Problems solved by technology

[0002] There are generally two ways to remove burrs from traditional injection molded parts. The first method is manual removal. As the name suggests, it is to manually remove burrs one by one with a knife. Although it is simple and easy to do, it is difficult to ensure roundness, flatness and surface finish. , and the work efficiency is extremely low
[0003] In recent years, a kind of sealing ring deburring equipment has appeared. The principle is to first freeze the burrs on the sealing ring with liquid nitrogen to make them brittle, and then put the brittle sealing ring into a rotary centrifuge. Fine sand, the brittle rubber burr on the sealing ring is removed by rotating the equipment with fine sand medium, but this method is suitable for the sealing ring without skeleton, if the sealing ring contains a rigid skeleton, it is easy to deform during the deburring process , so that the shape and position tolerance of the sealing ring product does not meet the requirements

Abstract

The invention discloses a deburring system for a framework-containing rubber sealing ring. The deburring system comprises a sleeve rod, a tunnel type quick-drying machine, a slideway, a core bar roller and a pre-pressing elastic deburring mechanism, wherein the sleeve rod is sleeved by a plurality of sealing rings to be treated; the tunnel type quick-drying machine comprises a tunnel cavity; a feeding hole and a discharge hole are respectively formed in both ends of the tunnel cavity; a conveyer belt is arranged at the bottom of the tunnel cavity; quick-drying liquid ejection holes are positioned on the upper side and the lower side of the conveyer belt; one end of the slideway is connected with the discharge hole of the tunnel type quick-drying machine; the other end of the slideway is arranged in a manner of being inclined downwards; the inlet of the core bar roller is connected with the tail end of the slideway; the other end of the core bar roller is arranged in the manner of beinginclined downwards; the pre-pressing elastic deburring mechanism comprises a top rack; the top rack is arranged above the core bar roller and is parallel to the core bar roller; a plurality of pre-pressing elastic deburring units are arranged at intervals at the bottom of the top rack in the rolling direction of the core bar roller. By adopting the deburring system, burr can be efficiently removed on the basis that an automobile driving cover plate sealing ring is not deformed.
