The butt welding process of the welded pipe unit includes uncoiling, pinch feeding, straightening, shearing, guiding, butt welding, looper, alignment, etc. The process can be said to be complicated and changeable. Let me tell you about the welded pipe unit first. The first three steps of the welding process:
The specific butt welding process is:
1. After the coil is properly positioned, the left and right taper heads of the uncoiler can be inserted into the steel coil and rotate at the same time, sending the lead to the pinch roller, the upper roller of the pinch roller is pressed down, and the steel coil trolley and magnetic roller can return In situ.
2. In order to allow the spring steel belt to run accurately, the uncoiler can move + 150mm in the axial direction before running. After starting the decoiler, the strip passes through the pinch rollers to the leveler equipped with dust removal device.
3. The straightened spring steel belt is cut with sliding hydraulic shears on the head and tail of the strip (the strip head can be immediately slid into the waste box when the strip is cut, and the cut strip tail can be collected online with an output device In the special collection box on the outside).
