Preparation method of efficient explosive composite pipe rod based on water pressure

Abstract

The invention provides a preparation method of an efficient explosive composite pipe rod based on water pressure. The preparation method comprises the following steps: coaxially arranging a to-be-composited plate rod 1, a to-be-composited pipe 2, a small PVC pipe 1, a large PVC pipe 2, a to-be-composited pipe 3 and a to-be-composited pipe 4 from inside to outside, and arranging explosives and detonators among the PVC pipes to form an explosive device; filling water among the to-be-composited pipe 2, the explosive device and the to-be-composited pipe 3 to construct a water environment; and detonating the explosive device to weld and combine a to-be-composited material to obtain a group of explosive composite pipes and a group of explosive composite rods. According to the preparation method, high pressure generated by explosive explosion is transmitted through the water environment to realize welding of the to-be-composited materials; compared with a traditional composite technology, the preparation method of the efficient explosive composite pipe rod based on water pressure has the advantages that composite processing of thin-walled pipes can be realized, and ablation damage of high temperature generated by explosive explosion to the surface of the to-be-composited pipe is effectively avoided; and the sizes of the to-be-composited materials can be freely adjusted through addition of the water environment, the operability is high, and the energy utilization rate of the explosives is further increased.

Description

technical field [0001] The invention belongs to the field of explosive welding and relates to a method for preparing a high-efficiency explosive composite pipe rod based on hydraulic pressure. Background technique [0002] Multimetal composites are composite materials made of two or more different metals, which have high mechanical properties, excellent corrosion resistance and low density. In fact, a single metal material cannot meet the needs of industrial production for multi-metal properties, so the use of multi-metal composite materials occupies an irreplaceable part in the industry. Such as multi-metal composite rods and multi-metal composite tubes, which have important value applications in automobile manufacturing, aerospace and other industries that require economical energy consumption and environmental friendliness. [0003] Explosive welding is one of the effective methods for preparing multi-metal composite materials. It accelerates the cladding material throug...

Problems solved by technology

However, there are still several deficiencies that need to be solved urgently: traditional explosive welding is accompanied by serious noise and dust pollution in the production process, and the high temperature generated by explosive explosion often causes ablation damage to the surface of composite materials, affecting product quality; During the process, the size of the pipes and rods to be composited cannot be adjusted in time according to the actual situation, and the operability is low; only one set of composite materials can be produced in one detonation, resulting in a low utilization rate of explosive energy
