HYDRAULIC SYSTEM,MECHANICAL SYSTEM,CNC SYSTEM,SYNCHRO CONTROL SYSTEM, SERVO MOTOR POWER: 0.55 KW.
1. THE STRUCTURE OF THE MACHINE
Welded steel plate, the frame consists of right and left wall boards, working table, oil box, groove steel and etc. The stress of the parts have been eliminated by vibration. The machine enjoys high accuracy and high strength and good rigidity.
2. HYDRAULIC SYSTEM
It is a complete electrolyte servo synchro CNC controlled press brake.
3. MECHANICAL SYSTEM
(1)It adopts the electolyte synchro control system whose acuracy is very high. There are two light rulers installed at the two ends of the slide, this can make the slide movement be parallel to the working table.
(2) It adopts the working table compensation structure in which way the accuracy can be improved.
(3)The positioning accuracy of the CNC servo motor of the back gauge is very high.
4. CNC SYSTEM
(1) The DA65W computer is originally imported from Holand Delem Co. which is specially used for press brakes.
(2) The DA65W CNC control system is very advanced technology. The system can work steadily and reliablely .
(3) The CNC system can calculate the working time and quantities of press brake actions automatically. In this way it saves the labour and time to calculate the material consumption
(4) This CNC system can store 25 press brake procedures, and you can make multiple steps per procedure.When you process different parts, you just need to find out the programmed procedures inside the computer and then the computer can work well on every steps as per the programing
(5) The CNC system can give alarm signals on incorrect operations and this can avoid the mistakes in operation
(6) The CNC system can control below datas automatically: pressure discharge time, pressure keeping time,press brake pressure, press brake angle, the opening height of slide and etc
5. SYNCHRO CONTROL SYSTEM
Two light rulers (Y1-Y2) have been installed at the two sides of the machine to measure the exact distances between the slide two ends and the working table. The rulers are connected with the working table. In this way the wallboard deformation will not affect the slide positioning accuracy.The position data will be delivered to the CNC system and then it can check out the servo valve control signal (S2-S2)
6. THE DEVIATION RESISTANCE ABILITY OF THE MACHINE
The elctrolyte servo system of this machine is an inner closing ring control system.It can check out the synchro discrepancies of the slide by the movement of the light ruler.And the elctrolyte servo valve can correct the slide discrepancies. This can make the slide always be parallel to the working table
7.THE ACCURACY OF THE MACHINE
X-axle, the repeated positioning accuracy is: +-0.1mm;
Y-axle, the repeated positioning accuracy is :+-0.01mm
Y-axle, the parallel accuracy is:+-0.02MM
8. ADVANCED TECHNOLOGY AND PROCEDURES
(1) CYLINDER: no. 45# steel treated, the inside holes fine machined and rolled and ground
(2)VALVE RODS: NO.45# steel treated,nickell and phosphorous coated on outside.
(3)MAIN COMPONENTS:
Oil pumps are from Shanghai Plant
Main hydraulic components are from Germany BOSCH
The main electric parts are from French Schneider.
