Problems solved by technology

[0003] The main defects and deficiencies of the above-mentioned processing method: processing by the first method, the material waste is serious, the cost is high, the cutting allowance is large, the cutting force and cutting heat are large, the deformation of the part after processing is large, the surface quality is poor, and the dimensional accuracy is not easy to guarantee. , and it is inconvenient to position and clamp
Through the second method of processing, the material waste is serious, the cost is high, the wire cutting cost is high, the processing cost is high, and the subsequent positioning and clamping are inconvenient

Embodiment 1

[0037] Using the above scheme, processing such as figure 1 Hollow frame parts shown. The actual operation mainly includes the following steps:

[0038] 1. Casting process: ZL101-T6 cast aluminum alloy is selected and cast into such figure 2 The flat annular blank shown has the same shape as figure 1 The parts shown have the same shape, and the blank size is 1mm-2mm larger than the part size on one side. The middle part of the blank is hollowed out, and cross-shaped ribs 2 are evenly arranged in the hollowed-out inner cavity. The cross-shaped ribs are flush with the bottom surface of the blank, and the thickness of the cross-shaped ribs is 1 / 3-1 / 2 of the thickness of the blank. Parallel and perpendicular to the two flat sides of the blank.

[0039] 2. Turning processing: Symmetrical turning processing of both ends of the surface, so that the removal allowance of the two ends of the surface is consistent, and the thickness after processing is consistent with the total thick...

Abstract

The invention provides a hollow frame part machining method. Ribs are machined in a hollow frame of the part firstly, then the part is cut, and the ribs are cut off after cutting is completed. According to the hollow frame part machining method provided by the invention, part machining of the hollow-frame part can be completed efficiently in a high-quality mode, the product surface quality is high, the size precision is stable and reliable, the product consistency is good, the technological process is reasonable and compact, the production efficiency is high, the convenience in clamping is realized, the operation is conducted conveniently and quickly, the labor intensity is low, and the material cost and the machining cost are saved.

Description

technical field [0001] The invention relates to a processing method for a hollow frame part. Background technique [0002] Hollow frame parts have the advantages of complex shape, thin wall, light weight, material saving, compact structure, etc., and have been widely used in aviation, aerospace and other fields. Such as figure 1 The hollow frame part shown is flat and ring-shaped, with a maximum external dimension of 400mm. Its main body is in the shape of a hollow flat ring, with a thin wall and a wall thickness of 5mm. The middle position of the side extends outward to form a flange consistent with the shape of the main body. In addition, the circumference is evenly provided with bosses, and there are mounting holes on the bosses. The side of the boss is aligned with the side of the main body, and the flange is embedded in the middle of the boss. Such parts have poor rigidity during processing, inconvenient clamping, variability, size and position accuracy are not easy ...
