How to design the parameters of medium frequency pipe bender

The parameter value of intermediate frequency pipe bender is very important. First, the size of the pipe bending number diameter of the hydraulic intermediate frequency pipe bender with the proper curvature half diameter value determines the resistance of the pipe in the zigzag forming.Generally speaking, the diameter of the pipe is large and half of the diameter is small, and the zigzag occurs simply in the case of wrinkling and skidding. It is difficult to ensure the zigzag quality, so it is better to choose the R value of the bending pipe die as 2 or 3 times of the pipe diameter.The selection of the corresponding mandrel and the mandrel of the azimuth hydraulic medium frequency pipe bender mainly supports the inner wall of the half diameter of the pipe bend to prevent its deformation.

Elbow machine is now made in machine tool zigzag forming without the use of mandil, its quality is difficult to ensure.There are many methods of mandrel.In addition, the mandril's orientation also has a positive influence on the tube bending forming. In theory, the tangent line of the mandril is even with the tangent line of the bending die. However, many practices have proved that it is better to advance 1-2mm, which is the ideal mass ratio of the bending pipe now.

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 medium frequency pipe benders, it is advisable to set the tube bending rate as 20-40% of the maximum bending rate of the machine.

Composition and function of pipe bender

Pipe bender is a kind of pipe fitting equipment in pipe fitting equipment.In pipe fitting equipment, pipe bender is mainly composed of four major institutions, power source mechanism, clamping and fixing mechanism, bending radius adjustment machinery, and propulsion mechanism.The pipe bender in the pipe fitting equipment mainly includes: frame, main cylinder, movable push plate, elbow clamp wheel platform, elbow rocker arm, rocker arm track, rocker arm shaft, intermediate frequency power supply, intermediate frequency transformer, electrical control system and so on.

The mechanical part of the pipe bender is equipped with four major mechanisms, which are power source mechanism, clamping and fixing mechanism, bending radius adjusting mechanism and pushing mechanism.

We can make the bend diameter of the pipe bender from 21-1620mm and the wall thickness from 3-100mm.Hydraulic medium frequency pipe bender can be used for carbon steel, alloy, stainless steel steel pipe of any material.

The pipe bender has automatic system function, which can improve the working ability of the equipment. With years of design and maintenance experience, the layout of the whole machine is more reasonable, the equipment is convenient to install, the operation is stable and easy to maintain.The intermediate frequency pipe bender has the advantages of simple operation, long life, low noise, multi-purpose, high quality and low price, etc. It is the supporting equipment for the mechanized production of steel pipe. The market of this equipment can greatly reduce the labor intensity of workers and improve the production efficiency of enterprises.Medium frequency pipe bender is designed and manufactured for large caliber pipe engineering and the growing market demand for various specifications of pipe bender.
