Medium frequency pipe bender in the process of operation is the first consideration of the pipe bender process, the use of equipment or tools for production work, on how to use and material preparation, stable environment, quality assurance and other aspects of the work steps to describe the production of material and in line with the law of smooth production of the operation process.

Before starting the medium frequency pipe bender, first check the main machine, auxiliary machine, water pump, oil pump, air compressor, etc. of the pipe bender should be in good condition.Check the power supply, the components are in good condition, in the standby state, start the cooling water flow system back and forth, adjust the water pressure to the pressure required by the elbow, start the oil pump, check the oil system, put the oil control valve in the closed position, other valves in the elbow position.Start the intermediate frequency power supply, after the input of the intermediate frequency power supply, the heating temperature of the steel pipe to the low temperature required by the elbow, slowly adjust the amount of oil, start to push the tube, push the tube at the beginning, should pay close attention to the advance speed and heating temperature, power rise and fall, push speed increase and decrease should be with the temperature, to ensure that the heating I let you lose not over temperature.Thick wall alloy tubes for diathermy diathermy method can test, can generally according to the following method: using low power, prolong diathermy, bend is not greater than 800 ℃, the outer wall temperature steel pipe inner surface temperature of 600 ℃ or so slowly push pipe bend, in the process of the ejector sleeve, ejector pin while ascending power, strict supervision and bend temperature and pushing speed, rated parameters to bend.If the pipe diameter is greater than 300mm and the wall thickness is greater than 30mm, the first processing can not be successful, the outer wall temperature should be strictly controlled. When the outer wall temperature reaches 950℃, turn off the intermediate frequency power supply. When the outer wall temperature falls to 750 ℃, start the power supply again immediately and push the bending pipe slowly, such as the intermediate frequency power supply of the pipe wall, the inner wall temperature can not reach 600℃ or so.The method can be used repeatedly. When the temperature behind the secondary outer wall is less than 600℃ in the production process, the machine should be shut down to study the reasons and make countermeasures before bending the pipe.In the process of pipe bending, the operation of water pump, oil pump and air compressor should be checked frequently. If found, it should be dealt with in time.

Through the above operation process, customers in the production process after completion, should be timely cut off the power, do a good job of cleaning and smooth work.
