Abstract
The present invention relates to the field of forming technologies for rubber sealing ring blanks, and more particularly to an automatic forming method and device for a rubber sealing ring blank. A cutting blade is fixedly connected to the surface of a blank forming assembly; an equipment body II is fixedly connected to a sliding table die set; a supporting rod II is fixedly connected to the surface of the equipment body II; a blank box is fixedly connected to the inner side surface of the supporting rod II; and a blank spool is fixedly connected to the tail end of a long blank strip. The method and device disclosed by the present invention have the advantages that the automation degree is high, and the long blank strip conveyed from the blank spool passes through guide wheels and a guide groove and is automatically pressed into a ring through the combined action of the blank forming assembly and the cutting blade. According to this patent technology, feeding is performed by means of continuous introduction of the blank strip; and automatic formation of the blank ring is achieved through the action of an automation assembly. Except for a process of replacing the blank spool after t…
