During user use BYFO series HVAC lockformer, we in actual need to change different thicknesses of sheet for HVAC duct fabrication, and sometime user find that the forming shape will be not very perfect even not well formed but machine running well. So how should we do in this situation?
It is because of the original gap between the upper and down rollers is not anymore fit to next thickness you use. Now we need to adjust this gap following below method.
First, we remove the top metal covers. BYFOCNC pittsburgh lock former, S lockformer and snap lock former usually have two types of screws in roller plate. Two different types of screws as one group screws, We name both NO.1 and NO.2 like below pictures we marked.
The screw we name NO.1 screw, each one of this screw is used for adjusting gap in this position. The screw we name NO.2 screw is used for fixing or tightening plate position. If you use thicker sheet to make HVAC duct, you have to make the gap bigger a little, then you have to screw out each NO.1 screws a little and at the same time tighten the No.2 screws. After you adjust all screws, test with new sheet again.
This is the way we adjust the gap in BYFO Lockformer. We can not sure the other brands of lock forming machine adjustment are the same method. Thank you!
