Description

Technical Field

[0001] This application relates to the field of strip steel production, and in particular to a strip steel shearing device that is easy to position. Background Technology

[0002] In traditional strip shearing processes, several common technical methods are typically employed to transport and shear the strip. On one hand, ordinary conveying devices are used to move the strip; these devices are generally simple roller or conveyor belt structures, with a motor driving the rollers to rotate, thus moving the strip. On the other hand, for the shearing operation, ordinary shearing blades are mostly used, utilizing hydraulic systems or mechanical transmissions to provide shearing force and cut the strip.

[0003] However, the strip may shift during the shearing process. To position the strip, a positioning mechanism is usually installed. The positioning mechanism typically includes two positioning rods that can move towards or away from each other. By adjusting the two positioning rods to move towards each other, the strip is clamped in the middle of the strip shearing device, thus completing the positioning of the strip.

[0004] However, during the clamping process of the two positioning rods, the strip may be clamped on both sides and bulge upwards, resulting in a lower quality of the finished strip. Summary of the Invention

[0005] To ensure the quality of the sheared strip steel finished product, this application provides a strip steel shearing device that is easy to position.

[0006] The strip shearing device for easy positioning provided in this application adopts the following technical solution: A strip steel shearing device for easy positioning includes a shearing mechanism, a discharge conveying mechanism located on one side of the shearing mechanism, and a positioning mechanism. The discharge conveying mechanism includes multiple conveying rollers. The positioning mechanism includes a pair of positioning rods and a control component that drives the pair of positioning rods to move closer to or further apart. The pair of positioning rods are located between two adjacent conveying rollers. Each positioning rod is slidably connected to a pressing rod for pressing against the upper surface of the strip steel. Each positioning rod is equipped with a conveying mechanism that drives the pressing rod to rise and fall.

[0007] By adopting the above technical solution, the strip steel shearing device has a discharge conveying mechanism and a positioning mechanism. The strip steel passes through the shearing mechanism and is conveyed to the discharge conveying mechanism, whose conveying rollers can transport the strip steel. Subsequently, the positioning mechanism is activated, and the positioning rods move closer together and clamp the strip steel under the drive of the control components. Then, the conveying mechanism drives the pressure rod to descend and press against the upper surface of the strip steel, thereby positioning and pressing the strip steel, reducing the occurrence of strip steel bulging, facilitating the positioning and shearing of the strip steel by the strip steel shearing device, and ensuring the quality of the sheared strip steel finished product.

[0008] Preferably, each of the pair of positioning rods has an installation groove on one side that is close to each other, and a positioning block is slidably connected in each installation groove. A transmission groove is also provided on one side that is close to each other, and a communication port is provided on the lower side wall of each transmission groove, communicating with the corresponding installation groove. The transmission mechanism includes a rack rod 1 and a rack rod 2 slidably connected in the installation groove. The lower end of rack rod 1 passes through the communication port and extends into the installation groove. The bottom surface of rack rod 1 is an inclined surface that contacts the positioning block. A connecting rod is fixedly connected between rack rod 2 and the pressing rod. A transmission gear is rotatably connected in the installation groove. The transmission gear is located between rack rod 1 and rack rod 2, and both rack rod 1 and rack rod 2 mesh with the gear.

[0009] By adopting the above technical solution, during the process of the positioning rod clamping the strip steel, the strip steel pushes the positioning block to slide within the mounting groove. Since the bottom surface of rack one is an inclined surface that contacts the positioning block, the movement of the positioning block pushes rack one upward within the mounting groove through this inclined surface. Furthermore, because the transmission gear, which is rotatably connected within the mounting groove, is located between rack one and rack two, and both rack one and rack two mesh with the transmission gear, the upward movement of rack one will drive the transmission gear to rotate, thereby causing rack two, which meshes with the transmission gear, to descend. Rack two and the pressure rod are fixedly connected by a connecting rod. The descent of rack two will drive the connecting rod and the pressure rod to descend, ultimately causing the pressure rod to contact the strip steel, achieving pressure on the upper surface of the strip steel and enhancing the positioning effect.

[0010] Preferably, a transmission spring is fixedly connected between the upper side wall of the mounting groove and the rack rod.

[0011] By adopting the above technical solution, the transmission spring can provide elastic support for the rack rod, enabling the rack rod to return to its original position under the action of the transmission spring after displacement, ensuring stable operation of the transmission mechanism and improving the reliability of strip positioning and shearing.

[0012] Preferably, a guide rod is fixedly connected to the upper end of the rack rod, and a guide groove is provided on the upper side wall of the mounting groove, with the guide rod inserted into the guide groove.

[0013] By adopting the above technical solution, the insertion and cooperation between the guide rod and the guide groove can provide guidance for the rack rod when the transmission spring extends and retracts, so that the rack rod can perform lifting and lowering movements more stably.

[0014] Preferably, a return spring is installed between the bottom wall of the mounting groove and the positioning block. One end of the return spring is fixedly connected to the bottom wall of the mounting groove, and the other end is fixedly connected to a mounting rod for abutting the positioning block. An adjustment mechanism is connected to the mounting rod to drive the mounting rod to move closer to or further away from the positioning block.

[0015] By adopting the above technical solution, when two positioning blocks are needed to clamp the strip, the adjusting mechanism drives the mounting rod to move away from the positioning blocks, thereby compressing the return spring. This allows the positioning blocks to be pushed by the strip without having to overcome the force of the return spring, facilitating the smooth pushing of the positioning blocks and the conveying mechanism by the strip, and thus allowing the pressure rod to press down smoothly. When it is not necessary to position the strip, the pair of positioning rods are controlled to move away from each other, and the adjusting mechanism drives the mounting rod to move closer to the positioning blocks, thereby pushing the positioning blocks to reset.

[0016] Preferably, the adjusting mechanism includes an elliptical block rotatably connected to the side wall of the positioning rod away from the positioning block. Both ends of the mounting rod are fixedly connected to transition rods. The two transition rods penetrate the bottom wall of the mounting groove, and a receiving rod is fixedly connected between the ends of the two transition rods away from the mounting rod. When one end of the major axis of the elliptical block abuts against the receiving rod, the return spring is compressed, and the mounting rod disengages from the contact positioning block. A driving component for driving the elliptical block to rotate is installed on the positioning rod.

[0017] By adopting the above technical solution, when one end of the elliptical block's major axis abuts against the receiving rod, the return spring is compressed, causing the mounting rod to disengage from the contact positioning block. This allows the strip steel to apply force to the positioning block, aligning the positioning blocks. When adjusting the positioning block to reset, the elliptical block can be driven to rotate via the driving component. At this time, the major axis of the elliptical block gradually disengages from the receiving rod, while the mounting rod, under the force of the return spring, moves towards the positioning block and pushes it to reset. The operation is simple and convenient.

[0018] Preferably, the positioning rod has two fixed blocks fixedly connected to one side away from the positioning block, and a rotating shaft is rotatably connected between the two fixed blocks. The rotating shaft is fixedly coaxially with the elliptical block. The driving component includes a gear one fixedly coaxially with the rotating shaft, and a gear two meshing with the gear one and rotatably connected to one of the fixed blocks. A drive motor is fixedly connected to the positioning rod, and the output shaft of the drive motor is fixedly coaxially with the gear two.

[0019] By adopting the above technical solution, when one end of the elliptical block in the major axis direction detaches from the receiving block, the drive motor can be turned off. At this time, the mounting rod moves rapidly towards the positioning block under the force of the return spring, and the receiving rod also moves rapidly towards the positioning rod under the force of the return spring, thereby pushing the elliptical block to rotate. This makes the resetting process of the positioning block relatively rapid.

[0020] Preferably, the diameter of the second gear is smaller than the diameter of the first gear.

[0021] By adopting the above technical solution, under the condition that the drive motor outputs the same power, the gear can rotate at a lower speed, thereby allowing the elliptical block to rotate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: To achieve the positioning and clamping of the strip steel, reduce the occurrence of strip steel bulging, facilitate the positioning and shearing of the strip steel by the strip steel shearing device, and ensure the quality of the sheared strip steel finished product; This achieves pressure on the upper surface of the strip steel, enhancing the positioning effect of the strip steel; The resetting process of the positioning block is relatively quick.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a strip shearing device that facilitates positioning. (Refer to...) Figure 1 and Figure 2 The strip shearing device includes a shearing mechanism 1, a discharge conveying mechanism 2 located on one side of the shearing mechanism 1, and a positioning mechanism 3 for positioning the strip. The strip passes through the shearing mechanism 1 and moves onto the discharge conveying mechanism 2. Then, the strip is positioned by the positioning mechanism 3, and finally, the strip is sheared by the shearing mechanism 1. After shearing, the strip is transported to the next working area along the discharge conveying mechanism 2.

[0030] The discharge conveying mechanism 2 includes a support frame 21 and multiple conveying rollers 22 rotatably connected to the support frame 21. The conveying rollers 22 are typically made of metal with a smooth surface to reduce friction with the strip steel and ensure smooth movement. Each pair of adjacent conveying rollers 22 is connected at one end by a sprocket and chain. A conveying motor 23 is fixedly connected to the support frame 21, and the output shaft of the conveying motor 23 is coaxially fixed with one of the conveying rollers 22. The multiple conveying rollers 22 are arranged in parallel, and the conveying motor 23 drives the multiple conveying rollers 22 to rotate, thereby realizing the conveying of the strip steel.

[0031] Reference Figure 2 and Figure 3 The positioning mechanism 3 includes a pair of positioning rods 31 and a control component 32 that drives the pair of positioning rods 31 to move closer to or away from each other. A slider 33 is fixedly connected to the bottom end of each positioning rod 31. A groove 211 is provided on the support frame 21, and each slider 33 is slidably connected to the groove 211. The control component 32 can be a hydraulic cylinder 321 or an electric push rod, etc. In this embodiment, the control component 32 is a hydraulic cylinder 321. The two positioning rods 31 are located between the two hydraulic cylinders 321, with one hydraulic cylinder 321 corresponding to one positioning rod 31. The piston rod of the hydraulic cylinder 321 is fixedly connected to the positioning rod 31.

[0032] Simultaneously, two hydraulic cylinders 321 are activated, and a pair of positioning rods 31 can be adjusted according to the width of the strip to achieve positioning of strips of different specifications.

[0033] A pair of positioning rods 31 are located between two adjacent conveying rollers 22, and each positioning rod 31 is vertically slidably connected to a pressing rod 34 for pressing against the upper surface of the strip. Each positioning rod 31 is equipped with a conveying mechanism 4 that drives the pressing rod 34 to rise and fall.

[0034] Reference Figure 2 and Figure 3 Each pair of positioning rods 31 has a mounting groove 311 on one side that is close to each other, and a positioning block 35 is slidably connected in each mounting groove 311. The sides of the two positioning blocks 35 that are close to each other are arc-shaped, which restricts the strip from moving up and down along the positioning block 35 when the positioning block 35 is in contact with the side of the strip.

[0035] A transmission groove 312 is also provided on one side of a pair of positioning rods 31 that are close to each other. The lower side wall of each transmission groove 312 is provided with a communication port 313 that communicates with the corresponding mounting groove 311. The transmission mechanism 4 includes a rack rod 41 and a rack rod 42 that are vertically slidably connected in the mounting groove 311.

[0036] The lower end of rack rod 41 passes through the connecting port 313 and extends into the mounting groove 311. The bottom surface of rack rod 41 is an inclined surface that gradually slopes upwards towards the positioning block 35, and the inclined surface is used to abut against the positioning block 35. A transmission gear 43 is rotatably connected in the mounting groove 311. The transmission gear 43 is located between rack rod 41 and rack rod 42, and the sides of rack rod 41 and rack rod 42 that are close to each other are engaged with the transmission gear 43. Each rack rod 42 is fixedly connected to the corresponding pressing rod 34 by a connecting rod 44. A transmission spring 45 is provided in the mounting groove 311. One end of the transmission spring 45 is fixedly connected to the upper side wall of the mounting groove 311, and the other end is fixedly connected to the upper end of rack rod 41.

[0037] Reference Figure 2 and Figure 3 The two positioning rods 31 move closer to each other until both positioning blocks 35 contact the strip. At this point, the two positioning rods 31 continue to move towards each other. The positioning blocks 35 slide within the mounting groove 311 and contact the inclined surface of the rack rod 41, thereby pushing the rack rod 41 upward and compressing the transmission spring 45. At this time, through gear transmission, the rack rod 42, connecting rod 44, and pressing rod 34 slide in opposite directions, thereby lowering the pressing rod 34. The pressing rod 34 contacts the strip, restricting the strip from tilting upward or moving during the shearing process.

[0038] A guide rod 46 is fixedly connected to the upper end of the rack rod 41, and a guide groove 314 is provided on the upper side wall of the mounting groove 311. The guide rod 46 is slidably inserted into the guide groove 314.

[0039] Reference Figure 3 and Figure 4 A return spring 5 is installed between the bottom wall of the mounting groove 311 and the positioning block 35. One end of the return spring 5 is fixedly connected to the bottom wall of the mounting groove 311, and the other end is fixedly connected to a mounting rod 6 for abutting against the positioning block 35. Both ends of the mounting rod 6 are fixedly connected to transition rods 61. Both transition rods 61 penetrate the bottom wall of the mounting groove 311 and extend out of the mounting groove 311. A receiving rod 62 is fixedly connected between the ends of the two transition rods 61 extending out of the mounting groove 311. An adjustment mechanism 7 is connected to the mounting rod 6 to drive the mounting rod 6 to move closer to or further away from the positioning block 35.

[0040] The adjustment mechanism 7 includes two fixed blocks 71 fixedly connected to the side wall of the positioning rod 31 opposite to the positioning block 35, and an elliptical block 72 rotatably connected between the two fixed blocks 71. A driving component 73 for driving the elliptical block 72 to rotate is mounted on the positioning rod 31.

[0041] Reference Figure 3 and Figure 4The driving component 73 includes a first gear 731 fixed coaxially with the rotating shaft, and a second gear 732 rotatably connected to a fixing block 71. The first gear 731 and the second gear 732 mesh with each other. A drive motor 733 is fixedly connected to the side of the positioning rod 31 opposite to the positioning block 35. The output shaft of the drive motor 733 is fixed coaxially with the second gear 732. The diameter of the second gear 732 is smaller than the diameter of the first gear 731.

[0042] When one end of the major axis of the elliptical block 72 abuts against the receiving rod 62, the return spring 5 is compressed, and the mounting rod 6 disengages from the contact positioning block 35. At this time, when the positioning block 35 contacts the strip, the strip can smoothly push the positioning block 35 to move. When the positioning block 35 disengages from the strip and needs to be adjusted to reset, the drive motor 733 drives the gear 2 732 to rotate, and then through the meshing transmission of gear 1 731 and gear 2 732, the elliptical block 72 rotates. The major axis of the elliptical block 72 gradually disengages from the receiving rod 62. At this time, the drive motor 733 is turned off, and under the force of the return spring 5, the receiving rod 62, the two transition rods 61, and the mounting rod 6 can move towards the positioning block 35. The mounting rod 6 pushes the positioning block 35 to quickly reset.

[0043] The implementation principle of a strip steel shearing device for easy positioning according to an embodiment of this application is as follows: When using this strip steel shearing device, the control component 32 first drives a pair of positioning rods 31 to move closer to each other, adapting them to the width of the strip steel. When the two positioning blocks 35 contact the strip steel, the two positioning rods 31 continue to move closer to each other. The positioning blocks 35 push the pressing rod 34 down through the conveying mechanism 4 to contact the strip steel. At this point, the two positioning rods 31 stop moving, and the positioning is completed. Subsequently, the strip steel is sheared by the shearing mechanism 1.

[0044] After shearing, the control unit 32 drives a pair of positioning rods 31 to move away from each other. The drive motor 733 drives gear 732 to rotate, which in turn causes the elliptical block 72 to rotate via gear 731. At this time, the return spring 5 pushes the mounting rod 6 to move closer to the positioning block 35, and pushes the positioning block 35 to reset. The sheared strip can then be conveyed to the next working area along the discharge conveyor mechanism 2.

[0045] 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.
