Elbow points stamping cold stamping and hot stamping stamping elbow Hebei two manufacturers often choose cold stamping or hot stamping based on material properties and equipment capacity. Before stamping, tube placed on the lower mold, the inner core and the end of the tube into the mold, the mold downward movement began pressing, die by the constraints and supporting role within the outer mold to make elbow shape. Compared with hot push technology, visual quality is better than the former stamping; stamping elbow when forming outside the arc in tension stamping stainless steel long radius elbow, no other parts of the excess metal to compensate, so the wall thickness at the outer arc thinned to about 10%. However, due to apply to single-piece production and low cost, it is used for stamping elbow craft small batches, thick-walled elbow manufacturing. Stamping elbow belongs to a bend, and its production has a certain process, molding process is complex stamping elbow Hebei Mengcun elbow stamping plant, depending on the need for welding materials and uses in certain pressure carried out gradually forming. Forming stamping elbow elbow need to follow certain procedures stamping elbow, strict adherence to the corresponding flow process or produce stamping elbow will have quality problems. If necessary, a circular ring shell can be cut four 90-degree elbow or six 60-degree elbow or other specifications of the elbow, the process for the manufacture of elbow and elbow in diameter than the inside diameter larger than any specification 1.5 Large push elbow, is an ideal method of manufacturing large push elbow.
