Abstract

466,494. Punching and shearing. COLVILLES, Ltd., and HAND, T. W. Nov. 26, 1935, No. 32720. [Class 83 (iv)] Combined punching and shearing means is provided in a blanking-out machine the waste being severed so that it can be readily handled and cut up by short bladed machines. As shown, in a machine for blanking out wheel discs, a punch 3 and corresponding die 8 serve to produce in the metal a hole which is located by a spring pressed pin 34 in the centre of the blanking tool 4. A shear blade 5 on the punch head co-operates with a fixed blade 10, to cut the waste across a diameter of the punched hole. The punch 3 is secured in a support arranged in a recess 11 in a holder 2, the support being fixed by bolts which by adjustment of the blanking tool 4 and punch 3 can be spaced differently. The support is tapered at one end and flat at the other, oblique securing bolts being arranged to engage the taper surface. The blanking tool is in the form of a ring attached to a supporting ring 24 attached to the holder 2.
