Description

Technical Field

[0001] This application relates to the field of angle steel production line technology, and in particular to a shearing device for an angle steel production line. Background Technology

[0002] Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouse shelves, etc.

[0003] Patent document CN222078110U discloses a shearing device for an angle steel production line, including a base plate, vertical plates, a square groove, an angle steel placement platform, angle steel, a pressing assembly, and a shearing assembly. The vertical plates are positioned above the base plate, and the angle steel placement platform is positioned on the upper surface of the base plate. The angle steel is placed on the angle steel placement platform, which is positioned between two vertical plates. This invention uses a cylinder pressing plate assembly to compress and fix the angle steel, and then uses the shearing assembly to shear the angle steel. During the shearing process, the angle steel will not shake under the shearing force, avoiding uneven shearing end faces and not affecting the shearing quality of the angle steel. Furthermore, the flat cross-section of the angle steel will not cause scratches on the shearing blade after shearing, thus improving the service life of the blade.

[0004] Patent document CN205519164U discloses a positionable angle steel shearing device, including a worktable. A lower module is provided on the upper surface of the worktable, with the feed end as the rear. A support plate is provided on one side of the rear end face of the lower module, and a baffle is fixedly connected to one side of the front end face of the lower module. An upper module is attached to the upper rear end face of the lower module and is mounted on the punch of a shearing machine. This invention allows for manual positioning of the required length of angle steel to be cut, and the device also provides a certain degree of safety protection, preventing operators from putting their hands into the cutting area.

[0005] However, the aforementioned patent documents are not convenient for automatic collection of the sheared angle steel during use, requiring manual handling, which leads to the sharp edges of the sheared angle steel being easily scratched, posing a significant risk. Therefore, we propose an angle steel production line shearing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing shearing devices, which are inconvenient for automatically collecting sheared angle steel during use, requiring manual handling, and thus causing the sharp edges of the sheared angle steel to be easily scratched, posing a significant risk. Therefore, this invention proposes a shearing device for an angle steel production line.

[0007] The shearing device for an angle steel production line provided in this application adopts the following technical solution:

[0008] A shearing device for an angle steel production line includes a processing table, a support frame, and a collection box. The support frame is fixedly installed on the top of the processing table, and the collection box is installed on one side of the processing table. It also includes:

[0009] The hydraulic cylinder is fixedly mounted on the top of the bracket, and the output shaft of the hydraulic cylinder is fixedly connected to the shearing blade.

[0010] The movable plate is slidably installed inside the bracket. The movable plate is equipped with a positioning mechanism for fixing and positioning the angle steel.

[0011] A through groove is provided on the support, and an installation groove is provided inside the processing table.

[0012] Furthermore, the positioning mechanism includes a V-shaped pressure plate, which is fixedly installed at the bottom of the movable plate. A support column is fixedly installed on the top of the processing table. The V-shaped pressure plate cooperates with the support column. Through the cooperation between the V-shaped pressure plate and the support column, the angle steel can be stably positioned.

[0013] Furthermore, a first sprocket and a second sprocket are fixedly mounted on the outer sides of the two screws respectively. The first sprocket and the second sprocket are meshed with the same first chain. When the screws rotate, the first sprocket and the second sprocket are driven by the first chain.

[0014] Furthermore, a third sprocket is fixedly installed at the other end of the rotating shaft, and a fourth sprocket is fixedly installed at one end of the rotating rod. The third sprocket and the fourth sprocket are meshed with the same second chain. When the rotating shaft rotates, the third sprocket drives the fourth sprocket to rotate through the second chain.

[0015] Furthermore, a second through hole is provided on one side of the inner wall of the mounting groove. A rotating shaft is rotatably installed in the second through hole. A second bevel gear and a first bevel gear are fixedly installed at one end of the rotating shaft and one end of the screw, respectively. The second bevel gear and the first bevel gear mesh with each other. When the screw rotates, the first bevel gear drives the second bevel gear to rotate.

[0016] Furthermore, the top of the bracket has two symmetrical first through holes, and a screw is rotatably installed in each of the two first through holes. Both screws are threadedly connected to the movable plate. A motor is fixedly installed on the top of the bracket, and the output shaft of the motor is fixedly connected to one end of the screw. When the motor is turned on, the screw drives the movable plate to move vertically.

[0017] Furthermore, the processing table has an installation port, in which two rotating rods are rotatably installed. Conveyor rollers are fixedly installed on the outer side of each of the two rotating rods, and the same conveyor belt is driven to the two conveyor rollers.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This solution, by setting up a conveyor and collection mechanism consisting of a conveyor belt and a collection box on the processing table, can automatically transport the angle steel to the designated collection position after it is cut, completely avoiding the manual handling of the cut angle steel, fundamentally eliminating the safety risk of operators being scratched by the sharp edges of the angle steel, and improving production safety.

[0020] 2. This solution links the positioning mechanism used to fix the angle steel with the conveyor belt used to transport the angle steel through a transmission system. Only one motor needs to be driven to complete the clamping and positioning of the angle steel while providing power for subsequent automatic conveying. This simplifies the device structure, reduces manufacturing costs, and ensures the coordination and reliability of the actions.

[0021] This invention automates the entire process of positioning, cutting, and collecting angle steel by simultaneously pressing and shearing the angle steel and then automatically transporting the sheared angle steel segments to a collection box. This completely eliminates the risk of scratches caused by manual handling of the sheared parts and simplifies the device structure. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1:

[0029] Reference Figures 1-4 A shearing device for an angle steel production line includes a processing table 1, a support 2, and a collection box 3. The support 2 is fixedly installed on the top of the processing table 1, and the collection box 3 is installed on one side of the processing table 1. It also includes:

[0030] Hydraulic cylinder 5 is fixedly installed on the top of bracket 2, and the output shaft of hydraulic cylinder 5 is fixedly connected to shearing blade 6;

[0031] Movable plate 11 is slidably installed in bracket 2. Movable plate 11 is provided with positioning mechanism, which is used to fix and position angle steel.

[0032] Through groove 7 is provided on bracket 2, and mounting groove is provided inside processing table 1.

[0033] In this embodiment, a first sprocket 14 and a second sprocket 16 are fixedly installed on the outer sides of the two screws 17, respectively. The first sprocket 14 and the second sprocket 16 are meshed with the same first chain 15. When the screw 17 rotates, the first sprocket 14 and the second sprocket 16 are driven by the first chain 15. A second through hole is opened on one side of the inner wall of the mounting groove. A rotating shaft 20 is rotatably installed in the second through hole. A second bevel gear 19 and a first bevel gear 18 are fixedly installed at one end of the rotating shaft 20 and one end of the screw 17, respectively. The second bevel gear 19 and the first bevel gear 18 mesh with each other. When the screw 17 rotates, the first bevel gear 18 drives the second bevel gear 19 to rotate. An installation port 4 is opened on the processing table 1. Two rotating rods 8 are rotatably installed in the installation port 4. A conveyor roller is fixedly installed on the outer side of each of the two rotating rods 8. The same conveyor belt 9 is connected to the two conveyor rollers.

[0034] In this embodiment, the positioning mechanism includes a V-shaped pressure plate 12, which is fixedly installed at the bottom of the movable plate 11. A support column 13 is fixedly installed on the top of the processing table 1. The V-shaped pressure plate 12 and the support column 13 cooperate with each other. Through the cooperation of the V-shaped pressure plate 12 and the support column 13, the angle steel can be stably positioned. A third sprocket 21 is fixedly installed at the other end of the rotating shaft 20, and a fourth sprocket 23 is fixedly installed at one end of the rotating rod 8. The third sprocket 21 and the fourth sprocket 23 are meshed with the same second chain 22. When the rotating shaft 20 rotates, the third sprocket 21 drives the fourth sprocket 23 to rotate through the second chain 22. The top of the bracket 2 has two symmetrical first through holes. A screw 17 is rotatably installed in each of the two first through holes. Both screws 17 are threadedly connected to the movable plate 11. A motor 10 is fixedly installed on the top of the bracket 2. The output shaft of the motor 10 is fixedly connected to one end of the screw 17. When the motor 10 is turned on, the screw 17 drives the movable plate 11 to move vertically.

[0035] The implementation principle of the shearing device for an angle steel production line according to this application embodiment is as follows: First, the angle steel to be sheared is placed on the support column 13 of the processing table 1. The motor 10 is started, and the output shaft of the motor 10 drives the screw 17 connected to it to rotate. The screw 17 drives the other screw 17 to rotate synchronously through the transmission of the first chain 15, the first sprocket 14, and the second sprocket 16. The two screws 17 simultaneously drive the movable plate 11 threadedly connected to it to move downward along the bracket 2. The V-shaped pressure plate 12 fixed at the bottom of the movable plate 11 descends accordingly and cooperates with the support column 13 below to firmly press and fix the angle steel. At this time, the hydraulic cylinder 5 is started to push the shearing cutter 6 downward, thereby completing the precise shearing of the angle steel. During this process, because the angle steel is stably pressed, the shaking during shearing is effectively avoided, ensuring the quality of the cross-section. During the process, the first bevel gear 18 at one end also rotates and meshes with the second bevel gear 19 to rotate, thereby driving the rotating shaft 20 to rotate. The third sprocket 21 at the other end of the rotating shaft 20 transmits power to the fourth sprocket 23 through the second chain 22, thereby driving the rotating rod 8 and the conveyor roller and conveyor belt 9 mounted on it to operate. This means that while the angle steel is being pressed and fixed, the conveyor belt 9 is already in a drive standby state. After the shearing is completed, the hydraulic cylinder 5 drives the shearing cutter 6 to reset. Then, the control motor 10 reverses and drives the movable plate 11 together with the V-shaped pressure plate 12 to rise, releasing the sheared angle steel segment. At this time, the continuously running conveyor belt 9 immediately transports the angle steel segment that falls on its surface horizontally out of the processing table 1, and finally slides into or falls into the collection box 3 on the side, completing the automatic collection. The whole process is continuous and automatic, without the need for manual intervention.

[0036] Example 2:

[0037] The difference between this embodiment and embodiment one is that two symmetrical guide shafts are slidably installed on the movable plate 11. The two ends of the guide shafts are fixedly connected to the top inner wall of the bracket 2 and the top of the processing table 1, respectively. When the movable plate 11 moves vertically, the two guide shafts can stabilize the vertical movement of the movable plate 11.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
