Press Maintenance and Fundamentals of Press Capacity Seminar

Tuesday, September 18, 2012

Minneapolis, MN

What is the press designed to do?

Reduce your maintenance.

Is the problem with the tool or the press?
Use the right tool for the job.

You will learn:

Metal Stamping Press Maintenance & Troubleshooting

  • How to quickly make adjustments to the die space to isolate the press problems from the tool
  • How to maximize uptime, even with less than perfect machinery
  • The Theory of the Box
  • Safe metal stamping press operations
  • The full understanding of the design and use of metal stamping presses
  • Efficient and practical preventive maintenance inspection procedures
  • Comparison between hydraulic and mechanical presses and their use
  • Different types of parts that can be produced
  • The importance of proper level and alignment of the press bed and/or frame
  • Terminology overview
  • Troubleshooting

Understanding press capacity

Forward tonnage:

  • Define forward tonnage
  • Show how the mechanical press develops forward tonnage
  • Explain concentrated load and its effect on tooling that can be run
    • Show how to calculate this
    • Review various methods to mitigate the issue
  • Explain off center loading and its effect on tooling that can be run
    • Review symptoms that reveal this capacity is being exceeded
    • Show how to calculate this
    • Review various methods to mitigate the issue

Reverse tonnage

  • Define reverse tonnage
  • Review types of stamping processes that develop reverse tonnage
  • Review symptoms that reveal reverse tonnage capacity is being exceeded
  • Review methods to reduce reverse load generation
    • Tooling methods
    • Shock dampening strategies
    • Press selection
    • Servo Press technology

 Torque

  • Explain the torque curve and its impact on tooling that can be run
    • Why is there a torque curve?
    • Review symptoms that reveal this capacity is being exceeded
    • Review impact of stagger on torque curve

 Energy

  • Define energy
  • Show how energy is stored on mechanical and servo presses
  • Review mechanical press designs and the impact on energy capacity
  • Review applications and calculate energy requirements
  • Review symptoms that reveal energy capacity is being exceeded
  • Review the impact of Servo press technology on traditional energy considerations

 Ram velocity

  • Review calculation, demonstrate effect of stroke length on speed in crank motion presses
    • Review tooling processes and the effect of velocity on various processes
    • Review impact of servo technology on the traditional limitations

 Servo press technology

  • Review traditional balancing of tonnage, velocity, energy, torque, stroke length, automation and SPM output
  • Examine impact of the servo press’s capabilities on th
