(54) DEVICE FOR ASSEMBLY

LARGE-SIZED SHELLS

SIZED GORLOVINA / AND

one

The invention relates to devices for the manufacture of large-sized rubber products, such as shells with end caps.

A device for assembling large-sized shells with end caps is known, comprising a mandrel formed by joining along longitudinal segments, which are made up of components along length 1.

In the manufacture of products on such a mandrel, labor-intensive non-mechanized operations take place, for example, excavation of all parts of the mandrel through the neck of the shell. In this case, the size of the necks must be sufficient to remove the collapsible elements of the mandrel from it, therefore reducing the size of the necks, as required by the operating conditions, such as fenders, is not possible.

These drawbacks are eliminated in the device containing an inflatable elastic chamber 2 mounted on the central tube.

However, the mandrel, made in the form of an elastic chamber, does not provide the necessary rigidity during assembly and rolling

structural elements of the product, which reduces the quality of products, and therefore is not applicable to obtain products of large diameter, for example, greater than m.

The aim of the invention is to increase

J product quality n expansion of technological capabilities of the device.

This is achieved by the fact that the device containing an inflatable elastic chamber mounted on the central tube is provided with an outer mandrel mounted concentrically to the tube consisting of two parts along the length, each of which is installed with the possibility of axial movement, is equipped with a mechanism for their movement and is formed by meridionally arranged hinges levers connected

 between each other with flexible material and equipped with mechanisms for their breeding, and also with the fact that each of the parts of the mandrel is pivotally connected with the mechanism for their axial movement, and the fact that the levers are associated with the mechanisms of their dilution

FIG. 1 shows a general view of the device; in FIG. 2 is a section A-A in FIG. 1. The device comprises an inflatable elastic chamber 3. mounted on the tube 2 installed by the ends in the hollow shafts 1. Outside the elastic chamber there is a mandrel mounted concentrically to the tube 2 consisting of two parts B and B. Each of the parts B and C is installed with the possibility of axial movement, is equipped with a mechanism for their intermingling and is formed by meridionally located hinged levers 4, interconnected by hinges 5 and flexible material 6, for example, a fabric with high strength characteristics. The extreme levers of each of the parts of the mandrel are pivotally connected through shafts 1 to the mechanisms of their movement and, by means of pulls 7, to pneumatic drives 8 for their dilution. The movement mechanisms include bearing housings 9 mounted with the possibility of reciprocating movement from the actuator 10 along the guides 11, and the shafts 1 are mounted on the subtypes of the housings 9. One of the shafts 1 is connected to its rotational drive 13. The device works as follows. In the initial position, the levers 4 divorced, and both parts of the B and C mandrel summed to each other. Compressed air is supplied to the internal cavity of chamber 3 through pipe 2, under the action of pressure of which elastic chamber 3 pulls the material 6 connecting the levers 4. Because the material 6 is closed, it corresponds to the configuration of the inner surface of both the spherical (elliptical) and cylindrical parts of the product, and the amount of air pressure in chamber 3 is sufficient to provide the required rigidity of the mandrel, then on the device prepared in this way it is possible to carry out a complete assembly cycle of the product. The application of layers of rubber and cords, their rolling with a mechanical roller (not shown in Fig.) Is performed while the mandrel is being rotated from the drive 13. After the assembly process is over; - Houses (not shown in Fig.) parts of the mandrel are removed from the product, for which air is released from chamber 3 and using pneumatic actuators 8, they reduce levers 4 to a position parallel to the longitudinal axis of the pipe. At the same time, the levers 4 also compress the material 6 and the chamber 3. Then, with the help of the actuators 10, the housing 9 bearing in the direction from the product is moved along the guides 11 until both parts B and C of the mandrel come out of the product. After that, the assembled product is put into any vulcanization form by any lifting device. A fitting (not shown in Fig.) Is sent to the vulcanization operation. The proposed design of a device for assembling large-sized rubber-cord shells with end caps increases the degree of mechanization of labor by eliminating time-consuming manual operations and reduces the deviation of the dimensions of products by providing the necessary rigidity during assembly. Claim 1. Device for assembling large-sized shells with end caps, containing an inflatable elastic cage mounted on the central tube, characterized in that, in order to improve the quality of the products, it is provided with an outer mandrel mounted concentrically to the tube, consisting of two parts each of which is installed with the possibility of axial movement, is equipped with a mechanism for their displacement and is formed by meridional arranged lever arms interconnected by bending materials and supplies mechanisms for their breeding. 2. The device according to claim 1, characterized in that each of the mandrel parts is hingedly connected to a mechanism for their axial movement. 3.
