Stainless steel sheets are a widely used metal material across various industries, known for their corrosion resistance, aesthetic appeal, and durability. Bending stainless steel sheets is a common metal forming process that allows the creation of components and products in various shapes and sizes. However, the bending of stainless steel sheets comes with its challenges and requires attention to several key aspects:
1.Choose Appropriate Bending Dies:
Selecting suitable bending dies is crucial when working with stainless steel sheets. Due to the high hardness of stainless steel, there is an increased risk of wear and scratches on the dies. Therefore, it is essential to opt for high-quality dies with smooth surfaces, high hardness, and excellent wear resistance. Regular inspection and maintenance of the dies are necessary. Additionally, the selection of the upper die angle and lower die slot width should be based on the thickness of the stainless steel sheet and the desired bending radius. This ensures bending accuracy and quality.
2.Control Bending Intensity and Angle:
It is crucial to control the bending intensity and angle when working with stainless steel sheets, as they exhibit significant springback. Both excessive and insufficient bending intensity can adversely affect bending accuracy and quality. Therefore, based on parameters such as the thickness, width, and length of the stainless steel sheet, it is essential to pre-calculate reasonable bending intensity and angles. Adjustments should be made during actual operations. In general, to mitigate the springback effect, it is advisable to slightly increase the actual required angle and then make corrections after the bending process is complete.
3.Avoid Scratching and Discoloration:
The surface of stainless steel sheets is susceptible to scratching or abrasion from dies or other objects, impacting its aesthetic appearance. Additionally, bending at high temperatures can lead to oxidation and discoloration of the stainless steel surface. Therefore, it is essential to clean and protect the stainless steel sheet both before and after the bending process. Minimize contact with dies or other objects during operations. Furthermore, when cooling at elevated temperatures, attention should be given to controlling the cooling rate and duration to prevent undesirable effects on the material.
4.Pay Attention to Safety Measures:
During the bending process of stainless steel sheets, there is a generation of temperature rise and stress that may result in material deformation or fracture, posing potential harm to operators. Therefore, it is crucial to conduct safety checks and implement preventive measures before commencing operations. Operators should wear appropriate protective gear to ensure their safety.
