Description

srigL

The invention relates to technological equipment for the preparation of coaxial to white for installation and can be used in the electrical industry.

The aim of the invention is to identify the performance and quality of cable processing.

FIG. 1 shows the proposed device, a general view; in fig. 2 - kinematic diagram of the device.

The device for cutting the ends of coaxial cables contains a base 1, on which a lock washer is installed in G1odilia 1niki, made in the form of a nonsung sleeve 2, kinematically connected with drive 3 (Fig. 2). A disk 4 with a hole 5 and pressed-in fingers 6 are welded to the end of the sleeve 2, on which the head 7 with a knife 8 is fixed by means of a lock to remove the outer insulation from the cable. Knife

8 performed with two edges

9 and 10, located in one plane perpendicular to one another.

In the disk 4, two glasses 11 are diametrically mounted. In each of them, the body 12 is freely installed without a gap with means for removing the metal braid from the cable. In the housing 12, a milling cutter 14 and a knife 15 are fixed in the spindle 13, which, together with (the cutter 14), cuts off the metal braid. A spring-loaded rod is fixed on the housing 12. 18 with a tapered roller 19. On the base 1, a nut 20 is installed, in which the cam 21 is located. On the inside cam of the cam 21, the roller 19 rotates the disk 4 of the roller 4. In the hole of the disk 4 and inside the sleeve 2 node to remove the inner insulation from the cable to which contains two shaped knives 22 and a system of levers fixed in the guide bases 1, and means for setting the length of stripping of the inner insulation from the cable. The device works as follows.,

A knife 8 for removing outer insulation with adjustment screws is installed and fixed at the depth of cut depending on the diameter of the cable being processed. The length of the outer insulation to be removed with respect to the treatment plane of the metal braid is determined by means of the cutters 4 using stops 1) placed on the quick-detachable head 7. The adjustment of the cutters 14 to the specified diameter of the metal braid is deflated by rotating the cam 21 in the nut 20. Cam 2 along the thread moves-, with in the axial direction. In this case, the rod: 18, connected with a comical roller 19 with a cam 21, changes its radial position and (.11io turns around

rotation of the housing 12, you have with whom you change your floor () cutter 14 at each node to remove the metal body. In this way, the distance between (jipe times depending on the diameter of machining- BaeMoi o cable) is changed.

The amount of removal of the inner insulation with respect to the plane of the removal of the onlet by means of cutters 14 regulates the intermixing of the sleeve 2 along the guides 23 made in the shape of a dovetail tail.

When turned on; 1: a: zatron, ird) 3, the sleeve 2 with the disk 4 rotates. The cable to be processed is closed in a hand-held gun (not shown) and inserted into the opening of the rotating head 7 with the knife 8 to remove the outer insulation. . When the cable is axially moved, the cutting edge 10 makes an annular cut of the outer insulation, and the cutting edge 9 separates it from the metal braid. The cable is then moved to the metal braid removal zone. In this case, the milling cutters 14 rotate in the spindle 13, which receives rotation through the screw pair 16 and the pinwheel 24 from the fixed njecTepHn 17. Simultaneously, the milling cutters 14 rotate around the axis; the housings 12 rotate around the cable to meet its axial shifts. The milling cutters 14 use their metal sheaths to lift the metal sheath, and cut them with knives 15. When this occurs, the circular milling of the metal screen to a predetermined length. At the same time, the knives 8 continue to remove the outer insulation for a given length. When the disk 4 rotates, the rollers about roll the inner surface of the cam 21 and roll them through the spring-loaded rod 18 to fix the specified distance between the milling cutters 14.

After the gun abuts base 1, the axial movement of the cable is terminated. The removal of the outer insulation and the metal braid is completed.

 A pneumatic actuator of the inner insulation stripper, connected to the shaped knives 22, is then included, which moves towards the cable and, when removed, cuts the internal insulation of the cable. Then the air drive is turned off. The knives 22 rotate to their original position, while removing the inner insulation from the cable. The treated cable is removed from the device and the gun.

The implementation of each node for removing the metal braid in the housing, on which a spring-loaded rod is fixed with a tapered roller running around the inside surface of the cam, allows adjustment of the specified distance between cutters depending on the diameter of the cable being processed, since the housing is connected a spindle in which a mill is installed. Such

Ion constructive performance; It will be used to add a rsgu.prosdn element and other rotating parts to remove the metal braid, which completely eliminates the possibility of dropping FI chips, and the following does not cause jamming of the regulating and charging parts. As a result, the time of simple equipment 1 for unplanned repairs, as well as the frequency of preventive maintenance of equipment, which leads to a reduction in scrap and increased productivity, is significantly reduced.

Constructive placement of a floating blade with a knife on the disk with a sleeve to remove the outer insulation and cutters with knives to remove the metal braid ensures that the removal of the outer insulation and the metal braid are combined in time, which reduces the processing time of the cable.

Placing the node to remove internal insulation in the disc hole provides for the formation of a three-stage working zone of the cable in one feed to the device, and installing the node with the possibility of reciprocating movement - adjusting it to the specified size of the internal insulation to be removed, thereby achieving universality of the device with a significant reduction in time for preparatory and final operations, which also improves the performance of the cable treatment process and provides spine of the device in the automated production line installation.

kami creates conditions for simultaneous cutting of the outer insulation and its separation from the metal braid, which excludes the fixing, reproducing and blocking of the node, since the insulation simultaneously removes the; c from the treatment area, while excluding it. getting into the treatment area of the metal braid cutters.

In addition, such an implementation of the knife allows an increase in the cable feed rate, which makes it possible to combine the removal of the outer and metal cells, since the removal of the metal braid is a process of cold metal processing that requires certain cutting conditions.
