Automatic Half-Pipe Forming and Spiral Winding Machine

Automatic Half-Pipe Forming and Spiral Winding Machine

The haibao robot automatic half-pipe forming and spiral winding machine combines uncoiling, multi-roll preforming, half-round forming and winding on a shared machine base. It is designed for half-pipe jackets on reactor, heat-exchanger and storage-vessel shells.

From steel strip to a spiral half-pipe jacket

A continuous forming and winding sequence

Slit coil strip enters the uncoiler and preforming rolls before passing through the inclined forming head. Shell rotation and axial feed coordinate the spiral pitch. The formed jacket is positioned for subsequent tack welding, full welding and inspection.

Adjust the forming head to the shell

The inclined column provides height and angular adjustment. Forming rolls progressively develop the half-round section, while the linear guide supports axial movement. Roller tooling, force and speed are selected for material springback and the required section.

Control feeding, rotation and pitch

A PLC and touch-screen interface support parameter setting and manual or automatic operation. The reference arrangement includes variable-speed drives, a handheld operating box, guarding and interlocks. Final controls and safety provisions are defined in the equipment agreement.

Reference delivery and selection range

The reference line was supplied to Anhui Saide Qirui, part of the Hongsong Technology Group. The ranges below are published typical values for this equipment family, not a guarantee for every combination of material, diameter and thickness.

What happens after forming?

This machine forms and positions the half-pipe jacket. The vessel fabrication plan must also define attachment welding, weld inspection and the pressure-boundary requirements of the finished jacket.
