DETAILED DESCRIPTION

[0051] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0052] Embodiment 1

[0053] like Figure 1 As shown, the present invention provides a manual pipe bending device for a turbojet engine oil supply pipeline, comprising:

[0054] A bottom plate 1, on which a plurality of mounting holes are provided;

[0055] A positioning column 2, the positioning column 2 is fixedly mounted on the bottom plate 1 through a mounting hole, and a pipe bending module for pipe bending is fixedly arranged on the top of the positioning column 2;

[0056] The rotating disk 3 is slidably sleeved on the outer side of the positioning column 2, a handle 4 is fixedly connected to the side wall of the rotating disk 3, and a limit block 5 is fixedly connected to the top of the rotating disk 3, and the limit block 5 is correspondingly arranged with the pipe bending module; an angle scale line is arranged on the bottom plate 1, and the angle scale line is used to determine the rotation angle of the rotating disk 3 during the pipe bending process;

[0057] The bending die 6 is fixedly mounted on the bottom plate 1 and is arranged corresponding to the pipe bending module. The bending die 6 is used to determine the spacing of the pipe bending.

[0058] When the present invention is in use, the pipeline to be bent is placed on the top of the positioning column 2, and the pipeline is clamped by the pipe bending module. At this time, the rotating disk 3 is in the initial position, and the limit block 5 is in contact with the clamped pipeline. Then, the rotating disk 3 is rotated by the handle 4, and the limit effect between the limit block 5 and the pipe bending module is utilized to bend the pipeline. Before bending the pipeline, the bending distance of the pipeline is determined by the bending mold 6, so as to ensure the high consistency of the finished product after the pipeline is bent.

[0059] The present invention positions the pipeline by setting a pipe bending module, and determines the bending position and bending spacing of the pipeline by means of a bending die 6. There is no need to repeatedly measure the required spacing when bending the pipeline. After bending the pipeline once, the rotating disk 3 is reset, and the pipeline can be positioned again by means of the bending die 6 and the pipe bending module, so as to facilitate the next bending operation. The present invention has the advantages of simple operation and strong consistency in mass production.

[0060] A further optimized solution is that the bending pipe module includes a pair of relatively arranged positioning blocks 7, a gap for placing the pipeline is set between the two positioning blocks 7, and the gap is set along the radial direction of the positioning column 2; wherein, one end of a positioning block 7 close to the limit block 5 is an arc-shaped structure, and the arc-shaped structure is located on the side of the positioning block 7 close to the gap.

[0061] Further optimizing the solution, the top surface of the bending die 6 is provided with two forming grooves, and the bottom of the forming grooves is flush with the top surface of the positioning column 2;

[0062] A molding groove includes a horizontal positioning section 61 and a first V-shaped positioning section 62. The horizontal positioning section 61 and the gap are located on the same axis. The first pipeline positioning surface 63 is provided at one end of the horizontal positioning section 61 close to the first V-shaped positioning section 62.

[0063] Another forming groove includes a straight positioning section 64 and a second V-shaped positioning section 65. An angle is set between the straight positioning section 64 and the gap. A second pipeline positioning surface 66 is set at one end of the straight positioning section 64 close to the second V-shaped positioning section 65. The structure of the second V-shaped positioning section 65 is the same as the mirror image structure of the first V-shaped positioning section 62.

[0064] The manual pipe bending device for the turbojet engine fuel supply pipeline provided by the present invention has the following specific operation process:

[0065] S1. Select a suitable bending mold 6 according to the bending requirements of the pipe to be bent, and fix the bending mold 6 on the bottom plate 1;

[0066] S2, make the rotating disk 3 in the initial position, place one end of the pipeline to be bent against the first pipeline positioning surface 63, and at the same time, make the pipeline located in the gap between the two positioning blocks 7, as shown in FIG. Figure 2 As shown;

[0067] S3, according to the angle of the first V-shaped positioning section 62, the rotating disk 3 is rotated by the handle 4, the limit block 5 on the rotating disk 3 is used to bend the pipeline, and the angle of the pipeline bending is determined according to the angle scale line on the bottom plate 1, until the angle of the pipeline bending is the same as the angle of the first V-shaped positioning section 62, such as Figure 3 As shown;

[0068] S4, take out the pipe that has been bent once, make the bent end of the pipe against the second pipe positioning surface 66, and make the pipe stuck between the two positioning blocks 7, as shown in FIG. Figure 4 Then, the rotating disk 3 is rotated by the handle 4 to bend the pipeline again. The bending angle is the angle between the horizontal positioning section 61 and the first V-shaped positioning section 62, as shown. Figure 5 As shown;

[0069] S5, the portion of the pipeline after the second bending is adapted to the shape of the forming groove with the horizontal positioning section 61, and after the pipeline passes through the forming groove to determine the spacing of the pipeline bending, the handle 4 and the limit block 5 are used to bend the pipeline for the third time, such as Figure 6 As shown;

[0070] S6, after the pipe bent in S5 is passed through another forming groove to determine the bending distance of the pipe, the pipe is bent for the fourth time using the handle 4 and the limit block 5. Figure 7 As shown; the bending operation of the pipe is completed.

[0071] Embodiment 2

[0072] like Figure 8 As shown, the difference between this embodiment and the first embodiment is that, in order to reduce and eliminate the amount of rebound after the pipe is bent, thereby ensuring that the bent pipe can be normally placed in the forming groove, and ensuring the consistency of the size of the finished product after the pipe is bent, an electromagnetic heating coil 8 is arranged on the top of the positioning column 2, and the electromagnetic heating coil 8 is used to heat the bent part of the pipe.

[0073] During the specific bending operation, each time the pipeline is bent, the electromagnetic heating coil 8 needs to be started to heat the bent portion of the pipeline to soften the pipeline material, reduce the yield stress of the pipeline material, and thus reduce the rebound amount.

[0074] A further optimized solution is that when the bending part of the pipeline is heated, in order to keep the position of the rotating disk 3 unchanged, one end of the limit block 5 is slidably matched with the top surface of the positioning column 2, and an iron plate is fixedly provided on the top of the positioning column 2, and an electromagnet is provided at the end of the limit block 5 that contacts the positioning column 2. When the electromagnet is energized, the limit block 5 is magnetically fixed to the positioning column 2;

[0075] A switch 1 is provided on the handle 4, and the switch 1 is used to control the on-off of the circuit of the electromagnet.

[0076] The positioning column 2 is fixed by the electromagnet magnetic attraction so that the relative position of the positioning column 2 and the limit block 5 will not change, thereby ensuring that the pipeline will not be deformed again when the bending part of the pipeline is heated.

[0077] Embodiment 3

[0078] like Fig. 9 As shown, the difference between this embodiment and the first and second embodiments is that a power-assisting mechanism 9 is added to assist in the bending operation of the pipeline, thereby reducing the labor intensity of the workers. Specifically, the power-assisting mechanism 9 is installed on the side of the base plate 1 away from the rotating disk 3, and the power-assisting mechanism 9 is used to assist in driving the rotating disk 3 to rotate.

[0079] The assist mechanism 9 can adopt two structural forms. The first one is a structural form that relies on the structure itself and does not require an additional external power supply; the second one is a structural form that uses an external power supply.

[0080] like Fig.10 As shown, the first structural form of the power assist mechanism 9 includes:

[0081] A housing 91, wherein the housing 91 is fixedly mounted on the base plate 1;

[0082] Torsion spring 92, torsion spring 92 is arranged in the shell 91 and is coaxially arranged with the positioning column 2; an arc-shaped through hole is opened on the base plate 1, one end of the torsion spring 92 passes through the arc-shaped through hole and is fixedly connected to the rotating disk 3, and the other end of the torsion spring 92 is fixedly connected to the shell 91; when the rotating disk 3 is in the initial position, the torsion spring 92 is in a stressed state.

[0083] With this type of structural assist mechanism 9, when the rotating disk 3 is in the initial position, the torsion spring 92 itself is in a stressed state. During the process of bending the pipeline by the rotating disk 3, the torsion spring 92 gradually recovers, and the elastic force of the torsion spring 92 is used to assist the manual bending process, thereby reducing the labor intensity of the workers.

[0084] like Fig.11 As shown, the second structural form of the power assist mechanism 9 includes:

[0085] A housing 91, wherein the housing 91 is fixedly mounted on the base plate 1;

[0086] The motor 93 is fixedly disposed in the housing 91;

[0087] Gear transmission assembly, a through hole is opened on the bottom plate 1, the interior of the rotating disk 3 is a cavity, a ring gear ring 94 is fixedly connected to one side of the cavity wall, the ring gear ring 94 is coaxially arranged with the positioning column 2, and the motor 93 and the rotating disk 3 are driven and matched through the gear transmission assembly and the ring gear ring 94;

[0088] Switch 2: Switch 2 is arranged on the handle 4 , and switch 2 is used to control the start and stop of the motor 93 .

[0089] Among them, the gear transmission assembly includes:

[0090] A large gear 95, which is fixedly mounted on the output shaft of the motor 93;

[0091] A rotating shaft 96, one end of which is rotatably connected to the housing 91, and the other end of which extends into the cavity through the through hole;

[0092] A small gear 97, which is fixedly sleeved on the rotating shaft 96 and meshes with the large gear 95;

[0093] The meshing gear 98 is fixedly sleeved on the rotating shaft 96 , and the meshing gear 98 is meshed with the annular gear ring 94 .

[0094] The power assist mechanism 9 of this structural form starts the motor 93 through the switch 2 when performing the pipe bending operation, and the motor 93 drives the large gear 95 to rotate, the large gear 95 drives the small gear 97 to rotate, the small gear 97 drives the meshing gear 98 to rotate through the rotating shaft 96, and the meshing gear 98 and the annular gear ring 94 drive the rotating disk 3 to rotate. The setting of the motor 93 can greatly reduce the force of the workers when bending the pipe, thereby reducing the labor intensity of the workers.

[0095] Embodiment 4

[0096] To further optimize the solution, in order to quickly determine the rotation angle of the rotating disk 3, improve the efficiency of pipeline bending, and facilitate the positioning of the initial position of the rotating disk 3, a plurality of blocks 10 are slidably arranged on the bottom plate 1, wherein two blocks 10 are used to limit the initial position of the rotating disk 3, and the remaining blocks 10 are arranged along the circumference of the rotating disk 3 to limit the rotation angle of the rotating disk 3.

[0097] When in use, the top and bottom of the stopper 10 can extend out of the top and bottom surfaces of the bottom plate 1, respectively. That is, when the top end of the stopper 10 extends out of the top surface of the bottom plate 1, the bottom end of the stopper 10 enters the interior of the bottom plate 1. Conversely, when the top end of the stopper 10 enters the interior of the bottom plate 1, the bottom end of the stopper 10 extends out of the bottom surface of the bottom plate 1. Fig.12 and 13 shown.

[0098] The stopper 10 maintains the current position by the friction between the stopper 10 and the bottom plate 1. At the same time, in order to prevent the stopper 10 from falling off the bottom plate 1, a receiving cavity is provided inside the bottom plate 1, and a connecting plate 101 is arranged in the receiving cavity to fix the connecting plate 101 to the stopper 10, thereby preventing the stopper 10 from falling off the bottom plate 1. In order to increase the friction between the stopper 10 and the bottom plate 1, a gasket made of elastic material is coated on the bottom of the stopper 10. The deformation of the gasket is used to make the stopper 10 stuck on the bottom plate 1 without affecting the up and down sliding of the stopper 10.

[0099] By controlling the top end of the stopper 10 at different positions to extend out of the bottom plate 1, the movable range of the handle 4 can be limited, thereby facilitating the bending operation of the pipeline.

[0100] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
