[0014] A method for preparing a metal ceramic tool preparation device, using the above-mentioned metal ceramic tool preparation device, comprises the following steps: Step 1: The metal powder and ceramic powder to be mixed are put into the mixing barrel through the feeding pipe. The metal powder and ceramic powder entering the mixing barrel fall on the top of the distribution frame under the action of their own gravity. The distribution frame reciprocates longitudinally and rotates to distribute the metal powder and ceramic powder on the top of the distribution frame. At the same time, the curved rod rotates to pre-mix the metal powder and ceramic powder uniformly. Step 2: After the metal powder and the ceramic powder are pre-mixed according to a certain ratio, the mixed metal powder and ceramic powder are put into a high-energy ball mill for secondary mixing; Step 3: After the secondary mixed powder is pressed into the preliminary shape of the tool by molding, the pressed blank is placed in a high temperature furnace for sintering; Step 4: After the pressed blank is sintered, it is cooled and further ground to ensure the accuracy and surface finish of the tool.

[0015] The present invention provides a metal ceramic tool preparation device having the following beneficial effects: (1) The invention drives the dividing frame to move downward and reset by the downward movement of the hollow rod. The dividing frame moves reciprocatingly longitudinally and rotates to divide the metal powder and ceramic powder on the top of the dividing frame. The reciprocating longitudinal movement and rotation of the dividing frame can prevent the metal powder and ceramic powder from accumulating in the local area of ​​the mixing barrel, thereby reducing the possibility of local accumulation and improving the mixing efficiency of the pre-mixing of the metal powder and ceramic powder. The arc panel moves reciprocatingly longitudinally to continuously turn over the metal powder and ceramic powder at the bottom of the mixing barrel. The reciprocating motion of the arc panel can effectively break the hierarchical structure and aggregation phenomenon between the powders, helping the metal powder and ceramic powder to be evenly distributed, thereby maintaining the fluidity and pre-mixing effect of the powder.

[0016] (2) In the present invention, the gear generates rotation to drive the stirring rod to rotate the tooth block upward to extrude the driving gear to rotate. The gear generates rotation to drive the stirring rod to rotate. The stirring rod rotates to break up the agglomerated powder inside the feed tube. Breaking up the agglomerates by the stirring rod can promote the uniform distribution of the powder and enhance the subsequent pre-mixing effect of the metal powder and the ceramic powder. The elastic telescopic rod generates vibration to drive the driving rod to vibrate. The driving rod vibration drives the stirring rod to resonate together. The resonance of the stirring rod can more effectively reduce the agglomeration of powder, ensure the uniform distribution of powder, and further enhance the breaking effect of the stirring rod.

[0017] (3) In the present invention, the cross rubber valve is squeezed by the dispersant inside the conduit. The cross rubber valve is deformed by the squeezing of the dispersant entering the conduit. The deformation of the cross rubber valve releases the seal of the conduit. After the seal of the conduit is released, the quantitative dispersant at the bottom of the square frame enters the mixing barrel through the conduit to mix with the metal powder and the ceramic powder. The dispersant can reduce the mutual adhesion between the metal powder and the ceramic powder and prevent the formation of agglomerations or lumps between the particles, thereby making the powder easier to be evenly distributed during the pre-mixing process. In addition, the quantitative addition of the dispersant can ensure that the amount of the dispersant is within the optimal range, thereby obtaining a better dispersion effect.
