Plate, the lower die is substantially square, and the top of the lower die is arranged at the lower die formed with boss and groove, the positioning plate
One end, top of the upper mold to be arranged at the lower die in a manner of can doing the reciprocating motion of vertical direction, faces described
Groove；By the radome fairing clamping of a pair of notch to be punched in the outside of the lower die, make the radome fairing of a pair of notch to be punched with
The lower die is tight fit, and the upper edge of the radome fairing of a pair of notch to be punched is born against in two sides of the boss
Wall, the rear end face of the radome fairing of a pair of notch to be punched are resisted against on the positioning plate, so that a pair of notch to be punched is whole
The position to be punched of stream cover is vacantly arranged at the top of the groove；
Step 4: manually the pressure bicker, move downward the upper mold, until the upper mold move to it is described recessed
In groove, so that the position to be punched of the radome fairing of a pair of notch to be punched be punched, and notch is formed at position to be punched.
Preferably, in the radome fairing punch press process method, provided in the step 3 on various sizes of two
Mould, and provide two different grooves of position, each upper mold correspond to each groove, after the upper mold for replacing another size, then carry out
Step 4, punching form another various sizes of notch.
Preferably, in the radome fairing punch press process method, in the step 3, the lower part both sides of the lower die are opened
There is side groove, the lower side of the radome fairing of a pair of notch to be punched is respectively clamped into two side grooves, and each notch to be punched
The lower edge of radome fairing be resisted against the bottom of corresponding side groove.
Preferably, in the radome fairing punch press process method, in the step 2, after plutonic type is drawn, also into
Wardrobe portion part corrugation smoothing, draw head configuration line, draw notch line, saw length, cut head configuration by line, repair filing it is whole with
And the more clouts of mill off two sides stile, then obtain the radome fairing of notch to be punched.
Preferably, in the radome fairing punch press process method, after the step 4, further include：Step 5: milling is convex
The dovetail groove of muscle portion position.
Preferably, in the radome fairing punch press process method, after the step 5, further include Step 6: drawing tail
Portion oblique angle line, surplus is cut off by line, draws the head slotted hole position line, drilling, and repair file slotted hole.
Radome fairing punch press process method of the present invention avoids part milling using the processing method of mould punching notch
Add the problems such as post-construction deformation is serious, burr is big, processing quality is greatly improved；Added at the same time using a mould two pieces when being punched notch
Work, greatly improves radome fairing notch processing efficiency, reduces operator's labor intensity, saves production cost.
