1. The debugging method of the Cold Roll Forming Machine, such as the plate running to the right, pad the left corner (feeding frame), or drop the bottom the right (the axis runs off the axis and the axis is flat, and the upper axis falls with the bottom axis.
Find the center of the roll forming machine row and row, then tighten the lock nuts at both ends, and draw a straight line in front of and behind the center of the center wheel. After adjusting the gap between the upper and lower shafts, you can follow the straight line.
2. First, measure the four corners of the front and rear rows of the roll forming machine from the height of the upper end of the shaft of the big frame, and then from row to row, find a line to straighten it, and check whether the lower shaft is in a straight line , and adjust the left and right ends of the lower axis to be horizontal.
Cold bending forming machine can also be called roll forming cold forming, that is, on a row of serial forming mills, the metal plate and the metal strip are connected to bend them in turn, and the flat plate is processed into the required cross-sectional shape.
3. Roll forming has been used for bicycle rims, umbrella skeleton production, etc. The center line of the upper and lower rolls of the roll forming machine should be on the same plane line, subject to the center wheel, the flatness is not more than 1mm, the gap between the upper and lower rolls in each row is equal, and the gap deviation is +0.1mm. Debug with a conventional measuring tool or feeler gauge.
4. In the daily use of the cold forming machine, the problems usually encountered are: distortion, edge waves, longitudinal bending, etc. The problem now is that the force of each force point of the roll is not balanced, and the roll is not in a straight line. Therefore, when debugging, we must seize a central point to consider the problem, that is, the roll should be in a line.
On a straight line, the upper and lower gaps of each group of rolls should be the same, so when there is a problem with the cold roll forming machine, debugging should be carried out around this central idea.
