Abstract

The invention relates to the technical field of dies and discloses an inner and outer periphery fine blanking die. The inner and outer periphery fine blanking die comprises an upper die, a lower die, an outer periphery fine blanking component, an inner periphery fine blanking component and a discharging component. The outer periphery fine blanking component comprises an outer periphery concave die and a concave-convex die, and the outer periphery concave die and the concave-convex die are matched with each other; the inner periphery fine blanking component comprises a mesopore convex die arranged in the outer periphery concave die, and the mesopore convex die is matched with the inner wall of the concave-convex die; the discharging component comprises an upper discharging plate embedded between the outer periphery concave die and the mesopore convex die, and the upper discharging plate is capable of vertically sliding along the inner wall of the outer periphery concave die and the outer wall of the mesopore convex die. Due to the facts that the outer wall of the concave-convex die serves as a convex die for outer periphery fine blanking and the inner wall of the concave-convex die serves as a concave die for inner periphery fine blanking, functions of two dies for fine blanking can be completed by mounting only one concave-convex die on the lower die, and accordingly parts are effectively reduced, and simple structure and low die manufacturing cost are achieved. Further, the inner and outer periphery fine blanking die has the advantage of high processing precision.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult Fig. 1, shown in Fig. 2, a kind of inside and outside circle fine blanking die provided by the invention, comprise upper die and lower die, on, between counterdie, be provided with for the cylindrical essence of essence punching to foreign round and rush assembly, cylindrical essence is rushed assembly middle part and is also provided with for the inner circle essence of inner circle essence punching is rushed to assembly, cylindrical essence is rushed assembly and inner circle essence and is rushed and between assembly, be also provided with a discharge component, cylindrical essence is rushed assembly and is comprised the outer cupping tool 3 being connected with cope match-plate pattern 1 by upper padding plate 2, also comprise a concave-convex mold 8 being connected with lower bolster 5 by lower bolster 10, outer cupping tool 3 matches with concave-convex mold outer wall 81, inner circle essence is rushed assembly and is comprised that one is arranged at the mesopore punch 7 that outer cupping tool 3 is inner and be connected with upper padding plate 2, mesopore punch 7 matches with concave-convex mold inwall 82, discharge component comprises and is embedded the loading and unloading material plate 6 between cupping tool 3 and mesopore punch 7 outside, loading and unloading material plate 6 can slide up and down along outer cupping tool inwall 31 and mesopore punch outer wall 71.The present invention rushes assembly and inner circle essence by cylindrical essence and rushes assembly and shear part inside and outside circle, discharge component is used for making fabricated part to release from mould, and pass through the outer wall of concave-convex mold 8 as the punch of cylindrical essence punching, the inwall of concave-convex mold 8 is as the die of inner circle essence punching, on counterdie, only need the effect that a concave-convex mold 8 can complete two moulds of essence punching is installed, effectively reduced number of spare parts, simple in structure, die manufacturing cost is low, and has advantages of that the precision of processing is high.In use, cope match-plate pattern 1 can be connected by screw with stamping machine, between cope match-plate pattern 1, upper padding plate 2, outer cupping tool 3, mesopore punch 7, can connect by bolt or screw, and loading and unloading material plate 6 can be connected with the discharge arm of stamping machine by connecting rod.Between upper die and lower die, also can arrange when stripper 4 is on the one hand for original state and place blank, also can eject the waste material after processing on the other hand.
In the present embodiment, on concave-convex mold inwall 82, the position on top is higher than top on concave-convex mold outer wall 81, and the position on 71 times tops of mesopore punch outer wall is lower than the lower top of outer cupping tool inwall 31.While being so arranged on patrix down stroke, on concave-convex mold inwall 82, first the 71 times tops in top and mesopore punch outer wall contact, be that inner circle essence is rushed the assembly essence of first working and rushed endoporus, patrix continues down stroke, on concave-convex mold outer wall 81, the 31 times tops in top and outer cupping tool inwall contact, and cylindrical essence is rushed the assembly outer hole of essence punching of working again.Make inside and outside circle in the punching of different time essence, smart impulse force can reduce to approach half, and capacity usage ratio is high.
In the present invention, outer cupping tool inwall 31 is provided with circle first projection 32, and loading and unloading material plate 6 outer walls are provided with circle second projection 61, the first projections 32 and coordinate loading and unloading material plate 6 descending spacing with the second projection 61.After the punching of inside and outside circle essence finishes, patrix is up, upper and lower mould departs from, but finished parts cannot come off because frictional force is embedded in the space between mesopore punch 7 and outer cupping tool 3, ejector beam action top in stamping machine is stripper 6 upwards, and loading and unloading material plate 6 ejects finished parts and realizes discharging from space.By the mating reaction of first projection the 32 and second projection 61, loading and unloading material plate 6 can not come off in space.
Preferably, concave-convex mold is connected with lower bolster 10 by a bottom plate 9, on bottom plate 9, be also arranged with an adjusting ring 11, adjusting ring 11 is connected with lower bolster 5, adjusting ring 11 is circumferentially evenly equipped with 4 screwed holes 12, the axis of screwed hole 12 radially overlaps with bottom plate 9, is equipped with an adjustment screw 13 in each screwed hole 12.When patrix and counterdie do not have centering, or while having a little bias.By regulating the adjustment screw 13 of adjusting ring 11 surroundings, adjustment screw 13 holds out against bottom plate 9, makes bottom plate 9 have small displacement, finally regulates concave-convex mold 8 and patrix centering in bottom plate 9.
Although described by reference to the accompanying drawings working of an invention mode; but the patent owner can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present invention, all should be within protection scope of the present invention.
