Manufacturing method of large conical ring piece

Abstract

The invention relates to the technical field of intelligent construction, and discloses a manufacturing method of a large conical ring piece. The manufacturing method comprises the following steps that 1, the size is designed, specifically, the small end face size, the large end face size and the taper of the conical ring piece are designed according to actual size requirement data; 2, a blank mold is designed, specifically, the blank mold is designed according to the designed small end face size, the large end face size and the taper of the conical ring piece; 3, a primary blank is forged, specifically, a metal ingot is selected according to the actual using environment and the using requirement of the conical ring piece, the metal ingot is forged through a forging machine according to the hardness, the plasticity and the ingot type of the selected metal ingot, and a rough blank is obtained for standby application after forging is completed; and 4, the rough blank is subjected to finish forging, specifically, the rough blank is subjected to finish forging through a forging cogging hydraulic machine, and loosening, shrinkage cavities and microcracks in the rough blank are forged. According to the manufacturing method of the large conical ring piece, the manufacturing qualification rate of the large conical ring piece is effectively increased, and the cost of large-batch production of the large conical ring piece is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent construction, in particular to a method for manufacturing a large tapered ring. Background technique [0002] Large tapered rings are key parts of many heavy machinery, power generation equipment, petrochemical, shipbuilding and other industrial equipment. The processing of large tapered rings requires forging, ring rolling and rolling. [0003] In the actual production of the existing large-scale tapered ring manufacturing process, due to the cumbersome production steps, the product is prone to large errors in each manufacturing link, resulting in poor quality of the final product, resulting in product The pass rate is low, resulting in waste of production resources and increased manufacturing costs.
