Abstract

A liquid metal knife cutting system comprises a cutting device, wherein the cutting device comprises a cutting nozzle and a rectification cavity communicated with the upper end of the cutting nozzle. An inlet pipe communicated with the pressure pump outlet through a hose is installed on the lateral wall of the rectification cavity, a miniature camera is installed on an observation hole on the lateral wall of the rectification cavity, and the pressure pump inlet is communicated with the liquid metal storage tank outlet. A workbench is arranged below the cutting nozzle, a recycle container is arranged below the workbench, a connection pipeline at the lower portion of the recycle container is communicated with the storage tank bottom, and a recycle pump is installed on the pipeline of the recycle container. A numerical control table comprises a processor and a data base, wherein the processor is used for calculating relevant cutting parameters in cutting, and the data base is used for recording the cutting parameters corresponding to cutting materials and cutting results. The cutting nozzle of the cutting device is coaxial with a motor shaft, and a motor receives operation commands given out by the numerical control table and controls a cutting path of the cutting nozzle of the cutting device according to the commands to complete cutting of a workpiece to be cut. The cutting system is high in cutting accuracy, stable, low in noise, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a high-pressure liquid metal knife cutting system, in particular to a high-pressure liquid metal knife cutting system which adopts liquid metal as a cutting working fluid and cuts workpieces after being pressurized by an electromagnetic pressure pump. Background technique [0002] Human beings have used the impact force of fluid since ancient times to manufacture water conservancy machinery such as waterwheels and water mills. And if the fluid is ejected from the high-pressure nozzle, a greater impact force will be generated. Inspired by this, former Soviet scientists developed high-pressure water jet cutting technology. Compared with electric saw, electric arc cutting and laser cutting, fluid cutting has many advantages. It is extremely fast and can cut various workpieces according to user needs; secondly, the processing is cold processing, so there is no need to worry about the burning and deformation of the workpiece cause...
