Core pulling rivets, often referred to simply as rivets, are indispensable fasteners designed to connect both metal and non-metal materials with precision and reliability. They are especially valued in scenarios demanding robust strength and seamless flatness post-riveting. Dive into the intricate details of core pulling rivets to discover their remarkable engineering:
1, Structural characteristics
Core pulling rivets consist of two fundamental components: the nail rod, also known as the core rod, and the nail sleeve, referred to as the rivet body. The nail rod is a meticulously crafted metal rod, often adorned with threads or unique shapes. Complementing it, the nail sleeve is a hollow metal cylinder, featuring threads or grooves on its inner wall that perfectly align with the nail rod. Utilizing specialized riveting tools, the nail rod is introduced into the nail sleeve, instigating plastic deformation of the sleeve, thus securing a tight and unyielding connection between two or more components.
2, Working principle
1. Preparation stage: Begin the riveting process by threading the rivet rod through the designated hole, followed by inserting the nail sleeve onto the rivet rod.
2. Riveting stage: Employ riveting tools to grip the tail of the nail rod and apply precise tension. This controlled tension draws the nail rod progressively into the nail sleeve.
3. Deformation stage: As the nail rod is pulled deeper, the nail sleeve compresses, undergoing significant plastic deformation. This process ensures that the threads or grooves on the inner wall of the sleeve engage firmly with the nail rod, establishing a secure bond.
4. Completion stage: Once the nail rod is fully seated within the nail sleeve, the riveting tool releases its hold. The nail sleeve envelops the nail rod snugly, forming a robust and enduring connection.
3, Advantages
1. High connection strength: Through the process of plastic deformation, core pulling rivets provide superior connection strength, ensuring stability and durability.
2. Easy to operate: The use of specialized riveting tools facilitates the riveting process effortlessly, eliminating the need for auxiliary heating or welding tools.
3. Wide applicability: Versatile in nature, core pulling rivets are adept at connecting a multitude of metal and non-metal materials, making them ideal for thin plates, pipes, and diverse components.
4. Beautiful and smooth: Post-riveting, these rivets ensure a surface that is not only smooth and aesthetically pleasing but also devoid of noticeable marks or protrusions.
4, Application Fields
Renowned for their adaptability, core pulling rivets find applications across various sectors including automobile manufacturing, aerospace, construction of curtain walls, electronic equipment, and furniture manufacturing. For instance, in the automotive industry, they are indispensable for assembling body components; in aerospace, they are essential for the riveting of aircraft structures.
In summary, core pulling rivets stand as formidable, user-friendly fasteners whose versatility ensures their critical role across numerous industries. As technology advances and application needs evolve, the performance and array of core pulling rivets are poised for continual innovation and enhancement.
