Abstract

The invention discloses automatic ammunition primer press fitting equipment, and relates to the field of ammunition production. The automatic ammunition primer press fitting equipment comprises a shell case feeding module, a primer feeding module, a primer press fitting module and a shell case radial clamping module, wherein the shell case feeding module, the primer feeding module, the primer pressing fitting module and the shell case radial clamping module are arranged coaxially from top to bottom; the shell case feeding module comprises a shell case feeding device and a shell case conveyingdisc, and the shell case feeding device conveys shell cases into the shell case conveying disc one by one; the primer feeding module comprises a primer feeding device and a primer disc, a plurality ofcylindrical through holes are formed in the periphery of the primer disc, a supporting piece is arranged at the bottom of the primer disc and is connected with the primer disc through a first elasticpart, and the primer feeding device enables primers to fall into the supporting piece located at the bottoms of the cylindrical through holes; the primer press fitting module comprises a primer pressfitting disc and a primer pressing rod, and the primer is pressed into the shell case; and the shell case radial clamping module comprises a wedge cam and a radial clamping device, and the wedge camand the shell case conveying disc are coaxially arranged, and the radial clamping device is arranged on the shell case conveying disc. The automatic ammunition primer press fitting equipment improvesthe press fitting efficiency of the primer.

Description

technical field [0001] The invention relates to the field of ammunition production, in particular to an automatic press-fitting device for ammunition primers. Background technique [0002] Ammunition is one of the most basic and most demanded products in the defense industry. The quality of ammunition often determines the trend of the battle situation, and its importance is beyond doubt. my country's ammunition manufacturing technology is developed on the basis of introduction, digestion and absorption. The research on automatic assembly technology is relatively late, and the technology is not perfect. At present, the production method of small-caliber ammunition in my country is mainly a linkage production method, that is, single-machine equipment and unit equipment are used, and equipment with different functions is combined through transmission chains and other link methods to assemble ammunition, which is costly and requires manual labor. Intervention operation. The exi...
