Embodiment 1
[0084] The present invention is described in detail by taking the roll forging refined billet die of the front axle of the A680 type automobile as an example.
[0085] The mold includes an upper half mold and a lower half mold. The upper and lower half molds are symmetrically installed on the upper and lower rolls of the roll forging machine through the annular channel and the annular boss on the opposite surface respectively, and the upper and lower half molds The gap between them is 5mm, the central angle α of the upper and lower half molds is both 120°, the inner and outer radii and widths of the upper and lower half molds are 300mm, 495mm, and 265mm respectively, and the annular passage on one side of each half mold The inner and outer radii and groove depths of the grooves are 350mm, 399mm, and 8mm respectively, and the inner and outer radii and heights of the annular bosses on the other side of each mold half are 350mm, 399mm, and 8mm, respectively. There are 6 sections ...
