Abstract

316,514. Rhodes, C. J. Feb, 15, 1929. Cupping.-A press for drawing sheet metal has the drawring 4 supported by pins 5 and a table 61 which moves under the resistance of a buffer 13 applied through bell-cranks 9 linked to the table at 8. The linkage is designed to compensate the varying resistance of the buffer by the varying leverage during drawing, so that a substantial constant pressure is applied to the draw-ring. The bell crank may be arranged to apply pressure to the lower end of the buffer.
