Flex disk brake in a press machine

摘要

A brake assembly includes a flex disk brake secured to a brake device of a press clutch-brake combination. A plurality of axially flexible finger elements extends from a peripheral side of the flex disk in a bent or arcuate configuration. The finger elements extend at least in part in a circumferential direction of the flex disk generally opposite to a direction of rotation of the press crankshaft. Each finger element is secured at one end to the stationary press crown. During brake activation, the axial flexibility of each finger element accommodates axial displacement of the attached brake device as the brake device undergoes actuated movement into its braking position. The flex brake disk provides a torquing rigidity that renders it rotationally stationary.
