Description

Technical Field

[0001] The utility model discloses a fixed axial rolling head with an adjustable roller range, belongs to the technical field, and particularly relates to a fixed axial rolling head with an adjustable roller range. 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 texture on the workpiece. The texture created in this way has high dimensional accuracy, surface quality, and material strength, while also achieving 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 special rolling wheels or rolling dies to extrude the workpiece to form patterns or threads. 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 pattern formed by pattern rolling has a high surface finish, improved fatigue strength and tensile strength, while improving production efficiency and reducing unit costs. Therefore, it has been widely used in many industries such as aerospace, automobile manufacturing, fastener production and other fields.

[0004] Disadvantages: High material requirements: The rolling process has specific requirements for the plasticity and hardness of the workpiece material. It is not applicable to materials with too high or too low hardness or poor plasticity. For example, materials with too high a hardness may not be able to form patterns through rolling or cause the roller to wear quickly. Strict control of initial blank size: Before pattern rolling, it is necessary to ensure that the blank size is accurate and consistent. Otherwise, the roller pressure may be too high and the equipment may be damaged due to the size being too large, or the complete thread may not be formed due to the size being too small. Equipment investment and mold cost: Pattern rolling equipment and the corresponding roller molds are usually more expensive than ordinary cutting machines, especially when customizing molds of special specifications, the initial investment cost is higher. Difficulty in process adjustment: Once the rolling parameters are determined, when changing the pattern size or type, it is often necessary to replace the new mold and re-adjust the process parameters, which increases the challenge of production flexibility to a certain extent. Difficulty in quality control: Improper operation or poor equipment condition during the pattern rolling process can easily lead to defects such as inaccurate pattern and thread shape, increased pattern and thread base diameter, and distorted pattern and thread profile. These issues require precise quality control methods to detect and prevent. Unsuitable for complex or non-standard patterns: The lack of readily available roller molds limits the application of pattern and thread rolling processes for unusual pitches, large diameter changes, special shapes, or other non-standard patterns.

[0030] Working principle: Rolling tools usually consist of one or more rollers with shapes corresponding to the desired patterns, and the tooth profiles of these rollers completely match the shape of the pattern to be processed. During the rolling process, the high-speed rotating rollers exert great axial pressure and rolling friction on the surface of the workpiece. Under this strong pressure, the workpiece material (such as steel rods, etc.) undergoes plastic deformation when passing through the rollers, rather than cutting and removing the material, thereby forming a continuous and precise pattern shape on the workpiece surface. Since the pattern formed by rolling is generated by the flow of material, the grain fibers are continuous and there is no obvious cut surface, thereby improving the strength and wear resistance of the grain, while avoiding problems such as burrs and stress concentration generated during cutting. The entire rolling process is efficient and fast, which not only improves production efficiency, but also facilitates chip-free or low-chip processing, which is more environmentally friendly and energy-saving.

[0031] To sum up, the fixed axial rolling head of the utility model adopts a fixed structure with a simple structure; the compression spring 7 structure is added, which has the advantage of floating adjustment; the eccentric shaft 3 is changed to a 5-flat position structure, which expands the adjustment range and is simple to maintain, and the rolling accuracy and range are greatly improved.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
