Uses of Riveting Machines

“Riveting Machine” is a broad term that typically refers to the following main types, each with its specific focus:

1. Blind Rivet Guns – For One-Sided Riveting

• Sự miêu tả: Uses pull-through (pop) rivets. Operation is from one side of the workpiece. The mandrel is pulled, causing the rivet body to expand and clamp the materials.
• Primary Uses:
  • Creating joints where access to the back of the workpiece is impossible (e.g., closed sections).
  • Widely used in sheet metal (enclosures, cabinets), automotive, aerospace, Và appliance assembly.
  • Ideal for joining dissimilar materials.

2. Compression Riveters – For High-Quality, High-Strength Riveting

• Sự miêu tả: Uses solid rivets. A massive, static pressure is applied to plastically deform (upset) the rivet tail, forming a second head.
• Primary Uses:
  • Applications requiring exceptional structural strength Và reliability, such as steel bridges, buildings, ships, heavy machinery, Và aircraft fuselages.
  • Produces high-quality, robust joints that withstand high strength and fatigue loads.

3. Orbital Riveters / Spin Forming Machines – For Precision and Special Riveting

• Sự miêu tả: A rotating peen applies pressure and rolls around the center, causing the rivet tail to deform plastically and uniformly.
• Primary Uses:
  • Precision instruments, automotive parts (e.g., brake pads), door/window hardware, jewelry, etc.
  • Suitable for hollow rivets, solid rivets, and peening shafts into housings.
  • The process is smooth and controlled, resulting in excellent surface finish.

4. Impact Riveters – For Traditional Riveting

• Sự miêu tả: Uses a pneumatic or hydraulic impact force to upset the rivet tail in a single blow. This is the most traditional method.
• Primary Uses:
  • Common in construction sites Và maintenance/repair for large metal structures.
  • Often requires two operators (one holding a bucking bar on one side, another operating the rivet hammer on the other).

In summary, a riveting machine is a versatile device for creating permanent metal joints. The choice of machine type depends on the specific requirements for strength, accessibility, and precision.
