Piston rod eye production

The bachelor's project elaborated design of technology production of the piston rod eye in series of 45 000 pieces. The piston rod eye is made of steel rod C45E by die forging. Pursuant to of the literary pursuit and necessary technological calculations was chosen a pneumatic – hydraulic hammer KHZ 4A, from the company called Šmeral, with a forming energy of 50 kJ, for forging of component. Cross wedge rolling machine was chosen for overdosage of forged piece in form of double piece. Shearing press LKOA 200, from the company called Šmeral, with a forming force of 2 000 kN, was chosen for shearing of forged piece. At the end, the technical – economic evaluation of material costs was calculated
