Abstract

593,383. Making compound bearings. GENERAL MOTORS CORPORATION. May 30, 1945, No. 13517. Convention date, June 16, 1944. [Classes 83 (ii) and 83 (iv)] Angular bending ; dies.-In an apparatus for forming bearings from flat blanks, a die having a semi-circular cavity co-operates with a punch of the same contour and having a predetermined clearance with the die, said punch having a resilient central portion which will deflect under forming pressure. The punch 24, Fig. 1, has a hole 32 drilled transversely so that a thin resilient portion is produced at its centre which, after forcing the blank 20, having a bearing layer and a steel backing, into the die block 22 deforms allowing further pressure to be applied around the sides of the punch to produce a bearing piece of even thickness. In modifications the punch may be formed from resin-bonded fabric, or may have more than one hole, or may be of steel with a reinforced resin surface of sufficient thickness to provide the required resiliency. Other plastic punches, such as those of hard rubber may be used. The punches are provided with backing-members 52 by which.they are mounted in the press.
