Problems solved by technology

[0004] Because the material of this type of shell is aluminum alloy profile, the profile is easy to deform, and because multiple positioning and clamping are required in the processing process, the processing time is correspondingly increased. The size is out of tolerance, resulting in product scrapping

Embodiment 1

[0033] Example 1 is as Figures 1 to 4 As shown in the figure, a processing method of a shell, the specific steps are as follows:

[0034] 1) Material preparation: Prepare LY12-CZ aluminum profile according to GBn222-1984, and the profile size L9 has been formed; preparation time: 30 minutes, processing time: 30 seconds.

[0035] 2) sawing machine cutting: the figure 1 Milling from L2 to (L2+1)mm, this process can process multiple profiles at a time; preparation time: 30 minutes, processing time: 10 seconds.

[0036] 3) Counting milling: Clamping L9, milling L2 and 4-R5 size; preparation time: 120 minutes, single piece processing time: 120 seconds.

[0037] 4) Fitter: remove the burr after milling; preparation time: 30 minutes, processing time: 60 seconds.

[0038] 5) Correction: Align the semi-finished product 6 with the shape of the product to the via hole 7, insert part of the semi-finished product 6 into the via hole 7, set the spring 2 on the positioning pin 3, align t...

Abstract

The present application discloses a method for processing a shell in the technical field of aerospace manufacturing, including material preparation, preparing aluminum profiles according to product standards; milling worker: milling out the shape of the product; calibration: using a straightening die device to correct the product, and the straightening die device includes: Straightening die and upper platen. The middle of the straightening die has a through hole that is consistent with the shape and size of the product. The bottom of the upper platen is provided with a bump for inserting the through hole. Insert the semi-finished product that has been milled out of the product shape into the through hole. In the middle, align the bumps of the upper pressure plate with the semi-finished product and press down, so that the semi-finished product comes out from the other end of the straightening die through the through hole. The invention adopts the straightening die device to correct and mill the semi-finished product of the product shape. After straightening the semi-finished product, the positioning reference can be effectively guaranteed. Finally, the numerical control machine tool is used for milling the hole, which reduces the preparation time for multiple clampings, and greatly reduces the time required for multiple clamping. The production cost is reduced, and the qualified rate of the finished product is improved at the same time.

Description

technical field [0001] The invention belongs to the technical field of aerospace manufacturing, relates to a processing method of a casing and a straightening die device thereof, and specifically relates to a processing method for products with similar structures such as flap locks and a straightening method for the processing method. mold device. Background technique [0002] With the development of my country's aviation industry, the products used in aircraft and aircraft engines tend to be high-precision and sophisticated. These products require high precision and good quality consistency. [0003] For example, shell products such as flap locks are often used for connection and installation parts such as aircraft fuselage structures, hatch doors, and bottom plates. The products are used in a large amount on aircraft, and their processing requirements are as follows: figure 1 As shown, the specific processing methods include: 1. Material preparation: prepare LY12-CZ alumi...
