Abstract

The invention discloses a one-mold two-piece forging mold and method for a drill pipe joint. The mold comprises an upper mold, a lower mold, a first upsetting punch and a second upsetting punch, wherein the lower mold is located right below the upper mold; the first upsetting punch and the second upsetting punch can be correspondingly arranged on the two sides of the lower mold in a horizontal moving manner; the upper mold comprises an upper mold seat, an upper mold sleeve and an upper mold core; the lower mold comprises a lower mold seat, a lower mold sleeve and a lower mold core; molding bosses are correspondingly arranged in middles of the upper mold core and the lower mold core, and molding cavities matched with the shape of the drill pipe joint are arranged on the upper mold core and the lower mold core and located on the two sides of the molding bosses. The one-mold two-piece forging mold can be used for performing one-mold two-piece forging on the appropriate drill pipe joint, so that the forging process of the drill pipe joint is simplified, the machining efficiency is improved, and the machining cost is reduced.

Description

Technical field [0001] The invention belongs to drill pipe processing technology, and particularly relates to a two-piece forging die and method for a drill pipe joint. Background technique [0002] At present, the existing drill pipe joint processing mostly adopts one-die forging scheme, and the main steps are: blanking-heating-billet making-die forging-punching-post-forging treatment-roughing-heat treatment. This forging method has the disadvantages of complex process, low processing efficiency and high cost. Summary of the invention [0003] The purpose of the present invention is to provide a one-die two-piece forging die for drill pipe joints, which can simplify the forging process of drill pipe joints, and has the characteristics of high processing efficiency and reduced processing costs, so as to solve the problem of one die for drill pipe joints in the prior art. One of the above-mentioned problems in the forging process. [0004] Another object of the present invention is...
