Description

Technical Field

[0001] This utility model relates to the field of rolling machine technology, and in particular to a steel plate rolling machine. Background Technology

[0002] A steel plate rolling machine is a mechanical device used to bend and roll steel plates into round, conical, or arc-shaped workpieces. The three-roll rolling machine is a commonly used device, which can roll steel plates by the cooperation of three rollers.

[0003] In existing technologies, common steel plate rolling machines lack convenient disassembly and assembly mechanisms, making the disassembly of the upper roller extremely cumbersome. When maintenance operations such as inspection and replacement of parts are required on the upper roller, a series of complex preparatory work must be undertaken first. Operators need to use various tools, such as wrenches and screwdrivers, to carefully remove numerous components connected to the upper roller, including but not limited to connecting bolts and fixing brackets. These components are often numerous and tightly installed, requiring a great deal of effort to remove. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a steel plate rolling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel plate rolling machine includes a support frame, lower rollers, and upper rollers. The two lower rollers are connected by a rotating mechanism. The support frame is equipped with a rotating motor connected to one of the lower rollers. The support frame has a rotating opening and a stabilizing opening. A lifting screw is provided in the rotating opening. An adjusting motor connected to the lifting screw is provided on the support frame. A nut is threaded onto the lifting screw through a limiting mechanism. A connecting frame that is rotatably connected to the upper roller is provided on the nut through an insertion mechanism. The connecting frame is installed in the rotating opening through a disassembly and assembly mechanism. A stabilizing rod is provided in the stabilizing opening. The upper roller is connected to the stabilizing rod through the connecting mechanism.

[0007] Preferably, the rotating mechanism includes two transmission gears mounted on a support frame, and the two transmission gears are connected to and mesh with two lower rollers.

[0008] Preferably, the limiting mechanism includes a limiting rod disposed within the rotating opening, the limiting rod being parallel to the lifting screw and slidingly penetrating the nut.

[0009] Preferably, the mating mechanism includes a plug block mounted on a connecting frame, and the nut has a slot corresponding to the plug block.

[0010] Preferably, the disassembly and assembly mechanism includes a limiting block installed on the connecting frame, a limiting groove corresponding to the limiting block is provided on the inner wall of the rotating port, and a disassembly and assembly port corresponding to the limiting groove and the limiting block is provided on the support frame.

[0011] Preferably, the connecting mechanism includes a stabilizing sleeve that is slidably sleeved on the stabilizing rod, and the upper roller is rotatably connected to the upper roller.

[0012] The beneficial effects of this utility model are:

[0013] 1. By adjusting the motor to drive the lifting screw to rotate, the nut moves up and down on the lifting screw. This, combined with the insert block and connecting frame, drives the upper roller to move up and down, thus facilitating the adjustment of the distance between the upper roller and the two lower rollers. This design can adapt to the rolling requirements of steel plates of different thicknesses, improving the equipment's versatility and processing flexibility.

[0014] 2. A stabilizing rod is installed inside the stabilizing port. The upper roller is connected to the stabilizing rod through a stabilizing sleeve. The stabilizing rod and the stabilizing sleeve are at a low height, which enhances the installation stability of the upper roller and helps to improve the accuracy and quality of the rolling process.

[0015] 3. When the regulating motor continues to run, causing the nut to lift the connecting frame, the limit block moves with the connecting frame to correspond with the disassembly / removal port. At this point, the stabilizing sleeve has disengaged from the stabilizing rod. The upper roller can then be moved laterally to disengage the connecting frame from the nut, and the limit block will disengage from the disassembly / removal port, thus allowing the upper roller to be disassembled relative to the lower roller. This design facilitates the inspection and maintenance of the upper roller. Furthermore, the disassembly of the upper roller does not obstruct the lower roller, which also facilitates the inspection and maintenance of the lower roller to some extent, reducing the difficulty and cost of equipment maintenance and improving the maintainability and service life of the equipment.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A steel plate rolling machine includes a support frame 1, a lower roller 2, and an upper roller 3, as shown in the figure, for a total of three rollers, forming a three-roller plate rolling machine. The two lower rollers 2 are connected by a rotating mechanism. The support frame 1 is equipped with a rotating motor 9 connected to one of the lower rollers 2. The support frame 1 has a rotating opening 5 and a stabilizing opening 7. A lifting screw 11 is located inside the rotating opening 5. An adjusting motor 6 connected to the lifting screw 11 is also located on the support frame 1. A nut 15 is threaded onto the lifting screw 11 via a limiting mechanism. A connecting frame 16, rotatably connected to the upper roller 3, is located on the nut 15 via an insertion mechanism. The connecting frame 16 is installed inside the rotating opening 5 via a disassembly and assembly mechanism. A stabilizing rod 8 is located inside the stabilizing opening 7, and the upper roller 3 is connected to the stabilizing rod 8 via the connecting mechanism.

[0025] The rotating mechanism includes two transmission gears 4 mounted on the support frame 1. The two transmission gears 4 are connected to and mesh with the two lower rollers 2. The two transmission gears 4 work together to transmit power, so that the two lower rollers 2 can rotate simultaneously after the rotating motor 9 is started.

[0026] The limiting mechanism includes a limiting rod 12 disposed within the rotation port 5. The limiting rod 12 is parallel to the lifting screw 11 and slides through the nut 15. The limiting rod 12 is parallel to the lifting screw 11, which effectively limits the nut 15 and prevents the nut 15 from rotating with the lifting screw 11.

[0027] The insertion mechanism includes a plug 17 mounted on the connecting frame 16, and a slot 18 corresponding to the plug 17 on the nut 15. When the plug 17 is in the slot 18, the connecting frame 16 moves up and down on the lifting screw 11 together with the nut 15.

[0028] The disassembly and assembly mechanism includes a limiting block 19 mounted on the connecting frame 16. The inner wall of the rotating port 5 is provided with a limiting groove 13 corresponding to the limiting block 19. The support frame 1 is provided with a disassembly and assembly port 14 corresponding to the limiting groove 13 and the limiting block 19. When the limiting block 19 moves within the limiting groove 13 and moves to correspond to the disassembly and assembly port 14, the connecting frame 16 can move horizontally and disengage from the nut 15. At this time, the stabilizing sleeve 10 has disengaged from the stabilizing rod 8.

[0029] The connecting mechanism includes a stabilizing sleeve 10 that is slidably fitted onto the stabilizing rod 8, and the upper roller 3 is rotatably connected to the upper roller 3. The stabilizing port 7 and the stabilizing rod 8 are at a relatively low height, and the installation stability of the upper roller 3 is achieved by relying on the stabilizing rod 8 and the stabilizing sleeve 10.

[0030] When this utility model is in use, two lower rollers 2 and one upper roller 3 are combined to form a three-roll plate rolling machine, which can roll steel plates into circles. When it is necessary to adjust the distance between the upper roller 3 and the two lower rollers 2, the adjusting motor 6 is started to drive the lifting screw 11 to rotate. When the lifting screw 11 rotates, the nut 15 moves up and down on the lifting screw 11, and together with the insert block 17 and the connecting frame 16, it drives the upper roller 3 to move up and down.

[0031] When this device is in use, if the adjusting motor 6 is continuously started and drives the lifting screw 11 to rotate continuously, the nut 15 will drive the connecting frame 16 to rise continuously. When the limiting block 19 moves with the connecting frame 16 to correspond with the disassembly port 14, the stabilizing sleeve 10 has disengaged from the stabilizing rod 8. At this time, the upper roller 3 can be moved laterally to make it disengage the connecting frame 16 from the nut 15, and the limiting block 19 will disengage from the disassembly port 14. At this time, the upper roller 3 can be disassembled relative to the lower roller 2. After disassembly, it is convenient to inspect and maintain the upper roller 3. At this time, the upper roller 3 no longer blocks the lower roller 2, which also facilitates the inspection and maintenance of the lower roller 2 to a certain extent.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
