Bending

Pipe/tube bending is bend straight pipe/tube into different angles and curves, and the pipe/tube is wound bending with bending radius (single mode) or two bending radius (double mode) in a cold state. Widely used in automobile manufacturing, aerospace, air conditioning or other industries of various pipe/tube fittings and wire bending.

Bending

Conventional tube material:

Carbon steel: ASTM/ASME A234 WPB, WPC

Alloy: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911, 15Mo3 15CrMoV, 35CrMoV

ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti

ASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H

Low temperature steel: ASTM/ASME A402 WPL3-WPL 6

High performance steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PVC, PPR, RFPP(reinforced polypropylene) and so on.

Aluminum alloy 3003,6061, copper, copper, brass

Type of processing

1. Stamping: Enlarge the tube end to the desired size and shape with the tapered core on the punch.


2. Rolling: Put the core into the cylinder. Push the outer wheel to machine the rounded edge.


3. Forging: Extend the pipe end or part with a die forging machine to reduce the outer diameter of the pipe fitting. Common forgings are rotary, connecting rod and roller.


4. Bending forming: It is completed by stretching, stamping and rolling, including 3-4 rollers, 2 fixed rollers, 1 adjusting roller, and adjusting the roller spacing.
