Description

Technical Field

[0001] The utility model relates to the field of cutting equipment, and more specifically, to a gantry type numerically controlled water jet cutting machine. Background Art

[0002] Water jet cutting uses a nozzle to generate a high-pressure water jet carrying fine abrasive particles for cutting. This method is very effective in cutting both metal and non-metal materials. According to the cutting method, "water jet cutting" is divided into two types: sandless cutting and sand-added cutting. In aviation industry manufacturing, cutting is mostly done by adding pomegranate sand. Pomegranate sand has high hardness and sharp corners. It has good cutting force when cutting and can cut any material. If there is no pomegranate sand, both the cutting accuracy and depth will be greatly reduced. Experiments show that if pomegranate sand is not added, only 3 mm titanium plates can be cut, and the cut is jagged. After adding pomegranate sand, 30 mm titanium plates can be cut with greatly improved accuracy.

[0003] Patent No. CN219562685U discloses an ultra-high pressure water jet cutting device, including a cutting component, a solid-liquid separation component and a collecting component. The cutting component includes a fixed base frame, the inner side of the fixed base frame is provided with a workpiece support plate, and a water jet cutting device is arranged above the workpiece support plate; when it is necessary to clean the precipitated sand and impurities, the started servo motor will drive the threaded screw to rotate reciprocatingly, and at the same time, with the cooperation of the positioning guide rod and the fixing nut, the support plate drives the scraper to move back and forth, and the sand and impurities precipitated at the bottom of the box are pushed to the guide port through the rubber scraper, and then fall into the collection box, thereby achieving the effect of solid-liquid separation. At the same time, the cleaner water after separation can be discharged to the collection device through the drain valve, and can be used for secondary cutting, thereby achieving the purpose of water recycling, which not only protects the environment but also reduces the waste of water resources.

[0004] In the above patent, the inventor believes that when the patent is in use, wastewater will be generated when the water jet cutting device cuts materials. The wastewater includes water, abrasives and cutting powder. At present, when the water jet cutting equipment separates the abrasive, the sedimentation method alone cannot guarantee the thoroughness of the separation of the abrasive and the cutting powder, which cannot meet the recycling and reuse of the abrasive.
