Production manner and the vibration-proof bush, and pushing pressure tool of the barrel and the vibration-proof bush which were processed due to the process manner and this manner of the destal of the barrel

摘要

As the barrel (1) on the end face (8) of one destal (21) side, the surface which in pushing pressure tool (7) is provided it does coarsely and pushes the operation department (9), pushing pressure tool (7), as the barrel (1) conical locus or almost drawn conical locus around the axis (O), turning, it is process manner of the destal of the barrel where it expands processes the end face (8) and the surface does coarsely and processes.
