ROTARY WHEEL TYPE METAL EXTRUDING FORMING DEVICE

摘要

PURPOSE:To prevent generation of bubbles in the metal and to prevent lowering of quality in a metal extruding forming device by deaerating the air in powdery granular material. CONSTITUTION:A metallic formed product is extruded from the hole of a shoe 2 by rotating a rotary wheel 1. At the same time, a vacuum pump 6 is operated to start deaeration. As the airtight material supply tank 4 is connected to a material supplying hole 32 and an extruding passage 3, air in powdery granular material 5 is deaerated from a suction side duct 61. Suction of powdery granular material by air in the channel 3 is prevented by a projection 31, and the passage is connected to a suction hole 37 and the suction side duct 61 of the vacuum pump 6. Accordingly, air in this space is also deaerated.
