We are a four man senior design team at the University of Idaho working on a bolster rivet press for Buck knives.

Project Goal[edit]

Effectively design and fabricate a bolster rivet press for Buck Knives that will increase operator efficiency and safety while maintaining a high level of product quality. The machine will allow the compression of all three rivets in a single action and have the capability to accommodate multiple knife fixtures

Background Information[edit]

Buck Knives currently produces a common knife model known as the 110. Last year, Buck Knives supported a senior design project where the team was tasked with creating a machine that inserts pins into three locations in the knife. This year we are re-creating a bolster rivet press to press these pins to hold the knife together. The machine that Buck Knives is currently using to press the pins does not meet there needs or standards. The new machine must meet all of Buck Knives needs and standards stated in the Design Specifications section

Design Specifications[edit]

  • Operator should position the knife, press 'start', and then be free to do other work-cell tasks
  • Machine should press all three rivets w/o need of operator assistance
  • Machine should signal when rivets are pressed and knife is ready for retrieval
  • material adjacent to each of the three rivets should not be visible damaged
  • Knife should open/close normally after rivet pressing
  • Cycle time for pressing all three rivets after 'start' is pressed, should be <10 seconds
  • Tools/procedures should be provided for adjusting/maintaining rivet pressing force
  • Safety features should prevent extremities from getting within 4 inches of hydraulically actuated hardware during all operating cycles
  • Machine should be portable for re-positioning by one person within a work cell
  • Machine should run on a V power supply
  • Changeover between knife models should be less than 15 minutes
