Description

Technical Field

[0001] The invention belongs to the technical field of hot-rolled steel plate processing, and in particular relates to a hot-rolled steel plate cutting device. Background Art

[0002] Hot rolled steel plate is a steel product that changes its shape, size and performance by heating the steel to above its recrystallization temperature and then passing it 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 rougher and their dimensional tolerances are larger, but they have better formability and lower production costs. Hot rolled steel plates are widely used in industries such as construction, bridges, shipbuilding, automobile manufacturing, and mechanical processing, and are mainly used to make structural steel, thin plates, thick plates and other products. Due to its good plasticity, strength and adaptability, hot rolled steel plates occupy an important position in the global steel market.

[0003] During the rolling process of hot-rolled steel plates, due to uneven heating and stress on the steel, slight ripples, unevenness or bending often appear on the surface. During the operation of existing hot-rolled steel plate cutting devices, due to the uneven state of the steel plate surface, a large number of burrs will appear during the cutting process, and the cutting blade will be damaged, thereby reducing the quality of the steel plate. In addition, the current hot-rolled steel plate cutting devices can usually only cut steel plates of a single size, width and height during operation, resulting in great limitations in the processing of steel plates. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a hot-rolled steel plate cutting device.

[0005] The technical solution adopted to solve the above technical problems is: a hot-rolled steel plate cutting device, comprising a main body, a base is fixedly connected to the bottom of the main body, and a transmission mechanism is installed inside the main body;

[0006] A cutting box is fixedly connected to the top of the middle end of the main body, a plurality of distance control mechanisms are installed on the top of the inner wall of the cutting box, an adjustment mechanism is installed on one side of the plurality of distance control mechanisms, and a cutting mechanism is installed on the bottom of the inner wall of the cutting box.

[0007] The cutting box is provided with grooves inside for sliding of a plurality of adjusting mechanisms.

[0008] Furthermore, the transmission mechanism includes a first motor fixedly connected to the rear end of the main body, a plurality of transmission rollers are rotatably connected inside the main body, a movement groove is opened on the rear end plate of the main body, the outer walls of the rear ends of the plurality of transmission rollers are fixedly connected to synchronous wheels, the outer walls of the plurality of synchronous wheels are meshed with synchronous toothed belts, and the rear end of one of the transmission rollers is fixedly connected to the output end of the first motor.

[0009] Through the above technical scheme, when in use, when the hot-rolled steel plate that has undergone multiple processes needs to be cut, it can be transported by a transmission mechanism to the cutting processing position, and can provide power to move to one side to ensure that the cutting of the hot-rolled steel plate can be completed smoothly. Specifically, when the hot-rolled steel plate is transmitted to the cutting device after processing, the first motor at the rear end of the main body can be started to drive one of the transmission rollers to rotate, and then the multiple transmission rollers can be rotated under the connection of the synchronous toothed belts meshing on multiple synchronous wheels, so that the hot-rolled steel plate on the device can keep moving and provide a force to move to one side.

[0010] Furthermore, the distance control mechanism includes a second motor fixedly connected to the top of the rear end of the cutting box, the output end of the second motor is fixedly connected to a screw rod, a plurality of sliding grooves are opened inside the cutting box, the screw rod is located inside the cutting box, and the screw rods are respectively located in the corresponding sliding grooves.

[0011] Through the above technical scheme, when the hot-rolled steel plate is transported to the processing position, it can be selected according to the specifications of the steel plate. At the same time, the distance control mechanism is used to ensure the required width of the steel plate when cutting. This working process can control the distance of the tool so that the steel plate can be achieved in various sizes. The independent control of the blade is helpful to optimize the cutting path during cutting and reduce waste generation. Specifically, by starting the second motor at the top of the rear end of multiple cutting boxes to drive the screw to rotate, it can then drive the tool to move on the sliding groove. On this basis, each group of second motors can drive two tools to move, the outermost tool is a group, and the innermost tool is a group, which are matched in sequence, so that the outermost tool can be matched with several other tools, and the second outermost layer can be matched with the rest, so as to achieve various sizes.

[0012] Furthermore, the adjusting mechanism includes a fixed box slidably connected to the inner wall of the corresponding sliding groove, the fixed box is provided with a movable groove inside, the top of the fixed box is fixedly connected to a hydraulic cylinder, the inner wall of the movable groove is slidably connected to a third motor, the output end of the third motor is fixedly connected to a driving shaft, the bottom of the fixed box is fixedly connected to a fixed frame, sleeve rods are sleeved on both sides of the fixed frame, a slicing support shell is rotatably connected between the two sleeve rods, a connecting rod is fixedly connected to the bottom of the outer wall of the driving shaft, the other end of the connecting rod is threadedly connected to a threaded rod, the top of the slicing support shell is fixedly connected to a sliding column, the inside of one side of the fixed box is threadedly connected to the corresponding screw rod, the top of the third motor is fixedly connected to the piston rod of the hydraulic cylinder, the inner wall of the fixed frame ring is rotatably connected to the driving shaft, the outer wall of the sliding column is slidably connected to the bottom ring of the threaded rod, and the outer wall of the threaded rod is provided with a threaded groove.

[0013] Through the above technical scheme, after the steel plate enters, it can be selected in conjunction with the distance control mechanism, and the adjustment mechanism is used to cooperate with it, so that after the width size is selected, the thickness of the steel plate can be selected, and it can be moved down according to the steel plate cutting process to ensure sufficient cutting. In addition, when the steel plate undergoes hot rolling operation and cooling process, when the surface of the steel plate changes, the cutting angle of the tool can be adjusted according to the deformation of the steel plate surface such as concave and convex to ensure that the tool is perpendicular to the cut surface during cutting, and then the flatness of the cut surface can be ensured, the flatness of the cut surface can be ensured, and burrs can be reduced, which can avoid excessive wear of the tool, improve the cutting quality, reduce the roughness difference of the steel plate surface, and effectively deal with the surface irregularity problem of hot-rolled steel plates caused by the rolling process. Specifically, When the steel plate enters, the movement of the screw rod will drive the fixed box to move along the sliding groove. When the width size adjustment is completed, the hydraulic cylinder can be started to push downward to make the third motor move downward along the movable groove. At the same time, the drive shaft will move downward, so that the two sleeve rods will break away from the fixed frame and extend downward, thereby driving the slicing support shell to move downward. When the tool is close to the steel plate, it stops. When the surface of the steel plate is deformed, the third motor can be started to drive the connecting rod on the driving shaft to rotate. At this time, the connecting rod will move in a circle, thereby driving the threaded rod to move, so that the threaded rod slides on the sliding column, thereby realizing the offset of the slicing support shell. When the connecting rod rotates, it will move on the threaded rod. At the same time, the limit on the threaded rod and the connecting rod is to avoid obstacles in the process of the tool moving up and down.

[0014] Furthermore, the cutting mechanism includes a fourth motor fixedly connected to the bottom of the rear end of the cutting box, the output end of the fourth motor is fixedly connected to the first position-limiting telescopic rod, the other end of the first position-limiting telescopic rod is fixedly connected to a universal shaft, the other end of the universal shaft is fixedly connected to a second position-limiting telescopic rod, the inside of the slicing support shell is rotatably connected with a cutter, the front end of the universal shaft is rotatably connected to the outer wall of the slicing support shell, and the connecting rod between the first position-limiting telescopic rod and the second position-limiting telescopic rod is fixed with a cutter.

[0015] Through the above technical scheme, when the steel plate reaches the processing position and is adjusted by the distance control mechanism and the adjustment mechanism, the cutting mechanism can be used to cut it. During the process of width adjustment and thickness adjustment, the position of the tool will change. At this time, normal cutting can be performed after adjustment through the cutting mechanism. The rotation of multiple blades can be controlled by a single motor, which can achieve an efficient cutting process, reduce the complexity of mechanical transmission, save energy, and improve work efficiency. In addition, during the cutting process, the adjusting mechanism can be coordinated to move with the degree of cutting thickness of the steel plate, so that the hot-rolled steel plate can be fully cut when cutting, and when the tool descends while rotating, the cutting surface of the steel plate can also be adjusted. It can rotate quickly to achieve the effect of cutting and grinding at the same time. At the same time, in cooperation with the distance control mechanism, multiple tools can be cut at the same time, so that when cutting the hot-rolled steel plate, the steel plate can be guaranteed to be more stable on the transmission mechanism. At the same time, when cutting multiple sizes, the cutting line can be kept in a straight line. Specifically, after the adjustment is completed, the fourth motor at the bottom of the rear end of the cutting box can be started to drive the first limiting telescopic rod to rotate, and then under the connection of the first limiting telescopic rod, multiple second limiting telescopic rods and multiple universal shafts, multiple cutters are rotated to cut the hot-rolled steel plate. Under the limitation of the first limiting telescopic rod, the second limiting telescopic rod and the special structure, not only the width and thickness can be adjusted, but also normal rotation can be guaranteed.

[0016] The beneficial effects of the present invention are as follows: (1) By designing a transmission mechanism, a distance control mechanism, an adjustment mechanism and a cutting mechanism, the present invention can select according to the size of the steel plate when the hot-rolled steel plate cutting device is working, and can select multiple sizes at the same time, and can select the cutting angle according to the unevenness caused by the hot and cold changes of the steel plate processing, thereby ensuring the cutting quality of the steel plate; (2) By designing a transmission mechanism and a distance control mechanism, the hot-rolled steel plate is cut as the transmission mechanism moves after processing, and the cutting of the steel plate by the tool is controlled by multiple screws, so that the tool can be adjusted independently, and different blades can cut different widths or different The invention can improve the working efficiency by adjusting the cutting angle of the blade to reduce the burr generation and improve the cutting quality. In addition, the invention can ensure the stability of the steel plate when the steel plate is embedded in the cutting process by multiple cutting tools, effectively avoiding the occurrence of sliding and tilting of the cutting surface. (3) The invention can control the height of the blade according to the design of the adjusting mechanism and the cutting mechanism, so as to adapt to the cutting height of different hot-rolled steel plates. Meanwhile, the hot-rolled steel plates will be affected by the temperature change during the processing. By controlling the cutting angle of the blade, the direction and distribution of the cutting force can be adjusted, the burr generation can be reduced, and the cutting quality can be improved.

Specifically, when the hot-rolled steel plate is transmitted to the cutting device after processing, the first motor 301 at the rear end of the main body 1 can be started to drive one of the transmission rollers 302 to rotate, and then the multiple transmission rollers 302 can be rotated under the connection of the synchronous toothed belt 305 meshing on the multiple synchronous wheels 304, so that the hot-rolled steel plate on the device can keep moving and provide a force to move to one side.

[0029] like Figure 6 As shown, a cutting box 4 is fixedly connected to the top of the middle end of the main body 1, and a plurality of distance control mechanisms 5 are installed on the top of the inner wall of the cutting box 4. The distance control mechanism 5 includes a second motor 501 fixedly connected to the top of the rear end of the cutting box 4, and a screw rod 502 is fixedly connected to the output end of the second motor 501. A plurality of sliding grooves 503 are opened inside the cutting box 4, and the screw rod 502 is located inside the cutting box 4. The screw rod 502 is respectively located in the corresponding sliding grooves 503. When the hot-rolled steel plate is transported to the position to be processed, it can be selected according to the specifications of the steel plate. At the same time, the distance control mechanism 5 is used to ensure the required width when the steel plate is cut. This working process can control the knife The distance between the tools can make the steel plate achieve a variety of sizes. The independent control of the blade helps to optimize the cutting path during cutting and reduce waste generation. Specifically, by starting the second motor 501 at the top of the rear end of the multiple cutting boxes 4 to drive the screw rod 502 to rotate, and then drive the tool to move on the sliding groove 503. On this basis, each group of second motors 501 can drive two tools to move, the outermost tools are one group, and the innermost tools are one group, which are matched in sequence, so that the outermost tools can be matched with other tools, and the second outermost layer can be matched with the rest, so as to achieve a variety of sizes.

[0030] like Figure 6-Figure 9As shown, one side of the multiple distance control mechanisms 5 is installed with an adjusting mechanism 6, the adjusting mechanism 6 includes a fixed box 601 slidably connected to the inner wall of the corresponding sliding groove 503, a movable groove 602 is opened inside the fixed box 601, a hydraulic cylinder 603 is fixedly connected to the top of the fixed box 601, a third motor 604 is slidably connected to the inner wall of the movable groove 602, a driving shaft 605 is fixedly connected to the output end of the third motor 604, a fixed frame 606 is fixedly connected to the bottom of the fixed box 601, sleeve rods 607 are sleeved on both sides of the fixed frame 606, a slicing support shell 608 is rotatably connected between the two sleeve rods 607, a connecting rod 609 is fixedly connected to the bottom of the outer wall of the driving shaft 605, and a threaded rod 610 is threadedly connected to the other end of the connecting rod 609. The top of the sheet support shell 608 is fixedly connected with a slide column 611, and the inside of one side of the fixed box 601 is threadedly connected to the corresponding screw rod 502. The top of the third motor 604 is fixedly connected to the piston rod of the hydraulic cylinder 603, and the inner wall of the ring of the fixed frame 606 is rotatably connected to the drive shaft 605. The outer wall of the slide column 611 is slidably connected to the bottom ring of the threaded rod 610. The outer wall of the threaded rod 610 is provided with a threaded groove. When the steel plate enters, it can be selected in conjunction with the distance control mechanism 5. At this time, the adjustment mechanism 6 is used to cooperate with it, so that after the width size is selected, the steel plate thickness can be selected, and at the same time, it can be moved down according to the steel plate cutting process to ensure sufficient cutting. In addition, when the steel plate undergoes hot rolling operation and cooling process, when the surface of the steel plate changes At this time, the cutting angle of the tool can be adjusted according to the deformation of the steel plate surface, such as bumps, to ensure that the tool can be perpendicular to the cut surface during cutting, thereby ensuring the flatness of the cut surface, reducing burrs, avoiding excessive wear of the tool, and improving the cutting quality, reducing the roughness difference of the steel plate surface, and effectively dealing with the surface irregularity problem of the hot-rolled steel plate caused by the rolling process. Specifically, after the steel plate enters, with the movement of the screw rod 502, the fixed box 601 will be driven to move along the sliding groove 503. When the width size adjustment is completed, the hydraulic cylinder 603 can be started to push downward so that the third motor 604 moves downward along the movable groove 602. At the same time , the driving shaft 605 will move downward, so that the two sleeve rods 607 will break away from the fixed frame 606 and extend downward, thereby driving the slicing support shell 608 to move downward. When the tool is close to the steel plate, it stops. When the surface of the steel plate is deformed, the third motor 604 can be started to drive the connecting rod 609 on the driving shaft 605 to rotate. At this time, the connecting rod 609 will perform a circular motion, thereby driving the threaded rod 610 to move, so that the threaded rod 610 slides on the sliding column 611, thereby realizing the offset of the slicing support shell 608. When the connecting rod 609 rotates, it will move on the threaded rod 610. At the same time, the limit of the threaded rod 610 and the connecting rod 609 is to avoid obstacles in the process of the tool moving up and down.

[0031] like Figure 6-Figure 8As shown, a cutting mechanism 7 is installed at the bottom of the inner wall of the cutting box 4, and a groove is opened inside the cutting box 4 for sliding of multiple adjustment mechanisms 6. The cutting mechanism 7 includes a fourth motor 701 fixedly connected to the bottom of the rear end of the cutting box 4, and the output end of the fourth motor 701 is fixedly connected to a first limit telescopic rod 702, and the other end of the first limit telescopic rod 702 is fixedly connected to a universal shaft 703, and the other end of the universal shaft 703 is fixedly connected to a second limit telescopic rod 704. A cutter 705 is rotatably connected inside the slicing support shell 608, and the front end of the universal shaft 703 is connected to the outer surface of the slicing support shell 608. The wall is rotatably connected, and a cutter 705 is fixed on the connecting rod between the first limiting telescopic rod 702 and the second limiting telescopic rod 704. When the steel plate reaches the processing position and is adjusted by the distance control mechanism 5 and the adjustment mechanism 6, the cutting mechanism 7 can be used to cut it. During the process of adjusting the width and thickness, the position of the tool will change. At this time, the cutting mechanism 7 can be adjusted accordingly to perform normal cutting, and the rotation of multiple blades can be controlled by a single motor, so that an efficient cutting process can be achieved, the complexity of mechanical transmission is reduced, energy is saved, and work efficiency is improved. In addition, during the cutting process, the adjusting mechanism 6 can be coordinated to move with the degree of cutting thickness of the steel plate, so that the hot-rolled steel plate can be fully cut when cutting. When the tool descends, the cutting surface of the steel plate can also be quickly rotated in the case of rotation, so as to achieve the effect of cutting and grinding at the same time. At the same time, in cooperation with the distance control mechanism 5, multiple tools can be cut at the same time, and then when cutting the hot-rolled steel plate, it can ensure that the steel plate is more stable on the transmission mechanism 3. At the same time, when cutting multiple sizes, It can keep the cutting line in a straight line state. Specifically, when the adjustment is completed, the fourth motor 701 at the bottom of the rear end of the cutting box 4 can be started to drive the first limiting telescopic rod 702 to rotate, and then under the connection of the first limiting telescopic rod 702, multiple second limiting telescopic rods 704 and multiple universal shafts 703, multiple cutters 705 are rotated to cut the hot-rolled steel plate. Under the limitation of the first limiting telescopic rod 702 and the second limiting telescopic rod 704 and the special structure, not only the width and thickness can be adjusted, but also normal rotation can be guaranteed.

[0032] The working principle of this embodiment is as follows. When in use, after the hot-rolled steel plate is processed and transmitted to the cutting device, the first motor 301 at the rear end of the main body 1 can be started to drive one of the transmission rollers 302 to rotate, and then the multiple transmission rollers 302 can be rotated under the connection of the synchronous toothed belts 305 meshing on the multiple synchronous wheels 304. When the hot-rolled steel plate is transported to the processing position, the second motor 501 at the top of the rear end of the multiple cutting boxes 4 is started to drive the screw rod 502 to rotate, and then the tool can be driven to move on the sliding groove 503. With the movement of the screw rod 502, the fixed box 601 will be driven to move along the sliding groove 503. When the width size adjustment is completed, the hydraulic cylinder 603 can be started to push downward so that the third motor 604 moves downward along the movable groove 602. At the same time, the drive shaft 605 will move forward accordingly. The downward movement causes the two sleeve rods 607 to separate from the fixed frame 606 and extend downward, thereby driving the slicing support shell 608 to move downward. When the tool is close to the steel plate, it stops. After the adjustment is completed, the fourth motor 701 at the bottom of the rear end of the cutting box 4 can be started to drive the first limit telescopic rod 702 to rotate, and then under the connection of the first limit telescopic rod 702, multiple second limit telescopic rods 704 and multiple universal shafts 703, multiple cutters 705 are rotated. When the surface of the steel plate is deformed, the third motor 604 can be started to drive the connecting rod 609 on the drive shaft 605 to rotate. At this time, the connecting rod 609 will perform a circular motion, thereby driving the threaded rod 610 to move, so that the threaded rod 610 slides on the sliding column 611, thereby realizing the offset of the slicing support shell 608, and then continuing to cut until the hot-rolled steel plate cutting work is completed.
