See also shown in Figure 7ly, it comprises the following steps: for using the preferred embodiment of powder compacting shape machine with embedded metal coil 1 of the present invention with the method for moulding inductor
A. provide one first powder feeding machine to promote to be seated in the first powder feeding box on the exterior sheathing, the first powder feeding box is moved horizontally on exterior sheathing, and will send the powder in first powder box to insert the interior following die tip of external mold die cavity downwards.
B. put above the powder of a coil in the external mold die cavity.
C. move down stacking pedestal, dividing plate and second dust feeder, make the pressure section of base bottom be pressed on the two ends of coil, and in second opening of the downward powder filler of the second powder feeding box that makes second dust feeder to the dividing plate.
D. the second powder feeding machine with second dust feeder pulls back second powder feeding box and the flashboard, make first opening of pedestal, second opening of dividing plate, the 5th opening of flashboard and the 4th opening vertical communication of second powder feeding box below, the powder in second opening is inserted in first opening of pedestal, and cover the top of coil, and dash in moving down, with punch forming one inductance.
E, the pedestal that moves up, dividing plate, second dust feeder and Nei Chong, and external mold is moved down with respect to counterdie, so that the inductance of moulding protrudes outside, the surface of counterdie.
See also Fig. 2, shown in Figure 8, first road in a step is filled out in the powder program, be that the plug 41 of counterdie 4 is fixed in the die cavity 321 of external mold 32, upwards promote external mold 32 with first power unit 23, and upwards promote the push rod (42,43) of counterdie 4 both sides with second power unit 24, to move up with respect to plug 41 respectively, make to form a depression 44 between the top of plug 41 and the both sides push rod (42,43), to hold the Magnaglo that the first powder feeding box 51 is inserted downwards.And as shown in Figure 9, coil 7 sizes in the b step just can be seated in counterdie 4 tops in external mold 32 die cavitys 321, to be pressed on the top of powder.Behind coil 7 location, the patrix 6 in the c step moves down via the driving of the 3rd power unit 25, so that the pressure section 611 of pedestal 61 bottoms is pressed on the electrode 71 at coil 7 two ends (as shown in figure 10).And when the second powder feeding box 632 is pushed ahead, because the 4th opening 638 of the second powder feeding box, 632 belows is communicated with second opening 621 of dividing plate 62, then can makes the powder decline in the second powder feeding box 632 and be filled in second opening 621 interior (shown in the 11st figure) of dividing plate 62.
See also Fig. 2, Figure 12, shown in Figure 13, the d step is that powder and punching press program are filled out in second road of the present invention, wherein, when the second powder feeding machine 631 of second dust feeder 63 pulls back the second powder feeding box 632 with flashboard 633, the 3rd opening 637 of the 5th opening 6331 of flashboard 633 and the second powder feeding box, 632 belows synchronously backward, dividing plate 633 will intercept the supply of powder, and make first opening 614 of pedestal 61, the 5th opening 6331 of flashboard 633, the 4th opening 638 vertical communications of second opening 621 of dividing plate 62 and the second powder feeding box 632, powder in second opening 621 are descended and insert in first opening 614, and cover the top of coil 7.At this moment, because first, five, two, four openings (614,6331,621,638) form a square pipe tunnel, can dash 64 and pass described pipeline for interior, above the powder of punching press in first opening 614, external mold 32 is moved down by the driving of first power unit 23 then, pressurize the simultaneously powder of coil 7 tops and below makes powder coat coil 7 fully, and moulding one inductance 8.
See also Fig. 1, shown in Figure 14 again, moving back in the mould program of e step, after an inductance 8 moulding, power control unit 21 is the starts of control first, second and third power unit (23,24,25), so that the pedestal 61 of patrix 6, dividing plate 62, second dust feeder 63 and interior dashing on 64 are moved, and the push rod (42,43) of external mold 32 and counterdie 4 both sides moves down and returns original position, thereby the inductance 8 of moulding is protruded outside, the surface of counterdie (32,4).
See also shown in the 15th figure, when above-mentioned procedure of processing is finished, and the powder program is filled out in first road that repeats a step, so that the powder in the first powder feeding box 51 are when inserting counterdie 4 tops in external mold 32 die cavitys 321 downwards, the push rod 515 of the first powder feeding box, 51 1 ends will be released the inductance 8 after the moulding simultaneously forward, to concentrate in the charge box (not shown).
Therefore, the present invention has following advantage:
1, the present invention exports the mode of powder respectively by two dust feeders, with extrusion forming one inductance, can effectively reduce the quantity of mould, reduces manufacturing cost.
2, the present invention with the extrusion forming inductance, not only can accelerate the speed of production of inductance by successional mechanical action, and can make inductance one-body molded, to improve the quality.
In sum, hold according within above disclosing, the present invention really can reach the intended purposes of invention, providing a kind of can not only reduce production costs, effectively accelerate the speed of production of inductance, and can make inductance one-body molded, with powder compacting shape machine with embedded metal coil that improves the quality and the method for using described powders compression make-up machine with moulding inductor, have the value of utilizing on the industry, propose application for a patent for invention in accordance with the law.
The above only is preferred embodiment of the present invention, only is illustrative for the purpose of the present invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes to it in the spirit and scope that claim of the present invention limited, revise, even equivalence, but all will fall within the scope of protection of the present invention.
