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.

Abstract

The invention discloses a multi-channel self-adaptive pressure-balanced ammunition pressing and forming tooling, which is installed between the slider and the mold on the press, and includes a cylinder body, a plurality of plungers and a plurality of end caps, and is mounted on the cylinder body There are multiple plunger chambers, and there are oil passages in the cylinder body, the plunger chambers communicate with each other through the oil passages, the end cover is installed on the cylinder body, and the plunger is installed in the plunger chamber of the cylinder body to limit position, and the front end of the plunger protrudes from the plunger chamber, and the plunger can slide and expand freely in the plunger chamber. The tooling of the present invention can realize batch pressing and forming of ammunition, thereby improving the production efficiency of ammunition, and has no excessive requirements on 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...
