It is known that during long-term operation of crank machines for cold sheet stamping, which consists in cyclic loading of the structure with mechanical stresses, fatigue degradation of the metal occurs, leading to the occurrence and growth of cracks

In crank presses, an important role is played by the presence of actuators with dwell, in which, with continuous movement of the input links, the output working link remains stationary at some part of the work. The use of a high-class structural grou
