Problems solved by technology

Due to the structural characteristics of the large flange, thin-walled blind hole, and large aspect ratio of the explosive cartridge, there are two problems in this processing method: one is the poor rigidity of the part, and the vibration of the tool during the processing causes the roughness of the inner hole of the part to be low , it is difficult to ensure the safety of the assembly of the booster; second, the material utilization rate is extremely low, only about 10%, and the processing cost is relatively high

Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to facilitate a clearer understanding of the present invention, but they do not limit the present invention.

[0039] Such as figure 1 , figure 2As shown, for a certain missile, the overall detonation warhead charge body booster cartridge parts include cartridge 2 (that is, the part of the booster cartridge with thin wall and large aspect ratio), and the plug 1 at one end of the cartridge 2. And the flange 3 at the other end of the cartridge 2, its large flange (diameter Thickness 12mm), thin-walled blind hole (wall thickness and bottom thickness 4mm), large aspect ratio (inner hole diameter The forming process of length 736.5mm) is as follows:

[0040] 1) Formed cap assembly 4: The cap assembly is formed by processing an aluminum rod. The cap assembly 4 includes a cap 1 at the big end and a process chuck 5 at the small end,...

Abstract

The invention discloses a processing method of aluminum alloy booster explosive cartridge class parts. The booster explosive cartridge case class parts are divided into three technology parts of a blanking cap, a cartridge case, and a flange. The blanking cap and the cartridge case are machined and welded into a cartridge case component, then a processing scheme of threaded connection, gumming, solidification and anti-rotation is implemented on the cartridge case component and the flange, through the machining method of alternating a vehicle peripheral circle, bore inner holes, the middle section of self-made annular work tool clamping parts peripheral circle, the tool vibration problem caused when a thin wall deep hole structure is poor in rigidity in the process of processing inner holes of bores is avoided, the roughness of the inner holes is improved, the molding demands of aluminum alloy materials, large flanges, thin wall blind holes and high draw ratio booster explosive cartridge class parts are met, and the problems that the roughness of the inner holes is low, the assembly security of the booster explosive explosives is not guaranteed, and the material utilization rate is low are solved.

Description

technical field [0001] The invention belongs to the technical field of cylinder-type parts processing, and specifically refers to a processing method for aluminum alloy explosion-boosting cartridge-type parts. Background technique [0002] The explosive transfer cartridge is the structural part of the explosive transfer component of the warhead charge body. The charge body is filled with a large number of high-energy explosives. By receiving the output energy of the detonation system, the explosive transfer component is detonated. The explosive transfer component detonates the main charge and acts as an explosive. Afterwards, a shock wave overpressure is generated to kill the target. Among them, the booster cartridge is an important structural part for installing the booster, the booster fuze, and connecting with the shell of the charge body. [0003] At present, the processing method of the explosive cartridge is mainly to use aluminum alloy rods to be directly machined in...
