Abstract
The invention relates to a powder feeding device for a powder hydraulic machine. The powder feeding device comprises a guide rail and a feeding cylinder which are fixedly arranged on a product support plate, a feeding bracket slidably arranged on the guide rail, and a feeding box fixedly arranged on the feeding bracket, wherein the feeding bracket is fixedly connected with the push rod end of the feeding cylinder; the powder feeding device is characterized in that: the feeding box is vertical to a vibration air cylinder fixedly arranged on the side wall of the guide rail; the push rod end of the vibration air cylinder is fixedly connected with a vibration gate; and the vibration gate is positioned in the feeding box. By adopting the vibration air cylinder and the vibration gate, the vibration air cylinder pushes the gate to vibrate back and forth during filling of powder raw materials into a die cavity; therefore, the powder raw materials can fall into the cavity uniformly, the filling uniformity of the powder raw materials can be ensured, and the subsequent compression molding is facilitated.
Description
Technical field
The present invention relates to the dust feeder of powder hydraulic press.
Background technology
Dust feeder is in the powder hydraulic press powder stock to be transported to necessary structure the mold cavity from hopper, at present, dust feeder commonly used by be fixed on guide rail and feeding cylinder on the goods gripper shoe, be slidingly mounted on the stock support on the guide rail, the feed box that is installed on the stock support constitutes, the push rod end of feeding cylinder is fixedlyed connected with stock support.When feeding, the feeding cylinder promotes stock support and moves to the feeding mouth place of mold cavity along guide rail, and powder stock falls in the die cavity in the effect of self gravitation, drives under feed box moves back and forth at the feeding cylinder, powder constantly can be filled in the die cavity, realizes the dress powder.Above-mentioned dust feeder has simple in structure, the characteristics of easy operating, but be subjected to the influence of powder stock self flowability, when pressing structure complexity or the high tube kind part of thin-walled, cause powder stock to fill irregular problem easily, and then influence follow-up compression moulding.
Summary of the invention
The present invention provides a kind of simple in structure, easy to operate for solving the technical problem that exists in the known technology, improves the dust feeder that powder stock is filled the powder hydraulic press of the uniformity.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of dust feeder of powder hydraulic press, comprise the guide rail and the feeding cylinder that are packed on the goods gripper shoe, be slidingly mounted on stock support on the guide rail, be packed in the feed box on the stock support, the push rod end of feeding cylinder is connected on the stock support, it is characterized in that: install the vibration cylinder on the sidewall of described feed box perpendicular to guide rail, the push rod end of vibration cylinder is fixed with vibrating grid, and described vibrating grid is positioned at feed box.
Advantage and good effect that the present invention has are:
Adopt above-mentioned vibration cylinder and vibrating grid, powder stock is being filled in the process of mold cavity, the vibration cylinder promotes the vibrating grid double vibrations, and powder stock is evenly fallen in the die cavity, has guaranteed the uniformity that powder stock is filled, and is convenient to follow-up compression moulding.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an A-A cutaway view among Fig. 1.
Among the figure: 1, goods gripper shoe; 2, guide rail; 3, feeding cylinder; 4, stock support; 5, feed box; 6, vibration cylinder; 7, vibrating grid; 7-1, frame part; 7-2, grizzly bar.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and 2, a kind of dust feeder of powder hydraulic press, comprise the guide rail 2 and the feeding cylinder 3 that are packed on the goods gripper shoe 1, be slidingly mounted on the stock support 4 on the guide rail, be packed in the feed box 5 on the stock support, the push rod end of stock support and feeding cylinder is connected, be fixed with vibration cylinder 6 on the sidewall of described feed box perpendicular to guide rail, the push rod end of vibration cylinder is fixed with vibrating grid 7, described vibrating grid is positioned at feed box, concrete, vibrating grid is made of the frame part 7-1 that is connected in the vibration cylinder and several parallel grizzly bar 7-2 that are welded on the framework steel plate and steel bar welding fabrication.
Operation principle of the present invention:
Powder stock in the outside hopper enters feed box by soft pipeline, when press begins to carry out the feeding action, at first the feeding cylinder stops feed box being shifted onto the feeding mouth place of mold cavity along guide rail after, vibrate cylinder then and begin to drive the round vibration of vibrating grid, simultaneously each stamping of mould moves to predetermined location under the effect of driving cylinder separately, in said process, powder stock evenly flows in the material chamber that is formed by each stamping motion by vibrating grid, after each stamping moves to assigned address, stop behind the vibrating grid time-delay vibration certain hour, powder is filled and is finished, at this moment, the single-piece feeding is finished, and the feeding cylinder drives feed box and returns initial position, prepares the next feeding action of beginning.
To sum up, the present invention adopts said structure, powder stock is being filled in the process of mold cavity, and the vibration cylinder promotes the grid double vibrations, and powder stock is evenly fallen in the die cavity, has guaranteed the uniformity that powder stock is filled, and is convenient to follow-up compression moulding.
