Knowledge of pipe shape regularization of double head hydraulic pipe bender

Help everyone to understand the common sense of pipe shape regularization of double head hydraulic pipe bender: the pipe shape should be composed of straight line segments and circular arc segments. Compound bending, excessive circular arc, arbitrary curve and circular arc greater than 180 ℃ shall be prevented. This is due to:

Too large circular arc not only makes the tooling bulky, but also is bound by the specification of pipe bending machine tool. In fact, the fuel manifold with too large arc and radius even larger than the cross section of the engine can be replaced by a polygon similar to a circle. The fuel main pipe of Spey engine adopts this polygonal structure.
Arbitrary curves and compound bends, which are very unreasonable in planning and modeling, greatly hinder the mechanized and automatic production, and make it difficult for the operator to disconnect from the crude physical labor. In fact, practice has long proved that arbitrary curves and compound bends can also be replaced by broken lines under the condition that their pipe shape trend remains unchanged.
As for the circular arc greater than 180 ℃, it should be prevented as much as possible in the planning and modeling. Because of it, the modular pipe bender cannot unload the die.
At the same time, the straight-line segment between the two arc segments should not be less than 2 to 3 times the outer diameter of the pipe, because the clamping die can clamp the pipe if the machine bending is carried out smoothly.
