Problems solved by technology
However, due to the limitations of the post-mixing technology itself, it is difficult to achieve the requirements of precision machining. For this reason, the front-mixing water jet cutting technology is developing rapidly to make up for the deficiencies of water jet technology in the field of precision / ultra-precision machining
At present, the pre-mixed water jet cutting is almost always started and paused by controlling the start and stop of the motor and the high-pressure pump, and it is impossible to realize the intermittent cutting process without stopping the pump.
This is not conducive to the improvement of the precision of the pre-mixed water jet cutting technology and the realization of automation

The invention discloses a continuous premixed abrasive jet cutting device, belonging to the technical field of water jet cutting. The device includes a nozzle and an abrasive mixture fluid high pressure pipeline, and also includes a first main runner stop valve, a second main runner stop valve and an overflow valve. The abrasive mixture fluid high pressure pipeline is connected with the nozzle through the first main runner stop valve and the second main runner stop valve, an abrasive mixture fluid overflow pipeline is connected with the abrasive mixture fluid high pressure pipeline through the overflow valve, and the first main runner stop valve, the second main runner stop valve and the overflow valve are all connected with a compressed air pipeline. Thus, processes of fast cutting feed at the status of non-cutting, breakpoint jumping during hole machining, station conversion during multi-station machining, etc. can be achieved, further improving the practicality of premixed water jet cutting technology, and enabling full automation of parts machining to be achieved.
Description
Technical field [0001] The invention relates to a pre-mixed abrasive jet continuous cutting device, which belongs to the technical field of water jet cutting. Background technique [0002] At present, the abrasive water jet cutting technology is mainly divided into two forms: post-mixing and pre-mixing, among which the post-mixing abrasive water jet has been automated. However, due to the limitations of the post-mixing technology, it is difficult to achieve the requirements of precision machining. Because of this, the front-mixing water jet cutting technology is developing rapidly to make up for the lack of water jet technology in the field of precision / ultra-precision machining. At present, the pre-mixed water jet cutting is almost always realized by controlling the start and stop of the motor and the high-pressure pump to start and pause the cutting work, and it is impossible to realize the intermittent cutting process without stopping the pump. This is not conducive to the im...
