Problems solved by technology

The disadvantages are: the correction method is to remove the deformation by applying external stress. This method seriously affects the internal material structure of the part. At the same time, cracks and uneven stress often occur during the correction process, which seriously affects the product quality of the part.

Embodiment Construction

[0017] A deformation control method in the processing of double-sided multi-rib structural parts, comprising the following steps:

[0018] 1) Use tooling to clamp the part blank;

[0019] 2) Milling single-sided datum can see the inner layer of new metal;

[0020] 3) Turn the part over, and clamp the part with vacuum adsorption and external tooling;

[0021] 4) Process the web and sides on the front side, leave a small margin or directly process them in place, and do not process the height of the ribs;

[0022] 5) Remove vacuum adsorption and external tooling, such as figure 1 As shown, the deformation of the upper surface part is removed in the natural state 1;

[0023] 6) After turning over, use vacuum adsorption and external tooling to clamp the part again, and carry out rough machining and finishing machining on the reverse side until it reaches the size of the part;

[0024] 7) Turn over again, use vacuum adsorption and external tooling to clamp the part, mill the fro...

Abstract

The invention relates to a deformation controlling method for machining a double-side multi-rib structural part. The method comprises the following steps of: 1) clamping a part blank by adopting a tool; 2) milling a single side reference till a new metal inner layer appears; 3) turning over the part, and clamping the part by using vacuum adsorption and an external tool; 4) machining a web plate and a lateral surface on the front side, and reserving low allowance or directly machining in place, wherein ribs are not machined in height; 5) removing the vacuum adsorption and the external tool, and removing the deformation of the upper surface part in a natural state; 6) turning over and then clamping the part by using the vacuum adsorption and the external tool again, and performing rough machining and finish machining on the reverse side sequentially till the size of the part is achieved; and 7) turning over again, clamping the part by using the vacuum adsorption and the external tool, milling the ribs on the front side until the height is appropriate, and performing finish machining till the size of the part is achieved. According to the method, the deformation of the part is controlled by adopting an internal stress counteraction method in the part machining process, so that the machining period is shortened, and the quality of the part is improved.

Description

technical field [0001] The invention relates to a deformation control method in the processing of double-sided multi-rib structural parts, which belongs to the field of mechanical processing. Background technique [0002] There are mainly two types of deformation process methods in the original control of double-sided multi-reinforced structural parts processing: [0003] 1) The method of multiple turning over is: after double-sided milling benchmark, through rough machining-turning-rough machining-turning-semi-finishing-turning-semi-finishing-turning-finishing-turning- Finishing, in this way, the method of repeatedly turning over to remove the allowance removes the deformation of the part. After each turning over, the external clamping force is used to offset the deformation of the part. Its disadvantages are: the biggest disadvantage of multiple turning over is that the processing cycle is too long, the labor intensity of workers is too high, and the processing benchmark ...
