Fig. 2 the utility model essence is rushed the outer ferrule structure schematic diagram of die.
The specific embodiment
Now by reference to the accompanying drawings, the utility model specific embodiment is described in detail in detail:
As shown in Figure 1 and Figure 2, a kind of brake steel backing fine blanking die that improves dimensional stability and die service life, comprises upper die and lower die, and patrix comprises that cope match-plate pattern 1, upper padding plate 2, clamping plate 16, guide pillar 3, essence rush punch 15, stripper plate 5, contour screw 17; Upper padding plate 2 is located on cope match-plate pattern 1; Clamping plate 16 are located on upper padding plate 2; Stripper plate 5 is connected with upper padding plate 2 by heavy-duty springs 4; Guide pillar 3 is connected on clamping plate 16 through stripper plate 5; Essence is rushed punch 15 and is connected on clamping plate 16 through stripper plate 5; Contour screw 17 one end are connected with stripper plate 5, and the other end is connected on clamping plate 16 through cope match-plate pattern 1, upper padding plate 2; Counterdie comprises that essence rushes de-14 in the outer cranse 6 of die, inner ring die 13, lower bolster 7, lower bolster 9, essence punching, pneumatic jack backing plate 12, push rod 11; Lower bolster 7 is connected on lower bolster 9 by pad angle 8; Inner ring die 13 is connected in essence and rushes on the outer cranse 6 of die, and essence is rushed the outer cranse 6 of die and is connected on lower bolster 7; Essence is rushed the outer cranse 6 of die and is provided with pilot hole, and pilot hole is connected with guide pillar 3; In essence punching, de-14 rush the outer cranse 6 of die through lower bolster 7 and essence and are connected on pneumatic jack backing plate 12, and be positioned at essence rush punch 15 under; Pneumatic jack backing plate 12 is between lower bolster 7 and lower bolster 9; Push rod 11 is connected on pneumatic jack backing plate 12 through lower bolster 9; Between pneumatic jack backing plate 12 and lower bolster 9, be provided with spring 10.
It is open circles ring-type that the utility model essence is rushed the outer cranse 6 of die.
The utility model utilizes principle of expanding with heat and contracting with cold that inner ring die 13 is pressed into essence and rushes the outer cranse 6 of die, overcomes essence and cuts the outside tension force of process die and guarantee that concave die cavity is outwards not swollen, guarantees dimensional stability and die service life.
The utility model overcome essence break through journey die be subject to outside tension force make die cavity outward swollen key components and parts be that essence is rushed the outer cranse 6 of die.In Mould Machining process, circular essence being rushed to cranse 6 internal diameters outside die processes less than circular inner ring die 13.Cranse 6 burnings are red outward with acetylene, circular essence to be rushed to die, then with hydraulic press, circular inner ring die 13 are pressed into circular essence and rush the outer cranse 6 of die.Oblong essence is rushed the outer cranse 6 cooling steel material of die and is expanded with heat and contract with cold, and now its internal circular inner ring die 13 has individual internal force.Therefore die has outwards tension force in essence is cut process circle, and circular essence is rushed outer 6 pairs of the cranses of die and is inside contracted power.Two force directions are contrary, just in time cancel out each other.Thereby overcome essence, break through the outside swollen technique bottleneck of journey die, improve die service life and dimensional stability.
During operation, operator first locks the cope match-plate pattern of mould 1 at punch press upper mounted plate, and lower bolster 9 lockings are at punch press bottom plate.Start punch press opening program, open the height stroke that reaches enough.Operating personnel is placed on upper engineering component in essence punching and takes off on 14 locating holes. and start press closes program, make whole patrix: cope match-plate pattern 1, upper padding plate 2, guide pillar 3, heavy-duty springs 4, stripper plate 5, essence are rushed punch 15 and moved downwards.In guide pillar 3 correcting situations, stripper plate 5 is the highest to be encountered essence and rushes the outer cranse 6 of die, heavy-duty springs 4 is compressed, contour screw 17 upwards slides, until heavy-duty springs 4 compressed 8 is after 10mm, essence is rushed punch 15 and is applied and defeats into de-14 in essence punching, is positioned in essence punching the steel backing that brakes on de-14 and cuts through concave-convex mold, because there is tension force outside an elder generation at concavo-convex working angles inner ring die 13, make concave die cavity outwards swollen.And now cuff rushes cranse 6 outside die in the essence of inner ring die 13: rise because of heat and pressed cupping tool in people, have after cooling to inside contracting power.Now the direction of two power is just the opposite, according to mechanics principle, now just cancels out each other.Brake steel backing is pressed into essence and rushes in interior de-14, and essence punching generation waste material is just enclosed within essence and rushes on punch 15.When punch press operation is by lower fulcrum, the steel backing that brakes is deviate from by below cylinder by push rod 11.And stripper plate 5 also thereupon heavy-duty springs 4 restore to the original state and slide downwards.
