Abstract: Recently, Anyang Forging Press Company according to the characteristics of the production process for pneumatic forging hammer forge steel balls, successfully developed  special air hammers to produce grinding steel balls, the special power hammers forge steel has some advantages such as less investment, quickly organize production, large steel balls production range and so on.

Air forging hammers forge grinding steel balls is a traditional forging production process, using an air hammer forging the raw materials to the required amount of deformation, increase the forging ratio, so that the internal structure of steel ball is more dense, improves the toughness and density, improves the wear resistance, reduce breakage, the forged steel ball retains excellent stability under various harsh environments.

 1. Special power forging hammer introduction:

Special air hammer forged grinding steel ball with features of less investment, quickly organize production, large-scale production ball range etc, rolled round steel bar and square steel can be used as raw material , forging grinding steel balls are widely used in mining, cement, coal grinding balls and other fields.

Pneumatic forging hammer is a kind of free forging machine, with its own two cylinders: compression cylinder (rear cylinders) compresses air, feed into the working cylinder (front cylinder) through the dispensing valve, and push the tup(ram) up and down together with the hammer rod action. The dimension of air hammer is small, low noise, reasonable structure, easy to operate. Applicable to all kinds of open die forging: such as drawing, upsetting, punching, shearing, welding forging, twisting, bending etc., it can be carried out using a variety of pad mold for open die forging (die forging).

II. Technical characteristics of special air hammers forge grinding steel balls:

Anyang Forging Press Company according to the characteristics of the production process for pneumatic forging hammer forge steel balls successfully developed special air hammers to produce grinding steel balls. Compared with the conventional C41 series air hammer, the power forging hammer specially for producing steel ball has following Features:

1. The thickness of the air forging hammer cylinder wall is thicker, reinforced airframe structural strength.

2. The length of pneumatic hammer and hammer guide cylinder have be prolonged, enhanced guiding; large outer diameter to increase the guiding to strengthen the stability of the lead and body connection.

3. Remove the guide surface of air hammer, in the process of forging steel ball , according to the forces of reaction force impact on forging die, the hammer rod is free to rotate, decreases the reaction on the hammer rod and hammer body, prolong the life of pneumatic forging hammer.

4.The lower part of the air hammer cylinder increase hot mounted ring to pre stress hammer body, to ensure the stability of hammer body and lead while forging steel ball.

5. The hammer rod of lead anti-leak ring is changed to four circle arc structure, improve sealing performance.

6. Steel ball die (mold) is using sets of mold structure, namely the upper and lower anvils are mold frame, set the ball in the mold box mold, semi-circular wedge connection using a mold, just replace the ball mold while produce different diameter steel balls, without replacement upper and lower anvil, realize the aim to reduce the investment of steel ball dies and quick-change die purposes.

IV. Advantages of Anyang Forging Press Company’s Pneumatic Forging Hammer:

1. Anyang Forging Press Company’s C41 series pneumatic hammer was awarded national "Quality Silver" (the highest quality award in Chinese pneumatic forging hammer industry).

2. Anyang Forging Press Company drafted the existing national standards of air hammer.

3. Anyang Forging Press Company is the only one manufacturer of pneumatic forging hammer issued "quality assurance statement” through the “China Industry News " at home and abroad, won the trust of users.

4. Anyang Forging Press Company’s pneumatic forging hammer was awarded “Origin Certificate” by China government to protect the excellent quality products.

5. Anyang Forging Press Company’s “Golden Anvil” air forging hammer was awarded “Henan Province Famous Brand”.

6. Anyang Forging Press Company self-developed China's first also the world's first C41-2000kg air hammer in 2006.

Anyang Forging Press Company is the only manufacturer that continuously producing pneumatic forging hammer for 60 years in China; also it is the only manufacturer whose pneumatic hammer was awarded Chinese highest quality award in China. Anyang Forging Press Company was the only manufacturer that committed to draft national manufacturing standard of power forging hammer, which is still in executed. The products is from C41-9 to C41-2000, Anyang Forging Press Company not only produce two-pieces pneumatic forging hammer, buy also produce one-piece smaller power forging hammer(below 75kg). Which is usually used by blacksmith for the art forging. Anyang Forging Press Company’s steel iron air forging hammer has self air compressor structure, it can be put into run after connect with the power, don’t need to be equipped with other device. The quality is reliable, the performance is stable. Anyang Forging Press Company’s forging equipments are popular in the world, till now, the forging machines has exported to more than 60 countries. Anyang Forging Press Company has passed ISO9001:2008 Quality Certificate, and the power forging hammer has got CE and PEOP Certificate.
