Multi-part dovetail repair broach assembly and methods of use
InactiveUS6676336B2Easy to importInexpensive to fabricateRectilinear broachBroaching toolsImpellerTurbine wheel
The broach assembly includes alternate spacers and cutters arranged in a sub-assembly having a lead at a leading end and a lag at a trailing end. The cutters have side margins in excess of the margins of the spacers for cutting material from the dovetail slots of the turbine wheel as the broach assembly passes through the slots. The bottom or apices of each spacer and cutter are tapered to form a continuously tapered surface along the bottom of the broach assembly. Upon passing the broach assembly through the slot, the assembly is progressively displaced in a radial outward direction to progressively cut the active dovetail slot surfaces. Shims may be disposed in the bottom of the slot to further displace the broach assembly radially outwardly in multiple passes.

A broach has a main body of a cemented carbide material. On this main body, a front grip portion, a cylindrical portion following the front grip portion and provided with a plurality of guide parts in its outer periphery, a broach cutting edge portion following an end of the cylindrical portion and having a number of cutting edges, and a cylindrical extension following the broach cutting edge portion and having a maximum outer periphery dimension to such an extent that the extension does not interfere with a work are integrally provided. On an end surface of the cylindrical extension, a load receiving shoulder is formed, which leads to a rear grip portion including a small-diameter part and is orthogonal to or inclined with respect to a broach axis. The load receiving shoulder has a sufficient area to bear a cutting load. A broaching machine grips the rear grip portion with its load receiving surface abutting against the load receiving shoulder of the cemented carbide broach. The broach, even when having a small diameter, does not suffer from an insufficient tensile strength of the front grip portion.
