Key points for attention in cold roll forming

2023-08-31
1. Material selection
Before cold bending, it is necessary to select suitable materials. Usually, iron, steel, and their alloys are common choices. However, different materials have different physical properties, so the most suitable material should be selected according to the needs. For example, for thin plate materials with smaller radii that require bending, materials with a certain degree of elasticity should be selected, rather than materials that are prone to fracture.
2. Preparation before processing
It is necessary to carry out sufficient preparation work before cold bending forming. This includes cleaning, anti-corrosion treatment, polishing, and other operations. Before cleaning the material, it is necessary to remove all debris and dirt to ensure a smooth and even surface, which will help improve the quality of the molding. Anti corrosion treatment is the process of protecting materials from moisture and chemical corrosion. If there are rough or rusty spots on the surface of the material, it will greatly reduce the quality of the molding. Therefore, adhering to the cleanliness and anti-corrosion of materials is crucial.
3. Mold planning
The planning of molds is an important part of cold bending forming. Because different materials and shapes require different types of molds to complete. The planning of molds should take into account necessary process requirements, while preventing waste of resources and reducing costs, while improving processing power. For example, some materials may require pre tightening to enhance the bending effect and prevent surface defects.
4. Selection of Forming Machinery
The selection of forming machinery is also crucial, as it should select the most suitable forming machinery according to the needs. This usually depends on the type and shape of material required for molding. The selection of forming machinery should be based on the requirements of the processing target, selecting an appropriate cutting width to ensure the quality and accuracy of the forming. At the same time, it is necessary to ensure that the mechanical equipment and maintenance are suitable, and regular maintenance and repair should be carried out to ensure its normal operation.
5. Processing process
When performing cold bending forming, the cold bending manufacturer needs to ensure that the material is always sufficiently hard during the process to prevent defects or deformation. In addition, it is necessary to prevent excessive force from being applied during the processing process to prevent cracks or fractures on the surface of the material. When conducting twists and turns, it is necessary to pay attention to the processing temperature and speed to ensure the quality and accuracy of the molding. During the molding process, if any problems are found, they should be promptly addressed to ensure that the quality of the processed products meets the requirements.
