       Description:
      Conversion of hydra-pneumatic hammer, the existing hydraulic driving system, pipeline system, cooling system, electric control system, operation system and striking system will be improved and exchanging a new fully hydraulic driving system. The technological parameter is same as before after conversion. For existing hydra-pneumatic die forging hammer, we suggest to convert to PLC fully hydraulic die forging hammer. But if considering saving cost, you can convert to follow-up control fully hydraulic die forging hammer. This kind of conversion can make ram stop in any position during striking, and with good flexibility, so it is very good for some forgings with high requirement for rolling and drawing. But the constant is not better than PLC fully hydraulic die forging hammer, and depends more on workers skill.


      After conversion to follow-up control fully hydraulic open die forging hammer,

       its features:

      1) single bar operation can realize ram slow up, slow down, striking, return, fast return, stop in any position, continuous striking with different stroke and frequency, and its operation is simple and easy;
      2) fine structure, there is not inertial empty in hydraulic cylinder, its action is coherent;
      3) fast oil in mouse and fast oil out mouse are both control by servo, so it can avoid wrong action like hydra-pneumatic hammer, and safety;
      4) Main valve is with features of slide valve moving and taper valve sealing, to improve controlling and sealing of valves mouse opening and closing, to reduce system inner leakage and heating;
      5) Main control valves is servo valve designed by CFM, with wide application, and can meet requirement of 1-20 ton die forging hammer and 1-10 ton open die forging hammer;
      6) System oil consumption can be monitored; when system need more oil consumption, many pumps will with load; when system need few oil consumption, some pumps will with load, other pumps will with unloading. That can reduce pump and unloading valve unloading frequency and to reduce hydraulic punching to improve their life(patent);
      7) System is designed with over pressure and losing pressure protection. When main oil tube or piston rod is broken, system will close main oil channel and turn off the main motor at once to improve system safety.
