Description

Technical Field

[0001] The invention relates to the technical field of graphite valve gasket production, in particular to automatic loading and unloading polishing equipment and a polishing method for graphite valve gaskets. Background Art

[0002] Graphite valve gaskets are cut or stamped from pure graphite plates or metal (toothed plates, flat plates, mesh) reinforced graphite plates. They have many excellent sealing properties, such as thermal stability, self-lubrication, corrosion resistance, no aging, no brittleness, etc. They can be used stably for a long time under harsh working conditions and rarely require maintenance. The lining material can be selected from different metal sheets. In the production process of graphite valve gaskets, the graphite valve gaskets need to be polished to ensure the accuracy of the graphite valve gaskets. For the loading and unloading of graphite valve gaskets, usually a mechanical arm or manual loading is used separately, and then polishing is performed. After the graphite valve gaskets are polished, they are removed one by one. In this process, the time interval for replacing the graphite valve gasket is long, which reduces the efficiency of its production. For this reason, we propose a graphite valve gasket automatic loading and unloading polishing equipment and polishing method. Summary of the invention
