发明名称 METHOD AND THERMOEXTRUDER FOR PRODUCTION OF EXTRUSION FORCE
摘要 metallurgy, in particular plastic metal working, applicable for extrusion of blanks. SUBSTANCE: the method consists in the fact that for provision of a longitudinal force and longitudinal running of the cross-head with the punch a force is exerted to it in the direction of displacement to the product that is subject to deformation. The mentioned force and running are obtained due to rod heating on condition that its end opposite the end of the position of the punch is fixed in the extruder against displacement along its longitudinal axis. The thermoextruder offered in accordance with the method has a rod with a cross-head and a punch on its unfixed end and is provided with a device for heating the rod to 600 C. EFFECT: expanded facilities realizing the extrusion forces, simplified construction. 5 cl, 19 dwg
