A device and method for gap-adjustable curved hole electrolytic machining

Abstract

The invention discloses a gap adjustment type bent hole electrochemical machining device. The device comprises a cathode head; the cathode head is provided with a through liquid hole communicating upand down; the outer side of the through liquid hole is provided with several gap adjustment mechanisms arranged at intervals along the circumferential direction; each gap adjustment mechanism comprises a pressure cavity and a gap adjustment head; a plug is arranged above the pressure cavity; the plug is provided with a through hole penetrating up and down; the upper end of the through hole is connected with a pressure pipe, and the lower end of the through hole is connected with the pressure cavity; one end of the gap adjustment head is limited in the pressure cavity and can move up and down,and the other end of the gap adjustment head movably penetrates out of the cathode head from the bottom of the pressure chamber; electrolyte enters a machining gap from the through liquid hole and flows under the action of an electric field, and the extension length of the gap adjustment head is controlled by adjusting the magnitude of the output pressure in each pressure pipe, so that bent hole machining with different bending directions and different radii of curvature can be carried. The gap adjustment type bent hole electrochemical machining device and a method of the invention can realizearbitrary adjustment of the machining curvature radius and ensure high-precision curvature machining.

Description

technical field [0001] The invention relates to an electrolytic machining device and method, in particular to an electrolytic machining device and method for machining bent holes. Background technique [0002] Many existing mechanical parts and components require curved hole structures, for example: in the structural bending of mold cavities (especially multi-cavity) and the cooling system design of die-casting molds, the defects of traditional linear coolant channels are becoming more and more prominent. If the coolant channel can be distributed according to the shape of the mold cavity, it can be cooled quickly and fully, so as to ensure uniform temperature in the cavity and core, and the temperature control of the mold can be more effectively carried out during the injection molding and die-casting process, and effectively improve Product quality and production efficiency; in the oil circuit design of some hydraulic components, in order to reduce resistance and avoid turn...
