This roll forming machine unit is usually formed by de-coiler, leveling device, punching hole device and computer control system, etc. The main improve steps including the following 4 sides, details are as follows:

 

1. Add the length measurement device and saw, the saw start to work when the output length reached the set length, automatically cut the profile structure materials.

2. Add one set of hydraulic Punch-hole device. Punching 4 holes at one time. The saw cut the middle part of the profile. Then, we get the closed two holes of the head and end.

3. Then add a set of punch middle-hole device. During the roll forming process, punch the middle holes according to user’s demand. The max quantity is 16 middle-holes.

4. If need to punch the double holes in the middle of profile material by the steel keel roll forming machine, we can change the 4 side-holes punch molds to the 2 side-holes punch molds, revise the program of punching side-hole. Make the side-hole punch device punch the double holes in the middle part. Meantime, the distance of the middle-hole is set by user. This roll forming machine can mostly punch 8 groups double-holes.

 

The Debugging method of the steel keel roll forming machine

1. Adjust platen deviation. If the platen runs deviate to the right side, pad the left corner (de-coiler), or put the right corner lower to flat.

2. Find the center of the first row and the last row, then lock the nuts of the two sides. Pull a straight line at the front and behind of the middle center of the middle wheel, after adjust the distance of the above and lower shafts, you can adjust the other shafts along the straight line.

3. At first, measure the height of machine frame to bottom shaft, then measure the four corners of the closed two rows height. Ensure that these heights are in the same level, then, pull a straight line from the first row to the last row. Ensure the height of all the rows keep the same.


This steek keel roll forming machine also have the advantages such as easy operate, easy maintenance, easy adjust, easy change the molds, etc.
