Producing big rage shell
Doležel, Martin ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
The bachelor's thesis presents a proposal for the technological process of production of a big rage shell, the semi-finished product of which is a circular roundel made of non-alloy steel DD11. Based on the study part and the subsequent technological part, drawing without wall thinning and with wall thinning is proposed. The drawing is carried out on a hydraulic progressive six operating press PO 400 P with a forming force of 4,000 kN. Cutting of blanks is performed on an eccentric press LE 400 D. One part of this thesis is the design of a tool for drawing without thinning the wall and a tool for the last operation of drawing with thinning the wall. These tools are made of 19,436 steel according to the drawing documentation.
