Machining process and machining die of shaft tube hollow tube

Abstract

The invention discloses a machining die for a shaft tube hollow tube. The machining die comprises an upper pre-upsetting die, a lower pre-upsetting die and an extrusion head. The lower pre-upsetting die can support a blank; when the upper pre-upsetting die and the lower pre-upsetting die are in a closed state and the extrusion head is located in a hollow portion between the upper pre-upsetting die and the lower pre-upsetting die under the effect of equipment, a cavity formed among the extrusion head, the upper pre-upsetting die and the lower pre-upsetting die is identical to the shaft tube hollow tube in structure. By applying the machining die for the shaft tube hollow tube, the forged shaft tube hollow tube blank is provided with a basically formed inner hole structure, so that the drilling time of subsequent machining can be shortened, the subsequent machining allowance is small, and then the machining time is shortened, and the cost is reduced. In addition, by applying the machining die, the problem that the machining difficulty of a traditional inner hole is high is avoided, and the production efficiency is improved remarkably. The invention further discloses a machining process of the shaft tube hollow tube, and according to the machining process, the machining die for the shaft tube hollow tube is adopted.
