rest 100, and the other end side of the bar 100a is bent upward.
It is in contact with a cylindrical portion 105a provided on a pressing base 105 slidably attached to 100a.

The abutment of the cylindrical portion 105a of the bar 100a allows the pressing table 105 to be held substantially vertically to the bar 100a. The pushing table 105 is formed on a substantially L-shaped block stand, and an insertion hole 105b through which the bar 100a is inserted is provided in the lower portion, and the pushing table 105 and the bar 100a are provided below the insertion hole 105b.
A tightening screw 106 for fixing to is provided. This tightening screw 106
The pushing table 105 can be slid on the bar 100a in the left and right direction by loosening, and the pushing table 105 is fixed at any position by tightening the tightening screw 106, and is substantially perpendicular to the bar 100a. Fixed in the direction. In the vertical portion of the pushing table 105, the cylindrical portion 105a is located on the center line of the blade 104 of the blade holder 100.
Is provided, and the coil spring 107 is mounted in the cylindrical portion.

A V-board 109 is attached to such a pushing table 105 via a locking pin 108.
Is rotatably attached. The V platform 109 is mounted so as to straddle the lower part of the pushing platform 105, and the V side 109a is aligned with the center of the blade 104 on the side corresponding to the tool platform 100.
Is formed, and the coil spring 107 is abutted on the back side of the V-shaped surface 109a.
It is attached to the 100 side in a slightly squeaky manner.

The wire rod peeling tool with the above-mentioned configuration is
The blade 104 of 103 is projected to a predetermined height (corresponding to the coating thickness) in the tool rest 100, and the cutting direction of the blade 104 is aligned with the sleeve ring 102 in the circumferential direction of the wire. Next, the tightening screw 106 is loosened, the wire is attached to the V-shaped surface 109a, the pushing table 105 is brought close to the tool rest 100, and the pushing stand 105 is fixed when the surface of the wire comes into contact with the tool rest 100. By rotating the tool in the circumferential direction of the wire rod in this state, a cut having a predetermined depth is made in the covered portion of the wire rod. Next, the blade 104 is rotated by the sleeve ring 102 in the direction perpendicular to the circumferential direction, and by moving the tool in the longitudinal direction of the wire rod,
Even if the wire rod is installed, the coating can be peeled off.

(Problems to be solved by the invention) In the above-described conventional wire rod peeling tool, the center of the blade is attached toward the center of the wire, and the blade uses double-edged blades. Since the configuration is a V unit, when the tool is rotated in the circumferential direction of the wire rod, the outer peripheral surface of the wire rod becomes V-shaped.
Rubbing with the surface causes the blade not to cut the same circumferential surface on the wire-covered surface, and the cut circumference becomes spiral and peels off the end surface of the coating to form irregularities, especially the blade. If the tool is rotated at a right angle from the circumferential cutting direction, it will be dug on both sides of the cut due to the double-edged blade, and not only the product will not be finished well, but the optical fiber cable may suffer damage accidents. there were.

In addition, in the conventional wire rod peeling tool, the wire rod is clamped between the tool rest and the pressing pad and then fixed with the tightening screw, so the tool must be handled with both hands to peel off the coating of the erected wire rod, etc. It also had the drawback of being difficult and difficult.

The present invention has been made in view of the above circumstances, and an object thereof is to cut the coating of the wire rod with one line in the circumferential direction and to adjust it according to the thickness of the wire rod or the like. In addition, the present invention is intended to provide a wire rod coating peeling tool that can be easily clamped.

(Means for Solving the Problem) In order to achieve the above object, the wire rod coating peeling tool of the present invention has a wire rod sandwiched between a tool rest and a pressing base provided on a gantry, and the wire rod in the circumferential direction. In the wire rod peeling tool for rotating the gantry to make a cut with a constant depth in the circumferential direction of the wire rod and peeling the wire rod coating by making a notch on one side in the length direction of the wire rod from this cut position, (1) is a wire rod coating peeling tool which is provided on a tool rest and fixes the ridge of the tool at the center of the tool axis to which the tool is attached. A wire rod peeling tool comprising two rollers arranged in parallel with each other and a roller support metal fitting for holding the inter-center distance of the rollers so as to be equidistant from the center of the blade shaft. ,
In (3), the pressing base is fixed to the mounting base, and a spring is adjustably provided on the lower side of the mounting base, and the tool base is slidably biased toward the pressing base by the adjusted spring pressure to press the wire rod. When the tool rest is attached to the stand, the tool rest is separated from the pressing stand against the spring pressure.

(Operation) In the wire rod coating peeling tool configured as described above, the center of the wire rod and the ridge of the blade are aligned and fixed, so that the tip of the blade always faces the center of the wire rod, and the pressing pad has two points.
Since the parallel rollers of the book are provided, the wire rod can be securely held in the horizontal direction, and even when the blade is rotated around the wire rod held by the roller, it is possible to prevent the spiral cutting.

Further, since the distance between the centers of the two rollers can be adjusted, it is possible to reliably hold the wire in the horizontal direction according to the thickness of the wire.

Further, since the pressing base is fixed to the mounting base and the mounting base is provided with a spring for constantly urging the tool base toward the pressing base side, it becomes possible to easily separate the tool base from the pressing base side when mounting the wire rod, The wire rod can be easily attached and detached, and the coating of the erected wire rod can be peeled off safely.
