Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel processing equipment, and in particular to a steel longitudinal shearing device. Background Technology
[0002] In the steel processing industry, slitting is a common process used to cut wide coils or sheets into multiple narrow strips of the required width. Traditional steel slitting equipment typically consists of several basic units, including uncoiling, leveling, slitting, and recoiling.
[0003] In practical applications, existing slitting equipment suffers from several common problems:
[0004] The surface of the steel to be processed may be covered with impurities such as oxide scale, dust or oil. If these impurities are not removed before slitting, they will accelerate the wear of the slitting tool, reduce its service life, and may affect the quality and accuracy of the cut surface due to the inclusion of impurities during the cutting process, and may even lead to the generation of burrs.
[0005] Steel, especially coils, often exhibits bending or wavy deformation after uncoiling. If it is directly slit, the uneven sheet will cause the cutting path to deviate, resulting in uneven cutting width, deviation, and other problems, which seriously affect the precision and quality of the finished product and bring many inconveniences.
[0006] Therefore, this utility model provides a steel longitudinal shearing device. Utility Model Content
[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a steel slitting device that integrates cleaning, leveling, and longitudinal shearing, and has good stability and buffering performance.
[0008] To achieve the above objectives, this utility model adopts the following technical solution: a steel longitudinal shearing device, including a fixing frame,
[0009] The top of the fixed frame is fixedly connected to an anti-falling horizontal plate, and the top of the anti-falling horizontal plate is fixedly connected to two symmetrically distributed limiting plates. A protective baffle is fixedly connected to one side of each of the two limiting plates. A first roller is installed between each of the two protective baffles at equal intervals. A first rotating rod and a second rotating rod are rotatably connected between the two limiting plates. A slitting slitting disc is fixedly connected to the outer side of each of the first rotating rod and the second rotating rod at equal intervals. The first rotating rod is located above the second rotating rod. An auxiliary transmission mechanism that works in conjunction with the first rotating rod and the second rotating rod is installed on one side of one of the limiting plates.
[0010] A second support plate is fixedly connected to one side of the fixed frame. Two symmetrically distributed second support legs are fixedly connected to the bottom of the second support plate. An auxiliary cleaning mechanism is installed on the top of the second support plate. The auxiliary cleaning mechanism includes a second fixed clamping plate. A recycling box and an item storage box are fixedly connected to the top of the second support plate. The recycling box is located on one side of the item storage box. An electric telescopic rod is fixedly connected to the top of the item storage box. A top connecting plate is fixedly connected to the output end of the electric telescopic rod. An installation frame is installed on the top of the top connecting plate. A second fixed clamping plate is fixedly connected to the top of the installation frame. Two second leveling rollers are rotatably connected between the two second fixed clamping plates. The two second leveling rollers are used to perform a surface leveling treatment on the steel to be longitudinally sheared. The steel to be processed is installed above the two second leveling rollers.
[0011] A first support plate is fixedly connected to the other side of the fixed frame. Two symmetrically distributed first support legs are fixedly connected to the bottom of the first support plate. A load-bearing positioning plate is installed on the top of the first support plate, and an auxiliary weighing plate is installed on the top of the load-bearing positioning plate.
[0012] In a preferred embodiment, a fixing rod is fixedly connected to the outer side of each of the two protective baffles. The fixing rod has an L-shaped structure, and a first fixing clamp is fixedly connected to the top of each of the two fixing rods. A cleaning roller is installed between the two first fixing clamps. The recycling box is located on one side of the item storage box and below the cleaning roller. A cleaning brush is installed on the outer side of the cleaning roller. The cleaning roller and the cleaning brush are used to clean the surface of the steel to be longitudinally cut. Equally spaced springs are installed between the top connecting plate and the mounting frame. Each spring has a damper installed inside. The springs and dampers work together to provide buffer protection during longitudinal cutting, thereby extending the service life of the equipment. An adjusting plate is installed between the two protective baffles, and a first leveling roller is installed between the two adjusting plates. The first leveling roller is used to perform secondary leveling on the surface of the steel to be longitudinally cut, thereby improving the accuracy of subsequent operations.
[0013] In a preferred embodiment, the auxiliary transmission mechanism includes a protective cover and a transmission chain. The transmission chain is installed inside the protective cover, and a first pulley and a second pulley are rotatably connected inside the transmission chain. The second pulley is located diagonally above the first pulley and is connected to the first pulley via the transmission chain. A drive motor is fixedly connected inside the fixed frame and to one side of the protective cover. The output end of the drive motor extends into the protective cover and is fixedly connected to one side of the first pulley. A first rotating gear is fixedly connected to one side of the second pulley, and a second rotating gear is rotatably connected above the first rotating gear. Both the first and second rotating gears are located... Inside the protective cover, one end of the first rotating rod is fixedly connected to the second rotating gear, and one end of the second rotating rod is fixedly connected to the first rotating gear. Driven by a motor, the first pulley rotates, which in turn drives the second pulley to rotate via a transmission chain. This, in turn, drives the first rotating gear on one side to rotate. The first rotating gear meshes with the second rotating gear, thereby causing both the first and second rotating rods between the two limiting plates to rotate, performing a longitudinal shearing operation on the steel. A control panel is fixedly connected to one side of the second support plate. The electric telescopic rod and the drive motor are both electrically connected to the control panel. The control panel is used to control the operation of the electric telescopic rod and the drive motor, achieving unified management of the electrical equipment.
[0014] In a preferred embodiment, the bottom of the fixed frame is fixedly connected with first support feet on all four sides, the bottom of each of the two first support legs is fixedly connected with second support feet, and the bottom of each of the two second support legs is fixedly connected with second support feet of the same structure as the bottom of the first support legs. The first and second support legs are provided with auxiliary support by the multiple second support feet, and the fixed frame is supported by the multiple first support feet, thereby improving the stability of the equipment during normal operation.
[0015] In a preferred embodiment, a reinforcing rod is fixedly connected to one side of each of the two second support legs, and one end of each of the two reinforcing rods is fixedly connected to the fixing frame. A reinforcing rod with the same structure as one side of each of the two first support legs is fixedly connected to one side of each of the two first support legs, and one end of each of the two reinforcing rods is fixedly connected to the fixing frame. By using multiple reinforcing rods to reinforce the connection between the second support leg and the fixing frame, and between the first support leg and the fixing frame, the secondary stability of the equipment during normal operation is improved.
[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0017] By setting up a fixed frame, first support leg, second support leg, and control panel, the steel to be slid is first fed onto the surface of two second leveling rollers. The leveling rollers roll on the surface of the steel, and the cleaning brushes on them effectively remove dust, iron filings, and other impurities from the steel surface. The two second leveling rollers are used to perform a surface leveling treatment on the steel to be slid. The removed impurities fall into the recycling box below for centralized processing, maintaining a clean working environment. The output end of the electric telescopic rod can apply controllable pressure to the two second leveling rollers through the top connecting plate and mounting frame. Since the first and second rotating rods are fixedly connected to the second and first rotating gears respectively, the two rotating rods drive the multiple segmented slitting discs fixedly installed on their outer sides to achieve synchronous counter-rotation. The steel passes between high-speed rotating slitting discs and is precisely cut into multiple narrow strips of predetermined width. After slitting, the steel strip continues to move forward and is leveled by the first leveling roller to ensure that the finished product has extremely high flatness. The steel that has completed all processing can be guided to the coiling device or the next process, or it can be placed on the surface of the auxiliary weighing plate. The auxiliary weighing plate can be equipped with pressure sensors for auxiliary weighing, which is convenient for workers to handle later. The stability of the entire device is ensured by the first support leg, the second support leg, and the reinforcing rod connecting the support leg and the fixed frame. Through multiple support and reinforcement structures, the vibration generated during the slitting process is effectively resisted, ensuring processing accuracy and the long-term durability of the equipment.

[0040] Working principle:
[0041] like Figures 1-6 As shown:
[0042] By setting up a fixed frame 1, a first support leg 2, a second support leg 3, and a control panel 18, when in use, the control panel 18 is turned on, and the steel to be longitudinally sheared is first fed onto the surface of two second leveling rollers 45. The cleaning roller 26 rolls on the surface of the steel, and the cleaning brush on it can effectively remove dust, iron filings, and other impurities from the surface of the steel. The two second leveling rollers 45 are used to perform a surface leveling treatment on the steel to be longitudinally sheared. The removed impurities fall into the recycling box 32 below for centralized processing, maintaining a clean working environment. The output end of the electric telescopic rod 41 can be connected to the two second leveling rollers through the top connecting plate 42 and the mounting frame 44. 45 applies controllable pressure, and spring 43 and built-in damper form a buffer, allowing the second leveling roller 45 to adapt to the slight thickness changes of the steel and provide stable clamping force, thereby performing preliminary leveling of the steel, eliminating most of the large bending deformation, and preparing for subsequent high-precision slitting. The steel, after being leveled once, is precisely fed into the slitting area between the two limit plates 13. The drive motor 53 starts, and its output end drives the first pulley 56 to rotate, transmitting power to the second pulley 57 through the transmission chain 55. The second pulley 57 is coaxially fixed with the first rotating gear 58, and the first rotating gear 58 meshes with the second rotating gear 59. This causes the first rotating gear 58 and the second rotating gear 59 to rotate in opposite directions but at synchronized speeds. Since the first rotating rod 5 and the second rotating rod 51 are fixedly connected to the second rotating gear 59 and the first rotating gear 58, respectively, the two rotating rods drive the multiple slitting discs 52 fixedly installed on their outer sides to rotate synchronously in opposite directions. The steel passes between the high-speed, relatively rotating slitting discs and is precisely divided into multiple narrow strips of predetermined width. The steel strips after slitting continue to advance, and the first leveling roller 17 performs a final leveling of the slitting strips to ensure that the finished product has extremely high flatness. Finally, the steel that has completed all processing can be guided... The device can be guided to the winding device or the next process, or it can be placed on the surface of the auxiliary weighing plate 23. The auxiliary weighing plate 23 can be equipped with a pressure sensor for auxiliary weighing, which is convenient for workers to use and retrieve later. Throughout the process, workers can control the drive motor 53 and electric telescopic rod 41 and other electrical equipment through the control panel 18 to achieve convenient automated operation. The stability of the entire device is jointly ensured by the first support foot 11, the second support foot 34 and the reinforcing rod 33 connected between the support leg and the fixed frame. Through multiple support and reinforcement structures, the vibration generated during the slitting process is effectively resisted, ensuring the processing accuracy and long-term durability of the equipment.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
