The invention relates to the processing of metals by pressure, in particular to devices for bending rings at the ends of wires.

The aim of the invention is to expand the technological capabilities of the device.

FIG. 1 shows schematically the proposed device, a general view; in fig. 2 and 3 - technological transitions of making a ring at the end of the wire; in fig. 4 is a view A of FIG. one.

The device consists of 2 slider 2 installed on the base 1, bending levers 3 and pivoting relative to the axis 4 of the wire feeder 5 6. Two pivot mandrels 11 pasHbJx diameters are mounted on the slider 2 two swiveling about axes 7 and 8 and on the plate 10 there are two copiers 12. The bending levers 3 are mounted rotatably with respect to the axes 13, with one ends of the levers being operative, and the others have the ability to interact with the copiers 12. The slider 2 is placed in the guide frame. Plates 9 and 10 in the working position are fixed by means of a clamp 14, and the wire to be processed is fixed by a limiting sector 15.

The device works as follows.

By turning the plate 9 around the axis 7, the mandrel II is required for the diameter of the ring to be made. In accordance with the diameter of the wire 6, turning the plate 10 around the axis 8 sets the required copier 12. By turning the stop 5 relative to the axis 4, the required length of the supplied wire 6 is established. Plates 9 and 10 are fixed in the working position with

clamps 14. The stripped end of the wire 6 is inserted between the mandrel 11 and the restrictive sector 15 until it stops 5. Then a drive mechanism (not shown) is turned on, which actuates the slider 2. Moving together with the slider 2, the mandrel 11 grips the wire 6 and bends it between the working ends of the levers 3 to form a semiring. With further movement of the slide 2, the copier 12 interacts with the working ends of the levers 3, which, moving around the axes 13, complete the formation of a ring. The restriction sector 15 does not allow the wire 6 to move out of the work area. After

In this case, the slider 2 with the mandrels 11, the limiting sector 15 and the copiers 12, as well as the bending levers 3, return to their original position.
