Preferably, described piercing punch by bolted on described cope match-plate pattern.
Compared with prior art, edge-cutting and hole-punching hole flanging one-time-shaped mould of the present invention by arranging die and hole flanging red needle on described patrix, and concave-convex mold and mating holes be set on described counterdie, make mould disposablely to basin frame, to carry out edge-cutting and hole-punching hole flanging, thereby reduce the operation of production, simultaneously can also guarantee to need the accuracy of stamping-out position, can rapid shaping, improved production efficiency and product quality; And utilize cutting knife can solve the problem of labor cleaning's waste material.
By following description also by reference to the accompanying drawings, it is more clear that the present invention will become, and these accompanying drawings are used for explaining embodiments of the invention.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of edge-cutting and hole-punching hole flanging one-time-shaped mould of the present invention.
Fig. 2 is that basin is put up the schematic diagram after type.
The specific embodiment
With reference now to accompanying drawing, describe embodiments of the invention, in accompanying drawing, similarly element numbers represents similar element.
Please refer to Fig. 1-2, edge-cutting and hole-punching hole flanging one-time-shaped mould of the present invention comprises counterdie and the patrix cooperatively interacting.Wherein, described counterdie comprise lower bolster 1, be arranged on described lower bolster 1 top concave-convex mold 2, be arranged on the cutting knife 3 in described concave-convex mold 2 outsides, the keeper 5 that is arranged on the mesopore die 4 in described concave-convex mold 2 and is arranged on described concave-convex mold 2 tops.Described concave-convex mold 2 is provided with mating holes 2a.Described keeper 5 outsides that stretch through out, the upper end of described mesopore die 4.
Described patrix comprises cope match-plate pattern 6, be arranged on the upper padding plate 7 of described cope match-plate pattern 6 belows, be arranged on the fixed head 8 of described upper padding plate 7 belows and be arranged on the die 9 corresponding with described cutting knife 3 of described fixed head 8 belows.The center of described upper padding plate 7 is provided with the piercing punch 10 corresponding with described mesopore die 4, and described piercing punch 10 is fastened on described cope match-plate pattern 6 by bolt 10a.The center of described fixed head 8 is provided with stripper 11, and the lower end of described stripper 11 is stretched in described die 9, and the lower end of described piercing punch 10 is stretched in described stripper 11.The hole flanging red needle 12 corresponding with described mating holes 2a that is positioned at described piercing punch 10 sides is also installed on described upper padding plate 7, and the lower end of described hole flanging red needle 12 stretches through out outside described stripper 11.Described patrix also comprises link plate 13 and the link plate backing plate 14 that is arranged on described link plate 13 belows, and described link plate backing plate 14 is arranged on the top of described cope match-plate pattern 6.Described hole flanging red needle 12 is 4 grades of red needles, and intensity is higher, and while guaranteeing stamping-out, hole flanging red needle 12 is not easily broken.
