Computer aided design method for thin-wall copper alloy water meter shell casting process

Abstract

The invention relates to a computer aided design method for a thin-wall copper alloy water meter shell casting process. The computer aided design method comprises the following steps: designing parts;designing a mold; carrying out mold modeling; carryinhg out casting simulation analysis; displaying a casting simulation analysis result; optimizing a design result; carrying out process parameter optimization analysis; displaying a process parameter simulation analysis result; optimizing a process parameter result; processing a mold; carrying out production inspection; the method also comprisesstructure optimization and parameter optimization. According to the design method, the quality of the casting can be improved, the casting defects of the casting can meet the structural requirements,the trial-manufacture time of new products is greatly shortened, and the trial-manufacture cost is reduced.

Description

technical field [0001] The invention relates to a computer-aided design method for the casting process of a thin-walled copper alloy water meter shell. Background technique [0002] In recent years, under the situation of global scarcity of energy and water resources, with the continuous improvement of legal measurement, the whole society has higher and higher requirements for water measurement. As an instrument for measuring production and domestic water metering, the performance of the water meter directly affects the accuracy of water metering. The water meter case is the cavity that holds the water and the metering gear unit, so case material and performance play a crucial role. However, in the actual design and production, because the structure and size of the water meter shell will be different with the different models and uses of the water meter, in the subsequent design and production, the castings are prone to defects such as shrinkage, shrinkage and insufficient ...

Problems solved by technology

However, in the actual design and production, because the structural size of the water meter shell will be different with the different models and uses of the water meter, in the subsequent design and production, the castings are prone to defects such as shrinkage cavity, shrinkage and insufficient pouring; In addition, in actual use, the water meter shell needs to withstand a water pressure test of 5Mpa without deformation and leakage, so there are certain requirements for its strength and hardness

[0003] The traditional casting design process generally adopts the trial and error method, that is, trial production is carried out according to traditional experience, and then the quality of the water meter casing casting is analyzed, and the correct process is finally obtained through repeated improvement of the design method. Waste of time, lack of a scientific and effective design method for the casting design of the water meter shell
