Description
Technical field
The invention belongs to field of mechanical technique, relate to the pay-off of a kind of fine powder press molding machine, particularly a kind of fine powder press molding machine.
Background technology
Its manufacturing process of workpiece that adopts powder stock die casting to form is simple, manufacturing cost is lower.Therefore, fine powder press molding machine is extensive use of in machining.
Usually, fine powder press molding machine comprises a mould and is positioned at the staking punch on mould top that staking punch presses down can be with the powder stock compression moulding at mould place.
For making things convenient for feeding, in feed cylinder, be provided with the agitating device that is used to stir powder stock, though make powder stock in feed cylinder, to pass through smoothly like this, but the amount of powder stock can't be controlled, still can make part powder stock hematocrit for block owing to having too much powder stock in it in the feed cylinder.Obviously, be block powder stock and can influence feeding stability.
Simultaneously, the discharging opening place gathers too much powder stock and also is difficult for entering in the forming cavity of mould, can not guarantee that the discharging opening place is always an amount of powder stock, thereby makes the workpiece size disunity that processes, and influences its yield rate.
Summary of the invention
The objective of the invention is at existing in prior technology the problems referred to above, the pay-off of a kind of feeding stability height, fine powder press molding machine simple in structure is provided.
Purpose of the present invention can realize by following technical proposal: a kind of pay-off of fine powder press molding machine; comprise a feed cylinder and a turning cylinder; the inner of turning cylinder is positioned at feed cylinder; the outer end of turning cylinder passes feed cylinder and motor links; the bottom of feed cylinder has discharging opening; it is characterized in that described turning cylinder the inner is fixed with material scraping plate in the form of sheets, discharging opening place and material scraping plate that material scraping plate is positioned at feed cylinder are connected and the turning cylinder sidepiece by connecting rod is parallel.
In the pay-off of above-mentioned fine powder press molding machine, the distance at described material scraping plate one end and feed cylinder center is greater than the distance at the material scraping plate other end and feed cylinder center.
In the motor operation course, drive the material scraping plate rotation by turning cylinder.Just can make in the material scraping plate rotary course that feed cylinder discharging opening place powder stock is even.
Because have a determining deviation between material scraping plate and the turning cylinder, material scraping plate is along with just making powder stock concentrate on the center of discharging opening in the turning cylinder rotation process.That is to say, make powder stock just be in place, mould molding hole.
In the pay-off of above-mentioned fine powder press molding machine, described material scraping plate is curved, and its arc protrusion place is right against the feed cylinder inboard.Such shape makes the interior recess energy product of material scraping plate gather a certain amount of powder stock, thereby makes feed cylinder discharging opening place have an amount of powder stock all the time.
In the pay-off of above-mentioned fine powder press molding machine, the inner place of described turning cylinder also is fixed with material separating disc in the form of annular discs, have the gap between material separating disc and the feed cylinder inboard, and material separating disc is in the top of material scraping plate.Powder stock in the feed cylinder at first can enter material separating disc top when entering discharging opening on it, enters the material separating disc bottom by the gap between material separating disc and the feed cylinder inboard again at powder stock under the gravity effect, promptly enters the material scraping plate place.
In the pay-off of above-mentioned fine powder press molding machine, be provided with to the upper vertical of described material separating disc the some flour material teeth that are column.Material separating disc is along with in the turning cylinder rotation process, and the flour material tooth on the material separating disc also can be along with material separating disc rotates, and smashes thereby the flour material tooth by motion will gather to the powder stock of bulk.
Certainly, the powder stock after smashing just can be entered the material separating disc bottom by above-mentioned gap location.
In the pay-off of above-mentioned fine powder press molding machine, described turning cylinder the inner vertically is fixed with the some stirring teeth that are strip from top to bottom.
In the turning cylinder rotation process, stirring tooth can be along with rotation, thereby by the stirring tooth that rotates powder stock is passed through smoothly in feed cylinder.
Compared with prior art, the pay-off of this fine powder press molding machine at first can will gather to the powder stock of bulk by flour material tooth and smash, and the powder stock after smashing could enter the material scraping plate place through the gap between material separating disc and the feed cylinder inboard.Make that under the effect of material scraping plate the powder stock at discharging opening place is moderate.Obviously, the pay-off feeding stability of this fine powder press molding machine is higher, thereby can process the unified workpiece of size.
In addition, this device just is made up of turning cylinder, material separating disc, material scraping plate etc., and is therefore simple in structure, cost is lower, has advantages of high practicability.

Fig. 3 be this fine powder press molding machine pay-off look up structural representation.
Among the figure, 1, feed cylinder; 11, discharging opening; 2, turning cylinder; 3, material separating disc; 4, material scraping plate; 5, stir tooth; 6, motor; 7, flour material tooth 8, connecting rod.
The specific embodiment
As depicted in figs. 1 and 2, the pay-off of this fine powder press molding machine comprises that is a feed cylinder 1 cylindraceous, and the bottom of feed cylinder 1 has discharging opening 11.
This device also comprises a turning cylinder 2, and the inner of turning cylinder 2 is positioned at feed cylinder 1, and the top of feed cylinder 1 is stretched out in the outer end of turning cylinder 2, and the outer end of turning cylinder 2 is connected mutually with the rotating shaft of motor 6.Certainly,, reach multiple rotating speed, between motor 6 rotating shafts and turning cylinder 2, also variable speed drive can be set in order to make turning cylinder 2 according to actual conditions.
The inner of turning cylinder 2 is fixed with material separating disc 3 and material scraping plate 4 from top to bottom respectively, also vertically from top to bottom in the inner of turning cylinder 2 be fixed with some and stir teeth 5, that is to say to have the tooth 5 of stirring on the turning cylinder 2 on material separating disc 3 tops, also have the tooth 5 of stirring on the turning cylinder 2 of the bottom of material separating disc 3.
As shown in Figures 2 and 3, material separating disc 3 is in the form of annular discs, and the upper surface of material separating disc 3 vertically is fixed with some flour material teeth 7, and material separating disc 3 has the gap of passing through for powder stock with feed cylinder 1 inboard.
In the feeding process, the powder stock in the feed cylinder 1 at first enters the top of material separating disc 3.In motor 6 operation process, drive material separating disc 3, stir tooth 5 rotations by turning cylinder 2.
Make powder stock in feed cylinder 1, pass through smoothly in stirring tooth 5 rotation processes, the powder stock that gathers to bulk can be smashed by the flour material tooth 7 on it in material separating disc 3 rotation processes.Then, powder stock enters material separating disc 3 bottoms by the gap between material separating disc 3 and feed cylinder 1 inboard again, and the material scraping plate 4 that rotates along with turning cylinder 2 accumulates in powder stock at the middle part of feed cylinder 1 discharging opening 11 then.That is to say, make powder stock just be in the top in mould molding hole.
