Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein.

First aspect

An embodiment of the present application provides a bellows manufacturing system, as shown in fig. 1 to 12, the bellows manufacturing system includes: a first device 10, a second device 20 and a third device 30. The first device 10 performs a primary forming process on the first position of the plate 40 by using an expansion forming process, and after the primary forming process, a first arc-shaped convex part protruding towards the first surface 401 far away from the plate 40 is formed at the first position of the plate 40. The second device 20 performs secondary shaping on the first position of the plate 40 by using a roll forming process, after the secondary shaping, a first arc-shaped concave portion 403 protruding towards the second surface 402 far away from the plate 40 and a second arc-shaped convex portion 404 protruding towards the first surface 401 are formed at the first position of the plate 40, the second arc-shaped convex portion 404 is further shaped as the first arc-shaped convex portion, and the second surface 402 of the plate 40 and the first surface 401 of the plate 40 are opposite to each other. The third apparatus 30 shears the second location of the sheet material 40 using a roller shear process. The first position and the second position are two positions on the plate 40 which are sequentially distributed along the first direction, and the first position and the second position of the plate 40 correspond to two axial ends of the corrugated pipe respectively.

Specifically, the expansion forming process described above refers to a press working method in which a die is used to force a plate material to be reduced in thickness and increased in surface area to obtain a geometric shape of a part. Such as: after the first end face 111 of the bulging die 11 abuts against the first position of the plate material 40, the bulging die 11 pushes the plate material 40 under the action of the first driving device, so that the first position of the plate material 40 is forced to form a first arc-shaped convex part which is consistent with the shape of the first end face 111 of the bulging die 11. In specific implementation, the plurality of positions of the plate 40 can be shaped once according to requirements, so that the number of the first arc-shaped convex parts can be increased.

The roll forming process refers to a processing method for rolling and processing various products with complex shapes, such as shaft rods, valve cores, special fasteners and the like, by plastic movement of materials. Such as: after the rolling wheels 211 abut against the first position of the plate 40 on the first bearing table 22 by the second driving device, the rolling wheels 211 rotate while translating in the second direction relative to the plate 40, so that the rolling wheels 211 roll the first position of the plate 40, and thus the first position of the plate 40 forms the first arc-shaped concave part 403 and the second arc-shaped convex part 404 distributed in the first direction.

The rolling shear process refers to a processing method of rolling the first structural member on the second structural member to break the rolled position of the plate material between the first structural member and the second structural member. Such as: after the hob 311 is abutted to the second position of the plate 40 on the second bearing table 32 by the fourth driving device, the hob 311 rotates while translating in the second direction relative to the plate 40, so that the hob 311 performs rolling shearing on the second position of the plate 40, and the second position of the plate 40 is disconnected.

When manufacturing the corrugated tube, first, a sheet material 40 is prepared, and the sheet material 40 has a first surface 401 and a second surface 402 which are opposite to each other. Then, the first position of the plate material 40 is primarily formed through an expansion forming process so that a first arc-shaped convex part protruding towards a first surface 401 far away from the plate material 40 is formed at the first position of the plate material 40, the first position of the plate material 40 is secondarily formed through a roll forming process so that a first arc-shaped concave part 403 protruding towards a second surface 402 far away from the plate material 40 and a second arc-shaped convex part 404 protruding towards the first surface 401 are formed at the first position of the plate material 40, and the second position of the plate material 40 is sheared through a rolling shearing process. And finally, welding two ends of the plate 40 along a second direction perpendicular to the first direction to complete the manufacture of the corrugated pipe. That is, the corrugation of the sheet material 40 is preformed by the first apparatus 10, and then the shape of the corrugation of the sheet material 40 is adjusted by the second apparatus 20, thereby forming a preset corrugated shape of the corrugated tube.

In one embodiment of the bellows, the bellows made by the bellows making system of the present application is disposed at the joint between the gas turbine and the gas turbine exhaust diffuser, and the gas turbine, the bellows, and the gas turbine exhaust diffuser extend in a first direction, that is, the bellows made by the system of the present application connects the gas turbine exhaust diffuser and the gas turbine, and the end of the plate 40 corresponding to the first position is connected to the gas turbine, and the end of the plate 40 corresponding to the second position is connected to the gas turbine exhaust diffuser. The bellows between the gas turbine and the gas turbine exhaust diffuser is capable of absorbing thermal displacements between the gas turbine and the gas turbine exhaust diffuser and initial displacements of the gas turbine. Here, since the first, second, and

third apparatuses

10, 20, and 30 are not connected to each other, that is, the first, second, and

third apparatuses

10, 20, and 30 are independent from each other, one or more of the first, second, and

third apparatuses

10, 20, and 30 can be replaced according to the size of the gas turbine and the connection of the gas turbine exhaust diffuser and the bellows.

In the first embodiment, the first apparatus 10, the second apparatus 20, and the third apparatus 30 cooperate to manufacture the corrugated pipe, but the expansion forming process and the roll forming process have lower costs than the hydroforming process, so that the manufacturing cost of the corrugated pipe can be reduced, and the expansion forming process and the roll forming process are simple, so that the manufacturing efficiency of the corrugated pipe can be improved. In addition, compare the environmental pollution that the medium brought that the hydroforming technology needs regularly to be changed, bellows manufacturing system in this application does not need this operation, can protect the environment from this. Second, the sheet material 40 is preformed by the first apparatus 10, and the sheet material 40 after the preforming is secondarily molded by the second apparatus 20 to adjust the shape of the sheet material 40, thereby reducing damage to the sheet material 40 by the manufacturing system of the one-shot molding type only. Thirdly, since the first device 10, the second device 20, and the third device 30 are not connected, that is, the first device 10, the second device 20, and the third device 30 are independent of each other, one or more devices can be replaced according to actual situations, so that the replaceability is high (that is, the limitation of the bellows manufacturing system is low), for example: the first apparatus 10 is replaced so that the first arcuate projections are of different sizes.

Next, the first device 10, the second device 20, and the third device 30 will be described.

First, the first apparatus 10 is described.

In some embodiments, as shown in fig. 1-5, the first device 10 comprises: the device comprises a plurality of bulging dies 11 and a first driving device, wherein the plurality of bulging dies 11 are spliced into a circle, the outer edge profile of the circle of bulging dies 11 is circular, the first driving device is connected with the plurality of bulging dies 11, the first driving device can drive the plurality of bulging dies 11 to move in a divergent mode, and the first driving device can drive the plurality of bulging dies 11 to reset after moving in the divergent mode; after the circle of bulging dies 11 moves in a divergent mode, the plate material 40 attached to the outline of the outer edge of the circle of bulging dies 11 expands to form a first arc-shaped convex part.

Specifically, the shapes and sizes of the bulging dies 11 may be completely the same or partially different, for example: the lengths of the edges of the outer edge contour of two bulging dies 11 corresponding to one circle of bulging dies 11 are different. It will be understood that the number of the expansion dies 11 in a circle of expansion dies 11 may vary according to the size and shape of the expansion dies 11, and can be made according to practical situations, such as: the raw material for manufacturing the bulging dies 11 is leftover materials left after other structural members are manufactured, so that the number of the bulging dies 11 in one circle of the bulging dies 11 is relatively larger. It is understood that a plurality of circles of the expanding die 11 may be disposed on the first apparatus 10, and the plurality of circles of the expanding die 11 are arranged along the first direction, so that a plurality of first arc-shaped protrusions arranged along the first direction can be formed on the plate material 40 after one-time forming.

The first driving device in the above may be a device including: a first driving structure connected to each of the expansion dies 11, the first driving structure being capable of driving the movement of each of the expansion dies 11 individually. The first driving device may include: a plurality of second drive structures, one second drive structure coupled to one of the expansion dies 11, such that one second drive structure is capable of actuating one of the expansion dies 11 in response thereto.

When the expansion die is used, the first driving device drives the expansion dies 11 to move in a divergent mode, so that the plate 40 attached to the outline of the outer edge of one circle of expansion die 11 expands to form a first arc-shaped convex part, and then the first driving device drives the expansion dies 11 to reset so as to take down the plate 40.

In this embodiment, the expansion forming process can be performed by the cooperation of the first driving device and the plurality of bulging dies 11, so that the first position of the plate material 40 is formed with a first arc-shaped convex portion protruding toward the first surface 401 away from the plate material 40.

In some embodiments, referring to fig. 1 to fig. 5, the first end surface 111 and the second end surface 112 of the swelling mold piece 11 are opposite to each other, the first end surface 111 of the swelling mold piece 11 is arc-shaped and convex in a direction away from the second end surface 112, the swelling mold piece 11 is in a decreasing trend in a direction from the first end surface 111 to the second end surface 112, and the first end surface 111 of the swelling mold piece 11 corresponds to an outer edge profile of one circle of the swelling mold piece 11; a convex strip 113 is protruded on the surface of the bulging die piece 11 between the first end surface 111 and the second end surface 112, the convex strip 113 is arranged close to the first end surface 111, and the trend of the convex strip 113 is consistent with that of the first end surface 111; the convex strips 113 of the expansion dies 11 are all positioned at one side of one circle of expansion dies 11, and the convex strips 113 of the expansion dies 11 are spliced into a ring.

Specifically, the bulging die piece 11 in the above description has a tendency to decrease in a direction from the first end surface 111 to the second end surface 112, where the bulging die piece 11 may have a tendency to decrease gradually in a direction from the first end surface 111 to the second end surface 112, may have a tendency to decrease gradually after bending, and then gradually decrease as shown in fig. 1 to 4, and may have other arrangements, which are not particularly limited herein. The first end face 111 of the bulging die 11 corresponds to the outline of the outer edge of one circle of bulging die 11, that is, the first end faces 111 of a plurality of bulging dies 11 are spliced to form the outer edge of one circle of bulging die 11. The included angle between the protruding strip 113 and the bulging die 11 can be set according to actual requirements, for example: the ribs 113 are perpendicular to the expansion die 11 as shown in figures 1-5. The distance between the protruding strip 113 and the first end surface 111 of the bulging die 11 can be set according to actual requirements, for example: when the inner diameter of the bellows needs to be increased, the distance between the ridge 113 and the first end surface 111 of the bulging die 11 is decreased. The direction of the convex strip 113 is consistent with the direction of the first end surface 111, in other words, the convex strip 113 is arc-shaped, and the radian of the convex strip 113 is consistent with the radian of the first end surface 111.

In the embodiment, firstly, the bulging die 11 has a simple structure, so that the bulging die 11 is not only convenient to manufacture, but also low in manufacturing cost. Secondly, in the process of primary shaping of the first position of the plate material 40 by one circle of bulging dies 11, the convex strips 113 abut against the second surface 402 of the plate material 40, so that damage to the plate material 40 can be reduced.

In some embodiments, referring to fig. 1 to 5, a ring of the swelling dies 11 forms a ring structure having through holes 12, the first driving device extends into the through holes 12, and the first driving device located in the through holes 12 can drive the plurality of swelling dies 11 to move synchronously. Here, the first driving device located in the through hole 12 can drive the plurality of bulging dies 11 to move synchronously, so that the driving force of the first driving device and the driven bulging dies 11 are located in the same plane, so that the driving force of the first driving device can be reduced, and the first driving device extends into the through hole 12, so that the first driving device 12 occupies a small additional space.

In some embodiments, referring to fig. 1-5, the expansion die 11 and the first drive mechanism are removably attached, i.e., the expansion die 11 is removable from the first drive mechanism. Then, the bulging die 11 of the first size can be detached from the first driving device, and the bulging die 11 of the second size different from the first size can be connected to the first driving device, so that the size of the first arc-shaped protrusion on the plate material 40 after the completion of the manufacturing by the first apparatus 10 and/or the inner diameter of the manufactured corrugated pipe can be changed.

Specifically, the surfaces of the first protrusions 2111 facing the first stage 22 may be in the same plane or different planes, and may be provided according to actual conditions. The first concave portions 2211 can be realized by arranging two opposite convex portions on the first bearing platform 22, and the number of the first convex portions 2111 and the number of the first concave portions 2211 can be set according to actual requirements, for example, referring to fig. 7, the number of the first convex portions 2111 is 3, and two convex portions are protruded on the first bearing platform 22 to form 3 first concave portions 2211.

While the first protrusion 2111 can be moved back and forth in the first direction, so that the distance between two adjacent first protrusions 2111 can be adjusted, since the first platform 22 is provided with the first recess 2211 at a position corresponding to the first protrusion 2111, the first recess 2211 may or may not be adjusted accordingly when the first protrusion 2111 is adjusted.
