説明

The study deals with analysis for development of the hammering machine with the shock isolating anvil. It consists of the rigidly installed machine body and the elastically suspended anvil on the body or a rigid base. The anvil causes self synchronous impact motion with the hammer. Damping of the anvil system must be small for the active motion. A work is held at a constant colliding position by operator's hands on a guide table and given counterblow by them. The few important points of this isolation method are as follows : (1) The work must be light enough compared with the anvil. (2) Anvil ratio must be large, more than about 15, under condition that a damped natural frequency of the anvil system is lower than an exciting one. (3) If the ratio of these frequencies is adjusted to 1/2, the work receives impact at static equilibrium position of the anvil head. The feeling of work operation approaches to that in the case of a rigidly connected anvil.
