Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flying shear technology, specifically relating to a flying shear with double leveling belts. Background Technology
[0002] Flying shears are a type of shearing machine that performs transverse shearing on moving rolled pieces. They are mainly used to shear medium and small steel billets, thin slabs, small sections (bars), and hot-rolled and cold-rolled strip steel (including coated strips). They are also used to shred the edges of plates cut by disc shears (i.e., edge shredders).
[0003] Currently, flying shears typically perform fixed-length shearing when cutting strip materials. The strip material after fixed-length shearing can be directly processed into corresponding products. However, since the strip material may bend and deform during the conveying process, existing flying shears generally perform the flying shear operation directly on the strip material. This bending and deformation of the strip material will cause deviations in the position of the flying shear cutting the strip material, resulting in strip materials that are too long or too short after cutting. Longer strip materials need to be cut twice before they can be used, while shorter strip materials cannot be used to produce corresponding products, resulting in waste of strip material. Based on this, a flying shear with double flattening strip is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a flying shear machine with a simple structure and reasonable design and double leveling belts in order to solve the above problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A flying shear with dual leveling belts includes a fixed frame and a control panel fixedly connected to the outer surface of the fixed frame. A groove is formed inside the fixed frame, and a first hydraulic cylinder is fixedly connected within the groove. The output end of the first hydraulic cylinder is fixedly connected to a flying shear frame, which is slidably connected to the inner surface of the groove. A second hydraulic cylinder is fixedly connected to the inner top of the flying shear frame, and a cutter is fixedly connected to the output end of the second hydraulic cylinder. A cutting groove adapted to the cutter is formed inside the flying shear frame. A leveling mechanism is fixedly connected to the feed end of the fixed frame, and a conveyor belt is fixedly connected to the discharge end of the fixed frame.
[0007] As a further optimization of this utility model, the top of the conveyor belt is lower than the bottom of the flying shear frame.
[0008] As a further optimization of this utility model, the leveling mechanism includes a fixed seat fixedly connected to the feeding end of the fixed frame. A first motor is fixedly connected to one side of the fixed seat, and a first driving roller is fixedly connected to the output end of the first motor. A first driven roller is rotatably connected inside the fixed seat. The first driving roller and the first driven roller are connected through a lower leveling belt, and the lower leveling belt is in a tensioned state. Two sets of adjusting hydraulic cylinders are fixedly connected to the side wall of the fixed seat. Two fixed plates are fixedly connected to the output ends of the two sets of adjusting hydraulic cylinders. A second motor is fixedly connected to one side of one of the fixed plates, and a second driving roller is fixedly connected to the output end of the second motor. A second driven roller is rotatably connected between the two fixed plates. The second driving roller and the second driven roller are connected through an upper leveling belt, and the upper leveling belt is in a tensioned state. A correction mechanism is fixedly connected to the fixed plate.
[0009] As a further optimization of this utility model, the first active roller is rotatably connected to the fixed base, and the second active roller is rotatably connected to the fixed plate.
[0010] As a further optimization of this utility model, the correction mechanism includes a slide fixedly connected to the end of the fixed plate, a threaded rod rotatably connected inside the slide, an adjusting motor fixedly connected to one side of the fixed plate, the threaded rod being fixedly connected to the output end of the adjusting motor, a sliding plate threaded through the threaded rod, and a limit roller rotatably connected to one side of the sliding plate.
[0011] As a further optimization of this utility model, the threaded rod passes through the fixed plate and is rotatably connected to the fixed plate, and the top of the slide plate is rotatably connected to the inner top of the slide frame.
[0012] The beneficial effects of this utility model are as follows: By using an upper leveling belt, a lower leveling belt, and an adjusting hydraulic cylinder in combination, when shearing strip material, the strip material is first placed between the upper and lower leveling belts. Then, according to the thickness of the strip material, the adjusting hydraulic cylinder is activated to adjust the distance between the upper and lower leveling belts until the upper leveling belt is in contact with the strip material. The strip material can then be conveyed and sheared, thus realizing the leveling operation of the strip material, ensuring the straightness of the strip material, avoiding deviations in the length of the sheared strip material caused by the curling of the strip material, which would render the strip material unusable directly, saving resources, and improving the processing efficiency of subsequent processes.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0019] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a flying shear machine with double leveling belts includes a fixed frame 1 and a control panel 2 fixedly connected to the outer surface of the fixed frame 1. A groove 3 is provided inside the fixed frame 1, and a first hydraulic cylinder 4 is fixedly connected inside the groove 3. The first hydraulic cylinder 4 is controlled by the control panel 2. The output end of the first hydraulic cylinder 4 is fixedly connected to a flying shear frame 5. The flying shear frame 5 is slidably connected to the inner surface of the groove 3. A second hydraulic cylinder 6 is fixedly connected to the inner top of the flying shear frame 5. A cutter 7 is fixedly connected to the output end of the second hydraulic cylinder 6. A cutting groove 8 adapted to the cutter 7 is provided inside the flying shear frame 5. A leveling mechanism is fixedly connected to the feeding end of the fixed frame 1. A conveyor belt 20 is fixedly connected to the discharging end of the fixed frame 1. The top of the conveyor belt 20 is lower than the bottom of the flying shear frame 5. The conveyor belt 20 consists of a base, a motor, a conveyor roller, and a conveyor belt. The first hydraulic cylinder 4, the second hydraulic cylinder 6, and the conveyor belt 20 are controlled by the control panel 2.
[0020] In use, the strip is first placed in the leveling mechanism. Then, the leveling mechanism is activated according to the thickness of the strip so that it can press the strip. At this time, the leveling mechanism can be activated to transport the strip through the flying shear frame 5. When the length of the strip reaches the cutting length, the second hydraulic cylinder 6 is activated to cut the strip with the cutter 7. At the same time, the first hydraulic cylinder 4 is activated to extend so that the flying shear frame 5 moves synchronously and at the same speed as the strip until the cutter 7 cuts the strip and moves upward to detach from the strip. At this time, the first hydraulic cylinder 4 retracts and drives the flying shear frame 5 to reset. The cut strip will fall onto the conveyor belt 20 and be sent to the next process by the conveyor belt 20.
[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the leveling mechanism includes a fixed base 9 fixedly connected to the feed end of the fixed frame 1. A first motor 10 is fixedly connected to one side of the fixed base 9. A first drive roller 11 is fixedly connected to the output end of the first motor 10. The first drive roller 11 is rotatably connected to the fixed base 9. A first driven roller 13 is rotatably connected inside the fixed base 9. The first drive roller 11 and the first driven roller 13 are connected through a lower leveling belt 12, and the lower leveling belt 12 is in a tensioned state. Two sets of adjusting hydraulic cylinders 14 are fixedly connected to the side wall of the fixed base 9. Two fixed plates 15 are fixedly connected to the output ends of the two sets of adjusting hydraulic cylinders 14. A second motor 16 is fixedly connected to one side of a fixed plate 15. A second drive roller 17 is fixedly connected to the output end of the second motor 16. The second drive roller 17 is rotatably connected to the fixed plate 15. A second driven roller 19 is rotatably connected between the two fixed plates 15. The second drive roller 17 and the second driven roller 19 are connected through an upper leveling belt 18, and the upper leveling belt 18 is in a tensioned state. A correction mechanism is fixedly connected to the fixed plate 15. The first motor 10, the second motor 16, and the adjusting hydraulic cylinder 14 are controlled by the control panel 2. The first motor 10 and the second motor 16 are motors of the same model.
[0022] In use, the strip to be cut is first placed between the lower leveling belt 12 and the upper leveling belt 18. Then, the adjusting hydraulic cylinder 14 is activated to make the upper leveling belt 18 fit tightly against the strip. At this time, the first motor 10 and the second motor 16 are started and moved synchronously and at the same speed in opposite directions. The first motor 10 will drive the first drive roller 11 to rotate, which in turn drives the lower leveling belt 12 to move through the first driven roller 13. At the same time, the second motor 16 will drive the second drive roller 17 to rotate, which in turn drives the upper leveling belt 18 to move through the second driven roller 19. This works in conjunction with the lower leveling belt 12 to convey the strip and perform a leveling operation, ensuring the straightness of the strip and avoiding deviations in the length of the cut strip due to the curling of the strip, which would render the strip unusable. This saves resources and improves the processing efficiency of subsequent processes.
[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the correction mechanism includes a slide 25 fixedly connected to the end of the fixed plate 15. A threaded rod 22 is rotatably connected inside the slide 25. The threaded rod 22 passes through the fixed plate 15 and is rotatably connected to the fixed plate 15. An adjusting motor 21 is fixedly connected to one side of the fixed plate 15. The threaded rod 22 is fixedly connected to the output end of the adjusting motor 21. A sliding plate 23 is threadedly connected through the threaded rod 22. The top of the sliding plate 23 is rotatably connected to the inner top of the slide 25. A limit roller 24 is rotatably connected to one side of the sliding plate 23. The adjusting motor 21 is controlled by the control panel 2.
[0024] In use, when the upper leveling belt 18 is in close contact with the strip, the adjusting motor 21 is started to rotate the threaded rod 22. This causes the slide plate 23 to slide along the inner top of the slide 25 under the rotation of the threaded rod 22 and the limiting action of the slide 25, until the outer surface of the limiting roller 24 is in contact with the strip and the edge of the limiting roller 24 is in contact with the edge of the strip. When the strip moves, it will drive the limiting roller 24 to roll. In addition, the edge of the limiting roller 24 will limit the position of the strip to prevent the strip from shifting and becoming non-perpendicular to the cutter 7. This would prevent the cut strip from being directly used for product processing and production, thus ensuring that the strip is always perpendicular to the cutter 7 and that the cut strip can be directly processed into products.
[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
