Used for produce diameter of 914mm carbon steel and alloy steel pipe hot induction tube expander
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.
|Thrust(t)||Max working feed
|M.F power(kw)||Max working
|Max wall thickness of finished pipe(mm)|
The total distance of the tube expander is 10-14.5 meters. The feeding and unloading mechanism of the tube expander adopts rollers to drive the steel tube forward to finish feeding.If power supply is installed in the front end of the tube expander, if coil is placed on the adjustment rack of if coil, the core reamer mold is put in place, the original tube is put in, the water pump and if power supply are turned on, and if power is adjusted, the core of the tube can be adjusted Mould and tube heating.Start the tube machine again, you can officially expand the tube.The intermediate frequency coil, compensation resonant capacitor, reactor and other components of the tube expander need to be cooled by circulating water.The electrical control part of the tube expanding machine is installed in the electric control box, and the travel switch is installed at both ends of the tube expanding machine.
Special equipment for steel tube hot hole enlargement, 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 various non-standard steel tube expanding needs, is currently the main production process of large diameter steel pipe.It has been widely used in military industry, power plant construction, aerospace industry and Marine industry equipment manufacturing industry, making a great contribution to China's steel pipe industry and energy construction.
The equipment is used in the production of seamless steel pipe, straight seam welded pipe, coil pipe and so on.Expandable steel tube varieties are: various carbon steel, alloy steel, stainless steel and so on.
The expanding equipment mainly includes: the frame, the main oil cylinder support plate (including the main oil cylinder), the movable push plate, the front support plate, the automatic feeding mechanism, the discharging 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.
