2.Products
2.1 C88KCNC Fully Hydraulic Die Forging Hammer
2.1.2 Description
C88K series CNC fully hydraulic die forging hammer use one casting U-frame hammer body. It is with
max. striking energy from 16kJ to 160kJ. The U- frame has been widely used and is a standard one. The
U-frame structure avoids connection between hammer frame and base, which reduce separated hammer body
contacting surface wear, improve body strength and eccentric load capacity.
The guiding system use X-shape steel guide rails fixed on the hammer body inner face by bolts. It is with
three inserted locating face to avoid bolts receive force. Imported locking washers are used to avoid bolts loose.
Extending line of contacting surface of guide rails and ram crosses on the ram center, which ensure the guide
accuracywhen heating expansion. And clearance between ram and guide rails can be adjusted to be very small
to assure die location. And this guide rails lubrication is automatic and once forging is stop, lubrication will be
stop.

The striking system is with big ram structure, which ensure the striking energy do not affected by striking
speed fast and slow And long ram guiding can improve hammer working accuracy.
The control system make sure striking energy can be set through operation interface, avoid vibration and
noise arising from surplus energy. Program automatic control system control each striking step and energy
according to requirements, which reduce vibration and noise greatly. It reduce the requirement for operator,
get stable forging accuracy, improve hammer running reliability and die service life. Striking program is easy
to input, no need skilled computer engineers, even semi-skilled worker is OK. There is malfunction display
window on this control system. Once problem occurs, it is easy and quick to find malfunction reason through
the window and then deal with it at once to short maintenance time.
Special designed die automatic lubrication device, blanks convey system, ejector and scale removing
system are optional. They can be linked to hammer through program and realize die lubrication, locating,
timing, quantity control, to improve productivity and reduce labor intensity.
2.1.3 Main Advantages
 Touch screen man-machine interface, numerical input, fault automatic diagnosis and alarm display
in Chinese and English.
 Striking energy and steps can be set numerically,which can reduce the surplus striking energy, lower
the noise, prolong die lifetime.
 U-frame one-piece casting steel and radial wide guide rails make ram with high guiding accuracy.
 Three inserted locating faces for the guide rail, special design preventing bolts loosing.
 High integrated hydraulic control system, without any pipe connection.
 Special design for system safety protection, making sure the safety use of the forging hammer.
 Imported accumulator assembled on the hydraulic valve block directly, improved the transmission
efficiency and easier to maintain.
 Advanced taper valve design, fast response, good sealing and not easy to generate inner leakage

 Swaying compound oil cylinder and elastic flexible hammer rod, high and low pressure double
anti-leakage design, which greatly improved the reliability of the forging hammer.
 Slow up and down in the case of releasing hydraulic system pressure to make die changing safety.
 Ram buffer is inner hydraulic buffer, to make sure ram movement safety and coordination;
