At the National Logistics Development Conference held in Qingdao recently, the person in charge of the Ministry of Railways revealed that in order to meet the needs of modern logistics development, the Ministry of Railways will invest 6 billion yuan by the end of this year to build eight container freight stations in eight major cities across the country. Container transportation business. The west is mainly concentrated in cities such as Chengdu and Lanzhou.
PP103 series cnc Punching Machine 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.
The main machine is a special hydraulic press which is equipped with pressure apparatus and drill drift holding device. There are three drill drifts on the holding device. They are used to install punch and marking apparatus.The body of the machine uses Type C double-plate jointing structure with the advantage of rigid and high power of anti-eccentric load. The main cylinder is fixed on the body by four high strength bolts which is easy to install and convenient for maintenance.
Product Feature:
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.
The Work Table
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. To the movable part, alongside the left-right direction of main engine is called Axis X, and then the movable part is called Axis X rack. Axis X rack is closed to the head of the main engine, on both sides which is installed a supporting plate with universal transmission ball to support the work piece. At the back of the Axis X rack, two rolling guide bushes are installed with a sliding plate on the direction of Axis X. Under the driven by the servo motor and ball screw shaft, the sliding plate can running though the Axis X to realize precise positioning.
The Hydraulic Clams
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. A original location device is installed at the left side of the sliding plate, when the hydraulic cylinder push the locating plate at an angle of 90°, the locating surface is just at the same direction to the Axis Y, and form a rectangle with two clamp surfaces (direction of Axis X) to calibrate the original place of joint plate.
The upper and lower jaws of clamp are spliced which are convenient to replace after abrasion.
The Punching Unit
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 punch is fixed on the rod to tighten the screw, and put the hollowing block into the base of cavity die.
The Manual Lubrication System
Now we equipped the machine with manual lubrication system, previous client need to lubricate the punching and marking dies one by one, now they just need push the handle, it can lubricate the punching and marking dies simultaneously. The operator don`t need reach out to the inside of machine, It`s more convenient and more security.
(Remark: It`s just need lubricate one or two times of one week, depend on the working environment, if you saw the punching or marking rods dry, then lubricate them.)
When package the machines , our workers will fasten every parts by steel wire rope, so as to when the machine on road, it will not move, ensure security of cargo.
