For the manufacture of alloy steel elbow and steel tube expanding machine

Medium frequency tube expanding machine is used in the production of seamless steel pipe, straight seam steel pipe, coil pipe and other steel pipe.Expandable steel tube variety, all kinds of carbon steel, alloy steel, stainless steel and so on.
Specification: diameter: 89*-1420mm, wall thickness: 30-150mm, length: 3-24m.Various materials of steel tube :(p91-92 / t91-92, q235.q345.q45 #. A106b-c.12CrMOV).
Intermediate frequency tube expanding machine mainly includes: machine base, main oil cyIntermediate frequency tube expander is a special fitting equipment for hot expansion of steel pipe.Mainly for domestic large diameter steel pipe production cannot meet the demand of market and all kinds of steel pipe specification is not complete, meet the needs of small batch more varieties of steel pipe production, can satisfy the different material steel pipe hole enlargement and enlargement of head all kinds of non-standard steel tube company, is currently the main production process of large diameter steel pipe, is now widely used in aerospace industry equipment manufacturing, for the country's steel pipe industry and made great contribution to energy construction.

linder support plate, movable push plate, front support plate, automatic feeding mechanism, roller table, mold support, intermediate frequency coil adjusting frame including intermediate frequency heating coil, intermediate frequency power supply, electrical control system and so on.

Compared with manual heating of steel pipe, the intermediate frequency tube expander simplifies the process and reduces labor cost and time.Increased production efficiency.
The equipment consists of the main engine of the hydraulic pusher, the automatic feeding and discharging mechanism, the hydraulic pump station, the tube adjusting device, the operating platform, the motor control cabinet, the intermediate frequency power supply, the compensation capacitor, the water cable, the intermediate frequency coil adjusting frame, the reactor and other components.Medium frequency tube expanding machine has an advantage is the intelligent constant temperature system, can effectively avoid due to human factors caused by the temperature is too high to pull down the quality of the steel tube and die scrap, or the temperature is too low to cause the rod and die fracture phenomenon, put an end to the unsafe factors.
Tube expander is a special equipment for hot diameter expansion of steel tubes. It is designed for the production of large diameter seamless steel tubes and the specification is not enough to meet the domestic and foreign market demand.It is the main production technology of large diameter steel tube at present.The main power source of the equipment is the parallel equal-speed push machine with two or four oil cylinders. The valve platform of the pump station adopts the integrated form. The power of the medium-frequency heating power supply, the thrust and stroke of the oil cylinder are set according to the outer diameter and length of the steel tube to be expanded.
