Working principle of our 4 roll plate bending machine:
ii. The four working rollers do forge and do material treatment, HB220～260, combination mechanical performance is good, the strength is high, friction endurance is high, so 4 roll plate bending machine suit high load work and have long life.
iii. The work roller end bearing adopt roller bearing, so 4 roll plate bending machine 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 usev. 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 4 roll plate bending 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 strong power part components choose from Suzhou Electrical. So 4 roll plate bending machine has some advantages, long life, trouble-free for a long time, and so on.
ix. The valve block of hydraulic system 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.
