Design of bulk cold forming technology for bicycle part
Kubíček, Lubomír ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The diploma thesis is dealt with a project of a new manufacture method of a bicycle´s part. The part is a brake drum, which is the necessary part of a free-running charge. In an intro-duction of the diploma thesis is described a nowdays manufacture technology and its deficiencies. According to the nowdays manufacture technology was designed a new one, which is based on a cold volumetric shanking. The shanked hemihedron is consequently shaped according to the current technology. After the operation of cold shaping an instrument is projected. The project of the shaping technology is filled up by the calculation of the essential parameters, including an arrangement of the instrument and the process. An economical evaluation of the new process of the brake drum is stated and its advantages and disadvantaged were selected.
