Embodiment Construction

[0013] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Provided in conjunction with the accompanying drawings, a method for preparing a high-quality explosive composite pipe includes the following steps:

[0015] 1) From the inside to the outside, the composite pipe 1, the composite pipe 2, the small-diameter pvc pipe 4-1, and the large-diameter pvc pipe 4-2 are coaxially arranged in sequence, and the pcv pipe 4-1 and the pvc pipe 4-2 Explosives and detonators are filled between them to make the explosive device 4 of the pipe to be welded;

[0016] 2) Fill water between the pipe to be composited 2 and the explosive device 4 to construct a water environment 3;

[0017] 3) Detonate the explosive device 4, and transmit the high pressure generated by the explosion through the incompressible water environment 3, so as to firmly weld the pipes to be composited to obtain an explosi...

Abstract

The invention provides a preparation method of a high-quality explosive composite tube. The preparation method comprises the following steps: coaxially arranging a to-be-compounded tube 1, a to-be-compounded tube 2, a small-radius PVC tube 1 and a large-radius PVC tube 2 from inside to outside, and filling space between the PVC tubes with an explosive and a detonator to prepare an explosive device of materials to be welded together; filling space among the to-be-compounded tubes and the explosive device with water to construct a water environment; and detonating the explosive device and welding and combining the to-be-compounded tube by utilizing water pressure to obtain a high-quality explosive composite rod tube. The invention provides the method for compounding the tubes by transferring high pressure generated by explosive explosion via a water medium, so dust and noise pollution in the preparation process is effectively reduced, and environmental protection and safety are taken into consideration while production quality is ensured; a water environment interlayer is reasonably utilized, so the size of the to-be-compounded tubes can be randomly selected as required; compared with a traditional technology, the operability of the method is higher, and the tubes are prevented from being damaged due to high temperature generated by explosive explosion; and the defect that composite machining of thin-wall tubes is difficult to achieve through traditional explosive welding is overcome.

Description

technical field [0001] The invention belongs to the field of explosive welding and relates to a preparation method of a high-quality explosive composite pipe. Background technique [0002] Explosive welding is a common welding method for compounding various metal materials with the same or different properties. This method uses the energy of explosive explosion to accelerate the cladding material, so that the cladding material collides with the base material at high speed in a short time and realizes metallurgical welding. combined. Explosive welding is characterized by its low production cost and good welding quality, and it can produce a wide range of bimetallic and even multimetal composite materials on the premise of keeping the physical and chemical properties of the composite metal unchanged. Bimetal composite pipe is widely used in aerospace, machinery manufacturing, petrochemical engineering and other industrial fields. It combines the physical and chemical properti...
