What factors should we pay attention to when choosing valve blanks when we are machining?The following will introduce how to choose the valve blank, fromThe size of the production program, the conditions for the production of blanks,Organization and performance requirements of part materials,Part structure shape and overall dimensionsFour aspects are explained:
one,The size of the production program:The larger the production program of the parts, the better the economic effect of using a high-precision and high-efficiency blank manufacturing method.
two,Conditions for making blanks:The blank should be selected according to the equipment condition and technological level of the site, and the advanced blank manufacturing method should be gradually adopted considering the development prospect.
three,Organization and performance requirements of part materials:The material of the part specified on the design drawing generally determines the type of blank. For example, if the part material is cast iron, the casting method must be used to make the blank. For steel parts, the mechanical property requirements of the material should be considered when selecting the blank. For example, parts for manufacturing high-pressure valves should generally use forgings or welded parts as much as possible to ensure that the materials have good mechanical properties.
4. Part structure shape and overall dimensions:The structural shape of the part is an important factor affecting the selection of the blank. For example, the valve body with complex structural shape should try to use castings. Sand casting can be used for larger valve bodies; investment casting is used for smaller valve bodies.
The above four points are the content of how to choose valve blanks to share with you today, from the size of the production program, the conditions of blank manufacturing,Organization and performance requirements of part materials,Part structure shape and overall dimensionsto explain.
