Problems solved by technology

Cups such as glass cups and ceramic cups have large mouths and sufficient strength. However, glass cups and ceramic cups are heavy and suitable for home use and are not easy to carry. They are also not suitable for mass production and transportation.
Disposable paper cups, plastic cups and other cups also have larger mouths, but they are light in weight, but not strong enough and not easy to carry

Embodiment 1

[0025] A production process of a stepped metal cup, which comprises the following steps:

[0026] 1) The aluminum coil material is stretched into a cylindrical prefabricated cup, and the prefabricated cup is stretched at least once to form a cylindrical basic cup;

[0027] 2) stamping and stretching at least once to punch out the cup-shaped step, and at least one extrusion to expand the cup-shaped step to obtain a stepped cup, such as figure 1 shown.

Embodiment 2

[0029] like figure 2 Shown, a kind of production technology of stepped metal cup, it comprises the following steps:

[0030] 1) The filmless aluminum coil material is stretched into a cylindrical prefabricated cup, and the prefabricated cup is punched and stretched at least once to form a cylindrical basic cup, and the basic cup is subjected to bottom forming, trimming, cleaning, printing, and primer coating , internal spray;

[0031] 2) After the basic cup-shaped internal spraying, press and stretch at least once to punch out the cup-shaped steps, and squeeze at least once to expand the cup-shaped steps to obtain a stepped cup, such as figure 1 shown.

Embodiment 3

[0033] like figure 2 Shown, a kind of production technology of stepped metal cup, it comprises the following steps:

[0034] 1) The filmless aluminum coil material is stretched into a cylindrical prefabricated cup, and the prefabricated cup is punched and stretched at least once to form a cylindrical basic cup, and the basic cup is subjected to bottom forming, trimming, cleaning, printing, and primer coating , internal spray;

[0035] 2) After the basic cup-shaped internal spraying, press and stretch at least once to punch out the cup-shaped steps, and squeeze at least once to expand the cup-shaped steps. After the steps are expanded, curl and rinse to obtain a stepped cup, such as figure 1 shown.

[0036] This process is to print first and then process the steps. Compared with the method of first processing the steps and then printing, the printed layout is larger, the pattern continuity is good, and the printing appearance is better.

Abstract

The invention discloses a production process of a step-shaped metal cup. The production process comprises the following steps of 1) stretching an aluminum coil material into a cylindrical prefabricated cup, and stretching the prefabricated cup at least once to form a cylindrical base cup; and 2) stamping and stretching for at least one time to stamp a cup-shaped step, and extruding for at least one time to expand the cup-shaped step to obtain the step-shaped cup. The production process of the step-shaped metal cup has the characteristics of larger printing layout, good pattern continuity, water resource saving and the like.

Description

technical field [0001] The invention relates to the field of metal cups. More specifically, the present invention relates to a production process of stepped metal cups. Background technique [0002] At present, most beverage containers on the market are cans and plastic bottles, both of which have the problem of small mouths. The mouths of both are not as big as the mouth of a cup, and the drinking experience is not as good as that of a cup. Cups such as glass cups and ceramic cups have large mouths and sufficient strength. However, glass cups and ceramic cups are heavy, suitable for home use and difficult to carry, and are not suitable for mass production and transportation. The mouths of cups such as disposable paper cups and plastic cups are also larger, but they are light in weight, but not strong enough and not easy to carry. Therefore, the production of a metal cup with a large mouth, sufficient strength, and easy portability has very broad market significance. Con...
