Introduction of C92K Series CNC Fully Hydraulic Die Forging Hammer

Anyang's CNC forging hammers are widely applied for varieties and mass production in automobile,motorcycle,construction machine,hydraulic fittings,instrument hardware,construment hardware,daily use hardware,surgical instruments,kitchen hardware,farm tools,knives and other metal precision die forging industry. In addition to a wide range of high-density shaped parts applied in the aerospace industry,shich is the core of automated precision forging production line equipment.

 Advanced Technology of Closed Die Drop Forging Hammer

• 1.The hit control system is adopted precision control system, which makes the high precision of hit energy control.

• 
  

2.The operation for the tup slow up and slow down is very convenient, change die is more safe, convenient and fast.Due to the hydraulic system is set special release oil valve, so it can realize the tup slow up and slow down at any moment without release the pressure in the hydraulic system, which makes the installation and adjustment of dies are very safe,convenient and fast.

3.Special connecting structure of large valve block and oil tank, making the large valve block to maximize the maintenance-free.

4.The buffer structure of tup is adopted outreach structure, which overcomes the problems of the unreliable inside welding structure.

5.The accumulator is adopted low level installation, reduced the height of the machine.

6.The safety of hit valve system is fully guaranteed, Due to both of the two control ends of hit valve are equipped with buffer device, so such dangerous case will not happen for the hit valve core collides the valve cover leads to the bolt crack caused by the control system has problems.

7.Reliable hammer rod sealing.

8.Reliable safety device of lower sealing.

Performance  Characteristics of Closed Die Drop Forging Hammer

1.Hit energy and working procedures are intelligent controlled. Hit energy are precisionly digital controlled; Working procedures are programmable for different forging pieces through touch screeen, the working procedures can be saved up in the system and ready to use on requirements.

2.High precision forgings, The hammer body is adopted "U" type whole piece castings,large rigidity, coupled with special  "X" type guide rail, which ensures the space between tup and guide rail controlled within 0.22mm, thus making it possible for precision closed die forgings and providing the conditions for all kinds of forgings at minimum machining in future.

3.High hit frequency: Due to short stroke of this hammer, and lower chamber always connects with the accumulator, the system pressure is high, so the hit frequency is more than doubled than the conventional electro hydraulic die forging hammer,thus improves the production efficiency.

4.Increase the working life of machine and die: The extra hit energy occurs in forging process is not only largely consumed and wasted and occurs noises, but also greatly affects the life of machine and die due to the absorption of extra energy. CNC fully hydraulic die forging hammer can precisonly control the hit energy, greatly increase the working life of machine and die, well controlls the noise too.

5.High material utilization rate.

6.Stable performance and equality of forging quality,

7.Ejection system.

8.Easy to realize automated production line.

CNC Hammer Converted from  Conventional Die Forging Hammer

Convert the original steam-air hammer and electro hydraulic forging hammer to be CNC fully hydraulic die forging hammer using the advanced numerical control technology.

1.The Convertion Principle:

The hydraulic principle is almost same with the brand new CNC fully hydraulic die forging hammer ,so far the speciality of steam-air hammer or electro hammer(long stroke ,small guide rail clearance, small size of connecting plate at top of the arms,and diffculty in installing the numerica control power head),the  convertion in design has following characteristics compared with brand new CNC fully hydraulic die forging hammer:

(1)For the convertion of 1T and 2T old hammers, it is adopted integrated big oil tank setting on the top of the hammer, and changed by big connecting plate; For the convertion of old hammers above 3T. It is adopted the main and auxiliary oil tanks setting(i.e. the main oil tank is set on the top of the original connecting plate, and the two auxiliary oil tanks are set on the two sides of power head supported by the steel frame), the connections between the main and auxiliary oil tanks are flexible structure.

(2)Meanwhile change the new tup with "X" type guide structure, the guide rails of the hammer body are changed accordingly, thus improve the ability of inclined loading and increase the precision of forgings.

(3)Due to the long stroke of old hammer, thus we design a top die seat on the tup, so decrease teh stroke as well as protect the coattail of tup.

(4)The ejection system and new die seat can be designed adn supplied as per customers requirements.

2.The performance of converted hammers are almost same with that of  brand new CNC fully hydraulic die forging hammers which not only overcomes the disadvantages of old hammers, but also upgrades the hammer to a higher status.
