Hot pressing elbow is a kind of elbow made by hot pressing process, which is a kind of pipe fittings.
Hot pressing elbow is a kind of elbow made by hot pressing process, which is a kind of pipe fittings. Positive fire can eliminate the net carburizing body of the over-co-analysis hot-pressing elbow, for the sub-co-analysis hot-pressing elbow positive fire can refine the lattice, improve the comprehensive mechanical properties, the requirement of the elbow with positive fire instead of quenching process is more economical.
hot push forming
The hot push elbow forming process uses a special elbow pushing machine, core mold and heating device to make the blank on the mold move forward under the push of the pushing machine, and is heated, expanded and bent during the movement. process.
The deformation characteristic of the hot push elbow is to determine the diameter of the tube blank according to the law of the same volume before and after plastic deformation of the metal material. The diameter of the tube blank used is less than the diameter of the elbow. The deformation process of the blank is controlled by the core die, so that the compressed metal at the inner arc flows and compensates for other parts that are thinned due to diameter expansion, thus obtaining the elbow with uniform wall thickness.
Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, suitable for mass production, and thus become the main forming method of carbon steel, alloy steel elbow, and also used in some specifications of stainless steel elbow forming.
The heating method 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. The heating method depends on the requirements of the formed product and the energy situation.
