[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] First,

[0031] The present application embodiment discloses a flange for a hose. Figure 1 and Figure 2The hose flange includes a flange body 1, which is tubular, and a first flange portion 2 is fixed to the end of the flange body 1 by an integral molding method, and a second flange portion 3 is fixed to the end of the flange body 1 away from the first flange portion 2 by an integral molding method, and guide surfaces 4 are provided between the first flange portion 2, the second flange portion 3 and the flange body 1, and the diameter of the first flange portion 2 is smaller than the diameter of the flange body 1, and the diameter of the second flange portion 3 is larger than the diameter of the flange body 1, and the interiors of the first flange portion 2, the second flange portion 3 and the flange body 1 are all hollow, and their internal diameters are the same.

[0032] Second,

[0033] The present application also discloses a processing die suitable for the above-mentioned hose flange, referring to Figure 1 and Figure 2 The processing molds suitable for the above-mentioned hose flange include a first mold 5, a second mold 6, a third mold 7, a fourth mold 8, a fifth mold 9, and a sixth mold 10; the first mold 5 includes a first upper mold 11 and a first lower mold 12, and the first lower mold 12 is provided with a first groove 13. The first groove 13 includes two spaces with different diameters, and the diameter of the space close to the first upper mold 11 is larger than the diameter of the space far from the first upper mold 11. During the processing, the raw material enters the first groove 13 and is squeezed to make it have the same shape as the internal shape of the first groove 13. At this time, the first flange part 2 is preliminarily processed on the flange body 1.

[0034] Reference Figure 1 and Figure 2 The second mold 6 includes a second upper mold 14 and a second lower mold 15. The second lower mold 15 is provided with a second groove 16. The second groove 16 includes three spaces with different diameters. The three spaces with different diameters decrease in diameter from a position close to the second upper mold 14 to a position away from the second upper mold 14. During the processing, the raw material processed in the first mold 5 is transferred to the second mold 6 and processed in the second groove 16. At this time, the first flange part 2 and the second flange part 3 are preliminarily processed on the flange body 1. At the same time, the length of the inner space of the second groove 16 in the axial direction is less than the length of the inner space of the first groove 13 in the axial direction.

[0035] Reference Figure 1 and Figure 2The third mold 7 includes a third upper mold 17 and a third lower mold 18. The third lower mold 18 is provided with a third groove 19. The third groove 19 includes three spaces with different diameters. The diameters of the three spaces decrease successively from a position close to the third upper mold 17 to a position away from the third upper mold 17, which is convenient for the molding process of the flange body 1, the first flange part 2 and the second flange part 3. At the same time, a first stretching rod 20 is fixed to the bottom of the third groove 19 by an integrated molding method. The first stretching rod 20 is used to process the first flange part 2, so that after the raw material processed in the second mold 6 enters the third mold 7, the first stretching rod 20 contacts the raw material, so that the interior of the first flange part 2 is hollow.

[0036] Reference Figure 1 and Figure 2 The fourth mold 8 includes a fourth upper mold 21 and a fourth lower mold 22. The fourth lower mold 22 is provided with a fourth groove 23. The fourth groove 23 has the same internal shape as the third groove 19. At the same time, a first stretching rod 20 is fixed to the bottom of the fourth groove 23. The first stretching rod 20 at the bottom of the fourth groove 23 is the same as the first stretching rod 20 at the bottom of the third groove 19. A second stretching rod 24 is fixed to the end of the fourth upper mold 21. The second stretching rod 24 is used to process the holes inside the second flange part 3 and the flange main body 1, even if the interior thereof is hollow. At the same time, the length of the fourth groove 23 in the axial direction is greater than the length of the third groove 19 in the axial direction, which facilitates the processing process. The raw material processed in the third mold 7 is preliminarily processed in the fourth mold 8, so that the second flange part 3 is hollow and the hole inside the flange main body 1 takes shape.

[0037] Reference Figure 1 and Figure 2 The fifth mold 9 and the sixth mold 10 have the same overall structure as the fourth mold 8, and the difference lies in the change in the length of the second stretching rod 24. At the same time, the length of the second stretching rod 24 in the sixth mold 10 is greater than the length of the second stretching rod 24 in the fifth mold 9. At the same time, the first stretching rod 20 is not set in the sixth mold 10. The second stretching rod 24 in the sixth mold 10 can penetrate the raw material to form a completed flange.

[0038] The implementation principle of a flange for a hose and its processing mold in an embodiment of the present application is as follows: the raw material passes through a first mold 5, a second mold 6, a third mold 7, a fourth mold 8, a fifth mold 9, and a sixth mold 10 in sequence, and the flange main body 1 and the first flange part 2 are initially formed in the first mold 5, and the flange main body 1, the first flange part 2 and the second flange part 3 are initially formed in the second mold 6; in the third mold 7, the interior of the first flange part 2 is punched to make the interior of the first flange part 2 hollow; in the fourth mold 8, the second flange part 3 and the flange main body 1 are initially punched; in the fifth mold 9, the second flange part 3 and the flange main body 1 are punched for a second time; in the sixth mold 10, the second flange part 3 and the flange main body 1 are continuously punched to form a completed flange, that is, the interior of the flange is hollow.
