Difference between riveting and pressing riveting

Riveting and crimping are two common metal connection techniques. Let's learn from Dongguan Hongrui Hardware Technology Co., Ltd~

Mainly used to fix thin plates or parts together. Although both methods are used to connect metal parts, there are significant differences in their operation methods and applicable scenarios.

Flip rivet

Riveting is a method of connecting by flipping a part of a metal nail or rivet over to form a head. During the riveting process, specialized tools are usually used to insert rivets into pre made holes, and then one end of the rivet is deformed by compression to form an enlarged head, thus achieving a fixed connection of two or more pieces of metal.

characteristic

High strength: The connection point formed by flipping the rivet has high shear resistance and tensile strength because one end of the rivet is flipped and enlarged.

Reliability: The head formed by riveting is not easy to fall off, and the connection is more stable and reliable.

Wide applicability: Riveting can be used to connect various materials, including but not limited to metal sheets, plastic parts, etc.

Operational complexity: Compared to riveting, flipping riveting is more complex and requires specialized tools and certain operational skills.

Press riveting

Riveting is the process of using a press or specialized tool to press threaded rivets (also known as rivet bolts, rivet screws, etc.) into pre made holes, and fixing the rivets in the holes through plastic deformation to achieve the purpose of connection. Riveting is commonly used in applications that require rapid disassembly or repeated assembly.

characteristic

Easy installation: The riveting operation is relatively simple and fast, and does not require special tools to complete the installation.

Reusability: Due to the threaded nature of the rivet bolt, it can be repeatedly disassembled without affecting the connection strength.

Applicability: Suitable for occasions that require frequent disassembly and assembly, such as electronic device casings, chassis, etc.

Load bearing capacity: The connection points formed by riveting mainly rely on thread engagement, so their load bearing capacity may not be as good as that of riveting.

Difference Summary

Operation method: Riveting is to deform the rivet into a head by squeezing, while riveting is to achieve connection by pressing in a threaded rivet.

Connection strength: Due to the formation of a larger head, the shear resistance and tensile strength of flipping rivets are usually better than those of pressing rivets.

Application scenarios: Riveting is suitable for applications that require high connection strength, while crimping is more suitable for applications that require frequent disassembly and assembly.

Tool requirements: Riveting requires the use of specialized tools for operation, while riveting is relatively simple and can be completed using ordinary tools.

The choice between riveting or pressing depends mainly on specific application requirements, the stress situation of the connecting parts, and whether repeated disassembly and assembly are needed. In practical operation, technicians will choose appropriate methods based on the actual situation to ensure the stability and reliability of the connection.
