Performance Henan stainless steel bar stamping material properties corresponding to the formation of bulge-shaped performance, flanging performance, reaming and bending formability properties. To learn stamping performance must first understand the stamping process. Basic stainless steel wire stainless steel wire and stainless steel rod Henan stamping process are: drawing process, bulging process, flanging process (including reaming), bending process. 1) deep drawing process is the use of special drawing tablet blank mold will cut after punching or stamping was formed into a hollow piece of the process for opening. It features sheet in the punch drive, can flow into the die, which rely on mobility and elongation of materials forming. 2) forming a shaped bulge bulging process is forced to use the blank mold thickness thinning and surface area increases, the method for stamping parts geometry. Characterized blank blank holder is crushed, can not flow into the die, totally dependent on the extension of the forming material itself. 3) flanging flanging process is the use of mold on the hole or the outer edge of the blank side of translated vertical stamping methods. In the intermediate stage before the hole flanging, that punch below the material has not been completely transferred to the side, if you stop the distortion, you get shown to the right of shaping the way, this forming method is called reaming, production and application are also common . 4) bending process is bending sheet metal, bar, pipe material or method of forming certain profiles, such as bent shape and angle of the part. Henan Fung Shing Stainless Steel Co., Ltd. is the first stainless steel stainless steel market in Henan manufacturers. Zhengzhou franchise stainless steel sheet, pipe, elbows, flanges ... especially in Henan stainless steel processing industry is the preferred business co-operation.
