Die forging
Stračánek, Rostislav ; Šlais, Miroslav (referee) ; Lidmila, Zdeněk (advisor)
This diploma thesis is based on proposal of manufacturing technology forging of connection rod by die forging. The connection rod is made of 12 050 steel and it is part of crank mechanism in combustion engine. Production series was specified to 120 000 pcs. for year. Into technology procedure was implemented method of cross wedge rolling before die forging. The material for transverse cross wedge rolling was chosen 19 554 steel. Process of die forging was selected three operation in vertical forging press LZK 4000 with pressure force 40 MN made by company Šmeral Brno a.s. For die material was chosen 19 552 steel. And finally was carried out technical and economical evaluation of the forging production.

Forging gear
Šíma, Vojtěch ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated in a frame of Bachelor‘s studies branch B-STG presents a technology design of a forged piece – gear wheel by drop forging. The wheel is made form 12 050.0 material and is a part of an agriculture machine. Considering the series of 45 000 pieces per a year and the precision of production, the drop forging for three operations was selected for production. The wheel will be produced on the crank drawing inclinable press LKZ 1600 P from Šmeral Brno, a.s. producer with nominal tensile force 16 MN. Swages are made of alloyed instrumental steel 19 552.8. At the end of the project technical economic evaluation of production and comparison of the forging technology and machining technology was implemented.
