Welding roller frame industry standard technical requirements? Active wheel should speed DC motor or AC motor through a gearbox drive wide. ? Active wheel peripheral speed welding process should meet the requirements of three rainbow roller frame within 6 ~ 60m / h variable speed range;? Rate fluctuation different welding process is divided into Class A (≤ ± 5%) and B level (≤ ± 10%), self-aligning roller frame roller frame by initiative, driven roller frame and control system components. Active roller frame roller rotating AC inverter motor drive inverter, with a wide speed range, smooth rotation is good, low-speed characteristics and other characteristics hard, driven roller frame roller gearless wheel frame by frame through the workpiece active wheel drive passive rotation. ZT wheel frame can be within a certain range automatically adjusted according to the size of the workpiece diameter wheel set roller section swing angle, without manual adjustment, if on the height of the main post, driven rollers make appropriate adjustments can be cone into the constitution, points the role of the assembly and welding roller frame segment diameter ranging rotator wheel frame _ _ Third Wuhan Heavy Rainbow by Rainbow Heavy Industries Co., Ltd., Wuhan three.
