Hot forming tube expanding machine

The main components of the pipe expander: the equipment mainly includes: the frame, the main cylinder support plate (including the main cylinder), the movable push plate, the front support plate, the automatic feeding system, the feeding roller table, the mold support, the intermediate frequency coil adjusting frame (including the intermediate frequency heating coil), the intermediate frequency power supply, the electrical control system and so on.

Hot forming pipe expanding machine is an important type in seamless steel tube production system, which is mainly suitable for the production of large diameter medium and thin wall steel tubes.Based on the results of spatial analysis and finite element simulation, the feed Angle, main deformation and additional deformation of the pipe expanding mill are analyzed, which can provide the basis for the variety development, process optimization, equipment transformation and equipment design of the similar mill.The analysis results show that: (1) The roll adjustment of the pipe expanding mill is different from that of the ordinary pipe rolling mill, but it has the same feed Angle as the ordinary pipe rolling mill.(2) Rolling Angle and roll translation are necessary conditions for the formation of feed Angle. The larger the roll Angle and the larger the roll translation distance, the larger the feed Angle.③ The wall reduction deformation is mainly transformed into the diameter expansion deformation, and the longitudinal deformation is very small.(4) The additional deformation of the pipe expanding mill is much smaller than that of the ordinary two-high cross rolling mill, and the torsional deformation is very small.Hot-forming pipe expanding machine is a non-standard product, there is no specified model size, can be directly customized according to customer needs.

Seamless thermal tube expanding machine

Medium frequency pipe expanding machine is a kind of seamless steel pipe thermal expanding process and thermal expanding machine, thermal expanding process steps are, first thermal expanding one end of seamless steel pipe, and then put an inner ring in the end, and then continue to expand the rest of the steel pipe after clamping the steel pipe.The hot expanding pipe machine includes a frame, a lifting roller table, a backstage trolley device, a locking clamping device, a jacking rod, a main transmission cylinder and an inner ring device.The invention has the advantages of simple equipment structure, reliable operation, high production efficiency, high rate of finished material, stable product performance, and the thermal expanding process and thermal expanding pipe machine of the invention are easy to realize continuous automatic production.Pipe expanding machine is non-standard product, there is no specific specification model, can be customized directly according to customer needs.

The equipment of the pipe expanding machine mainly includes: the frame, the main cylinder support plate (including the main cylinder), the movable push plate, the front support plate, the automatic feeding system, the discharging roller table, the mold support, the intermediate frequency coil adjusting frame (including the intermediate frequency heating coil), the intermediate frequency power supply, the electrical control system and so on.
