Ice crystal water-jet cutting machine technology

Abstract

The invention discloses ice crystal water-jet cutting machine technology. At present, for the water-jet cutting machines widely used in China and foreign countries, a special sand feeding system feeds an abrasive material into a high-pressure water jet to cut and process a high-hardness material; the abrasive material flowing at a high speed fatally damages a high-pressure pipeline through which the abrasive material flows and a nozzle and causes accuracy deviation of cut workpieces, and the most headache core technical problems which puzzle producers and users of high-pressure water cutting machinery are not effectively solved all the time. In the ice crystal water-jet cutting machine technology, a circular spray type conflux spray nozzle which is initiated in the invention is arranged on the high-pressure water cutting machinery; water which does not contain salts is cooled forcedly in the high-pressure pipeline through a temperature control device and a liquid temperature range which keeps the water close to a condensation point and flowing is dynamically controlled; and the water jet which is sprayed from a nozzle and is close to a freezing point can form a high-hardness ice crystal bundle water jet which carries huge energy of a speed instantly. The ice crystal water-jet cutting machine technology is brand new technology in which another physical phase ice crystal of water replaces the conventional abrasive material to efficiently cut the high-hardness material, and excessive independence on an abrasive material feeding system is eliminated, so that the ice crystal water-jet cutting machine is the water water-jet cutting machine of real meaning; flow with which the abrasive material is not mixed hardly wear the high-pressure pipeline through which the flow passes and the nozzle and the cost consumption of the abrasive material is avoided, and the service life of the water-jet cutting machinery is greatly improved.

Description

Technical field [0001] The invention relates to ice crystal water jet technology, which is a brand new technology in the field of high-pressure water jet machinery. Background technique [0002] At present, water jets widely used at home and abroad rely on special sand supply systems, adding abrasives to high-pressure water jets to cut and process high-hardness materials; high-speed flowing abrasives will not only affect the high-pressure pipelines and The nozzle causes fatal wear, and at the same time, it will cause deviations in the accuracy of the workpiece to be cut. The high-hardness diamond wear-resistant nozzle is used for water jets. When the overall service life is the longest, it is worn out and completely scrapped in less than 100 hours; as The abrasives of consumable materials are not cheap, which makes the cost high. Due to the simple reason of high cost, there is no price advantage, which reduces the competitiveness of waterjet users' products in the market; T...

[0002] At present, water jets widely used at home and abroad rely on special sand supply systems, adding abrasives to high-pressure water jets to cut and process high-hardness materials; high-speed flowing abrasives will not only affect the high-pressure pipelines and The nozzle causes fatal wear, and at the same time, it will cause deviations in the accuracy of the workpiece to be cut. The high-hardness diamond wear-resistant nozzle is used for water jets. When the overall service life is the longest, it is worn out and completely scrapped in less than 100 hours; as The abrasives of consumable materials are not cheap, which makes the cost high. Due to the simple reason of high cost, there is no price advantage, which reduces the competitiveness of waterjet users' products in the market; The most critical core technical problems for producers and users of water cutting machinery have never been effectively solved in history

[0004] The purpose of the ice crystal waterjet technology provided by the present invention is to solve the problem of the previous high-pressure water jet cutting machine, which must rely on the sand supply system to add abrasives to the high-pressure water jet when cutting and processing high-hardness materials; Due to the problem of scrapping due to wear and tear, as well as the impact of high maintenance costs and reduced cutting accuracy caused by the above reasons, the application of the present invention is expected to completely solve the above technical problems
