Problems solved by technology

However, in order to facilitate the processing, slag removal and post-processing in the existing technology of the brake disc using metal additive manufacturing technology, its heat dissipation rib structure is still the traditional spoke-like strip structure, and the upper disc surface and the lower disc surface The cross-section of the heat dissipation ribs has multiple edges and corners, and there is a serious stress concentration phenomenon, which reduces the service life of the brake disc

Abstract

The invention provides an alloy steel brake disc manufactured by laser additive material and a manufacturing method thereof. The brake disc comprises an upper disc surface (1), a lower disc surface (2), a claw structure (3) and a heat dissipation rib (4). ), it is characterized in that, described radiating rib (4) comprises middle cylindrical section and two circular arc transition sections that smoothly transition and connect with the upper and lower ends of the cylindrical section, the upper disk surface (1) and the lower disk surface ( 2) There is an inner flow channel (9) connecting the m radiating rib inner cavities (7) corresponding to the m radiating ribs (4), the inner and outer edges of the upper disk surface (1) and the lower disk surface (2) There are a plurality of inner flow channel outlets (8) on the surface respectively, and the inner flow channel (9) is communicated with the inner flow channel outlet (8). The alloy steel brake disc and the manufacturing method thereof of the present invention adopt a cylindrical and hollow radiating rib structure, which is simple in structure and light in weight, and improves the stress concentration phenomenon during processing.

Description

technical field [0001] The invention belongs to the technical field of high-speed train braking systems, and in particular, the invention relates to an alloy steel brake disc manufactured by laser additive materials and a manufacturing method thereof. Background technique [0002] The brake disc is one of the core working parts of the high-speed train braking system, which ensures the safety of life and property of passengers. As the speed of the train continues to increase, the brake disc is required to be lightweight and have better braking performance. The heat dissipation methods of the brake disc mainly include heat convection, heat conduction and heat radiation. The heat dissipation of the heat convection method accounts for 65% to 75% of the total heat dissipation, and the proportion increases with the increase of speed. Reasonable brake disc structure design is beneficial to improve the convective heat transfer capacity of the brake disc. At the same time, the light...
