Description

Technical Field

[0001] The present invention relates to the technical field of steel structure processing, in particular to a bending device for steel structure processing which is easy to adjust and operate. Background Art

[0002] In recent years, with the rapid development of industries such as construction, bridges, and machinery manufacturing, steel structures such as steel plates have been widely used in various types of engineering construction due to their advantages such as high strength, light weight, and short construction period. In the processing of steel structures, bending is one of the key processes, which directly affects the quality of steel structure components and the overall performance of the project. Traditional bending methods for steel plate processing generally have many limitations. On the one hand, the equipment operation and adjustment are complicated. When replacing bending molds of different sizes, some devices require a lot of tedious manual disassembly, installation, and debugging work. This not only consumes time and manpower costs, but also requires a high level of technical skills from the operators, resulting in low processing efficiency. On the other hand, the versatility of existing devices is poor, and they can often only bend steel plates of specific specifications, making it difficult to meet diverse production needs. When it is necessary to process steel plates of different sizes, equipment often needs to be replaced, which undoubtedly increases the company's equipment procurement costs and production management difficulties. Announcement No. CN208960685U discloses a plate bending device, which relates to the field of steel structure processing technology, including a base plate, a bending mold and a driving device; the bending mold includes a mold base, a bending die, a bending punch and two pads; the mold base is connected to the base plate, the bending die is connected to the mold base, and the bending die has a mold cavity; the two pads are respectively located on both sides of the mold cavity mouth, and the pads are provided with guide arcs; the bending punch is placed on the mold base and is located directly in front of the mold cavity; the driving device includes a driving device base and a jack, the driving device base is connected to the base plate, the jack is connected to the driving device base, the piston rod of the jack is connected to the bending punch, and the jack can drive the bending punch into or away from the mold cavity. Although the above device simplifies the mechanism and facilitates rapid bending work, a single bending mold can only perform bending of a single size. When encountering large quantities and requiring bending operations of different sizes, replacing the mold will take a lot of time and needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to solve the technical problems raised in the above background technology.

[0004] The present invention adopts the following technical solution: a bending device for steel structure processing that is easy to adjust and operate, comprising a base, a fixed plate fixedly connected to the side of the base, a transmission mechanism fixedly connected to the surface of the fixed plate, a screw rotatably connected to the interior of the base, a mold frame threadedly connected to the surface of the screw, a bottom plate fixedly connected to the interior of the base, a fixed block A fixedly connected to the surface of the base, a hydraulic cylinder A fixedly connected to the surface of the fixed block A, a connecting block fixedly connected to the output end of the hydraulic cylinder A, a slider A slidingly connected to the interior of the connecting block, a punch fixedly connected to the surface of the slider A, a slider B slidingly connected to the interior of the mold frame, a die fixedly connected to the surface of the slider B, and a cylinder fixedly connected to the interior of the base.

[0005] Preferably, the transmission mechanism includes a motor A, the output end of which is fixedly connected to a gear A, and the base is internally rotatably connected to a gear B. Here, motor A is a variable frequency speed motor, which can flexibly adjust the speed according to processing requirements.

[0007] Preferably, the surface of the mold frame is slidably connected to the interior of the base, and the die is composed of multiple rectangular blocks of the same main body size but with internal grooves of varying sizes. The well-designed sliding connection between the mold frame and the base ensures the stability and accuracy of the mold frame during movement. The diverse design and quick-change connection of the die allows operators to quickly replace the appropriate die according to the bending requirements of steel plates of varying specifications and shapes, eliminating the need for complex adjustment and installation procedures. This significantly improves the device's adaptability to diverse steel structure processing tasks, reduces processing preparation time, and improves overall processing efficiency.

[0009] Preferably, two hydraulic cylinders B are symmetrically located on either side of hydraulic cylinder A. The lower ends of the rotating drums A and B are rotatably connected to the push block and the interior of the die, respectively. The columns A and rotating drums A are each provided within the die. The two symmetrically located hydraulic cylinders B, combined with the rotating drums A and B, further optimize the stress state during the steel plate bending process, ensuring balanced force on the steel plate during bending and improving the stability and reliability of the bending process.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

The present invention is provided with a transmission mechanism, a mold frame, a slider A, a die, a cylinder, etc., wherein the output of the motor A is used to mesh with the gear A and the gear B to further drive the screw to rotate to select dies of different sizes, and then push the screw onto the cylinder to advance the working area. The bending molds of different sizes can be quickly selected according to the curvature of the steel plate to be bent, thereby improving the processing efficiency. At the same time, the punch and the connecting block are slidably connected by the slider A, so that the punch can be quickly replaced to adapt to the use of the corresponding die. The quick replacement structure can effectively reduce the time spent on changing the mold and improve the processing efficiency.

[0012] 2. In the present invention, a hydraulic cylinder B, a push block, a vertical pole A, a vertical pole B, a rotating drum A and a rotating drum B are arranged. The hydraulic cylinder B pushes the push block to clamp and fix steel plates of different sizes, thereby reducing the risk of instability of the steel plates and their separation from the working area during bending.

Here, the fixed plate 2 is made of high-strength alloy material and is firmly connected to the side of the base 1 through a welding process, providing a stable installation foundation for subsequent components. The two ends of the screw 4 are connected to the inside of the base 1 through high-precision bearings to reduce rotational friction. The bottom plate 6 is made of thickened steel plate to enhance the overall structural strength of the base 1. The hydraulic cylinder A8 and the fixed block A7 are connected by a flange for easy disassembly and maintenance. The inner wall of the connecting block 9 is provided with a slide groove, and the slider A10 slides in the slide groove to facilitate the replacement of the punch 11. The mold frame 5 is provided with a guide groove, and the slider B12 slides in the guide groove to ensure the linearity of the sliding. The transmission mechanism 3 includes a motor A31, and the output end of the motor A31 is fixedly connected to the gear A32, and the internal rotation of the base 1 is connected to the gear B33. Here, motor A31 is a variable frequency speed motor that can flexibly adjust its speed according to processing requirements. Gear A32 uses a high-precision involute gear that meshes with gear B33 to ensure smooth and accurate transmission. The surface of screw 4 is fixedly connected to the interior of gear B33, and the interior of base 1 is rotationally connected to the surface of gear A32. Here, the surface of screw 4 and the interior of gear B33 are fixed via a key connection to ensure the reliability of power transmission and prevent relative rotation.

[0027] Example 2

[0028] See also Figure 1 、 Figure 6-8 The surface of the bottom plate 6 is fixedly connected to a fixed block B15, the surface of the fixed block B15 is fixedly connected to a hydraulic cylinder B16, the output end of the hydraulic cylinder B16 is fixedly connected to a push block 17, the interior of the push block 17 is fixedly connected to a column A18, the surface of the column A18 is rotatably connected to a rotating drum A19, the interior of the die 13 is fixedly connected to a column B20, and the surface of the column B20 is rotatably connected to a rotating drum B21. Here, the hydraulic cylinder B16 can push the push block 17 to clamp and fix steel plates of different sizes. The column A18, rotating drum A19, column B20 and rotating drum B21 play the same role in fixing the workpiece while reducing damage to the workpiece surface during bending. There are two hydraulic cylinders B16 and they are symmetrically distributed on both sides of the hydraulic cylinder A8. The lower ends of the rotating drums A19 and B21 are rotatably connected to the push block 17 and the interior of the die 13 respectively. The column A18 and rotating drum A19 are set in each die 13. Here, the two symmetrically distributed hydraulic cylinders B16 cooperate with the setting of rotating drums A19 and B21 to further optimize the stress state during the bending process of the steel structure, ensure the force balance of the steel plate when bending, and improve the stability and reliability of the bending process.

[0029] Working principle: First, after the motor A31 is started, the gear A32 at its output end rotates accordingly. The gear A32 and the gear B33 engage with each other to transmit power stably to the gear B33. Then the rotation of the gear B33 drives the screw 4 to rotate synchronously. The screw 4 drives the die 13 to move. Different sizes of dies 13 can be selected. After the appropriate die 13 is selected, the cylinder 14 is activated to push the die 13 upward to the working area. At the same time, the steel plate is placed upright between the push block 17 and the die 13, and then the hydraulic cylinder B16 is started to push the push block 17 to tighten the steel plate. After the processed steel plate is fixed, the corresponding punch 11 is selected according to the selected die 13 and installed on the connecting block 9 through the slider A10. The hydraulic cylinder A8 is started to push the punch 11 to perform the bending work. The steel plate will move during the bending process. At this time, the rotating drum A19 and the rotating drum B21 on the surface of the column A18 and the column B20 rotate to allow the steel plate to move while effectively reducing the damage to the surface of the steel plate during the movement. The push block 17 is pushed by the hydraulic cylinder B16 to fix the steel plate, which can make the processing process more stable and reduce the risk of the steel plate leaving the working area due to force.
