Distortion of ring type parts during fine-blanking

Distortion control is one of the most important concerns of the metal processing industry, which also includes the fine-blanking technology. Fine-blanking of sheet metal involves metal flow and shearing, which result in complex deformation. Distortion occurs during the removal of parts from the tool due to the relaxation of internal stresses. Internal stresses that are generated during fine-blanking have an important effect on the shape and size of parts after fine-blanking. The distortion of ring type products during fine-blanking was analyzed by using dimension measurements, microscopic observation and numerical simulation

Precizno utiskivanje trake uključuje tok i rezanje materijala, što se odražava na složenost deformacije. Distorzija nastaje tijekom uklanjanja dijelova iz alata zbog oslobađanja unutarnjih naprezanja. Promjena oblika tijekom preciznog utiskivanja prstenova analizirana je mjerenjima dimenzija, mikroskopskim zapažanjima i numeričkim simulacijama
