Description

Technical Field

[0001] The utility model relates to the technical field of ceramic products, in particular to a ceramic grading wheel static pressure forming press. Background Art

[0002] At present, grading impellers are mainly used in domestic nano-level chemical powder grading equipment. Coarse-grained chemical powders are affected by the strong centrifugal force field generated by the high-speed rotation of the grading impeller in the grading area, so as to screen out nano-level chemical powders. As a key component of the equipment, the ceramic grading impeller has good impact resistance, wear resistance, easy cleaning and corrosion resistance and other properties.

[0003] For the existing ceramic grading wheel static pressure forming press, for example, a ceramic isostatic pressing machine disclosed in the utility model patent with the application number 201620083670.9, its main structure includes a high-pressure kettle filled with hydraulic oil. The hydraulic press is connected to the high-pressure kettle through a pipeline. The hydraulic press is provided with a hydraulic oil storage tank. The high-pressure kettle is provided with a sealed feeding port and a sealed discharging port. The sealed feeding port is provided with two shut-off doors, and the sealed discharging port is provided with two shut-off doors. The opening directions of the shut-off doors at the feeding port and the discharging port are both one-way openings; when in use, ceramic powder is loaded into a specific mold, and then the mold is placed on the shut-off door at the feeding port. The upper shut-off door is opened and enters between the two shut-off doors. The upper shut-off door is closed, the lower shut-off door is opened, the mold enters the high-pressure kettle, the lower shut-off door is closed, the high-pressure kettle forms a sealed space, the hydraulic press starts to pressurize, the ceramic isostatic pressing is formed, after forming, the high-pressure kettle is depressurized, the upper shut-off door at the discharging port is opened, the mold falls onto the lower shut-off door at the discharging port. At this time, hydraulic oil enters the space at this discharging port, and then flows back to the hydraulic oil storage tank through the hydraulic oil return pipeline. At this time, the lower shut-off door at the discharging port is opened, and the mold is discharged, completing one pressing.

[0004] However, most of the existing static presses require manual loading and unloading, and the working efficiency is relatively low. Moreover, the existing pressurizing methods of static presses are relatively single, it is difficult to make the mold be evenly pressurized, and it is very easy to affect the product quality. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a ceramic grading wheel static pressure forming press which can not only automatically load and unload materials, improve the working efficiency, reduce the preparation time for loading ceramics, but also can double-press the mold, enhance the pressurizing effect and improve the forming quality.

[0006] A kind of static pressure forming press for ceramic grading wheel of the utility model includes a workbench; it also includes a feeding mechanism, four groups of supporting mechanisms, a pressurizing mechanism and a liquid infusion mechanism. The feeding mechanism is installed on the workbench and drives the mold to move. The four groups of supporting mechanisms are all installed on the feeding mechanism and support the mold. The pressurizing mechanism is installed on the workbench and pressurizes the mold. The liquid infusion mechanism is installed on the workbench and conveys hydraulic oil into the pressurizing mechanism; the staff places the mold filled with ceramics on the supporting mechanism, starts the feeding mechanism to drive the mold to rotate and feed materials. By setting four groups of supporting mechanisms, the feeding rate is improved and the preparation time is reduced. Then the pressurizing mechanism pressurizes the mold, and at the same time the liquid infusion mechanism conveys hydraulic oil into the pressurizing mechanism to assist in pressurizing the mold, enhancing the pressurizing effect and improving the forming quality.

[0007] Preferably, the workbench includes a table body, a partition board, a liquid storage tank, a display screen and two groups of hydraulic cylinders I. The bottom end of the table body is connected to the ground. The partition board is installed on the table body.

The bottom ends of the two groups of hydraulic cylinders I are both connected to the top end of the partition board; the staff conveys hydraulic oil into the liquid storage tank for storage. When it is necessary to pressurize the pressurizing mechanism, start the liquid infusion mechanism to convey the hydraulic oil in the liquid storage tank into the pressurizing mechanism. Control the pressurizing pressure and the loading and unloading process through the display screen. After the supporting mechanism moves below the pressurizing mechanism, the two groups of hydraulic cylinders I push the supporting mechanism upward to make the supporting mechanism enter the pressurizing mechanism.

[0008] Preferably, the feeding mechanism includes a stepping motor, a speed reducer, a rotating box, four groups of guide columns and four groups of springs I. The stepping motor is installed on the table body. The speed reducer is installed on the table body.

After the pressurizing and forming, the supporting mechanism drives the mold to be discharged from the pressurizing mechanism. At the same time, the spring I pushes the supporting mechanism to descend to prevent the supporting mechanism from getting stuck in the pressurizing mechanism.

[0009] Preferably, the support mechanism includes a connecting plate, a tray, a sealing ring, and a mold. The connecting plate is slidably installed in the groove of the rotating box. The tray is installed on the connecting plate. The sealing ring is installed on the tray. The mold is placed on the tray. Four groups of support mechanisms are respectively installed in the grooves of the rotating box. The staff pours ceramic powder into the mold and then places the mold on the tray. When the mold rotates under the pressing mechanism, two hydraulic cylinders I push the connecting plate upward, causing the connecting plate to slide upward along the guide posts, so that the tray and the mold enter the pressing mechanism. By setting the sealing ring, the hydraulic oil in the pressing mechanism is prevented from leaking out.

[0010] Preferably, the pressing mechanism includes a pressing box, a pressure gauge, four groups of hydraulic cylinders II, four groups of springs II, a pressing plate, and a drain pipe.

A valve is installed on the drain pipe. The hydraulic cylinder I transports the tray and the mold into the inner cavity of the pressing box through the feed inlet of the pressing box. Then the liquid infusion mechanism transports hydraulic oil into the inner cavity of the pressing box. Start the four groups of hydraulic cylinders II to push the pressing plate downward, so that the pressing plate compresses the space inside the inner cavity of the pressing box, and the mold is pressed into shape. The pressure inside the inner cavity of the pressing box is detected by the pressure gauge. When the ceramic inside the mold is formed, open the valve, and the hydraulic oil inside the inner cavity of the pressing box is discharged through the drain pipe and transported to the liquid storage tank.

[0011] Preferably, the liquid infusion mechanism includes a pressure pump, a liquid suction pipe, a liquid infusion pipe, and a check valve.
