Description

Technical Field

[0001] This invention relates to a part processing method, specifically a processing method for a thin-walled cabin part and the thin-walled cabin part itself. Background Technology

[0002] The cabin parts are thin-walled cabin-type parts with irregular external features. Currently, the traditional method for processing such parts is to use round tube blanks for machining. Machining with round tube blanks removes a lot of raw materials, resulting in serious waste, high internal stress in the parts, poor dimensional stability, easy deformation, low yield of finished products, and a large amount of material removal, long process, and low efficiency.

[0003] Therefore, there is an urgent need to provide a processing method for thin-walled cabin parts to solve problems such as easy deformation, low yield, excessive material removal, and long processing steps when processing tubular blank parts. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention provides the following technical solution:

[0005] The first aspect of this application provides a method for processing a thin-walled cabin part, the method comprising:

[0006] A continuous extrusion blank is provided having an irregular portion adapted to the irregular feature, so that the blank has a profile similar to that of the cabin-like thin-walled part;

[0007] The blank is milled to remove excess material so that the milled blank has the same dimensions as the thin-walled cabin-like part.

[0008] Preferably, the cabin-type thin-walled part includes a main body, which is in the shape of a thin-walled cylindrical tube;

[0009] The irregular features include: two irregular protrusions and four bosses. The two irregular protrusions are symmetrically arranged about the first central axis of the cabin-like thin-walled part. Two of the four bosses are symmetrically arranged about the first central axis. The four bosses are symmetrically arranged about the center of the second central axis.

[0010] The first central axis extends radially along the body, and the second central axis extends axially along the body.

[0011] Preferably, the minimum wall thickness of the main body of the cabin-type thin-walled part is 2mm, and the minimum machining tolerance is 0.075.

[0012] Preferably, the irregular portion includes: two first irregular portions and four second irregular portions;

[0013] The two first irregularly shaped portions are arranged in the same way as the two irregularly shaped protrusions and have similar outlines, and are used for milling to form the irregularly shaped protrusions. The four second irregularly shaped portions are arranged in the same way as the four bosses and have similar outlines, and are used for milling to form the bosses.

[0014] Preferably, the blank further includes a process boss portion, which is located on the side of the blank opposite to the two first irregular portions, to prevent uneven material flow.

[0015] Preferably, the billet is formed by an extrusion process.

[0016] The second aspect of this application provides a thin-walled cabin part, which is manufactured using the aforementioned thin-walled cabin part manufacturing method. The thin-walled cabin part includes a cabin-type thin-walled part with irregular shape features.

[0017] Beneficial effects

[0018] This invention provides a processing method for thin-walled cabin parts and the thin-walled cabin parts themselves, which have the following advantages: High-precision continuous extrusion blanks with irregularly shaped portions are used instead of round tubular blanks. These blanks are manufactured using a continuous profile extrusion process and have a contour similar to that of the cabin-type thin-walled parts. The dimensions of the finished parts, i.e., the cabin-type thin-walled parts, can be achieved through a small amount of subsequent milling. This processing method reduces the amount of material removed during part processing, effectively reducing internal stress during part processing. The finished parts have stable dimensions, improved yield, fewer processing steps, significantly improved processing efficiency, and the blank weight can be reduced by more than 50%, thus reducing energy consumption.

[0024] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0026] The cabin parts are thin-walled cabin parts with irregular external features. Currently, the traditional method for processing such parts is to use round tube blanks for machining. However, there are problems such as the removal of a lot of raw materials and serious waste when using round tube blanks for machining. In addition, the internal stress of the parts is large, the dimensional stability is poor, and they are easy to deform. The yield of finished products is low, and the amount of material removed is large, the process is long and the efficiency is low.

[0027] Example 1

[0028] Reference Appendix Figure 1 - Appendix Figure 4 To address the aforementioned problems, Embodiment 1 of the present invention provides a method for processing thin-walled cabin parts, used to process cabin-type thin-walled parts 2 with irregular shapes. The method includes:

[0029] Step 101: Provide a continuous extrusion blank 1 with an irregularly shaped portion adapted to the irregular features, so that the blank 1 has a contour similar to the cabin-like thin-walled part 2.

[0030] Specifically, the cabin-like thin-walled part 2 ultimately obtained by this method includes a main body, which is in the shape of a thin-walled cylindrical tube. Its irregular features include two irregular protrusions 21 and four bosses 22. The two irregular protrusions 21 are symmetrically arranged about a first central axis of the cabin-like thin-walled part 2. Two of the four bosses 22 are symmetrically arranged about the first central axis in pairs, and the four bosses 22 are symmetrically arranged about a second central axis. Here, the first central axis extends radially along the main body, and the second central axis extends axially along the main body. To obtain such a cabin-like thin-walled part 2, in this embodiment of the invention, a continuous extrusion blank 1 is first provided in step 101. This blank 1 is a precision blank 1 manufactured by an extrusion process, and the blank 1 has irregularly shaped portions corresponding to and adapted to the aforementioned irregular features, so that the blank 1 has a contour similar to that of the cabin-like thin-walled part 2, with dimensions slightly larger than the cabin body. For thin-walled parts 2, in step 101, based on processing experience and the finished part drawing, a certain processing allowance is reserved for the finished part, i.e., the cabin-type thin-walled part 2. The traditional tube blank 1 is designed as a precision blank 1 that closely matches the outer contour of the finished part, i.e., the cabin-type thin-walled part 2, reducing subsequent machining processes and improving processing efficiency. It has been verified that the blank 1 provided in step 101 of this embodiment can reduce weight by more than 50% compared to the traditional tube blank, which can effectively reduce energy consumption. The irregular part of the blank 1 includes: two first irregular parts 11 and four second irregular parts 12. The two first irregular parts 11 are arranged in the same way as the two irregular protrusions 21 and have similar contours. They are used for milling to form irregular protrusions 21. The four second irregular parts 12 are arranged in the same way as the four bosses 22 and have similar contours. They are used for milling to form bosses 22.

[0031] Step 102: Mill the blank 1 to remove the excess part of the blank 1 so that the milled blank 1 has the same size as the cabin-type thin-walled part 2.

[0032] Specifically, since the overall outline of the blank 1 provided in step 101 of this embodiment is similar to the outline of the finished part, namely the cabin-type thin-walled part 2, in step 102, the size of the finished part, namely the cabin-type thin-walled part 2, can be achieved by a small amount of milling. Moreover, the material cutting amount and material removal during the processing are small, the processing stress is small, and the size of the finished part, namely the cabin-type thin-walled part 2, is stable, the yield is high, and the processing steps are reduced, and the processing efficiency is significantly improved. Among them, the minimum wall thickness of the main body of the finished part, namely the cabin-type thin-walled part 2, is 2mm, and the minimum processing tolerance is 0.075.

[0033] Further, see attached document. Figure 2To prevent uneven material flow from causing eccentricity, the technical solution adopted in this invention further includes a process boss portion 13 on the blank 1. The process boss portion 13 is located on the side of the blank 1 opposite to the two first irregular portions 11. Through comparison and actual verification, the process boss portion 13 can effectively prevent uneven material flow.

[0034] In summary, based on the above, this invention proposes a processing method for thin-walled cabin parts. A high-precision continuous extrusion blank 1 with irregularly shaped portions replaces the round tube blank. This blank 1 is manufactured using a continuous profile extrusion process and has a contour similar to the cabin-type thin-walled part 2. The dimensions of the finished part, i.e., the cabin-type thin-walled part 2, can be achieved through a small amount of subsequent milling. This processing method reduces the amount of material removed during part processing, effectively reducing internal stress during processing. The finished part, i.e., the cabin-type thin-walled part 2, has stable dimensions, improved yield, fewer processing steps, and significantly improved processing efficiency. The blank 1 can be reduced in weight by more than 50%, thus reducing energy consumption.

[0037] Specifically, the thin-walled cabin parts 2 with irregular shapes processed by the above-mentioned thin-walled cabin parts processing method have stable dimensions, improved yield, reduced processing steps, significantly improved processing efficiency, and the blank 1 can be reduced in weight by more than 50%, which can reduce energy consumption.
