This SW11SNC 40X3500 NC 3 roller bending roll with our optional device: side bracket, which is conveniently use to long plate during the rolling process.
The main structure is composed of upper roll, down roll and level motion device, support roll device, hydraulic drop end device, main transmissionbalance device, lubricate device, left and right work frame and bottom chassis.
Upper roll device composed of main cylinder, upper bearing pedestal, upper roll, double self-aligning bearing. Upper roll ends fit with double row self-aligning roll bearing to reduce the friction and motor power. The material of upper roll is 42CrMo, after completion of multiple processes such as forging, tempering, quenching, tempering, stress relieving and precision lathe machining (Note: According to the user's different needs, the processing procedure of the roll is different); Strictly ensure that the working roll surface strength is high in the rolling plate, the surface of the roll is free from indentation and can meet the requirements of long-term rolled steel plate. Heat treatment is HB250-280, HRC 40-45.
The material of bottom roll is 42CrMo, heat treatment is HB250-280. It composed of bottom roll, bottom roll bearing pedestal, bottom roll input gear, glide bearing. Bottom bearing adopt SF-2 oil glide bearing.
Level motion motor supply the power, through the strap drive to worm wheel and pole speed reducer. Upper roll level motion drove by worm wheel and pole to finish bending in dissymmetry form.
Composed of sloping block device, support device, support roll bearing pedestal, support lifting device, support roll can adjust up and down. The adjustment depend on plate specification. The material of support is 45# , heat treatment is HB190-220, it made up in helix sharp to protect the surface.
It composed of motor, hard gear speed reducer, output gear, main motor can tuning in two direction and provide bending pitch of strand.
Composed of ram, bearing, tuning cylinder
Composed of Y series motor, gear pump, valves, oil tank, pipe and so on.
Max pressure is 20 Mpa, testing pressure is 24 Mpa, pressure adjusted by overflow valve, system working pressure 0-19 MPa, normal pressure is 15Mpa. The valves is adopted from Taiwan.
Composed of electrical box, operation table, manual button. The power is 380V/50Hz/3PH, it is adopted PLC control system code with longevity easily operate. Whole bending process can read from the indicator setting on the control box.
This machine adopts two sets of digital instrument and displacement sensor formed a reliable digital display and control system.
As a top plate roll bending machine manufacturer, Shenchong always focus on customers' satisfaction.
