(54) DEVICE FOR CLOSING TYPE OF SINTERS

The invention relates to the processing of metals by pressure and, in particular, to accessories for the manufacture of bellows.

It is known a device for bringing together snofl corrugations, comprising a caliber mounted on the bottom plate, consisting of alternately installed wedge-mating sections of two kinds, with one of the kinds of sections of the intersection line of the wedge planes lying on the outside of the gauge, and the other with . internal, as well as the mechanism for moving sections, made in the form of a central stop, and wedges 1 mounted on the top plate.

Since the movement mechanism in the known device contains two types of wedges interacting with the corresponding types of sections, and taking into account that the wedges must have sufficient rigidity, the whole mechanism has large dimensions and can only be used for large-size bellows.

The purpose of the invention is to ensure the convergence of corrugations of small bellows due to the reduction of the dimensions of the mechanism

moving sections. For this purpose, the central stop is fixed on the top plate and connected with wedges interacting with sections, the intersection lines of the wedge-like surfaces of which lie on the outside of the caliber.

In order to design the hollow of each corrugation in the form of a hollow bulb on the working planes of sections, grooves equidistant to their outer surface are made.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view along YY of FIG. one; in fig. 3 shows the node I in FIG. one.

The device contains a section caliber, in the section of which 1 intersection line of the wedge planes lie on the outside of the caliber, and in sections 2 from the internal, sections 1 and 2 are installed alternately on the lining 3 of the base 4 and move along pin m 5 and 6 installed in slats 7. The sections are returned to their original position by means of springs 8 and 9 located in the grooves of the base 4 and connected to sections 1 and 2 by means of shtyry 10 and 11. The base 4 is fixed on the fixed plate 1.2. Each section 1, 2 consists respectively of the upper 13, 14 and lower 15, J6 parts (sponges), which are movably interconnected by means of the help and screws 17 and are spring-loaded to each other by springs 18.

A central stop 20 with a wedge 21 fixed on it and a clamp 22 is mounted on the topner of the movable plate 19 of the device.

The wedge 21 is placed against the sections, the lines of intersection of the wedge surfaces of which lie on the outside of the caliber. .

On the bottom plate 12, clamps 23 are diametrically opposed to each other, designed to properly install the snone 24. On the working planes of sections 13, 15 and 14, 16, the outer surfaces of the grooves 25 and 26, respectively, are equidistant.

The device works as follows.

The bellows 24 is installed in the latches 23, while the depression of the converging corrugation is located opposite the gap between the sections 13, 15, And 16, and the sections. 1 and 2. Plate 19 is lowered, while a wedge 21 pushes sections 1 of calibers, which in turn move sections 2 of calibers, while springs 8 and 9 are compressed. In the extended state, sections 1 and 2 form the working surfaces of parts 13, 15 and 14, 16, two closed surfaces without gaps, grasping the depression of the approaching corrugation from above and below.

Upon further movement, the plate 19 with the help of the clamp 22 acts on the upper parts 13 and 15 of sections 1 and 2, which, moving down to the stop on the lower 14 and 16 parts, squeeze the corrugation cavity, reducing its radius and the corrugation pitch and giving her form of a hollow thin-walled bulba. The springs 18 are compressed.

During the reverse course of the plate 19, the upper parts 13 and 15 of sections 1 and 2 under the action of the springs 18 return to their original upper position. As the moving plate 19 moves upward, the wedge 21 comes out of the engagement with sections 1 and those, under the action of the springs 8, return to the original

the position, simultaneously under the action of the springs 9, returns to the initial position of section 2, releasing the bellows.

The clips 23 are retracted, the bellows 24 is released and moved downward relative to sections 1 and 2 to the jaw to bring the next corrugation closer.

The closure cycle is repeated.

The use of the invention allows to significantly simplify the design of the device, since all wedges have the same configuration, and their number is reduced in comparison with the known devices.
