Embodiment Construction
[0027] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] combine figure 1 As shown, the large thin-walled special-shaped casting cabin shell disclosed in this embodiment is an important product on a certain type of missile, and is the key to ensure reliable connection and separation of the missile during ground lifting, transportation, and booster flight. The front end of the shell is a non-circular special-shaped section, the outer diameter of the outline is 600mm-700mm, and the rear end is a circular end frame with a diameter of φ1400mm. The taper is about 20°, and the typical wall thickness is 3mm.
[0029] The processing method of the above-mentioned large thin-walled special-shaped cabin shell comprises the following steps:
[0030] The first step is to reserve a reference boss on the shape of the shell when casting the shell, rough machining the marking benchmark, level the front and rear end faces of the she...
