CD88K CNC Fully Hydraulic Counterblow Hammer drive system adopts full hydraulic power drive technology, adopts advanced cylinder valve integrated cone valve control technology, composite cylinder transmission technology, dual leakage technology and hydraulic integration technology, the system structure is simple, the key hydraulic components and seals are imported.

Its strike programming is simple, do not need skilled computer personnel, even semi-training adjustment workers can be adjusted. When working, the control system can realize the online detection and digital display of oil temperature, oil pressure, cleanliness and position. Once there is an error, the fault light will shine and the display will show the location of the fault and the nature of the fault. The latest design of optional remote monitoring system for customers can reduce the time and cost of maintenance engineers to the site, save a lot of human and material costs, at the same time, but also can provide customers with faster service, reduce the loss of customer shutdown.

Energy saving, low investment and operating costs. Fully hydraulic drive transmission efficiency is high, its energy consumption is about 1/4 of the air driven forging hammer. Its energy saving effect is also reflected in the precise control of strike energy and the absorption and utilization of return kinetic energy. The effective control of heavy hammer strike energy can avoid the strike of excess energy, and effectively improve the service life of the mold and the reliability of the forging hammer. 

The upper and lower ram suspended counterstrike movement has a small vibration impact on the equipment foundation and surrounding buildings, which can greatly reduce the total cost of equipment investment and workshop cost. 

The large-capacity energy storage system can greatly reduce the installed power of the whole machine, and the hierarchical control of the main motor can reduce the starting times of the main motor. 

Highly integrated, compact hydraulic power system, can reduce hydraulic leakage and hydraulic oil. The linkage cylinder adopts an independent accumulator hydraulic system. The hydraulic system is equipped with a control valve that releases some high temperature hydraulic oil after the temperature rise and participate in the circulation, so as to avoid the frequent replacement of the linkage cylinder seal due to the high oil temperature, reduce the maintenance cost and improve the work efficiency. 

The upper and lower ram have good guidance and are not easy to mistake the mold. Due to the good guidance, the lateral force of the mold is small and the bonding tendency of the forging is small, at the same time, the forging hammer speed is fast and the mold contact time is short, which is conducive to the forging of the parts and improving the life of the mold.

1. Characteristics and advancement

1.1 Highly active 
The unique fully hydraulic power drive technology makes the hydraulic hammer can obtain huge kinetic energy in a very short stroke, that is, short stroke high speed forging, high frequency continuous forging become a reality.  At the same time, it can be linked with the additional mold automatic lubrication system, top material system, heavy-load robot, spray device, etc., which can greatly reduce the labor intensity of the operator and improve the work efficiency.

1.2 High safety 
The power system is integrated and there is no main system hydraulic pump station on the ground. The high pressure oil path is located in the forged cylinder block and valve body to ensure safety. The power head steel structure itself is not used as the pressure oil conduction part of the hydraulic drive system, and all the welds do not bear the hydraulic pressure, to completely avoid the hydraulic oil leakage caused by the weld rupture, to ensure safety. Safety support and electrical interlock design to ensure the safety of the mold space. Remote operation can be realized, and strike preparation switch shall be set on the foot switch to ensure the safety of strike operation, and to ensure safety through electrical and hydraulic interlocking control and energy limit. Double control of the safety valve and the pressure sensor to ensure that the forged hammer works safely within the specified pressure range. Unique return pressure buffer design ensures that the hammer head return trip has no mechanical impact and the hammer head action is safe and coordinated.

1.3 High-accuracy
Using the mold forming, the upper and lower hammer head guidance is good, not easy to wrong mold, can improve the precision of forging forming, reduce material consumption;

1.4 Automation and intelligence 
The fully hydraulic die forging hammer can realize the digital control of the forging hammer. The strike energy and strike step sequence can be set through the man-machine interface, and completely avoid the forging accuracy deviation caused by the skills of the operator. The control system has an interface that can be linked with the robot, spray device, lubrication device and top material device to achieve automation.

1.5 Low vibration 
The forging hammer adopts spring damping vibration separator, and the vibration isolation efficiency can reach 85%. The forging hammer has almost no impact on the surrounding equipment and building facilities.

1.6Stable product quality 
The full hydraulic die forging hammer is controlled by electronic program through digital input, and the forging operation is consistent no matter who steps the plate. The process for a special part can be programmed and can be stored digital. When the same part is forged later, only the part code must be called out, and the forged hammer can be produced immediately.

1.7 Low noise 
Forging hammer noise is inevitable, but it can be reduced. Full hydraulic die forging hammer can accurately control the strike energy, especially the control of heavy hammer strike energy. Each strike energy can be regulated, and can be controlled through digital input and the choice of foot switch. When the excess strike energy is controlled, the noise will be reduced accordingly.

1.8 Simple maintenance and operation 
The hammer of fully hydraulic die forging is characterized by simple design, and can use the standard general hydraulic pilot valve to realize oil filling, oil discharge, adjustment, strike, knock hammer, pressure hammer and other basic actions. It can monitor the cleanliness, temperature and pressure of the hydraulic oil through sensors. Once the phenomenon that does not meet the operation conditions of the system occurs, the automatic alarm, and realize the automatic diagnosis and self-protection of faults, and timely stop the hammer or even stop. The auxiliary facilities that may involve safety should also be monitored as carefully as possible for the main engine, if the host does not meet the requirements. In order to facilitate the user can better and faster to do the repair, maintenance work, all hydraulic hammer with common fault Chinese display window, once appear abnormal, through the fault display window that can soon find the cause of the fault, also can realize through remote monitoring fault remote diagnosis, in order to be quickly processing, shorten the maintenance time.

1.9 Extensive adaptability 
Program control full hydraulic strike hammer can be adapted to single or mass production, with super control flexibility.

It is mainly used for medium and small batch production of large and super large non-ferrous metals, such as superalloy steel, stainless steel, special steel, carbon steel large forgings; hard-forming parts and thin parts; large valve body, lifting hook, heavy load wheel, aircraft landing gear, leaf gear; high strength structural parts of nuclear power and ship large machinery, etc.
