Multi-channel adaptive pressure balanced ammunition press molding tooling

Abstract

The invention discloses a multi-channel adaptive pressure balanced ammunition press molding tooling which is mounted between a press upper sliding block and a mold. The multi-channel adaptive pressurebalanced ammunition press molding tool comprises a cylinder body, a plurality of plungers and a plurality of end covers; a plurality of plunger cavities are arranged in the cylinder body; the cylinder body is equipped with an oil passage, the plunger cavities intercommunicate through the oil passage; the end covers are arranged on the cylinder body; the plungers are arranged in the plunger cavities of the cylinder body and are limited by the end covers; the front ends of the plungers extend from the plunger cavities; the plungers can slide freely and stretch in the plunger cavities. The tooling disclosed by the invention can achieve batch press molding of ammunition and further improve the production efficiency of the ammunition; in addition, the tooling has no excessive high requirementon the parallelism of the press and can ensure the uniformity of batch pressing.

Description

technical field [0001] The invention relates to the technical field of ammunition pressing and forming tooling, in particular to a multi-channel self-adaptive pressure balancing ammunition pressing and forming tooling. Background technique [0002] Charging is the most critical process in the production of ammunition. It makes explosives into high-density grain columns to facilitate long-term storage and meet operational requirements. The press-packing method is one of the commonly used methods for ammunition charging. It uses the principle of press molding to put granular explosives into the mold, apply a certain pressure with a punch, and press the granular powder into a shape with a certain density. and mechanically strong grains. The cost of the press-packing method is low, and a charge with a content of more than 90% can be obtained. The detonation wave sensitivity is high, and it is easy to generate "hot spots" that develop into detonations, and are widely used in boo...

AI Technical Summary

Problems solved by technology

But at present, the press-fitting method can only be produced in a single piece, one mold is pressed at a time, and one grain is pressed into shape. The production efficiency is very low and cannot meet the demand, and the press is required to have a high degree of parallelism to achieve precise pressing.
