How to adjust the bending speed of automatic pipe bending machine?

It is important to control the bending speed of the universal pipe bending machine to ensure the pipe’s quality. So, We should choose a suitable bending speed while ensuring processing efficiency for the high-quality bending pipes. Yansumi Machinery provides the following suggestions.
●The bending speed is too fast
The cnc pipe bending machine hydraulic has a range of forming speeds and the bending speed can not be over this range. If over this range, the pipes will deform, leading to fractures.

●The bending speed is too slow
If the bending speed is too slow, the dies slip, resulting in cause wrinkles and depression in the large-diameter pipes. So, the bending speed should adjust according to requirements during the use of the pipe bending machine, general, the bending speed should be 20%-40% of the maximum bending speed.

What to do if the large pipe bending machine wrinkles?

The bear force between the clamping die of large pipe bending machine and the pipe wall is not uneven, causing wrinkles in the pipes.
1. Clean the debris on the surface of the dies and choose the suitable pipe bending machine die.
2. The gap between the die and pipe wall should be reduced as much as possible to prevent deformation.
3. Check whether the pipe bending machine mandrel is suitable and whether the gap between the mandrel and pipes is large.
4. Check whether the anti-wrinkle die is worn or suitable.
5. Check whether the pressure on the die is insufficient.

How to prevent pipes from deforming by using nc pipe bending machine

The extent of deformation of the pipes depends on the value of the relative bending radius(Rx=R/D) and relative wall thickness(tx=t/D) during the process of using pipe bending machine hydraulic to bend pipes. If the value of the relative bending radius(Rx=R/D) and relative wall thickness(tx=t/D) gets smaller, the greater the degree of deformation. We should control the degree of deformation in the limit ranges for the pipes bending quality. The pipe bending forming limit does not only include the mechanical properties of materials and bending methods but also includes the pipe use requirements. The pipe bending forming limit should include the following points:
1. The maximum elongation deformation within the outer stretching deformation zone of the neutral layer does not exceed the material's allowable plasticity value, thereby preventing fracture.
2. Within the inner compression deformation zone of the neutral layer, the thin-walled structural components subjected to tangential compressive stress should not become unstable and result in wrinkling.
3. When there is a requirement for ovality in the pipe fittings, a mandrel can be used to control the distortion of its cross-section.
4. If pipes have strength requirements to withstand internal pressure, the forming limit of wall thickness thinning needs to be controlled.
