High precision blanking die and pneumatic laboratory punch press

 

Made to order

 

Specialty products like foil and very thin materials require special metal stamping tooling. We build custom, table top, laboratory or clean room shop air /presses and cathode and anode cutting dies for battery research.

 

Blanking thin foil type material is a challenge of its own. E.g., a 0.002 - 0.005 thickness stock to be blanked requires such small amount of cutting clearance that it is a very difficult task for most tool and die makers and for the equipment to do properly.

 

For this particular blanking punch die design the finished blank was made of three layers. There were two carbon film layers of 0.003 thick with a copper foil between 0.0005 thickness. The requirements were the following:

 

  1. The foil must be perfect, have no burr at all.

  2. Part is rejected if the carbon chips off from the metal.

  3. Part is rejected if the carbon is separated from the metal at any given area. 

 

The customer provided samples, made by others that did not meet the request and were then rejected.

 

  • The above criteria was achieved by using the right amount of cutting clearance for the blanking die design that this particular material needed.
     

  • To avoid separation of the layers, the blank must have the least amount of flexing.
     

  • To eliminate chipping of the brittle carbon layers that were only semi bonded to the copper were another challenge. The product need to be without burrs, peeling and edges must stay sharp.
     

  • A gentle even holding pressure was required to hold the material while it was blanked, while reducing the travel distance of the blank inside the die cavity.

 

To accommodate all of the above, the tool had to be well guided, with low impact movement with no vibration or sudden shocks.

 

The part was to be handled by lab technicians so the tool could be built for this "clean room" environment. 

 

The result was excellent as expected, and the parts came out perfect.

 

The combination of a good metal stamping die design and precision tool and die manufacturing was the key to this success.

Multi set up hole stamping die

 

Made to order

 

The multi set up metal stamping die punches holes and cuts parts to length from 1/8" and 3/16" thick, 1.25 wide aluminum flat bars. There are two tracks in the tool for the two different parts.

 

  • Part One: 12" long, has 4 holes and the end corners have radiuses as well.
     

  • Part Two: 32.75 long and has 8 different holes punched. The end corners also have radiuses.
     

The metal stamping die components were built into a two post guided die set with a foot print of 10.5 x 20.0. Since one of the part is nearly 33 inches long a supportive extension was added. The total length of the tool become 45 inches long. There were flip stops to control the lengths of each part.

 

The parallels under the die set to ensures proper slug evacuation. The parallels placed from front to back. The reason for it that it allows checking slug accumulations visually.

This tool is the first tool of two for the same project. The parts require bending which needed a special tool to make this operation as efficient as possible.
