Control system and working state of pipe expanding machine

Control system and working state of pipe expanding machine  

In the process of production and expansion, the pipe expander controls the intermediate frequency power supply to keep the heating temperature constant to the required temperature, which effectively avoids the abandonment of the steel tube and the mould caused by the high temperature of the steel tube due to human factors, and avoids the phenomenon of the mould fracture in the pushing process of the pipe expander with too low temperature.  Compared with manual operation, the steel pipe is heated, which saves energy, simplifies the operation procedure and reduces the labor cost.  The hydraulic pipe expander is equipped with two temperature measurement and automatic temperature control, so that the pipe expander can set the heating temperature according to different steel tubes, select the heating temperature of the steel tubes and keep it constant, and can display and record in real time, and can save the heating temperature parameters.  

Model 3 "-- 12" 8 "-- 24" 16 "-- 30" 20 "-- 36" 30 "-- 48"  

Working pressure of pipe expanding machine 25 MPa Working speed of pipe expanding machine 0-1000mm /min Fast retreat speed 1500-2000mm /min Inner diameter of hydraulic cylinder 180*2 250mm*2 360mm*2 320mm*4 360mm*4 stroke of hydraulic cylinder 6500mm  6500mm 6500mm 6500mm 6500mm hydraulic cylinder thrust 60T*2 120T*2 250T*2 200T*2 250T*4 motor power 22.5KW 46KW 48.5KW 75KW 100KW required medium frequency power 250KWA  400kwa 600kwa 800kwa 1000kwa  

The simple components of the pipe expander include: base, main cylinder, movable support plate, front support plate, automatic feeding, feeding roller table, mold bracket, intermediate frequency coil and intermediate frequency heating coil, intermediate frequency power supply, electrical control system and so on.  

The pipe expanding machine and the pipe expanding machine can expand the diameter of the steel pipe from 60mm-1420mm, the wall thickness of 3mm-120mm, the length of the steel pipe above 3-24mm. The pipe expanding machine of our company can produce these expanded steel pipe models.  

The advantages of pipe expanding machine and diameter expanding machine are: energy saving, simple operation, high production efficiency, reduce the cost of workers, and one person can operate more than one pipe expanding machine.  

The pipe expanding machine is also called the diameter expanding machine. The pipe expanding machine and the pipe expanding machine can enlarge the steel pipe to the pipe diameter that the customer needs.  In simple terms, the small pipe diameter is changed into a large pipe diameter through the pipe expanding machine and die.  Select the mandrel by selecting the model required by the customer.
