Technical Field
[0001] The utility model relates to the technical field of aerospace manufacturing, in particular to an angular auxiliary forming tool for aircraft wastewater and gray water pipelines. Background Art
[0002] The aircraft's wastewater and graywater pipelines are mainly responsible for collecting and treating the wastewater and graywater generated during the aircraft's operation. Due to the limited space inside the aircraft, such as Figure 5 As shown, wastewater and greywater pipelines are mostly set at eccentric angles to flexibly arrange the pipelines, avoid interference with other equipment or pipelines, and optimize the spatial layout.
[0003] The applicant has discovered that the prior art has at least the following technical problems:
[0004] Existing ordinary pipe bending machines lack a universal and efficient auxiliary bending tooling, which means that they can only perform single-dimensional bending operations and cannot meet the manufacturing requirements of multi-dimensional and high-precision angular angles of pipelines. There are limitations in their use, which restricts their application in the field of aerospace manufacturing technology.
[0005] Based on this, at present, the manufacturing of the anisotropic angles of aircraft wastewater and gray water pipelines mainly relies on CNC pipe bending machines. Although CNC pipe bending machines have the ability to manufacture multi-dimensional and high-precision anisotropic angles, the purchase cost and maintenance costs of CNC pipe bending machines are high, the maintenance process is complicated, and the professional requirements for operators are extremely high, which in turn increases the economic burden and operational difficulty of production companies.
[0006] In view of this, the present utility model is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide an auxiliary forming tool for the yaw angle of aircraft wastewater and graywater pipes. This solves the technical problem that conventional pipe bending machines in the prior art lack a universal and efficient auxiliary bending tool, resulting in their limited ability to perform single-dimensional bending operations and an inability to meet the requirements for multi-dimensional, high-precision yaw angle manufacturing. This limitation restricts their application in the field of aerospace manufacturing technology. The various technical effects achieved by the preferred technical solution among the various technical solutions provided by this utility model are detailed below.
[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0012] Preferably, the clamping mechanism comprises an upper clamping portion and a lower clamping portion, and grooves are provided on opposite surfaces of the upper clamping portion and the lower clamping portion to enclose and form a clamping space, and the wing plates of the two are detachably connected by bolts.

[0017] The preferred technical solution of the utility model can also produce at least the following technical effects:
[0018] The utility model effectively avoids the technical problem that the common pipe bending machine in the prior art lacks a universal and efficient auxiliary bending tool, which results in it being able to perform bending operations in only one dimension and being unable to meet the manufacturing requirements of multi-dimensional and high-precision skew angles, and having limitations in use, which restricts its application in the field of aerospace manufacturing technology.

The utility model forms a universal and efficient auxiliary bending tool through the coordinated action of a core mold, a clamping mechanism, a pointer arm, an angle plate and a positioning mechanism, which can be combined to perform multi-dimensional and high-precision eccentric angle manufacturing operations in conjunction with an ordinary pipe bending machine. Among them, an axial scale line is provided on the core mold to facilitate the precise adjustment of the bending length and position of the pipeline. The clamping mechanism is used to firmly clamp the pipeline to be manufactured. The pointer arm is used to indicate and record the bending angle of the pipeline.

DETAILED DESCRIPTION
[0028] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0029] like Figure 1-4 As shown, the utility model provides an angular auxiliary forming tool for aircraft wastewater and graywater pipelines, including a core mold 1, a clamping mechanism 2, a pointer arm, an angle disk 4 and a positioning mechanism; an axial scale line 11 is provided on the core mold 1; the clamping mechanism 2 is slidably mounted on the core mold 1 and has a clamping space 23 for clamping the pipeline; the positioning mechanism is slidably mounted on the core mold 1, the first end face of the positioning mechanism is connected to the angle disk 4, and the second end face abuts the clamping mechanism 2 and the pipeline; the pointer arm is hinged to the clamping mechanism 2 and is used to point to the angle scale line 41 of the angle disk 4.
[0030] Through the coordinated action of the core mold 1, the clamping mechanism 2, the pointer arm, the angle disk 4 and the positioning mechanism, a universal and efficient auxiliary bending tool is formed in combination, which can be used in conjunction with an ordinary pipe bending machine to perform multi-dimensional and high-precision eccentric angle manufacturing operations. Among them, an axial scale line 11 is provided on the core mold 1 to facilitate precise adjustment of the bending length and position of the pipeline. The clamping mechanism 2 is used to firmly clamp the pipeline to be manufactured. The pointer arm is used to indicate and record the bending angle of the pipeline. The positioning mechanism can provide stable support and positioning for the clamping mechanism 2 and the pipeline during the bending process, ensuring the accuracy of the bending angle, and by adjusting the position of the positioning mechanism on the core mold 1, different bending starting points can be set, thereby realizing multi-dimensional and high-precision eccentric angle manufacturing, meeting the high-standard manufacturing requirements of aircraft wastewater and gray water pipelines.
[0031] The tooling cost of the utility model is low, and high-precision skew angle manufacturing can be achieved when used in conjunction with an ordinary pipe bending machine. Compared with a CNC pipe bending machine, the operation difficulty is low, which greatly reduces the purchase cost and maintenance cost of the enterprise.
[0032] As an optional implementation, a limiting hole is provided on the core mold 1, and the limiting hole is arranged along the axial direction of the core mold 1; a linear segment 6 is provided on the first end face of the positioning mechanism, and the upper part of the linear segment 6 is a planar structure 61, and a positioning hole 63 is opened, and the positioning hole 63 is adapted to the limiting hole.
[0033] Furthermore, the positioning mechanism includes a positioning plate 5 .
[0034] The linear segment 6 is concentrically arranged with the positioning plate 5 and is slidably sleeved on the core mold 1 .
[0035] By cooperating with the limiting hole and the positioning hole 63 , the position of the positioning plate 5 can be conveniently adjusted without complicated calculations or measurements, thereby reducing the difficulty of operation and the error rate.
[0036] Fasteners such as bolts are passed through the positioning holes 63 and the limiting holes in sequence to ensure a firm connection between the positioning plate 5 and the core mold 1, thereby achieving precise positioning of the positioning plate 5.
[0037] Since the upper portion of the linear segment 6 is a planar structure 61 , fasteners such as bolts can abut against it, further improving the stability and reliability of the connection.
[0038] It should be noted that the number and arrangement of the limiting holes can be designed according to usage requirements.
[0039] As an optional embodiment, a positioning groove 62 is provided on the upper portion of the linear segment 6 , and the positioning groove 62 extends in the axial direction.
[0040] The positioning groove 62 can expose the limiting hole on the core mold 1, which is convenient for the operation of fasteners such as bolts, so as to better realize the positioning of the positioning plate 5.
[0041] As an optional embodiment, the clamping mechanism 2 includes an upper clamping portion 21 and a lower clamping portion 22. Grooves are provided on the opposite surfaces of the upper clamping portion 21 and the lower clamping portion 22 to enclose a clamping space 23, and the wing plates of the two are detachably connected by bolts.
[0042] The grooves of the upper clamping portion 21 and the lower clamping portion 22 together enclose a clamping space 23 for clamping the pipeline, so that the pipeline is firmly clamped during the bending process.
[0043] As an optional embodiment, the wing plates of the upper clamping portion 21 and the lower clamping portion 22 are correspondingly provided with connecting holes 211 .
[0044] Fasteners such as bolts are passed through the two connection holes 211 respectively, so that the upper clamping part 21 and the lower clamping part 22 are firmly connected together, so that the pipeline is firmly clamped, and assembly and disassembly are convenient.
[0045] As an optional embodiment, a connecting groove 212 is provided on the upper clamping portion 21, and a sharp pointer tip 31 is provided at the first end of the pointer arm for pointing to the angle scale line 41 of the angle disk 4, and the second end is connected to the connecting groove 212 through a rotating member.
[0046] As an optional embodiment, a receiving groove is opened on the first end surface of the positioning plate 5, and the angle plate 4 is arranged in the receiving groove and fixed by fasteners such as bolts.
[0047] Furthermore, the first end surface of the angle plate 4 protrudes from the positioning plate 5 .
[0048] As an optional embodiment, the pointer tip 31 is perpendicular to the pointer arm and is provided with an avoidance groove 32 so that the pointer tip 31 can extend onto the angle plate 4 .
[0049] The pointer tip 31 can extend to the angle disc 4, so that the pointer tip 31 can more directly and accurately point to the angle scale line 41 on the angle disc 4. Moreover, the portion of the pointer tip 31 extending to the angle disc 4 is higher than the surface of the angle disc 4 to avoid friction.
[0050] The operating steps of this utility model are:
[0051] S1: Slide the positioning plate 5 onto the core mold 1, with the first end face of the angle plate 4 facing the operator; align the positioning hole 63 of the positioning plate 5 with the limiting hole on the core mold 1, and use bolts to pass through the positioning hole 63 and the limiting hole to firmly fix the positioning plate 5 on the core mold 1;
[0052] S2: The clamping mechanism 2 is also mounted on the core mold 1, and the clamping end of the pipe to be manufactured is placed in the clamping space 23 formed between the upper clamping part 21 and the lower clamping part 22. Then, bolts are passed through the connecting holes 211 of the upper clamping part 21 and the lower clamping part 22, and the bolts are tightened to firmly clamp the pipe.
[0053] It should be noted that the manufacturing end of the pipe to be manufactured and the core mold are clamped by the corresponding clamping mechanism on the pipe bending machine;
[0054] S3: The clamping mechanism 2 is driven to move closer to the positioning plate 5 until the two contact each other, and the position of the clamping mechanism 2 is adjusted so that the pointer tip 31 of the pointer arm accurately points to the 0° scale line on the angle plate 4. In this way, in subsequent bending operations, the pointer arm will be able to accurately indicate the bending angle of the pipeline;
[0055] S4: First, the starting position or axial dimension of the first bend is recorded using the axial scale line 11 on the core mold 1; then, the pointer arm is rotated away from the angle disk 4 to avoid interference during the bending process, and the corresponding bend angle value is input on the pipe bender. The pipe clamping mechanism of the pipe bender fixes the manufacturing end of the pipe to manufacture the first bend;
[0056] S5: After completing the first bend, loosen the bolts to release the locking state between the positioning plate 5 and the core mold 1; then, based on the straight-line distance between the two bends on the drawing and using the axial scale line 11 on the core mold 1 as a reference, drive the positioning plate 5 together with the clamping mechanism 2 and the pipeline to move synchronously to the specified position; then, relock the positioning plate 5 and the core mold 1;
[0057] S6: According to the rotation direction and rotation angle of the first and second bends on the drawing, adjust the position of the clamping mechanism 2 until the pointer tip 31 of the pointer arm accurately points to the corresponding scale line on the angle disk 4; rotate the pointer arm again to keep it away from the angle disk 4 to avoid interference; then enter the bend angle value of the second bend on the pipe bender, start the pipe bender, and use the pipe clamping mechanism of the pipe bender to keep the pipe stable to manufacture the second bend.
[0058] S7: If the pipeline needs to make more bends, repeat steps S5 and S6, adjust the pipeline position according to the drawing requirements and make corresponding bends.
