SU40936A1 - Hinge machine at the ends of steel cables - Google Patents

Description

The work on the formation of loops at the ends of steel cables to the present time is usually done by successively pushing apart individual cable runs at the splicing point and successively inserting the strands of the loose cable end into distant places. After crimping the spliced area with hammer blows, the wire is wrapped outside.

According to the invention, the machine mechanizes the process of making loops by unwinding the cable at the splicing point with successive dilution of individual strands with two shoulders with one arm at the ends equipped with hooks for gripping the strands and others for hooking them with a ring; then, in diluted strands, they are laid at the end of the cable in such an order that they should lie with a normally curled cable; thereafter, the cable is twisted, again with the simultaneous tension of the ends of the strands. In addition, in the same machine, a device is provided for winding the point of spliced cable strands with wire.

In FIG. 1 shows a front view of the machine with a partial cut; FIG. 2 is a vertical section along the line AB of FIG. one.

On the left stand / machine base there is a clamp 2 for the cable 3 being processed, which can move the cable along the stand in the direction of the longitudinal axis with the screw 4. In the clip 2 itself there is a screw 5 that serves to move the part b, fitted on top with a recess in which the cable 3 is inserted To the part b of the clamp 2 are attached the cables 7. On the right stand of the 8th bed there is a bearing 5. bearing sleeve / C of the disk 7 /, in which the shaft 72 with the handle 13 is rotatably mounted. The latter is provided with a ratchet wheel M located in double dog coupling / 5, swivel on the rack 8. At the left end of the shaft 72, a clip / b is mounted, at the end of which there is a clip 77c with a screw to the same end of the clip 75 one end of a curved steel tape 7 I is attached, the second end of which is bent in a trough towards the clip 77 and carries block with a notch for the stop end of the screw 20, located at the other end of the skby 76.

On the disk 77, the rim 22 is freely mounted on the rollers 27 and has curved edges onto which a wire is wound before the machine is operated, which is used to wind the spliced loop of the cable. The axles of the support rollers 27 are held with earrings 23 fastened to the rim 22.

On the side surface of the disk, the holder 24 with a cut opening for roller 25 is fastened. The holder 2- / has a hinged cover hinged on hook 26. At the outside of the roller 25, the stem 27 is mounted freely with guide and tension rollers 28, 29 for the winding wire, and at the end is rigid, the lever 50 with a weight 57, made in the form of a handle. When the machine is operating, the wiring is worn on the cable being machined, and of the middle part and the double-arm levers 32 pivoting on it, the number of which is determined by the number of wires. In order to simultaneously rotate all the levers 32, one shoulder of the latter carries the ring 33. Both the ring 33 and the middle of the wiring have cutouts for placing the cable in the center of the wiring. The other ends of the arms 32 have pointed ribs and hooks to grip the strands of the cable.

At the beginning of the operation of the machine, the ring 33 is shifted to the right and the levers 32, pressed by the springs 34, enter in the perineum between the straight cable ends with pointed edges. The screw 35 on the handle 13 serves to stop the rotation by screwing the sleeve W into the body; at the same time, the doggie 15 is pulled in one direction by the spring 36, in the other - by the pull 57, going to the handle or the foot pedal.

To perform work on the proposed machine, the cable is fixed in clips 2 and 17. The end of the cable at clip 77 is bent into a loop of the required shape and placed inside the bracket 16 and tape 19. If the loop is made with a hook, screw 20 is tensioned onto the cable. Further, an additional cable is clamped near the splicing point with forceps, which can be placed on the rod 27; the handle 75 rotates the shaft with the clamp 16, and thus the cable is unfolded. The loose wires are gripped by the ends of the levers 52 and are moved to the left by moving the ring 55 to the left to form a brchkoobrazny profile. Then, the ends of the cable are inserted in the perineum between the extended legs and fastened to the ends of the cable.

Moving with the help of the screw 5 of part 6, which at the beginning of the work was

moved on the cable guide axis to the right, the nested strands are tensioned, and the shaft is pulled back by the handle 75 by reverse rotation of the cable; before reversing the ring 55 and slightly turning around the axis of the cable, the levers 52 are pulled out of engagement with the straps, since all the hooks on the levers 52 are bent in one direction, opposite the movement of the strands when the cable is unwound, and are retracted to the left. Then the ends of the strands are trimmed and the spacing is wound. The winding wire, running off the rim 22, bypasses one roller, goes to another roller 28, rounds in rollers in order of chess the rollers 29 and is attached to the cable at the point where winding starts. When the disk 77 is rotated together with the rim 22, the wire will be wound on a cable, and the rim 22 will have a slight movement along the disk 77 as the wire runs down. At each turn of the disk 77, the roller 25 under the influence of the load 57 will rotate one turn around its axis and move towards the disk one step of its thread. The lower end of the rod 27 is constantly pressed against the wire by the wire tension. If the thread pitch on the roller 25 is equal to the diameter of the winding wire, the winding turns to the correct splicing point of the cable.

The subject matter of the invention.

1. A machine for making loops at the ends of steel cables, characterized in that for the purpose of breeding untwisted cable strands serve two shoulders levers 52, one shoulders of which are equipped with hooks, designed to grip the cable strands, and others to breed them by moving the ring 55. 2. In the machine tool according to claim 1, use the wire winding device at the spliced place of the cable mounted on the rotary disk 77 and connected to the latter with the help of a screw 25 that carries the weight for turning to supply the device for each disk 77 rotation.
