Description
Technical Field
[0001] The utility model relates to the technical field of O-ring production, in particular to a grinding and cleaning device for O-ring production. Background Art
[0002] An O-ring is a rubber sealing ring with a circular cross-section. Because of its O-shaped cross-section, it's called an O-ring. O-rings are typically vulcanized using a combination of upper and lower molds, requiring trimming after forming. Common methods for deburring O-rings include manual trimming with surgical blades and water-based trimming. Water-based trimming uses water and a specific abrasive as a medium, then vortex-polishes the O-ring and the medium together to remove burrs.
[0003] When water-grinding an O-ring, the O-ring and abrasive are placed together in a rotating cylinder, and the O-ring is polished by the rotation of the cylinder. However, the contact effect between the O-ring and the abrasive inside the unidirectional rotating cylinder is limited, and they may even move synchronously, affecting the polishing efficiency of the O-ring. In addition, the O-ring is difficult to separate from the abrasive after polishing, which often takes a lot of time and effort for the workers. Utility Model Content
