Circular-arc bending machine of the present invention, comprise frame, binder parts, bending component, it is characterized in that: described bending component comprises hinge seat, hinge, turnover panel, lower cutting die, cylinder or oil cylinder, free bearing and journal stirrup, described hinge seat is fixed in frame, described hinges fixing fixes on turnover panel, between described hinge seat and hinge, be provided with two ends with the connecting rod of jack, the axle of described hinge seat coordinates with the jack of one end of connecting rod, and the axle on described hinge coordinates with the jack of the other end of described connecting rod; On the axle of described hinge seat, be provided with fixed gear, described turnover panel is provided with the moving gear with the engagement of described fixed gear, and what wherein said fixed gear, moving gear and connecting rod formed is planet circular system, and fixed gear is centre wheel, moving gear is planetary gear, and connecting rod is H bar; Described lower cutting die is arranged on described turnover panel; Described cylinder or oil cylinder and the free bearing being fixed in frame are hinged, and fixing cylinder head on the piston rod of cylinder or oil cylinder; Described journal stirrup is fixed on described turnover panel and is hinged with described cylinder head.
Described fixed gear is fixed on the axle of described hinge seat, and the reference diameter of described fixed gear equates with the arc diameter of swaging die.
Described moving gear is a part for complete gear wheel and is fixed on hinge.
The pitch-row A of the jack at connecting rod two ends equals the arc radius sum of fixed gear reference radius and arc surface.
Above described lower cutting die, be arc surface, and the radius of arc surface equal moving gear reference radius.
During bending, binder parts are pushed down plate, piston rod in cylinder or oil cylinder extends, promotion turnover panel and lower cutting die rotate up around the axle center of hinge seat by the connection of connecting rod, while is due to fixed gear and moving gear meshes turnover panel and lower cutting die rotates around hinge axle center, makes plate form required upwards bending angle.Due to fixed gear, moving gear and connecting rod composition is planet circular system, fixed gear is centre wheel, moving gear is planetary gear, connecting rod is H bar, so moving gear drives turnover panel and lower cutting die around the rotation of hinge axle center on the one hand, moving gear drives turnover panel and lower cutting die to revolve round the sun around the axle center of hinge seat by the connection of connecting rod on the other hand.Rotation makes plate form required circular shape, because the radius of the arc surface of plane on lower cutting die equals moving gear reference radius, revolution forms arc surface and the plate of the upper plane of lower cutting die to roll, and has guaranteed between the arc surface of upper plane of cutting die and plate without rubbing.
The invention has the beneficial effects as follows: while having guaranteed plate bending due to the effect of planet circular system during this bender folding circular arc, without scratch, no marking, and easily manufacture.
