Problems solved by technology

Therefore, the processing of the inner tank of integral stretch molding is complicated, the cost is high, and the work efficiency is low.
[0004] This shows that above-mentioned existing pressure vessel obviously still has inconvenience and defect in manufacturing method and use, and urgently needs to be further improved
In order to solve the problems existing in the existing technology, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general manufacturing method has no suitable method to solve the above problems. Obviously, it is a problem that relevant industry players are eager to solve.

Abstract

The invention relates to a method for manufacturing a pressure vessel by utilization of metal nickel electrotyping, comprising preparation of a mandrel, manufacturing and copying, and demoulding, wherein, the compositions of an electrodeposition cell solution used in the step of manufacturing and copying are 60 to 120 weight portions of nickel sulfamic acid, 10 to 40 weight portions of boric acid, 2 to 6 weight portions of sulfamic acid, 2 to 6 weight portions of nickel carbonate, 2 to 6 weight portions of nickel chlorite and 1,000 weight portions of water; and the operating conditions of the electrodeposition cell solution are as follows: the pH value is between 3.50 and 4.80; the operating temperature is between 45 and 70 DEG C; the operating voltage is between 12 and 15 volts direct current; and the current density is between 0.5 and 6.0 amperes per square decimeter. The method is simple and convenient in manufacturing, does not require a plurality of devices, saves the manufacturing cost, and then is more suitable for practical use.

Description

technical field [0001] The invention relates to a method for manufacturing a container, in particular to a method for manufacturing a pressure container. Background technique [0002] In daily life, people often use some containers that can withstand a certain pressure. Such as the air tank of the air rifle used in shooting sports. This kind of pressure vessel is made of a metal inner tank by deep drawing and drawing of a metal material sheet. Then the canned food is processed on the inner tank, and then the outer surface of the inner tank is tightly wound with a fiber thermosetting resin composite material to increase the pressure resistance of the inner tank. [0003] The key to the manufacture of this container is the deep drawing and stretching of the inner container. The process of deep drawing and drawing is a gradual process, and the processing amount of each deep drawing and drawing should not be too large, otherwise it is easy to pull and tear. At the same time,...
