Description

Porous material manufacturing device based on metal chips Technical Field The utility model relates to the field of energy absorption structure manufacturing, in particular to a porous material manufacturing device based on metal scraps. Background In automobiles, aviation, rail transportation, ships, packaging, and protection engineering, porous materials have received much attention for their excellent specific strength and energy absorbing ability. The existing preparation methods of the porous metal material mainly comprise a powder metallurgy method, a melt foaming method, a gas injection method and the like. Although these methods can realize a high-performance porous structure, they are limited by cost and production efficiency, and conventional porous materials are difficult to apply on a large scale in engineering. A large amount of metal chips are generated in the machining process, and the metal chips have natural curled, flaky or spiral structures and have the potential of forming a three-dimensional supporting framework, and if the metal chips are reasonably treated, the metal chips can be directly used as raw materials for preparing porous structures, so that the high-value utilization of resources is realized, and the use cost of porous materials is obviously reduced. At present, research on recycling of metal scraps mainly focuses on smelting recovery and powdering treatment, and efficient manufacturing means for directly constructing a structured porous material aiming at geometric characteristics of the metal scraps are not available. Disclosure of utility model The utility model aims to provide a low-cost porous material manufacturing device, which can remarkably reduce the use cost of porous materials. The technical scheme is that the porous material manufacturing device based on the metal scraps comprises a device main body and two electrodes arranged at the upper end and the lower end of the device main body. The device comprises a device body, wherein an electrode water inlet and outlet are formed in the two ends of the electrode, an electrode water cooling cavity is formed in the electrode water cooling cavity, a plurality of partition plates are arranged in the electrode water cooling cavity, an electrode bolt and a nut are arranged at one end of the electrode, and the electrode is fixed in the L-shaped mounting groove through the electrode water inlet and outlet. The device is characterized in that current is applied to two sides of a metal chip stacking body, so that metal chip contact points (high in current density and high in resistance heat) generate heat to melt, and connection strength is generated after solidification. The device utilizes the natural curled structure of metal scraps to construct a three-dimensional porous framework, so that a novel low-cost porous material is formed. The cooling system ensures the temperature stability of the electrode in the processing process, and avoids the decrease of the conductivity of the electrode material caused by overheating. The device has simple structure and is suitable for industrial production. Compared with the traditional powder metallurgy or foaming method, the device has the advantages of simple process, low equipment cost, short processing period, high raw material utilization rate and the like, can effectively promote the recycling of metal scraps, and provides important technical support for the large-scale industrial application of the porous metal energy absorbing material.
