Steel Stamped Fuse Bracket for Electrical Equipment Industry

Material of construction was .187” thick hot rolled pickled and oiled steel sheet, an economical choice for applications such as this that require a clean, uniform surface and good flatness.

Utilizing hardened tool components in conjunction with our standard units and holders, we performed a series of coordinated blanking, piercing, and forming operations using five different punch presses. Since each operation is done with a single hit, we were able to exactly duplicate the geometry from the first unit to the last. To finish the parts, we applied a .002” thick hot white zinc dip coating to provide immunity from corrosion, which has the potential to cause great harm in electrical applications.

When completed, the fuse brackets measured 6.0” in length x 5.305” in width x 6.4” in height, and tight control over the forming processes enabled us to uphold ±.005” tolerances on all dimensions. By eliminating the need for a normal die set, we kept the tooling costs to a bare minimum for this heavy duty part.
