FIELD: technological processes.
SUBSTANCE: invention relates to metal forming, namely, to die tooling intended for drawing square-shaped sheet workpieces. On lower plate there are poles, on which intermediate plate with cutting blade and guide planks is fixed. On top plate male die with rectangular male die for section and female drawing die is fixed. At the same time on clamp there are stencils, thickness of which exceeds thickness of sheet square billet. In the T-shaped slots of the clamp there located are H-shaped sliders with a side surface made at an angle. There is also a buffer device with pushers.
EFFECT: higher quality of shells due to reduced formation of bit in hollow shell during drawing.
