Description

Technical Field

[0001] The present invention relates to a rolling device, and more particularly to a rolling device which can absorb the tolerance and backlash caused by the assembly of various components transmitted from a machine body to two rollers, thereby maintaining a set gap between the two rollers to improve the rolling precision. Background Art

[0002] The rolling device includes cold pressing or hot pressing, which mainly uses two rollers to roll a workpiece so that the workpiece can be kept at a thickness with optimal precision.

[0003] Most of the aforementioned rolling devices are to install two rollers on a machine body. Some rolling devices will fix one roller on the machine body, while the other roller can be displaced on the machine body, so that the gap between the two rollers can be adjusted on the machine body. Another part of the rolling devices is to install both rollers on the machine in a movable manner, so that the gap between the two rollers can be adjusted by adjusting the position of the two rollers.

[0004] Most of the aforementioned rolling devices have the same problem, that is, there are tolerances and backlashes between the various parts on the machine body. When the assembly is completed, the accumulated tolerances between the various parts will be transferred to the gap between the two rollers, so that after the gap between the two rollers is set, when the workpiece enters between the two rollers for rolling, the two rollers will be affected by the reaction force generated by the workpiece, so that the tolerances between the various parts are magnified and the position of the backlash moves, so that the gap between the two rollers cannot be effectively maintained at the set gap value, thereby making the accuracy of each workpiece after passing through the rolling device unstable, thereby affecting the subsequent processing and accuracy of the workpiece.

[0005] Therefore, how to provide a roller device that can absorb the tolerances of the above-mentioned parts so that the gap between the two rollers is effectively maintained is the problem to be solved in this case. Summary of the invention

[0075] In order to further understand the techniques, means and effects adopted by the present invention to achieve the predetermined objectives, preferred feasible embodiments are now given as examples and described in detail with reference to the accompanying drawings. It is believed that the objectives, features and advantages of the present invention can be understood in depth and in detail.

[0076] like Figures 1 to 11 As shown, the present invention provides a rolling device 10 , which includes a machine body 20 , two rollers 30 and two elastic return units 40 .

[0077] In this embodiment, the machine body 20 has a base 21. In this embodiment, in order to enable the two rollers 30 to roll effectively on the machine body 20, a first bearing seat 22, a cantilever set 23, and a second bearing seat 24 are respectively provided on two corresponding sides of the base 21 relative to the two rollers 30. The two first bearing seats 22 are directly fixed on the base 21, the two cantilever sets 23 are also fixed on the base 21, and the second bearing seat 24 is fixed on the cantilever set 23. Each cantilever set 23 includes a support arm 231 fixed on the base 21, a swing arm 232 swingable on the support arm 231, and a screw set 233 for adjusting the angle of the cantilever, and each screw set 233 includes a fixed seat 2331 fixed on the base 21, a screw 2332 extending from the fixed seat 2331, and a starting unit 2333 connected to the swing arm 232. Each of the second bearing seats 24 is fixed on each of the swing arms 232 and is opposite to the first bearing seat 22 .

[0078] Two rollers 30 are respectively mounted on the machine body. In this embodiment, the two rollers 30 include a first roller 31 and a second roller 32. The center of the first roller 31 has a first axis 311, which extends outward from two corresponding sides of the first roller 31 and is respectively penetrated on each of the first bearing seats 22. The center of the second roller 32 has a second axis 321, which extends outward from the corresponding sides of the second roller 32 and is respectively penetrated on each of the second bearing seats 24. A gap is formed between the first roller 31 and the second roller 32. In this way, each swing arm 232 can be driven by the starting unit 2333, and swings on the base 21 with the support arm 231 as the center, thereby driving the second roller 32, and then adjusting the gap size between the first roller 31 and the second roller 32.

[0079] The two elastic return units 40 are respectively installed on the two corresponding sides of the first axis 311 and the second axis 321, and each elastic return unit 40 has an elastic module 50 and a supporting module 60. In this embodiment, the elastic module 50 is arranged on the first axis 311, and the supporting module 60 is arranged on the second axis 321. Each elastic module 50 further includes a first connecting seat 51 and a spring module 52, and the first connecting seat 51 includes at least one first bearing sleeve 511 arranged on the first axis 311 and a first pressure plate 512 connected to the first bearing sleeve 511. However, in the present embodiment, in order to more effectively utilize the first connecting seat 51 to support the spring module 52, two first bearing sleeves 511 are arranged on the first connecting seat 51 in the present embodiment, and are respectively arranged on the first axis 311, so that the two first bearing sleeves 511 can be respectively arranged on both sides of the above-mentioned first bearing seat 22 to more effectively support the spring module 62. However, in actual application, only one first bearing sleeve 511 can be arranged, and the first bearing sleeve 511 can be arranged at the central position of the first pressure plate 512 to achieve the same effect. The spring module 52 is connected to the other side of the first pressure plate 512 and is adjacent to the abutting module 60, and each of the spring modules 52 is further composed of an upper plate 521, a lower plate 522 and a plurality of elastic elements 523. A gap is formed between the upper plate 521 and the lower plate 522, and the elastic elements 523 are arranged between the upper plate 521 and the lower plate 522, and the elastic elements 523 are pre-pressed by the upper plate 521 and the lower plate 522, so that each of the elastic elements 523 maintains an elastic restoring force.

[0080] It is worth mentioning that when each spring module 52 is installed, after the elastic elements 523 are pre-pressed by the upper plate 521 and the lower plate 522 , the elastic restoring force accumulated by the elastic elements 523 will be greater than the gravity of the first roller 311 and the second roller 321 .

[0081] Among them, the two first bearing sleeves 511 of each connecting seat 511 are respectively arranged on both sides of the first bearing seat 22 and penetrated on the first axis 311. In addition to being used to fix the two first bearing sleeves 511, the first pressure plate 512 is also fixed on the first bearing seat 22, and the spring module 52 is installed on the first pressure plate 512. At the same time, the lower plate 522 is pressed against the first pressure plate 512, and the upper plate 521 forms the distance with the lower plate 522 through the elastic elements 523, and at the same time, the upper plate 521 is able to form a displacement on the lower plate 522 through the elastic elements 523 to move up and down along the extension direction of the elastic elements 523.

[0082] Each of the abutting modules 60 is further composed of a second connecting seat 61 and at least one pulley module 62. However, in the present embodiment, two pulley modules 62 are provided in each abutting module 60, and the two pulley modules 62 are respectively provided on the left and right sides of each of the second connecting seat 61. In practical applications, the same effect can also be achieved by providing one pulley module 62. The second connecting seat 61 includes at least one set of second bearing sleeves 611 provided on the second axis 321 and a second pressing plate 612 connected to the second bearing sleeves 611. In the present embodiment, in order to match the above two pulley modules 62, two second bearing sleeves 611 are similarly configured in the present embodiment, and each of the second bearing sleeves 611 is respectively connected and fixed to each of the pulley modules 62 through the second pressing plate 612. The two pulley modules 62 are disposed on the other side of the second pressure plate 612 and are adjacent to the spring module 52. Each pulley module 62 is composed of a fixing seat 621 and a pulley 622. Each fixing seat 621 is used to connect and fix with each second bearing sleeve 611, and each pulley 622 is axially disposed on each fixing seat 621. In this embodiment, the two second bearing sleeves 611 are respectively disposed on both sides of the second bearing seat 24 and penetrate the second axis 321. In addition to fixing the two second bearing sleeves 611, the second pressure plate 612 is fixed on the second bearing seat 24. Each pulley module 62 is connected to each second bearing sleeve 611.

[0083] In this way, when the second roller 32 in this embodiment is displaced toward the first roller 31 through the starting unit 2333, the pulley modules 62 can be driven to rotate toward the spring modules 52 at the same time, so that the pulley modules 62 can gradually contact and press against the upper plate 521. As the gap between the first roller 31 and the second roller 52 gradually decreases, the pressure of the pulley modules 62 against the upper plate 521 increases, so that the upper plate 521 compresses the elastic elements 523. Since the elastic elements 523 have been pre-pressed during installation, the elastic restoring force accumulated after the elastic elements 523 are compressed (such as Fig.11 The elastic restoring force is transmitted back to the upper plate 521 and the lower plate 522 at the same time, and then the elastic restoring force is transmitted to the first axis 311 and the second axis 321 of the first roller 31 and the second roller 32 respectively, so that a reaction force (such as the first axis 311 and the second axis 321) moving away from each other is generated between the first axis 311 and the second axis 321. Fig.11 ), so that the first axis 311 and the second axis 321 are tightly pressed against the first bearing seat 22 and the second bearing seat 24, so that the predetermined gap between the first roller 31 and the second roller 32 can be effectively maintained. When the first roller 31 and the second roller 32 perform rolling operation on the aforementioned workpiece, the gap between the first roller 31 and the second roller 32 can be effectively fixed, thereby effectively improving the overall processing accuracy of the rolling device 10, thereby effectively providing a more accurate size for the thickness of the workpiece, reducing the tolerance between the workpieces, so as to maintain the subsequent processing accuracy of the workpiece.

[0084] See also Figures 12 to 20 As shown, it is a second embodiment of the present invention. In this embodiment, the elastic module 50 is installed on the second axis 321, and the abutting module 60 is installed on the first axis 311. However, in this embodiment, when the abutting module 60 is installed on the first axis 311, the second bearing sleeves 611 are mainly sleeved on the first axis 311, and the first bearing seat 22 is located between the two second bearing sleeves 611, and the second pressure plate 612 is fixed on the first bearing seat 22, and the pulley modules 62 are arranged toward the elastic module 50. When the elastic module 50 is installed on the second axis 321, the first bearing sleeve 511 is also sleeved on the second axis 321, and the first pressure plate 512 is fixed on the swing arm 232, and the spring module 52 is installed above the first pressure plate 512 and adjacent to the pulley modules 62.

[0085] The action mode of this embodiment is that when the second roller 32 is displaced toward the first roller 31 by the starting unit 2333, the elastic module 50 is driven to move toward the pulley module 62, so that the spring module 52 gradually contacts the pulley modules 62, and the spring module 62 is gradually pressed by the pulley modules 52, so that the upper plate 521 and the lower plate 522 are subjected to the elastic restoring force of the elastic elements 53 (such as Fig. 20 As shown by the double-headed arrows in the figure, the first axis 311 and the second axis 321 also generate a reaction force moving away from each other (as shown by the double-headed arrows in the figure). Fig. 20 As shown by the single arrow in the figure, the first axis 311 and the second axis 321 are tightly pressed against the first bearing seat 22 and the second bearing seat 24, so that the predetermined gap between the first roller 31 and the second roller 32 can be effectively maintained, thereby effectively improving the overall processing accuracy of the rolling device 10.

[0086] Please refer to all the accompanying drawings. It is worth mentioning that the various components of the elastic module 50 and the abutting module 60 described in the present invention are installed by screw-fixing elements of different lengths. Therefore, in actual use, the screw-fixing elements of different lengths and sizes can be installed according to different environments of use. Therefore, the elastic module 50 and the abutting module 60 can provide a reaction force between the first axis 311 and the second axis 321 that moves in a direction away from each other, thereby effectively maintaining the gap between the first axis 311 and the second axis 321.

[0087] It is worth mentioning that, since the elastic element 523 in the spring module 52 is pre-stressed during installation, when the two rollers 30 are not being processed, the structure of the entire rolling device 10 will not be affected by the elastic restoring forces, thereby increasing the structural life of the entire rolling device 10. When the present invention is applied to a device where some of the rollers need to be heated, the two rollers 30 can be rotated for a long time for preheating or for a long time for cooling, ensuring that the structure of the entire rolling device 10 will not be affected by the elastic restoring forces, thereby increasing the structural life of the entire rolling device 10. When the two rollers 30 are performing processing operations, after the gap between the two rollers 30 is pressed to a preset gap value, the entire rolling device 10 will be affected by the elastic restoring force and effectively maintain the gap between the two rollers 30. Therefore, when the elastic element 523 is pre-stressed, the elastic restoring force generated during the pre-stressing can be designed to be slightly larger than the gap value between the two rollers 30, so as to ensure that the two rollers 30 can maintain the required gap during the processing operation, so that the processing quality is more stable.
