Use of the machine

The folded sheet metal bending machine has high productivity and high working accuracy, using different shapes of the upper and lower mould, can be bent into various shapes artifacts, stroke at a time can be to a bending forming of sheet metal, after a lot of bending can obtain more complex in the shape of the workpiece, when equipped with the corresponding equipment, can also make a punch.

Product shape and structure

1. UG (finite element) analysis method, computer aided optimization design, beautiful appearance.

2. The machine adopts steel plate welding structure, with sufficient strength and stiffness, hydraulic transmission to ensure that the work will not be caused by the thickness of the plate or the lower die "V" shaped groove improper selection of serious overload accidents, in addition to the machine has the characteristics of smooth work, convenient operation, low noise, safety and reliability.

3. The cylinder is equipped with a mechanical block to ensure the repeated positioning accuracy of the sliding block to the bottom dead point, so as to ensure the consistency of the bending Angle during mass production.

4. Adopt integral tempering to eliminate internal stress and process the frame by CNC floor boring and milling machine to ensure the mounting surface accuracy of oil cylinder, guide rail and worktable.

5. The whole frame should be rust removed and sprayed with anti-rust paint.


Work slider structure

1. The machine adopts hydraulic electric control, the slide stroke can be adjusted arbitrarily, and has the action specifications of point, semi-automatic, automatic, etc., the use of the point standard can be convenient for mold test and adjustment.

2. Up moving bending machine design, double cylinders work at the same time, the operation is balanced, convenient and safe (servo motor adjusts the stroke of Y-axis cylinder)

3. The lower dead point has the function of keeping the calendering time to ensure the precision of the workpiece.

4. Under the relevant national standard conditions, the accuracy of bending Angle can reach ±45´. (citing standard JB/T22572-2011)

5. With the function of slow descent control, the operator can better control the workpiece.


The hydraulic system

1. Hydraulic system (German Bosch Rexroth) can realize the sliding block fast descending, slow descending, working speed bending, fast return and up, down the process of the sliding block emergency stop and other actions.

2. The oil pump adopts (SUNNY) gear pump in the United States, which can withstand high pressure and low noise.

3. The oil pipeline adopts the combination of German clamp sleeve joint and galvanized cold-drawn pipe, which eliminates the need to replace the sealing ring to overcome the oil leakage phenomenon.

4. The sealing ring is made by Japan NOK Company, which has good sealing performance, reliable operation and long life.

5. The machine can work continuously under rated load. The hydraulic system has no leakage and is continuously stable with high accuracy.


Electric control system

1. Electrical components and materials meet international standards, safe and reliable, long service life, strong anti-interference ability.

2. With removable foot switch operation.

3. The electronic control components are of high quality and famous brand products.

4. The machine adopts AC 380V three-phase four-wire system power supply, and the control loop is AC 220V voltage.

5. The main circuit of the motor has the protection of short circuit, overload and phase loss.

6. The operation button is installed on the button table of the machine tool, and the electric switch and indicator light are installed in the special electrical control box.

7. The stop button of the oil pump is also used as the main button of the machine tool. When the oil pump stops working, the whole machine tool stops working.

8. The machine tool is equipped with corresponding inching control button and emergency stop button.

Slider synchronization control

The synchronization of the slide stroke of the bending machine adopts the mechanical and hydraulic synchronization mechanism, which is simple in structure, stable and reliable, and has the synchronization precision required by the machine. Generally, it does not need frequent maintenance to maintain long-term use.

After the keep-off

1. Adjustment of rear stopper is driven by servo motor.

2. Rear stopper screw adopts precision ball screw positioning and high precision linear guide support.

3.H type synchronous belt synchronous wheel drive, high transmission accuracy, low noise.

4. Adopt the upper and lower adjustable fine tuning finger block with higher precision, which ensures the positioning accuracy more.

E200P system

1. LCD HD display.

2. Control the rear stopper shaft (X) and stopper shaft (Y).

3. Automatic fast movement and low speed positioning.

4. Independent manual movement of X/Y axis.

5. Bend counting function.

6. Set the scale factor freely.

7. Multi - step programming, automatic operation of the program, continuous positioning.

8. Memory the position, program and parameters of the stopper and stopper after power failure. 

9. Automatic retreat function, avoid the interference between the rear stopper and the workpiece.

10. Unidirectional positioning function, eliminate screw transmission clearance.

11. M/Inch conversion function.

12. Hardware diagnostic function.

13.100 procedures, 25 worksteps.
