Patent number: 10166582Abstract: A spinning method includes supporting a supported portion of a cylindrical work by a work supporting portion. The method includes pressing a roller of a spinning head against an outer peripheral surface of a processed portion of the work while revolving the roller. The method also includes performing a forming process that points a tube axis of the processed portion of the work in a given direction by moving the processed portion relative to the work supporting portion or moving the work supporting portion relative to the processed portion, while making a core bar inserted into the processed portion of the work contact an inner peripheral surface of the processed portion.Type: GrantFiled: April 1, 2014Date of Patent: January 1, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yukitaka Kunimoto, Satoshi Shionoya, Takashi Yamamoto

Patent number: 8020422Abstract: A tubular product comprises a side section having outer surfaces disposed along a parallelogram and a bottom section formed on one end of the side section. The outer surfaces of the side section are pressure formed by a roller. The tubular product preferably is manufactured from a tubular material by a process comprising the use of a device having a roller that is configured to engage with a side section of the tubular material. The device also comprises a mandrel configured to position the tubular material so that the roller can apply pressure against at least a portion of the outer surfaces of the side section and can extend the side section of the tubular material to form the product.Type: GrantFiled: March 7, 2008Date of Patent: September 20, 2011Assignee: Kabushiki Kaisha KunitecInventors: Yukitaka Kunimoto, Toshiya Saito
