Abstract

The invention discloses an electrolytic machining system and an electrolytic machining method for a foamed aluminium buffering and energy adsorbing material. The electrolytic machining system comprises an electrolytic machining machine tool which is formed by a machining system, a control system, an electrolyte system and a fixture device. Firstly, after a foamed aluminium porous material to be machined is fixed, the distance between the foamed aluminium material and an electrode is regulated; and after each machining parameter is set, the electrolytic machining can be carried out. For the foamed aluminium porous material, compared with a conventional turning, planing and grinding scheme, the technical scheme disclosed by the invention overcomes the deformation and the breakage of the porous structure in the machining process.

Description

technical field [0001] The invention relates to the field of electrolytic machining, and more specifically relates to an electrolytic machining system and method for foamed aluminum buffer energy-absorbing materials. Background technique [0002] Aluminum foam is a light porous metal material with Al or its alloy as the matrix and contains a large number of pores. Its main structural characteristics are large pore size and high porosity. Structural and functional metallic materials. Aluminum foam has the characteristics of small specific gravity, light weight, strong heat resistance, high rigidity, etc., and also has the function of cushioning and energy absorption, and is increasingly valued by various fields such as packaging and transportation, military protection, aviation, and aerospace. Especially as a cushioning and energy-absorbing material, it has been widely used in the cushioning packaging of vulnerable items, the protection of important equipment such as satelli...
