Product Description

Product Description

Fully Automatic Hairpin tube Making Machine

This machine is a specialized pipe bending machine for producing hairpin-shaped long U-tubes. A servo system controls the bending, unloading, and stroke control sections, while a frequency converter motor controls the feeding. It features a PLC control system, a human-machine interface, and is available in 8-tube models, with customizable options for various specifications.

Long U pipe bending machine for the plate type copper tube open, straighten, no chip off, bending into a fixed U-tube, Shape hairpin, also known as hairpin tube; mainly used in air-conditioning two long tube U-automatic production.

Features

(1) Servo fixed length and material return , hydraulic system adopts quantitative

(2) hydraulic pump , and swinging oil cylinder drives bending .

(3) The whole machine is composed of material rack , cutting machine and bending machine.

(4) The bending machine can move in the length direction to realize the production of workpieces of different lengths .

(5) Automatic circulation process: straightening  → feeding  → pressing  →   cutting  →Bending up  → core pulling  → loosening  → unloading  → reset .
