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!
Built-in Pressure cylinder: Pressure cylinder setting on the lathe bed can solve the piston rod damage problem that the work-piece'roll scale accumulate in the process of bending due to cylinder rod exposure.
Strengthened cone bending package: There is a cone small-mouth slowing device set on the top and bottom working roller's bearing block. The electrical system can control the working roller's inclinayion and maintain the top roller's balance. This machine can meets the requirement of small diameter, large cone angle bending.
Hydraulic advance release pressure system: Through the special design of hydraulic system and working pressure checking, the machine can be unload on the condition of high pressure to avoid the problem of "water hammer", work-piece bouncing compact on piping.
Clean human-machine interface: Working pressure of hydraulic and each cylinder, motor working state, displacement of sensor will be displayed on the screen in form of instrumentation control. The power failure of each valve, prompting of each soft and hard limitation, overload alarming, oil temperature alarming, prompting of cooling also will be displayed on the screen.
This machine used to coil plate into different sharps such as cylindrical form, conic form and arc, it adopted Japan hydraulic technical.Top roll can does vertical and level motion, up and down, parallel translation is display. This machine include pre-bending function.
The Main Structure:
This equipment should be composed of main structure, hydraulic system , electricity control system and cone device.
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.
The upper rollerupper 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
Down roll and level motion device.The material of down roll is 42CrMo , heat treatment is HB220-280.. it composed of down of roll, down roll bearing pedestal, down roll input gear, down roll, glide bearing. Down bearing adopt SF-
oil glide bearing.Level motion motor supply the power, through the strap drive to CWU worm wheel and pole speed reducer. Upper roll level motion drove by worm wheel and pole to finish bending in dissymmetry form.
Support deviceComposed of sloping block device, support device, support rolls bearing pedestal, support lifting device, support rolls can adjust up and down. The adjustment depend on plate speciation. The material of support is 45# , heat treatment is HB220-280, it made up in helix sharp to protect the surface.
Main drive deviceIt composed of motor, hard gear speed reducer, output gear, main motor can tuning in two direction and provide bending pitch of strand.
Overturn deviceComposed of ram, bearing, tuning cylinder
Balance deviceComposed of balance compact, screw
Hydraulic systemComposed 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 adopted from Taiwan.
Electricity systemComposed of electrical box, operation table , manual button . the power is 380V50HZ adopted PLC control system code with longevity easily operate. Whole bending process can read from the indicator setting on the control box.
Digital display system
This machine adopts two sets of digital instrument and displacement sensor formed a reliable digital display and control system.
