Description
Technical field
The present invention relates to a kind of circular-arc bending machine, belong to machine for press-bending metal sheet.
Background technology
Circular-arc bending machine, be widely used in the manufacturings such as domestic refrigerator, commercial display cases, regulator cubicle, metal safe, these manufacturing enterprises similar use bender.
Method bending conventional during circular arc bending is as Fig. 1,2, turnover panel (101) drives lower cutting die (102) to rotate around swaging die (103) center of arc, lower cutting die (102) promotes plate (104) and rotates, plate forms fillet, have relative motion between cutting die (102) and plate (104) under this bending method, plate surface easily scratches.The method of current solution is as Fig. 2, at lower cutting die (105), roller (106) is set, plate surface can be improved easily scratch, but roller (106) itself, slip between roller (106) and lower cutting die (105) or roll by as rubbed, lubricating or the factor such as dust affects, not smooth sometimes, also can produce plate surface easily to scratch, and this structural requirement accuracy of manufacture is high, cost is high.
Summary of the invention
In order to the defect that plate surface when overcoming above existing bender folding arc chord angle easily scratches, the invention provides that a kind of plate surface can not scratch, the circular-arc bending machine of low cost of manufacture.
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, the connecting rod of two ends with jack is provided with between described hinge seat and hinge, 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; The axle of described hinge seat is provided with fixed gear, described turnover panel is provided with the moving gear engaged with 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 be fixed in frame hinged, and the piston rod of cylinder or oil cylinder fixes cylinder head; Described journal stirrup to be fixed on described turnover panel and 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 is equal 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.
Be arc surface above described lower cutting die, and the radius of arc surface equal moving gear reference radius.
During bending, binder parts push down plate, piston rod in cylinder or oil cylinder extends, promotion turnover panel and lower cutting die are rotated up around the axle center of hinge seat by the connection of connecting rod, simultaneously because fixed gear engages turnover panel with moving gear and lower cutting die rotates around hinge axis, plate is made to 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 hinge axis rotation on the one hand, moving gear drives turnover panel and lower cutting die to be revolved 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 on lower cutting die, the radius of the arc surface of plane equals moving gear reference radius, revolution makes the arc surface of the upper plane of lower cutting die and plate be formed to roll, and ensure that between the arc surface of the upper plane of cutting die and plate, nothing rubs.
The invention has the beneficial effects as follows: during this bender folding circular arc due to when the effect of planet circular system ensure that plate bending without scratch, no marking, and easily to manufacture.
