The invention discloses iron alloy breaking machining equipment. An iron alloy raw material block in a feeding hopper is screened to the breaking sizes adapting to different impact modules by an automatic screening and feeding device, and is automatically conveyed to an impact breaking machining line in the corresponding size; a single iron alloy is centered and clamped to the impact position of impact breaking equipment by an iron alloy locating and clamping device; the iron alloy raw material block after being located is subjected to impact breaking operation by an impact breaking device according to the impact times and frequency which are set by programs; and after the impact breaking operation is completed, the iron alloy after being broken is discharged into a finished product hopperby an automatic discharge device. The whole iron alloy breaking machining adopts the automatic operation, and the production efficiency of the iron alloy breaking machining equipment is high; and theiron alloy is broken by adopting an impact breaking mode, so that the problem that the dust rate is too high in the breaking process of the iron alloy can be solved greatly, and the machining and production benefits of the iron alloy are improved. The invention is applied to the iron alloy breaking equipment.
