Two-half type splicing water meter casing and processing method thereof

Abstract

The invention relates to a two-half type splicing water meter casing, which comprises a left cavity, a right cavity and a water separation plate, wherein the left cavity and the right cavity are mutually matched; each of the left cavity and the right cavity comprises a middle case, a water inlet end and a water outlet end which are integrally formed; a water separation plate positioning grooves are formed in the inner walls of the left cavity and the right cavity; when the left cavity, the right cavity and the water separation plate are assembled; the edges of the water separation plate are totally clamped in the positioning grooves of the water separation plate, so that the water separation plate is arranged in the casing in a sealed way. The invention also relates to a processing methodof the water meter casing. The method also comprises the steps of assembly punching shaping, blank assembling, welding and shaping and numerical control machine processing. The water separation platepositioning groove is formed in the left and right cavities; during the assembly, a braze welding material welding process is used as an auxiliary process to solve the problems of casing assembly positioning and sealing. The two-half type splicing water meter casing has the advantages that no pollution is caused during the processing; the process is simple and convenient, and achieves the environment-friendly effects; the production efficiency is high; the period is short; the product qualification rate is obviously improved. Meanwhile, the product surface is smooth and like a mirror surface;the appearance is novel and bright.

Description

technical field [0001] The invention relates to a two-half assembled water meter shell and a processing method thereof. Background technique [0002] At present, the forming process of the water meter shell is limited to investment casting and sand casting of stainless steel materials. There are many process links, complex process and long period, serious production environmental pollution, and casting rough defects are prone to occur, such as pores, shrinkage cavities, shrinkage Loose, sunken, multi-material, black spots, pockmarks, cracks, etc., the gaps are prone to corrosion, affecting the appearance and service life. At the same time, due to the limitations of the casting process, the fluidity of the stainless steel material in the liquid state is relatively poor. In order to prevent cold shut, insufficient pouring and shrinkage cavity of castings, large riser feeding is required in the process. At the same time, in order to reduce the insufficient pouring of thin-wal...

AI Technical Summary

Problems solved by technology

At the same time, in order to reduce the insufficient pouring of thin-walled castings, the surface wall is relatively thick, resulting in bulky products, so the rough yield of castings is low

In summary, the production cost of the existing process is relatively high, and the surface roughness of the product appearance is relatively poor, which directly affects the appearance and quality of the water meter product
