3-roll asymmetrical plate rolling machine

ⅠStructural characteristics

The machine adopts the 3-roller asymmetrical structure with the upper roller as the main drive and the lower roller making vertical movement so as to clamp the plate materials tight. The main drive comes from the engagement between the gear of the lower roller and the gear of the upper roller. The side roller makes elevating movements and has the function of preliminary bending and rolling. The machine is characterized with compact structure and convenient operation and maintenance.

Technical parameters

Ⅱ main technical data:

ⅢMain structure and working principle :

This machine is composed of part of the work, the main motor, transmission of the side roller, lower rollers, and overturned balance device.
   1. The working part is composed of the upper roller, lower rollers and side rollers. and its working principle: The bottom roll lifting vertical, top and bottom roll clamp sheet metal and move side roll to bending by plastic deformation, the top roll (active roller) spin, and then passed through the gears by bottom roll. the roller and the sheet metal friction between the sheet metal along the length of the drive the direction of movement. when the plate pass the deformation zone, its elements to be uniform along its length bending. So, the machine works by the movement and rotation of the axis

The top and the bottom rolls are all active roll, top roll force passed through a pair of meshing gears to the bottom rolls, which overcome the friction moment of sliding bearings, solving the often slippery sheet rolling problem, to improve the conditions of sub-coil.
   2. Main motor unit consists of a main motor through a pair of gear reducer to the top and bottom rolls to achieve coil speed. Used between the motor and reducer coupling with a brake wheel, brake means for the hydraulic brake.
   3. side roll transmission
   In order to ensure the accuracy of work rolling machine, the side rolls’ ends must be ensured synchronized. The machine adopt mechanical transmission, by the motor through reducer, and the worm gear to receive a corresponding female screw thread revolutions, and through the screw, corresponding to the speed side roll down movement. Side roll stroke limit position switch controlled by the stroke switch.

4 the bottom roll device
   Under the roller bearing in the composite sliding bearing, the composite bearing supported on iron on the ramp and lower roller bearing and the side through the complex dynamic between the rack and moves vertically with the lower roller vertical movement with manual or electric, transmission Route to: handle a trip through the two nut, screw (screw attached oblique iron), and then pass through the inclined railway to the next roller to roll under the corresponding displacement.
   5. balance equipment
   Balance device uses tension bolts for structural adjustment. When the overturned aircraft overturned, top roll is appropriate in the horizontal position . Balance device adjusted by a fixed nut tight. Strictly prohibit loosening the nut, rotate tensional bolt body.
   6. stroke control device
Side roll limit position controlled by stroke switch control, with manual control of the bottom roll stroke.
