Abstract
1311038 Extruding ALLMANNA SVENSKA ELEKTRISKA AB 29 April 1971 [30 April 1970] 12079/71 Heading B3P A hydrostatic extrusion press has a pressure chamber with an axially slidable billet holder 15 provided with a relief valve 18 and which separates the chamber into two parts 16a, 16b and the chamber part 16a is pressurized so that the valve does not open during billet loading and after the chamber is closed by the die 9 the pressure is increased to open the valve and hydrostatically pressurize the billet. The pressure is supplied and controlled by a pair of pumps 37a, 38a with different pressure outputs which are selectively connected to the chamber part 16a, Fig. 10, as in Specification 1,311,037 or by a single pump 72a, Fig. 14. In the latter embodiment the fluid line to the chamber part 16a has a high pressure relief valve 74 and a low pressure relief valve 77 which is connected to the fluid line by a valve 79. The pressure in the chamber part 16a is thus kept low until the valve 79 is closed. The hydrostatic fluid is cooled after extrusion as in Specification 1,311,037. The billet is overheated before it is loaded into the chamber to allow for cooling. (For Figures see next column)
