METHOD FOR MANUFACTURE OF HOLLOW AXISYMMETRIC ARTICLES Russian patent published in 1998 - IPC

Abstract RU 2102178 C1

FIELD: plastic metal working, in particular, manufacture of articles with through holes. SUBSTANCE: method for manufacture of hollow axisymmetric articles from long materials with external contour of part formed in roller die by rolling out due to displaced material resulted from material deformation. Separation of finished part from blank is accomplished by twisting owing to mismatching of rotary speeds of blank and piecing punch and/or rollers. EFFECT: higher efficiency. 2 dwg
