Embodiment Construction

[0012] On the flat ground far away from the human world, spread the carbon steel plate on the ground, and then lay the inner stainless steel plate, put the explosive on the inner stainless steel plate, ignite the explosive, and generate heat and shock waves through the explosive explosion, so that the carbon steel plate and the inner The layers of stainless steel plates are welded and fused together to form a composite plate.

[0013] Cut the prepared composite board into a round body.

[0014] A hemispherical hollow mold is made of metal or impact-resistant cement, the round body is placed in the upper mouth of the hollow mold, and then the explosive is laid on the round body of the composite plate, and then the hollow mold is closed with a metal plate to ignite the explosive. Under the explosive action of the explosive, the circular body of the composite plate is heated and compressed, deforms along the shape of the cavity of the hollow mold, and becomes a hemisphere.

Abstract

The invention provides a method for molding a spherical tank through explosion. A composite board is manufactured in a welded manner through explosion, and is then cut into round bodies, the round bodies are placed into a hollow die, and an upper opening is closed; semi-spherical tank bodies are molded through explosion, and the two semi-spherical tank bodies are combined together; and the spherical tank is manufactured through welding lines in a welded manner. The spherical tank is manufactured with the method, and has the beneficial effects of being rapid in molding, saving working hours and fewer in welding lines; and the spherical tank is regular in shape and high in strength. The method is suitable for being applied to manufacturing of the spherical tank.

Description

Technical field [0001] The invention proposes a processing method in the field of metal processing, specifically a method of explosively forming a spherical tank body. Background technique [0002] Before the present invention was proposed, the spherical tank body was usually explosively welded by bimetallic plates, then cut, formed in sections by a press, and then welded into the spherical tank body. The disadvantage is that the processing process is cumbersome, the shape is difficult to ensure regularity, and the welding is difficult. Summary of the invention [0003] In order to realize the explosive forming of the spherical tank body, the present invention proposes a method for explosively forming the spherical tank body. In this method, a composite board is made by explosive welding, and then the sheet-like composite board is placed in the spherical tank forming mold, the upper mouth is closed, explosives are filled in the closed mouth and the composite board, the explosives...
