Device for forming bimetal composite pipe by spinning semisolid metal powder on outer wall of steel pipe

Abstract

The invention relates to a device for forming a bimetal composite pipe by spinning semisolid metal powder on the outer wall of a steel pipe. The device comprises a feeding device, a clamping device, spinning rollers, a hot melting head, a motor, a lifting device, a workbench, a buffer bearing pack, a tailstock supporting device and a heat preservation device. By adopting the three spinning rollers, the spinning efficiency is improved, meanwhile, uniform stress is guaranteed, and semisolid powder is uniformly spun on the outer wall of a metal pipe. The spinning rollers are designed to be taper,so that the forming resistance of a spinning device in the axial moving process can be effectively reduced, and it is guaranteed that the outer wall of the steel pipe is evenly covered with semisolidpowder. The lifting device is additionally arranged and can be adjusted according to different pipe diameters so as to machine different metal pipes. A spring is additionally arranged at the bottom of a first bearing seat, so that rigid impact between the steel pipe and the spinning rollers in the spinning process is avoided and reduced, and the surface appearance and the structure uniformity ofa spinning layer are guaranteed. In addition, the device is driven by the motor, and a lead screw is used for driving a frame to axially horizontally move at constant speed.

Description

technical field [0001] The invention relates to the technical field of bimetallic pipe compounding, in particular to a device for forming a bimetallic composite pipe by spinning semi-solid metal powder on the outer wall of a steel pipe. Background technique [0002] Due to its superior anti-corrosion and anti-oxidation properties, bimetal composite pipes have been widely used in marine engineering, energy, chemical and machinery manufacturing industries. As the application fields of composite pipes become more and more extensive, the requirements for metal properties and the performance and strength of the bimetallic joint surface are also getting higher and higher, so higher requirements are put forward for the processing and manufacturing process of bimetallic composite pipes. [0003] Bimetallic composite pipes are generally made of two metals with greatly different physical and mechanical properties. Therefore, bimetallic pipe composite molding is more difficult, so the ...

AI Technical Summary

Problems solved by technology

The performance of the composite pipe produced by the solid-solid process is greatly affected by the physical and mechanical properties of the two bimetallic composite pipes, and the strength of the joint surface is not guaranteed, while the liquid-solid production process equipment occupies a large area, and the equipment investment and maintenance costs are very high. high
