Automatic rolling tube machine works

Automatic rolling machine works: capillary wall after piercing is very thick, very uneven surface, with a clear spiral ribs, the need for further processing. Rolling is a major step on the wall reprocessing. Automatic rolling machine rolling equipment is widely used in the past. The use of longitudinal rolling method, oval hole in the rolling of the capillary, the deformation process is completed in the annular space formed hole and the plug. Its rolling process is:

After piercing capillary rolled along stripes down the automatic rolling machine and bottom work rolls and rolls down next time. In order to remove the oxide scale and play a role in the need to lubricate the inner capillary throw salt industry. Then with the help of Pusher under the capillary into the roll, rolling two to three times the upper roll and the automatic rolling machine. In order to make uniform thickness, reducing ovality outer circle, before rolling the first two requiring inversion pipe 90 degrees. Then sprinkle with salt and replace the plug, the plug diameter than the second track is generally the first plug diameter 1 ~ 2mm. Finally, lowering the rolling motion rolling machine rolling machine rolling through. Through steel pipe rolling mill after rolling, automatically returns to the automatic rolling machine reception, turn the stripes are sent to the machine frame.
