Manufacturing of Motorcycle Sprocket
Hrazdíra, Michal ; Podaný, Kamil (referee) ; Řiháček, Jan (advisor)
The work focuses on the production of a motorcycle sprocket, which transfers the torque from the output shaft of the gearbox to the rear disk of the wheel. Steel 12 050 was chosen for the production of the component, which is suitable for the intended purpose. The sprocket, produced in a series of 80,000 pieces per year, has a diameter of 191.9 mm and a thickness of 5 mm. After considering all factors, fine blanking with v-ring was selected as the manufacturing method. For this series, a semi-finished product in the form of a coil was chosen, which has an outer diameter of 1,400 mm and a width of 204 mm. For the annual production batch, 59 full coils and one incomplete coil will be required. Before the actual tool design, technological and control calculations were performed to verify the functionality of the proposed cutter. The tool was supplemented with technical documentation and a detailed description of the construction. Based on the calculated values, a triple-action hydraulic press Feintool HFA 11,000 plus was designed, which is part of the production line, which also includes decoiling and straightening equipment.
Production Possibilities of Press Brakes
Hrazdíra, Michal ; Jopek, Miroslav (referee) ; Řiháček, Jan (advisor)
The bachelor thesis deals with the production possibilities of press brakes. This is a literary research, in which the aim of the work is to describe the principle of bending. It also focuses on common and special tools and their use in engineering practice. The first part of the work is focused on general bending technology, which discusses the basic principles and possibilities of this method. The main chapter is the bending itself, where the individual types of machines, their components, tools and clamping systems are introduced and described. Furthermore, modern tools and their application in engineering practice are presented. In the last part, the production of the switchboard cabinet is presented on a CNC press brake.
