A device for forming a bimetal composite pipe by spinning semisolid metal powder on an outer wall of a steel pipe, comprising a feed device, a lifting device, a spinning device, a buffer bearing pack, a tail support device and a heat preservation cover, wherein
- the feed device comprises a feed motor, a bearing seat, a first coupling, a first lead screw and a first lead screw nut, wherein the feed motor is connected with the first lead screw through the first coupling, both ends of the first lead screw are supported through bearings, the first lead screw is connected with a work table, and the feed motor drives the first lead screw to rotate so as to drive the first lead screw nut and the work table to axially translate;
- the working table is provided with a lifting device, an isolation cover filled with protective gas and a spinning device, and the spinning device comprises a spinning roller, an electromagnetic induction heating device and a buffer bearing seat so as to uniformly spin semisolid powder on the outer wall of the steel pipe;
- the lifting device comprises a lifting motor, an upper bearing seat, a second coupling, a second lead screw, an upper frame, a lower bearing seat, a second lead screw nut and a plate, the second lead screw is connected with the lifting motor through the second coupling, and the second lead screw drives the second lead screw nut and the frame to move up and down under the drive of the lifting motor, to install and adjust the pipe;
- the buffer bearing pack comprises a lightweight spring, a first bearing, a check bolt, a buffer bearing seat and a bearing end cover, the buffer bearing seat is fixedly connected with the work table through the check bolt, the lightweight spring is sleeved on the check bolt coaxially, a groove corresponding to the lightweight spring is formed in the bottom of the buffer bearing seat, the first bearing is installed in the buffer bearing seat, which is axially positioned and fixed through the bearing end cover;
- the tail support device comprises a tail support frame, a tail bearing seat, a tail supported roller and a second bearing, wherein both ends of the tail supported roller are supported by the second bearing, the second bearing is arranged in the tail bearing seat, the tail support frame is fixedly connected with the work table, and the tail bearing seat is fixedly connected with the tail support frame;
- the heat preservation cover is connected with a guide rail through a pulley.
