Development of New Hot Forming Process for High Strength Steel Tubes
نویسندگان
چکیده
The widely adopted the high strength steel tube is an important way to solve lightweight body and collision safety. traditional pressure hydroforming hot gas forming through “expansion” deformation form hollow parts, internal driving force. There are some industrial difficulties such as heavy dependence on pressure, wall thickness thinning low production efficiency, which limits application of high-strength tubes. Based principle compression deformation, this paper develops hydro-forging process After blank heated austenitization, compressed deformed by die closing force a new structure. only plays supporting role, fundamentally avoids cracking under expansion mode, has advantages rapid time uniform quenching. Finally, A-pillar with 1500 MPa formed reasonable process.

Cold End Forming Of Welded Steel Tubes
The production of custom and specific tube end shapes by cold end forming using a die is generally limited to seamless tubular parts. Current research work in the field follows the same trend as that of industry and, therefore, there is no accumulated experience, no practical design rules, and no information available in the specialized literature concerning the utilization of tube end forming ...
متن کاملHot Forming of Aisi A2 Tool Steel
In order to optimize the hot forming process of tool steels, further improvement of flow stress prediction and additional knowledge on hot deformability, especially at lower and upper limits of the hot working range, are required. The hot working ranges for these steels are very narrow as a consequence of the role of alloying elements, which form carbides. Carbides improve tool steel’s hardenab...
متن کاملMetallurgically Consistent Determination of Steel Hot Strength Using Process Data from Hot Strip Mill Rolling
It is not rare to observe an inverse relationship between hot strength determined from rolling load of the finishing stands of the hot strip mill and strain. This situation was already described in the literature and is explained by the use of inverse rolling load models that assumes sticking friction in the determination of hot strength. The aim of this work was to show that this “work softeni...
