The course of work of the board clamp device of the full-automatic plate change of a kind of offset press of the present utility model is:
It is by gear drive 6 by motor that clamping, the clamp bar of clamp bar seaming side drags the slightly clamping of side and the tensioning of forme, power is passed to plate change cam 5, plate change cam 5 drives seaming sides action forks 28, drags tip side action fork 38 and tensioning action fork 48, thus realize forme clamping, unclamp.
In machine normal operation situation, seaming side action fork 28, to drag the bearing end that holds with arbor of slightly side action fork 38 and tensioning action fork 48 be not in plate change cam 5 cam paths, and seaming side action fork 28, to drag the non-bearing end that holds with arbor of slightly side action fork 38 and tensioning action fork 48 be the seaming side action groove 12 that is embedded in correspondingly plate cylinder 1 all the time, drag in slightly side action groove 11 and tensioning action groove 13.
during the clamping forme: at first, the operator forwards plate cylinder 1 to respective angles, press again the action button of motor, motor-driven gear transmission mechanism 6 rotations this moment, power is passed to plate change cam 5, when plate change cam 5 turns to the bearing end position of holding with arbor of seaming side action fork 28, the bearing end that holds with arbor of seaming side action fork 28 is snapped in the cam path of plate change cam 5, plate change cam 5 is passed to seaming side action fork 28 to power, seaming side action fork 28 swings, thereby make seaming side action axle 26 forward high face to by bottom surface, the seaming limit clamping of the forme that imports seaming side clamp mechanism, then press the action button of main transmission and rotate plate cylinder 1, forme is twisted in the surface of plate cylinder 1, forward to when dragging slightly the side clamp mechanism, forme dragged slightly the limit to be pressed into to drag slightly the side upper clamp bar 31 times, continue drive motors, when plate change cam 5 turns to the bearing end position of holding with arbor of dragging the action of side slightly fork 38, dragging slightly, the bearing end that holds with arbor of side action fork 38 is snapped in the cam path of plate change cam 5, slightly side action fork 38 is dragged in drive, drag slightly side action axle 36 to forward high face to by bottom surface thereby make, forme dragged slightly that the limit clamps, at last, continue drive motors, when plate change cam 5 turns to the bearing end position of holding with arbor of tensioning action fork 48, the bearing end that holds with arbor of tensioning action fork 48 is snapped in the cam path of plate change cam 5, driving tensioning action fork 48 swings, thereby make edition tensioning shaft 43 forward high face to by bottom surface, promote to drag slightly that under the side clamp bar, base station 34 moves to seaming side clamp mechanism direction, pull forme that forme is close on the surface of plate cylinder 1.
When taking out forme: after being completed for printing, need to take off forme from plate cylinder 1.The operator presses the action button of main transmission, plate cylinder 1 is forwarded to respective angles, drive motors drives plate change cam 5 again, make tensioning action fork 48 rotate an angle, at this moment, version tensioning shaft 43 forwards bottom surface to from high face, due to the effect of base station returning spring 30, dragging slightly side clamp bar mechanism to shift initial position onto, forme is loosened; Then continue drive motors and drive 5 rotations of plate change cam, make and drag slightly angle of side action side-sway bar 38 swings, owing to dragging slightly side action fork 38 and dragging slightly side to move axle 36 to connect, dragging this moment slightly, side action axle 36 forwards bottom surface to by high face, due to returning spring 37 effects of dragging the mechanism of side clamp bar slightly, drag slightly side upper clamp bar 31 swings, the slightly limit of dragging of unclamping forme; Plate cylinder 1 is rotated further, the slightly surface of limit derivation plate cylinder 1 of dragging of forme; Motor continues to drive plate change cam 5 and rotates, make seaming side action fork 28 swing an angle, thereby make seaming side action axle 26 turn to bottom surface by high face, effect due to the back-moving spring 27 of seaming side clamp mechanism, seaming side upper clamp bar 21 is swung, thereby unclamped the seaming limit of forme, forme is derived by the composing mechanism of full-automatic plate change again.
Offer on the lateral surface of plate cylinder 1 drag the action of side slightly groove 11, seaming side action groove 12 and tensioning action groove 13 be used for limiting seaming side action fork 28, drag the slightly movement locus of side action fork 38 and tensioning action fork 48.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
