  • Patent number: 9193036
    Abstract: An abrasive water-jet machining device includes an abrasive nozzle assembly (11) that jets ultrahigh-pressure water mixed with an abrasive during a cutting process for cutting a workpiece (W) into a desired shape, a catcher cup (12) that collects the ultrahigh-pressure water jetted from the abrasive nozzle assembly (11), and a distance adjusting mechanism (13) that adjusts the distance between the abrasive nozzle assembly (11) and the catcher cup (12) so as to maintain a constant distance between the catcher cup (12) and the workpiece (W). The device increases the collection rate of the abrasive fluid when cutting a workpiece whose plate thickness changes in a longitudinal direction (vertical direction) and/or a width direction (horizontal direction).

  • Patent number: 7692123
    Abstract: A manufacturing machine manufactures a heat-source rod having a rod-like extrusion-molded article made from a combustible material with axial grooves in the cylindrical surface thereof and a heat-insulating web enveloping the article, and is provided with a apparatus 10 for spouting water to the web W in the process of the web W being fed to a wrapping section 4. The spout apparatus 10 includes an air vibrator 12 with a vibrating rod 34, and a flexible nozzle 36 attached to the rod 34 to extend across the rod 34 and supplied with water from a rate regulating pump 42. While the web W is being fed, the end of the nozzle 36 spouts water to the web W, reciprocating widthways relative to the web W due to vibration of the rod 34, and the water spouted dissolves a binder used in the web W to bind heat-insulating fiber, thereby forming a wet band H, where the wet band H has a waveform continuing along the longitudinal direction of the web W and provides a adhesive region for bonding the article.

  • Patent number: 6945859
    Abstract: A method and apparatus for controlling the coherence of a high-pressure fluid jet directed toward a selected surface. In one embodiment, the coherence is controlled by manipulating a turbulence level of the fluid forming the fluid jet. The turbulence level can be manipulated upstream or downstream of a nozzle orifice through which the fluid passes. For example, in one embodiment, the fluid is a first fluid and a secondary fluid is entrained with the first fluid. The resulting fluid jet, which includes both the primary and secondary fluids, can be directed toward the selected surface so as to cut, mill, roughen, peen, or otherwise treat the selected surface. The characteristics of the secondary fluid can be selected to either increase or decrease the coherence of the fluid jet. In other embodiments, turbulence generators, such as inverted conical channels, upstream orifices, protrusions and other devices can be positioned upstream of the nozzle orifice to control the coherence of the resulting fluid jet.
