The invention relates to the processing of metals by pressure, in particular to devices for assembling flexible parts.

The closest to the proposed technical essence and the achieved result is a device for assembling flexible parts, containing bending elements mounted on the body in the form of levers with a drive for their rotation and a pressure fl.

However, when assembled on a known device, the coating of bending edges and brittle non-metallic parts is not preserved during their assembly with parts made of sheet material.

The purpose of the invention is to improve the quality by preventing damage to the coating of bending edges and the destruction of brittle non-metallic parts when assembling them with sheet metal parts.

The goal is achieved by the fact that the device for assembling flexible parts containing bending elements on the body bending elements in the form of levers with a drive for their rotation and clamping, is equipped with bending pads with annular grooves, bending levers are made with annular projections placed in these grooves and mounted on the clamp, and the clamp is spring-loaded relative to the body, while the drive of movement of the bending pads is made in the form of fingers mounted on the body and leads placed on the bending pads with the possibility of interaction Twi with fingers.

The device is also equipped with an adjustable stop for clamping, made in the form of a rack with a threaded hole and a screw with a lock nut screwed into it.

FIG. 1 shows the device, a general view; in fig. 2 - the same, from the side of the adjustable stop; in Fig. 3, section A-A in Fig. one; in fig. 4 is a section BB in FIG. one.

The device comprises a housing 1 with a drive for moving it 2 and a clamp 3 mounted inside the housing, in the slots of which (not shown) the bending levers 4 are hinged. At the ends of the 5 levers there are bending pads b connected by rods. The pads are made with annular grooves 8, in which the levers 4 are installed with their annular projections 9. The levers on the side facing the wall 10 of the body 1 have bevels 11. In the walls 10 of the body grooves 12 are made, in which the stops 13 are mounted, fixed on the clamp 3 Bending pads are connected through their drivers 14 by tension springs 15 with limiting points 13. A compression spring 16 is installed between the case and the clamp. To adjust the pressure of the clamp, an adjustable stop 17 fixed to the base 18 is installed. and 19.

The device works as follows.

The assembled set 20 of height H is mounted on the stand 19 by the folded edges 21 downwards and on top of it the drive 2 described device is brought to it. After the replaceable pad 22 of the clamping 3 rests into the assembled set 20, together with the levers and pads stops its movement, and the body 1 continues its movement and with its walls 10 moves the levers in the direction of the folded edges, affecting the bevels 11 of the levers. Upon contact of the pads with the edged edges of the casing wall, the pads 6 are rotated through the leads 14 and the edges are folded. At the same time, since the axis of rotation of the pads approximately coincides with the axis of curvature of the bending edges, and the size B is equal to the width of the assembled set, the slipping of the shoe relative to the bending edge will not occur, and consequently, damage to its cover.

When assembling parts, one of which is fragile, the clamping force is limited by means of an adjustable stop 17.
