Description

Technical Field

[0001] This utility model relates to the field of C-shaped steel processing technology, and in particular to a bending device for adjusting the curvature of C-shaped steel. Background Technology

[0002] C-shaped steel is a type of steel with a C-shaped cross-section, which is formed by cold bending of hot-rolled steel sheets. Its cross-sectional shape resembles the letter "C" and has unique shape characteristics. It is usually composed of a web and two flanges. The web is the main load-bearing part of the C-shaped steel, while the flanges play a role in increasing stability and connecting other components. This shape allows C-shaped steel to have good spatial performance and economy while ensuring structural strength.

[0003] Existing C-shaped steel has some shortcomings in processing and bending. Traditionally, C-shaped steel is bent directly without adjusting the curvature. This limits the processing to C-shaped steel with a fixed curvature, reducing the applicability of the bending device and making the processing relatively unstable. To address these issues, a new bending equipment for adjusting the curvature of C-shaped steel is proposed for improvement and upgrading. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown in the figure, this embodiment provides a bending equipment for adjusting the curvature of C-shaped steel, including a bending machine base 1. A drive motor 6 is fixedly installed inside the upper surface of the bending machine base 1. A bending table 3 is fixedly connected to the output end of the drive motor 6. A guide frustum 61 is rotatably installed at the bottom of the bending table 3 and is fixedly installed on the upper end of the bending machine base 1. A limit frame 7 is fixedly installed on the outer wall of the bending table 3. A threaded rod 72 is threadedly connected inside the limit frame 7 and a limit clamping plate 73 is rotatably installed at one end of the threaded rod 72. An adjustment structure 5 is provided at the upper end of the bending machine base 1 on the rear side of the bending table 3. The adjustment structure 5 includes a mounting seat 51 fixedly installed on the upper end of the bending machine base 1. A cylinder 52 is fixedly installed on the rear side of the mounting seat 51 and is fixedly connected to the limit seat 53 at one end of the cylinder 52. A scale line 57 is fixedly installed on the upper end of the mounting seat 51. A clamping structure 2 is provided at the upper end of the bending machine base 1 on one side of the bending table 3.

[0024] like Figures 3 to 4 As shown, the limiting frame 7 is fixedly installed on the outer wall of the bending table 3. One end of the threaded rod 72 is fixedly connected to the knob 71. The limiting clamp 73 is adapted to the size of the C-shaped steel. The limiting seat 53 is provided with a guide roller 54 inside. The bottom of the limiting seat 53 is fixedly provided with a slider 55. The slider 55 is slidably connected to the slide rail 56 and the slide rail 56 is fixedly installed on the upper end of the mounting base 51. The upper end of the bending machine table 1 is fixedly provided with a control panel 4. The upper end of the mounting base 51 is provided with a limiting rod and one end of the limiting rod is fixedly connected to the upper end of the bending table 3. The inner wall of the bending table 3 is provided with a groove adapted to the C-shaped steel.

[0025] Rotating knob 71 drives threaded rod 72 to rotate, thereby causing limit clamp 73 to engage with and limit the C-shaped steel. Once the C-shaped steel is in position, the cylinder 52 on the drive mounting base 51 is activated, causing the cylinder 52 to move the guide roller 54 on the limit seat 53. When the limit seat 53 moves, the slider 55 slides on the slide rail 56 to limit its movement, which facilitates stable movement of the guide roller 54 to press the C-shaped steel on the bending table 3. The movement of the guide roller 54 driven by the cylinder 52 can be observed through the scale line 57 on the mounting base 51, which facilitates precise control of the position movement of the guide roller 54 and adjustment of the bending degree of the C-shaped steel. The pressure of the cylinder 52 can be adjusted through the control panel 4. For high-strength C-shaped steel, the bending force needs to be increased, while for thinner C-shaped steel, the bending force needs to be reduced to avoid excessive bending or damage to the C-shaped steel.

[0026] like Figure 5 As shown, the clamping structure 2 includes a fixed frame 21 fixedly installed on the upper end of the bending machine table 1. Two bosses 22 are symmetrically fixedly arranged on the upper end of the fixed frame 21, and a bidirectional lead screw 24 is rotatably installed inside the bosses 22. A servo motor 23 is fixedly connected to one end of the bidirectional lead screw 24. The servo motor 23 is fixedly mounted on the fixed frame 21. A first clamping plate 25 and a second clamping plate 26 are respectively threaded to the outer wall of the bidirectional lead screw 24. The positions of the first clamping plate 25 and the second clamping plate 26 are symmetrical to each other. Limiting blocks are fixedly arranged on the upper ends of the first clamping plate 25 and the second clamping plate 26, and the limiting blocks are slidably connected inside the guide plate 27. The two ends of the guide plate 27 are fixedly installed on the inner walls of the two bosses 22.

[0027] The servo motor 23 drives the bidirectional lead screw 24 to rotate, causing the first clamping plate 25 and the second clamping plate 26 to move relative to each other to clamp and fix the C-shaped steel. The flange of the C-shaped steel is engaged with the first clamping plate 25, and the web is pressed against the second clamping plate 26. This allows for clamping and positioning of C-shaped steel of different sizes. A guide plate 27 is provided to limit the position of the first clamping plate 25 and the second clamping plate 26 when they move relative to each other, preventing displacement. The flange of the C-shaped steel is adapted to the size of the first clamping plate 25, and the web is properly fitted to the second clamping plate 26.

[0028] The working principle and process of this utility model are as follows: When C-shaped steel needs to be processed and bent, the operator first pushes the C-shaped steel along the top of the fixing frame 21, and then clamps one end of the C-shaped steel onto the groove on the bending table 3. After the C-shaped steel is positioned, the external power supply is turned on, and the servo motor 23 drives the bidirectional lead screw 24 to rotate, causing the first clamping plate 25 and the second clamping plate 26 to move relative to each other to clamp and fix the C-shaped steel. The flange of the C-shaped steel is clamped with the first clamping plate 25, and the web is pressed against the second clamping plate 26, which helps to clamp and position C-shaped steel of different sizes. At the same time, one end of the C-shaped steel is clamped onto the limiting clamping plate 73. By rotating the knob 71, the threaded rod 72 is rotated, thereby causing the limiting clamping plate 73 to clamp and limit the C-shaped steel. After the C-shaped steel is fixed in position... The cylinder 52 on the drive mounting base 51 is activated, causing the cylinder 52 to move the guide roller 54 on the limit seat 53. When the limit seat 53 moves, the slider 55 slides on the slide rail 56 to limit the movement, which facilitates the stable movement of the guide roller 54 to squeeze the C-shaped steel on the bending table 3. The bending table 3 is rotated by the drive motor 6, thereby bending the C-shaped steel. The movement of the guide roller 54 driven by the cylinder 52 can be observed through the scale line 57 on the mounting base 51, which facilitates precise control of the position movement of the guide roller 54. According to the bending requirements of the C-shaped steel, the distance between the guide roller 54 and the outer extrusion position of the C-shaped steel is adjusted. The control panel 4 precisely adjusts the pressure of the cylinder 52 according to the material, thickness and preset bending degree of the C-shaped steel, thereby controlling the bending force and adjusting the bending degree of the C-shaped steel.
