W12 Four-roller Rolling machine, plate rolling machine, hydraulic bending machine, 4-roller rolling machine,
W11 Three-roller rolling machine,steel plate rolling machine
This belongs to four roller plate rolling machine,up roller is fixed and it is the main drive,hydraulic motor driven by variable speed drive gear up and down roller belt drive, to provide torque for the roll sheet; under the roller moves vertically through the hydraulic pressure acting on the piston of hydraulic cylinder obtained in order to clamp plate for hydraulic transmission; the down roll of the sides with side roller and cylinder driven by oil.The machine advantage of end plate bending(pre-bending) and rolling can be conducted on the same machine
Structure and main parts:
This equipment composed of work frame , upper roll device , main drive device, down roll device, side roll device, overturn device ,hydraulic system(parts) , electricity system(parts), and lubricate device .
Work frame of rebar thread rolling machine
Body from the base, a fixed side frame and the tip side of the rack, and each part is steel welded structure. Were fixed with bolts on both sides of the rack in the base and sides of the rack will be used to connect beams connected to rigidity good. Both sides of the rack up roller and side rollers with movement of rail, fixed on the side of the rack with roller bearing for half of the closed frame structure, has overturned side rack shelf support devices. Coil force in the process of both sides of the rack by the bear from the base not only supports the weight of the machine to ensure the accuracy of the role of equipment, but also enables a torque between the drive and chassis balance, and will join into one machine. In the now traditional large-scale four-roller bending machine body and the main gear is separate from the base installation.
Upper roll device
The up roller gear drive from the main for turning, the ends of the SP-1 bearing support, drive-side through the flat key, off the main drive gear and connect the device to transfer torque, tip-side with the protection of Steel . The material of the up roller is 42CrMo, heat hardening is HB220-300.
main drive device:
By the Hydraulic motor, three speed reduction gear, transmission torque to the up roller. This device include motors and speed reduction gear box. Power supply is according to customer's requirement
Down roller device:
Down roller supports under the bearing, the bearing housings on both sides of the rack mounted inside the track, the bottom of the piston and cylinder connected. Bearing in the liquid under pressure can rise and fall along the rail, according to the size of the thrust rod, steel plate under the roller clamping force required by the hydraulic system pressure control valve be adjusted. Addition of the down lower rollers can roll adjustment, improve the accuracy of product under the same material as the roll quality alloy steel 45#, heat treatment hardening is HB220-300
Side roller device:
Side of the roller bearing in the radial bearing pedestal, bearing on both sides of the rack mounted inside the track, the bottom of the piston and oil cylinder connected. Bearing in the liquid under pressure, can be tilted up and down along the rail, the size of the piston rod of the thrust force according to the needs of steel plate by the hydraulic system pressure control valve be adjusted. The side roll quality alloy steel, heat treatment hardening is HB220-280.
Overturn device through the oil cylinder , hinges torn off and driving overturned on a roller bearing aircraft overturned in order to remove products.
