FIELD: plastic working of metal, namely apparatuses for producing shells of thin-sheet steel.
SUBSTANCE: bending machine is designed for producing shells with round and non-round cross section from thin-sheet steel with thickness up to 0.8 mm and length up to 2000 mm. Bending machine includes hollow bending rolls having slit along its length, apparatus for controlling distance between rolls, driving mechanism and apparatus for forcing blank. The last are arranged in cavity of rolls; each apparatus is in the form of pressure cleat and spring.
EFFECT: enhanced efficiency of machine, improved quality of shells.
