摘要:
A blasting or stripping booth is provided creating a generally downward flow for treatment of fluid and particle flow, which reduces operator exposure to potentially hazardous debris. The booth comprises an enclosure defining an upper region for a workpiece, a lower region, and a separator assembly. In some instances the separator assembly includes individual separator units which are discrete units, each having a generally square or rectangular plan view configuration which are arranged in an array for providing the required process flow capabilities. Further embodiments utilize structures forming the separator which have an elongated trough-like configuration. These embodiments find a particular application in large-scale stripping or blasting booth used in production environments where workpieces may flow through a treatment system in a serial manner. Other suitable applications include batch type processing of parts.

Disclosed herein is a system for surface treating an internal surface of a part. The system comprises a tank within which the part is locatable. The system also comprises a fluid within the tank and capable of submersing the part when the part is located within the tank. The system further comprises a nozzle submersed in the fluid and configured to generate a stream of cavitated fluid directed in a first direction. The system additionally comprises a deflection tool submersed in the fluid and comprising a deflection surface that redirects the stream of cavitated fluid from the first direction to a second direction. The first direction is away from the internal surface of the part and the second direction is toward the internal surface of the part.

According to one implementation, a blast treatment device includes at least one nozzle that injects media toward a workpiece, a first tank that supplies the media to the at least one nozzle, a movement structure that moves the at least one nozzle and the first tank, and a second tank that supplies the media to the first tank. The second tank is not moved by the movement structure.

An apparatus for blasting a media onto a surface comprises an oscillating nozzle, a mount and a power source. The mount attaches the nozzle to tooling, enabling the nozzle to be raised and lowered about a vertical axis, and enabling the nozzle to be repositioned about a horizontal axis. The power source enables the nozzle to oscillate. The blasting media is sprayed through the nozzle onto the surface. The oscillating nozzle projects an enlarged dispersion pattern of the blasting media onto the surface being treated. The apparatus may include a basket positioned near the mount, enabling an operator to be positioned upon a truss and control the blasting of the media onto the surface, the basket being mounted via a swivel bearing, enabling the basket to self-level. Also, the media blasting apparatus may be controlled by an operator positioned in a remote control computer area.

The system delivers media blasting material to an interior surface of a large storage tank comprises a substantially upright support structure secured to the surface to be blasted. The upright support structure is preferably vertical. A frame extends across the upright support structure. An extendable arm is affixed to the frame at a section. The section is securely and pivotably attached to the section in such a way to enable the arm to rotate freely inside the large storage tank, so that the blaster secured at the end of the extendable arm can blast the entire interior surface of the large storage tank while the upright support structure remains in place. A robot blaster is positioned at the end of the extendable arm and performs the media blasting. A work station is located nearby the site of the large storage tank and controls the position of the extendable arm relative to the interior surface being blasted via a processor and the operation of the blasting delivery system. The surfaces to be blasted may also include the exterior surface of all types of large storage tanks and structures, ship hulls, exterior and interior building wall surfaces.

The present invention relates to a method and a system for machine cutting several parts (31, 32, 33, 34) out of a piece of material using a beam cutting technology. The invention provides a set of controlling rules and variables for cutting two dimensional shapes or patterns. One rule or a combination of several rules are used for the cutting operation depending on the shape or pattern to be cut, the shape or pattern forming the parts (31, 32, 33, 34) out of the piece of material. The present invention specifically teaches that the set of controlling rules comprises rules for the forming of a cluster (3A) of parts with free form shapes, the parts being positioned so close to each other so that only the thickness of one cut from the cutting beam is found between adjacent parts whenever the shape of the parts allows it.

A stringer manufacturing method for machining one end portion of an elongated member that is provided with a cap flange, a web, and a base flange and that has an inverted T-shape in a front view, an I-shape in a front view, or a T-shape in a front view into a desired shape to obtain a desired stringer. The one end portion of the elongated member is machined into a desired shape by using a vertical articulated robot (1) that has at least 6 axes and that has, at the tip of a valve unit (13), an abrasive nozzle assembly (14) that injects ultrahigh-pressure water containing abrasive and a catcher cup (15) that recovers the ultrahigh-pressure water ejected from the abrasive nozzle assembly (14).

Particle-delivery devices, abrasive jet systems, and associated devices, systems, and methods are disclosed herein. In certain aspects, the particle-delivery devices can include an elongated fluidizing chamber and a metering assembly. The metering assembly can include a particle flow path extending from the fluidizing chamber. The metering assembly can also include a carrier-gas passage extending to an injection orifice proximate the fluidizing chamber. The metering assembly can be configured to inject carrier gas into the fluidizing chamber to fluidize particles within the fluidizing chamber. Fluidizing the particles at different carrier-gas pressures and/or flow rates can change the rate of particle delivery. For example, the metering assembly can include a metering opening and a regulator configured to change a steady-state pressure and/or flow rate of carrier gas entering the fluidizing chamber. Systems disclosed herein can include a controller configured to change a flow rate of particles through the metering opening.
