Seamless elbow: elbow is a kind of pipe fitting used for turning of pipe. In the pipeline system used in all the pipe fittings, the largest proportion, about 80%. In general, different forming processes are selected for different materials or wall thicknesses. At present, the factory used seamless elbow forming process, hot stamping, extrusion have.
Hot bend forming process is the special Elbow push processing machine, a core mold and a heating device, which makes in the mold blank in pushing mechanism driven by forward motion and in the movement is heating, expanding diameter and bending forming process. The deformation characteristics of the hot pushing elbow is based on the metal plastic deformation before and after constant volume law to determine the tube diameter, the tube diameter less than the diameter of the elbow, the through mandrel control the blank deformation process, the arc by the compression of the metal flow, compensation for expanding and other parts of the thin, in order to get uniform wall thickness of elbow.
The hot pushing elbow forming process has the advantages of beautiful appearance, uniform thickness and continuous operation, suitable for mass production. Therefore, it becomes the main processing method of carbon steel, alloy steel elbow, and is also used in some specifications of stainless steel elbow forming.
The heating method of forming process has the intermediate frequency or high-frequency induction heating (the heating coil can be multi circle or single ring), the flame heating and the reflection furnace heating.
