The purpose of the invention is to reduce the labor intensity of manufacturing and increase productivity. Orbital laying of the longitudinal reinforcement is made on two end rings having cylindrical protrusions. After winding, two collapsible bottoms are inserted inside the workpiece and local transverse reinforcement is wound around the cylindrical protrusions and bottoms. Next, the left and right rings are rotated relative to the central part to fit the reinforcement to the surfaces of the bottoms, then heat treatment is carried out to cut the left and right parts of the reinforcement along the ends of the product.

Description

The invention relates to the technology of manufacturing cylindrical vessels with bottoms of reinforced fibrous composite materials and can be used in the manufacture of aircraft, shipbuilding and transport ..

The purpose of the invention is to reduce the labor intensity of manufacturing and increase productivity.

The method of winding a cylindrical vessel with bottoms implemented in the next 5 sequences. The end rings I, having cylindrical protrusions 2, are set at a distance L, ensuring the manufacture of a product of a given size. The internal diameter di of the end rings of the lec 1 and the cylindrical protrusions 2 corresponds to the internal diameter of the product. End rings 1 are mounted on the machine, for example, in lunettes (not indicated), the lower rollers of which are driven to ensure the rotation of the end rings 1 with an angular velocity c. The machine has a swivel 3 with a roll of longitudinal reinforcement. From the drive, the swivel 3 rotates at an angular velocity. The IU moves at a velocity Vu along the forming product, making

orbital motion. Rotation of the end part dismantles parts 6–9 and their remotes 1 at a speed of 0) and orbital molding from the internal cavity of the product, movement of the swivel 3 with a roll ensures the proposed method of winding the vessel

The longitudinal installation of the reinforcement is made: cylindrical in shape with the bottoms allows 4 - the outer layer, 5 - the inner layer. 5 to be freed from destructible frames. The first stage of winding is completed when the tubes, the manufacture of which is the labor of the CMM process, also eliminate the operation of destroying the mandrel and its removal from the internal cavity of the product.

an inner layer 5 of reinforcement, technological equipment (end collar plates 6, the position of which is adjustable, collapsible bottoms) are reusable, which greatly simplifies

production. The absence of destructible mandrels in the proposed method allows

4,5 fittings are laid over the entire cylindrical surface of the end rings.

Further inside the cylinder formed

the composite rods 7 and 8 and the stops 9 are cast. After the dismountable bottom plates are installed, local transverse winding is carried out

Invention Formula The method of manufacturing the vessel is cylindrical. The operation is performed by twisting the form, including sequential longitudinal reinforcement 4, 5 in sections laying and tensioning the longitudinal and transverse between the end rings I and the dismountable reinforcement pre-impregnated with bottom bottoms 6. Twisting production 25 binder, and teJ) Microwave processing, in opposite directions (-fwK and characterized in that, in order to decrease - juice) due to the rotation of the end rings 1. laboriousness of manufacture and increase The process of twisting is carried out to fit performance, two end rings of the longitudinal reinforcement to the surfaces with cylindrical protrusions are wound boron bottoms 6 and the formation of pinches. orbital longitudinal reinforcement, in order to fit the longitudinal reinforced cylindrical billet of the insert 4 5 tightly, two collapsible bottoms are wound transversely, reinforcements 1 are fixed in the region of the collapsible ends of them onto the composite rods, starting from a predetermined bottom b after which it is carried out with a term for, in particular, a vessel, carried out transverse processing. In order to ensure the reeling of the reinforcement over the cylindrical constant tension of the longitudinal reinforcing protrusions of the end rings and the splitter 4 5 to the end rings 1 butt-. 35 bottoms, rotate the end wags of the tensile forces Q, which are round-shaped around the longitudinal axis of the vessel to ensuring adherence of the longitudinal reinforcement to the surfaces of the collapsible bottoms and the formation of a pinch, thermal give, for example, using a threaded device. Upon completion of heat treatment cut the longitudinal reinforcement. to process the product, cut off the sections of the armature 45 along sections aa and bb. Then, the elements before clamping, wind the transverse reinforcement, thermally process the product and remove the collapsible bottoms.  are transverse winding 12 to a predetermined wall thickness bi and carry out the final heat treatment.
