Description

Technical Field

[0001] The invention relates to an automatic winding and molding device for a flexible sealing ring, belonging to the technical field of sealing ring injection molding. Background Art

[0002] A sealing ring is a mechanical component that achieves sealing through elastic deformation and is widely used in hydraulic systems, automotive engineering, consumer electronics, medical devices, and other fields. Its core function is to prevent liquid or gas leakage while resisting the intrusion of external impurities. Flexible graphite sealing rings can operate stably in the temperature range of -200°C to 850°C and can even withstand temperatures of 400°C in oxidizing media, far exceeding traditional rubber sealing rings. Flexible graphite has excellent tolerance to media such as hot water, oil, grease, high-temperature steam, and organic solvents, but it should avoid highly oxidizing environments. The low coefficient of friction between flexible graphite layers reduces wear without the need for additional lubrication; the high coefficient of resilience can compensate for minor unevenness on the sealing surface and maintain a long-term sealing effect.

[0003] Authorization Announcement No. (CN104553025B); The present invention relates to the technical field of sealing ring forming machines, and in particular to an automatic forming machine for flexible graphite sealing rings, wherein a punch driven by a power device is provided on the upper side of a frame, a forming seat located directly below the punch is provided in the middle of the frame, the forming seat is provided with through holes running through the upper and lower sides thereof for the punch to punch in, the lower side of the frame is provided with a material transfer and ejection device, the upper end of which extends into the through hole of the forming seat and is driven by a power device, and the forming seat is provided with a feed port communicating with the through hole. Advantages are: the roll forming process is automatically operated by the machine, with a high degree of automation and high production efficiency, which effectively reduces the demand for manpower, financial resources and material resources in the manufacturing process, greatly improves the yield rate and greatly reduces the scrap rate of products.
