Ironworker Prototype II Proposal

Analysis of Industry Standards

Summary

• The most common machines cost $18.5k-25k.
• They weigh between 4800 and 5500 lbs.
• The punch capacities are all at least 120 tons.
• All except the Uni-Hydro can flat shear up to 1"x12", and most have 24" blades.
• All can shear at leas 1/2"x6"x6" angle.
• Most machines shear the flat by an "angular" cut, meaning that the blade is rotating about some point.

Findings:

Most machines shear the flat by an "angular" cut. The closest design to the OSE objective is the Scotchman. It has a relatively simple construction, and enables quick re-tooling. The center table is desirable as big (up to 24" wide) attachments can fit inside, enabling even more diverse fabrication.
