AI Technical Summary

Benefits of technology

The technical effect of this patent is to provide a water-jet cutting system that is cheaper and requires less maintenance than existing systems.

Problems solved by technology

The significant length of the flexible conduits, in some cases more than 10 m, nevertheless entails significant load losses.
Accordingly, it is necessary to oversize the intensifier resulting in increased purchase, operation and frequent maintenance costs that are required to replace the components of the intensifier that are subjected to fatigue.

Embodiment Construction

[0018]With reference to FIGS. 1 to 3, a water jet cutting system 1 is configured for cutting a raw object (not shown), by abrasion and erosion, to obtain therefrom a finished product of desired shape.

[0019]The cutting system 1 includes a dispensing device 2, including one or more cutting heads 3, configured for dispensing a jet of water onto the object to be cut.

[0020]Each of the one or more cutting heads 3 includes, in one embodiment of the invention:[0021]an inlet, which is not shown, for receiving pressurized water;[0022]a primary nozzle, which is not shown, for transforming the energy of the pressurized water into kinetic energy;[0023]an inlet, which is not shown, for receiving abrasive material, for example an abrasive powder;[0024]a mixing chamber, which is not shown, for mixing the pressurized water and the abrasive material; and[0025]a focusing nozzle, which is not shown, for focusing the jet formed by the mixture of water and abrasive material on the object to be cut.

Abstract

A water jet cutting system includes a supporting surface for supporting an object to be cut, a dispensing device for dispensing a jet of water against the object to be cut, a pressurized water generating apparatus in fluid communication with the dispensing device for supplying pressurized water to the dispensing device, and a support including a crosspiece positioned above the supporting surface for supporting the dispensing device and the pressurized water generating apparatus.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Patent Application No. IT-102017000114587 filed on Oct. 11, 2017. The entire content of this application is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The invention relates to a water-jet cutting system.[0003]Initially, water-jet cutting technology involved dispensing a jet of water at very high speed through a small diameter nozzle. This enabled a variety of materials to be cut, including: cardboard, fabric, nylon, plywood, polyethylene, food products, etc.[0004]Subsequently, in order to improve cutting capability, an abrasive powder was added to the water. This enabled water-jet cutting technology to be used to cut materials that were harder than the previously mentioned materials, such as, for example: glass, marble, steel, composite materials, etc.[0005]Current water-jet cutting systems include, inter alia, a hydraulic intensifier to generate pressurized water, an attenuator f...
