Hydraulic three-roller bending machine, used for medium and heavy-duty bending machine. The frame is solid welded. All rollers are matched with high-quality heavy-duty ball bearings. Since the planetary gears are directly mounted on the rollers, the hydraulic rollers are driven independently The motor and planetary gearbox are driven to ensure that the friction of the bending roller is minimized and the rotation is uniform, and the transmission of force will not cause power loss. Simultaneous use of torsion bars and hydraulic devices to ensure maximum machining accuracy and production flexibility.
Heavy and sturdy cast-iron construction:
rolls of high pressure steel
comfortable eccentric clamp system and easy operation
conical round
wire insert grooves
hardened up gear for high durability
asymmetrical 3-roller system
top roller can tilt out with eccentric closure
High efficiency of thick plate bending work：
Reduced size, easy to transport on medium and large machines
If the two bottom rollers move horizontally, it also means a lower working height, which requires a smaller foundation pit and less anchoring load (in the smallest model, you don't need a foundation).
The W11S machine can achieve the best pre-bending on each required diameter. The possibility of reducing the center distance between the lower rollers enables better pre-bending when bending small diameter and thickness tubes.
Another important future for the W11S machine is the operating system of the top forming roll. In fact, the top forming roll can be
In the same way, a thick cone can also be obtained by bending the sheet multiple times
For some 3-roller and 4-roller cone machines, it is necessary to tilt the top roller to allow removal of the produced tube. On W11S machines, this is unnecessary, so it is easier to remove the finished tube.
