Embodiment Construction

[0017] The machining process of the engine housing of the present invention comprises the following steps:

[0018] (1) Raw material forming: clean and dry the raw material, plastically deform and form, roll the formed material into a cylindrical cylinder according to the size with a tube coiler, and process other parts of the engine housing on a lathe;

[0019] (2) Welding: Clean, dry and fix the cylindrical cylinder body, grind and clean the welding surface of the cleaned cylinder body and other parts of the engine housing, and perform seamless welding after drying;

[0020] (3) Inspection: Detect whether there are cracks and defects in the welded shell, check the accuracy of the shell and whether there is a weld;

[0021] (4) Finishing: Grinding the surface of the shell, removing the oxide layer, and then spraying primer, topcoat, and engraving.

[0022] Preferably in this embodiment, the welding is laser seamless welding.

[0023] Preferably in this embodiment, when the ...

Abstract

The invention relates to an engine case machining process. The engine case machining process comprises the following steps: (1) raw material formation: a raw material is cleaned and dried, and is formed by plastic deformation; the formed material is rolled into a cylinder according to the size by a pipe rolling machine; and parts at other portions of an engine case are machined on a lathe; (2) welding: the cylinder is cleaned, dried and fixed; the welded surfaces of the cleaned cylinder with other parts of the case are polished and cleaned; and then seamless welding is performed after drying; (3) detection: the condition whether the case formed after welding has cracks and defects is detected; and the precision of the case and the condition that whether weld seams exist are checked; and (4) finish machining: the surface of the case is polished to remove an oxidation layer; then, primer and finishing coat are sprayed; and the lettering is performed. The machining process can guarantee the precision and the quality of the engine case, and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a processing technology for an engine casing. Background technique [0002] The engine is the power device of the missile, and it is also an important part of the missile body. The engine casing, as the engine combustion chamber, has to withstand various complex loads under high temperature, high pressure and chemical atmosphere during work, and the working environment is very harsh. Therefore, the engine The processing technology of the shell is very important to the safety of the engine and the whole missile. The engine casing is required to achieve good rigidity, high strength, light weight and good surface quality. The existing manufacturing technology of the engine casing cannot fully meet the requirements. Contents of the invention [0003] In order to solve the existing technical problems, the invention provides a processing technology for the engine casing. [...
