Manhart 如何根据工件的材料特性来调整扭轴数控折弯机的加工参数？

Adjusting the machining parameters of the torsion axis CNC bending machine based on the material properties of the workpiece is a key step in ensuring machining accuracy and workpiece quality. The following are specific methods for adjusting processing parameters based on the material properties of the workpiece:
###1、 Understand the material properties of the workpiece
Firstly, it is necessary to have a deep understanding of the physical properties (such as elastic modulus, tensile strength, yield strength, etc.) and mechanical properties (such as plastic deformation ability, toughness, hardness, etc.) of the workpiece material to be processed. These performance parameters will directly affect the deformation behavior and processing difficulty of the workpiece during the bending process.
###2、 Select appropriate processing parameters
According to the performance of the workpiece material, selecting appropriate processing parameters mainly includes the following aspects:
1. * * Bending force * *:
-Harder materials require greater bending force to overcome their internal stress and achieve bending deformation.
-Materials with poor toughness require appropriate reduction of bending force to prevent cracking during the bending process
2. * * Bending angle * *:
-Determine the required bending angle based on the workpiece design drawings and product requirements.
-For certain materials, it may be necessary to fine tune the bending angle to compensate for their rebound or deformation during the bending process.
3. * * Bending speed * *:
-Harder materials can be appropriately accelerated in bending speed to improve production efficiency.
-But for materials with poor toughness or easy deformation, the bending speed should be appropriately slowed down to ensure machining accuracy and workpiece quality.
4. * * Mold selection * *:
-Select the appropriate mold based on the hardness and shape of the workpiece material.
-The accuracy and wear of the mold can also affect the machining accuracy and surface quality of the workpiece.
5. * * Pressure distribution * *:
-Reasonable pressure distribution during the bending process can ensure that the workpiece is subjected to uniform force during bending, avoiding local deformation or cracking.
-Adjust the pressure distribution device according to the performance of the workpiece material to adapt to the processing requirements of different materials.
###3、 Conduct trial processing and adjustment
1. * * Trial processing * *:
-Before formal processing, conduct trial processing to verify the rationality and effectiveness of the selected processing parameters.
-Observe the deformation, surface quality, and whether there are cracks or fractures during the bending process of the workpiece.
2. * * Parameter Adjustment * *:
-According to the trial processing results, make necessary adjustments to the processing parameters.
-If the workpiece experiences excessive deformation or cracks, the bending force can be appropriately reduced or the bending speed can be slowed down; If the workpiece has insufficient bending or poor surface quality, you can try increasing the bending force or adjusting the mold, etc.
###4、 Precautions
1. * * Safe operation * *:
-When adjusting processing parameters and conducting trial processing, it is essential to follow safety operating procedures to ensure the safety of personnel and equipment.
2. * * Equipment Maintenance * *:
-Regularly maintain and upkeep the torsion axis CNC bending machine, check the wear and deformation of each component, and replace damaged parts in a timely manner.
3. * * Recording and Feedback * *:
-Record the parameter settings and processing results for each processing for subsequent analysis and improvement.
-Timely feedback on problems and difficulties encountered during the machining process in order to obtain technical support and assistance.
In summary, adjusting the machining parameters of a twisted axis CNC bending machine based on the material properties of the workpiece is a complex and meticulous process that requires comprehensive consideration of multiple factors. Through reasonable parameter settings and precise trial machining and adjustment, the machining accuracy and quality of the workpiece can be ensured to meet the design requirements.
