Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, specifically to a dynamic balancing mechanism for plate rolling machine rollers. Background Technology

[0002] The function of the dynamic balancing mechanism of the plate rolling machine is to adjust the relative position of the three rollers in the plate rolling machine so that they are always in a balanced state. This can effectively avoid deviations caused by inaccurate roller positions, ensure the accuracy and quality of the plate rolling process, and make the rolled products meet the standards in terms of size and shape.

[0003] In the operation of existing plate rolling machines, the position adjustment between the rollers is crucial, as it directly affects the rolling quality and precision of the plate. However, the current adjustment mechanism has obvious defects in practical applications, making it difficult to effectively balance the positional relationship between the three rollers. Due to the lack of precise and stable adjustment capabilities, the three rollers often fail to achieve an ideal coordinated state during the adjustment process, and positional deviations are prone to occur. These deviations not only lead to problems such as irregular shape and substandard dimensions after plate rolling, but also reduce production efficiency and increase scrap rate. Therefore, we propose a dynamic balancing mechanism for the roller shafts of a plate rolling machine. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that existing adjustment mechanisms are not easy to balance the positional relationship between the three rollers.

[0005] To solve the above-mentioned technical problems, this application provides a dynamic balancing mechanism for the roller shaft of a plate rolling machine, including a disc, a first groove on one side of the disc, and two second grooves on one side of the disc, the two second grooves being respectively disposed on both sides of the first groove;

[0006] An adjustment assembly includes a rotating shaft fixedly connected inside a disc, a first rotating rod fixedly connected to the outside of the rotating shaft, a second rotating rod rotatably connected to the end of the first rotating rod, a movable plate rotatably connected to the end of the second rotating rod, the movable plate being slidably connected within a first groove, and a connecting piece provided on the outside of the movable plate.

[0007] In some embodiments, the adjustment component, the first groove, and the second groove are each configured as three groups, and all three groups are arranged around the central axis of the disk.

[0008] In some embodiments, the connector includes a frame fixedly connected to the outside of the movable plate, a slider slidably connected inside the frame, a connecting block fixedly connected to the outside of the slider, and a hydraulic rod fixedly connected outside the frame, the driving end of the hydraulic rod being fixedly connected to the slider.

[0009] In some embodiments, two auxiliary rods are fixedly connected to the bottom of the frame, and the two auxiliary rods are slidably connected to two second grooves respectively.

[0010] In some embodiments, a support plate is provided outside the disk, the disk is rotatably connected to the support plate, a first motor is fixedly connected inside the support plate, and the drive end of the first motor is fixedly connected to a rotating shaft.

[0011] In some embodiments, a gear ring is fixedly sleeved on the outside of the disk, and a second motor is disposed outside the gear ring. The second motor is fixedly connected inside the support plate, and a gear is fixedly connected to the drive end of the second motor, the gear meshing with the gear ring.

[0012] In some embodiments, an upper roller and two side rollers are fixedly connected between the two sets of connecting blocks, respectively.

[0013] This utility model has at least the following beneficial effects:

[0014] During use, two sets of opposing adjustment components synchronously drive the upper roller and the two side rollers to move. Because the three first grooves are symmetrical about the central axis, have the same length, and are spaced at the same angle, the upper roller and the two side rollers can always maintain a dynamic balance during movement, achieving precise centering movement. This dynamic balance adjustment method allows the sheet metal to be evenly stressed during rolling. Taking the rolling of a cylindrical body as an example, the deformation of each part of the sheet metal is consistent due to the uniform stress, avoiding local deformation problems such as bulging, denting, or twisting. The dynamic balance adjustment effect ensures that the rolled workpiece shape meets the design requirements and has higher dimensional accuracy. In short, this device can dynamically balance the positional relationship between the upper roller and the two side rollers. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see Figures 1-5 This utility model provides a technical solution:

[0023] A dynamic balancing mechanism for a plate rolling machine roller includes a disc 1. A first groove 2 is provided on one side of the disc 1, and two second grooves 3 are provided on one side of the disc 1. The two second grooves 3 are respectively arranged on both sides of the first groove 2. The three first grooves 2 are symmetrical about the central axis, and the three sets of second grooves 3 are also symmetrical about the central axis.

[0024] Adjustment component 4 includes a rotating shaft 41 fixedly connected inside the disc 1, a first rotating rod 42 fixedly connected outside the rotating shaft 41, a second rotating rod 43 rotatably connected to the end of the first rotating rod 42, and a movable plate 44 rotatably connected to the end of the second rotating rod 43. The movable plate 44 is slidably connected inside the first groove 2.

[0025] A connector 45 is provided on the outside of the movable plate 44. The connector 45 includes a frame 451 fixedly connected to the outside of the movable plate 44, a slider 452 slidably connected inside the frame 451, a connecting block 453 fixedly connected to the outside of the slider 452, and a hydraulic rod 454 fixedly connected to the outside of the frame 451. The driving end of the hydraulic rod 454 is fixedly connected to the slider 452. The hydraulic rod 454 drives the slider 452 to slide inside the frame 451, which can drive the two side rollers 12 to finely adjust their positions.

[0026] Two auxiliary rods 5 are fixedly connected to the bottom of the frame 451. The two auxiliary rods 5 are slidably connected to the two second grooves 3 respectively. The auxiliary rods 5 are used to assist the sliding of the moving plate 44 and enhance stability.

[0027] A support plate 6 is provided outside the disc 1. The disc 1 is rotatably connected to the support plate 6. A first motor 7 is fixedly connected inside the support plate 6. The drive end of the first motor 7 is fixedly connected to the rotating shaft 41. The first motor 7 drives the rotating shaft 41 to rotate, thereby driving the adjustment component 4 to operate.

[0028] In use, the first motor 7 is started first. The first motor 7 drives the rotating shaft 41 to rotate, which in turn drives the first rotating rod 42 to rotate. The first rotating rod 42 drives the second rotating rod 43 to rotate. The second rotating rod 43 drives the moving plate 44 to move horizontally within the first groove 2, which in turn drives the connecting piece 45 to move. The two sets of opposing adjustment components 4 can synchronously drive the upper roller 11 and the two side rollers 12 to move synchronously. Since the three first grooves 2 are symmetrical about the central axis and have the same length and the same angle, the upper roller 11 and the two side rollers 12 can move in the center, that is, the distance between the two side rollers 12 and the upper roller 11 is the same.

[0029] When the two side rollers 12 are at the same distance from the upper roller 11, the force distribution from three axes on the sheet metal during the rolling process is more uniform. Taking the rolling of a cylindrical body as an example, the uniform force makes the deformation of each part of the sheet metal consistent, which can effectively avoid local deformation caused by uneven force, such as bulging, denting or twisting defects, thereby ensuring that the rolled workpiece shape meets the design requirements and has higher dimensional accuracy. Example 2

[0030] Please see Figures 1-5 This utility model provides a technical solution:

[0031] Unlike Embodiment 1, the adjustment component 4 includes a rotating shaft 41 fixedly connected inside the disc 1, a first rotating rod 42 fixedly connected to the outside of the rotating shaft 41, a second rotating rod 43 rotatably connected to the end of the first rotating rod 42, a moving plate 44 rotatably connected to the end of the second rotating rod 43, the moving plate 44 slidably connected inside the first groove 2, a connector 45 provided on the outside of the moving plate 44, the connector 45 includes a frame 451 fixedly connected to the outside of the moving plate 44, a slider 452 slidably connected inside the frame 451, a connecting block 453 fixedly connected to the outside of the slider 452, a hydraulic rod 454 fixedly connected to the outside of the frame 451, the driving end of the hydraulic rod 454 fixedly connected to the slider 452, and two auxiliary rods 5 fixedly connected to the bottom of the frame 451, the two auxiliary rods 5 being slidably connected to two second grooves 3 respectively;

[0032] like Figure 1 and Figure 3 As shown, the connecting block 453 can be replaced with a detachable connecting structure to facilitate the removal of the upper roller 11 and the side roller 12, making it easier to unload the sheet material.

[0033] like Figure 2As shown, the second rotating rod 43 at the position of the upper roller 11 can be removed, and then the moving plate 44 and the auxiliary rod 5 at the position of the upper roller 11 can be fixed to the disc 1 with bolts of the prior art. Then, the existing driving equipment can be connected to drive the upper roller 11 to rotate, so that the upper roller 11 can be used as the driving structure of the device to roll the plate.

[0034] like Figure 2 As shown, the second rotating rod 43 at the position of the upper roller 11 can be removed, and then the movable plate 44 at the position of the upper roller 11 can be connected to a linear drive device of the prior art, which can drive the upper roller 11 to rise and fall independently, so that the upper roller 11 can be used as a structure for adjusting the curvature. Similarly, the upper roller 11 can be connected to a drive device of the prior art to drive the upper roller 11 to rotate, so that the upper roller 11 can be used as a drive structure of the device to roll the plate.

[0035] A gear ring 8 is fixedly sleeved on the outside of the disc 1. A second motor 9 is set outside the gear ring 8 and fixedly connected inside the support plate 6. A gear 10 is fixedly connected to the drive end of the second motor 9 and meshes with the gear ring 8. An upper roller 11 and two side rollers 12 are fixedly connected between the two sets of connecting blocks 453 respectively. The second motor 9 drives the gear 10 to rotate, which in turn drives the gear ring 8 to rotate, which in turn drives the disc 1 to rotate as a whole. The angle of the upper roller 11 and the two side rollers 12 can be adjusted. It should be noted that the rotation angle cannot exceed 30 degrees to avoid affecting the rolling effect.

[0036] It should be noted that when the disk 1 rotates, the drive end of the first motor 7 can rotate arbitrarily after it stops driving. Only after it starts can the drive end of the first motor 7 drive the rotating shaft 41 to rotate. Therefore, the first motor 7 will not interfere with the rotation of the disk 1.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
