Compared with prior art, the utlity model has following beneficial effect:

1, the axis of revolution center of turnover panel is not arranged on the joint portion of stirring arm transverse arm and perpendicular arm, but move forward on the transverse arm of stirring arm, moment of torsion when utilizing the stirring arm that the counterweight of being turned over object is made turnover panel greatly reduces, thereby reduced propulsive effort, taken full advantage of the weight that is reversed material self and realize upset;

2, solved propulsive effort that the upset of original single armed needs and to the requirement of Equipment Foundations, equipment is oversimplified, not fragile, base, bearing seat, bearing to supporting revolving shaft point in the switching process have all reduced side force and moment of torsion, make it durable in use;

3, drive oil cylinder and blank level and install, shortened the stroke of oil cylinder;

4, reduced the investment of user to Equipment Foundations, constriction the floor area of panel turnover machine, reduced the maintenance cost that the user uses panel turnover machine;

5, the stirring arm of each positioning machine only uses an oil cylinder as propulsive effort, has solved in the past to be done to drive the oil cylinder stationary problem that produces by two or more oil cylinders, and has made equipment more succinct.
