3 rollers rolling machine

3 rollers rolling machine
This model device adopts the Japanese technology. It can roll plate to cylinder, cone, U-shape and so on. The up roller of this device can do up and down, right and left move. And all the move actions can show by figure.It with the pre-bending capacity.
A. Lifting device of up roller
Using double oil vats to drive directly, the max pressure is 19.5Mpa. The up roller installed roiling bearing, bearing base, piston rod do up and down lifting movement along vertical guides through the bearing. the sides bearing base installed shifting sensor to test move location of the sides of up roller, and show as figure. The material of up roller is 42CrMo and did heat treatment.
B. Drive device of bottom rollers
Drive motor of bottom rollers transmit power to one speed reducer through triangle belt. And the speed reducer roll bottom rollers by outputting bearing gear. The bottom rollers do hydraulic brake by speed reducer.
C. The balance device of up roller
Lifting up roller to highest position, and then the balance beam ends on up roller hold the up roller, so that up roller in balance state. So it is easy to turn over and close turnover bearing base. The position of up roller can monitor by SQ.
D. Base board
Using wielding closed frame base, the function is good about bending resistance, torsion resistance, inertia moment is large, so let people easy to move and install machine.
E. Hydraulic system
a. Hydraulic system composed of gear pump, valve, pipe components and so on.
b. Hydraulic valve comes from Taiwan, the pipe arrangement is succinct, maintain is very easy.
c. System composed of three kinds circuits, press adjust circuit, synchromesh circuit, speed circuit.
d. Synchronization circuit realize rough synchromesh bypass flow of up and by down lift split-flow and throttle valve. Readjusting up and down speed by throttle valve, and tested by shift sensor, synchromesh position accuracy attach 0.20mm of up roller.
