Publication number: 20170304969Abstract: There are provided a bolt caulking method and a bolt caulking device which ensure supply and caulking of a bolt as a single operation. The method is a bolt caulking method including supplying a bolt into a nose piece having a vertical hole, and lowering a punch from above to drive the bolt into a metal plate. The bolt is supplied through a pipe connected to a side of the nose piece, and dropped into a vertical hole formed in the nose piece along an inclined hole formed at a tip end of the pipe with a head part of the bolt being located on the topside. Thereafter, the punch which ejects air from a central hole is lowered within the vertical hole to drive the bolt into a metal plate while holding the bolt at a lower part of the vertical hole by the ejecting air flow.Type: ApplicationFiled: March 6, 2017Publication date: October 26, 2017Applicant: AOYAMA SEISAKUSHO CO., LTD.Inventors: Naoki HOSHINO, Toshiya MORI, Yukinori FUJIMOTO

Patent number: 9764371Abstract: The invention is directed to a method for caulking a caulking member such as a caulking nut or a caulking bolt to a metal plate. The metal plate is arranged on a die having a caulking protrusion formed on an end surface thereof, the caulking member is arranged on the metal plate while a position of a caulking recess portion of the caulking member is aligned with the caulking protrusion, and a punch is brought closer to the die so that the caulking member is pressed against the metal plate. While an upper surface of the metal plate in a position opposite to the caulking recess portion is restricted by a downward protruding portion of the punch or by the caulking member, the metal plate is plastically fluidized into the caulking recess portion, so that the caulking member is caulked without boring a hole in the metal plate.Type: GrantFiled: November 6, 2013Date of Patent: September 19, 2017Assignee: Aoyama Seisakusho Co., Ltd.Inventors: Yukinori Fujimoto, Tsuyoshi Kojima

Publication number: 20170219001Abstract: A bolt for peeling a coating film of the present invention includes notch parts 6 for peeling a coating film, the notch parts being formed over a plurality of pitches at top parts of screw threads in a male screw part 3 formed in a shaft part 2. The bolt is characterized in that the respective notch parts 6 formed over the plurality of pitches are arranged to be greatly inclined at an angle of 40° to 50° to an axial line 12 of the shaft part 2. Since the respective notch parts can be rolled sequentially, it is possible to form the notch parts 6 to be deeper and sharper than conventional ones and to enhance the coating film peeling performance. Also, the coating film peeled can be discharged efficiently as compared with conventional cases.Type: ApplicationFiled: April 21, 2017Publication date: August 3, 2017Applicant: AOYAMA SEISAKUSHO CO., LTD.Inventors: Yuichi HIROI, Masashi OKAMOTO, Tomoyuki FUKUCHI, Yukinori FUJIMOTO
