Nowadays, bending pipe processing technology has been widely used in various industries, such as the booming automotive and aerospace industries, which often use various bending pipe products. For these professions, the quality of bent pipe processing products will directly affect the structural rationality, safety, and reliability of the products produced by these professions.

 

So, if we want to obtain high-quality bent pipe processing products, we must grasp different process conditions and operational skills. If we choose the cold processing method, we must choose the shape of the core rod reasonably and also grasp the correct application method. We know that after confirming the shape and size of the core rod, its orientation at the beginning of the bend in the pipe is also an important factor affecting the quality of the bent pipe.

 

Therefore, we must strive to ensure its rationality as much as possible. If the inserted direction is too forward, it may cause the outer wall of the bent pipe workpiece to be squeezed and cracked; If the penetration is too small, it will not provide corresponding protection and may even cause wrinkling on the inner side of the arc.

 

So, how should we grasp this suitable direction? In fact, we can combine a formula to make the selection: e ≤ (1/4~1/2) D. The letter e in this formula represents the interval at which the core rod penetrates into the beginning of the pipe bend, while the letter D represents the nominal size of the inner diameter of the bent pipe processed product. Then, specific numerical values can be obtained through calculation.

 

After confirming the orientation dimensions, we should also conduct a bending test based on this value. During the bending process, we can make appropriate adjustments based on specific conditions to achieve the correct orientation of the core rod. In this way, the obtained bent pipe processing products can meet the requirements of application.
