Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy-absorbing structure manufacturing, specifically to a porous material manufacturing device based on metal scrap. Background Technology
[0002] Porous materials have attracted widespread attention in automotive, aerospace, rail transportation, shipbuilding, packaging, and protective engineering due to their excellent specific strength and energy absorption capacity. Existing methods for preparing porous metallic materials mainly include powder metallurgy, melt foaming, and gas injection. While these methods can achieve high-performance porous structures, their limitations in cost and production efficiency hinder the large-scale application of traditional porous materials in engineering.
[0003] Machining processes generate a large amount of metal chips. These chips possess natural curled, sheet-like, or spiral structures, with the potential to form a three-dimensional supporting framework. With proper processing, they can be directly used as raw materials for preparing porous structures, thereby achieving high-value utilization of resources and significantly reducing the cost of using porous materials. Current research on metal chip recycling mainly focuses on smelting and powdering, lacking efficient manufacturing methods that directly construct structured porous materials based on the geometric characteristics of metal chips. Utility Model Content
[0004] The present invention aims to provide a low-cost porous material manufacturing device, which significantly reduces the cost of using porous materials.
[0005] The specific technical solution is as follows: a porous material manufacturing device based on metal scrap, comprising a device body and two electrodes installed at the upper and lower ends of the device body. The upper and lower ends of the device body are respectively provided with L-shaped mounting grooves, and the side wall of the device body is provided with a temperature measurement port; the electrodes are provided with electrode inlet and outlet water ports at both ends, and have an electrode water-cooling cavity inside; the electrode water-cooling cavity is provided with multiple partitions; one end of the electrode is provided with an electrode bolt and nut; the electrode is fixed in the L-shaped mounting groove through the electrode inlet and outlet water ports.
[0006] This device applies an electric current to both sides of a metal scrap accumulation, causing the metal scrap to melt at the contact points (high current density, high resistance heat), and then solidify to form a bond. The device utilizes the natural curled structure of the metal scrap to construct a three-dimensional porous framework, forming a novel, low-cost porous material. A cooling system ensures stable electrode temperature during processing, preventing overheating and a decrease in electrode material conductivity. The device has a simple structure, suitable for industrial production. Compared to traditional powder metallurgy or foaming methods, this device offers advantages such as simple process, low equipment cost, short processing cycle, and high raw material utilization. It can effectively promote the resource utilization of metal scrap and provide important technical support for the large-scale industrial application of porous metal energy-absorbing materials.

[0012] A porous material manufacturing device based on metal scrap includes a main body 1 and two electrodes 9. The main body 1 has L-shaped mounting grooves 2 at its upper and lower ends, and a temperature measuring port 3 on its side wall. The electrodes 9 have electrode inlet / outlet water ports 4 at both ends and an electrode water-cooling chamber 8 inside. The electrode water-cooling chamber 8 contains multiple partitions 7. One end of each electrode 9 has an electrode bolt 6 and a nut 5. The electrodes 9 are mounted at the upper and lower ends of the main body 1 by fixing the two electrode inlet / outlet water ports 4 within the L-shaped mounting grooves 2.
[0013] The temperature measurement port 3 is used to monitor the internal temperature of the device in real time. By adjusting the current according to the temperature, the temperature during the metal chip forming process is kept within a reasonable range. The partition 7 serves as a flow guide to enhance convective heat transfer. The external power supply is connected to the electrode 9 through the electrode bolt 6 and nut 5.
[0014] In the specific forming process, electrode 9 is first installed to the lower end of the device body 1 through the L-shaped mounting groove 2, and then metal cutting chips are filled into the inner cavity of the device body 1. Next, another electrode 9 is fixed through the L-shaped mounting groove 2 at the upper end of the device body 1. At this point, the upper and lower ends of the metal chip accumulation are in close contact with the upper and lower electrodes 9, respectively. An external power supply is connected to the electrodes 9 through electrode bolts 6 and nuts 5, and the cooling system is activated to ensure that the electrodes 9 are at a suitable temperature. Subsequently, power is applied. The current density at the metal chip contact point is much greater than that of the metal chips themselves, so the current flowing between the metal chips generates more heat at the metal chip contact point, causing the metal chips to partially melt and solidify together.
[0015] The above device enables rapid and efficient manufacturing of porous materials based on metal scrap, improves the resource utilization rate of metal scrap, and has a simple structure and excellent cooling effect, making it suitable for industrial production applications.
