Example Embodiment

[0018] The processing technology of an open structure part of the present invention is characterized in that it comprises the following steps:

[0019] (1) Rough machining: rough machining the front and back of the part, remove the blank material of the main body of the part, and process the contour of the part. After the rough machining, the part has a process allowance of 3mm, which is used for material removal during semi-finishing and finishing;

[0020] (2) Heat treatment of parts after rough machining;

[0021] (3) Cut the open structure part of the part: After the heat treatment of the part is completed, the open structure part of the part is cut, the purpose is to create a stress relief area, and guide the internal stress of the part to release in the cut area;

[0022] (4) Tap the threaded hole on the process patch at the opening for use when installing and fixing the connecting steel plate, making preparations for the connecting steel plate;

[0023] (5) Natural aging: natural...

Abstract

The invention discloses a machining technique for a component of an open-type structure. The machining technique is characterized in that the machining technique comprises the following steps that (1)rough machining is conducted, specifically, the front face and the back face of the component are roughly machined, a main body blank material of the component is removed, the component outline is machined, the technical allowance of the component is reserved by 3 mm after rough machining for material removing during semi-finish machining and finish machining; (2) the roughly-machined component is subjected to heat treatment; and (3) the open-type structure part of the component is cut up, specifically, after heat treatment of the component is completed, the open-type structure part of the component is cut up in order that an area for stress releasing is manufactured, and stress inside the component is guided to be released in the cut-up area. The machining technique has the following advantages that the technical problems that the open part of the component is deformed, and the surface roughness and the wall thickness size are hard to guarantee can be effectively solved, the qualified rate of the component is increased, the surface machining quality of the component is improved, the rejection rate and the defective rate of the component are decreased obviously, the manufacturingcost is saved, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of transmission machinery, 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. Contents of the invention [0003] In order to solve th...
