                                3 Roller Hydraulic Plate Rolling Machine  

       More than 20years rolling machinery making experience

     The biggest plate rolling machine manufacture in China

Precision of the superior products

Unique crooked craft , the high-accuracy tip is curved in advance, the crooked angle after not having in succession, the crooked course is digital control.
Man-machine dialogue controls the high-efficient intelligence of interfaces to operate
Peculiar crooked craft software, the interactive window, the automatic compensation of the crooked course, operate singly, high-efficient and safe and convenient!

Abundant crooked form
Have rolls of form to make O type, U type, many sections of R ,etc. different forms.

Choice of many models According to the use or users' enquiry, count and show the model economily, TC numerical control model chooses.

3.The Main Structure:

This equipment should be composed of main structure, hydraulic system , electricity control system and cone device.

3-1. The main structure

The main structure is composed of upper roller , down rollers and level motion device support rolls device , tuning device , balance device, lubricate device , left and right work frame and bottom plate.

1) The upper roller

upper rolls device composed of main cylinder, upper bearing pedestal, upper rolls, double self-aligning bearing .two cylinders provide the pressure for upper roll bending , main cylinder working pressure is 20 Mpa ,max pressure of upper roll multiply 0.8 times to compensate for pre-bending. Upper roll two ends fit with double self-aligning bearing to reduce the friction and motor power.

The material of upper roll is 42CrMo , heat treatment is HB220-280.  HRC 45-55
