Problems solved by technology

The liner manufactured by the compound cold extrusion plastic forming process can meet the requirements of fine and uniform grain size and good geometric symmetry. The forming pressure per unit area increases, and the hot-sticking phenomenon between the punch and the inner mold of the drug-type cover is prone to occur. At this time, the tiny wear powder formed adheres to the inner surface of the punch or the drug-type cover, and the compound extrusion process causes the drug The inner surface of the mold is strained, the surface roughness increases, and the quality of the formed medicine mold is not high, which has a significant impact on the armor penetration performance

Abstract

The invention belongs to the technical field of lubricating agents and discloses a lubricating agent for the combined-cold-extrusion plastic forming of a shaped charge liner and a preparation method of the lubricating agent. The lubricating agent comprises, by weight percentage, 2-8% of polyacrylamide high-molecular polymer, 1-3% of mixture of oleic acid malonate, 0.3-0.8% of sulfur phosphorus primary-secondary-alcohol-group zinc salt, 3-6% of mixture of carbamate and dialkylthiophosphoric acid derivatives containing nitrogen, 0.1-0.5% of n-octyl sulfur-based methylene, 0.2-0.5% of mixture of polydimethyl siloxane and polyether modified silicone oil, 2-5% of mixture of dialkenyl succinimide and ethyl acetate, 1-3% of mixture of magnesium naphthenate and potassium isooctanoate, 0.1-0.5% of mixture of polyaluminium ethyl siloxane and low-molecular-weight polyamide, 0.3-1.0% of butyl stearate, 1-4% of boric acid and the balance water. The lubricating agent is prepared by evenly mixing the substances above. By the lubricating agent, phenomena such as galling and cracking during the forming of the shaped charge liner can be avoided.

Description

technical field [0001] The invention relates to a lubricant and a preparation method, in particular to a lubricant for composite cold extrusion plastic forming of a drug-type cover and a preparation method thereof. Background technique [0002] A typical shaped charge jet has a high head velocity and a low tail velocity, and this velocity gradient makes the jet drawn very long at a considerable blast height. The penetrating ability of the jet is proportional to the length of the continuous jet, but the length of the continuous jet is limited because the jet eventually breaks into segments of particles in the axial direction. Once the jet breaks into particles, its penetration ability will decrease. Research institutions at home and abroad have done a lot of in-depth research on the relationship between the internal structure, manufacturing process and armor-piercing performance of the drug-shaped cover. The research shows that the grain size, grain orientation and other in...
