Detail
The high frequency welded pipe production line usually has the problem of thin-walled pipe fold line. The pipe surface fold line refers to the thin and shallow dents that exist on the surface of the formed tube blank in the circumferential direction. The thicker and deeper ones are called "slubs". Tubes and ultra-thin-walled tubes; sometimes the broken line can be seen but not felt, and some can be seen or touched, with a slight touch. The common feature is the appearance of surrounding tube blanks.
The fundamental reason is that the tube blank is relatively soft and has wrinkles. The following measures can be taken to adjust the high frequency welded pipe production line:
(1) Give up the storage, let the unit drag the tube billet away, and then stop the machine to connect the belt. Although the efficiency is lower, the quality can be guaranteed.
(2) Strengthen flat roll rolling in sections to eliminate broken lines. That is, first use the W-shaped roll and the second rough forming roll to roll the edge of the shaped tube with a larger rolling force, so that the edge does not have a broken line feel; then appropriately increase the third to the fifth rough forming flat roll Rolling force to eliminate the broken line at the bottom of the tube.
(3) Pay special attention to the balance of the force on both sides of the upper flat roll, and appropriately increase the rolling force.
(4) Wrap the finished tube with a thin cloth, hold it by hand and move it in a spiral manner to confirm the effect of eliminating the broken line; then add a certain amount of rolling force in a targeted manner.
The above is to propose adjustment solutions for the thin-walled pipe surface folding line of the high frequency welded pipe production line. I hope it will be helpful to you.
