Abstract

The invention relates to electrical engineering, in particular to process equipment for preparing electrical cables for installation. The purpose of the invention is to simplify the design and ease of use. The tool for cutting the metal sheath of the cable includes a housing 1 with cutting means, two front guide elements, rear guide elements in the form of rollers 7 located on the axes 8, and a mechanism for pressing the cable to the cutting means. The front guide elements are made in the form of gears 5, and the cutting means are in the form of a disk knife 2. The disk knife 2 and gear wheels 5 are kinematically connected. The tool is designed to handle cables of various sizes, is simple in design and compact, and is also easy to use, since it is operated with one hand when cutting the cable. Coordination of the speeds of movement of the tool and cutting allows mechanization of the process of cutting the metal sheath of the cable. 2 hp ff, 3 ill.

The invention relates to process equipment for the preparation of electrical cables for installation and can be used in the power and electrical engineering industries.

The aim of the invention is to simplify the design and improve ease of use.

Fig. 1 shows a tool for cutting a metal cable sheath; in fig. 2 - the same, side view; Fig. 3 is a kinematic diagram of the instrument.

The tool includes a cutting unit consisting of a detachable body 1 (FIG. 1), a cutting tool of a disk knife 2 (for example, a milling cutter) mounted in the body 1 on the shaft 3 with the handle 4, the Knife 2 protrudes from the body. Upstream of the cutting knife, guides are installed in the form of a pair of gear wheels 5 mounted on the shaft 6, the shaft 3 of the disk knife and the shaft 6 are kinematically connected, for example, by a gear drive placed in the housing 1 (FIG. 3). The rear guides - a pair of disk rollers 7 - are fixed on the axis 8, mounted for movement in the slot 9 of the housing 1; In slot 9 there passes a screw 10, which interacts with its end with the axis 8; the knife 2 and the pair guides 5 and 7. And The tool also includes a bracket 12 with two C-shaped generators (FIG. 2) for covering the cable when longitudinally cutting the sheath (pos, T, fig, 1,2). Between the generators of the bracket 12 there is an opening 13 for laying the cable with the cross section (position II, fig, 2), at the base of the crown

12, there is a hole for a clamping screw 14 spaced in its case, at the end of which two pairs of disk rollers 15 (FIG. I, 2) are articulated, the axes of the rollers 15 are connected to the slats, and the slats by the intermediate axis 16 Screw 14 is mounted so that it can move and fix its position by means of a screw 17, for which recesses are made through the housing. gaps (not showing ano). The bracket 12 is attached to the housing 1 of the tool a; with the help of hooks 18 located on the body (fig. 2) and passing into the holes made in the upper part of the forming bracket 12.

The tool works as follows.

On the hooks 18 of the body 1 of the tool install a device for clamping the cable. For longitudinal cutting of the sheath, cable 11 is put (pos, 1, fig, 1, 2) onto rollers 15. Then cable M is pressed, for which purpose the presser screw 14 is moved and screw 17 fixes its position at which the gear wheels 5, circular knife 2 and disc rollers 7 touch the surface of the cable. The hinge installation of the rollers 15 at the end of the screw 14 ensures that not only the straight sections of the cable are clamped, but also uneven, bent. The disk knife 2 is installed to the depth of penetration into the metal sheath, for which the Vict 10 is screwed in, allowing the rollers 7 to be lifted. Rotate the handle 4, deepen the knife into the metal, screw the screw 14.

iibiM at a certain depth of cut (Fig. 1). To advance the device along the cable, rotate the handle A, mounted on the shaft 3 of the disk knife 2. Since the disk knife 2 is kinematically (gear) connected to the gear wheels 5, as the handle 4 is rotated, the wheels 5 also begin to rotate and the metal surface of the cable, evenly move the device, and the circular knife cuts the metal sheath,

For transverse cutting of the sheath, the cable is passed into the hole 13 of the bracket 12 and pressed by the rollers 15 with the screw 14 (pos. I, Fig. 2). The swinging movement is performed with the handle 4, with simultaneous pressing of the screw 14 to the slot of the metal sheath. Then, using the knob 4, the tool rotates around the cable. The sheath cut in the longitudinal and transverse directions is removed from the treated area.

The tool is simple in design and compact, since the disk knife 2 and the front guides made in the form of gear wheels 5 are interconnected kinematically, and the clamping device is removable. Applying the invention will improve the convenience of the tool in operation, as when cutting the cable it is operated with one hand, and the end of the cable is held with the free hand. The tool is designed for processing cables of various sizes. Harmonization of travel speeds 39

This method allows to mechanize the process of cutting the metal sheath of the cable.
