Description

Technical Field

[0001] The utility model discloses a closed ring, belongs to the technical field of rolling tools, and particularly relates to a rolling tool and an automatic closed ring. Background Art

[0002] Rolling technology belongs to the fields of mechanical manufacturing, metal forming, and metal part surface hardening. It is a non-cutting process that uses tools to deform metal materials to create patterns on the workpiece. The patterns created in this way have high dimensional accuracy, surface quality, and material strength, while also offering high production efficiency.

[0003] Rolling technology originated in the early 20th century. With the development of metal plastic deformation theory and the progress of practical applications, it has gradually become an efficient and energy-saving precision forming process. The technical background mainly includes the following aspects: Material science and mechanics foundation: Rolling processing relies on the plastic deformation ability of metal materials, that is, under a certain pressure, metal materials can undergo permanent shape changes without destroying their internal continuity. This requires that the materials used have good plasticity and strain hardening properties. Advances in mechanical manufacturing technology: With the improvement of mold design and manufacturing accuracy, as well as the research and development of high-efficiency and high-precision rolling equipment, rolling technology has been realized and gradually improved. This technology uses a special knurling wheel or rolling die to extrude the workpiece to form a pattern. Energy-saving and environmental protection needs: Compared with traditional cutting methods, rolling processing belongs to the category of chipless processing, which not only reduces the generation of cutting waste, but also reduces energy consumption, which meets the requirements of modern industrial production for green manufacturing and sustainable development. Demand for improving quality and reducing costs: The patterns formed by rolling have a high surface finish, improved fatigue strength and tensile strength, while improving production efficiency and reducing unit costs. Therefore, they have been widely used in many industries such as aerospace, automobile manufacturing, and fastener production.

[0004] Disadvantages: High Material Requirements: The rolling process places specific demands on the workpiece's plasticity and hardness. It is not suitable for materials with excessively high or low hardness or poor plasticity. For example, materials with excessively high hardness may not form patterns through rolling or may cause rapid wear of the rollers. Strict Initial Blank Size Control: Before pattern rolling, the blank dimensions must be precise and consistent. Otherwise, excessively large blanks may cause excessive roller pressure and equipment damage, while undersized blanks may prevent the formation of complete threads. Equipment Investment and Tooling Costs: Pattern rolling equipment and the accompanying roller dies are generally more expensive than conventional cutting machines, especially when customizing dies for specific specifications. The initial investment is high. Process Adjustment is Difficult: Once rolling parameters are determined, changes in pattern size or type often require replacement of dies and re-adjustment of process parameters, which increases the challenge of production flexibility. Quality Control Difficulty: Improper operation or poor equipment condition during the pattern rolling process can easily lead to defects such as inaccurate pattern shape, increased pattern base diameter, and distorted pattern teeth. These issues require sophisticated quality control to detect and prevent. Not suitable for complex or non-standard patterns: For unconventional pitch, large diameter change, special shape or other non-standard patterns, the application of pattern rolling process will be limited due to the lack of ready-made roller molds.

[0005] During the rolling process of a traditional axial rolling head, the rolling head can open automatically but cannot close automatically, and an external force needs to be applied to close the rolling head. Utility Model Content
