CONSTRUCTION SPECIFICATIONS

结构描述

§   Roll shafts of Nickel Chromium Molybdenum alloyed steel, induction hardened to  hardness 62-64 HRC and ground, with journals in high dynamic load roller bearings

滚轮轴是镍铬钼合金铸刚，硬度在62-64 HRC，轴颈采用高负荷滚柱轴承

§   Set of modular bending rolls heat treated to hardness 60 HRC to insure long wear resistance

模具热处理硬度达到60HRC，可以确保长时间的加工要求

§   Adjustable slip clutch fit on the upper roll. This device, essential on three driving roll machines, can slow down the rotation speed of the upper roll, compensating for the differing peripheral speeds between the inner and the outer side of the section being curved, in order to insure a smoother drive and accomplish bending radii more accurate than machines without this device.Besides, it protects the drive parts of the machine by stopping the upper roll rotation in the event of accidental overloads

液压驱动：滚轮旋转是由三个独立的带有行星式减速齿轮箱的液压系统控制，液压电机直接连接到每个轴上。液压控制系统能够保证上侧滚轮的低速旋转。

此外，在设备超负荷的情况下，通过停止上侧滚轮的旋转来保护设备的驱动部分依据压力计，通过旋钮来调节圆周速度补偿。
