Tube bending is a cornerstone process across industries, offering an array of techniques tailored to materials, specifications, and applications. There are several different types of tube bending. Check them out below.
Rotary Draw Bending (and Mandrel Tube Bending):
With rotary draw bending, tubes dance to the rhythm of a rotating bend die while a counter-die applies pressure, yielding precision and tight-radius bends.
Advantages:
This method boasts exceptional precision, capable of achieving intricate bends.
Disadvantages:
However, its setup cost can be prohibitive, requiring different tooling for varied bends.
Press Bending:
Press bending employs sheer force via a press to mould tubes around a bend die, offering a cost-effective approach with minimal tooling requirements.
Advantages:
Its simplicity and affordability make it an attractive option.
Disadvantages:
Yet, it can succumb to tube crushing, suffer from poor accuracy, and operate at a slower pace.
Roll Bending (Pyramid Rolling):
Roll bending orchestrates a tube’s transformation through a series of rollers, gracefully shaping it into circular or spiral forms, ideal for large-radius bends.
Advantages:
It accommodates diverse tube sizes without necessitating tooling changes.
Disadvantages:
However, its leisurely pace and propensity for tube damage pose notable drawbacks.
Compression Bending:
Harnessing external force, compression bending coerces tubes around a stationary bend die, embodying simplicity and efficiency.
Advantages:
Its straightforward approach ensures swift production.
Disadvantages:
Yet, it’s ill-suited for small-radius bends, limiting its applicability.
