| Medium frequency heating tube expanding machine technology
The main function of the intermediate frequency heating tube expanding machine is to change the steel pipe into its own inner diameter, the steel pipe through the tube expanding machine will not change the thickness of the steel pipe, only change the length. The working principle of medium frequency heating tube expanding machine is electromagnetic induction technology. The steel pipe is heated and expanded through the mandrel. The electromagnetic induction technology is fast heating, simple operation, stable and reliable, and good stability. The use of hydraulic power, large power stable work. If heating tube expanding machine can be manual or automatic.
If heating tube expanding machine is mainly composed of machine base, main cylinder support plate, movable push plate, front support, IF induction heating coil, tube expanding mold mandrel.
Medium frequency heating tube expanding machine can expand pipe with different inner diameter according to different needs of customers. The company will try its best to meet all needs of customers. There are technical personnel for product installation, debugging and after-sales processing. New and old customers are welcome.
There is a kind of inclined tie tube expanding machine is installed in the bedroom, and the rolling Angle is very large. According to the construction characteristics of this mill, the axis of the roll and the horizontal plane should be parallel, and the two rolls are manipulated to move up or down in parallel at an interval. The roll is pressed down by axial displacement. According to this method of roll adjustment, we can not see the forming process of feed Angle. Usually, the roll of the general inclined pipe binding machine should rotate along the straight line of the axis of the straight roll to form the feed Angle. Oblique tie expanding pipe is oblique tie process, if there is no feed Angle, oblique tie process is impossible to achieve. So the oblique tie expansion pipe must have a feeding Angle, but the need to choose a special Angle to find it. In the process of pipe expansion, the extension change scale is very small, and the wall reduction deformation is mainly transformed into diameter expansion deformation. The general inclined pipe binding machine and the inclined pipe expanding machine are not the same. The wall reduction deformation is mainly transformed into extension deformation, and the surrounding deformation is small, that is, the change of steel pipe diameter is small. Therefore, the key point of the inclined tie pipe expanding machine lies in diameter expansion, which has a very significant characteristics of diameter expansion deformation. Interchanged with thermal expansion pipe production skills, thermal expansion tube selection is a two step propulsion type cone die hole diameter expanding machine set of skills, skills of digital intermediate frequency induction heating, hydraulic skills in one machine, with its reasonable skills, lower energy consumption, low construction investment, compared to a wide range of raw materials and commodities standard adaptability, flexible and simple lower investment yield batch adaptability, Instead of the traditional steel pipe profession drawing type expansion skills. Because it is difficult to deal with the supply of large-caliber steel pipe in the near future, hot expansion steel pipe has become the main commodity source of the lack of large-caliber steel pipe, and the supply situation of large-caliber steel pipe market is serious. With oblique rolling or drawing method to expand the pipe diameter of a steel tube finishing rolling process, in a relatively short time to make the steel tube increased, can produce a special type of seamless pipe, and the cost of low contrast, high production efficiency, is the development trend of the field of rolling pipe around the world.
