Problems solved by technology
[0007] The technical problem solved by this application is: in view of the low production efficiency, poor quality and high processing difficulty of arc-shaped castings in the prior art, this application provides a method for preparing arc-shaped castings. In the scheme provided, a cylindrical structure composed of multiple arc-shaped castings can be prepared by the arc-shaped casting processing tooling at one time, that is, multiple arc-shaped castings can be prepared at one time, which not only avoids the waste of sand core materials, but also reduces The long core-making time improves the preparation efficiency of arc-shaped castings; and in the preparation process of arc-shaped castings, by preparing a cylindrical structure composed of multiple arc-shaped castings, the deformation of arc-shaped castings is avoided, thereby improving the production efficiency. The dimensional accuracy of arc-shaped castings; also by preparing a cylindrical structure composed of multiple arc-shaped castings, there is no need to fix the arc-shaped castings through special clamping, thereby reducing the processing difficulty of arc-shaped castings

Abstract
The invention discloses a preparation method of arc-shaped castings. The method comprises the steps that the number of the arc-shaped castings needed for forming a cylinder structure is calculated according to the preset sizes of the arc-shaped castings and the preset interval between the castings; according to the preset size, shape and interval of the arc-shaped castings and the number of the arc-shaped castings, an arc-shaped casting machining tool is prepared; molding sand is injected into the arc-shaped casting machining tool and cured to obtain a sand core, an alloy solution is poured outside the sand core and cured, and the sand core and the alloy are separated to obtain a cylinder structure formed by connecting the multiple arc-shaped castings; and each circular-arc-shaped casting is divided from the cylindrical structure to obtain the multiple circular-arc-shaped castings. The technical problems that in the prior art, arc-shaped castings are low in preparation efficiency, poor in quality and large in machining difficulty are solved.
Description
technical field [0001] The present application relates to the technical field of casting processing, in particular to a method for preparing arc-shaped castings. Background technique [0002] Arc-shaped castings are a common component in the field of foundry processing technology. Arc-shaped castings are widely used in many fields. For example, parts such as air suction, dust removal, and protective covers are widely used in cotton spinning products. In the actual preparation process of arc-shaped castings, arc-shaped castings will have more processing procedures, how to quickly prepare arc-shaped castings has become a key link in the preparation process of arc-shaped castings. [0003] At present, arc-shaped castings are often processed by combined sand cores. Generally, when arc-shaped castings are processed by combined sand cores, the combined sand core is formed by combining at least two sand cores, that is, a single arc At least two sand cores are required for the prep...
