Semi Automatic Hairpin Bender , Hairpin Bending Machine
1. Application
The semi-automatich hairpin bender is simple and of compact
design structure. It is suitable for low volume production of
hairpin
bends. It can be used to bend the hairpin bend with length from
200mm to 3000mm. The semi automatic hairpin bender can produce
hairpin bends with 4 pcs per cycle and 5 pcs per cylce according to
diffrent specification and application.
2. Structure Features
1.1 The semi automatic haripin bender is of compact design.
1.2 It is designed with servo motor driving.
1.3 It is with manual feeding.
2. How does a semi automatic hairpin bender work?
First material feeding by manual → mold tooling clamping → oil
spraying→
bending→ mandrel back→ clamp release→ unloading the hairpin bend→
unloading mechanism return to origin→ bending mechanism return to
origin
