【正文】 ngth steel plate to auto parts, so as to realize the lightweight and high deformation capacity of the body. But the traditional cold stamping technology has been unable to achieve such special steel plate processing, new type of thermal shock technology arises at the historic moment. This technology through special steel heated to 950 ℃ or so, form the austenitizing, then in punching machine for quick stamping forming, and processing of ultra high strength automobile spare parts. Designed by this paper is aimed at the steel plate for the mechanical structural design of the roller bottom furnace heated. Rollerhearth furnace can work according to certain rhythm, a steady stream of steel plate for heating, very conducive to mass production. The overall train of thought of this design USES the modular, subsystem design. Divided into the furnace body, heating, transmission, oven door and accessory, for jacking in a total of five subsystem design. The kiln body with the method of unit assembly, an upgraded version of a subsequent development provides a good range of motion. Finally realize the mechanical structural design of roller hearth furnace. Keywords: Roller hearth furnace。 Heat treatment。 The structure design。 哈爾濱工業(yè)大學(xué)本科畢業(yè)設(shè)計(jì)（論文） IV 目 錄 摘 要 .......................................................................................................I ABSTRACT...........................................................................................
