Technical Field
[0001] This utility model relates to the field of steel structure bending technology, specifically to a bending device for steel structure processing with adjustable bending angle. Background Technology
[0002] Steel structure engineering is one of the main types of building structures and one of the most common structural forms in modern construction engineering. Steel structure engineering is a structure mainly made of steel. When using steel structures, bending devices are needed to process the steel structure, especially to bend some steel plates.
[0003] Chinese Patent Publication No. CN216226284U discloses a bending device for steel structure processing with adjustable angle, including a base. Side frames are symmetrically fixedly connected to the center of the left and right sides of the base. A top plate is horizontally fixedly connected to the top of the two side frames. An electric push rod is embedded in the center of the top of the top plate. A curved pressure rod is detachably fixedly connected to the bottom of the electric push rod. First fixing grooves are symmetrically formed on the front and back walls of the base. First bidirectional screws are symmetrically rotatably connected to the inner cavities of the two first fixing grooves. A driving mechanism is symmetrically arranged at the front and rear ends of the right side of the base. This bending device for steel structure processing with adjustable angle allows for convenient adjustment of the distance between two placement frames through the interaction of the driving mechanism, the first bidirectional screws, the first fixing grooves, the limiting grooves, and the first moving block. While maintaining a constant support height, changing the support point allows for bending at different angles in conjunction with the electric push rod and the curved pressure rod.
[0004] The aforementioned device places a steel plate between two placement frames and limits its position with a clamping plate. Then, it uses a curved pressure bar to bend the steel plate. However, when the steel plate is bent, both sides will move towards the bending point, which can easily cause the bottom of the steel plate to rub against the placement frame. Moreover, under the action of the clamping plate, the steel plate is prone to wear and scratches. Utility Model Content
[0005] To address the aforementioned issues, a bending device for steel structure processing with adjustable bending angle is provided. By placing a steel plate inside two frames, a screw is rotated to move the mounting frame downwards, and simultaneously, the pressure roller inside the mounting frame also moves downwards, thereby squeezing the steel plate and preventing it from warping up on both sides during the squeezing process. Then, guide rollers inside the frames are used to prevent the steel plate from wearing down due to the downward pressure during bending.
[0006] To address the problems of existing technologies, this utility model provides a bending device for steel structure processing with adjustable bending angle, including a bending seat. Baffles are provided on the top of both sides of the bending seat, and a top seat is provided on the top of each baffle. A bending assembly for bending steel plates is provided at the bottom of the top seat. Movable seats are movably provided on the top of both sides of the bending seat, and a pressing assembly for preventing wear on the steel plates is provided on the top of each movable seat. A connecting rod is rotatably provided on the top of the bending seat, and an adjusting assembly for adjusting the bending angle is rotatably provided outside the connecting rod.
[0007] Preferably, the extrusion assembly includes a frame disposed on top of the movable seat, symmetrical guide rollers rotatably disposed inside the frame, a screw threaded inside the frame, a mounting frame rotatably disposed at the bottom of the screw, a lower pressure roller for extruding the steel plate rotatably disposed inside the mounting frame, and a limiting rod for limiting the position at the top of the mounting frame.
[0008] Preferably, the adjusting assembly includes a first bending plate and a second bending plate rotatably disposed outside the connecting rod, and a connecting block is rotatably disposed at the other end of each of the first bending plate and the second bending plate. A limit block is provided on the side wall of the connecting block, and a limit groove is provided on the side wall of the movable seat for the limit block to move.
[0009] Preferably, the sidewalls of both the first and second bending plates are rotatably equipped with multiple rollers.
[0010] Preferably, the bending assembly includes a pressing rod movably disposed inside the top seat, the top of the pressing rod being provided with an extrusion device, and the bottom of the pressing rod being provided with a bending element for bending the steel plate.
[0011] Preferably, an electric push rod is provided on one side of the baffle, the telescopic end of the electric push rod is connected to the other side wall of the movable seat, a movable wheel is rotatably provided on the top of the movable seat, and a movable groove for the movable wheel to move is provided on the top of the bending seat.
[0012] The advantages of this utility model compared to the prior art are:
[0013] 1. By placing the steel plate inside the two frames, the mounting frame is moved downward by rotating the screw. At the same time, the pressure roller inside the mounting frame also moves downward, thereby squeezing the steel plate and preventing it from warping up on both sides when squeezing the steel plate. Then, the guide roller inside the frame is used to prevent the steel plate from being worn due to the downward pressure when bending.
[0014] 2. The electric push rod drives the two moving seats to move closer or further apart. At the same time, the first bending plate and the second bending plate between the two moving seats will open and close under the action of the limiting block and the limiting groove, thereby adjusting the angle between the first bending plate and the second bending plate, so as to facilitate bending the steel plate into different angles.

[0023] like Figures 1 to 6 As shown, this utility model provides:
[0024] A bending device for steel structure processing with adjustable bending angle includes a bending seat 1, baffles 2 are provided on the top of both sides of the bending seat 1, a top seat 4 is provided on the top of the baffles 2, a bending component for bending the steel plate is provided at the bottom of the top seat 4, movable seats 7 are movably provided on the top of both sides of the bending seat 1, a pressing component for preventing wear on the steel plate is provided on the top of the movable seat 7, a connecting rod 19 is rotatably provided on the top of the bending seat 1, and an adjusting component for adjusting the bending angle is rotatably provided on the outside of the connecting rod 19.
[0025] The bending angle of the steel plate can be adjusted by adjusting the components, thereby improving the convenience of bending. Then, the steel plate is bent by the bending components.
[0026] like Figure 4 As shown, the extrusion assembly includes a frame 6 disposed on top of the movable seat 7. Symmetrical guide rollers 11 are rotatably disposed inside the frame 6. A screw 14 is threaded inside the frame 6. A mounting frame 12 is rotatably disposed at the bottom of the screw 14. A lower pressure roller 10 for extruding the steel plate is rotatably disposed inside the mounting frame 12. A limiting rod 13 for limiting the position is disposed at the top of the mounting frame 12.
[0027] By placing the steel plate inside the two frames 6, and then rotating the screw 14 to drive the mounting frame 12 to move downward, the lower pressure roller 10 inside the mounting frame 12 will also move downward, thereby squeezing the steel plate and preventing it from warping up on both sides when squeezing the steel plate. Then, the guide roller inside the frame 6 is used to ensure that the steel plate will not be worn due to the downward pressure when bending.
[0028] like Figure 3 and Figure 5 As shown, the adjustment assembly includes a first bending plate 8 and a second bending plate 16 rotatably disposed outside the connecting rod 19. A connecting block 17 is rotatably disposed at the other end of both the first bending plate 8 and the second bending plate 16. A limit block 18 is provided on the side wall of the connecting block 17, and a limit groove for the limit block 18 to move is provided on the side wall of the movable seat 7.
[0029] The first bending plate 8 and the second bending plate 16 between the two movable seats 7 will open and close under the action of the limiting block 18 and the limiting groove, thereby adjusting the angle between the first bending plate 8 and the second bending plate 16, so as to facilitate bending the steel plate into different angles.
[0030] like Figure 5 As shown, multiple rollers 15 are rotatably mounted on the side walls of both the first bending plate 8 and the second bending plate 16.
[0031] The use of roller 15 can further reduce the wear of steel plates during bending.
[0032] like Figure 1As shown, the bending assembly includes a pressing rod 5 movably disposed inside the top seat 4. A pressing device is provided at the top of the pressing rod 5, and a bending member 20 for bending the steel plate is provided at the bottom of the pressing rod 5.
[0033] The extrusion equipment drives the lower pressure rod 5 to work, which in turn drives the bending component 20 at the bottom of the lower pressure rod 5 to bend the steel plate.
[0034] like Figure 1 As shown, an electric push rod 3 is provided on one side of the baffle 2. The telescopic end of the electric push rod 3 is connected to the other side wall of the movable seat 7. A movable wheel 9 is rotatably provided on the top of the movable seat 7. A movable groove for the movable wheel 9 to move is provided on the top of the bending seat 1.
[0035] The electric push rod 3 first moves the two movable seats 7 closer or further apart, thus facilitating the adjustment of the bending angle of the steel plate. At the same time, the movable wheels 9 make the movable seats 7 move more smoothly.
[0036] Working principle: When the steel plate needs to be bent, the electric push rod 3 first drives the two moving seats 7 to move closer or further apart. At the same time, the first bending plate 8 and the second bending plate 16 between the two moving seats 7 will open and close under the action of the limiting block 18 and the limiting groove, thereby adjusting the angle between the first bending plate 8 and the second bending plate 16, so as to bend the steel plate into different angles. After adjusting to the appropriate angle, the steel plate is placed inside the two frames 6. Then, the screw 14 is rotated to drive the mounting frame 12 to move downward. At the same time, the lower pressure roller 10 inside the mounting frame 12 will also move downward, thereby squeezing the steel plate and preventing the two sides from curling up when squeezing the steel plate. Then, the guide roller inside the frame 6 is used to prevent the steel plate from being worn due to the downward pressure during bending.
[0037] The above embodiments merely illustrate one or several implementation methods of the bending device for steel structure processing with adjustable bending angle according to this utility model.
