Problems solved by technology

[0002] The bottle caps used for beverages in the market are generally plastic, and the bottle caps of cups commonly used by people are usually wrapped with plastic or glass. There are very few pure metals, but glass caps are easy to damage. It will be broken, so the bottle will be wasted, and the metal-wrapped plastic bottle cap is easy to deform, resulting in poor sealing performance in later use, and easy to cause safety hazards such as burns; and some ordinary metal bottle caps due to production process problems, After a long time of use, it is easy to be corroded, easy to rust, and the service life is very short

Embodiment Construction

[0016] The following is a detailed description of the invention, but the invention can be implemented in many different ways as defined and covered by the claims.

[0017] The invention discloses a tinplate bottle cap manufacturing process, comprising the following steps:

[0018] (1) Drawing: First, calculate the amount of material required for the bottle cap according to the size of the bottle cap to be made, and then actually draw the drawing;

[0019] (2) Basic material processing: purchase and select tinplate plates with a thickness of 0.25-0.3mm, cut the tinplate into rectangular blocks according to the drawings, and the margin deviation is ±0.05mm;

[0020] (3) Rust treatment: put the cut tinplate rectangular block into the prepared 5% dilute hydrochloric acid solution and soak for 3 minutes, take it out, and polish it with a grinding wheel. After the rectangular block is washed in pure water, it is dried naturally;

[0021] (4), bottle cap stamping: punch the dried r...

Abstract

The invention discloses a making technology for tinplate bottle caps. The making technology comprises the steps of drawing, basic material treatment, rust treatment, bottle cap stamping, bottle cap forming, formed bottle cap embossing, waxing, surface treatment and the like. According to the making technology, treatment of rust removal and rust corrosion prevention is conducted on the bottle caps obtained through simple working procedures, so that the bottle caps are not liable to corrosion and rusting when in use, and the service life is greatly prolonged; the bottle caps are not liable to damage and deformation; and the material is cheap tinplate, so that investment is low.

Description

technical field [0001] The invention relates to the field of bottle cap manufacture, in particular to a tinplate bottle cap manufacturing process. Background technique [0002] The bottle caps used for beverages in the market are generally plastic, and the bottle caps of cups commonly used by people are usually wrapped with plastic or glass. There are very few pure metals, but glass caps are easy to damage. It will be broken, so the bottle will be wasted, and the metal-wrapped plastic bottle cap is easy to deform, resulting in poor sealing performance in later use, and easy to cause safety hazards such as burns; and some ordinary metal bottle caps due to production process problems, After a long time of use, it is easy to be corroded, easy to rust, and has a short service life. Contents of the invention [0003] The object of the present invention is to provide a metal product with a long service life, which is not easy to damage and prevents rust. [0004] In order to s...
