How to obtain higher accuracy in the practical operation process of Press Brake? (2)
With the steady growth of the industrial and manufacturing base, users' requirements and expectations for their mechanical products are also increasing. For the sheet metal forging and manufacturing industry, CNC Press Brake is a major part of the sheet metal industry. Therefore, as a metal manufacturer, it is necessary for you to learn more about the sheet metal industry or press news.
In the last article, we discussed the knowledge of obtaining higher accuracy in the process of Press Brake processing, so this article, in order to help you improve your brake accuracy, you can try the techniques of the operation steps in the practice of these machines!
1. Use machine preloaders
Machine prepress is a device mounted between the frame of the stamping part and the press brake. It helps eliminate side loads on the pillowers, thereby improving accuracy and consistency. The device is designed to absorb any lateral and vertical movement of the ram.
2. Check the frame geometry
It is important to ensure that the frame geometry is within tolerances. Any misalignment of the frame and stamping parts will cause errors in the forming of parts. A laser alignment system can be used to measure the frame geometry, or a feeler can be used to check the gap between the frame and the stamping to form the part.
3. Check and align the beam bed
The alignment between the beam and the bed should be checked periodically. If the two surfaces are not aligned, the accuracy of the bend will be affected. A laser calibration system or antenna gauge can be used to check the gap. Adjust the height of the bed using the adjusting knob if desired.
4. Check the mold height
Mold height should also be checked regularly to ensure accuracy. If the die height is not within the tolerance range, the accuracy of bending will be affected. The mold height can be checked using antennal gauges or dials.
5. Check the parallelism between Ram and Slide
It is important to make sure that the slider is parallel to the slider. If the slider and the slider are not parallel, there will be an error in bending. A laser alignment system or antenna gauge can be used to check the gap between two surfaces. The adjustment knob can be used to adjust the slider and the slider to achieve parallelism.
6. Check the buffer pressure
The buffer pressure should also be checked to ensure accuracy. If the buffer pressure is too low, it will cause the parts to bend incorrectly. Hydraulic pressure gauges can be used to check buffer pressure.
7. Check the rear gauge
The post-gauge should be checked regularly to ensure accuracy. If the rear gauge is not within the tolerance range, it may cause the part to bend incorrectly. An antennal gauge or dial indicator can be used to check the rear gauge.
8. Check the bending Angle
Bending angles should also be checked to ensure accuracy. A digital protractor can be used to measure the bending Angle and ensure that it is within tolerance.
9. Use precision molds
The use of precision die can help improve the accuracy of parts forming. It is important to ensure that the die is within tolerances to achieve the desired accuracy. If a mold needs to be replaced, use a precision mold.
10. Check ram seal
Ram seals should be checked regularly to ensure accuracy. If the seal is damaged or worn, it can cause the ram to move erratically, which affects accuracy. Replacement seals should be used if necessary.
11. Check the oil pressure of the ram
The oil pressure of the ram should also be checked regularly to ensure accuracy. If the oil pressure is too low, it will lead to irregular movements of the ram, which will affect the accuracy. Hydraulic pressure gauge can be used to check oil pressure.
12. Check the Ram speed
Ram speed should be checked regularly to ensure accuracy. If the speed is too slow, it will cause the parts to bend incorrectly. A tachometer can be used to check the ram speed and ensure that it is within tolerances.
13. Check for vibration
Vibration will affect the precision of parts during forming. It is important to ensure that the brake is not subjected to excessive vibration. If so, it should be treated to prevent errors when the parts are formed.
14. Check the movement
The motion of the punch brake also affects accuracy. The press brake should be checked for any irregularities in its movement, such as jerking or bouncing. If there are any irregularities, the cause should be resolved to prevent errors when forming the part.
15. Check for leaks
Oil leaks can also affect accuracy when forming parts. Any oil spills should be dealt with immediately.
16. Calibrate the press brake
The press brake should be calibrated regularly to ensure accuracy. This process involves adjusting the ram, bed and rear gauge to ensure they are within tolerances. Calibration system can be used to calibrate the press brake .
Through the knowledge in part (1) and the operation steps in this part, with these knowledge, you can apply it to the practical operation of the machine according to the actual situation, and it is possible to achieve the high precision of metal bending.
