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
