Description
Technical field
The invention belongs to field of mechanical technique, relate to the feed mechanism 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 die-casting to form is simple, manufacturing cost is lower.Therefore, fine powder press molding machine is extensive use of in machining.
Supply with a very important step of powder stock to fine powder press molding machine in the die casting workpiece process.In order to improve working (machining) efficiency, realize automation mechanized operation, pay-off is set on fine powder press molding machine gets final product.As a kind of " hopper of adjustable poly-formula " that China Patent No. 92104269.8 provides, it comprises that one is used for the cylinder of feeding and the hopper of the cylinder sidepiece that is connected.Be provided with the feeding spiral rod that links to each other with power section in the cylinder.Powder stock in the hopper just can be carried powder stock by the feeding spiral rod that rotates after in a single day entering in the cylinder, thereby reaches the purpose of self-feeding.
But above-mentioned patent carries the purpose of various different materials to be provided with adjusting device again in order to reach, and its adjusting device comprises a series of parts such as deflector.As can be seen, above-mentioned patent part is too much, and it is complicated that structure seems.Simultaneously, flowing of material mainly is that rotation by screw rod realizes, and the gap between screw rod and the cylinder interior is less, therefore, is easy to take place material in the cylinder stop up, and makes that its stability in use is not high.Certainly, just can must earlier feeding spiral rod be taken out after stopping up in the cylinder, handle comparatively loaded down with trivial details as can be seen.
Summary of the invention
The objective of the invention is at existing in prior technology the problems referred to above, provide a kind of simple in structure, and make the feed mechanism of the higher fine powder press molding machine of fine powder press molding machine job stability.
Purpose of the present invention can realize by following technical proposal: a kind of feed mechanism of fine powder press molding machine; be arranged on the frame of fine powder press molding machine and it is in the diel; it comprises that a top has charging aperture; the bottom has the hopper of discharging opening; it is characterized in that; described feed mechanism comprises that also a bottom has the feed cylinder of feeding port; the sidepiece of feed cylinder communicates with the discharging opening of hopper; and in feed cylinder, be provided with the feeding brush; the feeding brush is made up of shank that links together and bristle portion; shank is connected with first motor, and bristle portion is positioned at the feeding port place.
Diel place that powder stock is delivered to fine powder press molding machine realizes by this feed mechanism.Particularly, the powder stock in charging aperture is sent into hopper can be entered in the feed cylinder by discharging opening, finally makes powder stock enter the feeding port place of feed cylinder, that is to say powder stock is delivered to diel place.
The feeding brush is along with rotation in first motor operation course, powder stock that just can diel place is unnecessary by the bristle portion on it in the feeding brush rotation process is removed, make diel place have an amount of powder stock, the final feasible workpiece size that is processed is unified.
In the feed mechanism of above-mentioned fine powder press molding machine, the discharging opening place of described hopper is provided with the feeding tooth, and the outer end of feeding tooth passes hopper and links to each other with second motor.Just can prevent that by such structure powder stock from stopping up in hopper.Obviously, the powder stock in the hopper is entered in the feed cylinder swimmingly.
In the feed mechanism of above-mentioned fine powder press molding machine, described feeding tooth is made up of body that is strip and tooth bar, and the outer end of body passes hopper and links to each other with second motor, and the tooth bar vertically is connected in the body sidepiece that is positioned at hopper.Under the drive of second motor, this cognition of feeding tooth is along with rotation, and the tooth bar on the body prevents that along with just stirring powder stock in the rotation process powder stock from stopping up in hopper.
In the feed mechanism of above-mentioned fine powder press molding machine, be provided with to the shank outside vertical of described feeding brush the some stirring teeth that are strip.As can be seen, the stirring tooth on it also can be along with rotation in the feeding brush rotation process.The stirring tooth that rotates just can stir the powder stock in the feed cylinder, prevents that powder stock from stopping up in feed cylinder.
In the feed mechanism of above-mentioned fine powder press molding machine, the bottom of described feed cylinder is provided with the sealing gasket that is complementary with its shape.The sealing pad so just makes powder stock can not spill from the feeding port of feed cylinder between feed cylinder and diel.
Compared with prior art, the feed mechanism of this fine powder press molding machine only is made up of hopper, feed cylinder, feeding tooth and feeding brush, and therefore, it is simple in structure, and the manufacturing assembling is comparatively convenient.
Simultaneously, in case after powder stock was sent in the hopper, the stirring tooth that brushes by feeding tooth and feeding can make the powder stock in hopper and the feed cylinder smooth and easy mobile, therefore, the fine powder press molding machine in this feed mechanism is difficult for stopping up.In addition, also can dispose by the powder stock that diel place is unnecessary, make diel place have an amount of powder stock, that is to say that the workpiece size that is processed is unified by the feeding brush.Obviously, adopt its job stability of fine powder press molding machine of this feed mechanism higher.

The specific embodiment
As depicted in figs. 1 and 2, the feed mechanism of this fine powder press molding machine is arranged on the frame of fine powder press molding machine, and it is in the diel of fine powder press molding machine.It is made up of hopper 1, feed cylinder 2, feeding tooth 3 and feeding brush 4 etc.
As Fig. 2 and shown in Figure 4, feeding tooth 3 is located in the hopper 1 and it is positioned at discharging opening 12 places, and feeding tooth 3 is made up of body 31 that is strip and tooth bar 32.The outer end of body 31 passes hopper 1 and is connected with the second motor 5a, and above-mentioned tooth bar 32 is positioned at body 31 sidepieces of hopper 1 with regard to vertical being connected in.
As shown in Figures 2 and 3, feeding brush 4 is located in the feed cylinder 2, and it is made up of shank 41 that links together and bristle portion 42.Shank 41 passes feed cylinder 2 its outer ends and links to each other with first motor 5, and the inner of shank 41 is positioned at feed cylinder 2 and links together with bristle portion 42, and bristle portion 42 is in feeding port 21 places of feed cylinder 2.In the present embodiment, in feed cylinder 2, stop up, stir tooth 43, stir tooth 43 and be strip being connected some of shank outside vertical of feeding brush 4 in order to prevent powder stock.
As depicted in figs. 1 and 2, powder stock makes that under the stirring of feeding tooth 3 powder stock in the hopper 1 is entered in the feed cylinder 2 by discharging 12 places smoothly after sending in the hopper 1 by charging aperture 11; Powder stock in the feed cylinder 2 is difficult for stopping up under the effect of stirring tooth 43, makes powder stock enter feeding port 21 places of feed cylinder 2 swimmingly.Because diel is positioned at the bottom of feed cylinder 2 feeding ports 21, so just make above-mentioned powder stock finally enter to diel place, feeding brush 4 just can be disposed by the powder stock that diel place is unnecessary by the bristle portion 42 on it in rotation process, makes diel place keep an amount of powder stock.The last workpiece size that is suppressed is unified.
In addition, in order to prevent powder stock by spilling between feed cylinder 2 and the diel, between is provided with sealing gasket 6, and the bottom shape of the shape of sealing gasket 6 and feed cylinder 2 is complementary.
