Abstract

787,694. Stamping. ECKOLD, W. Sept. 19, 1955, No. 26782/55. Class 83 (4). In a punch and die assembly for deforming sheet metal, the punch comprises resilient material held in a case which is resiliently attached to a holder. The holder 1 has a cylindrical projection 2 around which seats a bush comprising two steel sleeves 3, 3<SP>1</SP> each bonded to an intermediate rubber bush 4. Mounted on the outer sleeve 3<SP>1</SP> is a tubular casing 5, the upper part of which is filled with a metal disc 6 and a rubber plug 7. In operation, the upper end of the casing 5 forms a work-holder or clamping ring, while the rubber plug 7 presses the metal 12 into a concave die 10 to form a hemispherical projection 13.
