| Power saving mode of IF tube expander
Our company HAS DEVELOPED a new energy SAVING IF tube expanding machine, which saves 10%-35% ELECTRICITY compared with ordinary tube expanding machine, and has achieved success. Structure of IF tube expanding machine: tube expanding machine base, hydraulic structure, IF coil, core head, push plate, wheel bracket, electric reducer, hydraulic tightening structure, raw material pair, hydraulic roller and tightening guide structure.
The medium frequency tube expanding machine has a diameter of 60mm-1420mm, a wall thickness of 3mm-120mm and a length of 3-24mm. It can expand steel pipes of various materials.
Technical parameters of steel tube flaring machine: flaring diameter: 60-1900mm, flaring wall thickness: 3-100mm (segmented design and manufacturing equipment). Flaring steel pipe length: 3-12m. The tube flaring length is 1-1.5 times of the tube diameter.
The structure of the intermediate frequency expanding machine is divided into: rack device, main cylinder and the plate, steel tube feeding, steel pipe rack, steel tube center device, steel tube flaring and exit the clamping device, the hydraulic control system, electric control system (work station), intermediate frequency power supply heating equipment, heating coil to adjust frame, induction heating coil back and forth, flaring die, cooling water system, etc.
1, the automatic control of intermediate frequency power supply at the time of expanding production will steel tube heated to the required temperature and constant, especially in the thermal expansion of high alloy steel pipe, more can reflect the system adapt to thermoplastic deformation temperature region superiority of narrow, effectively avoid the human factors caused by the alloy steel pipe burnt (high temperature) to produce the quality of steel pipe and the mold scrapped, At the same time, it avoids the tension rod or die fracture caused by the increase of thrust of thermal expansion unit due to low temperature. Ensure the smooth operation of the hot pipe expansion unit, reject the unstable factors.
2, intermediate frequency expanding machine automatic constant temperature system of intermediate frequency power supply with constant temperature heating one, thus ensuring thermal expansion pipe heating is always in a state of constant temperature, compared with the manual operation of steel pipe heating, energy-saving health, simplify the procedures, reduce the labor costs, can achieve a operators at the same time monitoring the ten most normal production expansion tube expanding unit, And through pressure, speed, temperature programming overload protection. The unsteady factors due to the high pressure of the tube expanding unit in the pipe expanding production.
3, each set of two temperature measuring points automatic temperature control, according to the preset heating temperature of different grades of steel pipe, select the heating temperature of the steel pipe to be expanded and keep constant, and can be real-time display and record, can print and save the heating temperature parameters of the real-time curve and historical curve. At the same time, the relevant information such as temperature, time, working pressure, speed and so on will be automatically stored to guarantee the traceability of data.
