Press paper is one of the failures of CNC winding machine, if there is a problem, we should find the reasons from the following aspects:

A. groove liner forming is not good; shallow indentation, indentation side dark while the other side light, groove liner can not close to the steel plate inner walls of the grooves, slot liners will tilt tapping slot.

Too deep indentation, groove liner elasticity, not close to the steel tank wall, a notch steel sheet.

Molding knife pressure position partial side groove liner in a molding cavity side of high low side side with inserted steel sheet slot paper side will show the notch of the steel sheet. Molding knife across pressure groove in a forming cavity lining, and tilted sideways into a steel groove, both ends of paper will be exposed notch steel sheet.

B. slot liner is too long, long has no support from the bottom part, wire wound into the will to groove liner pulled down by two corner paper exposed the notch of the steel sheet.

C. winding mould: bad die two support angle wear, not care tank liner. Die on the sticker, the corner is not smooth, the assembly line is not smooth.

D. tension setting (winding tension) not too small, offline will be erratic, tankful rate is too high. The last turn is easy to hang in the mold support angle or the assembly line is not in place, corner will cause a line of paper.

E. winding speed is too fast, the tension will be reduced will cause more than the pressure of the paper. (tension assembly disconnection) winding speed accelerate the mold, tank lining around the line tension high, debugging to multi observation and confirmation.

F. indexing speed is too fast, the speed of the winding is too slow, with the not easy to cause the last line on the steel sheet. Indexing is bad (the change in the course of the index), and the last few groups of lines will cause the press.

G. hook angle set too small, tension set too small, the line will be drawn from the line of spring tension, flying fork to the spring line is not tight to make the line easily in the corner of the die did not pull out, easy to cause the last line of paper or around the steel sheet. The 2 fine clip when the mold is separated from the small, spring selection (too small) to fly fork to the spring line can not tense, the same will cause the above situation.
