Feature:

  hydraulic 3 roller bending machine with long service

This machine belongs to hydraulic 3-roller plate rolling machine. The top roller makes up-down movement and horizontal movement, the up-down movement is drove by the force of hydraulic oil in hydraulic cylinder on the piston rod, it is fluid drive and the two lower rollers make rotation movement and it provide the torque for rolling plate though the gear mesh of reducer. There are support rollers under the two lower rollers and the support roller can be adjusted; top roller is of drum shape, which can improve the straightness of products, and it is proper for various kinds of extra long section shape tanker. The pre-bending is achieved by adjusting the top roller and makes it in asymmetrical position as opposed to lower roller. Rolling of working piece is achieved by lower roller movement driven by a reducer. Due to the level of lower roller will not change, it is easy to feed the plate and operate.

1)      High-precision end of the pre-bending, set the length of the straight edge freely; direct pressure on the pre-roll bending, high-precision can be completed in advance of the end of the bend.

2)      NC control, high productivity products rolling process parameters NC, simple and substantial increase in efficiency.
