APPLACATION:
Special CNC machine for punching and marking of steel plates in the field of steel tower industry. It is also used to punch and mark of steel plates of other industries.
Features:
1. The machine-frame is made by C-type plate welding, with good rigidity and big handling space. The machine sets three die-stations (two punching, one marking), automatic switching die-stations. Clamping system can be adapted to different workpiece, with reference block, and workpiece supported by rolling-ball working table. X & Y axis action controlled by servo motor and ball-screw driving and PLC, control the position of punching, so as to make the whole machining process automatically. Operator input the workpiece program, it can be used repeatedly
2. Adopt CNC technology, servo motor infeeding, with high efficiency, stable workpiece precision.
3. Important functional components adopt modular assembly, easy to repair it.
4. Achieve punching and marking on the one plate.
5. Easy programming, can read CAD drawing and also can use the program generated by lofting software. It can ready TEKLA lofting software files, such as NC1 format.
6. With self-diagnosis failures function.
7. X, Y axis are driven by servo motor + ball screw + linear guide, the precision is better.
8. POWER: Three phase four wire systems
Detail:
CNC feeding worktable can be divided into fixed part and movable part. The fixed part is set on the ground which is linked with main unit. To the fixed part, alongside the front-back direction of main unit is called Axis Y, and then the fixed part is called Axis Y rack. The movable part is installed on the Axis Y rack through the guide bush which is rolling in straight line, under the driven by the servo motor and ball screw shaft, the movable part is running though the Axis Y to realize precise positioning.
There are two hydraulic clamps on the sliding plate, their location can be moved alongside the Axis X so as to adjust different work piece. While in adjustment, loose the screw and press plate, move the clamp by hand to the adequate place, fasten the screw and press plate again. In the vertical direction, the clamp is in the condition of floating. To the joint plate with slight unevenness, they may be arched during punching, and then the clamp will be moved accordingly to avoid the breakage of clamp.
There are one service position of marking and two positions of punching on the machine. While in marking, put the required characters into the character box and fill the vacancy with blank characters, then screw the bolts to tight, insert the character box to the fixed groove at the top of the piston rod. The punching mould shall be selected in accordance with the aperture and plate thickness.
The hydraulic pressure system is mainly composed of oil tank, punching & marking regulator, pressure system block and drill system block. Each part is connected with steel pipe or hose, and oil tanks are driven under the control of electrical CNC system to realize calibration, clamping, pressing, punching, drilling and marking etc.
