The invention allows to simplify the process of removing the shell and cover with cable. 2 S. and 2 C.p. f-crystals, 6 ill.

The invention relates to a relatively new field of technology - methods and devices for removing the cover and shell cable products, the most common of which is the cable.

The main parts of the cable are three: 1) core - conductive core; 2) the shell closest to the core layers; 3) the cover, which is made up of other, outer layers: armor, winding, braiding, screen filler, insulating material and other elements of the cable.

In the emerging large scale described a new area of technology has been popular for three main reasons. First - stremel is the need for cutting large quantities of cable with the military (but sometimes and civilian objects on the core and waste the shell and cover. Further from the core to extract valuable components in the form of non-ferrous metals, lead and other Third reason: the development of the field of cutting the cable is pushed ecological situation on the planet, which is all the more saglasitsa garbage man-made activities. The scale of production of cable products can be indirectly estimated by the fact that the list of Standards on products in the collection of standards is several hundred.

In the patent and technical literature information about methods and devices for removing the shell and cover with cable gland, possibly due to the secrecy of production.

All this shows the need to develop methods and devices that provide for the removal from the cable outer layers of the cover and the shell.

Known methods for removal of the cover and the sheath of the cable containing the feed cable, the introduction of means of cutting and moving them along the cable, and destruction are only the outer layers of the cable. As a means of cutting using a cutting torch, an abrasive, milling machine and other metal cutting tools (literature no data). The disadvantages of these methods is the presence of chips or melting of the cable is I, they wound on the core is very tight, that even in the case of partial notching the greater part of the thickness of the layers remaining portion is ruptured (burst) due to internal stress.

At the same time, there is a technical field, somewhat similar to cutting the cable is the area cut pipes. The similarity is primarily intended purpose, which is in the handling long items (pipes, bars, and so on), which include cable products.

The technical essence is the closest to the claimed proposal known methods and devices for cutting pipes wedge disc blades, widely described in the patent and in the literature (for example, "pipe Cutting into blanks" authors Chizhik-Polaco Century B. and others, ozonation plants as well, series C-3, 1976, M., UDC 621.937; 669-462). In this source on page 20, 22, 37-43 provides methods and devices for cutting pipes by pushing V-disc knives when testing relative to the tube in a plane perpendicular to its longitudinal axis.

By construction, such a device is a housing on which are mounted annular faceplate with the tracing tracks, the rotation mechanism of the faceplate, the feeder length storagename to move the shaft with wedge disc blades, installed on the bearings in the carriage equidistant about the axis of the faceplate.

The purpose of this invention is to provide a new method of removal of the cable cover and the shell, and the development of a device for implementing the method.

This goal is achieved by the fact that the way of removing the cover and the sheath of the cable containing the feed cable, the implementation of cutting tools and their movement along the cable are made so that the introduction and movement of cutting tools is pushing V-disk knives and longitudinal testing their cable parallel to its surface to a depth corresponding to the thickness of the layers of the cover and shell taking into account the elastic flexibility of the cable materials.

The device for implementing the method, comprising a housing and mounted therein annular faceplate with the tracing tracks, the rotation mechanism of the faceplate, the feed mechanism of long products coaxially plate, the carriage and the rollers parallel to the axis of the faceplate and interacting with its photo-tracks to move the shaft with wedge disc blades mounted on bearings in the carriage equidistant about the axis of the faceplate, made so that everyone but the from which the knife is the magnitude of the radius of the cable core with regard to the elastic flexibility of the cable materials, each carriage is made in the form of a plate which is provided with a boss under the bearings blade shaft hole finger, associated with the housing and parallel to the axis of the faceplate, and means fixing plate on the housing. The mechanism of rotation of the faceplate is made in the form of a rod, one end of which is pivotally connected with the faceplate, the other end is fixed to the flywheel, and on the rod threaded section that interacts with the nut installed on the housing can be rotated around the round shank of the nut, the axis of which is parallel to the axis of the faceplate, and the faceplate is equipped with the risk, and the case is a graduated scale that indicates the diameter of the cable core and taking into account the elastic flexibility of the cable materials. Means for recording each carriage on the casing as several passing through holes in the carriage and the slots on the chassis screws, the head of each of which is mounted on the carriage, and the threaded end is screwed a nut inserted in her arms.

The claimed method is illustrated in the drawings Fig.1 and 2, which shows two projections of the principal technological scheme of the process of removing the cover and the sheath of the cable To: Fig.1 is a view of the end of the cable To the commencement of cutting and shell in the form of tapes L and the release of the core C.

To simplify shows cable with round cross-section, which means cutting R equally distant from the axis of the cable and can be evenly spaced around the circumference, although this is not required. Binding is only the symmetrical arrangement of means P (to balance the design of the device embodying the way) relative to the transverse axis OO, passing through one of the elements means cutting R. as a means of cutting used wedge disc blades, located on the shafts in the bearings with the possibility of free or forced rotation. The number of knives should not be less than two. In the drawings illustrating the proposed method and the device shows the application of three knives.

The method is implemented as follows.

Cable To be submitted by the mechanism P in cutting tools R - V disc blades mounted about the longitudinal axis of the cable at a distance of the radius of the core of the cable, that's why when supply is pushing knives into the surface of the cable and the longitudinal forging their cable parallel to its surface to a depth of T corresponding to the thickness of the layers of the cover and shell taking into account the elastic flexibility of the cable materials. Because the manufacture is and I fall, without requiring any additional effort and money in the form of scrapers, etc., In case of incomplete cutting knives remnants of the thickness of the cover and the shell, even burst from established with the winding their tension. Cut the cover and shell belts L (their number is equal to the number of knives) hanging down under its own weight and removed.

The device for realization of the proposed method is shown in Fig.3-6: Fig.3 is a front perspective view of the device on the output side of the cable core and separated from him tapes of the cover and the shell; Fig. 4 is a perspective view of the device from the back side, where the supply cable in the device of Fig.5 - section b-B (Fig.3), and Fig.6-section b-B (Fig.4).

The device includes a housing 1 and mounted thereon annular faceplate 2 (inserted in the bore of the housing 1 can be rotated with the tracing paths "a", the rotation mechanism 3 of table 2, the feed mechanism 4 cable and three carriage 5, each of which carries bolotoobraznyh finger 6 and the roller 7, parallel to the axis of the faceplate 2, and the V-disc knife 8. The finger 6 is connected with the housing 1 and is the axis of rotation of the carriage 5. The platen 7 communicates with the tracing path "and" faceplate 2 to rotate the carriage 5 around your finger 6. Each V-drive is emeny evenly circumferentially equidistant about the axis of the faceplate 2, sludge from it by the value of the radius of the cable core with regard to the elastic flexibility of the cable materials. Each knife 8 has an individual motor for rotation in the form of the coupling 11 and the motor 12 and is mounted so that the plane of the tops of the blade of the wedge parallel to the axis of the faceplate 2.

Each carriage 5 is a plate provided with a lug "b" under the bearings 10 of the shaft 9 and the holes of the sleeve 13, which are placed in the finger 6, the platen 7 and the means of fixation of the plate on the housing 1 in an adjusted position. Fixation means made in the form of several (3 for each carriage) bolts 14 passing through the sleeve 13 of the carriage 5 and the grooves "in" on the housing 1. The head of each screw 14 fixedly mounted on the carriage 5, and the threaded end of the screw 14 is screwed a nut 15 inserted in her arms 16 (there may be one or several of the drawings shows two on each screw 14).

The rotation mechanism 3 faceplate 2 is a shaft 17, one end of which is connected with the faceplate 2 hinge 18, and the other end fixed to the flywheel 19. The rod 17 has a threaded section "g", interacting with a nut 20 mounted on the body 1 can be rotated around its round shank 21. Palyam rod 17 by means of a handwheel 19. The amount of rotation is determined by the combination of risks "d" on the face plate 2 with the corresponding notch 22, fixed to the body 1. Scale divisions 22 denote the diameter of the cable core and take into account the elastic flexibility of the cable materials.

The feed mechanism 4 in the form of, for example, roll feed (see schematic illustration in Fig.4) is located on the back side of the device and provides a continuous moving cable knives 8.

In preparing the device for operation, you must first adjust the distance from the knives 8 to the axis of the faceplate 2. To do this, turn all knobs 16 loosen the fixation of the carriage 5 on the housing 1. Then rotate the flywheel 19, carrying the rotating faceplate 2 simultaneous rotation of all of the carriages 5, and thus the knives 8, to the required value. Upon completion of the adjustment, lock the carriage 5 on the body 1 by the rotation of the arms 16. The end of the cable is charged into the feed mechanism 4. The unit is ready for operation.

The device operates as follows.

Include a rotational drive of the knives 8 and the feeding mechanism 4. The latter feeds the cable into the blades 8. Rotating drive the knives 8 are pressed into the cover and the shell (at a depth of T, see Fig.1) in tangential longitudinal forging and cut and separated even when partial cutting, torn from internal stress.

The resulting core and tape the outer layers can be processed further by standing next to the equipment or transported for this purpose - it is reasonable to reel in the view of the Bay. The ribbon cover and the shell can chop up into small pieces, for example, on a drum scissors, which makes the waste is very compact and transportable.

The process of removing the cover and the sheath of the cable by the proposed method and device are very productive, especially with the use of the unwinding and winding device. The simplest such device is a shaft freely or forcibly rotating on the bearings in the uprights of the U-shaped frame.
