A kind of preparation method of three-prong bracket and three-prong bracket

Abstract

The invention belongs to the technical field of aerospace equipment accessories, and discloses a manufacturing method of a tripod and the tripod. The manufacturing method of the tripod comprises the following steps that A, a cylindrical blank made of a nickel-iron alloy is provided, and heating is carried out on the blank; B, the blank is forged into an orthohexagonal prism; C, material segregation operation is carried out on the blank in the circumferential direction through a material segregation roller to obtain a blank body and three supporting legs fixedly connected to the blank body, andthe three supporting legs are uniformly distributed in the circumferential direction of the blank body; D, drawing operation is carried out on the three supporting legs to enable the three supportinglegs to extend in the radial direction of the blank body; and E, bending operation is carried out to enable the three supporting legs to be bent in the same direction relative to the blank body, andthe tripod is obtained. The tripod is manufactured through the manufacturing method of the tripod. According to the manufacturing method, the overall structure of the tripod is directly formed in a free forging mode, so that the production and manufacturing cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment accessories, in particular to a preparation method of a tripod bracket and the tripod bracket. Background technique [0002] Super Invar, also known as Invar, is a nickel-iron alloy with an extremely low coefficient of thermal expansion and can maintain a fixed length in a wide temperature range. It plays an important role in the aerospace field. [0003] In aerospace equipment, trident brackets made of nickel-iron alloy are the main components that support the window glass on the viewing window. During the whole process of aerospace equipment rising from the ground to the air, the service conditions change rapidly, and the working environment such as high temperature and freezing exists alternately. At this time, in order to ensure the stability and safety of the aerospace equipment structure, it is necessary to ensure The structure is reliable. Among them, due to its special materi...

AI Technical Summary

Problems solved by technology

Among them, due to its special material and structural characteristics, the window glass is not easily deformed during the entire service process, thus correspondingly increasing the performance requirements for the tripod bracket. If the tripod bracket is deformed, the window glass attached to it will be damaged. Seriously affect the safety of aerospace equipment

[0004] The trident bracket is large in size and complex in structure. Due to its special function, it must be manufactured as a whole. If it is manufactured by welding, it is easy to deform due to the difference between the welding port and the body. If it is manufactured by machining, Large processing volume, low material utilization rate, long production cycle and high production cost
