METHOD FOR MAKING COMPLEX-SHAPE ARTICLES Russian patent published in 2004 - IPC

Abstract RU 2224612 C1

FIELD: machine engineering, metallurgy, possibly in hardware branch for making complex-shape articles such as railway-road rod type clamps in the form of ω character. SUBSTANCE: method comprises steps of feeding initial elongated blank; placing it in shaping position; cutting measured-length rod by means of fixed cutting off tool; and shaping article; feeding new rod-type blank whose length consists 0.85 - 0.99 of length of initial rod blank, placing it in shaping position asymmetrically at adjoining fixed cutting-off tool and large length portion of blank equal to half length value of initial rod blank; after cutting off shifting rod to shaping position by value equal to difference half of large-length portion and small-length portion of rod due to additionally feeding it. EFFECT: enlarged assortment of articles of desired shape due to possibility of centering rod at changing its length. 2 dwg, 1 ex
