[0039] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited do not limit the present utility model.

[0040] Embodiment 1

[0041] Referring to Figure 1 As shown, the present utility model discloses a rolling device, including: a connecting rod 1, a mounting seat 2 and a hemming assembly 3. One end of the connecting rod 1 is connected to the mounting seat 2, and the other end of the connecting rod 1 is used for connecting a driving device. The mounting seat 2 is a polyhedron structure, which has at least one mounting end face and three mounting side faces. Among them: the end face is used for connecting with the connecting rod 1, and the three side faces are all used for connecting with the hemming assembly 3. The hemming assembly 3 is arranged on different mounting side faces. A hemming wheel 31 is arranged on each hemming assembly 3, and the hemming wheels 31 on each hemming assembly 3 have different structures. The hemming wheels 31 with different structures are respectively applied to different rolling scenarios; in the actual rolling process, the hemming wheels 31 with different structures can be used to perform rolling forming treatment on sheet metal parts with different shapes, meeting various rolling requirements. Compared with the existing rolling equipment, it is not necessary to frequently replace the rolling head, which can improve the efficiency of the rolling process, and can also ensure that the rolling equipment can be used stably for a long time without the assembly structure becoming loose due to frequent disassembly.

[0042] Referring to Figure 2 As shown, in this embodiment, the mounting seat 2 is a hexahedron structure. The mounting seat 2 has two oppositely arranged mounting end faces 21. Four mounting side faces 22 are arranged between the two mounting end faces 21. Among them: one mounting end face 21 is connected to the connecting rod 1, and three mounting side faces 22 are respectively connected to three hemming assemblies 3 provided with different hemming wheels 31, and the remaining one mounting side face 22 is reserved as a spare mounting side face 22.

[0043] Specifically, mounting holes 23 are provided on the mounting side surface 22. Both the connecting rod 1 and the hemming assembly 3 are detachably assembled into the mounting holes 23 through bolts. According to actual usage requirements, the forms of the hemming assembly 3 and the connecting rod 1 can be replaced. Additionally, the mounting holes 23 on one of the mounting side surfaces 22 serve as spare holes. When not in use, the spare holes are blocked, and when in use, the hemming assembly 3 can be directly assembled into the spare holes.

[0044] During actual use, axial positioning of the hemming device is required first. Therefore, one mounting end face 21 in this embodiment is connected to the connecting rod 1, and a positioning member 4 is correspondingly provided on the other mounting end face 21. Referring to Figure 3 as shown, the positioning member 4 has a connecting flange 41 and a positioning shaft 42. The connecting flange 41 is provided on the mounting end face 21, and the positioning shaft 42 protrudes from the connecting flange 41. The positioning shaft 42 and the connecting rod 1 are coaxially arranged. During use, axial positioning of the positioning shaft 42 is equivalent to axial positioning of the connecting rod 1, thereby being able to determine that the hemming device can output an axial driving force.

[0045] Referring to Figure 4 as shown, the hemming assembly 3 not only includes a hemming wheel 31, but also includes: a hemming shaft 32, a hemming bearing 33, and a hemming wheel fixing cover 34. Among them: the hemming shaft 32 can pass through the mounting holes 23 provided on the mounting base 2, the hemming bearing 33 is sleeved outside the hemming shaft 32, the hemming bearing 33 can rotate relative to the hemming shaft 32, the hemming wheel 31 is sleeved outside the hemming bearing 33 and can rotate with the hemming bearing 33, the hemming wheel 31 can complete the hemming action, and the hemming wheel fixing cover 34 is sleeved outside the hemming shaft 32 to block the hemming wheel 31 and prevent the hemming wheel 31 from axially falling off.

[0046] Specifically, in this embodiment, the hemming wheel 31 is an inclined surface hemming wheel 311, and the inclined surface hemming wheel 311 has a protruding hemming step, and an inclined surface is provided between the hemming step and the body of the hemming wheel 31.

[0047] Referring to Figure 5 as shown, in a use scenario, the inclined surface hemming wheel 311 can be used to bend a sheet metal part with a certain inclination angle. In this embodiment, the inclined surface hemming wheel 311 bends the sheet metal part by 90°, so that the sheet metal part is wrapped outside the right angle of the product.

[0048] Referring to Figure 6As shown, in another usage scenario, by using the beveled hemming wheel 311, it is also possible to emboss a groove on a flat sheet metal part. During the rolling process, the pressure exerted by the beveled hemming wheel 311 on the surface of the sheet metal part can be gradually increased. After rolling along the trajectory 2 to 3 times, only one groove is formed on the sheet metal.

[0049] Referring to Figure 7 As shown, the hemming assembly 3 also includes: a hemming wheel 31, a hemming shaft 32, a hemming bearing 33, and a hemming wheel fixing cover 34, where: the hemming wheel 31 is a convex hemming wheel 312, and the convex hemming wheel 312 has an inclined hemming peripheral surface.

[0050] Referring to Figure 8 As shown, in one usage scenario, by using the convex hemming wheel 312, it is possible to bend a flat sheet metal part. In this embodiment, the convex hemming wheel 312 is used to roll the protruding part of the sheet metal part outside the product, so that the edge part of the sheet metal part is bent and deformed.

[0051] Referring to Figure 9 As shown, the hemming assembly 3 also includes: a hemming wheel 31, a hemming shaft 32, a hemming bearing 33, and a hemming wheel fixing cover 34, where: the hemming wheel 31 is a flat hemming wheel 313, the flat hemming wheel 313 has a smooth hemming peripheral surface, and the flat hemming wheel 313 is a relatively conventional hemming wheel 31. In one usage scenario, by using the flat hemming wheel 313, it is possible to flatten a flat sheet metal part.

[0052] Embodiment 2

[0053] In order to be able to drive the rolling device of the above Embodiment 1, referring to Figure 10 As shown, this embodiment discloses a floating rolling device, which includes the above rolling device, and further includes: a floating device 5. The floating device 5 is connected to the connecting rod 1 of the rolling device, and the floating device 5 drives the rolling device along the axial direction to apply a constant rolling pressure.

[0054] Referring to Figure 11 As shown, the floating device 5 includes: a floating device bracket 51, a module slider 52, a floating part 53, and an EHA electro-hydraulic linear drive device 54, where: the floating part 53 is connected to the floating device bracket 51 through the module slider 52. The module slider 52 includes: a slide rail and a slider. The slide rail is fixed on the floating device bracket 51; the slider is fixed on the floating part 53. One end of the EHA electro-hydraulic linear drive device 54 is connected to the floating device bracket 51, and the other end is connected to the floating part 53;

[0055] Under the driving action of the EHA electro-hydraulic linear driving device 54, the floating part 53 can perform a limited linear motion along the track. By using the EHA electro-hydraulic linear driving device 54 of this embodiment to control the rolling device, the hemming wheel 31 of the rolling device can apply equal (or nearly equal) rolling pressure to the sheet metal surface when rolling the sheet metal plane or suddenly turning to roll a pit with a certain depth.

[0056] Specifically, the specific structure of the floating device 5 and the control method of the driving force of the EHA electro-hydraulic linear driving device 54 have been disclosed in other patents applied by the company. Since the inventive point of this application lies in the rolling device, the specific structure of the floating device 5 and the control method of the driving force of the EHA electro-hydraulic linear driving device 54 will not be elaborated here one by one.

[0057] Referring to Figure 12 As shown, the floating rolling equipment further includes a driving mechanism 6. The driving mechanism 6 drives the floating device 5 to move freely in multiple directions and at multiple angles in space. In this embodiment, the driving mechanism 6 is a multi-axis robot arm. In other embodiments, the driving mechanism 6 can also be set as a multi-axis transfer table, as long as it can drive the floating device 5 to move freely in multiple directions and at multiple angles in space, so that the rolling device can complete the rolling process at multiple angles and multiple positions.

[0058] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
