CONSTRUCTION SPECIFICATIONS
結構描述
§ 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
滾輪軸是鎳鉻鉬合金鑄剛，硬度在62-64 HRC，軸頸采用高負荷滾柱軸承
§ Set of modular bending rolls heat treated to hardness 60 HRC to insure long wear resistance
模具熱處理硬度達到60HRC，可以確保長時間的加工要求
§ 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
液壓驅動：滾輪旋轉是由三個獨立的帶有行星式減速齒輪箱的液壓系統控制，液壓電機直接連接到每個軸上。液壓控制系統能夠保證上側滾輪的低速旋轉。
此外，在設備超負荷的情況下，通過停止上側滾輪的旋轉來保護設備的驅動部分依據壓力計，通過旋鈕來調節(jié)圓周速度補償。
