Abstract: In view of the problems existing in the traditional cooling support roller "roller ring-shaft-bearing cover" processing line, such as wide processing area distribution, long processing cycle and many operators, TCDRI independently developed and designed a flexible digital processing line for cooling support roller device. The production line is mainly composed of CNC horizontal lathe, vertical machining center, quenching machine, industrial robot, etc., which can realize multi-process automatic processing of work piece. The robot can quickly change the fixture according to different kinds of work piece, and the soft floating control function is introduced to realize the elastic movement and follow-up movement of the robot. The frequency of detection and alarm caused by the adhesion of iron filings can be reduced by the combination of water vapor cleaning and iron chip cleaning. The digital integrated control system can realize the real-time acquisition of equipment status and measurement data, and connect with PIMS system. The application practice shows that the flexible processing line greatly improves the production efficiency and product quality of the cooling support roller, reduces the manpower operation demand, and can bring significant economic benefits to the enterprise.
