| description | Invention relates to the press for forming pipes of large diameter of the sheets into U-shaped cylindrical billet with the slit, which consists of several gap presses straight arranged in one row, which corresponds to the length of molded pipes of large diameter, each of which includes lower tool and upper tool performing vertical reciprocating travel with the help of hydraulic cylinders. Hydraulic cylinders are made as the cylinders of fast motion with an auxiliary piston in the form of a rod directed in the cylinder housing located in the centre on or in the main piston of larger diameter, and having channels for bringing the pressure means to the piston surface of auxiliary piston, and also from the annular surface of the main piston without auxiliary piston. The invention provides for reduction of overall dimensions of the press and reduction of oil consumption. |
