Manufacturing method of bothway cylindrical part with flanges

Abstract

The invention discloses a manufacturing method of a bothway cylindrical part with flanges. The manufacturing method comprises the steps that S1, the edges of a plate material are cut so that the outer edges can form a first truncated cone and a second truncated cone which are connected to the middle portion of the plate material; S2, the side wall of the first truncated cone and the side wall of the second truncated cone are subject to spinning in the axial direction, and therefore the first truncated cone is subject to spinning in the axial direction to form a third truncated cone and a first overturning edge connected to the end of the third truncated cone, and the second truncated cone is subject to spinning in the axial direction to form a fourth truncated cone and a second overturning edge connected to the end of the fourth truncated cone; and S3, the side wall of the third truncated cone and the side wall of the fourth truncated cone are subject to spinning in the axial direction, and therefore the third truncated cone and the fourth truncated cone form a first barrel and a second barrel correspondingly, and the first overturning edge and the second overturning edge form the first flange and the second flange correspondingly. According to the embodiment, products produced through the bothway cylindrical part with the flanges are high in surface quality, even in mechanical property and low in cost.

Description

technical field [0001] The invention relates to the technical field of spinning processing, in particular to a method for manufacturing a bidirectional cylindrical part with a flange. Background technique [0002] In the related art, the two-way cylindrical parts with flanges can be manufactured by casting, forging, welding and other methods. However, the two-way cylindrical parts with flanges produced by the above-mentioned traditional processing method have the following defects: 1) The mechanical properties of the two-way cylindrical parts with flanges processed by the integral casting method are poor, and they are prone to casting Defects; 2) Due to the technological limitations of forging and forming, it is more difficult to produce two-way cylindrical parts with flanges, especially for parts with larger sizes. 3) The overall mechanical properties of the parts produced by tailor welding forming process are uneven, the welds are prone to fracture, and the production eff...

However, the bidirectional cylindrical parts with flanges produced by the above-mentioned traditional processing method have the following defects: 1) The mechanical properties of the bidirectional cylindrical parts with flanges processed by the integral casting method are poor, and they are prone to casting Defects; 2) Due to the limitations of forging and forming processes, it is more difficult to produce two-way cylindrical parts with flanges, especially for parts with larger sizes. 3) The overall mechanical properties of the parts produced by tailor welding forming process are uneven, the welds are prone to fracture, and the production efficiency is low;

[0005] 2) When using the second processing method to produce parts, during the forming shoveling process, the upper cylinder wall forms a process similar to metal stacking, the interaction between metal grains is damaged to a certain extent, the mechanical properties are reduced, and the formed The thickness of the cylinder wall is seriously uneven, and there is a problem of thin bottom thickness; during the thinning spinning process, the contact area between the cylinder wall and the mandrel is relatively large, the forming force increases sharply, and the requirements for equipment are high

[0006] In addition, the above two spinning forming methods are usually only used for the processing of cylindrical parts, and it is still difficult to process bidirectional cylindrical parts with flanges
