The specific embodiment

Side flanging is inserted and 1 is installed on the die ontology through screw, and rotating shaft installing rack 2 also is to be installed on the die ontology through screw.Rotating shaft 3 one ends are installed on the rotation punch 4, and the other end installs on the rotating shaft installing rack 2, and the rotating shaft 3 at rotation punch 4 two ends will guarantee the axiality of degree of precision.When mechanism was in the operating position, flat bearing 12 supported on the die ontology behind front and back side flat bearing 9,10 that rotates punch 4 and bottom surface, and flat bearing 11 is that the water conservancy project that sits on driving sliding block 7 is done on the plane before rotation punch 4 bottom surfaces.Driving sliding block 7 one ends are connecting air cylinder driven device 6, under the driving of cylinder, can do horizontal movement.Under air cylinder driven, when the inclined working 13 at driving sliding block 7 rear portions begins to contact with rotation punch 4,, rotate punch 4 like this and just can rotate because flat bearing 11 is fallen on the inclined working 13 at driving sliding block 7 rear portions gradually before rotation punch 4 bottom surfaces.The flexible driver 5 in rotation punch 4 rear portions; The spring pin of elastic driver 5 is compressed when mechanism is in the operating position; Elastic driver 5 is installed on the die ontology; After air cylinder driven device 6 began action, compressed spring pin discharged compression stress gradually, helped rotation punch 4 to rotate.The driving cylinder is passed by after certain stroke; Flat bearing 11 breaks away from before driving sliding block 7 and rotation punch 4 bottom surfaces, and the limit journey face 15 of rotation punch 4 is fallen on the limit journey piece 8, limits journey piece 8 to be installed on the die ontology; Limit journey face portion is equipped with buffering polyurethane, can play buffering and quiet effect.Move at last, rotation punch 4 reaches the position of rollback terminal point.At this moment, the motion process from the operating position to the rollback state finishes.To the process of operating position motion, air cylinder driven device 6 shrinks, and pulling force is provided from the position of rollback terminal point.The inclined working 13 at driving sliding block 7 rear portions at first with rotation punch 4 bottom surfaces before flat bearing 11 contact; Be pulled up gradually then; Rotation punch 4 begins to rotate; When flat bearing 11 contact before the working face of driving sliding block 7 and rotation punch 4 bottom surfaces, rotate punch 4 and just be driven to the operating position.When cylinder was retracted to the dead point, the driving process finished.

As the distortion of present embodiment, can the inclined working of driving sliding block 7 be arranged on the front portion, when driving sliding block 7 drives forwards, 4 rotations of driven in rotation punch.The work direction of rotation that can also change rotation punch 4 is for being rotated counterclockwise, and this moment can be with the front and back position transposing of driving sliding block 7 and elastic driver 5, the position of corresponding adjustment rotation punch 4 bottom flat bearings.Can also omit limit journey piece 8 and limit journey face 15, utilize flat bearing 11 realization limit Cheng Gongneng before inclined working and the bottom surface.

Because the contact-making surface of simple and easy rotating mechanism of the present invention is plane contact; Rather than the curved surface of traditional rotating mechanism contact; So design process shaft position choice; And side flanging insert 1 with the selection of rotation punch 4 contact-making surfaces, side flat bearing position choice all has some key points in design before and after rotation punch 4 left and right sides and the bottom surface.As shown in Figure 4; When confirming that rotating shaft and rotation punch 4 are inserted 1 composition surface with side flanging; Must guarantee to do vertical plane from rotating shaft axis of rotation alignment composition surface; The intersection 16 of this vertical plane and composition surface elongated surfaces the locked state in composition surface just can not occur when rotating punch 4 rotations like this beyond punch.In like manner, also can abide by above-mentioned main points for the flat bearing position choice on the rotation punch 4, rotation punch 4 front side flat bearings 9 are slided the intersection 17 of joining face and crossing the vertical plane of rotating shaft 3 shaft center line and are positioned at outside the rotation punch 4; Rotation punch 4 rear side flat bearings 10 are slided the intersection 18 of joining face and crossing the vertical plane of rotating shaft 3 shaft center line and are positioned at outside the rotation punch 4.
