Claims

[Scope of claims for utility model registration] An impact cylinder having the following configurations (a) to (f). (a) A cylinder body that has a pressure chamber inside, a reduced diameter pressure chamber that is open to the pressure chamber in the head, and an operating chamber that is separated from the pressure chamber at the end; (b) The above-mentioned cylinder body. It is slidably inserted into the cylinder body, partitions the pressure chamber into a first pressure chamber on the head side and a second pressure chamber on the end side, and is slidably fitted into the diameter-reduced pressure chamber. (c) a ram provided with a protruding portion, (c) slidably inserted into the working chamber, one end protruding into the second pressure chamber, the other end protruding outside the cylinder body, and a tool insertion portion provided at the protruding end; (d) a spring biasing the shaft in a direction to protrude from the cylinder body; (e) a spring attached to the cylinder body and having the second shaft;
(f) an exhaust valve that opens the pressure chamber to the atmosphere; (f) a first switching position in which the valve body provided on the outer periphery of the shaft in the working chamber is returned to its original state by the biasing force of a spring, and the pressure of the shaft; and a second switching position that is switched in conjunction with the sliding movement toward the chamber, and in the first switching position,
High pressure air from a high pressure air source is passed through a pressure reducing valve to a second
In the second switching position, high pressure air is supplied to the first pressure chamber and the exhaust valve is opened to the atmosphere. A switching valve that opens and shuts off the supply of high pressure air to the second pressure chamber.
