Abstract

The invention discloses a device used for electrolyzing and processing a double-faced trumped-shaped hole array in a thin walled cylinder. A tool negative pole is a hollow rotary cylinder which is provided with a liquid inlet hole and a liquid outlet hole. A workpiece positive pole, an axis and an non-contact ground sleeve are arranged on the outside of the tool negative pole. Two ends of a ringlike cavity formed between the tool negative pole and the workpiece positive pole are in motive seal through electric insulation motive seal pieces. Two ends of the tool negative pole are respectively connected with an electrolyte circulating filtration unit. A positive pole and a negative pole of an electrochemical machining power supply are respectively connected with the workpiece positive pole and the tool negative pole. Two carrier rollers which are parallelly arranged below the workpiece positive pole are in line contact with the workpiece positive pole. The carrier rollers are driven by a power source unit. Two parallel carrier rollers are used for supporting and locating the large draw ratio thin walled cylinder stably and reliably, workpieces have small deformation, the workpiece positive pole is in a rotary state in the process of processing, electrolytes in a small hole of the workpiece positive pole can drop automatically under the effect of gravity, thus benefiting removal of electrolysates in a blind hole and update of the electrolytes in the small hole.

Description

technical field [0001] The invention relates to an electrolytic machining device, in particular to a device for electrolytic machining of a double-sided horn hole array on a thin-walled cylinder. Background technique [0002] At present, in the fields of metallurgy, chemical industry, powder, biomedicine, automobile, mining, food and beverage, machinery, textile, papermaking, oil and gas and water treatment, aerospace and other fields, it is often applied to the filtration and screening process of substances. The application effect of filtration and sieving largely depends on the technical performance index of the filter (sieve) mesh. The application practice shows that the filter (screen) mesh with double-sided trumpet-shaped hole cross-section has the advantages of small accumulation pressure on the surface of the filter mesh, easy slag unloading and cleaning, not easy to block, long filtration cycle and service life, and easy maintenance. New development trend of high-pe...
