[0003] At present, the existing domestic market mainly uses traditional bearings to add high and low temperature grease lubricants. Regardless of whether imported or domestic bearings are used, there are problems such as high prices and short service life. In addition, repeatedly adding lubricants inside the bearings will cause environmental pollution and affect environmental protection. Graphene solid lubrication bearings use high-purity graphite materials as solid lubricants, which are non-toxic and harmless to the environment and can provide long-term continuous lubrication. It provides equipment in various industries with bearing components that are free of cleaning, maintenance, and pollution to the environment, thereby greatly improving the service life of the equipment.

[0004] In the traditional manufacturing process of graphene solid lubrication bearings, the material high-pressure molding process usually relies on manual operation, which has the problems of unstable finished product quality and low production efficiency. Especially in the process of graphite material laying and high-pressure molding, due to uneven pressure or insufficient filling of graphite material, it is easy to cause inconsistent surface hardness and internal voids in the bearing. Therefore, problems gradually arise in the subsequent production process of the bearing, mainly manifested as surface defects and surface cracks that cause the internal rolling elements of the bearing to be exposed and unable to undergo subsequent processing, resulting in material waste and low production efficiency. Therefore, it is urgent to study graphene solid lubrication bearing high-pressure molding equipment that can ensure the efficiency and consistency of graphene solid lubrication bearing manufacturing.
