A pre-mixed abrasive jet hot-melt cutting equipment based on arc heat effect

Abstract

The invention discloses melt cutting grinding material jet flow equipment for a pre-heat mixed grinding material jet flow based on the function of the arc heat effect. The equipment comprises a portable generator, a high-pressure pumping station, a target and a hot melt cutting device. The hot melt cutting device comprises a cutting nozzle and tilting hot melt nozzles; the cutting nozzle is arranged vertically; an adjusting fixing disc is mounted in the middle of the cutting nozzle through a thread; annular gear rings and annular limit blocking rings are arranged at the outer circle of the adjusting fixing disc; and the annular gear rings are further symmetrically distributed on the two sides of the adjusting fixing disc and located on the inner sides of the annular limit blocking rings. Adjusting fixing nuts are mounted on the two sides of the adjusting fixing disc correspondingly; and further mounted in the middle of the cutting nozzle. It can be realized that a position to be cut of the target is always under the function of the arc heat effect, the working pressure of steel cutting is greatly reduced, the cutting quality of the target cutting end face is obviously improved, and it is guaranteed that the target to be cut is under the function of the arc heat effect.

Description

technical field [0001] The invention relates to the technical field of abrasive water jet mechanical equipment design, in particular to a pre-mixed abrasive jet hot-melt cutting equipment based on arc heat effect. Background technique [0002] The water jet is a high-speed water stream of different shapes formed by the nozzle, and the flow rate of the jet depends on the pressure drop before and after the nozzle outlet section. Water jetting is the simplest form of energy transformation and application. Usually, the power-driven pump completes a suction and discharge process of water, pumps a certain amount of water to the high-pressure pipeline, and makes it reach the nozzle with a certain amount of energy. The hole diameter of the nozzle is required to be much smaller than that of the high-pressure pipeline, so this certain amount of water reaching the nozzle must be accelerated if it wants to flow out of the nozzle hole. In this way, the water that accelerates condensati...

Problems solved by technology

[0003] However, the existing water jet equipment cannot reduce the working pressure of cutting steel, improve the cutting quality of the target cutting end face, reduce the subsequent finishing process, and reduce the processing cost. Some water jet equipment cannot adjust the relative position of the adjustment plate and the adjustment seat. , it is difficult to ensure that the inclined hot-melt nozzle is directly in front of the trajectory of the cutting nozzle, and it is impossible to ensure that the target is under the effect of arc heat; some water jet equipment cannot limit the movement track of the adjustment plate and the adjustment seat; it is difficult to ensure that the inclined hot-melt nozzle and cutting nozzles are within the proper target distance range
