Chiho Hebei steel stamping elbow pipe industry manufacturer of the steel stamping elbow needs normalizing heat treatment, machining port, wall thickness and the need to leave the burning plane allowance. Usually the balance of the theoretical thickness of the elbow 10% to 20%. Elbow-sectional diameter and wall thickness δ D ratio is smaller, the better the performance and fit the mold, but inside the arc bends more easily wrinkling. The metal plastic deformation during constant volume, pushing molding constant wall thickness (actual micro-thinning), equal to the length of the outer arc tube elbow-length features, the outside diameter of the tube to push the system to derive the formula: If the actual choice of tube diameter ratio calculated according to the formula Dp value small stamping elbow 45 degrees, and fit the mold of good performance, but within easy wrinkling elbow arc. If the actual choice of tube diameter ratio calculated according to the formula Dp value Seamless stamping elbow 45 degrees, the result is just the opposite. Determine the principle steel stamping manufacturer elbow elbow inner wall of the heating temperature is less than the principal compressive stress in the material yield strength of the material at this temperature austenitizing temperature or higher, and when to push the system. Material austenitizing temperature, the higher the heating temperature; yield limit of the material temperature, the higher the heating temperature. Chiho Hebei Industry GB stamping elbow cold stamping and hot stamping division two, usually choose cold or hot stamping stamping equipment according to the material properties and the ability to cold extrusion process is the use of a dedicated elbow elbow forming machine, the tube into the outer mold, mold clamping down after punching a 45-degree elbow prices at putting the impetus of the tube along the inner and outer dies reserved space movement forming process is completed. stamping elbow is forming process was first used in production of seamless elbow, at present, the production of common specifications elbow has been replaced by extrapolation or other hot forming process, but in some specifications due to a small number of production elbow, wall still use too thick or thicker product with special requirements. elbow and elbow using stamping outer diameter equal to the tube, using a press in a mold direct compression molded Before stamping, tube placed on the lower die the inner core and the end of the tube into the mold, the mold pressing downward movement began, through the outer mold and the mold constraints make elbow forming a supporting role. Compared with hot push technology, visual quality is better than the former stamping ; stamping elbow outer arc during molding in a stretched state, there is no other parts of the excess metal to compensate, so that the wall thickness at the outer arc of about 10%, but due to the thinning for single-piece production and low cost. So much for stamping elbow craft small batches, thick-walled elbow elbow stamping manufacturing GB Features: 1, temperature and pressure, flexibility, heat resistance, and its performance is higher than other plastic pipe installation is simple and good thermal conductivity suitable for floor heating systems, recyclability. 2, P GB stamping elbow pipe has its excellent impact strength, fusion welding and mechanical connections, better than PB-PP-R thermal conductivity. 45 degree elbow stamping specifications, quality and cheap, Huaian stamping elbow 45 degrees provided by Chiho Hebei Industry Co., Ltd.
