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, polish and clean the welding surface of the cleaned cylinder body and other parts of the shell, 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 raw mate...
