HVAC Equipment Automatic Hairpin Bender Bending Machine for Air Conditioners
1. Product Range
WONDERY is a professional supplier of HVAC equipment such as the automatic hairpin bender machine,
high speed fin press machine, aluminum/copper straightening and cutting machine, welding machine, brazing furnace.
2. Structural features of hairpin bending machine
2.1 Structure: servo fixed length cutting and unloading, fixed vane pump is used in hydraulic system, and servo
motor drives the bending mechanism.
2.2 The whole hairpin bending machine is composed of material rack, cutting machine and bending machine.
The hairpin bender machine can move back and forth in length direction by servo driving ball screw to realize
the production of different length workpieces. Automatic circulation process: straightening → feeding →
pressing → cutting → bending up → core pulling → loosening → unloading → reset.
