Lost foam internal spline fork head casting process design method based on computer assistance

Abstract

The invention provides a lost foam internal spline fork head casting process design method based on computer assistance. The lost foam internal spline fork head casting process design method comprises the processes of pouring system design, casting simulation analysis, pouring gate structure optimization, process parameter optimization analysis, production inspection and the like. A designer designs a gate and riser system according to the structure of an internal spline fork head, a casting three-dimensional model and a finite element model are established, boundary conditions and initial conditions are input to carry out casting numerical simulation analysis, and a simulation result is obtained for the designer to carry out structure and process parameter optimization. According to the method, a casting process of coupling fork heads of different structures can be designed, casting defects can be effectively predicted, and the development cost and the development period are saved to a certain extent.

Description

technical field [0001] The invention belongs to the field of casting technology and lost foam casting technology, and in particular relates to a method for designing a casting process of a lost foam internal spline yoke based on computer aids. Background technique [0002] As a kind of coupling, the internal spline yoke of the lost foam is mainly used in the rolling mill production line. It is the core accessory of the rolling and forging equipment, and the production environment is relatively harsh. Under the action of alternating cycle external force, it is easy to cause stress concentration, and it is a part that is more likely to fail. Therefore, core components such as coupling yokes need to be checked and replaced regularly to prevent major equipment accidents caused by sudden breakage of coupling yokes, resulting in long-term production stoppages and serious economic losses. In recent years, with the continuous growth of the machinery industry, the average annual com...

Problems solved by technology

The test method and empirical method have good results for castings of the same material and similar structure, but for castings of different materials and different structures, the trial and error method and empirical method are less effective, and often require a lot of manpower, material resources and resources. Time, and many trials to resolve various defects in castings
