The increase in the carrying capacity of KAMAZ vehicles necessitates the use of heavyduty hot-rolled thick-sheet rolled products made of microalloyed steels with a high yield strength for the production of sheet stamping. The development of the production of such parts faces problems of ensuring stampability, which requires finding ways to increase it both in the metallurgical and machine-building processing of rolled products. Based on expert assessments of specialists, generalization of production experience, modeling of plastic flow in sheet stamping operations, field experiments, the thinning deformations responsible for the appearance of defective signs (cracks excessive refinement) in stamped parts are estimated. The influence of the parameters of the processed material, workpiece, technology on the deformation of thinning is established, the directions of increasing the stampability on a specific part “Bracket” are shown.
