Aluminum alloy cold drawing tee machine

The working principle of aluminum alloy cold drawing tee machine: when the tee is hot pressing, the tube billet larger than the diameter of the tee will be flattened to the size of the diameter of the tee, and a hole will be opened in the stretching branch pipe;The tube billet is heated and put into the forming die, and the punching die of the tensile branch pipe is loaded into the tube billet.Under the action of pressure, the billet is compressed in the radial direction, and in the radial compression process, the metal flows to the branch pipe and forms the branch pipe under the tension of the die.The whole process is formed by the radial compression of the billet and the tensile process of the branch pipe.Different from the hydraulic bulging tee, the metal of the branch pipe of the hot pressing tee is compensated by the radial movement of the billet, so it is also called the radial compensation process.

The tonnage of the equipment required for material forming is reduced due to the use of heated and pressed tees.Aluminum alloy cold drawing tee machine has wide adaptability to materials, suitable for low carbon steel, alloy steel, stainless steel materials;Especially for tee with large diameter and thick pipe wall, this forming process is usually adopted.

The internal high pressure tee machine is a common hydraulic press used for making tee of carbon steel and stainless steel pipe material. It is suitable for extrusion molding of tee fittings of various specifications to change the position of side cylinder. It can process and manufacture tee fittings of 90 degrees, 135 degrees and other angles.In high pressure tee machine has independent power structure and electrical system, PLC programmable controller, which can realize point, manual, semiautomatic and fully automatic four kinds of operation mode, automatic function with cavity filling, increases, the pressure part adopts the advanced hydraulic control technology, increase the stability and reliability of the high pressure tee machine rational layout, use convenient maintenance, reliable operation, high production efficiency, product quality well.

The operation steps of the internal high pressure three-way machine are as follows: first, the fixing plate is placed inside the cavity, and then one end of the pipe fitting is placed inside the groove of the fixing plate. At this time, the outer wall of the pipe fitting is in contact with the upper end face of the belt.The driving pulley is then rotated to drive the belt and the driven pulley.Use the static friction force between the outer wall of the pipe fitting and the belt and the thrust force of the operator to push the pipe fitting placed on the belt to the fixed plate along the opening direction of the groove.After the pipe fittings are completely placed on the fixed plate, the starting hydraulic cylinder is extended to push the fixed plate and the pipe fittings placed on the fixed plate upward, and then the pipe fittings are welded.The hydraulic cylinder is used to control the lifting height of the fixed plate, and the belt, the driving pulley and the driven pulley are used to drive the pipe fittings to be placed on the fixed plate, which facilitates the feeding of large caliber pipe fittings and reduces the labor intensity of the operator.
