Suction liquid discharge assisted double-narrow-slit electrolytic cutting machining device and method

Abstract

The invention relates to a suction liquid discharge assisted double-narrow-slit electrolytic cutting machining device and belongs to the field of electrolytic machining. The suction liquid discharge assisted double-narrow-slit electrolytic cutting machining device is characterized in that axial and radial suction devices are additionally arranged on a tube electrode cutter, the flow speed of electrolyte in the machining area is increased, so that products are rapidly discharged, and the machining quality is improved; double narrow slits are formed in a tube electrode, so that the machining face, in the advancing direction, of the cutter is more smooth. The suction liquid discharge assisted double-narrow-slit electrolytic cutting machining device comprises a suction pump, an insulated suction pipe, a double-narrow-slit tube electrode, a power source, an electrolyte circulating system, an electrolysis machining machine tool and a work fixture. The suction liquid discharge assisted double-narrow-slit electrolytic cutting machining device has the important significance in improving the flow speed of the electrolyte, rapidly discharging the products and ensuring one-time electrolytic cutting super-thick workpieces (with the thickness larger than 100mm).

Description

technical field [0001] The invention relates to a double narrow slit liquid spraying electrolytic cutting processing device assisted by suction and discharge, which belongs to the field of electrolytic processing. Background technique [0002] The electrolytic jet cutting processing technology adopts the electrolytic method of spraying liquid inside the tube electrolysis to remove the material. The cathode tool cuts the workpiece according to the specified path under the control of the numerical control system. noodle. Due to the non-contact processing, there is no cutting force during the processing, the tool will not be worn out, and theoretically it can be used unlimited times.

Problems solved by technology

[0003] In aerospace and other fields, some key connecting parts are mostly made of difficult-to-machine materials such as titanium alloys. The profile is relatively complex, and the amount of material removal is also large. The traditional cutting tool wears seriously and the processing technology is also very complicated.

There are recast layers and micro-cracks on the surface of the workpiece processed by traditional wire-cutting technology and laser processing technology, and every feature of traditional wire-cutting technology needs to be threaded again, resulting in low processing efficiency; although electrolytic wire-cutting technology processes The processed surface has no recast layer and microcracks, but the processing speed is extremely low, and multiple wire threads are required to complete the processing of mu
