Description
Technical field
The utility model belongs to field of mechanical technique, relates to the pay-off of a kind of fine powder press molding machine, particularly 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.
Usually, the die cavity in the fine powder press molding machine is arranged on the table top, in case powder stock send in the die cavity, more just can be with the workpiece press forming by the staking punch that presses in the die cavity.
For powder stock is sent in the die cavity easily, people have designed various pay-offs.As a kind of " the powder tube of adjustable poly-formula " that China Patent No. 92104269.8 provides, it comprises that one is used for the cylinder of feeding and the powder tube 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 powder tube 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 purpose of this utility model is at existing in prior technology the problems referred to above, provides a kind of stability in use good, the pay-off of fine powder press molding machine simple in structure.
The purpose of this utility model can realize by following technical proposal: a kind of pay-off of fine powder press molding machine; be arranged on the mold work platform of fine powder press molding machine; has die cavity on the mold work platform; the top of die cavity has staking punch moving up and down; it is characterized in that; be provided with powder feeder and powder tube on the described mold work platform from the bottom to top successively; powder feeder can drive it and links to each other along the drive unit that the mold work platform moves back and forth with one, and the powder tube is connected on the mold work platform and the powder tube is positioned at the sidepiece of staking punch.
By drive unit powder feeder is moved along the mold work platform, thereby powder feeder is in over against the die cavity or the position of departing from die cavity.Obviously, when powder feeder during over against die cavity, the powder stock in the powder feeder will enter in the die cavity, thereby finishes feeding.Treat that powder feeder oppositely moves when being in the position of departing from die cavity, staking punch presses in the die cavity, just can be with workpiece compression moulding.
Simultaneously, the powder feeder feeding is realized by the powder tube.Particularly, powder stock is added in the powder tube, the powder stock in the powder tube is entered in the powder feeder by meal outlet.
The powder tube is fixed, and powder feeder moves back and forth.Obviously, storing is realized by the powder tube, and the effect of powder feeder just is used for powder stock is delivered in the die cavity.Such structure makes that the powder feeder size is less, makes that the spacing between staking punch and the mold work platform is less, makes that accordingly staking punch can be fast with workpiece compression moulding.
In the pay-off of above-mentioned fine powder press molding machine, described drive unit comprises a cylinder that is fixed on the mold work platform, and above-mentioned powder feeder is fixed on the piston rod top of cylinder.Piston rod is moved, and piston rod moves and just can drive powder feeder and move.
As another scheme, in the pay-off of above-mentioned fine powder press molding machine, described drive unit comprises a hydraulic cylinder that is fixed on the mold work platform, and above-mentioned powder feeder is fixed on the piston rod top of hydraulic cylinder.Piston rod is moved, and piston rod moves and just can drive powder feeder and move.
As the third scheme, in the pay-off of above-mentioned fine powder press molding machine, described drive unit comprises a motor that is fixed on the mold work platform, the rotating shaft sidepiece of above-mentioned powder feeder fixed electrical machinery.Rotating shaft is rotated, and rotating shaft is rotated just can drive the powder feeder swing.
In the pay-off of above-mentioned fine powder press molding machine, be provided with rotating impeller in the described powder feeder.Make the powder stock in the powder feeder to flow smoothly by impeller, can blockage phenomenon.
In the pay-off of above-mentioned fine powder press molding machine, the meal outlet place of described powder tube is provided with the material controlling mechanism that meal outlet can be opened or closed.Need make the interior powder stock of powder tube enter the interior operation of powder feeder material controlling mechanism gets final product.
In the pay-off of above-mentioned fine powder press molding machine, described material controlling mechanism is a piston and hydraulic cylinder, and meal outlet place and piston that piston is in the powder tube are connected mutually with the piston rod of hydraulic cylinder.Just can drive piston by piston rod in the hydraulic cylinder course of action and move, when piston was blocked the meal outlet of powder tube, the powder stock in the powder tube just can not fall in the powder feeder.When moving back and forth under the effect of piston piston at hydraulic cylinder, just the powder stock at meal outlet place can be pushed in the powder feeder.
Compared with prior art, the pay-off of this fine powder press molding machine is by powder tube storing, and by the powder feeder feeding, such structure makes that the powder feeder size is less, makes that spacing is less between staking punch and the mold work platform.That is to say that staking punch can press in the die cavity fast when the compacting workpiece.Obviously, its operating efficiency is higher.
Simultaneously, also make powder stock to flow smoothly, the powder stock in the powder tube is entered in the powder feeder by material controlling mechanism by the impeller in the powder feeder.Obviously, its stability in use is higher, easy to use.
