Production of tool for pressing formed shim into flange
Kolář, Milan ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
The Baccalaureate Thesis deals with the design of a tool for fixing of thrust rings in flanges of high pressure fuel injection pumps. The theoretical part of the final project summarizes both theory-based and cold metal and alloy working-based knowledge. Three options of fixing the thrust ring in the flange of a high pressure fuel injection pump have been developed. Based on tests carried out, the option II has been chosen for repairs of fuel injection pumps flanges since it seems to be the most advantageous one. The high pressure fuel injection pump flange is made of AlSilMgMn aluminium alloy. The thrust ring is made by C 75 sheet steel stamping according to DIN 17222 (ČSN 12081). The tool drawing was made on the basis of the best-fit technology repair option. Stamping tools are made of 19 452 steel and hardened to HRC 60-4. The assumed yearly output amounts to 7000 pieces. A special purpose machine is used for repairing fuel injection pump flanges.
