Abstract

393,484. Stamping. BUDD MANUFACTURING CO., E. G., 2500, Hunting Park Avenue, Philadelphia, U.S.A.-(Assignees of Hochreiter, E. and McGary, F. E. ; c/o Budd Manufacturing Co., 25th Street, Philadelphia, U.S.A.) Nov. 11, 1932, No. 31897. Convention date, Dec. 19, 1931. [Classes 83 (ii) and 83 (iv).] In the stamping of large irregularly shaped articles, e.g. automobile fenders, from sheet - metal blanks requiring extensive and slight drawing operations the excess metal in the region of minimum draw 27 is withdrawn during the die forming operation. As shown, this is effected by a plunger E and projection 40. The projection 40 is secured to the upper die C but the die E slides in a die B which surrounds the die C and clamps the edges of the sheet-metal blank against the lower die A. The die E and also an ascending lower die D are operated from the die C by means of camended slides &c. 34, 33 and 25, 21. The edges of the blank with the depressions formed by the die and projection E, 40 are afterwards trimmed off.
