Production method and forge die of high-speed train brake disc

Abstract

The invention discloses a production method and a forge die of a high-speed train brake disc. The forge die comprises an upper die and a lower die, wherein an upper die heat radiation rib cavity of the upper die and a lower die cavity of the lower die are matched to form a sealed cavity, and the cavity corresponds to the structure of the brake disc; a cushion plate is further arranged at the bottom of the lower die, the diameter of the cushion plate is equal to that of the lower die cavity, and the structure of the upper surface of the cushion plate corresponds to the structure of the upper die heat radiation rib cavity one to one. When a brake disc blank is forged, the sealed cavity is filled with metal through extrusion of the cushion plate. According to the production method and the forge die of the high-speed train brake disc, a low-tonnage friction screw press is adopted and can satisfy a forging brake disc blank which can be machined only by a press above 15000 tonnage originally, the two ends of a heat radiation rib on the brake disc are prevented from being lost, contraction deformation generated in the cooling process is avoided, production cost is lowered, and production efficiency is improved.

AI Technical Summary

Benefits of technology

This new design allows for better performance when processing large amounts of material due to its small size but avoids any issues such as warping or distortion caused from heated materials being worked on at high temperatures. Additionally, it prevents excessive pressure applied while cooling the metal plate without causing damage. Overall, this technology improves productivity and reduces costs associated therewith

Problems solved by technology

This patented technical problem addressed by this patents relates to developing an improved brake system for high speeds without sacrificial issues like wear or damage caused during operation due to inspections from foreign objects. Existing methods involve expensive capital investments while also requiring significant labor resources.
