摘要:
Disclosed is an automatic metal printer which prints a camera-photographed and computer-processed image on a surface of a hard material, such as a metal sheet, through a dot matrix printing type method wherein brightness of the printed image is expressed in accordance with density of dots in the dot matrix formed on the surface of the hard material. The automatic metal printer includes a platform which reciprocates forward and rearward in a lower portion of a body by a motor-operated first ball screw. A saddle is installed at a position above the platform so as to reciprocate to the left and right in the body by a motor-operated second ball screw. A dotter is vertically installed on the saddle so as to dot the upper surface of the hard material seated on the platform to print a desired image.

This disclosure relates to a machine for applying characters to a structural component, such as an automotive chassis, engine block, or the like, and includes first and second means for moving marking means along first and second paths substantially normal to each other, means for vibrating the marking means along a third path substantially normal to the first and second paths, and control means for selectively energizing and deenergizing the first and second moving means as well as the vibrating means for selectively marking a structural component during movement of the marking means along the first and second paths.

A marking device for encoding metallic workpieces with two-dimensional matrix codes includes a striking tool for forming the code recesses, driven by an electromagnetic device. The driving movement is performed against the force of a return device. A positioning device displaceable on two axes (x, y) of a plane perpendicular to the striking direction (z) is used for positioning the striking tool in the desired code positions. An electronic control device for controlling movement of the striking tool includes means for presetting a higher current for the electromagnet device during a first acceleration phase of the striking tool and a lower current during a subsequent moving phase until the workpiece is impinged. In this manner, the precision of the code recesses in the workpiece can be exactly set or maintained, so that readability of the coding is substantially improved.

A machine for cutting a ''checkering'' pattern or other ornamental pattern in a gun stock or other structure by means of one or more cutter structures having cutting edges shaped in correspondence with the desired pattern, with the machine acting to produce relative vibratory movement of the cutter structure and work piece, and preferably also relative oscillatory movement in a second direction, and in a controlled manner very positively and effectively forming the pattern in the work piece.

A laser beam 7 from an engravement portion softening mechanism 6 of an apparatus is condensed onto an engravement portion on an engravement surface of a workpiece 1 for softening the engravement portion. When the hardness of the engravement portion is lowered, a pen tip 2 of the apparatus is applied to the engravement portion. Thus, it is possible to reduce reliably wear and damage of the pen tip 2 which results from engraving a hard workpiece, and to prolong the useful life of the pen tip 2, so that the durability and the reliability of the apparatus are improved.

摘要:
A method for embossing indicia such as numbers, letters, or other symbols into an article of malleable material such as a thin sheet or web by providing an anvil which has the appropriate indicia defined by a plurality of individual protuberant dots, positioning the article against the anvil in contact with the protuberant dots, and applying an ultrasonically vibrating horn to the article and forcing it against the dots to form indentations. Relative translational movement can be effected between the horn and the article when the indicia cover a greater area than the surface of the horn. The horn can be non-rotating, or can rotate along the surface of the article. The method is particularly applicable to the marking of photographic film and paper.

A machine for cutting a ''checkering'' pattern or other ornamental pattern in a gun stock or other structure by means of one or more cutter structures having cutting edges shaped in correspondence with the described pattern, with the machine acting to vibrate the cutter structure and preferably also oscillate the structure orbitally during such vibration in a controlled manner very positively and effectively forming the pattern in the work piece.
摘要:
A workpiece which is to have a raised pattern applied to at least one surface thereof is positioned in the apparatus between a support member and a die member, the surface of the die member being a reverse image of the desired pattern. While the die member and workpiece are held in contact by a static force, highfrequency vibrations are applied to impress the pattern on at least one surface of the workpiece. Several alternate embodiments involve rotating dies or relative movement between the source of vibrations and the die and workpiece in a plane perpendicular to the direction of the high-frequency vibrations.
