Research and Optimization of Machining Technology of Hammer Rod Subjected to Frequent Impact

Abstract In the oil exploration work, hammer rod as main component, due to insufficient strength of rod, head falling off, body bending deformation and copper layer off other problems often occur in which not only affects progress but also causes huge economic losses. Aiming at problem through analysis processing technology working environment it is concluded that there are design head, material selection body, layer. this regard, optimized, depth inner hole deepened, changed a taper hole; replace 2CrMo alloy steel with higher add heat treatment process after rough turning release residual stress inside body; scheme for replacing attached surface by means hot-mounted sleeve. The improved fully meets needs high-intensity impact shortens time, saves costs, makes great contributions work.
