Punching Die Design And Numerical Simulation Of The Motor Vehicle Window Glass Lifter Shell

Modern mould industry is known for never declining. Only as far as automobile industry is concerned, thousands of moulds which value more than one hundred million RMB are needed in only one type of automobile. However, about 80% of the moulds will need to be replaced when the type of the automobile is going to be changed. In the total value of output of mould industry impact extrusion occupies 50% or so. People begin to realize the great importance of mould in manufacturing and perceive that the technical standard of mould has been regarded as a symbol that indicates the level of the manufacturing in a nation. Further more, mould determines the quality of the products, benefit and the capability of new products exploiting to a great extent.。This paper mainly focuses on modeling and assembling the whole set moulds which are used to produce the sheathing of automobile glass riser by using the powerful function of UG in respect of modeling. Speedy conceptual design can be conducted by substantiality modeling system and their requirements and the programming restricts will be combined by the mathematic relation among different components in conceptual design. Basing on features, substantiality modeling and editing capacity help the designers changing and renewing substantiality by way of editing the dimension of substantiality features directly or other geometric editing and constructing techniques. UG and the ANSYS interface issues discussed. of professional CAD software modeling and simulation software to integrate very well. The designers can also establish automobile impacting extrusion finite element mould using the great function in respect of data imitating of ANSYS finite element analyzing software, and the strength, rigidity, stress-strain and other calculating tasks can be conducted at the mean time. Besides, effective exploring on the building of boundary condition can be executed, so as to avoid many singular points, to optimize the construction and improve the quality of the product.For the sake of optimizing design plan, CAD and CAE can be used simultaneously in designing, calculating analysis and designing can be conducted at the same time. Therefore, the fact of analysis after the problems of the products be found has been changed that the problems can be controlled in advance in the process of designing and exploiting so that the quality of the product can be ensured at the rock bottom. On the basis of these facts, designing and manufacturing can be connected more tightly, and the production efficiency can be improved accordingly, so that the basis of intelligent manufacture in the future has been established.
