摘要:
A groove engraving device and a groove engraving method are provided. The groove engraving device includes: a processing chamber for containing a piece to be processed, a cutter for groove engraving on the piece to be processed, a clamping mechanism for clamping the piece to be processed, a driving mechanism for driving the clamping mechanism to rotate, and a temperature controlling device for controlling a temperature inside the processing chamber to be within a preset temperature range. The clamping mechanism and the cutter are disposed inside the processing chamber, and the clamping mechanism is rotatable with respect to the processing chamber. The temperature controlling device is disposed inside the processing chamber. The groove engraving device can improve the processing efficiency and quality of the groove engraving on the piece to be processed.

A ring holder system comprising a ring holder base with a body that can be oriented horizontally and vertically on a flat work surface. The base includes a single mandrel extending from a front end face of the base, angled upper tool mounting surfaces circumferentially offset from a top surface of the base, and a flat rear end face for resting the base in a vertical work orientation on a flat surface. A horizontal tool adapter mount is configured to be removably mounted on one of the angled upper tool mounting surfaces, and a vertical tool adapter is configured to be mounted on the bottom surface of the base in the vertical work orientation. The mandrel includes a threaded mounting ring at an inner end of the mandrel adjacent the front end face of the base for mounting accessories such as vises and pitch cups rotatably on the mandrel in the vertical work orientation.

A universal cylinder mount for mounting a at least one of a plurality of cylinders between a headstock and a tailstock of an engraver. Each of the cylinders have a mounting aperture at each end adapted to receive a universal cylinder mount associated with each of the headstock and tailstock. The universal cylinder mount is adapted to accommodate a plurality of mounting apertures formed with different sizes and having various sloped walls for facilitating alignment and frictional gripping engagement of the cylinders.

A method and apparatus for automated loading and unloading of a cylinder in an engraver. The method and apparatus permit the engraver to accommodate cylinders of differing geometries, including a range of lengths, diameters and mounting configurations. The engraver includes a headstock and a tailstock which cooperate to rotatably support a cylinder at an engraving station in the engraver. The engraver includes a cylinder handling system having at least one cylinder supporting the cylinder between the headstock and the tailstock during the loading and unloading of the cylinder. The cylinder handling system includes a driver for driving the cylinder support towards and away from the engraving station until the headstock and the tailstock engage and rotatably support the cylinder. Once the cylinder is rotatably supported between the headstock and the tailstock, then the cylinder support is retracted. The cylinder support includes a telescoping support member having a support nest for engaging and supporting the cylinder at the engraving station.

A rolling mill is rotated while microscopic dents with peripheral ridges are formed by an intermittent laser beam in the presence of a gas jet directed at the beam impact zone. The output and the angle of incidence of the gas jet are controlled and microscopic dents are formed with a ridge on only part of their periphery. Steel sheet cold-rolled by means of such a roll has uniformly distributed hollows, each hollow partially surrounding an elevation.

A piercing machine for marking writings, numbers and the like on metallic curved surfaces, such as the ogive-shaped portion of steel cylinders, which allows for the marking by engraving also of symbols varying from one piece to be marked to another, without hand substitution of the piercer elements. The piercers are disposed and held on a disc along a spiral arrangement. This disc may be operated and driven into rotation by two independent mechanisms, one for the engraving of the symbols which are always the same, and the other for the variable symbols. The first mechanism causes and intermittent mono-directional rotation movement, while the second mechanism causes a continuous rotation, in both the senses. The disc bearing the piercers can be brought into rotation alternatively by only one of said two mechanism, but in any case, during its rotation, it is also subjected to a rectilinear translation which, combined with the rotation, is such that the piercers disposed along a spiralshaped line, are always aligned with a hammering means the operating axis of which is stationary.

A character dial assembly used with a machine for engraving characters on finger rings and other metallic ornamental articles, which comprises a lower circular dial member and an upper circular dial member having a diameter smaller than the lower dial member. Each of the two dial members has its upper surface engraved with a set of various characters which are disposed circumferentially on the dial member in equal spaced relationship with one another. The lower dial member also has its upper surface impressed with index characters on its upper surface corresponding to the characters engraved thereon and disposed radially outwardly of the corresponding engraved characters. The upper dial member has a cut out section for obtaining access to the engraved characters on the lower dial member. The lower and upper dial members are coaxially connected together for rotation relative to each other.
