Bending machine accuracy is a key factor in ensuring product size, shape and angles meet design specifications. If the bending accuracy is not high enough, secondary processing may be required to correct dimensional deviations or shape problems. This increases manufacturing costs and production cycle time, and by improving bending accuracy, this additional secondary processing step can be avoided or reduced. High bending accuracy can ensure the production of products that meet quality standards, reduce defective products and scrap rates caused by dimensional deviations, reduce raw material waste and production costs, which is beneficial to the economic benefits and long-term development of the enterprise.Here are some ways to improve the accuracy of your bending machine:
Regular Maintenance and Calibration
In order to ensure the stability and accuracy of the bending machine as well as the bending accuracy, regular maintenance and calibration work is indispensable. Regular maintenance can effectively extend the service life of the bending machine. By cleaning, lubricating, and replacing worn parts, you can reduce wear and tear on mechanical and electronic components and increase equipment durability. At the same time, stability and precision can be maintained. The stability and precision of the bending machine directly affect the quality of the final product. Regular inspection and adjustment of machine tool structure, lubrication system, die and other components can ensure the stability of the bending machine during operation, improve bending accuracy, and avoid product quality differences caused by equipment problems. So how to perform regular maintenance and calibration?
Regular cleaning and lubrication
Keeping the bending machine clean is the basis of maintenance. Accumulated dust and metal shavings may affect the normal operation of mechanical components. Clean the machine surface, guide rails and slides regularly to ensure free movement of all parts. At the same time, check the lubrication system to ensure sufficient lubricant to prevent wear and friction.
Check the machine structure
Carefully check the machine tool structure of the bending machine, including the base, support and body. Make sure there are no cracks or deformations in the machine tool structure, which may affect the stability of the press brake. If problems are found, repair or replace damaged parts promptly.
Inspection and replacement of cutting dies and molds
Dies and molds are key components of the press brake. Regularly check the wear degree of the cutting die and mold. If obvious wear or deformation is found, they should be replaced in time to ensure accuracy and quality during the bending process.
Electrical system inspection
The electrical system of the bending machine also needs regular inspection. Check cables, sensors, switches and control panels to make sure connections are tight and not damaged or shorted. Repair electrical faults promptly to avoid downtime and production interruptions.
Material Selection and Preheating Optimization
Material selection is critical to bending accuracy. Different materials have different mechanical properties and deformation characteristics. When selecting materials, the use and design requirements of the product should be carefully considered, and the appropriate metal type and thickness should be selected to reduce the possibility of deformation.In addition, moderate preheating of the material before bending can reduce the hardness of the material and reduce internal stress, thereby reducing the risk of deformation and improving the accuracy of bending.
First make sure the material you choose is suitable for preheating. Usually, for some metal materials, such as aluminum alloy, stainless steel, etc., the preheating effect is more significant. We can place the material to be processed in the heating equipment according to the bent shape and size. Ensure that the entire cross-section of the material is heated evenly, and also control the preheating time to ensure that the entire material reaches the required temperature. The length of heating time also depends on the type and thickness of the material, as well as the performance of the preheating equipment. Once the material reaches the preheating temperature and is stable, the bending operation can be performed. During the bending process, as the material becomes softer, the required bending shape can be achieved more easily, reducing the risk of internal stress and deformation, thereby improving bending accuracy.
Use Supports and Clamps When Use Bending Machine
Using supports and clamps is an effective method to reduce errors during the bending process and improve the accuracy of bending. This principle involves the use of additional supports and fixtures during the bending process to stabilize and constrain the workpiece, thereby reducing deformation and improving machining accuracy. During the bending process, the use of supports and clamps can provide more fulcrums and stability and prevent unnecessary movement or deformation of the workpiece during the bending process. This helps ensure that the workpiece remains in a fixed position on the bending machine and reduces Uncontrolled changes. In addition, the workpiece may be affected by deflection and deformation during bending, especially during large or complex bending processes. By using supports and clamps, the deflection and deformation of the workpiece can be effectively reduced to ensure that the workpiece is bent after bending. The geometry of the workpiece meets the design requirements. Moreover, the use of supports and fixtures helps to more evenly distribute the stress exerted on the workpiece during the bending process, which helps reduce local deformation and stress concentration, improves the overall stability of the workpiece, and reduces the risk of deformation.
Use High-precision CNC Systems
The CNC system can accurately control each axis of the bending machine, including the movement of the upper and lower molds involved in bending, material feeding, etc. This high-precision motion control ensures the accuracy and consistency of each bending operation.
The CNC system supports multi-axis control, which can control movements in different directions at the same time, making the bending machine more flexible in complex processes. Multi-axis control can achieve more complex bending operations and improve the adaptability and accuracy of the bending machine. Digital programming language (such as G-code) control method can realize detailed adjustment of the bending process through advanced programming technology, allowing operators to accurately define bending path, speed, strength and other parameters. In addition, CNC systems are usually equipped with high-precision sensors for real-time monitoring of various parameters during the bending process, such as material position, bending force, etc. These data can be used to adjust control instructions in a timely manner through the feedback system, making the bending process more accurate. . Generally speaking, the CNC system provides a high degree of control and adjustment capabilities for the bending process through precise motion control, multi-axis control, high-precision sensors and feedback systems, real-time deviation correction and other functions, thereby significantly improving bending accuracy. Also it’s important reaseon why CNC bending machine is so popular.
