Patent number: 10828708Abstract: A band saw machine includes a base having a cutting fluid reservoir, a saw blade housing movable in an up-down direction, a pair of saw blade wheels around which a band saw blade are wound, a downstream main vise having a pair of downstream main vise jaws for clamping a product correspondent portion of the workpiece, a discharge table for discharging a product to an outside of the cutting fluid reservoir, and a product feed mechanism that feed the product cut out from the workpiece to a side on an upstream end of the discharge table. A working-side running area of the band saw blade and a working-opposite-side running area of the band saw blade are positioned within the cutting fluid reservoir, and the upstream end of the discharge table is positioned on a downstream side from a wheel center line connecting centers of the pair of saw blade wheels.Type: GrantFiled: September 27, 2016Date of Patent: November 10, 2020Assignees: AMADA HOLDINGS CO., LTD., AMADA MACHINE TOOLS CO., LTD.Inventor: Masataka Kitai

Patent number: 10442019Abstract: A feed/clamp apparatus includes a feed vise mechanism provided upstream from a cutting position, and a downstream vise mechanism provided just downstream from the cutting position. The feed vise mechanism includes first/second feed vise jaws, a downstream moving cylinder for moving the first feed vise jaw, and a downstream shifting cylinder for shifting the second feed vise jaw. The downstream vise mechanism includes first/second downstream vise jaws, a downstream moving cylinder for moving the first downstream vise jaw, and a downstream shifting cylinder for shifting a second downstream vise jaw. A vise surface of the second downstream vise jaw is located on one side of the vise reference position when the downstream shifting cylinder is located its stroke end on the one side. A thrust force of the downstream shifting cylinder toward the one side is made equal to a thrust force of the downstream moving cylinder toward another side.Type: GrantFiled: September 23, 2016Date of Patent: October 15, 2019Assignees: AMADA HOLDINGS CO., LTD., AMADA MACHINE TOOLS CO., LTD.Inventor: Masataka Kitai

Patent number: 9821388Abstract: A horizontal band saw machine includes a base, a vertically-movable housing disposed above the base, a pair of wheels that are disposed at a lower portion of the housing and a distance between whose axis lines is changeable, a band saw blade lopped over the pair of wheels, and saw blade guides that are provided on the base. An installation position of the band saw blade is set lower than a cutting end position of a workpiece to be cut by the band saw blade. The housing can move the pair of wheels to the installation position. The pair of wheels can be inserted into an region surrounded by the band saw blade that is set on the saw blade guides when being moved to the installation position with the distance shortened.Type: GrantFiled: February 7, 2014Date of Patent: November 21, 2017Assignees: AMADA HOLDINGS CO., LTD., AMADA MACHINE TOOLS CO., LTD.Inventors: Akio Seto, Masataka Kitai

Publication number: 20140360324Abstract: A feed vise is configured to position a work material on a pass line. A band saw blade has zero twisting, and is configured to cut the work material into a length smaller than a diameter of a driving wheel. A product discharge vise has product discharge vise jaws. The product discharge vise jaws clamp the work material, and the band saw blade is configured to be lowered and cut the work material. After the cutting is completed, the product discharge vise is configured to discharge a product, which is obtained by cutting the work material, below the pass line, while the product discharge vise clamps the product.Type: ApplicationFiled: November 19, 2012Publication date: December 11, 2014Applicants: AMADA MACHINE TOOLS COMPANY, LTD., AMADA COMPANY, LIMITEDInventors: Toru Tokiwa, Masataka Kitai
