The Analysis And Research Of Casting Process Of Valve Body Based On CAE

Foundry is one of the most important manufacturing means for the blanks of the mechanical products, and it plays a great role in the country's economy. With the forming of the worldwide market and the growing of the market economy, the foundry plants have to face the more and more severe contention and challenge. The traditional productive model and casting design is not able to meet the demands of the markets. The foundry plants would have to change their traditional manufacturing means and introduce new technologies and new methods.The technology for simulation and optimization of the solidification processes of the castings, so-called the casting CAD/CAE technology, displays the whole process of the casting and the formation of the models and the defects visually in the computer. By using the technology of casting CAD/CAE, the uncertainty of the plane of the casting proceeding has entirely disappeared, and the quality of the castings. Moreover, it shortens the period of the invention of new products and lowers the costs. All above points help to enhance the productive level of the foundry plants.It utilizes design software Pro/E to create three-dimensional modeling for casting steel valve body, uses MAGMAsoft has good appraisal functions to casting technology optimization design, and put up CAD/CAE research on valve body pieces of the whole course. the technology succeeds in using it to go on the filling and solidification numerical simulation of castings, reflects actual state of castings accurately, predicts defect that may appears during filling and solidification process then ascertains the position of the defect. Putting riser close to valve castings' hot-spot position, it makes castings solidify orderly, it can improve hot-spot state effectively, can achieve the goal of dispelling and controlling the defect, proves that the casting technology of utilizing numerical simulation to optimize is effective and feasible. And valve body piece is produced in fact, casting quality can up to it is required to.In a word, applying CAD/CAE technology to cast industry can study the whole course of cast production with speediness, nicety, low cost. To adopt this technology for changing the blindness completely while making the casting technology scheme, guaranteeing casting quality, raising productivity of casting and even promoting cast technological progress has very important function.
