Aluminum alloy cold drawing tee machine

Working principle of aluminum alloy cold-drawing tee: when the tee is hot pressed, the tube blank larger than the tee diameter will be compressed to the size of the tee diameter.After heating, the billet is put into the forming die, and the die for drawing branch pipe is loaded into the billet.Under the action of pressure, the billet is compressed radially. During the process of radial compression, the metal flows to the branch pipe and the branch pipe is formed under the drawing of the die.The whole process is formed by the radial compression of the billet and the stretching of the branch pipe.Different from the hydraulic bulging tee, the metal of the hot pressing tee branch pipe is compensated by the radial movement of the tube blank, so it is also called radial compensation process.

Due to the use of heating and pressing the tee, the tonnage of equipment needed for material forming is reduced.Aluminum cold-drawing tee machine has wide adaptability to materials, suitable for low carbon steel, alloy steel, stainless steel materials;Especially for the tee with large diameter and thick wall, this forming process is usually adopted.
