Problems solved by technology

[0002] The casting process of the bearing connector is very complicated. However, in the current casting process of the crankshaft, the hardness of the finished casting is not enough. Not only are there many casting processes, which affects the production capacity, but the accuracy of the casting cannot be effectively guaranteed, and the scrap rate is high.

Abstract

The invention discloses a casting process of a high-strength bearing connector, which comprises the following steps: (1) using resin sand as a raw material, (2) using the resin sand to make a sand mold, and forming a resin sand mold after matching a mold box; (3) ) making pouring liquid, (4) heating the above-mentioned raw materials to the smelting temperature in an electric furnace, (5) pouring the casting liquid into the resin sand mold through a centrifugal process, and forming a bearing connector casting after solidification; (6) The casting of the bearing connector in step (5) is processed and formed by machine tool finishing. The casting process of the high-strength bearing connector of the present invention is simple and of high quality.

Description

technical field [0001] The invention belongs to the field of manufacturing technology of a shaft coupling, and in particular relates to a casting technology of a high-strength bearing connector. Background technique [0002] The casting process of the bearing connector is very complicated. However, in the current casting process of the crankshaft, the hardness of the finished casting is not enough. Not only are there many casting processes, which affects the production capacity, but the accuracy of the casting cannot be effectively guaranteed, and the scrap rate is high. . Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to propose a casting process of a high-strength bearing connector, which is simple in process and high in precision. [0005] (2) Technical solution [0006] In order to solve the above technical problems, the technical solution adopted in the present invention...
