Abstract

The invention discloses a light flange plate hub and a machining process thereof, and belongs to the field of flange plate hubs. The light flange plate hub and the machining process thereof comprise aflange plate basal body; a center through hole is drilled in the center of the flange plate basal body; an annular limiting part and a reinforcing projection matched with the center through hole arearranged in the center of the flange plate basal body; the annular limiting part and the reinforcing projection are integrally molded with the flange plate basal body to reduce the cost; the reinforcing projection is positioned on the outer side of the annular limiting part; multiple outer holes are drilled in the flange plate basal body between the annular limiting part and the reinforcing projection; a pair of U-shaped grooves is drilled in the reinforcing projection; and the center through hole and the outer holes are punched by adopting a punching auxiliary device, so that the deformationcan be prevented, the generation of punching burrs on non-machined surfaces is greatly prevented, single burr inspection and burr removal are not needed, the burr inspection is safe and simple, and the traditional burr inspection intensity is reduced.

Description

technical field [0001] The invention relates to the field of flanged hubs, more specifically, to a lightweight flanged hub and its processing technology. Background technique [0002] Flanges, referred to as flanges for short, are parts used to connect pipes to pipes. Bolt holes are provided on the flange, and the two flanges are tightly connected by bolts to realize the butt joint of the two pipes. However, the existing flanges produced by casting or forging processes have low structural strength, especially near the bolt holes, and are prone to damage after long-term use, resulting in limited service life of the flanges. Moreover, in order to meet the requirements of energy saving and emission reduction, various components are developing towards lightweight. However, it is difficult to form more complex structures at one time by using traditional casting or forging processes, so it is difficult to meet the requirements of lightweight and structural strength. In order to ...
