Method of manufacturing a hollow body elements, hollow body element parts assembly, hollow body element production for progressive die tools and rolling mechanism

摘要

Put the parts made by (280) of steel, for example, relates to a process for the preparation of (200) hollow body elements such as nut elements, in particular, the present invention has a rectangular profile or square basic (202), usually a process for producing a hollow body element. Using the (10) continuous composite tool configured work stations some after punched hole (204) in advance the profile, the method, in the form of the winding material profiles or rods (1) It consists of the cutting elements of the individual profiles. The present invention is characterized in that the stamping and punching process is carried out in the work station. The present invention is a hollow body element (200), parts, tools and continuous composite (10), the rolling mill and on (600, 602).
