Embodiment Construction

[0029] Examples of traditional crafts, such as figure 1 , 2 , 3:

[0030] In the field of aerospace, it is often necessary to machine die forging single-sided thin-walled structural beam parts, typical structures such as figure 1 Shown:

[0031] The part material is 7B04 T6 (MD), the size is 1625mm×140 mm×δ52 mm, and the part width gradually changes from 140 mm to 2mm.

[0032] According to the existing mechanical processing scheme, the steps are:

[0033] (1) Roughly machine planes A, D, and C first, with a margin of 2mm on one side, such as figure 2 shown;

[0034] (2) The processing planes A, B, C, and D are in place, such as image 3 shown;

[0035] (3) The inner shape of the part, the height of the web and the ribs are in place.

[0036] After processing, the parts will be twisted and warped, the deformation amount is 5-9mm, and the shape needs to be corrected. Due to the large amount of deformation, the parts are prone to cracks and scrapped during the calibrat...

Abstract

The invention relates to a die forging single-sided thin-walled structure beam part variation compensation machining method, and belongs to the field of machining methods. After die forging single-sided thin-walled structure beam parts are machined by the compensation machining method, the warping deformation amount of the parts is controlled within 3mm, all the parts are qualified after slight calibration, and the quality of the parts is effectively ensured. Machining of the die forging single-sided thin-walled structure beam parts is popularized in factories, and the problem of warping deformation of the parts is effectively solved.

Description

technical field [0001] The invention relates to a compensation method processing method for single-sided thin-walled structural beam parts of die forgings, belonging to the field of mechanical processing methods. Background technique [0002] In the field of aerospace, it is often necessary to machine die forging single-sided thin-walled structural beam parts; for example, the part material is 7B04 T6 (MD), the size is 1625mm×140 mm×δ52 mm, and the part width gradually changes from 140 mm to 2mm. [0003] According to the existing mechanical processing scheme, the steps are: [0004] (1) Roughly machine planes A, D, and C first, with a margin of 2mm on one side; [0005] (2) The processing planes A, B, C, and D are in place; [0006] (3) The inner shape of the part, the height of the web and the ribs are in place. [0007] After processing, the parts will be twisted and warped, the deformation amount is 5-9mm, and the shape needs to be corrected. Due to the large amount...
