With the development of China’s urbanization and industrialization process, the consumption of steel is bigger and bigger. China’s steel industry needs to make it happen in structural adjustment and resource conservation, the realization of China’s steel industry from large to strong changes. At the same time due to fierce competition in the domestic steel production increased and the international steel market, more and more steel companies began to focus on endless rolling technology. The traditional joining technology of endless rolling for intermediate billet has a lot of problems, such as require long joining time and connecting device is quite complex and huge in size, the inevitable unstable operation at head and tail end leads to yield loss. Hence, a new joining device for intermediate billet of endless rolling must be put forward.Firstly, through the endless rolling technology analysis, choose the shortest joining time among billet connection technology- solid middle blank laminated France. Design a device can be achieved intermediate billet connections and references are given basic dimensions, determined the reciprocal kinematic relationship of each parts and the structure design of the joining device for intermediate billet. All aspects of ability parameter were worked out for joining device. The selection standard parts were performed verification calculation to ensure the reliability of joining device.Secondly, used the three-dimensional modeling software Solidorks to entity modeling for the fast shear extrusion joining device, and carried on the assembly under the assembly mode. Then import assembly into the ANSYS Workbench software of finite element analysis for modal analysis, analysis of the influence of each order modal, in order to avoid resonate for joining device.Finally, import assembly model into the Adams software of automatic dynamic analysis of mechanical systems for kinematics analysis, and listed the law of motion for the main components, horizontal velocity and a trail about its movements of upper and lower cutter, and compare the results with theoretical analysis. Then conduct analysis of dynamics and rigid-flexible coupling to joining device assembly model, check the maincomponents of the stress distribution and force status, then judge the main components to meet production needs. |
