Project Overview Duct Insulation Attaching Mechanism

Project Overview and Targets Goals: 20% speed improvement 95% fastening success rate Accommodates 1 and 2 inch Gripnails or Weld Pins Accommodates various shape, size sheet metal Manufacture machine

Initial Concepts External and internal research done by team Designed three possible machines Number of heads Gripnail vs. Weld Pin Safety features Flat surface or Grid surface Could also redesign and improve existing machine

Initial Concepts (Cont.)

Research and Experimentation Fastening Strength Gripnail impact test Gripnail and Weld Pin extraction test Finite Element Analysis Frame Design Modal Analysis

Final Design

Linear Motion and Hopper Hopper placed top of each actuator 3 moveable heads, 1 stationary head Move along single ACME screw Supported by upper and lower rail

Frame and Impact Surface I-beam for the center column Square tubing for frame structure FEA analysis showed greater frame strength with gusset Raised harden impact surface

Actuators Secondary actuator loads Gripnail Magnet holds Gripnail Lasers

Control Panel 8 electronic air solenoids 4 for impact actuator 4 for loading actuator PLC unit for machine control Moisture separator

Recommendations and Next Steps Proof of Concept Phase Order Components Refine Bill of Materials Development Impact Mechanics and Feeding System Actuator Movement Frame Structure
