Abstract
The utility model discloses a fan plate flanging die positioned outside a wind driven generator, comprising an upper die base, a lower die base, concave dies, a convex die, a lower discharging plate and an upper discharging plate, wherein the concave die and the convex die are arranged between the upper die base and the lower die base; the concave die is connected to the lower end of the upper die base through a cylindrical pin and a screw; the convex die is connected to the upper end of the lower die base through the cylindrical pin and the screw; the upper discharging plate is connected between the concave dies; the lower discharging plate is connected at the outer side of the convex die; and the convex die is a guide type convex die and is provided with a seam allowance of a positioning workpiece blank and a positioning disc. The fan plate flanging die has the advantages of capability of improving workpiece quality and work efficiency, little fan laterality, good appearance quality, few process, complex die punching blanking, complex die flanging molding, obviously-shortened processing time of a single workpiece, cost and raw material saving, processing cost saving without blanking again outside a fan plate, and suitability for batch production.
Description
Technical field
The utility model relates to cold punching die, relates in particular to a kind of wind-driven generator external fan plate flange die.
Background technology
Traditional processing mode, fan board adopts oxygen-acetylene cutting, lathe turning cylindrical, hole, lining; Oxygen-acetylene cutting is adopted in the fan board outer, the pincers worker shaping, and welding fan board finished product, operations such as type are repaiied in polishing, waste time and energy, and the process-cycle is long; Fan board adopts Welding Structure, and workpiece quality is relatively poor, and fan is laid particular stress on bigger; After the fan board blanking, the fan board outer is blanking again also, the waste raw material.
The utility model content
The purpose of this utility model provides the multiple film punching and blanking of a kind of need, film flange one-shot forming two procedures is finished the wind-driven generator external fan plate flange die of processing again.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of wind-driven generator external fan plate flange die, comprise upper bolster, die shoe, die, punch, following stripper and loading and unloading material plate, die and punch are arranged between upper bolster and the die shoe, die is connected in the upper bolster lower end by straight pin and screw, punch is connected in the die shoe upper end by straight pin and screw, the loading and unloading material plate is connected between the die, following stripper is connected in the punch outside, described punch is the guide type punch, punch is provided with the seam of location workpiece blank, also is provided with positioning disk on the punch.
It is 0.5 ° angle of inclination that described die inwall is set to gradient.
The advantage of the utility model wind-driven generator external fan plate flange die design is:
(1) improve workpiece quality, fan is laid particular stress on little, and apparent mass is good.
(2) increase work efficiency, operation is few, multiple stamping hole blanking, multiple mould flange moulding, and the single-piece work time is obviously reduced weak point, has significantly improved production efficiency.
(3) save cost, save raw material, the fan board outer does not need blanking again, saves processing
Expense, operation is few, the efficient height, processing charges is few, is fit to produce in batches.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model wind-driven generator external fan plate flange die mould installation diagram;
Fig. 2 is the utility model wind-driven generator external fan plate flange die punch structure figure;
Fig. 3 is the utility model wind-driven generator external fan plate flange die mould closure state schematic diagram;
Fig. 4 the utility model wind-driven generator external fan plate flange die workpiece figure.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the mould structure of novel wind generator external fan plate flange die comprises upper bolster 1, straight pin 2, die 3, following stripper 4, punch 5, screw 6, knockout plate 7, screw rod 8, following knockout plate 9, hex nut 10, studs 11, buffer 12, packing ring 13, discharging screw 14, straight pin 15, die shoe 16, positioning disk 17, screw 18, loading and unloading material plate 19, screw 20, screw 21, buffer 22, studs 23, hex nut 24, screw rod 25, following knockout plate 26, packing ring 27, knockout plate 28, die 3 and punch 5 are arranged between upper bolster 1 and the die shoe 16, die 3 is connected in the upper bolster lower end by straight pin 2 and screw 21, punch 3 is connected in die shoe 16 upper ends by straight pin 15 and screw 6, loading and unloading material plate 19 is connected between the die 3, following stripper 9 is connected in punch 5 outsides, punch is the guide type punch, punch is provided with the seam of location workpiece blank, punch is provided with positioning disk 17, shown in Figure 3, wherein A is arranged to 0.5 ° gradient for this die inwall in the place, and the B place is a workpiece; Shown in Figure 2, the C place is a workpiece blank among the figure, and the D place is a workpiece precompressed height, and the E place is a workpiece prestretched height, and this workpiece precompressed highly is 5mm, and the workpiece prestretched highly is 12mm.
The fan board height 30mm of wind-driven generator external fan plate flange die of the present utility model, the flange height is bigger, the general long guide type punch of prestretched that adopts, mold stroke is also longer, has increased the seam of location workpiece blank on punch, also design the simple die positioning disk and (omitted guider, after mould is installed on the hydraulic press, just unload positioning disk), simplified mould structure, a whole set of The mould features compact structure, mold stroke is shorter; The die inwall has adopted the band gradient in addition, and vertical design has been adopted in the punch outer, has both guaranteed that the workpiece side wall energy enough keeps vertically, can make things convenient for the workpiece bullet discharging that falls in the die smoothly again.
The concrete course of work of this wind-driven generator external fan plate flange die design is: mould unloads positioning disk after being installed on the hydraulic press, and workpiece blank is placed on punch stop portion (holding workpiece blank by following stripper); Counterdie is up, earlier with workpiece precompressed 5mm, enters the prestretched stage then, and prestretched highly is 12mm; Counterdie is advanced into the flange stage on continuing, and after the mould closure, flange is finished; Counterdie is descending, and mould is opened, and stripper ejects workpiece in mold cavity up and down, machines.
