Processing method applied to flexible graphite metal wound gasket

Abstract

The invention relates to a machining method applied to a flexible graphite metal winding gasket and belongs to the technical field of sealing gasket manufacturing. At first, blank pieces of an outer ring and an inner ring of a steel plate are subjected to one-time punch forming through a punching machine, and then an inner circle and an outer circle of the outer ring and an inner circle and an outer circle of the inner ring are subjected to finish turning machining. After finish turning machining of the outer ring and the inner ring is completed, for the outer ring and the inner ring, a platform lifting adjusting frame is adopted for adjusting the interval between a conveying platform and an abrasive belt mill rack, and the abrasive belt water milling process of the two end faces of the outer ring and the two end faces of the inner ring is completed. Meanwhile, under the common effect of a pressing wheel on a winding rack and a guide winding wheel, a winding elastic assembly carries out attached type staggering winding machining on a graphite belt and a metal steel belt. Finally, after a locating pressing disc of the winding elastic assembly is adopted for carrying out oil pressurepressing and die closing with a locating chassis, the assembling process is completed. The method has the advantages that locating is accurate, installing is convenient, the production efficiency ishigh, the sealing performance is good, and the quality stability is good. The assembling defect is avoided, the product quality is improved, and meanwhile the machining period is shortened.

Description

technical field [0001] The invention relates to the technical field of manufacturing sealing gaskets, in particular to a processing method applied to flexible graphite metal winding gaskets. Background technique [0002] Metal wound gasket is a kind of sealing gasket widely used at present. It is the sealing element of flange joints such as steam pipelines and oil pipelines. Strengthen four types. In the chemical and pharmaceutical industries, the liquid medicine in the production process is transported through pipe splicing, and the sealing function is guaranteed by winding gaskets between the spliced ​​pipes. The wound gasket is composed of a supporting ring on the inner ring, a positioning ring on the outer ring and an intermediate filling and sealing structure wound and filled between the two. The support ring and the positioning ring are usually made of metal materials, and the intermediate filling and sealing structure can use graphite or polytetrafluoroethylene acco...
