Research Of Process And Equipment For Three Roller Plate Coiling Of Level Adjust Below

Roll Machine can bend metal plate to a special shape, such as column, cone, camber and so on, which is widely applied to boiler manufacture, shipbuilding, chemical industry and machine manufacture. In Tianjin Tie Chang Corporation, Roll Machine is needed to maintain the steel manufacture and supply steel duct for building The Second Steel Plant. For this purpose, a class of Roll Machine has been developed in order to improve the productivity, decrease the work intensity and content the demand of the factory for plate coiling.Based on the principle of metal plate mold capability bend distortion, the athletics and motivity of plate coiling has been analyzed. The geometry parameter, mechanics parameter and technics parameter was optimized on level adjust below three rollers Rolling Machine. The mathematical model of plate coiling was built and production process was established. Using the hydraulic pressure driving protocol. The analyses of the basic loop and hydraulic pressure system have been performed. According to the demand of the produce, the whole project of Rolling Machine was designed. The structure and technics parameter of 20×2500 Rolling Machine was computed and confirme.The characteristic of level adjust below three rollers Rolling Machine in this investigation is as follows. Using the type of level adjust, the end can be bended without turn around and the whole process of plate coiling including entering,center adjusting,pre-bending,coiling,cylinder proofread can be completed continuously; due to whole hydraulic pressure driving protocol, the structure was simplified, and speed and pressure was easily controlled in the process of plate coiling;The setup of the center adjusting and the equip of supporting, the precise and quality of plate coiling was improved; owing to the simplified structure, the operation and maintenance is easy to carried out.
