THE DEVELOPMENT OF THE TECHNOLOGY OF MANUFACTURE OF THE HOLLOW CYLINDRICAL FORGINGS MADE FROM CENTRIFUGE-CAST BLANKS BY PRESSING

The object of investigation: the process of pressing of the hollow cylindrical forgins. Ther performed designs have been justified on the application of method of the slip line for the description of the flat stress-deformed condition of the blank with the two-side pressing. The analytical dependences, describing the specific forces with the blank two-side pressing by the punch travel, have been obtained as well as the dependences for the description of variation of the value, the direction of the metal flow speed. The new technology of pressing of the hollow cylindrical forgins from the centrifugal-cast blanks, ensuring the capacity increase by 3 - 5 times, decrease of the tool materials consumption by 2 - 3 times and economy of material, has been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
