Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a sheath cutter used for stripping coating of cables and cabtire cords.

(Prior Art) Electric equipment, cables having a large wire diameter used for indoor / outdoor wiring, cabtire cords, and the like have a thick coating (hereinafter referred to as a sheath) so that they cannot be easily peeled off.

Therefore, in the sheath peeling work, conventionally, a sharp knife such as an electric knife was used to make a cut with the knife at the location where the sheath is peeled from the end of the cable, and then while applying force to that location, cut the blade along the circumference of the cable. The sheath was peeled off by turning.

(Problems to be solved by the invention) However, in this conventional method, although it is simple, the inner conductor is damaged, the sheath is left uncut, or the blade is rotated once depending on the force of inserting the blade into the sheath. Occasionally, there was a problem that the start and end of cutting did not match.

(Means for Solving the Problem) In order to solve such a problem, in the present invention, a blade for cutting off a coating, a bracket for holding the blade,
A knife guard for protecting the blade, a plate provided with a groove for accommodating the knife guard, a bracket for mounting the bracket and the plate, an adjusting screw for setting the position of the blade, and a tightening screw, the knife The problem was solved by installing the guard, the groove of the plate and the blade so that they are aligned with the median line.

(Operation) The sheath is cut by the cable passing over the fixed blade while rotating.

(Embodiment) An embodiment of the sheath cutter according to the present invention will be described below with reference to the drawings.

FIG. 1 is a front view and FIG. 2 is a side view.

In the figure, 1 is a sheath cutter of the present invention, which has the following configuration. Reference numeral 2 denotes a bracket in which both ends of a rectangular plate on the longitudinal direction are bent in opposite directions, and the brackets face each other in the longitudinal direction. 3 is also a bracket in which both ends of the rectangular plate on the longitudinal direction are bent to each other. The brackets are opposed to each other in the longitudinal direction, a blade 6 is inserted between them and tightened with a mounting screw 7, and the other piece is attached to the bracket 2. Tightening screw 8 on the side
Tighten. Reference numeral 4 is a knife guard formed by forming a rectangular plate into a U-shape with a brim, which protects the blade 6 and the operator, and inserts a cable of a certain width in the longitudinal center of the U-shaped bent portion. A groove 11 is provided. Reference numeral 5 denotes a plate in which a groove having a convex cross section at a right angle to the longitudinal direction is hollowed out in the longitudinal direction.
Insert it, cover it on the bracket 2 and attach it with the attachment screw 10. By doing so, the knife guard 4 can freely move in the longitudinal direction in the groove formed by cutting out the convex shape of the plate 5. Reference numeral 9 is an adjusting screw for adjusting the position of the blade 6.

The operation method of the sheath cutter 1 configured as described above will be described. As described above, the parts are assembled and the mounting screws (7, 10) are assembled.
Is tightened firmly so as not to move, and the tightening screw 8 and the adjusting screw 9 are loosened at first.

Then, the tightening screw 8 and the adjusting screw 9 are adjusted according to the thickness of the sheath 21 to be stripped of the cable 20, and the blade 6 is tightly tightened so as to protrude above the plate 5. This adjustment moves the blade 6 up and down depending on the thickness of the sheath 21, but when the thickness of the sheath 21 is 2 mm, for example, it is set to 2 mm or slightly shorter than the thickness.

By the tightening after the above adjustment, the blade 6 is fixed at the set position.

Next, the knife guard 4 is pulled out to the front (the side in FIG. 2A), the cable 20 is inserted into the cable insertion groove 11, and the position of the sheath 21 to be cut is aligned with the position of the blade 6.

In this way, when the cable 20 is pushed forward while rotating (FIG. 2B), the knife guard 4 moves forward (in the direction of the arrow in FIG. 2) along with it, and the sheath 21 is cut by the blade 6 and rotates once. When this is done, the sheath will be cut by the blade 6.

The sheath 21 can then be easily removed by pulling it to the left and right with your hand.

The sheath 21 can be cut from the cable 20 by the above operation.

By preparing several types of cable insertion groove widths and changing the setting of the blade position depending on the thickness of the sheath, it is possible to cope with the work of stripping cables of various thicknesses.

In the present embodiment, the plate is of a fixed type, but it can be attached / detached. For example, if the portion on the morning side (Fig. 2A) is attachable / detachable, various types of knife guards can be replaced in a short time. It can be used for stripping cables of various thicknesses.

By attaching this sheath cutter to the rootstock, more stable work can be expected.

(Effects of the Invention) As described above, the sheath cutter according to the present invention has a simple structure and cuts the sheath while fixing the sheath cutter and rotating the cable. It is possible to prepare. Also, since the force can be applied to the average, there is no uncut portion of the sheath or damage to the inner conductor.
