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