Mild steel equal angle straightening machine
Working mode of machine: Angle steel enters into in the middle of straightening rollers by the rotating of straightening roller and Pinch device.
The bending parts of angle steel produce the deformation, and is straightened back and forth by changing its curvature when angle steel passes these rollers.
Pressing down value for top roller to angle steel directly influences the straightening accuracy and times of angle steel.
Gantry type of structure with high rigidity and strength
Multi-roller cold straightening
Integrated 4 active rollers and 5 units idle rollers by two interconnected bearing seats
Straightening roll can move with the bottom roller to prevent from distortion and torsion of angle steel.
4 active rollers and 5 groups of idle rollers are the integral structure by two interconnected bearing seats, they can take out from the bearing seat holes of machine frame.
Pressing down advice with 10 sets of worm & worm gear as well as screw & screw rod pairs.
Two bearing seats of each roller and pressing down device is combined, which is operated by hand wheel, and Pressing down value is displayed by the dial.
The active roller uses bevel wheel gear reducer motor, which is driven directly by gear coupler with large torsion force and high efficiency.
The active roller can be inched.
The active roller can work continuously as well as starting on loading so that the back and forth and adjusting of roller can be done according to the actual situation.
Lubrication on both sides of bearing for active and idle rollers is done by manual grease pump at regular time.
