tube mill manufacturer:Stainless steel pipe making machine - introduction of the process flow of butt welding
What is the specific process flow of the welded pipe equipment during the butt welding? The following is a brief introduction to the briefing. Stainless steel pipe machine, tap water pipe machine, stainless steel decorative pipe machine.we are tube mill manufacturer and tube mill supplier,you can know it.
When the welded pipe equipment is further butt welded, after the coil is completely positioned, the left and right tapers of the uncoiler are then inserted into the steel coil and rotated, and the lead is sent to the pinch roller, and the pinch roller is pressed down, the steel roll car With the magnetic roller, you can return to the original position.
In order to ensure that the spring steel strip can be accurately centered, the uncoiler can move axially + 150mm before operation. After the uncoiler is started, the strip enters the straightener with the dust removal device via the pinch roller. The straightened spring steel strip is sheared by a sliding hydraulic shear to the head and tail of the strip.
In order to ensure the verticality of the end of the shear spring steel strip, and at the same time ensure the centering of the strip centerline and the unit operating center line during welding, the front and rear of the hydraulic cross shear are cut. After the tail of the first spring steel strip and the head of the next coil are cut, the head and tail of the front and back coils are sent to the flash butt welder for centering, stitching and flash welding.
After the strip head and the tail are welded, the weld bead is finished and punched, punched and bent, etc. After the welding and processing are completed, the strip is fed into the front loop by the roller at a high speed. The upper strip is supported by a plurality of swinging door rollers of the looper, and the lower strip is supported by rollers on the steel rail.
