Enamel cutting tools for enamelled electrical heating joints

Abstract

The invention discloses a porcelain glaze cutting tool used for a porcelain glaze electric-heating joint, and the porcelain glaze cutting tool is used for precisely controlling a porcelain glaze cutting thickness of the porcelain glaze electric-heating joint so as to improve corrosion resistance of the porcelain glaze electric-heating joint and prolong the service life of the porcelain glaze electric-heating joint. The porcelain glaze electric-heating joint comprises a straight barrel part and a flaring part, wherein one end, away from the flaring part, of the straight barrel part is equippedwith a ring-shaped limiting groove; the porcelain glaze cutting tool comprises a rotary handle, a limiting rotary disc and a rotary cutter which are sequentially connected, and have rotary axes superposed, wherein the limiting rotary disc can be limited in the ring-shaped limiting groove; the rotary cutter comprises a first cutting part which corresponds to the inner wall of the straight barrel part, and a second cutting part which corresponds to the inner wall of the flaring part through the straight barrel part.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an enamel cutting tool used for enamel electric heating joints. Background technique [0002] As water heaters are more and more accepted by users, users also pay more and more attention to the service life of water heaters. The corrosion resistance of the inner tank of water heaters is an important indicator that determines the service life of water heaters. [0003] Electric heating enamel liner, as a new type of water heater liner, has good corrosion resistance and has always attracted the attention of the industry. The electric heating type enamel liner is usually connected with an enamel electric heating joint through which a power supply heating rod extends. The enamel electric heating joint includes a straight part and a flared part, and the flared part is connected and communicated with the enamel liner. Due to the special structural design of the enamel electric h...

AI Technical Summary

Problems solved by technology

Due to the special structural design of the enamel electric heating joint, when the inner wall of the enamel electric heating joint is covered with enamel, the thickness of the enamel is not easy to control. If the enamel is too thick, it will cause difficulty in assembly. If the enamel is too thin, it will easily leak out due to corrosion.

At present, the enamel cutting of enamel electric heating joints is mainly performed with a small knife, which not only has low accuracy, but also has low cutting efficiency.
