Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plate rolling processing, in particular to a hydraulic two-roller automatic plate rolling machine. Background Art
[0002] A plate rolling machine is a device used to bend and roll metal sheets, and is widely used in the sheet metal processing industry. Its main function is to continuously bend the sheet metal at three points using work rollers to form workpieces into various shapes, such as cylindrical and conical.
[0003] Traditional plate rolling machines are generally classified into two types: three-roller and four-roller, based on the number and position of the rollers. Three-roller plate rolling machines are further divided into symmetrical and asymmetrical types. In a symmetrical three-roller plate rolling machine, the upper roller moves vertically and symmetrically between the two lower rollers. A screw-nut worm drive generates rotational motion between the two lower rollers, providing torque for rolling the plate. Asymmetric three-roller plate rolling machines bend the edges of the plate by adjusting the position of the upper and lower rollers and side rollers, reducing the remaining straight edge length. Four-roller plate rolling machines add a side roller, eliminating the need for turning and bending, and enabling more complex rolling processes.
[0004] However, for the operation of rolling thin plates with small diameter, the traditional plate rolling machine is extremely bulky due to its heavy structure, inconvenient operation, and difficult to control the accuracy. It requires multiple rolling to form a circle, and the work efficiency is low during mass production.
[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a hydraulic two-roller automatic plate rolling machine to solve the above problems.
[0006] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be assumed that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the present invention. Utility Model Content
[0007] In order to overcome the deficiencies in the above-mentioned prior art, the purpose of this utility model is to disclose a hydraulic two-roller automatic plate rolling machine for solving the problems of difficult precision control and low production efficiency in the cylindrical rolling operation of thin plates and small diameter plates.
[0008] The utility model discloses a hydraulic two-roller automatic plate rolling machine, comprising a frame on which a rigid roller is detachably mounted. The bending degree of the plate can be controlled by replacing the rigid rollers with different diameters. A flexible roller is provided directly below the rigid roller. The diameter of the flexible roller is larger than that of the rigid roller. Both ends of the flexible roller are slidably connected to the frame in a vertical direction. A lifting cylinder is provided below the flexible roller. The lifting cylinder is controlled by a hydraulic system. The output end of the lifting cylinder can push the flexible roller to move in a vertical direction. A drive mechanism is connected to one side of the flexible roller. The drive mechanism drives the flexible roller to rotate, and the extrusion deformation of the flexible roller provides torsional force and sufficient torque for rolling the plate.
[0009] The preferred technical solution: One end of the rigid roller is directly rotatably connected to the frame, and the other end is detachably connected to the frame via a fastening device. The fastening device includes a flap rotatably connected to the rigid roller and a tilting cylinder. The flap is rotatably connected to the frame, with its rotation axis perpendicular to the axis of the rigid roller. One end of the tilting cylinder is hinged to the frame, and the other end is hinged to the side of the flap away from the rigid roller. The tilting cylinder is controlled by a hydraulic system. The hydraulic system controls the flap to quickly replace the rigid roller on the frame, improving operational efficiency.
[0010] Preferred technical solution: The flexible roller includes a steel roller core, and the outer surface of the steel roller core is covered and fixed with a rubber layer. The surface wear resistance of the steel roller core is higher than that of general materials and will not cause damage to the surface of the plate.
[0011] The preferred technical solution: Bearing seats are installed at both ends of the flexible roller. Lower roller bearing guide rails are installed vertically at the corresponding positions on the frame. The bearing seats are slidable up and down within the lower roller bearing guide rails. The output end of the lifting cylinder is vertically connected to the bearing seats. This ensures the movement accuracy of the flexible roller, thereby improving the accuracy of sheet metal rolling.
[0012] The preferred technical solution is as follows: the driving mechanism includes a servo motor, the output end of the servo motor is connected to a reducer, the output end of the reducer and the shaft end of the flexible roller are provided with sprockets, and the sprockets are connected by a chain to ensure the power output stability and controllability of the driving mechanism.
[0013] Optimal technical solution: A chain tensioning device is further provided on the frame, and the output end of the chain tensioning device abuts against the side of the chain, ensuring a stable connection for power transmission to the flexible roller after it is raised or lowered.
[0014] Preferred technical solution: The servo motor and hydraulic system adopt PLC control to improve the degree of automation and thus improve processing efficiency.
[0015] Preferred technical solution: A feeding platform is also provided on the machine frame to assist in positioning and feeding the plates, thereby improving processing efficiency.
[0016] Due to the application of the above technical solution, the present invention has the following beneficial effects compared with the prior art:
[0017] The utility model relates to a hydraulic two-roller automatic plate rolling machine, which rolls plates by adopting a flexible roller with a large diameter and a rigid roller with an adjustable diameter. During the processing, the deformation elastic force of the flexible roller is used as the force for bending the plate, and the curvature of the plate is adjusted by replacing rigid rollers with different diameters. The utility model has a simple structure, high processing efficiency and precision. At the same time, the flexible roller can avoid damaging the surface of the plate, thereby improving the surface quality of the rolled plate product. The hydraulic system is adopted to ensure that the pressure provided by the flexible roller is large enough and the output is uniform, so that the rolling precision of the plate is more stable. The use of PLC for control makes the operation simpler and improves the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0030] Example 1:
[0031] like Figure 1As shown, the present invention discloses a hydraulic two-roller automatic plate rolling machine, comprising a frame 1, a rigid roller 2 detachably provided on the frame 1, and a flexible roller 3 directly below the rigid roller 2. The main components of the present invention will be described in detail below:
[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, the frame 1 includes a base plate, with a left side plate 1b and a right side plate 1c welded to the base plate 1a, parallel to each other. The left and right sides 1b and 1c are parallel to the base plate 1a. The right side plate 1c is provided with a fastening device 11. The fastening device 11 includes a flap 11a rotatably connected to the rigid roller 2 and a tilting cylinder 11b. The flap 11a is rotatably connected to the upper end of the right side plate 1c, with its rotation axis perpendicular to the axial direction of the rigid roller 2. The tilting cylinder 11b is hinged at one end to the base plate 1a and at the other end to the side of the flap 11a away from the rigid roller 2. The tilting cylinder 11b is controlled by a hydraulic system 6. A right lower roller bearing sliding guide 12 is welded to the left and right sides 1b and 1c. The lower roller bearing sliding guide 12 is vertically arranged below the mounting position of the rigid roller 2. It should be noted that the base plate 1a, the left side plate 1b, and the right side plate 1c are merely exemplary structures of the frame 1 and are not intended to be limiting.
[0033] like Figure 1 、 Figure 2 and Figure 3 As shown, the left end of the rigid roller 2 is rotatably connected to the left side plate 1b of the frame 1, and the other end is detachably connected to the right side plate 1c of the frame 1 through a fastening device 11. The curvature of the material sheet can be changed by replacing the rigid roller 2 with different diameters.
[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, the diameter of the flexible roller 3 is larger than that of the rigid roller 2. Bearing seats 33 are provided at both axial ends of the flexible roller 3. The bearing seats 33 are slidably arranged in the lower roller bearing sliding guide rail 12. A lifting cylinder 4 is provided below the flexible roller 3. The lifting cylinder 4 is controlled by a hydraulic system 6. The output end of the lifting cylinder 4 is arranged in the vertical direction and is connected to the bearing seat 33 to push the flexible roller 3 to move in the vertical direction. A driving mechanism 5 is connected to one side of the flexible roller 3 to rotate the flexible roller 3.
[0035] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the usage and principle of the utility model are as follows: when working, the hydraulic system 6 is controlled by the electrical control cabinet 7 to start providing pressure for the turning cylinder 11b, and then the fastening device 11 is controlled to limit the rigid roller 2 to be installed on the frame 1, and then the hydraulic system 6 is controlled by the electrical control cabinet 7 again to provide pressure for the lifting cylinder 4, so that it pushes the flexible roller 3 to press against the rigid roller 2, so that the flexible roller 3 produces a certain deformation, and the plate is sent between the flexible roller 3 and the rigid roller 2, and then the driving mechanism 5 is controlled by the electrical control cabinet 7 to drive the flexible roller 3 to rotate, and then drive the plate to move between the flexible roller 3 and the rigid roller 2. In this process, since the diameter of the flexible roller 3 is larger than the diameter of the rigid roller 2, the elastic force generated by the deformation of the flexible roller 3 can make the plate bend toward the side of the rigid roller 2, and finally form a cylinder. After the cylindrical plate is formed, the hydraulic system 6 is controlled by the electrical control cabinet 7 to make the turning cylinder 11b open the fastening device 11 and the lifting cylinder 4 descend, and then the material can be unloaded.
[0036] Example 2:
[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, in order to improve the durability of the flexible roller 3, the flexible roller 3 adopts a structural design of an internal steel roller core 31 and an externally covered fixed rubber layer 32. The rubber layer 32 has good wear resistance and can ensure the dimensional stability of the flexible roller 3.
[0038] Example 3:
[0039] like Figure 1 、 Figure 2 and Figure 3 As shown, in order to improve the output stability of the flexible roller 3, the driving mechanism 5 adopts a servo motor 51 as the power output to ensure the controllability of the output. The output end of the servo motor 51 is connected to the reducer 52. A sprocket is set between the output end of the reducer 52 and the shaft end of the flexible roller 3. The sprockets are connected by a chain 53. The output stability is ensured by the reducer 52. The sprocket and the chain 53 cooperate to ensure the stability of the power transmission. A chain tensioning device 13 is also provided on the frame 1. The output end of the chain tensioning device 13 abuts against the side of the chain 53 to prevent the chain 53 from falling off during the lifting and lowering of the flexible roller 3, causing power transmission failure.
[0040] Example 4:
[0041] like Figure 1 、 Figure 2 and Figure 3 As shown, in order to improve the production efficiency of the plate rolling machine, the servo motor 51 and the hydraulic system 6 are uniformly controlled by the electrical control cabinet 7 equipped with PLC, so that the plate rolling machine can operate automatically and continuously, thereby improving the degree of automation of the plate rolling machine and further improving the processing efficiency of the plate rolling machine.
[0042] Embodiment 5:
[0043] like Figure 1 、 Figure 2 and Figure 3 As shown, in order to further improve the processing efficiency of the plate rolling machine, a feeding platform 14 is further provided on the frame 1 to assist in the feeding and positioning of the material plate.
[0044] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
