Problems solved by technology
[0003] The first category: It is made of multiple metal plates joined together. The cost of this type of metal container is low, but there are joint gaps on the surface of the metal container, which seriously affects the appearance of the product, and it is necessary to make joints on the joint gap. Sealing treatment, such as: soldering or applying sealant, etc., but the leakage and pollution of the contents are often caused by the problem of sealing quality
[0004] The second type: It is formed by extruding a metal block with an extrusion machine and an extrusion die, or stamped and stretched by a metal sheet, although there is no joint gap on the surface of this type of metal container to prevent leakage and pollution of the contents The effect is good, but when the metal container is closed, it is usually processed by a spinning machine, which requires high operating skills for the workers and high labor intensity, and the transition arc on the container mouth is not smooth enough, and often requires Polish the transitional arc, which greatly reduces the production efficiency of the product and increases the production cost

Embodiment Construction
[0014] A kind of manufacture method of aluminum pot, its process step is as follows:
[0015] (1) First, the aluminum metal is processed into a cylindrical pot body with a bottom wall by using extrusion technology or stretching technology, and then the edge is trimmed at the opening of the cylindrical pot body to ensure that the height of the cylindrical pot body is uniform;
[0016] The steps of using stamping and stretching technology to make a cylindrical pot body are as follows: first, punch out a suitable round aluminum sheet according to the size of the aluminum pot to be produced, and then perform one or more stamping and drawing of the round aluminum sheet according to the height of the aluminum pot. Stretch to become a cylindrical pot body.
[0017] The steps of using extrusion technology to make a cylindrical pot body are as follows: select an aluminum block of a suitable size according to the size of the aluminum pot to be produced, and then preheat the aluminum blo...

The metal container making process includes the following steps: the first extruding or stretching metal material into cylinder, cutting edge in the cylinder openings, gradually reducing mouth with several forming molds of gradually reduced inner diameters, cutting the mouth edge, making thread fitting that in the container cover in the mouth, surface cleaning, stoving and surface polishing, spraying paint to the inner surface and stoving, and spraying paint to the outer surface and stoving. Thus made metal container has round transition arc in the mouth and stable product quality.
Description
technical field [0001] The invention relates to a manufacturing method of a metal container. Background technique [0002] The current manufacturing methods of metal containers are generally divided into two categories: [0003] The first category: It is made of multiple metal plates joined together. The cost of this type of metal container is low, but there are joint gaps on the surface of the metal container, which seriously affects the appearance of the product, and it is necessary to make joints on the joint gap. Sealing treatment, such as: soldering or coating sealant, etc., but the leakage and pollution of the contents are often caused by the problem of sealing quality. [0004] The second type: It is formed by extruding a metal block with an extrusion machine and an extrusion die, or stamped and stretched by a metal sheet, although there is no joint gap on the surface of this type of metal container to prevent leakage and pollution of the contents The effect is good...
