1, the machine is a microcomputer-controlled four-roller plate rolling machine, with plate end pre-bending function, steel plate feeding, without turning head to complete the plate end pre-bending and rolled into shape.
2、The machine four work rolls 42CrMo forging round, after forging, tempering treatment, HB241 ~ 286, surface quenching, hardness HRC52-58, comprehensive mechanical properties, high strength, wear resistance, suitable for high load work, long service life.
3、The machine adopts rolling bearing at the end of the working roller, with small friction coefficient, which reduces the reactive power loss and saves energy.
4、The lower and side rollers are controlled by computer, with automatic leveling, digital display, synchronous accuracy ±0.2mm, high precision and easy operation.
5、The machine's lower and side rollers can be tilted at one end, and can be raised and lowered at the same time in the tilted state, which is conducive to the rolling of conical workpieces.
6、The machine is equipped with movable operating table, which is more convenient for the operator to use, and the touch screen shows the position of the three working rollers, so that the operator can understand at a glance.
7、The machine control system adopts Siemens intelligent high-speed PLC programmable controller, which has the protection functions of fault diagnosis, intelligent discrimination of operation error, monitoring of each part of the machine tool, logic processing, power-off memory, etc. The system has the advantages of strong anti-interference ability, long service life, anti-vibration and stable operation.
8、The sensor of the lower and side rollers lifting and lowering displacement of the machine adopts high precision sensor to ensure the position accuracy and realize the position monitoring of each roll.
9、The main electrical components of the strong electric part are all made of Siemens products, which have the characteristics of long service life and long trouble-free time.
10、The main valves in the hydraulic system are made of Yuzhi Oil Research products. The valve set is cast flow channel, with large overflow, small resistance, small pressure loss and small heat generation, which makes the machine performance more reliable.
11、The hydraulic pipeline joints are all adopt the new technology metallurgical mining with quick-fit joints, the joints have reliable radial seal to ensure that the equipment in the work of the hydraulic system does not leak oil.
12、The hydraulic system has suction and return oil filter to ensure the cleanliness of the system, air filter to ensure the normal breathing of the oil tank and water evaporation, the system has a double-channel safety protection device to ensure the safety of the use of equipment.
13、Turning bearing body (inverted head) is equipped with dumping cylinder, the inverted head can be tipped and stood up, which is convenient for the workpiece to take material, the turning and resetting of the turning bearing body is equipped with interlocking device, after the turning bearing body is turned over, other actions are in the standby state, and only after the turning bearing body is reset can the action be resumed, which plays a safety protection role.
14、The upper roller is equipped with a balancing device at the end, the balancing device is to balance the upper roller while the tilting bearing body is turning over, when the inverted head is turned over and discharged, the upper roller is in a balanced state by the balancing mechanism, so that it is convenient to take out the barrel-shaped workpiece.
15、The machine adopts the whole base, strong rigidity, good lifting, easy to install, the frame and base are welded structure, and annealing aging treatment, eliminate internal stress, improve the precision of the coiling machine. The whole structure of the machine is composed of building blocks, beautiful shape, more convenient maintenance.
