Manhart 调整扭轴折弯机参数时,如何考虑材料的硬度与弹性模量?

When adjusting the parameters of the bending machine on the torsion axis, considering the hardness and elastic modulus of the material is an important step to ensure the quality and efficiency of the bending process. Here are the detailed steps on how to adjust the parameters of the dynamic bending machine on the torsion shaft based on the hardness and elastic modulus of the material:
1、 Understand the hardness and elastic modulus of materials
1. Hardness: Material hardness is the ability of a material to resist external forces pressing into its surface, usually used to indicate the degree of softness or hardness of the material. Harder materials are more difficult to deform during bending and require greater bending force.
2. Elastic modulus: The elastic modulus is the ratio of stress to strain during the elastic deformation stage of a material, reflecting its ability to resist elastic deformation. Materials with high elastic modulus undergo less deformation during bending and require more precise parameter adjustment.
2、 Parameter adjustment method
1. Adjustment of bending force:
-Hardness: For materials with high hardness, due to their strong resistance to deformation, it is necessary to increase the bending force to ensure that the workpiece can achieve the required bending angle. When adjusting the pressure control device of the bending machine, the bending force should be appropriately increased according to the hardness of the material.
-Elastic modulus: Materials with high elastic modulus undergo less deformation during bending, therefore requiring more precise control of bending force. When adjusting the bending force, it should be ensured that the magnitude of the bending force can accurately control the deformation of the workpiece, avoiding excessive or insufficient deformation.
2. Adjustment of bending speed:
-Hardness: For harder materials, although the bending speed can be appropriately accelerated to improve production efficiency, excessive bending speed may cause cracks or fractures in the workpiece during the bending process. Therefore, when adjusting the bending speed, the bending speed should be appropriately reduced according to the hardness of the material to ensure the bending quality of the workpiece.
-Elastic modulus: Materials with high elastic modulus have less deformation during bending, so a more stable bending speed is required to control the deformation of the workpiece. When adjusting the bending speed, the stability of the bending speed should be ensured to avoid excessive speed fluctuations that may cause uneven deformation of the workpiece.
3. Selection and adjustment of molds:
-Hardness: Materials of different hardness have varying degrees of wear on molds. Harder materials will cause greater wear on the mold during the bending process. Therefore, when choosing a mold, the appropriate mold material and specifications should be selected based on the hardness of the material to ensure the service life and bending quality of the mold.
-Elastic modulus: The angle and position of the mold have a significant impact on the bending effect of the workpiece. When adjusting the mold, the angle and position of the mold should be adjusted according to the elastic modulus of the material to ensure that the workpiece can obtain uniform deformation and accurate bending angle during the bending process.
3、 Precautions
When adjusting parameters, the principles of low pressure, small bending angle, and shallow depth should be followed, and the size of the parameters should be gradually increased to ensure processing quality and machine performance.
2. During the adjustment process, carefully observe the operation of the machine and changes in the quality of the workpiece, and be prepared to deal with possible abnormal situations at any time.
3. Regularly maintain and upkeep the equipment, check the wear and tear of the molds and the operating status of each component to ensure that the equipment is in good working condition.
By following the above steps and precautions, the parameters of the twisting axis bending machine can be accurately adjusted based on the hardness and elastic modulus of the material, thereby achieving high-quality bending processing results.
