Bulk forming technology of cases
Covrighin, Sergiu ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
Bc. COVRIGHIN Sergiu. Bulk forming technology of cases. Diploma thesis in fifth class of master studies, academic year 2009/2010, study group 5M/68, FME UT in Brno, Institute of Manufacturing Technology, Department of Metal Forming, May 2010, pages 46 , 18 fig., 7 tab., 4 annexes. In diploma thesis is introduced a technological proposal regarding production of cases by bulk forming from cemented steel 14 220.3. Despite the estimated number of parts which is 70000 a year, quality and product accuracy, 2 options of technological procedures concerning cold bulk forming wth combination of backward and forward extrusion are being considered. For chosen option are elaborated technological calculations. As for the suggested technology, crank press, force 8000 kN and made by company KRUPP was chosen. Material for extruder is steel 19 569 and material for extrusion die is steel 19 655.
