It uses one-piece U-frame casting steel hammer body, with max. striking energy from 16kJ to 250kJ. That frame is wide application and standard one. Hammer body is cast as one piece to avoid columns and anvil connecting, reduce separated hammer body contacting surface wear, improve body strength, and make this hammer afford off center forging force. 

Its guiding is using the steel X-shape guide rails fixed in the hammer body inner face by bolts, with three inserted locating face to avoid bolts receive force. Imported locking washer is used to avoid bolts lose. Extending line of contacting surface of guide rails and ram crosses on the ram center, which cannot effect guide clearance due to heating, and clearance between ram and guide rails can be adjusted to be small to assure die matching. And this guide rails lubrication is automatic and once forging is stop, lubrication will be stop. 

Its striking system is with big ram structure, which can make sure striking energy when striking speed is down. And longer ram guiding can improve hammer working accuracy. 

Its control system can make sure striking energy controlled and program striking realized, avoid vibration and noise arising from surplus energy. Program automatic control system can control each striking energy and steps according to requirement, which make striking system vibration and noise reduce more, lower requirement for operator, get stable forging accuracy, improve hammer running reliability and die life. Striking program is easy to input, no need skilled computer engineer, even semi-skilled worker is OK. There is malfunction display window on this control system. Once problem, it will be easy and quick to find malfunction reason through this window, and then deal with it at once to short maintenance time.

New cylinder-valve CNC Fully Hydrulic Die Forging Hammer with independent intellectual property rights independently developed, designed and produced by CFM has been successfully developed. The cylinder-valve integration technology is to install the drum structure valve(striking valve) on the top of work cylinder co-axially realizing cylinder-valve integration.

Advantages:

1.Improve striking energy control accuracy

The drum structure taper valve with lighter valve core and bigger valve port through diameter, quicker dynamic response compared with existing taper valve and slide valve. It is good for big tonnage CNC fully hydraulic die forging hammer accuracy control of high frequency, high speed movement, avoid striking energy out of control caused by two valve linkage.

2.Realize no pipe connection

Install special drum structure taper valve on the top of work cylinder co-axially to realize cylinder-valve integration and carry out no pipe connection between striking valve and work cylinder. Compared with existing horizontal type striking valve design, it is with shorter oil circuit, higher hydraulic transmission efficiency, faster response speed.

3.Vertical taper valve avoid single side wear

Valve core side will not be affected by self gravity, which avoid single side wear and hydraulic jam caused by taper valve or slide valve self gravity. Its service life is much longer than horizontal type striking valve.

4.More reliable sealing performance

The drum type taper valve seals main oil circuit through valve port tapered surface. Compared with slide valve, taper valve is with no leakage. Taper valve with good anti-pollution performance, sealing performance will not be affected by using time and hydraulic oil temperature.

5.Special drum type cylinder realize return dynamic energy absorbing

When ram returns, the piston rod enters into taper valve inner hole, work cylinder oil port is plugged. The hydraulic oil in upper cylinder of piston rod is closed and generates oil pressure under the return dynamic energy. The pressure acts on drum type taper valve, makes the taper valve open slightly, then the return dynamic energy turns into hydraulic oil pressure energy. The opening size of the taper valve is servo controlled by oil pressure. The hydraulic oil flows into accumulator storage for next striking. After the ram dynamic energy release, the drum type taper valve will be closed automatically.
