Core pulling rivets, frequently referred to simply as rivets, are indispensable fasteners known for their robust connection capabilities. These rivets are ideal for joining both metal and non-metal materials, particularly in scenarios demanding exceptional strength and a smooth, flat finish post-riveting. Below, we delve into the specifics of core pulling rivets:
1, Structural Characteristics
Core pulling rivets are ingeniously designed with two primary components: the nail rod, or core rod, and the nail sleeve, also known as the rivet body. The nail rod is a threaded or specially-shaped metallic shaft, while the nail sleeve is a hollow metallic cylinder featuring inner threads or grooves that perfectly complement the nail rod. During use, a specialized riveting tool expertly pulls the nail rod into the nail sleeve, inducing plastic deformation in the nail sleeve, thereby securely fastening two or more parts together.
2, Working Principle
1. Preparation Stage: Begin by threading the rivet rod of the core pulling rivet through the designated hole, followed by inserting the nail sleeve onto the rivet rod.
2. Riveting Stage: Utilize riveting tools to grip the tail end of the nail rod and apply tension. This tension gradually draws the nail rod into the nail sleeve.
3. Deformation Stage: As the nail rod continues to be drawn in, the nail sleeve undergoes compression and plastic deformation. This process ensures that the threads or grooves on the inner wall of the sleeve engage snugly with the nail rod.
4. Completion Stage: Once the nail rod is entirely pulled into the nail sleeve, the riveting tool releases the tension, leaving the sleeve firmly enveloped around the nail rod, completing a steadfast connection.
3, Advantages
1. High Connection Strength: The plastic deformation mechanism of core pulling rivets results in an exceptionally strong bond.
2. Effortless Operation: With the aid of specialized riveting tools, the riveting process is straightforward, eliminating the need for additional heating or welding equipment.
3. Versatile Applicability: Core pulling rivets are versatile, suitable for connecting a wide range of metals and non-metals, making them especially effective for thin plates, pipes, and other components.
4. Sleek and Smooth Finish: Post-riveting, the component surfaces remain neat and polished, devoid of any conspicuous marks or protrusions.
4, Application Fields
Core pulling rivets find widespread application across numerous industries, including automotive manufacturing, aerospace, building curtain walls, and electronic equipment. In automotive manufacturing, for instance, pop rivets are instrumental in joining body components, while in aerospace, they are crucial for aircraft structure riveting.
In conclusion, core pulling rivets are a potent, user-friendly fastening solution with a significant role across various sectors. As technology advances and application needs evolve, the performance and variety of core pulling rivets will continue to advance, offering even more enhanced solutions.
