Description

TECHNICAL FIELD

[0001] The utility model relates to ceramic ball processing auxiliary equipment field especially, relates to a shovel ball board for silicon nitride ceramic ball processing. BACKGROUND

[0002] Silicon nitride ceramic ball is precision ceramic sintered at high temperature in non-oxidizing atmosphere, which has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, and can be used in seawater for a long time, and has good performance of electric and magnetic insulation.

[0003] Silicon nitride ceramic ball needs to be shaped before high-temperature sintering, and the existing shaping work adopts hand winding and machine pressing. The ceramic balls pressed by the machine are generally pressed in batches. After the ceramic balls in the previous batch are pressed, the jacking mechanism on the workbench will lift the ceramic balls in the mold, and then the shovel ball plate at the bottom of the moving hopper will push the pressed ceramic ball prototype to the storage area. Then, when the hopper passes through the mold, the powder in the hopper will fall into the mold for filling to prepare for the next pressing.

[0004] After searching, the patent announcement number CN218424579U discloses a shovel ball plate for silicon nitride ceramic ball processing, which is applied in the field of ceramic ball processing auxiliary equipment, and includes a bottom plate and a storage mechanism. A material passing groove is formed in the top of the bottom plate, and an air cavity is formed in one side of the bottom plate. An air pump is arranged on the top of the bottom plate. The utility model can extract the powder on the workbench surface through the air pump, recycle the powder into the collection box, and automatically collect the powder without manual cleaning, which improves the cleaning speed and efficiency and reduces the labor intensity of the workers. A reset spring is installed on the connecting plate in the connecting seat. When the connecting plate drives the push plate to move and push the ceramic ball prototype, the connecting plate retracts into the connecting seat, which can release part of the hard contact force and prevent the push plate from causing hard push marks on the ceramic ball prototype, thereby ensuring the integrity of the processed ceramic ball.

[0005] Although the above technical solution realizes the extraction of the powder and the buffering of the ceramic ball prototype, it cannot be adjusted in size and angle. When the push plate is used to push the small ceramic ball blank, the ceramic ball blank may fall off from the gap at the bottom of the push plate. Conversely, when the push plate is used to push the large ceramic ball blank, the push plate may reach the lower part of the ceramic ball blank, which not only increases the contact points between the push plate and the ceramic ball blank, causing the deformation of the ceramic ball, but also causes the ceramic ball blank to flip over the push plate, thereby affecting the quality of the ceramic ball and the normal production.
