Hot forming tube expanding machine

1, in hot forming pipe-expanding machine production automatic control medium frequency power supply will be steel tube heated to the required temperature and constant, effectively avoid the human factors caused by the steel tube burnt (high temperature) to produce fall and die scrap steel pipe products, at the same time avoid the temperature is too low and the thermal expansion unit thrust lever or die fracture is caused by the rising.

2. Compared with manual operation, the steel pipe is heated and the hot-forming pipe expanding machine saves energy. It simplifies the operation procedure and reduces the labor cost, so that one operator can monitor at most 10 pipe expanding units for normal production and pipe expanding

3, each unit set up two temperature measuring points and automatic temperature control, according to the different type of preset steel pipe heating temperature, choice for expanding tube heating and constant temperature, and the real-time display and record, can print and save heating temperature parameters in real time curve and history curve, which guarantees the traceability data.

4. The hot forming pipe expanding machine has been widely used in military industry, power station construction, aerospace industry and Marine industry equipment manufacturing industry, and has made a great contribution to customers, steel pipe industry and energy construction.

Medium frequency 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, and has made a great contribution to the national steel pipe industry and energy construction.

Medium frequency pipe expander is applied to the thermal expansion production of seamless steel pipe, straight seam welded pipe, coil pipe and so on.Can expand the variety of steel pipe: all kinds of carbon steel, alloy steel, stainless steel and so on.

Specification of hot expanding steel pipe for medium frequency pipe expanding machine: diameter Φ60 ~ Φ1420mm, wall thickness of 3 ~ 120mm, length of 3 ~ 24m.Can be expanded to make various materials of steel pipe (such as P91-92/T91-92, Q235, Q345, 45#, A106B-C, 12CrMoV).

The medium frequency pipe expander is mainly composed of: base, main cylinder support plate (including main cylinder), movable push plate, front support plate, automatic feeding mechanism, discharging roller table, mold support, intermediate frequency coil adjusting frame (including intermediate frequency heating coil), intermediate frequency power supply, electrical control system, etc
