Definitions

  • Another object of the present invention is to propose an apparatus for water jet cutting that is simple to produce, therefore inexpensive, and that requires limited maintenance.
  • Tests carried out by the applicant show that the apparatus thus configured guarantees, with the same water pressure and the same type and amount of abrasive material, an increased cutting depth and improved surface finish (i.e., less roughness) relative to a conventional system of AWJ type.
  • the more orderly flow of the abrasive particles inside the focusing tube allows a reduction of the wear of this component relative to an aforesaid AWJ system.
  • the apparatus thus configured is particularly effective to carry out continuous or, in any case, lengthy machining operations, as it allows an abrasive material in suspension with constant properties to be fed to the source throughout the whole of the machining process.
  • a recovery and recycling system of the abrasive material that includes at least:
  • the abrasive material most widely used for water jet cutting is garnet, well known to those skilled in the art. While on the one hand this material guarantees excellent performance, due to its high level of hardness and resilience, on the other hand it is particularly costly. In fact, it is estimated that, on average, the costs for purchasing garnet abrasive can represent up to 40% - 60% of the operating cost of the apparatus.
  • the particles of the correct size which are therefore recyclable, are dried and stored to be re-introduced into the machining cycle.
  • said fluid is a gelatinous substance.
  • the step of dosing and subsequent mixing of the water, of the gelling agent and of the abrasive particles, earned out in the mixing device ensures that said abrasive material in suspension has the exact concentration of abrasive particles desired, guaranteeing constant quality and repeatability of the cutting operations.
  • the step of preparing the abrasive material in suspension comprises the mixing of water, at least one gelling agent, said wet or dry abrasive particles, or both wet and dry abrasive particles.
  • Said pumping means are generally configured to convey the process water at a pressure typically between 3000 and 6000 bar.
  • said mixing device 24 provided with agitator means to mix the abrasive particles and the liquid or gelatinous substance to form the abrasive material in suspension 21 .
  • said mixing device 24 is in communication with the tank 22.

Abstract

La présente invention concerne un appareil de découpe à jet d'eau comprenant : une source d'eau (2); - des moyens de pompage (4), en communication avec la source d'eau, pour générer un écoulement d'eau à haute pression; un réservoir (22) contenant un matériau abrasif en suspension (21), dans lequel ledit matériau abrasif en suspension comprend un fluide et des particules abrasives dispersées de manière homogène dans ledit fluide; et - une tête de coupe (10) en communication fluidique avec lesdits moyens de pompage (4) et ledit réservoir (22) du matériau abrasif en suspension (21), ladite tête de coupe comprenant une chambre de mélange (12); ledit réservoir du matériau abrasif en suspension (21) étant en communication avec ladite tête de coupe (10) au moyen d'un canal d'entrée abrasif (23) et ladite tête de coupe étant configurée pour générer une pression de vide qui tire le matériau abrasif en suspension (21) à travers ledit canal d'entrée d'abrasif (23) vers la chambre de mélange (12) pour mélanger le matériau abrasif en suspension et l'eau à haute pression et former un jet d'eau et d'abrasif (15). La présente invention concerne en outre un procédé de génération d'une découpe à jet d'eau pouvant être mis en œuvre avec ledit appareil.
