ST-40 Blacksmith Power Hammer

ST-40 Blacksmith power hammer is designed for the forging of hot metal, Forging material should be full heated before forging, or it will greatly reduce the life of the hammer. The blacksmith air hammer has two cylinders: the compression cylinder and the working cylinder, by compressing the air and send it to the working cylinder, and pushes the hammer rod together with the hammer to hammer up and down. 
The quality problem of the blacksmith air hammer seriously affects the normal operation of the forging industry and brings economic and human losses. After years of hard work, our company's technology research and development team has successfully tested in several forging factories. After years of testing and use, the new product is now available, and customers are welcome to contact us.


Technical Advantages

Pedal-type control, high-efficiency forging

ST-40 air hammer is driven by a motor to make the compressed air drive the beating action, and the pedal-type control striking force is a high-efficiency forging device.

High quality casting bed frame, good performance in decades year

ST-40 air hammer bed frame is made of high quality castings, and the surface of the casting is heat treated for durability and no deformation. When customers purchase a single air hammer, often after decades of use, the equipment still maintains good performance.

Integrated structure of hammer rod and the working piston

The falling part of ST-40 air hammer is composed of a working piston, a hammer rod and an upper anvil. The hammer rod and the working piston are integrated. To make the weight conform to the technical specifications, the hollow rod can be made into a hollow piece, and the connection between the hammer rod and the hammer head can be made. It is connected by a dovetail groove and a wedge iron. The design of this structure is very clever, allowing users to flexibly match the workpiece according to the requirements of the process.

Stable forging, striking without vibrations

The mass of the air hammer anvil is 12-15 times the mass of the falling part, which can increase the stability of forging. The anvil is mounted on a sturdy reinforced concrete foundation with padding in order to eliminate vibrations from hammering.

Jiahua Machinery is a professional manufacturer of blacksmith power hammer in Anyang. ST serie blacksmith power hammers are sold at home and abroad. ST-40 means the weight of its hammer head is 40kg, this is one of our main product which is popular both in small and normal forging workshop.
The small blacksmith power hammer is mainly composed of machine body, transmission mechanism, compression cylinder and working cylinder, compression piston, falling part, gas distribution mechanism, and steel base.

1. The machine body is the main body of the blacksmith power hammer. The transmission body, the working mechanism and the operating mechanism are mounted on the fuselage, and these mechanisms are compactly combined into one unit on the frame.
2. transmission mechanism. The transmission mechanism includes a pulley, a crankshaft, and a connecting rod system. It converts the rotational motion of the motor into a reciprocating motion of the compression piston.
3. compression cylinder and working cylinder. The upper and lower parts of the compression cylinder and the working cylinder are connected with the up-down rotary valve, and the working piston is driven up and down by compressed air generated by the up-down movement of the compressed piston.
4. falling part. The falling part is composed of a working piston, a hammer rod and an upper anvil, and the hammer rod and the working piston are integrated, and the hollow piece is required to make the weight conform to the technical specifications. The connection between the hammer rod and the hammer is connected by a dovetail groove and a wedge iron.
5. gas distribution mechanism. The gas distribution mechanism is composed of an upper valve, a lower valve, an operating handle or a pedal lever, and the gas distribution mechanism is used to control various actions.
steel base. Due to the small size of the small blacksmith power hammer, the overall design of the anvil-free body is adopted. Therefore, the role of the steel base is to raise the lower anvil surface of the hammer to a suitable height so that the forger can work comfortably and increase the weight of the anvil portion to eliminate the vibration generated during hammering.
