The forming process of stainless steel elbow 2018-11-30 The forming process of stainless steel elbow in cold extrusion elbow is to use a special elbow forming machine, put the tube blank into the outer mold, and after the upper and lower molds are closed, in the push rod Push to take shape. Its appearance is beautiful, the wall thickness is uniform, and the size deviation is small. Therefore, this process is often used for the forming of stainless steel elbows, especially thin-walled stainless steel elbows. The precision requirements of the inner and outer molds used in this process are high; the requirements for the wall thickness deviation of the tube blank are also strict. The forming process of stainless steel elbows 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 it is also used in some specifications of stamping elbows. 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. Stamping and forming stainless steel elbows is an early forming process used in mass production of stainless steel elbows. Perhaps some developers will think that odor-resistant floor drains are enough. Engineering practice has proved that odor-resistant floor drains are far from meeting actual needs.
