The hot push elbow forming process uses a special elbow pusher, a core mold and a heating device, so that the blank placed on the mold moves forward under the push of the pusher, is heated, expanded, and bent during the movement. the process of. The deformation characteristic of the hot push elbow is to determine the diameter of the tube blank according to the law of the volume change of the metal material before and after plastic deformation. The diameter of the tube blank used is smaller than the diameter of the elbow, and the deformation process of the billet is controlled by the core mold to compress the inner arc. The flow of the metal compensates for other portions that are thinned by the expansion of the diameter, thereby obtaining an elbow having a uniform wall thickness.
The hot-bending elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production. Therefore, it is the main forming method for carbon steel and alloy steel elbows, and is also applied to some specifications of stainless steel elbows. Forming.
The heating process of the forming process includes medium frequency or high frequency induction heating (the heating coil can be multi-turn or single turn), flame heating and reverberatory furnace heating, and the heating method is determined by the forming product requirements and energy conditions.
