Application of air hammer

Nov. 04, 2019

Air hammer is a kind of equipment widely used in ironmaking, mainly used for forging billet into shape.Air hammer has the advantages of simple structure, low investment cost and convenient maintenance. It can not only replace manual forging, reduce labor intensity of workers, but also improve production efficiency.

The air hammer is characterized by its fast strike.It USES falling energy to forge metal.The greater the weight of the falling portion, the greater the impact energy.When the weight of the falling part is fixed, the impact energy increases significantly with the increase of the strike speed.Air hammer can be free forging, such as drawing, upsetting, punching, bending, torsion and other processes, but also can be forging.

Air hammer is composed of frame, transmission mechanism, compression cylinder and working cylinder, compression piston, falling part, hammer body, control mechanism, valve mechanism and anvil.

Driven by an electric motor, the air hammer drives the crankshaft connecting rod mechanism to rotate through a reduction mechanism, making the compression piston make up and down reciprocating motion in the compression cylinder.When the compression piston downward, the air in the lower part of the compression cylinder is compressed and enters the lower part of the working cylinder through the down-rotation valve. At the same time, the air in the upper part of the working cylinder enters the upper part of the compression cylinder through the up-rotation valve and ACTS on the air pressure in the lower part of the working piston to make the falling part move upward.When the piston is compressed upwards, the air flows in the opposite direction. The pressure of the air acting on the working piston and the weight of the piston cause the falling part to move downward, forging the metal billet on the lower anvil.By using handle or foot lever to operate up and down swing valve, the hammer head can realize different actions such as empty stroke, suspension, compression and continuous light and light strike.
Zaozhuang make machinery co., ltd has a variety of models of air hammer c41-16, c41-25, c41-50, c41-55 and other models to meet the needs of different customers.
