Embodiment Construction

[0029] Embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0030] attached figure 1 It is the front view of a typical open part 1, the material is LC9CGS3 (free forging) aluminum alloy, the bottom surface and the web surface of the part are curved surfaces, there are many ribs in the inner cavity of the front end of the part to strengthen the part, and the tail of the part is an open structure.

[0031] The key to the processing technology of open structural parts is to find the most obvious deformation part of part 1 and effectively control the deformation amount of this part during processing. Refer to attached figure 1 It can be seen that the part with the largest deformation of the part lies in the opening of the tail of the part, and the process patch is redesigned according to the structural characteristics of the part. The patch overlapping method is to place the patch in the length direction of ...

Abstract

The invention discloses a machining technology of an open structure part. The technical problems that open parts are deformed, and surface roughness and the wall thickness size are hard to guarantee can be effectively solved. Technological patches are designed according to the structural feature of the part; the open part of the part is cut open, and threads are tapped in the positions, in an opening, of the technological patches. The machining mode of artificially connecting the open part of the part through the technological patches and a connecting steel plate is adopted, so that the percent of pass and surface machining quality of the part are improved; the reject rate of the part is remarkably reduced; manufacturing cost is saved, and machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a processing technology for open structural parts. Background technique [0002] Open structural parts have complex shapes and deep cavity structures, which are difficult to process. If the traditional aluminum alloy forging process is used, the internal stress of such parts is not fully released due to their own materials. During the processing, with the continuous release of the internal stress of the material, the open structure parts deform greatly. At the same time, due to the weak rigidity of this type of parts, the parts tremble during the processing, which makes it difficult to guarantee the smoothness and thickness of the side walls of the parts, and cannot meet the design requirements. To sum up, the traditional process of aluminum alloy forgings is not suitable for the processing of such parts. [0003] There are two major difficulties in processing su...
