This cold rolling machine adopts the double working positions of rolling and sizing, and organically combines the control system, the hydraulic system and the mechanical structure through symmetrical structure, reliable shafting, suitable hydraulic proportional loading mode, fast and reliable magneto-electric detection system and stable electric control system. The cold rolling machine layout is right feeding and left discharging.
The mechanical structure of the cold rolling machine is of high-rigidity design, and the symmetrically arranged shafting support is the basic guarantee. The application of active measurement technology makes the machining process under full tracking and control. Besides, the rounding device makes the geometry of the work piece in the rolling process good.
The cold rolling machine has two working patterns, one is simultaneously coll rolling and plastic motion, the other is cold rolling or plastic motion respectively. The cold rolling machine uses PLC control system. The novel researching PCR type of open cold rolling machine applies combinational modal mechanism, using computer for realtime displaying and controlling rolling process, adopting the new technologies of active measurement and proportional servo system. The PRC type has not only the advantage of international same kind type but also the unique features, having high adaptive avility to the blanks, easily and rapidly to operating and regulating.
