Automatic Riveter Operating Principles
Setup and Configuration
Machine Setup: Configure the automatic riveter, a specialized tool used for joining materials with rivets, based on the job’s specific requirements, including rivet type, material thickness, and desired joint strength. Understanding what is a riveting machine is essential for this process to ensure the correct configuration.
Rivet Loading: Load rivets into the machine’s hopper or feed system for automatic supply to the riveting head.
Material Placement
Positioning: Position the materials to be riveted, which are often metal or composite, in the machine’s work area manually or using robotic arms and positioning systems.
Clamping: Securely clamp the materials to keep them stationary during riveting.
Rivet Feeding
Automatic Feeding: Use a feeding mechanism, like a vibratory bowl feeder or tape feeder, to deliver individual rivets to the riveting head.
Orientation: Ensure each rivet is correctly oriented for insertion.
Rivet Insertion
Riveting Head: The riveting head, driven by pneumatic or hydraulic power, descends to insert the rivet into pre-drilled holes in the materials.
Pressure Application: Apply a controlled amount of pressure to drive the rivet into materials, adjustable for different sizes and types.
Rivet Deformation
Forming the Joint: Form the rivet head by hammering or squeezing, creating a secure joint. This is a critical step in the function of a riveting machine, ensuring the strength of the connection.
Orbital Forming: Some machines use an orbital path to form the rivet head smoothly and precisely.
Quality Control
Force and Displacement Monitoring: Modern riveting machines are equipped with sensors to monitor the force and displacement during the riveting process, ensuring each rivet is properly installed.
Error Detection: The machine detects and alerts operators to errors, such as misaligned rivets or insufficient pressure.
Cycle Completion
Completion and Ejection: After the rivet is formed, the machine completes the cycle by retracting the riveting head and unclamping the materials. Eject the completed assembly, ready for the next cycle.
Automation and Control
Programmable Logic Controller (PLC): PLCs control the riveting process, allowing precise control and easy adjustments.
User Interface: Operators use a touchscreen panel to set parameters, start/stop cycles, and monitor the process. This interface is a key component of modern riveting machines, enhancing usability and efficiency.
Understanding what is a riveting machine and its components is crucial for operating and maintaining it effectively.
