The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 6; a kind of Wedge mechanism driven by air cylinder; comprise patrix slide section 31, the wedge bottom that cooperates with patrix slide section 31, the wedge bottom comprises rotating part 32, air cylinder driven portion 33 and the reset portion that rotating part 32 is restPosed.

As Fig. 2, Fig. 3, shown in Figure 4, air cylinder driven portion comprises body 10, pressing plate 2, back-up block 3, bearing 4, bearing fixing piece 16, guide plate 1, guide plate 5, cylinder 6, the limiting plate 27 of positioning cylinder 6, drive block 12, drive block bayonet socket fixed block 13, impeller-hub 14 and cylinder connecting plate 15, drive block 12 is rigidly connected with cylinder 6, the end of drive block 12 and drive block bayonet socket fixed block 13 adapt, impeller-hub 14 is positioned at the other end of drive block bayonet socket fixed block 13, and described drive block 12 and drive block bayonet socket fixed block 13 have can be along the reciprocating stroke perpendicular to described rotating shaft 21.Limit by pressing plate 2 on the drive block bayonet socket fixed block 13, reach both sides below all by guide plate 1 restriction such as grade of fixedlying connected with body 10, the free degree that makes it have only a horizontal direction to slide, thereby under the active force of air cylinder driven, it can only slide in guide plate 1 upper edge cylinder moving direction, and the impeller-hub 14 that is fixed on 13 also moves along the direction of cylinder moving.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, rotating part comprises bearing fixing piece 16, rotating shaft 21, cover plate 22, forces to retract reseting hook 23, turning arm 17 and

guide plate

18,19,20,24, the two ends of rotating shaft 21 put in the bearing of installing in the bearing fixing piece 16, described rotating shaft 21 and turning arm 17 form one, described pressure retracts the below that reseting hook 23 is positioned at turning arm 17, cover plate 22 is positioned at the two ends of rotating shaft 21, and impeller-hub 14 puts in to be forced to retract in the reseting hook 23.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 6, reset portion comprises ejector pin 7, spring bearer plate 9 and power spring 8, and described power spring 8 is positioned at the below of ejector pin 7, has the through hole that ejector pin 7 motions are passed on the spring bearer plate 9.

The punching press incipient stage, the wedge sliding shoe 26 that is fixed in patrix is along with the decline of patrix begins to move downward, simultaneously, cylinder 6 begins to drive drive block 12 rigidly connected with it, and then power is delivered on the drive block bayonet socket fixed block 13, owing to have on the drive block bayonet socket fixed block 13 because pressing plate 2 restrictions, reach both sides below guide plate 1 restriction such as grade of fixedlying connected with body is all arranged, the free degree that makes it have only a horizontal direction to slide, thereby under the active force of air cylinder driven, it can only slide in guide plate 1 upper edge cylinder moving direction, and the impeller-hub 14 that is fixed on 13 also moves along the direction of cylinder moving.After impeller-hub 14 and pressure retract reseting hook 23 and contact, it is slided on guide plate 1, the impeller-hub 14 that is fixed on the drive block 12 also moves along the drive block travel direction.After impeller-hub 14 and pressure retract reseting hook 23 and contact, promote to force to retract reseting hook 23 motions, because forcing to retract reseting hook 23 is fixed on and has only one on the turning arm 17 of the free degree of rotating shaft 21 rotations, and with the particularity of forcing to retract reseting hook 23 contact-making surfaces, force turning arm 17 and fixed thereon 's flange insert,

guide plate

18 and 24 etc., rotate around rotating shaft 21.This moment, slide plate 20 rotations moved downward; promotion ejector pin 7 moves downward and makes power spring 8 begin compression; until

guide plate

18,24 horizontal by 90 jiaos; and with body 10 on corresponding slide guide face fit tightly; this moment, limiting plate 27 was horizontal by 0 degree angle; need the mark index line; and with body 10 on corresponding positive stop lug boss fit tightly; the forming terrace die of turning arm 17 one has also arrived the operating position; be installed in shaping die on the mode slider simultaneously under the driving of patrix drive block, finish forming technology jointly with forming terrace die.

After shaping work was finished, wedge sliding shoe 26 moved upward with patrix and backhaul gradually; Switching cylinder is closed simultaneously, its power that acts on the turning arm oppositely spurs turning arm, and power spring 8 rotate to arrive in the process that operating position and shaping work carries out at turning arm, be in compressive state always, after cylinder action power is reverse, the reaction force of power spring 8 promotes ejector pin 7 and moves upward, and by guide plate 20, power is delivered on the turning arm 17, same because turning arm 17 21 rotations around the shaft, under the shared effect of cylinder action power and acting force of the spring, turning arm 17 and other parts that are fixed on the turning arm rotate return.

By the argumentation of above operation principle, this rotation wedge can be realized the work function of two moving wedges fully as can be seen, and topology layout compact and reasonable more, has reduced volume, greatly reduces production cost.

Air cylinder driven portion provides power, promotes turning arm and is rotated around rotating shaft, and rotating part is by the rotation of turning arm, makes the position with the forming terrace die arrival work of turning arm one, and then realizes forming technology such as flanging and restriking; Reset portion is the driving by power spring, makes turning arm get back to original state, to eliminate it taking-up is had the obstruction of the product of negative angle, and product can be taken out smoothly.
