Abstract


Multi-point forming is a flexible manufacturing technology, the basic body composed of flexible multi-point die arranged in a series of rules , a machine with the idea . Multi-point precision molding technology forming the products , to improve the degree of production automation , to solve the problem of multi- type small batch processing . Therefore , the use of this technology to the production of automobile cover , and will help to increase the rate of replacement of automotive products . In this paper, the hood , for example , the first study the basic principles of multi-point forming forming characteristics analysis of multi-point forming the test specimen forming defects factors to select a reasonable forming process and forming equipment to be tested . Followed by a combination of reverse engineering technology with multi - point forming technology to reverse shape of the hood , including data acquisition , data processing , surface reconstruction and surface analysis . Then , based on the the hood surface model derived on the basis of commercial finite element software ANSYS using Visual C hood as a platform for multi-point forming parametric modeling . Finally, the multi-point forming special software to analyze the hood multi-point forming test whether . Basic body shape adjusting multi-point press test . Forming multi-point auto cover some of the theoretical and experimental basis for multi-point forming better use of automobile covering parts forming process .
