Rolling Process Procedure
Introduction
The rolling process procedure is an integral part of the metalworking industry, as it is used to create parts of various shapes and sizes. Roll forming is used to reduce the cost of manufacturing, as well as to improve product quality. The rolling process involves a great deal of precision and accuracy, as parts must be rolled to exact specifications. This procedure outlines the necessary steps and equipment needed to successfully roll products.
Preparation
Before any rolling operation begins, it is important to review the drawing and specifications to ensure that the part being rolled is suitable for the process. In addition, the material type, classification and properties should also be reviewed in order to determine the hardness, grain size and rolling conditions.
Experimentation
Before any mass production title processing commences, the rolling process should begin with an experiment. This step is important to determine the rolling parameters that will produce parts of the highest quality. Experimentation is typically done on a small-scale to minimize wastage and maximize production efficiency
Process
Once experimentation has been completed and the best rolling process has been determined, actual production can commence. The rolling process consists of multiple stages, depending on the complexity of the part and desired end result. Generally, the stages are as follows:
1. Pre-bend process
2. Rolling process
3. Profiling rollers
4. Post-bending process
During the pre-bend process, parts are placed in a pre-bend fixture which creates bending information and creates a bend center. The rolling process itself is done using both cold and hot rolling mills. This step is important to accurately create the desired shape and dimensions of the parts. In the profiling rollers stage, each part is shaped by profiling rollers with the desired features. Finally, the post-bending process is used to complete the bends needed for the part.
Inspection
After the part is complete, it should be inspected for accuracy and quality. The inspection should include visual and dimensional checking to ensure the part meets the requirements. This step is important to ensure all parts produced meet criteria.
Conclusion
The rolling process procedure is an important and integral part of the metalworking industry. This procedure outlines the various stages and the necessary equipment required for a successful rolling process. By following these steps, it is possible to create parts of the highest quality.
