Draw Dies

Dave G:
A side view of the blank. The blank is on top and a finished part was used to prop it up.

Dave G:
Since the edges of the blank are irregular they will need to be trimmed before the second op. A trim fixture was made. The blank fits onto the fixture and then the edges are filed to size using the fixture as a guide.



From here our blank needs to have another lip formed on it, this will be the second draw operation.

The second pic of the blank seems to be after the second operation and it shouldn'd have this lip on it at this point.

Dave G:
The second operation draw die components. The die is on the bottom, the support is above the die and the punch is on the left.



The brass blank has been trimmed to size and is ready for the second draw. This draw will form a lip for strength and will form a pocket for the mating piece to fit into easily to provide a good solder joint.

Dave G:
The brass blank has been inserted into the support. The support will be inserted into the die and it will float in the die. When the punch is pressed down the support will float with the blank until it reaches bottom and then it becomes a coining plate.

Dave G:
The blank inserted into the die and the punch positioned on top. Everything has been lubed well and placed into the press. This pic shows the blank before forming the second op in the press.



This pic shows the punch at the bottom depth of travel and the lipped formed.
