Embodiment

[0031] Such as figure 1 — image 3 Shown, a kind of cartridge case processing technology comprises the following steps:

[0032] Step S101, material selection: select materials of 680g-685g / piece;

[0033] Step S102, stamping: stamping the cartridge case to form, the total length of the formed cartridge case is 66±0.5mm, and the coaxiality between the formed cartridge case inner cavity and the outer shell is 0.5mm;

[0034] Step S103, roughing the left and right end faces: roughing the right end face of the cartridge case, the total length after roughing the right end face is The perpendicularity between the shell and the right end face of the rough-turned right end face is 0.15mm, the left end face of the rough-turned cartridge case, and the total length behind the rough-turned left end face is The surface roughness of the cartridge case is 12.5μm;

[0035] Step S104, the inner shape of the right end of the rough car: the drilling depth is The inner cavity at the ri...

Abstract

The invention discloses a cartridge case machining process which comprises the step a of material selection, the step b of stamping, the step c of rough turning of a left end face and a right end face, the step d of rough turning of the inner shape of the right end, the step e of finish turning of the inner shape of the right end, the step f of finish turning of the appearance, the step g of milling of a left groove R, the step h of drilling of a left hole, the step i of drilling of a small bright eccentric hole, the step j of surface treatment and the step k of encasement. According to the cartridge case machining process, the steps are further simplified, and machining accuracy can be guaranteed.

Description

technical field [0001] The invention relates to a processing technology, in particular to a bullet case processing technology. Background technique [0002] The existing cartridge case processing technology includes blanking, stamping, rough turning right end face, rough turning large outer circle allowance, rough turning left end section, rough turning right end inner shape, rough turning inner R spherical surface, finishing turning inner shape, finishing turning outer type, milling the R groove at the left end, drilling the hole at the left end, drilling eccentric bright small holes, surface treatment and packing. However, the existing shell casing processing technology is too complicated, and the accuracy is difficult to guarantee. Contents of the invention [0003] Based on this, in view of the above-mentioned problems, it is necessary to propose a shell casing processing technology with more simplified steps and guaranteed processing accuracy. [0004] The technical...
