10. a kind of steel pipe spinning temperature automatic control method, which is characterized in that by using described in any one of claim 1 to 9
Steel pipe spinning temperature automatic control equipment realize, comprise the following steps:
Step 1, steel pipe (700) to be processed is clamped and installed on buldging lathe (100) by chuck (131)；
Step 2, buldging lathe (100) are operated, main shaft (130) drives steel pipe (700) quickly to rotate；
Step 3, pass through temperature control system (600) human-computer interaction interface, opening gas circuit, sparking of igniting the torch, in line flame heating
Torch (210) and the igniting of single hole flame heating blowpipe (220) burning combustible gas are heated, while temperature sensor (410) starts to measure
Steel pipe (700) temperature；
Step 4, heating device (200) heating steel pipe (700), temperature control system (600) are cut-off and are lighted a fire by control gas circuit
Torch sparking, realizes the closed-loop control of temperature of steel pipe；
Step 5, after processed steel pipe (700) has reached assigned temperature, the slide unit (120) of buldging lathe (100) feeds fortune
Dynamic, spinning wheel (121) is contacted with steel pipe (700) completes closing in operation；
Step 6, steel pipe (700) closing in completion of processing, buldging lathe (100) parking, control gas circuit are closed, and time processing mistake is completed
Journey.
