The mounting frames are equipped with a moving device to adjust the position of the transmission rollers, and a driving device to drive the transmission rollers to rotate is arranged on the mounting frames. Slide rails are respectively arranged on the top of the mounting frames. This invention includes a movable plate, and by using the inclined structure of the movable plate, the front and rear gaps between the various cutting blade devices are controlled, thereby realizing the cutting of steel plates of different widths. Furthermore, the cutting blade devices are staggered left and right, which facilitates the maintenance and replacement of different cutting blade devices.

TECHNICAL FIELD

[0001] The application belongs to the technical field of steel plate processing, relates to the field of metal cutting, and in particular relates to a steel plate cutting device. BACKGROUND

[0002] Hot-rolled steel plate is a kind of steel product that is processed by heating steel to a temperature higher than its recrystallization temperature and then changing its shape, size and properties through a series of rolling processes. Unlike cold-rolled steel plates, hot-rolled steel plates are processed at high temperatures, so their surfaces are usually rough and their dimensional tolerances are large, but they have good formability and low production costs. Hot-rolled steel plates are widely used in the construction, bridge, shipbuilding, automobile manufacturing, and mechanical processing industries, and are mainly used to make structural steel, thin plates, thick plates and other products. Due to their good plasticity, strength and adaptability, hot-rolled steel plates play an important role in the global steel market.

The combined screw passes through the two movable blocks and is threadedly engaged. The adjustment motor is fixedly mounted on the top surface of one of the slide rails through a mounting plate. The output shaft of the adjustment motor is fixedly connected to one end of the combined screw.

[0010] Furthermore, the regulating motor is a servo motor.

[0011] Furthermore, the moving device includes a moving groove, several moving blocks, a limiting plate, and fastening bolts. The moving blocks are opened on opposite sides of the mounting frame. The moving groove on the front mounting frame is a through groove structure, and the moving groove on the rear mounting frame is a limiting slide groove.

All worm wheels mesh with the worm.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention provides a steel plate cutting device. The device adjusts the angle between two movable plates. Rotation of the movable plates drives a rotating shaft to move forward and backward and left and right, thereby adjusting the position of the guide blocks and the distance between adjacent guide blocks. The user adjusts the transmission rollers according to the position of the cutting device, causing them to be misaligned with the cutting device (to prevent the cutting device from contacting the transmission rollers after cutting through the steel plate). The steel plate is placed above the transmission rollers, and the drive device is activated, moving the steel plate. A lifting device moves the slide rail downward, which in turn moves the cutting device downward, allowing it to cut the steel plate. Compared to existing technologies, this invention features movable plates with an inclined structure to control the front-to-back gap between the cutting devices, enabling the cutting of steel plates of different widths. Furthermore, the left-to-right misalignment of the cutting devices facilitates maintenance and replacement of different cutting devices.

[0016] 2. The steel plate cutting device of the present invention can control the hydraulic telescopic rod to extend and retract synchronously through the hydraulic control system, thereby driving the slide rail to move up and down synchronously.

[0017] 3. In an example of the present invention, a steel plate cutting device is provided. When the cutting motor is turned on, the output shaft of the cutting motor rotates, which drives the cutting blade to rotate, thereby enabling the cutting blade to cut the steel plate. The mounting shell provides protection and facilitates the installation of the motor and the cutting blade.

[0018] 4. In an example of the present invention, a steel plate cutting device is provided. The adjusting motor is connected to a power source and turned on. The output shaft of the adjusting motor rotates, which drives the combined screw to rotate. The rotation of the combined screw drives two movable blocks to move relative to or away from each other (the front-to-back distance of the cutting device is half the distance between the two movable blocks). This, in turn, drives two movable plates to rotate, thereby adjusting the angle between the two movable plates. The threaded structure between the movable blocks and the combined screw can fix the movable plates and ensure that the hinge between the movable blocks is located in the middle position.

[0019] 5. The steel plate cutting device of the present invention, compared with other types of motors, has more precise control over speed and position and is more convenient to use.

[0020] 6. In the steel plate cutting device of the present invention, the fastening bolts are loosened, and the user can move the moving block by moving the limiting plate, thereby moving the transmission roller, so as to adjust the gap between the moving rollers. Tightening the fastening bolts can fix the limiting plate, thereby fixing the position of the transmission roller. The moving device has a simple structure and is easy to adjust.

[0021] 7. In an example of the present invention, a steel plate cutting device has a movable handle that provides a point of leverage for the user, making it easy for the user to move the limiting plate.

[0022] 8. An example of the present invention is a steel plate cutting device. When the drive motor is connected to the power supply and turned on, the output shaft of the drive motor can drive the worm gear to rotate. The rotation of the output shaft of the worm gear can be synchronized through the worm wheel, which in turn can drive the transmission roller to rotate synchronously. The drive device has a simple structure and is easy to use. Attached Figure Description

[0030] like Figures 1-3As shown, a steel plate cutting device includes two mounting frames 1, one in front and one behind. Several transmission rollers 2 are arranged between the mounting frames 1. Each mounting frame 1 is equipped with a moving device to adjust the position of the transmission rollers 2. A driving device is mounted on each mounting frame 1 to rotate the transmission rollers 2. Slide rails 3 are respectively arranged above each mounting frame 1, with their grooves facing each other. A lifting device is mounted on each mounting frame 1 to move the two slide rails 3 synchronously up and down. Several sliders are respectively arranged inside each slide rail 3. Guide frames 4 are fixedly installed between corresponding sliders, and guide blocks 5 are respectively arranged on each guide frame 4. The guide frames 4 are equipped with... The guide block 5 is an I-shaped structure located within the through slot. One guide block 5 is installed on the leftmost guide frame 4, and two guide blocks 5 are installed on the other guide frames 5. A cutting device is fixedly installed on the bottom surface of each guide block 5. Two movable plates 6 are installed above the guide frame 4. The movable plates 6 are staggered vertically and are hinged together on one side (the hinge shaft at the hinge of the movable plate 6 is fixedly connected to the top surface of the corresponding guide block 5). A rotating shaft 7 is fixedly installed on the top surface of each guide block 5. The rotating shaft 7 passes through the movable plate 6 and is rotatably connected. An adjustment device for adjusting the angle of the movable plate 6 is provided between the slide rails 3. This invention is used for cutting steel plates. An adjustment device allows for adjustment of the angle between two movable plates 6. The rotation of the movable plates 6 drives the rotating shaft 7 to move forward, backward, left, and right, thereby adjusting the position of the guide blocks 5 and the distance between adjacent guide blocks 5. The user adjusts the transmission rollers 2 according to the position of the cutting device, causing the transmission rollers 2 to be misaligned with the cutting device (to prevent the cutting device from contacting the transmission rollers 2 after cutting through the steel plate). The steel plate is placed above the transmission rollers 2, and the drive device is activated, moving the steel plate. A lifting device moves the slide rail 3 downward, which in turn moves the cutting device downward, allowing it to cut the steel plate. Compared to existing technologies, this invention features movable plates 6, whose inclined structure controls the front-to-back gap between the cutting devices, enabling the cutting of steel plates of different widths. Furthermore, the left-to-right misalignment of the cutting devices facilitates maintenance and replacement of different cutting devices.

[0031] like Figures 1-3 As shown, in a further preferred embodiment, the lifting device includes several hydraulic telescopic rods 8. The hydraulic telescopic rods 8 are controlled by a hydraulic control system to extend and retract synchronously. The fixed end of the hydraulic telescopic rod 8 is fixedly connected to the top surface of the corresponding mounting bracket 1, and the movable end of the hydraulic telescopic rod 8 is fixedly connected to the bottom surface of the slide rail 3. The hydraulic control system can control the hydraulic telescopic rods 8 to extend and retract synchronously, thereby driving the slide rail 3 to move up and down synchronously.

[0032] like Figures 1-3As shown, in a further preferred embodiment, the cutting device includes a cutting motor 9, a mounting housing 10, and a cutting blade 11. The mounting housing 10 is fixedly mounted on the bottom surface of the guide block 5, the cutting motor 9 is fixedly mounted on one side of the mounting housing 10, and the cutting blade 11 is disposed inside the mounting housing 10. One side of the mounting housing 10 is installed via a threaded structure, allowing for installation and disassembly, facilitating the installation and replacement of the cutting blade 11. The output shaft of the cutting motor 9 passes through one side of the mounting housing 10 and is rotatably connected. The cutting blade 11 is fixedly mounted on the output shaft of the cutting motor 9, installed via a clamping cover and a positioning pin. When the cutting motor 9 is turned on, the rotation of the output shaft of the cutting motor 9 drives the cutting blade 11 to rotate, thereby enabling the cutting blade 11 to cut the steel plate. The mounting housing 10 provides protection and facilitates the installation of the motor 9 and the cutting blade 11.

[0033] like Figures 1-3 As shown, in a further preferred embodiment, the adjusting device includes two movable blocks 12, a combined screw 13, and an adjusting motor 14. The combined screw 13 is formed by screws with opposite thread directions fixedly connected. The movable blocks 12 are respectively rotatably mounted on the upper ends of the corresponding two rotating shafts 7. Specifically, the rotatable mounting method is to install them through bearing connection. In this application, the combined screw 13 is set on the two middle rotating shafts 7. The combined screw passes through the two movable blocks 12 and is threadedly engaged. The adjusting motor 14 is fixedly mounted on the top surface of one of the slide rails 3 through a mounting plate. The output shaft of the adjusting motor 14 is fixedly connected to one end of the combined screw 13, and the other end of the combined screw 13 is connected to the corresponding slide rail 3 through a bearing seat. Connect the adjusting motor to the power supply and turn on the adjusting motor 14. The output shaft of the adjusting motor 14 rotates, which drives the combined screw 13 to rotate. The rotation of the combined screw 13 drives the two movable blocks 12 to move relative to each other or away from each other (the front-to-back distance of the cutting device is half the distance between the two movable blocks 12). This, in turn, drives the two movable plates 6 to rotate, thereby adjusting the angle between the two movable plates 6. The threaded structure between the movable blocks 12 and the combined screw 13 can fix the movable plates 6 and ensure that the hinge between the movable blocks 12 is located in the middle position.

[0034] like Figures 1-3 As shown, in a further preferred embodiment, the regulating motor 14 is a servo motor, which is controlled by a servo controller. Compared with other types of motors, servo motors offer more precise control over speed and position, and are more convenient to use.

The moving blocks 16 are disposed within the moving groove 15 and can slide along it. The moving blocks 16 located on the rear side are limiting structures. The specific structure is as follows: Figure 3 As shown, the rear movable block 16 cannot detach from the corresponding movable groove 15. The front and rear ends of the transmission roller 2 are rotatably connected to the corresponding movable blocks 16. The limiting plate 17 is fixedly installed on the front side of the front movable block 16, and the fastening bolts pass through the limiting plate 17 and are threaded together. Loosening the fastening bolts allows the user to move the movable block 16 by moving the limiting plate, thereby moving the transmission roller 2 and adjusting the gap between the movable rollers 2. Tightening the fastening bolts fixes the limiting plate 17, thereby fixing the position of the transmission roller 2. This moving device has a simple structure and is easy to adjust.

[0036] like Figures 1-3 As shown, in a further preferred embodiment, a movable handle is fixedly installed on the front side of the limiting plate 17. The movable handle 15 provides a point of leverage for the user, facilitating the user to move the limiting plate 17.

[0037] like Figures 1-3 As shown, in a further preferred embodiment, the driving device includes a worm gear 18, several worm wheels 19, and a drive motor 20. The drive motor 20 is fixedly mounted on one side of the mounting bracket 1, specifically on the rear side of the mounting bracket 1. One end of the worm gear 18 is fixedly connected to the output shaft of the drive motor 20. The worm gear 18 is disposed in the rear movable groove 15 and rotatably connected. The worm wheels 19 are respectively fixedly mounted on the mounting shaft of the transmission roller 2. The rear side of the mounting shaft of the transmission roller 2 passes through the corresponding movable block 16 and is rotatably connected.

The rotation of the output shaft of the worm gear 18 can be synchronously rotated through the worm wheels 19, thereby driving the transmission roller 2 to rotate synchronously. This driving device has a simple structure and is easy to use.
