The maintenance of the welded tube equipment of the stainless steel ERW tube making machine is very important. Proper maintenance can greatly extend the life of the welded pipe equipment, increase its safety and stability, and ensure the quality of the welded pipe.

The maintenance principles of ERW tube making machine are as follows:

1. The horizontal frame of the ERW tube making machine is a two-kun type side-out knuck-type bracket. When the knurl needs to be replaced, loosen the fixing bolts of the outer support, pull out the outer support, and replace the knurl on the side, which is simple and convenient. The pressing and adjustment of the frame is carried out separately on both sides, and the adjustment is flexible, convenient and high-precision.

2. Likun can be adjusted in the horizontal direction at the same time or separately in the machine base, and can also be adjusted in the vertical direction separately, which is more convenient. The rolling bearing is used for rolling bearings.

3. The feeding rack of ERW tube making machine adopts a rotatable parallel four-link cantilever double-reel mechanism, which can wind up the belt during the working process of the unit, which can reduce the preparation time and enable the unit to continue without a looper device. Production.

4. The center line of the main shafts of the first two weld seam grinders and the rolling center line are at an angle of +/-45 and can be adjusted to polish the weld seam from two staggered directions. Grinding the weld at an angle of 90 degrees with the rolling centerline makes the polishing effect better.

5. The electrical configuration of the stainless steel ERW tube making machine and welding machine unit adopts frequency conversion speed regulation.
