Abstract
The present invention relates to a device for forming bimetal composite pipe by spinning semisolid metal powder on outer wall of steel pipe, which comprises feeding device, clamping device, spinning roller, hot melting head, motor, lifting device, work table, buffer bearing pack, tailstock support device and heat preservation device. According to the invention, three spinning rollers are adopted, so that spinning efficiency is increased, uniform stress is ensured, and the semisolid powder is uniformly spun on the outer wall of the metal pipe; the spinning roller adopts a taper design, so that forming resistance of the spinning device in the axial moving process can be effectively reduced, and the semisolid powder is uniformly covered on the outer wall of the steel pipe; the lifting device is added, so that the lifting device can be adjusted according to different pipe diameters to process different metal pipes; spring is additionally arranged at the bottom of the first bearing seat to avoid and reduce rigid impact between the steel pipe and the spinning rollers in the spinning process and ensure uniform surface appearance and structure of a spinning layer; in addition, the device i…
