Description

The invention relates to process equipment for the preparation of cables for installation and can be used in the communications, electrical and radio engineering industries in the manufacture of automation and computer facilities. A device for treating a high-frequency cable is known, which comprises a knife for annular isolation cut and a knife for longitudinal isolation cut. The knives are mounted on a rotatable holder that allows the knives 1 to be used alternately. However, this device is a manual device in which the stripping process from the cable consists of two successive operations, which reduces its performance and does not allow the use of wire processing machines. . The closest in technical essence to the invention is a device for removing the casing from electric cables, which contains main and additional knives mounted on the casing, and the additional knife cuts the casing and thus facilitates the operation of the main knife 2. A disadvantage of the known device is incomplete incision of the casing with a knife , which results in low quality stripping. The aim of the invention is to improve the quality of cable processing by completely breaking off the insulation from the shielding braid. This goal is achieved by the fact that in the device for stripping insulation from the cable containing the main and additional knives mounted on the body, the cutting edge of the additional knife is made by intersecting the front and front concave surface at an acute angle, and the edges of the cutting edges of both knives are located in a plane perpendicular to the feed axis of the cable. In this case, the acute angle formed by the intersection of the end and front concave surfaces is 70-75 °. FIG. 1 shows the device section; in fig. 2 - the device is in working position; in fig. 3 - the relative position of the main and additional knives; in fig. 4 - main knife, general view; in fig. 5 - additional knife, general view. The device for removing the outer insulation from the cable contains a rotating head 1, in the channel 2 of which, by means of a permanent magnet 3, a spring 4 and a screw 5, a main blade 6 is installed for undercutting the insulation. In the head 1 by means of a screw 7, a d, additional knife 8 is fixed for removing the insulation. A guide tube 10 is pressed into the hole 9 of the head 1 with a stop 11 and a locking screw 12 for setting the stripping length of the cable 13. The cable feeding unit 14 has a spring 16 clamped by a spring 15 and a handle 17 for inserting the cable 13 into the hole 9 of the head I. Head 1 is driven in rotation by the electric motor 18 through the gearbox 19. The device for removing the outer insulation works as follows. The main knife 6 is set to the required cutting depth with the screw 5. The additional knife 8 is installed to the required diameter of the cable 13 with the screw 7. The working head 1 is driven by the electric motor 18. The cable 13, pressed by the clamp 16 of the feed unit 14, is turned is fed into the opening 9 of the rotating head I, where the knife 6 enters the insulation of the cable 13 and cuts it in a spiral. Then, during the rotation of the head, the additional knife 8, with its upper edge of the cutting edge, goes under the insulation, separates it from the shielding braid, and with its upper concave surface guides the insulation away from the cable. The cable 13 to be processed, being moved, falls into the guide tube 10 and reaches the stop I1, which determines the required length of the cable stripping. When the cable 13 reaches the stop 11, the knife 6 makes an annular incision of the insulation. At the same time, the additional knife 8 tears off the insulation cut by the knife 6 and it falls out of the head. Node 14 feed cable 13 leads the cable from the treatment area. The insulated cable 13 enters the hopper. The efficiency of the proposed device in comparison with the known ones is that it allows processing high-frequency cable in the complex processing machine with high performance and significantly improves the quality of the processed cables of any diameter.
