What are the characteristics of IF tube expander

What are the characteristics of IF tube expander

The SCR, IF coil, compensation resonant capacitor, reactor and other components of IF power supply of IF tube expanding machine need water cooling.

The electrical control part of the IF tube expanding machine is installed in the electric control box. The travel switch is installed at both ends of the equipment's travel. After the push plate moves in place, it will stop automatically.

A kind of hydraulic pipe equipment, used for seamless steel pipe diameter expansion, to meet the shortage of large diameter steel pipe in the market. The pushing system of the pipe expanding machine is driven by hydraulic cylinder. According to the different pushing force, two cylinders or four cylinders can be used. Generally, two - step propulsion is adopted to save cylinder travel.

The total advance stroke of the IF tube expanding machine is 10-14.5m. The loading and unloading structure of the tube expanding machine is to use roller to drive the steel pipe forward to complete the loading and unloading.

The IF power supply of the IF tube expanding machine is installed at the front end of the equipment. The IF coil is placed on the IF coil adjusting frame, and the tube expanding core head mold is equipped. The original pipe is put in, the water pump and IF power are started, and the IF power is adjusted to heat the tube expanding core head mold and pipe. Then start the pipe machine, you can officially expand the pipe.

The tube expanding machine adopts medium frequency power induction heating, the wire trap is outside the steel tube, the steel tube is coated with lead powder before pushing, and it is transported into the hydraulic pushing machine through the feeding rack. After expanding the diameter, it is output through the feeding rack.

Main 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 station construction, aerospace industry and Marine industry equipment manufacturing, and has made a great contribution to the user's steel pipe industry and energy construction.

The equipment is used in the hot expansion of seamless steel pipe, straight seam welded pipe, coil pipe and other steel pipe production. Extendable steel pipe varieties are: all kinds of general carbon steel, alloy steel, stainless steel and so on.

Specifications of hot expanding steel pipe: diameter φ60 ~ φ1420mm, wall thickness 3 ~ 120mm, length 3 ~ 24m. Can expand the production of various materials of steel pipe (such as P91-92/T91-92, Q235, Q345, 45#, A106B-C, 12CrMoV).
