METHOD OF MAKING A CLAMP

摘要

A method of making a clamp used for a supercharger in an internal combustion engine is initiated by cutting out an unworked clamp half from a plate material. The half is then formed such that it is semicircular in front elevation and the opposite ends extend outwardly. Other clamp half is made in the same manner. An unworked link is cut out from a plate material and then its plane strain is corrected. Further, the link is chamfered and hardened. The halves are arranged in circle and the worked link is inserted into one ends of the halves. Finally, these ends are curled around the link.
