Design And Structure Research Of Clamp On New Rolling Process For Crankshaft Mechanism

In the crankshaft production the rolling process for strengthen the crankshaft would increase obviously its fatigue life-span,therefore the crank fillet rolling the craft,the equipment and its correlation technology has become one of essential technologies in the current automobile industry. This paper mainly research several rolling organizations of machines of crank fillet rolling both at home and abroad,and has done the following aspects of work(1) Using the mechanism theory analyzes several rolling organizationg of domestic machines, compared to foreign advanced machine, points out that the deficiency of one of the domestic crankshaft rolling machine and its improving direction. In its mechanism design basis, combining with the design concept of Germany import machine,designing the new rolling organization of new mechine.(2) Virtual design and simulation analysis of the new rolling organization were made on the platform of UGThrough the simulation analysis of motion process of several small organizations of the new rolling organization such as loosen,clamping,swing repeatedly,and rolling movement of rolling clamp,verifying the feasibility of new organization,and optimizing its structure,and realizing the optimization target of the calmp mouth Angle more large,mechanism design more simple and compact,several calmps synchronous work etc.(3)Static analysis of virtual rolling arm were made on the platform of ANSYS,getting the stress distribution of the rolling arm from ANSYS analysis,and then put forward the improving structure scheme of the rolling arm,realized its lightweight target.In addition,the paper also carried on the discussion and the forecast to the machining stability of desinged organization,the electric control of machine and the expert alignment system which is need in this kind of machine.Because the passenger vehicle crank has the very big demand in our country,so independently design the manufacture independently the highly effective trundle equipment will be able to bring the very high economic value.After doing this paper’s research,it can propose certain rationale for designing and manufacturing the new crankshaft rolling equipment.
