F302-F303

Die set F302-F303 has its own locating gauge so the operator does not have to hold the part during the closing operation. This gauge also prevents the part from slipping out of the dies. With metals having large springback, the closed edges will open considerably. If the seam is to be welded closed, a welding jig or fixture will be necessary.

F142-F143

The F142-F143 set is usually used to form seams over 1/2" high. Tightness of the seam is controlled by shimming under the adjustable anvil.

F144-F145 and F146-F147

Double-flange standing seams are formed in the F144-F145 and F146-F147 sets in two operations. The first operation is performed in die set F144-F145 and the closing operation in die set F146-F147. Die sets can be produced with matched shut heights for progressive forming if the press brake has sufficient length.

F148-F149

The F148-F149 set is used to form a standing seam in two operations. The top station forms an acute angle offset, which is subsequently closed at the lower level.

F152-F153

A standing seam can be made with the F152-F153 set. The acute angle is subsequently flattened in another die and operation.

Illustration E

A four-way die held by a combination die holder is shown in the illustration. General-purpose dies can be substituted for the four-way when it is removed.

Illustration F

A general-purpose die can be used directly over a combination die holder provided the press has sufficient stroke (or ram adjustment).

Illustration G

A filler block may be required when the combination holder is low and the press does not have sufficient stroke (or ram adjustment) to close the tool set.

Illustration H

The four-way die can be set directly on the bed of the press if it does not have sufficient open height. This practice is not recommended, due to the potential for damage or wear of the bed surface.

Four Way Die - Illustration A

Multiple openings can be machined into a single steel bar. These dies are typically used to replace single-vee dies and can significantly reduce die-change time.

Four Way Die - Illustration B

Multiple openings can be machined into a single steel bar. These dies are typically used to replace single-vee dies and can significantly reduce die-change time.
