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 processing: ZL101-T6 cast aluminum alloy is selected, and the casting is as follows 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 hollow cavity. The cross-shaped ribs are flush with the bottom surface of the blank. 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: Symmetrically turning both ends, so that the removal allowance of both ends is consistent, and the thickness after processing is consistent with the total thickness of the part.

[0040] 2.1. Car end face: Put the fi...

Abstract

The invention provides a processing method for a hollow frame part. Ribs are firstly processed in the hollow frame of the part, and then the parts are cut and processed, and the ribs are cut off after the cutting process is completed. The invention can complete the processing of hollow frame parts with high efficiency and high quality, the product surface quality is high, the dimensional accuracy is stable and reliable, the product consistency is good, and the process flow is reasonable and compact, the production efficiency is high, the clamping is convenient, the operation is convenient, and the labor intensity is low , saving material cost and processing cost.

Description

technical field [0001] The invention relates to a processing method for hollow frame parts. 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. like figure 1 The hollow frame part shown is in the shape of a flat ring with a maximum external dimension of 400mm. Its main body is a hollow flat annular cylindrical shape with a thin wall and a wall thickness of 5mm. The middle position of the side surface extends outward to form a flange consistent with the main body shape. 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, difficulty in ensuring size and position accuracy, and poor product consistency. At present, there are two main ways to process such parts:...
