Abstract

1,146,730. Cutting-out presses. E. V. HENC. 20 Sept., 1966, No. 41936/66. Heading B4B. [Also in Division B3] A cutting blade B, Figs. 1 and 4, for a die press comprises a flat bar having a shank portion 41 and an edge deformed to provide a plurality of notches and protrusions on each side forming a corrugated-like edge which when ground at an angle to the medial plane of the shank portion defines a cutting edge 43 and is characterized by a plurality of side by side teeth 50, each tooth having an arcuate scallop-like cutting edge portion 52 terminating at each end in a sharp point 51, each tooth having a flat tapered side face portion 54 on one side and an indenture 56 on the opposite side having a tapered side face portion 58 at the top thereof, alternate teeth having the indenture in one side face and the teeth between alternate teeth having the indenture in the opposite side face. The shank portion 41 is provided with a plurality of keyhole slots 59. A die press 10, Fig. 12, incorporating the blade B comprises a resilient anvil 14 mounted on a stationary support 12 and a platen 16 having means including a member 24 for mounting the blade B, the platen being operable by an hydraulic actuator H. Resilient strippers 40 are provided to strip the cut-out blank and the waste from the cutting edge of the blade.
