Description

one

The invention relates to the manufacture of wire products, in particular to winding current coils for electricity meters and other electrical measuring instruments.

A machine for manufacturing articles made from wire is known, which contains mechanisms for feeding, straightening, cutting the wire, two mechanisms for forming the ends of the workpiece, each of which is molded in the form of a mandrel and a bending roller rigidly mounted on a driving rotary disk, as well as a mechanism for central bending of the workpiece. , the transfer mechanism of the workpiece from one mechanism for forming the ends of the workpiece to another and the resetter. However, this machine has limited technological capabilities.

To expand the technological capabilities in the proposed machine, each mechanism for forming the ends of the workpiece is equipped with a spring-loaded lever mounted on the frame that can be rotated, at the end of which a pusher is fixed; a cam connected rigidly to the rotary disk, interacting with a spring-loaded lever, and a driving clamp mounted on the frame mounted with the possibility of reciprocating movement in

radial direction relative to oravka.

FIG. 1 is given the kinematic scheme of the described automaton; FIG. 2 - mechanism for forming the ends of the workpiece in a square coil; in fig. 3 - finished product in three projections.

The automat starts moving from the electric motor 1. Through a belt drive 2, the rotation is not affected by the gearbox 3, which by means of a transfer circuit 4 transmits the rotation to the drive shaft 5.

From the coil 6, through the mechanism of stripping 7, which receives rotation through the belt drive 8 from the gearbox 3, the rollers 9 of the pulling mechanism 10 pull the wire - a blank of the required length. The pulling mechanism 10 receives movement from the drive shaft 5 through the rocker mechanism 11. The pulling mechanism, moving to the right, while pulling the wire, frees the ears 12 cutting-twisting mechanism, which encloses under the action of the spring 13, and the wire enters it. The cutting-twist mechanism 12 of the crowns receives movement from the drive shaft 5 through the cams 14 and the lever system 15. First, the wire is cut by the knives 16 in the middle of the area previously stripped of the insulation, and then the ears are twisted. Stripping mechanism 7

is set so that during the cutting of the wire and the twisting of the ears, it is cleaned.

The stripping mechanism is located from the cutting-twisting mechanism of the ears at a distance equal to the length of the wire — the workpiece. After twisting the lugs, the pulling mechanism 10 returns to its original position, tilting back the lash-twisting mechanism. In this case, the cut wire billet with twisted ears with the help of mechanical arms 17, which receive movement from cam 18 through lever 19, is transferred to the middle zone of the machine gun and is installed in grips of mechanism 20.

The middle part of the billet wire enters the central bend mechanism 21, which receives movement from the cam 22 through the levers 23. The central bend mechanism performs the central bend, and the bending mechanisms 24 and 25 bend both of the billet wires. The bending mechanisms receive movement from the cam 26. By turning the wire-billet mechanism 20, the billet molding mechanisms 27 and 28 are transferred into a square coil, and the billet transfer mechanism 29 is transferred from one molding mechanism to another.

The wire blank 30 is pressed against the mandrel 31. By the movement of the rack 32, the toothed roller coaxially mounted on the same shaft with the rotary disk 33 with the bending roller 34 rigidly fixed on it, and bends the wire blank. After bending the movement: with the toothed rack 32, the toothed roller is rotated to its original position. The clamp 30 is retracted, releasing

wire preparation. The rotary disk 33, returning to its initial position, releases the cam 35 with the cam 35, which, under the action of the spring 37, rotates together with

mounted on the end of the pusher 38. The pusher 38 moves, giving the wire billet for a certain length, after which the process is repeated until the end of the molding of the left side of the square roll. Similarly, the right part of the coil is molded by the forging mechanism 28, after which the ready coil is dropped into the container.
