the main structure of the equipment is composed of the upper roll device and the press device, the deaf device, the main transmission device, the tipping device, the left and right side frame and the base.
Roller up device and horizontal moving device
the upper roll device is composed of the main oil cylinder, the upper roll bearing seat and the upper roll.
the cylinder body and piston rod are 45# steel forgings. the inner surface of the cylinder is calended-smooth, and the sealing parts of the piston rod are imported. the sealing effect is good and the life is long. To provide the pressure required by the rolling plate, the use of rodless chamber, the main cylinder working pressure is 20Mpa, the rated maximum working pressure is 31.5Mpa. the upper silver is made of 50MN2 and conditioned HB260-300. Aligning bearings are installed on the bearing seats at both ends of the upper roll. the horizontal moving device is powered by the mobile motor, and transmits torque mechanically through the worm gear and screw nut to drive the horizontal movement of the upper roll and realize the prebending of the plate. the material of worm gear and nut is zinc-based alloy ZA27. the material of worm is 40Cr.
Lower roll device
the lower silver device is composed of lower assembly, lower roller bearing seat, lower roller open gear, lower roller sliding bearing, etc. the lower roller is the driving roller, which outputs the gear, open gear and transmission torque to the lower roller through the main drive. the lower silver material is 50MN2, and the quenching treatment is HB260-300: the lower rod wheel material is 45 steel, and the quenching treatment is carried out.
Root breaking device
Roller device is composed of regulating motor, worm gear and worm mechanism, oblique wedge mechanism, roller and so on.
the idler is made of 45# steel, and the tempered HB190-220: the surface hardness of the idler is lower than that of the roller, and the coat surface of the idler is provided with spiral groove, so as to prevent the welding slag, oxide skin and impurities from damaging the working series between the idler and the idler.
