For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0026] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] like Figure 1-8 As shown, an embodiment of the present invention provides a steel structure bending device, including a bending die, a base 1, a feeding mechanism 3, an intermediate seat 4, a movable plate 11 and a support plate 14. The device can realize multi-point bending of steel structure parts in one operation, and also realizes automatic loading and unloading of steel structure parts, greatly improving production efficiency.

[0028] The middle seat 4 is fixed to the middle of the upper end surface of the base 1, and a workbench 12 is arranged on the top of the middle seat 4. The back plate 8 is arranged on one side of the middle seat 4, and the top plate 7 is fixed on the top side of the back plate 8 to form a stable frame structure. The upper end surface of the top plate 7 is fixed with a cylinder 9, and its output end is connected to the movable plate 11 located between the top plate 7 and the workbench 12. Guide cylinders 17 are installed at the four corners of the lower end surface of the top plate 7, and guide rods 19 passing through the guide cylinders 17 are installed at the four corners of the upper end surface of the movable plate 11. A fixed seat 6 is installed on the lower end surface of the movable plate 11, and a pressure head 16 is installed on the fixed seat 6. A punching hole 21 is arranged on the workbench 12, and a bending mold is installed on the lower end surface of the workbench 12 and directly facing the punching hole 21.

[0029] As the core component of the bending device, the bending die is directly involved in the shaping process of the steel structure. It consists of a base plate 22, a die frame 23 and a bending column 25. The die frame 23 is embedded in the punching hole 21 and fixed on the upper end surface of the base plate 22, and the base plate 22 is fixed to the lower end surface of the workbench 12 through the connecting columns 24 distributed at its four corners. A rotating groove for installing the bending column 25 is provided on the die frame 23, so that it can rotate around the rotating groove or adjust the angle. The bending column 25 is embedded in the rotating groove of the die frame 23, and a V-shaped notch 28 is provided on the cylindrical surface of the bending column 25. A through hole 26 connected to the rotating groove is provided on one side of the die frame 23, and a threaded hole 27 connected to the through hole 26 is provided on the table surface of the die frame 23. A dial plate 32 is inserted on the cylindrical surface of the bending column 25, and a long strip hole 31 is provided at one end of the dial plate 32. The threaded hole 27 is screwed into the threaded column 29, and the lower end of the threaded column 29 passes through the long hole 31. The threaded column 29 is covered with a spring 30, which is pressed between the dial plate 32 and the inner top wall of the through hole 26.

[0030] During the bending process, the steel structure is placed at a designated position on the workbench 12. The oil cylinder 9 is started, the piston rod inside it extends, and the movable plate 11 then moves in the vertical direction, gradually approaching the workbench 12 below. When the movable plate 11 moves downward to the predetermined position, the pressure head 16 will accurately press against the bending column 25, and accurately embed the part of the steel structure that needs to be bent into the V-shaped recess 28 on the bending column 25. As the pressure head 16 continues to press downward, the bending column 25 is deflected by the thrust from the pressure head 16, and the pressure is transmitted to the bending part of the steel structure through the side wall of the recess 28, guiding and pushing the bending part to gradually rise according to the predetermined angle and curvature. During the deflection of the bending column 25, the dial plate 32 on it rotates accordingly, the spring 30 is compressed, and the potential energy increases. When the pressure head 16 is pressed down to a predetermined position and maintained for a period of time to ensure that the bending part is fully deformed, the cylinder 9 retracts, the movable plate 11 rises accordingly, the pressure head 16 separates from the bending column 25, and the spring 30 recovers. The thrust generated resets the bending column 25, completing a precise end face bending operation.

[0031] The lower end surface of the movable plate 11 is hinged with side pressure plates 20 on both sides, and the upper end surface of the movable plate 11 is installed with support frames 18 on both sides. Each support frame 18 is hinged with a cylinder 10, and the output end of the cylinder 10 is hinged to the side pressure plate 20 on the same side. When the movable plate 11 moves downward, the side pressure plate 20 will also approach the workbench 12, and provide an initial downward force when it contacts the steel structure. During the bending process, the cylinder 10 pushes the side pressure plate 20 to rotate, and the initial downward force is converted into a lateral clamping force, thereby realizing the lateral bending of the steel structure.

[0032] Pressing mechanisms 5 are respectively provided on both sides of the lower end surface of the movable plate 11 to help stably press the steel structure on the workbench 12 to prevent it from moving during the bending process. Each pressing mechanism 5 is located at the hinge between the side pressure plate 20 and the movable plate 11.

[0033] The pressing mechanism 5 includes a pressing seat 37 and a seat body 33 fixed to the lower end surface of the movable plate 11. The lower end surface of the seat body 33 is provided with a guide hole 34, and one side of the seat body 33 is provided with an oblong hole 39 connected to the guide hole 34. The upper end surface of the pressing seat 37 is provided with a guide column 35 embedded in the guide hole 34, and one side of the top of the guide column 35 is provided with a stopper 36 passing through the oblong hole 39. The guide column 35 is covered with a spring 2 38, and the spring 2 38 is pressed between the pressing seat 37 and the seat body 33.

[0034] When the movable plate 11 moves downward, the pressure seat 37 first contacts the steel structure and applies a certain downward force. As the movable plate 11 continues to descend, the pressure seat 37 will be subjected to the reaction force from the steel structure and move upward, at which time the second spring 38 is compressed and stores energy. When the movable plate 11 stops descending and starts to bend, the second spring 38 will use its stored elastic potential energy to help the pressure seat 37 maintain a stable clamping of the steel structure to prevent it from moving or deflecting during the bending process.

[0035] The middle seat 4 is provided with an upper support plate 13 and a lower support plate 15 spaced apart from each other below the workbench 12, and the support plate 14 is located between the upper support plate 13 and the lower support plate 15. The upper support plate 13 is provided with a second cylinder 43, and a positioning block 42 is provided at the output end of the second cylinder 43. The positioning block 42 is adapted to the position of the reserved hole on the steel structure, and the workbench 12 is provided with a positioning hole facing the positioning block 42. The second cylinder 43 pushes the positioning block 42 out of the reserved hole of the steel structure to limit the position of the steel structure.

[0036] A cylinder 40 is installed on the lower support plate 15, and the output end of the cylinder 40 is connected to the bottom of the pallet 14. Roller conveyor belts 41 are installed on both sides of the upper end surface of the pallet 14. Guide sleeves 45 are arranged on both sides of the upper end surface of the lower support plate 15, and guide rods 44 passing through the guide sleeves 45 are arranged on both sides of the lower end surface of the pallet 14. When the steel structure completes the lateral bending, the cylinder 40 pushes the pallet 14 upward, the roller conveyor belt 41 lifts the steel structure, and then the roller conveyor belt 41 starts to send the steel structure out of the bending equipment.

[0037] An intermediate seat 4 is fixedly installed in the middle of the upper end surface of the base 1, and linear modules 2 are installed on both sides of the upper end surface of the base 1 (the linear module is a linear transmission device widely used in the industrial field. The working principle of the linear module is to convert the rotational motion of the servo motor or handwheel into linear motion, thereby driving the slider to slide on the linear guide rail to achieve high-precision repetitive linear motion), and a feeding mechanism 3 is installed at the output end of the linear module 2, and the two groups of feeding mechanisms 3 are arranged opposite to each other.

[0038] The feeding mechanism 3 includes a stand 46 installed at the output end of the linear module 2. A cylinder 3 49 is installed on the side of the stand 46 facing the middle seat 4. The output end of the cylinder 3 49 is connected to a movable seat 48. The movable seat 48 is slidably connected to the stand 46. A mounting plate 47 is provided on one side of the movable seat 48. A roller conveyor belt 2 is installed on the table of the mounting plate 47. The spacing between the two sets of feeding mechanisms 3 can be adjusted by the linear module 2, which can adapt to the initial length of the steel structure and also provide a preliminary positioning for the steel structure. The two ends of the steel structure are placed on the roller conveyor belt 2. When started, the roller conveyor belt 2 will feed the steel structure to be bent into the bending device.

[0039] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention.
