The hydraulic system of this device has the following functions: drive oil vat do elevating movement, drive the sides rollers do inclined elevating movement, and drive the turnover oil vat do elevating movement.
With the help of electrical liquid commutate valve to control the down rollers to do elevating movement and the side rollers to do inclined elevating movement. So the working rollers can stop on arbitrary position.
The circuit of turnover oil vat installed one-way throttle valve, it can adjust the speed of executive mechanism.
The hydraulic system design reasonable, work good and allocate high accuracy filter to ensure oil clear. The system pipeline arrange regularity, operator easy, act flexibility. All above these ensure the system no percolation.
The main valves of hydraulic system choose from Taiwan. The pump, filter, motor and seal element choose from native and foreign famous company, so all these have high performance and quality. All components done test, sift, lower the breakdown do our best.
ii. Electrical system
A. Structure
Electrical system display by touch screen and adopts Omron product(includes input and output models. this system has some advantages as the example high ability to prevent interference, long life, prevent shock, work steady and so on.
Sensor adopts high accuracy optical encoder to ensure position accuracy and monitor the position of all rollers. The main components of high voltage part adopt SIEMENS products or some foreign products. So it's has some advantages like as long life, no breakdown time long.
B. The function of control system
a) Automatic control working rollers do synchronization movement
Control the down roller elevating synchronization, the accuracy attached ±0.2mm.
Control two side rollers elevating synchronization, the accuracy attached ±0.2mm
b) Show all actual time data and information of rolling plate.
Two ends absolutely position show at real time of down roller.
Two ends absolutely position show at real time of side rollers.
The ends gradient show at real time of down roller
The ends gradient show at real time of sides rollers
c) The control system provide alarm message, it's help to do some cooperate and maintain.
I. Main characters of the device
i. This machine is four rollers rolling machine controlled by computer. It can pr-bend the ends of plate,
feed plate and don't return. So it pr-bend the ends of plate and roll shape just one time.
ii. The four working rollers do forge and material treatment, HB220260, combination mechanical
performance is good, the strength is high, friction endurance is high, so it suit high load work and have long life.
iii. The work roller end bearing adopt roller bearing, so it has small friction coefficient, decrease reactive
power loss, reduce energy consumption.
iv. Lifting move of bottom roller and sides rollers controlled by computer, automatic leveling, show as
figure at the same time. The synchronized precision ±0.2mm. Plate bending high-precision, easy to use
v. This machine has removable console, the operator more convenient to use, touch-screen display the
location of three work rollers, so that the operator at a glance.
vi. The machine control system using Japan's OMRON intelligent high-speed PLC programmable logic
controller, the system has a fault diagnosis, intelligent judge error, machine tool parts of the monitoring, processing logic, memory, such as power protection; the system with anti-jamming capability Strong, long service life, earthquake, etc. stable.
vii. The sensors of bottom and side rollers has high accuracy ,to ensure position accuracy and monitor
the roller position.
viii. The components choose from SIEMENS of the strong power part. So it has some advantages, long
life, trouble-free for a long time, and so on.
ix. The valve block of hydraulic system are selected from north-Taiwan Seiki products.
This valve block has some advantages, over-charge is big, a small resistance and pressure, hot loss is small, so the function is reliable.
x. Hydraulic pipe joint use of new technologies used in the metallurgical and mining equipment joint
fast, reliable connection to the radial seal to ensure that the equipment in the hydraulic system does not work in oil.
xi. Hydraulic suction system has oil back and oil filter to ensure the system clean , and has air filter to
ensure the fuel tank normal respiration and evaporation of water. there is a two-channel safety protect devices in the system to ensure normal use of equipment
