| Analysis of four characteristics of pipe bender
The process of pipe bender can prevent the asymmetry of pipe wall thickness caused by the thinning of the convex edge and the thickening of the concave edge under pressure during the traditional bending process.
The pipe bender process can produce 180 elbow with small radius (R≈D) and thin wall (t/D≈0.015) with symmetrical wall thickness, which can not be realized by other bending process.
If the process parameters of the bending machine are reasonable, the process can ensure that the wall thickness of each part of the bending process is always connected and stable, that is, the straight blank wall thickness before deformation.
The process can be in the uniform horn mandrel push a similar caliber of 45, 90, 180 and other bending Angle of the elbow, production obey high.
