Problems solved by technology

[0007] The above-mentioned process method has disadvantages: the grains of the prepared drug-type mask are relatively coarse, usually above a few microns; the cathode is easy to absorb air bubbles, thereby generating pores in the deposited metal; the deposition rate is low

Abstract

With core mould of the gunpowder typed cup being rotated, the feed flow of the electroforming fluid carries out from bottom part of the core mould. The anode with shape similar to the shape of the core mould of the medicine-typed cover is made with insulation material. The anode combines with the blocky electroform material of the anode to constitute the anode cavity as the anode unit. The rolling depression or the friction and disturbance treatment is carried out for the core mould of the cathode in rotating electroform by using the rolling depression method or the insulation friction method. The device includes the stock solution tank, the magnetic drive pump, the filter, the ball valve etc. The equipment also includes the rotating cathode, the rolling depression set or friction set, the imitating anode etc constituted the device of the electroform procedure.

Description

Technical field: [0001] The electroforming manufacturing process and device of the drug-type cover of the present invention belong to the electroforming manufacturing method and device of the drug-type cover. Background technique: [0002] Shaped charge structures are widely used in fields such as oil exploitation, civil blasting, and armor penetration of tanks. The liner is a key part of the shaped charge structure, generally a conical rotator of metal material with a certain wall thickness. During the working process of the shaped charge structure, the high temperature and high pressure generated by the explosive make the drug cover into a columnar high-speed metal jet. When it hits rocks, concrete or armor, it can generate a local pressure of more than 100,000 MPa. It penetrates to achieve the purpose of penetration. The penetrating and penetrating ability of the shaped charge structure is closely related to the material performance, shape and precision of the medicine-...
