(54) PRESS FOR MANUFACTURING PRODUCTS FROM COMPOSITION MATERIALS

one

The invention relates to mechanical engineering and can be used in presses in the manufacture of ring-shaped products from composite materials.

A known press for the manufacture of products from composite materials, containing an annular matrix fixed on the frame, a pressing element and a hydraulic cylinder for moving it l.

A disadvantage of the known device is its low productivity.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that the press for manufacturing products made of composite materials, containing an annular matrix fixed on the frame, a pressing element and a hydraulic cylinder, is made plunger with a movable body, the tshunger is fixed on the frame, pressing

the element is mounted on the housing, the latter is mounted with the possibility. displacements along the hole of the annular matrix, and the cavity formed by the crush and inner walls of the matrix and the casing is connected with the displacement of the matrix.

The drawing shows the press section.

The press includes a housing 1, which houses the chamber 2 of the vacuum system and the outer cylinder 3 of the annular matrix. The inner cylinder 4 of the annular matrix is located in the center of the press and forms a closed

15 volume 5. The cylinder 4 through column 6 is mounted on the body 1 of the press. Inside the housing 4 there is an actuator consisting of a movable cylinder 7, gun 8 with a rod fixed on the housing 1. A plunger column 9 is rigidly mounted on the cylinder 7, carrying an annular disk 10, placed in the working volume of the matrix 11. 12. In the piston rod, the channels 13 and 14 are connected, connecting the rodless and rod end of the cylinder 7 with the hydraulic system. The volume 5 of the cylinder 4 communicates via channels 15 with the working volume 11 of the matrix of the internal cavity of the press through channels 16 and 17 connected to the systems for draining liquid components and vacuum, respectively (the diagrams are not shown in the drawing),

The press works as follows.

The slurry is fed into the rod end of the cylinder 7, the column 9 with the annular disk 10 is retracted to the lower extreme position. With the removal of the cap 12, the working volume 11 of the matrix is filled with a composite material. Close the lid 12 and seal it. The channel 15 is connected to the drain, and through the channel 13, the slurry is fed into the rodless cavity of the hydraulic cylinder 7. Under pressure from this mixture, the cylinder 7, column 9 and disk 10 are moved upward, the composite material is compressed, and the liquid components are squeezed and drain through the channel 16 to the system of their withdrawal. The air in volume 5 through the channels 15 enters and contributes to the removal of the liquid components. At the end of the compression, the channel 16 is sealed and the channel 17 is connected to the vacuum system, which ensures the final removal of the liquid

components from the product. Depressurize the device. Open the cover 1 2 and feed the cylinder 7 upwards to remove the finished product for further

processing.

Combining the pressing process with the removal of liquid components from the material of the product reduces the time for drying and provides an increase in

performance.
