6 stabilisation of the concealment plunger of sub-gun 15, which are interconnected by pipes 18. The presence of the 21 cylinder ensures not only the forward movement of container 3 with respect to the pressure stamp 4, but also the automatic redistribution of forces between them in the required ratio. In addition, the installation of the 15-cylinder stabilization adds a press capacity proportional to its area. Furthermore, the movement of the press stamp and container is carried out by one main working drive 13. For blank runs and container return, a separate drive 26 and 27 is installed on the front cross. The design of a subsurface plunger with a bottom 69 which is arranged in the cavity of the plunger 14 of the main cylinder 13 makes it possible to significantly reduce the dimensions of a pressing cross-arm with a support cylinder. Picture 1 - Horizontal hydraulic press with «rigid» hydraulic connection of its movable elements for pressing with active action of friction forces: 1 - blank; 2 - container sleeve; 3 - container; 4; 23 - short press; 5 - matrix; 7 - blank supply mechanism; 8, 24 - mobile cross-arms; 9, 19, 20, 46, 47, 48, 49, 50, 51, 65, 66, 67 - controllable and uncontrolled valves; 10 - stand; 11 - front cross-section; 12 - rear cross-section; 13, 14, 35 - main power cylinder; 15, 16 - stabilising cylinders; 17 - columns; 18, 72 - pipelines and channels; 21, 22, 68, 70,71 - sub-cylinder; 25 - stop; 26, 27, 28, 29 - cylinders of container movement; 30 - front cross-section window; 31 - Shlinton; 32 - Knife; 33 - Squeezing device; 34, 38 - High-pressure pipeline; 36 - Filling valve; 37 - Low pressure line pipeline; 39, 40, 41 - Distribution device; 42, 43, 44, 45 - Pressure and return cylinders; 52, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64 - Automatic throttling device; 69 - the centring tail of the propeller piston; 70, 71 - the inner cavity of the propeller cylinder; 72 - the channels in the propeller cylinder To automatically obtain the required value of the kinematic coefficient (KW=VK/VPR) The ratio between the speed of the VK container and the VDP pressure stamp and the reliable operation of the press units during the extrusion process requires the execution of various structural elements of the press in strict compliance with each other. Thus, in order to exclude the multiplication of pressure in the inner cavity of the 21-cylinder, the area of the cross-section of the sub-piston 22 shall be equal to the total area of the cross-sections of all the power cylinders carrying out the movement of the cross-arm 8. The movement of the cross-arm 8, The plungers of the 14 power cylinders |
