          Pipe expanding machine can meet the processing of various diameters  

          The operation of the pipe expander: the washed pipe is fed to the rotating roller on the center line of the diameter expander.  The rotating roller device, combined with a camera system, is used to rotate the pipe weld to 12 points to ensure that the weld enters the groove of the upper sector of the diameter expansion tool during subsequent diameter expansion.  The lifting cone roller lifts the pipe to the center line of the diameter pipe expander and is controlled by a displacement sensor in the lifting hydraulic cylinder.  The clamping car moves forward and is controlled by a metal detector, which detects that the end of the tube is stuck and sends a signal to start the feeding roller of the clamping car. The position is controlled by the encoder.  During driving, a metal detector is arranged at the end of the diameter expansion tube to detect the front end of the tube to measure the position of the tube.  The expansion pipe expander automatically controls the intermediate frequency power supply in the process of expansion pipe production to heat the steel pipe to the required temperature and keep it constant, so as to effectively avoid the scrap of steel pipe and mould caused by the high temperature of the steel pipe, and avoid the increase of thrust of the thermal expansion machine caused by the low temperature of the pull rod or mould.  Combined with the head, automatic calculation of diameter expansion steps.  The clamp can be rotated to avoid damaging the pipe wall.  In the height of the pipe to compensate the diameter deviation of the pipe, and optimize the straightening effect of the diameter pipe expander.  

          For steel pipe thermal expanding machine equipment, mainly for domestic large diameter steel pipe production cannot meet the demand of market and all kinds of steel pipe specification is not complete, meet the needs of small batch more varieties of steel pipe production, can satisfy the different material steel pipe hole enlargement and various non-standard steel tube expanding needs, is currently the main production process of large diameter steel pipe.  It has been widely used in the pipeline oil industry, power plant construction, aerospace industry and Marine industry equipment manufacturing, steel pipe industry and energy construction has made great contributions.  

          The tube expander automatically controls the intermediate frequency power supply in the process of tube expansion, heating the steel pipe to the required temperature and keeping it constant, effectively avoiding the scrap of steel pipe and mould caused by the high temperature of steel pipe, and avoiding the increase of thrust of the thermal expander caused by the low temperature of the pull rod or mould.
