Embodiment approach

[0054] In the first specific embodiment, the shaft tube hollow tube processing technology provided by the present invention includes the following steps:

[0055] Blanking, preparing a tubular blank with an inner diameter of 32-34mm;

[0056] Therefore, the blank is a pipe fitting with an inner hole, which is conducive to reducing the machining allowance and shortening the processing time in the subsequent processing. Specifically, the height of the blank can be set to 330mm, the outer diameter is generally 65mm, and the inner diameter can be set to 33mm. Of course, other settings can also be made according to specific needs.

[0057] heating the billet;

[0058] It is heated to facilitate the smooth progress of the subsequent extrusion process.

[0059] Clean the scale of the heated billet;

[0060] The blank is passed through the shaft tube hollow tube processing die provided in the above embodiments to forge the inner hole and extrude the shape.

[0061] The blank is p...

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.
