Interior powder is dropped into dosing hole 211 and fills up dosing hole 211, after filling up, then makes storage powder tank 1
Fracture position is moved to, is moved between feed position and fracture position by making storage powder tank 1 so that
In extremely rapid succession being automated to the feeding of dosing hole 211 is carried out, and improves production efficiency.
Further, the powder feeding mechanism includes：
Powder feeding bar 31, as shown in fig. 7, forming some powder feeding holes 311；
Powder feeding baffle plate 35, as shown in figure 8, some powder feeding vias 351 are formed, the powder feeding baffle plate
35 can relatively described powder feeding bar 31 slide so that powder feeding baffle plate 35 have the powder feeding via 351
The charge position misplaced with the powder feeding hole 311 and the powder feeding via 351 and the powder feeding hole 311
The discharge position of alignment；
Powder feeding drive device 34, for driving the powder feeding bar 31 to move, makes the powder feeding hole 311 exist
The lower end of material path 212 receiving the filling position of the powder from the dosing hole 211 and stretch into
To die ontology so that powder is converted between the feeding position of die ontology；
The powder feeding baffle plate 35 is in charge position when the powder feeding hole 311 is located at filling position, described
The powder feeding baffle plate 35 is in discharge position when powder feeding hole 311 is located at feeding position.
Powder feeding hole 311 is preferably bellmouth, and open top is big, and bottom opening is small, to facilitate powder to lead to
Cross powder feeding hole 311.
As shown in figure 8, the shaping of the bottom wall of powder feeding bar 31 is fluted, powder feeding baffle plate 35 is located at can in groove
Moved along groove.
Groove cross section can be stairstepping, trapezoidal etc..
Powder feeding bar 31 can be one, or many be set up in parallel, and be as shown in Figure 3 two
Root, 3,4 etc. can be further arranged to according to actual conditions, and multiple is carried out simultaneously to meet
Feeding during production.
Preferably, the quantitative drive device 42 is servomotor, can be in control using servomotor
The stroke of the quantitative bar 41 of precise control under the control of device, position control is accurate, thus can be with precise control
The volume of dosing hole 211, so as to realize the high-precision control to powder amount.
The confession powder drive device 12, powder feeding drive device 34, the sliding driving device 22 are selected from
One kind in cylinder, hydraulic cylinder and electric cylinders, in order to control.
Preferably, contact of the quantifying board 21 with the base plate 11 and the pedestal 2 each other

It is interior.
The course of work of powder quantitative-feedingdevice device is that quantitative principle is as shown in Figure 2：
Powder feeding baffle plate 35 is adjusted into storage powder via 111 in the fracture position misplaced with dosing hole 211,
Powder is added to storage powder tank 1, because storage powder via 111 misplaces with dosing hole 211, powder cannot
Entered in dosing hole 211 by storing up powder via 111.Quantifying board 21 is driven by sliding driving device 22
Quantitative position is moved to, in quantitative bar 41 is can extend into dosing hole 211, then is filled by quantitative driving
Putting the position of 42 adjustment quantitative bars 41 makes dosing hole 211 form required volume (certain this step
Can also be pre-adjusted).Afterwards, the storage powder tank 1 is driven to move to by for powder drive device 1
Up to feed position, the storage powder via 111 on base plate 11 is set to be aligned with dosing hole 211, powder will be through
Cross storage powder via 111 and fill up the realization of dosing hole 211 quantitatively, after dosing hole 211 is filled, by powder feeding
The regulation of baffle plate 35 is to storage powder via 111 in the fracture position misplaced with dosing hole 211.It is quantitative to drive dress
Put and drive quantitative bar 41 to reach the position concordant with the bottom opening of dosing hole 211, then driven by powder feeding
Device 34 drives powder feeding bar 31 to be in filling position, and powder feeding hole 311 is located at the lower end of material path 212,
Feed powder baffle plate 35 is in charge position, and powder feeding via 351 misplaces with powder feeding hole 311, feed powder baffle plate 35
The bottom of powder feeding hole 311 is blocked, makes powder feeding hole 311 prepare to receive powder.Then, by sliding drive
Dynamic device 22 drives quantifying board 21 to move to lower discharge position, and dosing hole 211 is aligned with material path 212,
During dosing hole 211 just drops into powder feeding hole 311 by material path 212.Afterwards, then by powder feeding drive
Dynamic device 34 drives powder feeding bar 31 to reach feeding position, powder feeding bar 31 is extend into die ontology,
During die ontology is stretched into, blowing position is gone to against promotion powder feeding baffle plate 35 by die ontology
Put, final powder feeding via 351 is aligned with powder feeding hole 311, and powder is by powder feeding in powder feeding hole 311
Hole 351 is fallen into the die cavity of die ontology, completes a feeding.Afterwards, powder feeding bar 31 returns to splicing
Position, during return, under the action of the spring, powder baffle plate 35 returns to charge position, so that
Powder feeding hole 311 can again receive powder.
The powder quantitative-feedingdevice device of above-mentioned Chu Fen mechanisms and powder feeding mechanism is employed, is realized to die ontology
