Bulk forming technology of piston of disk brake
 Kiza, Jakub ; Jopek, Miroslav (oponent) ; Forejt, Milan (vedoucí práce)
The master’s thesis presents a proposal for the manufacturing technology of a disk brake piston made of material ČSN 41 2010 for a car brake caliper. Method of cold volume forming was chosen due to the production requirement of 200 000 parts per year, convenient axisymmetric shape of the part and required size tolerance. Based on study of chosen technology, production technique, which contains calibration and backward extrusion, was designed. Technological computations and optimalization of tool dimensions were done for the chosen production technique. The manufacturability of the part was verified by numerical simulation in Simufact Forming software. Because of unavailability of automatic cold forming machine designed for bigger sized parts on the market, the forming process is done by two forming tools with use of INWORK 700 hydraulic press. For the selected profit of 20 % the price for the part was set at 26,8 Kč. The turning point was determined as 52 745 pieces.
