Description

one

The invention relates to the processing of metals by pressure, in particular to the tooling for the manufacture of corrugated shells.

A device for bringing together 5 SIPHLE-GROSS corrugations, comprising a guide rod mounted on the base, a clamping and clamping jaws with a mechanism for their radial movement 1, is known.

However, the known device does not allow; the necessary quality of the bellows surface should be made after the corrugations come together because the clamping jaws are made of separate sections, at the junction of which the defects (stock-15 ki) are formed on the surface of the corrugations.

The purpose of the invention is to improve the quality of the BELLOWS.

To achieve this goal, the device is equipped with spring-loaded members mounted on the 20 guide rod, relative to each other and relative to the clamping and base cylinders with flanges having conical sections, the base and clamping are made in the form of full cylinders with conical surfaces on the ends, each clamping sponge made in the form of a corrugated disc spring and placed between the conical section 30

cylinder flange and one of the mentioned conical surfaces, and the mechanism of radial movement of each jaw is made in the form of a split, spring ring placed in the groove made on the cylinder flange, and wedges interacting with it, installed in the holes in the flange

FIG. 1 shows a schematic of the device, a general view (on the right — in the initial position, on the left — at the beginning of the crimp), in FIG. 2 — the assembly in FIG. 1 (at the beginning of the crimp); in fig. 3 — node c in FIG. 1 (in the initial position); in fig. 4 - section A-A in FIG. 1; in Fig, 5 - clamping sponge.

The device for bringing together 5frov 1 silbone 2 contains a stationary base 3 with a guide rod 4, clamping jaws 5 and a mechanism 6 for their radial movement, a clamp 7 and locking 8 position of the finger located opposite the clamping jaw 5. On the guide rod 4 there is an upper 9 and lower 10 cylinders with flanges having conical sections 11, on which clamping jaws 5 are arranged in the form of plate-jx corrugated springs. The flanges of the cylinders are grooves 12 and hole 13. The base 3 and the clamp 7 have the form of cylinders with conical surfaces 14 and 1b in contact with the corrugations of the clamping jaws 5. On the base 3 and the clamp 7, the sector wedge 16 of the jaws radially displaced mechanism is mounted, placed In the holes 13, In the grooves 12, spring rings 17 are installed.

The cylinders 9 and 10 are spring-loaded with respect to each other by a cup spring 18, and relative to the base and the clamp — by springs 19 and 20,

The stiffness of the spring 18 is greater than the stiffness of the spring 19 and 20, which ensures the gap between the jaws in the process of radial movement.

The device works as follows.

The prefabricated bellows 2 is installed in the working position, fixing the upper corrugation of the bellows 2 using clamps 8. With the help of special equipment, for example a press (not shown in the drawing), they act on the clamp. 7. In this case, the force through the spring 20, the cylinder 9, the spring 18, the cylinder 10 and the spring 19 is clamped on the base 3. Compression of the springs 19 and 20 causes; that the corrugations of the jaws 5, clamped by a mecuda with two conical surfaces, are straightened, moved apart, and at the same time the wedge 16 is unfolded split (spring rings 17, clamping jaws 5 radially move, covering the hollow of one of the corrugated bellows. and the clamping elements are brought together by crimping the trough of the corrugation of the bellows 2.

When removing the compressive load from the clamp 7, the springs 18, 19 and 20 unclench, the cylinders 9 and 10 together with the clamp 7 rise up, freeing the clamping jaws 5, which restore the original corrugated shape and decrease in diameter, the output from the hollows of the bellows 2 The clips 8 then release the bellows 2 to feed the next corrugation.

The convergence of subsequent corrugations is carried out in the same sequence.
