Description

Quartz crucible automatic forming device

technical field

The utility model relates to production equipment for a quartz crucible, in particular to an automatic molding device for a quartz crucible.

Background technique

The quartz crucible is prepared by the vacuum arc method. The high-purity quartz powder is put into the quartz crucible mold that can be tilted and rotated in the circumferential direction. Move the rotating quartz crucible mold to the electrode rod, feed the electrode to start the arc and insert it into the formed quartz powder, and start the vacuum system at the same time to make it melt quickly to form a quartz crucible-shaped fused silica, take it out after cooling, that is Complete the production of a crucible.

At present, the molding of quartz crucible is completely dependent on manual operation, and the wall thickness of quartz crucible is completely dependent on artificial vision. Errors caused by human control lead to uneven wall thickness and inconsistent quality of quartz crucible.

Contents of the invention

The utility model aims to solve the above-mentioned technical problems, and provides an automatic quartz crucible molding device, which can avoid errors caused by human control, improve the molding accuracy of the quartz crucible, and make the quartz crucible have uniform wall thickness and consistent quality everywhere.

The technical solution of the utility model is:

Quartz crucible automatic molding device, including a fixed frame, its special feature is: the swing frame is installed horizontally on the fixed frame, and the swing power source connected with the swing frame is installed on the fixed frame; the lifting frame is installed by sliding up and down on the swing frame, swing The lifting power source connected with the lifting frame is installed on the frame; the telescopic frame is installed horizontally on the lifting frame, and the telescopic power source connected with the telescopic frame is installed on the lifting frame.

Further preferably, the swing power source is a servo motor.

Further preferably, the lifting power source is an electric push rod.

Further preferably, the telescopic power source includes a lead screw installed on the lifting frame, a screw nut mounted on the telescopic frame and screwed to the lead screw, and a rotating handle installed at the tail end of the lead screw.

Further preferably, the swing frame and the fixed frame are installed through bearings.

The beneficial effects of the utility model are:

Due to the horizontal rotation of the swing frame installed on the fixed frame, the vertical sliding of the lifting frame mounted on the swing frame, and the horizontal sliding of the telescopic frame mounted on the lifting frame, under the joint action of the above structures, the forming scraper mounted on the front end of the telescopic frame can be precisely controlled. The plate moves left and right, up and down, and forward and backward, avoiding errors caused by human control, improving the molding accuracy of the quartz crucible, making the wall thickness of the quartz crucible uniform and the quality consistent everywhere.

Description of drawings

Fig. 1 is a structural representation of the utility model;

In the figure: 1-fixed frame, 2-oscillating frame, 3-servo motor, 4-lifting frame, 5-electric push rod, 6-telescopic frame, 7-screw, 8-screw nut, 9-rotating handle, 10 - forming scraper, 11 - mould.

Detailed ways

As shown in Figure 1, the quartz crucible automatic forming device comprises a fixed mount 1, on the fixed mount 1, a swing frame 2 is installed by bearing horizontal rotation, and a servo motor 3 connected with the swing frame 2 is installed on the fixed mount 1; The lifting frame 4 is installed by sliding up and down through the slideway, and the electric push rod 5 connected with the lifting frame 4 is installed on the swing frame 2; Connected telescopic power source, the telescopic power source includes the lead screw 7 that is rotated and installed on the lift frame 4, the screw nut 8 that is installed on the telescopic frame 6 and is threadedly connected with the lead screw 7, and is installed on the lead screw 7. The turning handle 9 of 7 tail ends. The front end of the telescopic frame 6 is equipped with a molding scraper 10 consistent with the curvature of the inner wall of the quartz crucible.

First install the fixed frame 1 on one side of the mold 11, start the servo motor 3, rotate the lifting frame 4, and make the forming scraper 10 rotate above the mold 11; then start the electric push rod 5, lower the lifting frame 4, and make the forming scraper 10 The bottom end is close to the inner bottom surface of the mold 11; then the handle 9 is rotated, and the telescopic frame 6 is moved backward so that the rear end of the forming scraper 10 is close to the inner wall of the mold 11, and finally the quartz powder is poured into the mold 11 through the quartz powder feeding mechanism, and the surrounding The mold 11 is rotated, and the quartz powder is evenly scraped on the inner wall of the mold 11 by the forming scraper 10 . Reduce the error caused by human control and ensure the consistency of crucible quality.

The above are only specific embodiments of the utility model, and are not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
