First through fourth guide parts are formed on the fixed block, slider and bit support block, to constitute dovetail joints. The first guide parts of the fixed blocks and second guide parts of sliders are formed to have a slope, such that, as the sliders are lowered, they are horizontally moved toward each other. A lower portion of a broaching bit is formed as a supporting surface, and at least one broaching edge portion is formed above the supporting surface portion.Type: GrantFiled: February 17, 2003Date of Patent: May 2, 2006Inventor: Hong-Soon Park

Patent number: 7007371Abstract: A method of manufacturing a speed ring in a continuous process using a magnetizing fixture and a trimming fixture. An unmagnetized magnetic strip is fed into the trolley of a magnetizing fixture, clamped stretched, and magnetized by a coil. The newly magnetized strip is then cut and fed into a trimming fixture. As the magnetized strip goes through the trimming fixture, it runs over a hall effect sensor which determines where a center of a pair of poles is located. Based on where a pair of poles is located the cutting blade of the trimming fixture is activated and a magnetic strip that can be turned into a speed ring is created.Type: GrantFiled: September 24, 2003Date of Patent: March 7, 2006Assignee: Sauer-Danfoss Inc.Inventors: Stanley N. Didier, Scott Kessler

Patent number: 6993950Abstract: A portable devic for bending and cutting rebar, reinforcing rod, and the like. For cutting, a shaft assembly is movable along a first longitudinal axis (A—A) between a retracted and an extended position. A movable cutting head carried by the shaft assembly coacts with a fixed cutting head to shear rebar disposed between the cutting heads when the shaft assembly is moved to the extended position. For bending, a push rod movable along a second longitudinal axis (C—C) parallel to the first axis (A—A) couples movements of the shaft assembly through a clevis to a crankshaft such that longitudinal movements of the shaft assembly cause rotational movements of the crankshaft about an axis substantially perpendicular to axis (A—A). A first driven wheel, mounted for rotation with the crankshaft, has one or more bending blocks attached to the wheel by a radial arm.Type: GrantFiled: August 25, 2003Date of Patent: February 7, 2006Inventor: William Bryan

Patent number: 6978532Abstract: A method of forming a durable mower bed blade is provided in which the grain of the metal is perpendicular to the longitudinal axis of the blade. The blade is formed in part by coining the blade on a hydraulic press which strengthens the cutting edge and other areas to prevent chipping and cracking. Additional steps in the process include shearing the blade to a proper width, heat treating and grinding the edge of the blade to sharpen it.Type: GrantFiled: November 7, 2003Date of Patent: December 27, 2005Assignee: JRM, Inc.Inventor: James R. Merritt

Patent number: 6968721Abstract: A method of manufacturing a turbine blade retainer using a material cutting device and a material bending device includes steps for suspending a bar stock material between a polyurethane shock absorber and a bore of a cutting jig support, moving the cutting punch downward to press the distal end of the bar stock material into the shock absorber and then cut the bar stock material to thereby generate a blank, clamping the blank between a bending punch and a receiving slide by pressing the bending punch against the receiving slide, bending the distal end of the blank against a chamfered section of a bending support in response to continued downward motion of the bending punch to thereby form a blade retainer precursor, and milling the blade retainer precursor to form the blade retainer. Corresponding devices for performing these steps are also described.Type: GrantFiled: March 28, 2003Date of Patent: November 29, 2005Assignee: Minebea Co., Ltd.Inventors: Kenjiro Tabuchi, Go Nabatame

Patent number: 6813922Abstract: A digitally controlled machine for bending, forming, or curving raw parts, such as rods, wires or profiled sections, comprises a conventional main frame (1) and a rotating bending head capable of bending articles in different planes. The rod (4) is horizontally displaced along a transport axis (5) by a feed station, located upstream, and is brought through a bending shank (7) borne by the main frame (1). The rod is then brought through a lathe (10) of the bending head. The lathe is formed by a bending roll (8) and a folding pin (9), and is capable of rotating in a horizontal plane about an axis of rotation aligned with the axis of the bending roll (8). The bending shank (7) is movably mounted in translation in a transport axis (5) and is continuously displaced between one or more projecting bending positions wherein the shank is proximate to the roll (8) and one or more retracted positions, facing upstream, which completely clear the bending zone between the lathe and the main frame.Type: GrantFiled: October 1, 2002Date of Patent: November 9, 2004Assignee: NumallianceInventor: Joël Etienne

The anvil member has a track extending longitudinally of the anvil member and the brake. The track includes a pair of parallel channels that are at an angle to each other, and are laterally spaced from each other—i.e., laterally of the longitudinal dimension of the brake and the longitudinal direction of the track. The track also includes a second channel extending along the anvil member parallel to the first channel and disposed between the lip and the clamp surface. A cutter has a frame, and first and second pairs of track rollers mounted on the frame.
