Abstract
1,235,875. Forging. PELTZER & EHLERS. 10 June, 1968 [9 June, 1967], No. 27582/68. Heading B3H. An upsetting machine comprises a die slide 11 with a pair of roughing dies 2a, 2b, 3a, 3b at each side of a finishing die 4 so that bar stock can be rough formed in two steps or any even number of steps and finish formed in one or half the even number of steps. The slide has the dies 2, 3 mounted on a plate 19 which is oscillated by a cam 26 to bring either of the dies 2a or 2b into alignment with one length of stock and either of the dies 3b or 3a into alignment with another length, respectively. The stock is fed to the dies alternately and a blank sheared off. The blank is initially upset (5a), Fig. 1 (not shown), by the die 2a and rough headed in the second step by the die 2b. Between the strokes a second blank is introduced to be upset by the die 3a during the rough heading. On the next stroke the blank (5b) is transferred to the finishing die 4 for trimming and shearing, the blank (6a) is transferred for rough heading and a new blank (7) is introduced to the die (2a). The machine operates so that a blank is introduced alternately to the dies 2a, 3a and a finished blank ejected from the die 4 on each stroke. The slide 11 is reciprocated by a crank-shaft 13 with a flywheel 18. The crank-shaft is geared to the cam-shaft 20 and the cutting and feeding devices. The headed blank may be a screw bolt blank.
