Embodiment Construction

[0036] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] (1) Material preparation: Prepare the plate with the required thickness according to the requirements of the drawing. The thickness of the plate is consistent with the final material thickness of the part. The thickness of the wool when cutting the material must be the final part thickness, so as to ensure the final part thickness. The part is formed The material thickness reduction in the process meets the requirements, and there will be no excessive reduction in material thickness;

[0038] (2) Laser blanking: refer to the final shape of the part, and determine that the part wool is ring-shaped wool;

[0039] (3) Paint spraying: form a protective film on the surface of the parts to prevent direct contact between the parts and the mold, and play a protective and lubricating role;

[0040] (4), the first moldi...

Abstract

The invention discloses a processing device and a processing method for the head of a flame tube. Using an annular blank, the annular blank is first put into a forming mold to form a U-shaped structure, then heat-treated, and then stretched to form the convex hull of the flame tube, which is assembled by a processing device. Clamp the part, process the end face of the car, and mill the convex hull without disassembling the clamping device. When milling the convex hull, press the convex hull at intervals, mill the uncompressed convex hull first, and then compress the milled convex hull , and then mill the remaining convex hulls, using the method of milling multiple convex hulls at the same time. The invention has the advantages of simple processing method, short processing period, low processing cost and good processing quality.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing method and a processing device used for the head of a flame tube. Background technique [0002] The head of the aero-engine flame tube has a U-shaped ring in cross-section. The diameter of the part is greater than 700mm, the total height of the part is greater than 25mm, and there are more than 20 flanging holes (convex hulls) evenly distributed on the top of the part. Due to the large diameter of the part, And the surface structure is complex, and the parts are allowed to be welded with three welds. However, the parts are prone to poor welding matching and welding deformation during the welding process, and it is difficult to guarantee the final processing requirements and dimensional accuracy of the parts. Therefore, studying a reasonable and feasible process method and unique tooling is an inevitable choice for forming similar parts. Contents of the...
