Wherein, the 1-die shoe, 2-proofreaies and correct counterdie, and the 3-piercing punch is inserted, 4-first bolt, 5-proofreaies and correct patrix, 6-second bolt, 7-movable pad, 8-guide finger, 9-upper bolster, 10-dovetail vertebra, 11-piercing punch handle, 12-active pull rod, 13-butterfly spring, 14-pressing plate, 15-guide pillar, 16-forging.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
What a kind of shown in Fig. 1～2 was used for the closed die forging part dashes the school mould structure, it comprises die shoe 1, upper bolster 9, piercing punch, proofread and correct patrix 5 and proofread and correct counterdie 2, wherein, be connected by guide pillar 15 between upper bolster 9 and the die shoe 1, and upper bolster 9 can move up and down with respect to die shoe 1, be connected with movable pad 7 at upper bolster 9 lower surfaces by at least three group elasticity active pull rods, proofread and correct patrix 5 and be fixed in movable pad 7 bottoms by the pressing plate 14 and second bolt 6, die shoe 1 upper surface fixed correction counterdie 2, be fixed with the piercing punch that is used for dashing except that forging 16 center through hole gross weights in upper bolster 9, this piercing punch axially runs through movable pad 7 and proofreaies and correct patrix 5 and corresponding with forging 16 center through hole.Above-mentioned piercing punch, correction patrix 5 and correction counterdie 2 are coaxial arrangement.Be connected with guide finger 8 between above-mentioned upper bolster 9 and the movable pad 7, one end of this guide finger 8 stretches into movable pad 7, the other end stretches into upper bolster 9, movable pad 7 can move up and down along guide finger 8, guide finger 8 can improve guiding accuracy, makes piercing punch, correction patrix 5, correction counterdie 2 and forging 16 accurately locate.
In the technique scheme, the elasticity active pull rod comprises active pull rod 12 and butterfly spring 13, active pull rod 12 passes upper bolster 9 and links to each other with movable pad 7 with butterfly spring 13, wherein, the flange of active pull rod 12 1 ends matches with the groove of upper bolster 9, and active pull rod 12 other ends are fixed in the movable pad 7.Can adjust the load of disk spring 13 by size, quantity, compound mode, the decrement of adjusting butterfly spring 13, satisfy the calibrated force requirement of different hot forgings 16.Among Fig. 1, the distance H of the flange of active pull rod 12 1 ends and the bottom portion of groove of upper bolster 9 is the material returned stroke of butterfly spring 13 after the punching, disk spring 13 has certain pre compressed magnitude, therefore above-mentioned distance H is adjusted the material returned stroke of disk spring 13 less than the total decrement of disk spring 13 by adjusting above-mentioned distance H.Among the figure in 1 h be the punching stroke, material returned stroke H is greater than punching stroke h.
In the technique scheme, piercing punch comprises that piercing punch handle 11 and piercing punch insert 3, and piercing punch is inserted and 3 linked to each other with piercing punch handle 11 by first bolt 4.Piercing punch is made split type mould, be convenient to change, also can reduce the die steel material consumption and the manufacturing cost of rapid wear mould.
In the technique scheme, proofread and correct patrix 5 working face external diameters less than forging 16 external diameters 3～5mm.Can avoid enclosed and forge axial burr.
The dovetail awl 10 at the top of the utility model by upper bolster 9 links to each other with forcing press, and forcing press provides power for upper bolster 9 moves up and down.
During the utility model work, upper bolster 9 moves downward by guide pillar 15 under the driving of forcing press, in the piercing punch punching, proofreading and correct patrix 5 contacts with hot forging 16, butterfly spring 13 is compressed and forms compression distance H, and the compression stress of butterfly spring 13 drives correction patrix 5 and simultaneously hot forging carried out thermal recalibration with correction counterdie 2.After punching and thermal recalibration operation were finished, as shown in Figure 2, upper bolster 9 moved upward, the drive piercing punch moves upward, and disk spring 13 elasticity discharge, and promotes to proofread and correct patrix 5 and produces relative motion with piercing punch, compression distance H reverts to zero gradually, realizes the forging material returned after disk spring is to punching.Continue afterwards to move upward, wait for stroke next time.
The content that this specification is not described in detail belongs to this area professional and technical personnel's known prior art.
