Parameters

The elbow is a kind of pipe fitting used at the turn of the pipeline. Among all the pipe fittings used in the piping system, the proportion is relatively large, about 80%. Generally, different forming processes are selected for elbows of different materials or wall thickness. The commonly used seamless elbow forming processes in manufacturing plants include hot pushing, stamping, and extrusion. So do you know what its hot forming process is? Let's follow the editor of Elbow for water treatment to have a simple understanding!
The hot push elbow forming process is to use a special elbow push machine, core mold and heating device, so that the blank sleeved on the mold moves forward under the push of the push machine, and 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 constant volume before and after the plastic deformation of the metal material. The diameter of the tube blank is smaller than the diameter of the elbow, and the deformation process of the blank is controlled by the core mold, so that the inner arc is compressed The metal flow is compensated to other parts that are thinned due to diameter expansion, so as to obtain an elbow with uniform wall thickness.
The hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production. Therefore, it has become the main forming method for carbon steel and alloy steel elbows, and is also applied to certain specifications of stainless steel elbows. Is forming.
The heating methods of the forming process include medium-frequency or high-frequency induction heating (the heating ring can be multi-turn or single-turn), flame heating and reverberatory furnace heating. The heating method used depends on the requirements of the formed product and the energy situation.
To sum up, the editor of Elbow for water treatment tells: a brief introduction to the related knowledge of the hot forming process of the elbow, you can learn more.
