Abstract
In this article, it introduced a kind of deformation process determination procedure and trial production of P-shaped section special pipe, which is used in column and frame of construction machinery cab, and compared different deformation process design and trial production results. In order to resolve the dimension differences between the theory design and actual manufacture products, it used finite element simulation analysis to find out the primary cause of inadequate deformation. And through correcting the allocation of materials in arc length around the corner, the effective design method and essential points of operation were obtained. The trial production results showed that the angle, arc, various sizes of products dimension are within the demanding tolerance range.关键词
