Description

Technical Field

[0001] This utility model relates to a plate rolling machine, specifically a plate rolling machine with a pre-bending function. Background Technology

[0002] In many mechanical processing and manufacturing industries, plate rolling machines are indispensable. During the operation of three-roll bending, from start to finish, a long section of material at both ends is not subjected to bending moment, typically 10 to 20 times the plate thickness. A search revealed that patent CN 103894457 B discloses a plate rolling machine with a pre-bending function. This machine includes a three-roll symmetrical plate rolling machine, a plate, and a pre-bending device. The pre-bending device is fixedly installed on the three-roll symmetrical plate rolling machine, positioned between the upper and lower rollers. The plate is placed on the pre-bending device for processing. A raised strip is fixedly positioned on the outer side of the bottom of the upper roller, between the axes of the two lower rollers. During operation, the pre-bending device is first assembled, and then the plate is placed on it, undergoing multiple rolls within the allowance range on one side.

[0003] After investigation and analysis, the patent has the following drawbacks in actual use: In this patent, the pre-bending device of the plate rolling machine needs to be installed manually between the upper and lower rollers, which is inconvenient to operate. When the bending pad starts rolling, it needs to be manually installed into the plate rolling machine. The pre-bending device has a limited pre-bending angle during pre-bending and does not have a better pre-bending effect.

[0004] In summary, this application proposes a plate rolling machine with pre-bending function to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a plate rolling machine with a pre-bending function to solve the problems in the patent, which require manual installation of the pre-bending device between the upper and lower rollers, making operation inconvenient. When the bending pad is started, it needs to be manually installed into the plate rolling machine. The pre-bending device has a limited pre-bending angle and does not have a better pre-bending effect.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a plate rolling machine with pre-bending function is as follows: A plate rolling machine with pre-bending function includes a base plate, an upper roller assembly, a first lower roller, and a second lower roller. The upper roller assembly is mounted on the base plate via an electric push rod. A frame drive motor is mounted on the top of the electric push rod. The first and second lower rollers are mounted on the base plate. The upper roller assembly contains multiple sets of upper rollers of different sizes. The upper rollers are rotatably connected to the rotating shaft of the upper roller drive motor via a frame. The upper roller drive motor is fixedly mounted on the frame. A lifting platform is fixedly mounted on the base plate.

[0007] Preferably, each of the multiple sets of upper rollers in the upper roller device is equipped with an upper roller drive motor.

[0008] Preferably, the bottom of the electric actuator is detachably mounted on the base plate.

[0009] Preferably, the first and second lower rollers are rotatably mounted on the base plate via a bracket.

[0010] Preferably, both the first and second lower rollers are driven by a lower roller drive motor, which is fixedly mounted on the base plate by a pad.

[0011] Preferably, the lifting platform is positioned below the upper roller and between the first and second lower rollers.

[0012] Preferably, the top of the lifting platform is curved.

[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, in this utility model, it is only necessary to place the coil plate to be pre-bent between the upper and lower rollers, and the lifting platform can be controlled to automatically perform pre-bending, which is safe and convenient. Different pre-bending angles can be provided by adjusting different sizes of the upper roller, resulting in better pre-bending effect. Attached Figure Description

[0015] 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 scope of protection of the present utility model.

[0016] Please see Figure 1-4This utility model provides a technical solution: a plate rolling machine with pre-bending function, including a base plate 1, an upper roller device 2, a first lower roller 3 and a second lower roller 4. The upper roller device 2 is installed on the base plate 1 by an electric push rod 6. The electric push rod 6 can drive the upper roller device 2 to move up and down. A frame drive motor 10 is installed on the top of the electric push rod 6 to control the rotation of the frame 21 and control different rolling angles for plate rolling.

[0017] To further explain, the first lower roller 3 and the second lower roller 4 are mounted on the base plate 1 and work in conjunction with the frame plate 21. The upper roller device 2 has multiple sets of upper rollers 22 of different sizes to provide different rolling angles. The upper roller 22 is rotatably connected to the rotating shaft of the upper roller drive motor 23 through the frame plate 21. The upper roller drive motor 23 is fixedly mounted on the frame plate 21, thereby realizing the operation of the upper roller 22.

[0018] When the sheet material needs to be rolled, in order to roll the sheet material under the upper roller 22, a lifting platform 8 is fixedly installed on the base plate 1. The lifting platform 8 is located below the upper roller 22 and between the first lower roller 3 and the second lower roller 4. By controlling the height of the lifting platform 8, the sheet material is squeezed tightly against the upper roller 22 for rolling.

[0019] To further explain, the top of the lifting platform 8 is arc-shaped to cooperate with the operation of the upper roller 22. The multiple sets of upper rollers 22 in the upper roller device 2 are each equipped with an upper roller drive motor 23. When small-sized plates need to be rolled, the upper roller 22 and the first lower roller 3 can be used to roll the plates together.

[0020] The bottom of the electric push rod 6 can be detachably mounted on the base plate 1. In practical applications, a spiral push rod can be installed on one side of the electric push rod 6 to control the left and right movement of the upper roller device 2 to cooperate with the lower roller.

[0021] More specifically, in order for the lower roller to work in conjunction with the upper roller, the first lower roller 3 and the second lower roller 4 are rotatably mounted on the base plate 1 via the bracket 9. Both the first lower roller 3 and the second lower roller 4 are driven by a lower roller drive motor 5, which is fixedly mounted on the base plate 1 via a pad 7.

[0022] Please refer to the following instructions for specific usage. When it is necessary to roll the sheet metal, the control frame drive motor 10 is rotated to adjust the rotation of the frame 21. Different rolling angles are selected for rolling. The rolled sheet is pushed from above the first lower roller 3 and below the upper roller 22 to above the lifting platform 8. The upper roller drive motor 23 and the lower roller drive motor 5 are started, causing the upper roller 22, the first lower roller 3 and the second lower roller 4 to rotate. The electric push rod 6 is controlled to drive the upper roller device 2 to move up and down. At the same time, the lifting platform 8 is controlled to move up and down. The two work together to make the rolled sheet tightly adhere to the upper roller 22 on the lifting platform 8, thereby rolling the sheet metal.

[0023] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
