Overview of the process of stainless steel elbow
Elbows are a kind of pipe fittings used for turning pipes. Of all the pipe fittings used in the piping system, the largest share is about 80%. In general, different forming processes are selected for different materials or wall thickness bends. Manufacturers commonly used seamless elbow forming process hot push, stamping, extrusion and so on.
Heat forming
The hot-bending bending head forming process adopts a special elbow pushing machine, a mandrel and a heating device, so that the billet placed on the die is moved forward by the pushing machine and heated, expanded and bent during the movement. the process of. The deformation characteristics of the thermal pusher elbow is to determine the diameter of the blank according to the law of constant volume before and after the plastic deformation of the metal material. The diameter of the blank used is smaller than the diameter of the elbow. The deformation process of the blank is controlled by the core die, so that the internal arc is compressed. The metal flow is compensated to other parts that are thinned due to the expansion, resulting in an elbow with a uniform wall thickness.
The hot-pushing head forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production. Therefore, it has become a main shaping method for carbon steel and alloy steel elbows, and is also applied to certain specifications of stainless steel elbows. The formation of.
Heating methods in the forming process include medium-frequency or high-frequency induction heating (multi-turn or single-turn heating coils), flame heating, and reverberatory furnace heating. The heating method used depends on the product requirements and energy conditions. Any size large elbow with an inner diameter greater than 1.5 times the elbow diameter is an ideal method for manufacturing large carbon steel elbows.
