Pipe bending machine in pipe fitting equipment is briefly introduced  

Pipe bending machine and hydraulic pipe bending machine is a kind of pipe fitting equipment, which is also made by using hydraulic force or high temperature bending of the blanking billet. The bending pipe made by hydraulic pressure is beautiful in appearance and straight and barrier-free resistance, and the production efficiency and quality are better.  Elbow push machine equipment mainly includes: frame, main cylinder support plate (including main cylinder), movable push plate, elbow clamp platform, elbow rocker arm, rocker arm rotating shaft, elbow combination clamp, intermediate frequency transformer support, intermediate frequency power supply, intermediate frequency transformer, electrical control system and so on.  And it can control the large diameter intermediate frequency heating pipe bender to improve the response speed of pushing pipe speed to the heating temperature change;  Compared with the traditional one, it can improve the precise control ability of the process and make the control system have good control performance.  

The parameter value of intermediate frequency pipe bender has a lot of articles, the size of the pipe bend number diameter of the hydraulic intermediate frequency pipe bender in the first proper choice of half diameter determines the size of the resistance of the pipe in the tortuous forming.  Generally speaking, the diameter of the pipe is large and half of the diameter is small. When the pipe is tortuous, it is difficult to ensure the tortuous quality. It is better to choose the R value of the bending mold as 2 or 3 times the diameter of the pipe.  In the process of selecting suitable mandrel and its azimuth hydraulic intermediate frequency pipe bender, the main function is to support the inner wall of half diameter of pipe bend to prevent its deformation.  

Bending machine is now domestic in the machine tool zigzag forming without the use of mandrel, its quality is difficult to ensure.  There are many methods of mandrel.  In addition, the direction of the mandrel also has a positive influence on the bending forming of the pipe. Theoretically, its tangent line is even with that of the bending die, but after many practices, it is proved that 1-2mm in advance is better, which is the ideal proportion of the bending mass.  

Moderate winding forming rate set out for the main effect of the forming quality, the rate is too fast, simple form catheter and some flat, roundness short of supplication, pipe bend machine form ripping, snap, speed too slow simple form a sliding, catheter wrinkling and compaction of big diameter pipe abnormity tube some twists and turns of subsidence.  For many applications on these two hydraulic intermediate frequency pipe benders, it is advisable to set the pipe tortuous rate at 20-40% of the mechanical large tortuous rate.
