ンマの緩衝装置。 A buffer device installed at the lower part of the anvil of the air stamp hammer, comprising an air spring mechanism that supports the anvil and absorbs hammer pressurization impact, and an air flow rate adjustment tank that adjusts the internal pressure of the air spring mechanism. It includes an air flow rate adjustment valve that controls air flow between the air spring mechanism and the air flow rate adjustment tank, and this air flow rate adjustment valve is opened by the pressure increase upon impact of the hammer pressurization of the air spring mechanism, and the air spring is closed. It has a slide valve body that communicates the mechanism with the air flow rate adjustment tank, and a small diameter air supply path in the center of the slide valve body that allows air to be supplied from the air flow rate adjustment tank to the air spring mechanism even when the valve is closed. Buffer device for air stamp hammer.
