| The method of making elbow by pushing elbow machine
First cut the good steel pipes for thermal system, head or bend machine is core mandrel, mandrel has fine coarsens, elbow bend machine in the production process is a process with a curved hole diameter, the back support, under the steel pipe section through the mandrel, behind the mandrel is fixed, through hydraulic mechanical transmission, steel pipe section slowly walked down the mandrel, mandrel induction coil outside,The tube is heated through the induction coil and then an elbow is machined.
The pushed elbow should be reshaped in this hot state. If the elbow is not handled properly, it will be twisted and reshaped through the reshaping mold.Shaping mold is the pressure machine with a mold, two semi-circular arc, up and down each one.After shaping the outer diameter of the elbow to the size of the finished product, the composition and technical parameters of the elbow machine
Elbow machine mainly: hydraulic pump station, operation table, motor control cabinet, intermediate frequency power supply, compensation capacitor, water cable, intermediate frequency coil adjustment frame, reactor
The following are the specifications, models and technical parameters of several common elbow machines
Type 1, 6 '3 ", "12" 8 "16" - 24 "to 30" 20-36 "30" - "to 48" 32 "- 56"
