The air stamp hammer is an air stamp hammer that applies an appropriate number of drain suction ports around the piston rod on the cylinder tube side of the gap where the piston rod passes through the cylinder tube of the pneumatic cylinder. An ejector part whose diameter increases in the direction of drain collection is formed in the drain recovery path leading to the outside of the stamp hammer, an ejector nozzle is arranged in the ejector part, and high pressure air for cylinder driving is supplied to the pneumatic cylinder. A drain recovery device for an air stamp hammer, comprising a conduit path for supplying part of the exhaust air taken out from the exhaust pipe to the ejector nozzle.

Claims

[Scope of utility model registration request]

An air stamp hammer that uses a pneumatic cylinder that drives the piston rod to drop an upper forging die suspended on a piston rod against a fixed lower forging die, thereby performing cold forging of an object between the two dies. An appropriate number of drain suction ports are opened around the piston rod on the cylinder tube side of the gap where the piston rod passes through the cylinder tube of the pneumatic cylinder, and the drain suction ports are led to the outside of the air stamp hammer. An ejector part is formed in the drain recovery path that increases in diameter toward the drain recovery direction, and an ejector nozzle is arranged in the ejector part. A drain recovery device for an air stamp hammer, comprising a conduit path for supplying part of the exhaust air taken out from the pipe to the ejector nozzle.
