The manufacturing process of elbow machine

Elbow machine is a traditional product of pipe equipment factory, mainly used in the production of curvature radius 1~2.5D of various diameters and wall thickness of the elbow pipe. With the development of our steel pipe deep processing technology, the product has been advanced technology improvement. The equipment adopts the technology of ultra short stress line conical die expanding, medium frequency induction heating, no back low energy consumption hydraulic transmission, etc. Solenoid directional valve is used to open and close all the gates to realize the dual control of gate site and console. At the same time, the hydraulic clamping of raw steel pipe and other automatic operation technology, combined with our thermal pipe expansion machine technology, the manufacture of four cylinder super thick elbow pipe pushing machine and other hydraulic pushing equipment. Equipped with the constant temperature control of the medium frequency power heating system, the equipment can be operated by one person to control multiple devices, energy saving, health, stable operation and other functions.

The main function of elbow machine is to produce stainless steel elbow. Cold push elbow machine in the production of stainless steel elbow how to install the effect, easy to use in the production process. These points should be paid attention to when installing cold push elbow can be used well.

The main use of elbow machine is: elbow machine is the production of elbow loader, can produce diameter 21-1620mm, the wall thickness of 3-100mm, elbow multiple is 1D carbon steel, alloy steel and other materials.

The process of producing elbow by elbow machine is to use common elbow machine, core die and heating device. Precision seamless steel pipe makes the blank on the die move forward under the push of elbow machine, heating, expanding and bending forming in motion.

The deformation characteristic of hot push elbow is to determine the diameter of the tube blank according to the law of constant volume before and after plastic metal material, the diameter of the tube blank used is less than the diameter of the elbow. By controlling the deformation process of the billet through the core mold, the compressed metal flow in the inner arc can be compensated, and the elbow with uniform wall thickness can be obtained.

Hot push elbow forming process has beautiful appearance, uniform wall thickness, continuous operation function, suitable for mass production, has become the main forming method of carbon steel, alloy steel elbow, also used in some specifications of stainless steel elbow forming.
