Title: Method of and apparatus for reducing and elongating metal blanks
IPC: B21B1/42
Filed: 1938-02-21
Abstract: 499,075. Rolling. KRAUSE, F. R. Feb. 21, 1938, No. 5470. Convention date, Feb. 19, 1937. [Class 83 (iv)] A metal blank 32 is fed in step by step between a pair of rolls 17 which are oscillated over a portion of the blank by the oscillation of rollengaging top and bottom platens 12 also shaped to squeeze the rolls towards each other to reduce, hot or cold, an increment of the blank. After an increment of the blank is fed forward by a pusher 42 the blank is held firm by an automatically applied clamp 74 while the platens are pulled forward by crank operated rods coupled to the slidable housing 1 of the platens. During the return stroke of the mill the clamp is released and the carriage operates a valve to allow some fluid to escape from the front of a piston (49 not shown) under continuous fluid pressure which thereby feeds the blank another increment forward to be rolled down on the next stroke, and so on. The amount of feed is determined by the setting of the fluid release valve. The platens are so shaped that the last part of their surfaces are parallel so causing the rolls to roll the blank flat. The spacing of the platens from each other is set to suit the roll diameter and the thickness of the work. The rolls are urged apart by springs. Chains 39 around sprockets on the rolls give a smoother return of the roll carriage, and the springs 41 at one end restore the rolls to their original starting position relative to the platens. At the end of the return stroke pressure fluid is reversed to the front end of a retarding cylinder (97 not shown) by any known means, not shown, to hold the roll carriage stationary until the rolls are brought into good frictional engagement with the platens. In a modification one end of the chains is attached to an eccentric operated by the roll carriage to take up the slack.
