Fig. 6 shows bending mechanism 100 and is in impaction state, at this point, the first cylinder 123 is activated, and the second cylinder 133 is not
It is activated.The first cylinder 123 driving compressed part 120 is moved downward to depressed position shown in fig. 6 as a result, wherein compressed part
120 seal face P2 is pressed against the upper surface of the part in 401 front of end of plate 400, so that compressing plate 400 makes it steadily
Keep current location.At this point, since the second cylinder 133 is not activated, bending part 130 does not rotate, still in the outstanding of diagram
Vertical position.
Fig. 7 shows bending mechanism 100 and is in bending state, at this point, both the first cylinder 123 and the second cylinder 133 quilt
Actuating.Since the holding of the first cylinder 123 is activated, compressed part 120 is still in depressed position above-mentioned.At this point, due to the second gas
Cylinder 133 is also activated, and bending part 130 is swung up 90 degree from hanging position and digs position to shown in Fig. 7.Here, bending part
130 folding surface P3 forces end 401 to surround 90 degree of the upward bending of back edge of seal face P2 against the lower surface of end 401,
To realize Bending Processing.
After completing Bending Processing, while the actuating of the first cylinder 123 and the second cylinder 133 is terminated, is applied to pressure as a result,
Active force in tight portion 120 and bending part 130 disappears simultaneously, so that bending mechanism 100 restores to preparation state shown in fig. 5,
Bending mechanism 100 is left at this point it is possible to move forward and completed the plate 400 of Bending Processing.Since plate 400 is by total each other
The pedestal 110 and supporting table 300 in face support, also, plate 400 can be with lower resistance along the surface of supporting table 300 to advancing slip
Dynamic, therefore, the operation for removing plate 400 only needs seldom manpower to intervene, such as an operator can be easily accomplished.
It is described in detail above for realizing certain most preferred embodiments of the invention and other embodiments, but should manage
Solution, the effect of these embodiments is only that citing, and does not lie in and limit the scope of the invention in any way, is applicable in or construct.
