Abstract

160,452. Krupp Akt.-Ges., F. March 8, 1920, [Convention date]. Rings.-A flat metal ring A is made cylindrical by a stamp, having conical and cylindrical parts E, e<1>, and a die F of such internal diameter, relative to the diameter and width of the ring A, that the resistance of the ring to the parts E and F balance so that the cone E passes through the ring which is drawn into the die, as shown in Fig. 7. The die F has a receass f<1> to receive the ring A, two-thirds to three-quarters of the width of the ring being unsupported. The stamp has a flange e<3> to engage the periphery of the ring towards the end of the process and an annular ejector G is provided. The sides of the cone E are inclined at 80‹ to 83‹ to its base.
