20190315434 · 2019-10-17 ·

A method of making a bicycle sprocket having a rotational center axis basically includes providing an annular portion and forming a first tooth and a second tooth. The annular portion is made of a base material and has a plurality of teeth. At least one of the teeth is processed to form a first tooth, and at least one other of the teeth is processed to form a second tooth. The first tooth has a first axial chain engaging width that is smaller than a first axial spacing of an outer link of a bicycle chain and larger than a second axial spacing of an inner link that is coupled to an outer link. The second tooth is formed to have a second axial chain engaging width that is smaller than the second axial spacing. The second tooth is formed by deforming the base material.

METHOD AND APPARATUS FOR PROGRESSIVELY FORGING A MOBILE DEVICE CASING
20190299268 · 2019-10-03 ·

A method and apparatus for progressively forging a mobile device casing is described. The method may include advancing an initial mobile device casing cut from an extruded sheet through a plurality of stations of a transfer die assembly. The method may also include performing a sequence of forgings on the initial mobile device casing to progressively form a mobile device casing having at least one three dimensional feature formed within at least one cavity of the progressively formed mobile device casing.

METAL SHEET MOLDING METHOD

A machining surface of a die are provided with a pair of inclined surfaces facing each other across a gap and a flat surface interposed therebetween. Each inclined surface includes an inner end portion on a side near the flat surface and an outer end portion on a side farther away from the flat surface. The molding method includes a mounting step of mounting the metal sheet on the die to span both inclined surfaces, and a pressing step of forming a reduced-thickness portion by pressing the metal sheet between the punch and the inclined surfaces of the die. The pressing step includes setting a bottom dead center of the punch to maintain a gap formed between the inner end portion and a surface of the metal sheet facing the inner end portion.

FORGED FRAME HANDCUFFS
20190284844 · 2019-09-19 ·

A method of manufacturing a handcuff includes bending a first bar of alloy into a curve roughly matching a shape of a desired cheek plate half, heating the first bar to a forging temperature, die forging the first bar into a first cheek frame forging having a first lockset cavity portion, and trimming the first forging to a form a first forged cheek from half having a first cheek arm. This is repeated with a second bar to obtain a second forged cheek frame half having a second cheek arm. The first cheek frame half is joined directly to the second cheek frame half, the first lockset cavity portion and the second lockset cavity portion combining to form a lockset cavity. A bow is pivotally attached between the first and second cheek arms and a lockset is installed in the lockset cavity.
