Hot forming tube expanding machine

Main components of the tube expanding machine: the equipment mainly includes: the frame, the main oil cylinder support plate (including the main oil cylinder), the moving push plate, the front support plate, the automatic feeding mechanism, the cutting roller table, the mold support, the intermediate frequency coil adjustment frame (including the intermediate frequency heating coil), the intermediate frequency power supply, the electrical control system and so on.

Thermoforming pipe-expanding machine is seamless steel tube production system is an important kind of models, mainly is suitable for the production of large diameter thin-walled steel tube. The spatial analytical and finite element simulation results, the skew rolling pipe-expanding machine sent to Angle, the main deformation and deformation are analyzed, the development of varieties, to the similar unit process optimization, equipment modification and equipment design. Analysis results show that (1) skew rolling roll adjustment interchanged with normal skew rolling mill is different, but with normal skew rolling mill has sent to Angle;(2) rolling Angle and roll translation are the necessary conditions for the formation of feeding Angle of the tube mill.(3) the reduction of wall deformation is mainly transformed into diameter expanding deformation, the longitudinal deformation is very small;(4) the additional deformation of the rolling mill is far less than the ordinary two-high rolling additional deformation, and the torsion deformation is very small.
