Description

Technical Field

[0001] This utility model relates to the field of damping ring manufacturing, and in particular to a rolling device for processing damping rings. Background Technology

[0002] The manufacturing process of large high-temperature alloy damping rings includes blanking, bending, rolling, rounding, and inspection. During the rounding process, a rounding machine is used to round sheet metal parts with irregular cross-sections. Existing rounding machines include an upper roller with parallel axes extending horizontally and two lower rollers. When rounding damping rings of different diameters, it is necessary to adjust the horizontal distance between the two lower rollers and the vertical distance between the upper roller and the two lower rollers. In the existing technology, the horizontal distance between the two lower rollers and the vertical distance between the upper roller and the two lower rollers need to be adjusted separately. This is not only time-consuming and labor-intensive, but also results in a mismatch between the horizontal and vertical distances between the two lower rollers and the upper roller, thus affecting product quality.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a rolling device for processing damping rings according to this utility model, in conjunction with the accompanying drawings and embodiments, provides a further detailed explanation. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0035] Example 1

[0036] like Figure 1As shown, a rolling device for processing damping rings is used to roll sheet metal parts 1 into round shapes. The sheet metal parts 1 have an irregular cross-sectional shape. The rolling device includes: a frame 2, an upper roller 3, a first lower roller 4, a second lower roller 5, a drive shaft 6, a first adjusting screw 7, a first gear 8, a second gear 9, a second adjusting screw 10, a first bevel gear 11, a second bevel gear 12, a first nut 13, a second nut 14, and a third nut 15. The axes of the upper roller 3, the first lower roller 4, and the second lower roller 5 are arranged parallel to each other, and all three axes extend horizontally, so that the upper roller 3 can work together with the first lower roller 4 and the second lower roller 5 to compress the sheet metal parts 1. The first lower roller 4 and the second lower roller 5 slide on the frame 2. The first adjusting screw 7 has a first threaded section 16 and a second threaded section 17 with opposite thread directions at both ends. The first nut 13 is connected to the first lower roller 4 and is adapted to the first threaded section 16. The second nut 14 is connected to the second lower roller 5 and is adapted to the second threaded section 17. The axis of the first adjusting screw 7 extends horizontally, and the first threaded section 16 and the second threaded section 17 are threadedly connected to the first nut 13 and the second nut 14, respectively. The axis of the drive shaft 6 is parallel to the axis of the first adjusting screw 7. The first gear 8 is mounted on the drive shaft 6, and the second gear 9 is mounted on the first adjusting screw 7 and meshes with the first gear 8. The axis of the second adjusting screw 10 extends vertically, and its top end has a third threaded section 18. Its bottom end is rotatably connected to the frame 2. The third nut 15 is connected to the upper roller 3 and is threadedly connected to the third threaded section 18. The first bevel gear 11 is mounted on the drive shaft 6, and the second bevel gear 12 is mounted on the second adjusting screw 10 and meshes with the first bevel gear 11.

[0037] With this technical solution, when the drive shaft 6 rotates, the first adjusting screw 7 can be driven to rotate via the first gear 8 and the second gear 9. This, in turn, allows the first threaded section 16 and the second threaded section 17, with opposite directions of rotation, to engage with the first nut 13 and the second nut 14, respectively, thus adjusting the horizontal distance between the first lower roller 4 and the second lower roller 5. Simultaneously, when the drive shaft 6 rotates, the second adjusting screw 10 can be driven to rotate via the first bevel gear 11 and the second bevel gear 12. This, in turn, allows the third threaded section 18 to engage with the third nut 15, thus adjusting the vertical distance between the upper roller 3 and the first lower roller 4 and the second lower roller 5. This not only makes the adjustment work of the rolling equipment more convenient but also ensures the accuracy of the adjustment, thereby guaranteeing product quality.

[0038] Specifically, such as Figure 1 As shown, it also includes a drive device 19; the drive device 19 is fixedly connected to the frame 2 and is connected to the drive shaft 6 for driving the drive shaft 6 to rotate. The drive device 19 can be a variable frequency motor fixedly installed on the frame 1, but is not limited to this.

[0039] In actual work, sheet metal part 1 has a first surface (not shown) and a second surface (not shown) facing away from each other. When the upper roller 3, the first lower roller 4, and the second lower roller 5 together extrude the sheet metal part 1, the first surface is in contact with the upper roller 3, and the second surface is in contact with the first lower roller 4 and the second lower roller 5.

[0040] like Figure 2 As shown, the upper roller 3 includes a first rotating shaft 20 and a first sleeve 21. The first sleeve 21 is sleeved on the first rotating shaft 20, and the two are fixedly connected together. A groove and / or protrusion extending circumferentially and matching the shape of the first surface are provided on the outer surface of the first sleeve 21. In this way, when rolling sheet metal parts 1 with different cross-sectional shapes, only the first sleeve 23 needs to be replaced, and the entire upper roller 3 does not need to be replaced. This not only improves the adaptability of the work, but also saves maintenance costs.

[0041] Based on the same principle as the upper roller 3, the first lower roller 4 includes a second rotating shaft (not shown in the figure, but can be referenced). Figure 2 ) and the second sleeve (not shown in the figure, but can be referenced) Figure 2 The second sleeve is fitted onto the second rotating shaft, and the two are fixedly connected together. A groove and / or protrusion extending circumferentially and matching the shape of the second surface are provided on the outer surface of the second sleeve. The second lower roller 5 includes a third rotating shaft (not shown in the figure, but can be referenced). Figure 2 ) and the third sleeve (not shown in the figure, but can be referenced) Figure 2 The third sleeve is fitted onto the third rotating shaft, and the two are fixedly connected together. A groove and / or protrusion extending circumferentially and matching the shape of the second surface are provided on the outer surface of the third sleeve.

[0042] As an alternative implementation method, such as Figure 2 As shown, it also includes a first connecting component 22 and a second connecting component (not shown in the figure, but can be referred to). Figure 2 ) and the third connecting component (not shown in the figure, but can be referenced) Figure 1 The first connecting component 22 has a first hook A23 and a first hook B24 at its two ends, a first groove A25 on the first sleeve 21, and a first groove B26 on the first rotating shaft 20. The first hooks A23 and B24 are respectively engaged within the first grooves A25 and B26. This arrangement simplifies the installation and disassembly of the first rotating shaft 20 and the first sleeve 21.

[0043] Based on the same principle as the first connecting component 22, the second connecting component has a second hook A and a second hook B at both ends, a second groove A on the second sleeve, and a second groove B on the second rotating shaft. The second hook A and the second hook B are respectively engaged within the second groove A and the second groove B. The third connecting component has a third hook A and a third hook B at both ends, a third groove A on the third sleeve, and a third groove B on the third rotating shaft. The third hook A and the third hook B are respectively engaged within the third groove A and the third groove B.

[0044] In actual manufacturing, there are at least two first connecting parts 22, and these at least two first connecting parts 22 are evenly distributed along the circumference of the first sleeve 21 to ensure the firmness of the installation between the first sleeve 21 and the first rotating shaft 20. Similarly, there are at least two second connecting parts, and these at least two second connecting parts are evenly distributed along the circumference of the second sleeve. There are at least two third connecting parts, and these at least two third connecting parts are evenly distributed along the circumference of the third sleeve.

[0045] As an alternative implementation method, such as Figure 3 , 3 As shown, it also includes a first vertical shaft 27, a second vertical shaft 28, a first limiting roller 29, and a second limiting roller 30. The axes of the first vertical shaft 27 and the second vertical shaft 28 extend vertically, and their bottom ends can be movably connected to the frame 2. The first limiting roller 29 is rotatably disposed at the top of the first vertical shaft 27, and its axis extends vertically in the same direction as the axis of the first vertical shaft 27. The second limiting roller 30 is rotatably disposed at the top of the second vertical shaft 28, and its axis extends vertically in the same direction as the axis of the second vertical shaft 28. When the sheet metal part 1 is pressed by the upper roller 3 and the first lower roller 4 and the second lower roller 5, it can enter between the first limiting roller 29 and the second limiting roller 30, and its two ends abut against the first limiting roller 29 and the second limiting roller 30, respectively. By adopting this technical solution, the running path of the sheet metal part 1 can be restricted by the first limiting roller 29 and the second limiting roller 30, so as to avoid the sheet metal part 1 from deviating when the upper roller 3, the first lower roller 4 and the second lower roller 5 jointly squeeze the sheet metal part 1, thereby further ensuring the product quality.

[0046] Specifically, such as ​As shown, it also includes a third adjusting screw 31; the third adjusting screw 31 has a fourth threaded section 32 and a fifth threaded section 33 with opposite thread directions at both ends; a first threaded hole 34 matching the fourth threaded section 32 is provided on the first vertical shaft 27, and a second threaded hole 35 matching the fifth threaded section 33 is provided on the second vertical shaft 28. The axes of the first threaded hole 34 and the second threaded hole 35 coincide and extend in the horizontal direction. The fourth threaded section 32 and the fifth threaded section 33 are respectively threaded into the first threaded hole 34 and the second threaded hole 35. With this technical solution, the distance between the first limiting roller 29 and the second limiting roller 30 in the horizontal direction can be adjusted by rotating the third adjusting screw 31.

[0047] Example 2

[0048] A damping ring production system includes the rolling equipment described in Embodiment 1. The specific production process is as follows: first, a flat sheet is cut to the required dimensions using a cutting device; then, the flat sheet is folded into a Z-shaped sheet metal part using a bending device; next, the Z-shaped sheet metal part is rolled into a sheet metal part with an irregular cross-sectional shape as described in Embodiment 1 using a rolling device; finally, the sheet metal part with the irregular cross-sectional shape is rolled into a cylindrical shape using the rolling equipment described in Embodiment 1, thus realizing the production of the damping ring. It should be noted that the cutting device, bending device, and rolling device are not the inventive points of this utility model, but rather existing technologies. This utility model merely utilizes these existing technologies and does not intend to improve upon them; therefore, their working principles and processes will not be described in detail here.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
