Grinding method for high-forming-precision seal head

Abstract

The invention provides a grinding method for a high-forming-precision seal head. The grinding method for the high-forming-precision seal head comprises the following steps that (1) an area, located onthe same circumferential zone, on the seal head is uniformly divided into several wall thickness detection areas; (2) a polishing belt is used for polishing the surfaces of the wall thickness detection areas for several rounds; (3) the wall thickness of each wall thickness detection area is detected, and the wall thickness detection area with the relatively thin wall thickness is marked; (4) a thin plate made of the same material as the seal head is pasted on the polished surface of the relatively thin wall thickness detection area; and (5) the polishing belt is used for polishing the surfaces of the wall thickness detection areas again for several rounds. The grinding method for the high-forming-precision seal head has the advantages of being capable of meeting the requirement of the seal head in the high precision field and being used for forming the high-precision seal head.

Description

technical field [0001] The invention relates to a high-precision head forming method, in particular to a high-precision head grinding method. Background technique [0002] Ordinary heads do not require high molding precision, as long as the thickness of the head is not lower than the required thickness. Therefore, the general head can meet the use requirements after folding; but for some high-end aerospace and other high-end field, there are strict requirements on the shape of the head, the wall thickness of each part, and the material performance of the head. A few millimeters, and the allowable error is not more than 0.2mm. At the same time, the material properties and uniformity of the head must be guaranteed. However, there is no method for forming such a high-precision head in the prior art. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The purpose of the present inven...

Several millimeters, and the allowable error is not more than 0.2mm. At the same time, it is necessary to ensure that the material performance and uniformity of the head are strictly required. However, there is no method for forming such a high-precision forming head in the prior art.
