Description

Technical Field

[0001] This utility model relates to the field of disc shear technology, and more specifically, to an ultra-high strength composite disc shear. Background Technology

[0002] As a key shearing device, the disc shear is widely used in the edge trimming and slitting operations of strip steel and plate. Its main function is to cut wide steel strip coils along the length direction into narrower steel strip coils of a certain size, so as to prepare blanks for subsequent rolling, pipe welding, cold bending and stamping processes. At the same time, by changing the blades of different materials, it can cut various non-ferrous metal strips.

[0003] The upper and lower blades of the existing disc shears are made of rigid materials. When cutting metal strips, this can easily cause poor cutting edges or surface defects. The parts of the metal strip that come into contact with the upper and lower blades are also prone to scratches, especially the lower part of the metal strip that comes into contact with the lower blade, which affects the quality of the metal strip.

[0004] A search revealed that Chinese patent CN207521793U discloses a disc shear. This structure features flexible upper and lower blade sleeves on the blade shaft, with the lower blade sleeve having a larger diameter than the lower blade. During edge cutting, the lower blade sleeve can slightly lift the metal strip, preventing it from contacting the outer edge of the rigid lower blade. This effectively reduces scratches on the metal strip caused by friction with the lower blade, improving the surface quality of the strip. Secondly, both the upper and lower blade sleeves have chamfers, reducing the contact area between the metal strip and the blade sleeves and significantly lowering the coefficient of friction. This ensures the stability of edge plate shape fluctuations during shearing, improving the shearing quality. Furthermore, the upper and lower blade sleeves are made of resin, a flexible material that can buffer shearing force, and the structure is simple and easy to install.

[0005] However, in actual use, in the actual metal strip shearing operation, different strips may have different materials and thicknesses. However, the position of the cutter shaft in this structure has great limitations when adjusting. It may only be able to make simple and limited position changes, and cannot make precise position adjustments according to the specific shearing conditions. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ultra-high strength composite disc shear to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An ultra-high strength composite disc shear includes a frame, a support base on one side of the frame, a fixing frame at the bottom of the frame, and an adjustment mechanism, an upper cutter shaft, and a lower cutter shaft on one side of the frame.

[0009] The adjustment mechanism includes a first motor fixedly installed on the top of the frame. A screw is fixedly installed at the output end of the first motor. A threaded sleeve is connected to the external thread of the screw. One side of the threaded sleeve is connected to the slider. A ball cage connecting shaft is provided on one side of the lower cutter shaft. A main shaft is provided on one side of the upper cutter shaft. A second motor is provided on one side of both the ball cage connecting shaft and the main shaft. The second motor is installed on one side of the support base.

[0010] By adopting the above technical solution, the position of the lower cutter shaft can be precisely adjusted, which can flexibly adapt to different shearing conditions, improve shearing accuracy, and ensure the stability and reliability of power transmission, thus guaranteeing the smooth operation of high-speed shearing.

[0011] As a further description of the above technical solution: the machine frame is provided with a replacement mechanism, the replacement mechanism includes a slide groove opened inside the machine frame, a slider is slidably arranged inside the slide groove, an upper cutter shaft is rotatably arranged inside the machine frame, a lower cutter shaft is rotatably arranged inside the slider, one end of the upper cutter shaft and the lower cutter shaft are threadedly connected to a cutter disc, and the surfaces of the cutter disc, the upper cutter shaft and the lower cutter shaft are all provided with threaded grooves, and bolts are threadedly connected inside the threaded grooves.

[0012] By adopting the above technical solution, the cutter head can be replaced quickly by simply removing the bolts, reducing downtime. The convenient cutter head replacement method and adjustable structure help reduce the difficulty and cost of equipment maintenance and improve overall efficiency.

[0013] As a further description of the above technical solution: a stepper motor is installed on one side of the fixed frame, a lead screw is fixedly installed at the output end of the stepper motor, a movable sleeve is connected to the external thread of the lead screw, the movable sleeve is slidably connected to the fixed frame, the top of the movable sleeve is connected to the frame and the support base, a wear-resistant layer is provided on the surface of the cutter head, the wear-resistant layer is made of titanium nitride, a laser rangefinder and a vision sensor are fixedly installed on one side of the frame, and the laser rangefinder is located on one side of the vision sensor;

[0014] The frame is made of high-quality carbon structural steel. A processor and a controller are installed on one side of the frame, with the processor located on the side of the controller.

[0015] By adopting the above technical solution, the overall position of the machine frame can be flexibly adjusted to adapt to different working scenarios and processing requirements. The titanium nitride wear-resistant layer on the surface of the cutter head enhances the wear resistance of the cutter head, effectively reduces wear, extends the service life of the cutter head, and reduces the replacement frequency and maintenance costs.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up an adjustment mechanism, compared with the existing technology, the stepper motor drives the lead screw, which moves the moving sleeve on the lead screw to achieve fine adjustment of the overall position of the frame. This can adapt to different working scenarios and improve the applicability of the equipment. Moreover, the laser rangefinder and vision sensor monitor the plate parameters in real time, transmit them to the processor and then feed them back to the controller to achieve dynamic adjustment of the shearing process, ensuring shearing accuracy and quality. The second motor drives the ball cage connecting shaft and the main shaft, which drives the cutter head to rotate at high speed. The high-performance power system ensures that the shearing mechanism is stable and reliable when operating at high speed, and improves shearing efficiency.

[0018] 2. By setting up a replacement mechanism, compared with existing technologies, the cutter head is firmly installed on the upper and lower cutter shafts through the cooperation of bolts and threaded grooves. When replacing, only the bolts need to be removed and the cutter head turned down, reducing downtime and facilitating quick maintenance. Moreover, the mechanical simulation of finite element analysis is used to optimize the cutter head design, reduce the risk of fracture caused by local stress concentration, and ensure the reliability of the cutter head during high-speed shearing. Furthermore, the titanium nitride wear-resistant layer on the surface of the cutter head effectively enhances the wear resistance of the cutter head, extends its service life, reduces the cost and time of frequent cutter head replacement, and improves the overall operating efficiency of the equipment.

[0025] 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 protection scope of the present utility model.

[0026] The embodiments disclosed in this application are as follows: Figure 1-5 The ultra-high strength composite disc shear shown includes a frame 1, a support base 2 on one side of the frame 1, a fixing frame 3 at the bottom of the frame 1, and an adjustment mechanism, an upper cutter shaft 6, and a lower cutter shaft 7 on one side of the frame 1.

[0027] The adjustment mechanism includes a first motor 11 fixedly installed on the top of the frame 1. A screw 12 is fixedly installed at the output end of the first motor 11. A threaded sleeve 13 is connected to the external thread of the screw 12. One side of the threaded sleeve 13 is connected to the slider 5. A ball cage connecting shaft 14 is provided on one side of the lower cutter shaft 7. A main shaft 15 is provided on one side of the upper cutter shaft 6. A second motor 16 is provided on one side of both the ball cage connecting shaft 14 and the main shaft 15. The second motor 16 is installed on one side of the support base 2.

[0028] The position of the cutter head is adjusted by means of the adjustment mechanism. The first motor 11 fixed on the top of the frame 1 runs and drives the screw 12 to rotate, so that the threaded sleeve 13 moves on the screw 12. Since one side of the threaded sleeve 13 is connected to the slider 5, the slider 5 will slide in the slide groove 4 inside the frame 1, thereby driving the lower cutter shaft 7 to move, so as to adjust the relative position of the upper and lower cutter heads to adapt to the shearing requirements of different thicknesses.

[0029] The stepper motor 17 on one side of the fixed frame 3 drives the lead screw 18 to rotate. The movable sleeve 19, which is threadedly connected to the lead screw 18, moves on the lead screw 18 and is slidably connected to the fixed frame 3. Because the top of the movable sleeve 19 is connected to the frame 1 and the support base 2, it can achieve fine adjustment of the overall position of the frame 1 to meet the requirements of different working scenarios.

[0030] Reference Figure 2-4 As shown, the machine frame 1 is equipped with a replacement mechanism. The replacement mechanism includes a slide groove 4 opened inside the machine frame 1. A slider 5 is slidably arranged inside the slide groove 4. An upper cutter shaft 6 is rotatably arranged inside the machine frame 1. A lower cutter shaft 7 is rotatably arranged inside the slider 5. A cutter disc 8 is threadedly connected to one end of the upper cutter shaft 6 and the lower cutter shaft 7. Threaded grooves 9 are opened on the surfaces of the cutter disc 8, the upper cutter shaft 6 and the lower cutter shaft 7. Bolts 10 are threadedly connected inside the threaded grooves 9.

[0031] Using the replacement mechanism, the cutter head 8 is installed on the upper cutter shaft 6 and the lower cutter shaft 7 by bolts 10. The threaded grooves 9 on the surfaces of the cutter head 8, the upper cutter shaft 6 and the lower cutter shaft 7 cooperate with the bolts 10 to achieve a firm installation of the cutter head 8. If the cutter head 8 needs to be replaced, simply remove the bolts 10 and rotate the cutter head 8 in the opposite direction.

[0032] The finite element analysis (FEA) is used to perform mechanical simulation on the cutter head 8 to reduce the risk of fracture caused by local stress concentration. At the same time, the wear-resistant layer 20 on the surface of the cutter head 8 is made of titanium nitride, which enhances the wear resistance of the cutter head and extends its service life.

[0033] Reference Figure 4-5 As shown, a stepper motor 17 is installed on one side of the fixed frame 3. A lead screw 18 is fixedly installed at the output end of the stepper motor 17. A movable sleeve 19 is connected to the external thread of the lead screw 18. The movable sleeve 19 is slidably connected to the fixed frame 3. The top of the movable sleeve 19 is connected to the frame 1 and the support base 2. A wear-resistant layer 20 is provided on the surface of the cutter head 8. The wear-resistant layer 20 is made of titanium nitride. A laser rangefinder 21 and a vision sensor 22 are fixedly installed on one side of the frame 1. The laser rangefinder 21 is located on one side of the vision sensor 22.

[0034] The rack 1 is made of high-quality carbon structural steel. A processor 23 and a controller 24 are installed on one side of the rack 1, with the processor 23 located on one side of the controller 24.

[0035] The laser rangefinder 21 and vision sensor 22 on one side of the frame 1 monitor the edge position, thickness and surface defects of the plate in real time. These monitoring data are transmitted to the processor 23, which feeds back these parameters to the controller 24. The controller 24 dynamically adjusts the shearing process based on the feedback parameters.

[0036] The second motor 16, installed on one side of the support base 2, drives the ball cage connecting shaft 14 and the main shaft 15 respectively, which in turn drives the upper cutter shaft 6 and the lower cutter shaft 7 to rotate, causing the cutter head 8 to rotate at high speed to perform shearing work on the strip steel, ensuring its stability and reliability during high-speed operation.

[0037] Working principle of this utility model:

[0038] This utility model is an ultra-high strength composite disc shear. When in use, the device uses a replacement mechanism to install the cutter disc 8 on the upper cutter shaft 6 and the lower cutter shaft 7 by bolts 10. The threaded grooves 9 on the surfaces of the cutter disc 8, the upper cutter shaft 6 and the lower cutter shaft 7 cooperate with the bolts 10 to achieve a firm installation of the cutter disc 8. If the cutter disc 8 needs to be replaced, simply remove the bolts 10 and rotate the cutter disc 8 in the opposite direction.

[0039] In addition, the position of the cutter head is adjusted by means of the adjustment mechanism. The first motor 11 fixed on the top of the frame 1 runs and drives the screw 12 to rotate, so that the threaded sleeve 13 moves on the screw 12. Since one side of the threaded sleeve 13 is connected to the slider 5, the slider 5 will slide in the slide groove 4 inside the frame 1, thereby driving the lower cutter shaft 7 to move, so as to adjust the relative position of the upper and lower cutter heads to adapt to the shearing requirements of different thicknesses.

[0040] The stepper motor 17 on one side of the fixed frame 3 drives the lead screw 18 to rotate. The movable sleeve 19, which is threadedly connected to the lead screw 18, moves on the lead screw 18. The movable sleeve 19 is slidably connected to the fixed frame 3. Because the top of the movable sleeve 19 is connected to the frame 1 and the support base 2, it can achieve fine adjustment of the overall position of the frame 1 to meet the requirements of different working scenarios.

[0041] The finite element analysis (FEA) is used to perform mechanical simulation on the cutter head 8 to reduce the risk of fracture caused by local stress concentration. At the same time, the wear-resistant layer 20 on the surface of the cutter head 8 is made of titanium nitride, which enhances the wear resistance of the cutter head 8 and extends its service life.

[0042] The laser rangefinder 21 and vision sensor 22 on one side of the frame 1 monitor the edge position, thickness and surface defects of the plate in real time. These monitoring data are transmitted to the processor 23, which feeds back these parameters to the controller 24. The controller 24 dynamically adjusts the shearing process based on the feedback parameters.

[0043] The second motor 16, installed on one side of the support base 2, drives the ball cage connecting shaft 14 and the main shaft 15 respectively, which in turn drives the upper cutter shaft 6 and the lower cutter shaft 7 to rotate, causing the cutter head 8 to rotate at high speed to perform shearing work on the strip steel, ensuring its stability and reliability during high-speed operation.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
