Process for massive forming of metal hollow profile starting workpieces |
abstract |
The invention relates to a method for massive forming of the metal hollow profile starting workpieces, a starting workpiece being introduced into the interior of a molding tool and the inner contour of the molding tool being transferred to the workpiece under the action of a pressure medium pressed into the interior of the workpiece. DOLLAR A task is to provide a method of the type mentioned at the outset, with which the necessary high deformation pressure is generated in a technically advantageous and effective manner and the pressure medium under high pressure is introduced into the starting workpiece located in the mold. DOLLAR A According to the invention, using an injection molding machine for plastics, an elastic and / or plastic or a solid pressure medium is filled into the material hopper and then injected under pressure into the interior of the starting workpiece located in the closed mold. DOLLAR A The field of application of the invention is the massive forming of metallic workpieces using high-pressure media, whereby workpieces with more or less complicated shapes can be produced during cold or hot forming. |
