Embodiment Construction

[0029] The present invention aims to provide a molding process for beer can screw caps. The process uses film-coated metal as raw material. According to the characteristics of the material, after a large number of tests, a method suitable for preparing beer can screw caps with film-coated metal as raw material is obtained. Cover production process.

[0030] A kind of beer can screw cap molding process of the present invention, comprises:

[0031] Step 1 101: Stamping and stretching the sheared blank into a beer can screw cap blank;

[0032] In step one 101, the upper notch die and the lower notch die cooperate with each other to cut the material into the required size of the blank, and then punch and draw the cut blank through the upper forming die and the lower forming die of the basic cover stamping machine Stretch into beer can screw cap blank.

[0033] The shape of the beer can screw cap blank obtained by stretching is a hollow shallow disk with one end open.

Abstract

The invention aims to provide a molding process of a beer can screw cap. In the process, a laminated film is used as a raw material, and according to the characteristics of the material, through a lotof experiments, a production process for preparing the beer can screw cap from the laminated film as the raw material can be obtained. The molding process adopting the technical scheme comprises thefollowing steps of 1, stretching a sheared blank into a beer can screw cap blank; 2, stretching the beer can screw cap blank for multiple times to form a semi-finished product; 3, trimming the semi-finished product and punching; 4, preliminarily curling the edge contour of the bottom of the semi-finished product and the circumferential edge of a punched hole; and 5, curling the edge contour of thebottom of the semi-finished product and the circumferential edge of the punched hole; and 6, flattening the curled parts, and tapping the surfaces, thereby obtaining the beer can screw cap.

Description

technical field [0001] The invention belongs to the technical field of can lid processing, and in particular relates to a forming process of a beer can screw cap. Background technique [0002] At present, compared with other materials, metal containers have stronger temperature and pressure bearing capacity and are easier to transport. Therefore, in the field of beverage, beer and food packaging, the use of metal containers has broad prospects. [0003] But metal containers are susceptible to corrosion, which affects food safety. With the rapid development of the chemical industry, coatings have become a new method to protect metal containers from external corrosion. Various coatings such as epoxy phenolic, epoxy amino, imitation porcelain coatings, aluminum paste coatings, and water-based coatings are widely used on metal containers. , while avoiding metal corrosion, it also brings the risk of chemical substances migrating to food. Contents of the invention [0004] The...
