Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1

[0022] Please see attached Figure 1-3 , a tool for making a special-shaped roller sleeve, comprising:

[0023] Telescopic oil cylinder 1, U-shaped frame 2, rotating shaft 3, adjusting component 4, special-shaped mold 5 and annular partition 6, one end of the oil cylinder 1 is fixedly connected to the U-shaped frame 2, the rotating shaft 3 is detachably connected to the inner side of the notch of the U-shaped frame 2, and one end of the rotating shaft 3 passes through the annular partition 6, the special-shaped mold 5 and the adjusting component 4 in sequence and is movably connected to them respectively.

[0024] During specific use, the rotating shaft 3 is removed from the U-shaped frame, and the annular partition 6 is first installed to the stepped edge 30. Then, a suitable annular position limiting plate 60 is selected and installed according to the special-shaped roller sleeve to be processed, and then the special-shaped mold 5 and the adjustment component 4 are installed. After the threaded inner cylinder 40 is threadedly connected, the position of the retaining ring 42 is changed by changing the position of the outer cylinder 41, so that the retaining ring 42 is abutted against the special-shaped mold 5. In this way, the position of the special-shaped mold is fixed, and finally the overall position is slowly changed by the telescopic cylinder 1, so that the special-shaped mold 5 gradually approaches the processing to be processed and processes it into a predetermined shape.

[0025] Specifically, the rotating shaft 3 is provided with a stepped edge 30 and a thread 31, and the thread is located at the end of the rotating shaft 3 away from the stepped edge 30; the thread 31 and the stepped edge 30 can be regarded as the two ends of the length of the rotating shaft 3 to be used, which are the upper limit of the entire processable range.

[0026] Specifically, the adjustment component 4 includes a threaded inner cylinder 40, an outer cylinder 41 and a retaining ring 42, the threaded inner cylinder 40 is threadedly connected to the rotating shaft 3, the outer cylinder 41 is movably connected to the threaded inner cylinder 40, and the retaining ring 42 is fixedly connected to the end of the outer cylinder 41 close to the special-shaped mold 5; the position of the threaded inner cylinder 40 is fixed by the threaded connection between the threaded inner cylinder 40 and the thread 31, and the position of the outer cylinder 41 is changed by the movably connected outer cylinder 41 and the threaded inner cylinder 40, thereby changing the position of the retaining ring 42 to achieve clamping of the special-shaped mold 5.

[0027] Specifically, at least one group of first locking pins 410 are provided on the outer cylinder 41, and the first locking pins 410 penetrate the side wall of the outer cylinder 41 and contact the threaded inner cylinder 40, and the first locking pins 410 are threadedly connected to the outer cylinder 41; the outer cylinder 41 and the threaded inner cylinder 40 are adjusted in a sliding manner, and the outer cylinder 41 with the adjusted position is fixed by setting the first locking pins 410. It is worth noting that the outer cylinder 41 and the threaded inner cylinder 40 can also be fixed by threaded connection.

[0028] Specifically, an annular position limiting plate 60 is provided between the annular partition plate 6 and the special-shaped mold 5 .

[0029] Specifically, the annular partition 6 is provided with a plurality of specifications with different thicknesses, and the annular position limiting plate 60 is provided with a plurality of specifications with different outer diameters; the annular partition 6 is located at the stepped edge 30, and its purpose of setting is not only to avoid the situation that the special-shaped mold 5 cannot be fixed when the span of the stepped edge 30 is not enough, but also to adjust the position of the special-shaped mold 5 by adopting annular partitions 6 of different thicknesses, and the annular position limiting plate 60 arranged between the annular partition 6 and the special-shaped mold 5 adopts a larger diameter setting to ensure that the relative position of the special-shaped mold 5 is consistent with the workpiece to be processed. Of course, the relative position of the two can also be ensured by directly measuring with a ruler on the outside. Whether to use it can be adjusted according to one's own needs.

[0030] Embodiment 2

[0031] Please see attached Figure 4

[0032] Specifically, the special-shaped mold 5 includes two semi-cylindrical molds 50 and two groups of clamping rings 51. The two ends of the semi-cylindrical mold 50 are respectively provided with semi-annular connecting ears 500 fixedly connected thereto, and the two groups of clamping rings 51 are movably connected to the semi-cylindrical mold 50 through the semi-annular connecting ears 500.

[0033] Specifically, an arc-shaped groove 501 is provided on the semi-annular connecting ear 500, and at least one group of second locking pins 510 is provided on the retaining ring 51. One end of the second locking pin 510 passes through the side wall of the retaining ring 51 and contacts the arc-shaped groove 501, and the second locking pin 510 is threadedly connected to the retaining ring 51.

[0034] Taking into account the situation that the shaft 3 may need to be frequently disassembled to replace the special-shaped mold 5 during actual use, a special-shaped mold 5 that is easy to disassemble is designed. The special-shaped mold 5 is replaced by splicing two semicircular molds 50 and then fixing them with an outer retaining ring 51. When replacement is required, the second locking pin 510 is removed and the retaining ring 51 is withdrawn so that the semi-circular mold 50 can be removed freely. Then, molds of other sizes can be taken out and fixed with the outer retaining ring 51 to complete the replacement. During the whole process, you only need to adjust the position of the retaining ring 51 and the adjustment component 4. Compared with the traditional replacement method, the steps and difficulty are greatly reduced.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
