[0002] Steel bending devices are common equipment used to bend steel pipes, steel plates, or steel bars. In related technologies, steel bending devices include a frame, a forming roller, and a drive roller. The forming roller and drive roller are located on the frame. When steel needs to be bent, the steel is placed on the frame, and the forming roller abuts against one side of the steel, while the drive roller abuts against and pushes the other side of the steel.

[0056] The following is for reference. Figures 1 to 7 This invention describes a steel bending device according to an embodiment of the present invention.

[0057] refer to Figures 1 to 7 As shown, the steel bending device according to an embodiment of the present utility model includes a frame 100, a forming roller replacement mechanism 30, a first bending mechanism 60, and a second bending mechanism 20.

[0058] The frame 100 has a mounting groove 101. For example, the mounting groove 101 can be located at the top of the frame 100. The mounting groove 101 is used to place the steel 800 and allow the steel 800 to extend along the length of the mounting groove 101.

[0059] The first bending mechanism 60 and the second bending mechanism 20 are clamping in shape and are respectively set on both sides of the bending part of the steel 800 to be bent on the frame.

[0060] The first bending mechanism 60 includes a first bending mechanism rotating arm (i.e., a second rotating arm 601) and a first bending mechanism rotating arm drive mechanism (i.e., a fourth drive unit 602). One end of the second rotating arm 601 is rotatably connected to the frame 100, and the other end is connected to a drive roller 600. The drive roller 600 is movably mounted on the frame 100; for example, the drive roller 600 can move along a straight line or along a circular arc. The fourth drive unit 602 rotates the second rotating arm 601 relative to the frame 100, as detailed below:

[0061] refer to Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the frame 100 is provided with two rotatable second rotating arms 601, which are arranged along the width direction of the mounting groove 101. The rotation axis of the second rotating arms 601 extends along the width direction of the mounting groove 101. The two ends of the drive roller 600 are respectively connected to the two second rotating arms 601. A fourth drive unit 602 is provided between the second rotating arms 601 and the frame 100. The fourth drive unit 602 is used to drive the second rotating arms 601 to rotate. For example, the fourth drive unit 602 can be set as a hydraulic cylinder. When the fourth drive unit 602 is activated, it can drive the second rotating arms 601 to rotate. The second rotating arms 601 can then drive the drive roller 600 to move. The drive roller 600 can then abut against and push the steel 800 to bend and form around the forming roller 500 between the two mounting frames 200, making the operation more convenient and the forming effect better.

[0062] It should be noted that the fourth drive unit 602 can also be a cylinder, an electric push rod, or other suitable drive structure. Furthermore, the drive roller 600 can also be driven in other ways; for example, its movement can be directly controlled by a motor-screw mechanism.

[0063] The second bending mechanism 20 is rotatably mounted on the frame 100 relative to the frame, receives the forming roller 500 from the forming roller replacement mechanism 30 and places the forming roller across the frame, and includes a pair of mounting brackets 200 mounted on both sides of the frame 100 and arranged opposite each other, that is, the two mounting brackets 200 are located on the frame 100 and on both sides of the width direction of the mounting groove 101.

[0064] The mounting bracket 200 includes a mounting base 201, a plug-in part 202, and a plug-in drive mechanism 203 (i.e., a second drive part 203); the plug-in part 202 is driven by the second drive part 203 and is connected to the mounting base 201 in a piston-like manner; the two opposing plug-in parts 202 form a forming roller mounting position.

[0065] The mounting bracket 200 also includes a second bending mechanism rotating arm 204 (i.e., the first rotating arm 204) and a second bending mechanism rotating arm drive mechanism 205 (i.e., the third drive unit 205); one end of the first rotating arm 204 is rotatably connected to the frame 100, and the other end is connected to the mounting base 201; the third drive unit 205 drives the first rotating arm 204 to rotate relative to the frame 100.

[0066] Specifically as follows:

[0067] refer to Figure 6 and Figure 7 As shown, in some embodiments of this utility model, the mounting frame 200 includes a mounting base 201 and a plug-in portion 202. The plug-in portion 202 is disposed on the mounting base 201 and can be adjusted and moved along the width direction. When one of the forming rollers 500 is located between two mounting frames 200, the two plug-in portions 202 can move in opposite directions to plug into the two mounting shafts 501 of the forming roller 500 respectively. For example, the end face of the mounting shaft 501 can be provided with a plug hole 502, and the plug-in portion 202 can be set as a cylinder. When one of the forming rollers 500 is located between two mounting frames 200, the two plug-in portions 202 move in opposite directions, and the two plug-in portions 202 can be inserted into the two plug holes 502 respectively, thereby realizing the connection between the forming roller 500 and the mounting frame 200. When it is necessary to disassemble the forming roller 500, the two plug-in portions 202 can be moved away from each other. The operation is simple and convenient, saving time and effort.

[0068] It should be noted that the plug part 202 may also have a plug hole 502, and the mounting shaft 501 may be inserted into the plug hole 502.

[0069] refer to Figure 6 and Figure 7As shown, in some embodiments of this utility model, the mounting bracket 200 further includes a second driving part 203. The second driving part 203 is disposed on the mounting base 201 and connected to the insertion part 202 to drive the insertion part 202 to move. For example, the second driving part 203 can be configured as a hydraulic cylinder, with the insertion part 202 connected to the piston of the second driving part 203. Activating the second driving part 203 allows it to control the movement of the insertion part 202, resulting in a higher degree of automation, simpler and more convenient operation, and greater time and labor savings.

[0070] It should be noted that the insertion part 202 can also be moved manually. Once the insertion part 202 is moved to the insertion hole 502, it can be locked by a limit pin to prevent the insertion part 202 from moving arbitrarily. In addition, the second drive part 203 can also be a cylinder, an electric push rod, or other suitable drive structure.

[0071] refer to Figure 6 As shown, in some embodiments of this utility model, the mounting frame 200 further includes a first rotating arm 204 and a third driving unit 205. The first rotating arm 204 is rotatably connected to the frame 100, and the rotation axis of the first rotating arm 204 extends along the width direction. The mounting seat 201 is disposed on the first rotating arm 204, and the third driving unit 205 is disposed between the first rotating arm 204 and the frame 100 to drive the first rotating arm 204 to rotate. For example, the third driving unit 205 can be configured as a hydraulic cylinder. Activating the third driving unit 205 will drive the first rotating arm 204 to rotate, and the first rotating arm 204 will then move the mounting seat 201. Thus, when installing the forming roller 500, the position of the mounting seat 201 can be adjusted appropriately, making it easier for the rotating drum 300 to rotate so that the corresponding forming roller 500 is positioned between the two mounting seats 201. Furthermore, after the forming roller 500 is installed on the two mounting seats 201, the position of the mounting seats 201 can be adjusted so that the forming roller 500 between the two mounting seats 201 just abuts against the steel 800, thereby improving the bending and forming effect of the steel 800 and making it applicable to steel 800 of different thicknesses, thus improving its practicality. It should be noted that the third drive unit 205 can also be a cylinder, an electric push rod, or other suitable drive structure.

[0072] The forming roller replacement mechanism 30 includes a rotating drum 300, a clamping member 400, and a forming roller 500;

[0073] The rotating drum 300 can be cylindrical and is mounted on the frame 100 around its own axis. For example, the rotating drum 300 can be driven to rotate by a motor or manually. The axis of the rotating drum 300 extends along the width direction of the mounting groove 101.

[0074] Multiple clamping members 400 are disposed on the outer peripheral wall of the rotating cylinder 300 and arranged along the circumference of the rotating cylinder 300. The number of clamping members 400 varies according to the needs of the application scenario. In this embodiment, four clamping members 400 can be provided, and the four clamping members 400 can be evenly arranged along the circumference of the rotating cylinder 300.

[0075] refer to Figures 1 to 3 As shown, in some embodiments of this utility model, the clamping member 400 includes two clamps 401, which are arranged along the axial direction of the rotating drum 300. The forming roller 500 has mounting shafts 501 at both ends, and the two mounting shafts 501 are respectively clamped by the two clamps 401. The clamps 401 can clamp the mounting shafts 501 at both ends of the forming roller 500 and can also release the clamps. Specifically, when the forming roller 500 is not needed, the two mounting shafts 501 at both ends of the forming roller 500 are clamped onto the two clamps 401 of the clamping member 400. When the forming roller 500 needs to be used, the rotating drum 300 is rotated so that the corresponding forming roller 500 is positioned between the two mounting brackets 200, and then the two clamps 401 are released from clamping the mounting shafts 501. The operation is simple, convenient, and saves time and effort.

[0076] It should be noted that the clamping member 400 can also be other structures. For example, only one clamp 401 can be provided, which directly clamps the middle position of the forming roller 500.

[0077] refer to Figure 4 As shown, in some embodiments of this utility model, the clamp 401 includes a mounting arm 402, a fixing part 403, a movable part 404, and a first driving part 406. The mounting arm 402 is disposed on the outer peripheral wall of the rotating drum 300, the fixing part 403 is disposed on the mounting arm 402, and the movable part 404 is hinged to the mounting arm 402. An openable clamping space 405 is formed between the movable part 404 and the fixing part 403. The clamping space 405 is used to mount the mounting shaft 501. The first driving part 406 is disposed between the movable part 404 and the mounting arm 402 to drive the movable part 404 to rotate. For example, one end of the mounting arm 402 in the longitudinal direction can be connected to the outer peripheral wall of the rotating drum 300, and the fixing part 403, the movable part 404, and the first driving part 406 can be disposed at the end of the mounting arm 402 away from the rotating drum 300. The first driving part 406 can be configured as a hydraulic cylinder.

[0078] When clamping the forming roller 500, the mounting shaft 501 of the forming roller 500 is inserted into the clamping space 405. Then, the first drive unit 406 is activated, driving the movable part 404 to rotate towards the fixed part 403, causing the clamping space 405 to gradually close. The movable part 404 and the fixed part 403 then cooperate to clamp the mounting shaft 501, thereby clamping the forming roller 500. When it is necessary to release the clamping of the forming roller 500, the first drive unit 406 is activated, driving the movable part 404 to rotate away from the fixed part 403, causing the clamping space 405 to gradually open. The mounting shaft 501 can then be moved out of the clamping space 405, thereby releasing the clamping of the forming roller 500. The structure is simple and the operation is convenient.

[0079] It should be noted that the first drive unit 406 can also be a cylinder, an electric push rod, or other suitable drive structure. In addition, the clamp 401 can also be other common clamp structures, which will not be described in detail here.

[0080] refer to Figure 4 As shown, in some embodiments of this utility model, the surface of the fixed part 403 near the movable part 404 is configured as a concave arc surface 407, and the movable part 404 near the fixed part 403 is provided with an elastic abutment block 408. For example, the radius of the concave arc surface 407 can be adapted to the radius of the forming roller 500, the elastic abutment block 408 can be made of elastic rubber or elastic plastic, and the surface of the elastic abutment block 408 near the fixed part 403 can be configured as a concave surface.

[0081] In this embodiment, the forming roller 500 is clamped more securely, the clamping effect is better, and the forming roller 500 is less likely to be damaged, thus improving its practicality.

[0082] refer to Figure 3 and Figure 4 As shown, in some embodiments of this utility model, an opening 409 is formed between the end of the fixed part 403 away from the mounting arm 402 and the end of the movable part 404 away from the mounting arm 402. When the clamp 401 is located on the side of the rotating drum 300 near the mounting bracket 200, the opening 409 faces downward. For example, when the mounting bracket 200 is located at the lower left of the rotating drum 300, the opening 409 on the clamp 401 located on the left and below the rotating drum 300 can face approximately downward. In this way, when the forming roller 500 is installed between the two mounting brackets 200, it is easier for the forming roller 500 to separate from the clamp 401, avoiding jamming.

[0083] Multiple forming rollers 500 are clamped by multiple clamping members 400. For example, when there are four clamping members 400, there can also be four forming rollers 500. The clamping members 400 can clamp both ends of the forming rollers 500. The axis of the forming rollers 500 extends along the width direction of the mounting groove 101. At least some of the forming rollers 500 have different radii. For example, all the forming rollers 500 may have different radii, or some of the forming rollers 500 may have different radii and some may have the same radii. The radius of the forming rollers 500 corresponds to the radius of the inner rounded corner that the steel 800 needs to be bent to form.

[0084] During use, by driving the rotating drum 300 to rotate, different forming rollers 500 can be positioned between two mounting frames 200, so that the two ends of the forming rollers 500 can be respectively mounted on the two mounting frames 200.

[0085] When the steel 800 is placed in the mounting groove 101, the forming roller 500 between the two mounting frames 200 can abut against one side of the steel 800, and the driving roller 600 can abut against and push the other side of the steel 800 during the movement, so that the steel 800 bends and deforms around the forming roller 500 between the two mounting frames 200.

[0086] In this embodiment, the radius dimensions of the multiple forming rollers 500 can be the same as several common radius dimensions of the inner rounded corners formed after bending the steel 800. When the steel 800 needs to be bent, the steel 800 is placed on the placement groove, and the rotating drum 300 is rotated so that the forming rollers 500 with the corresponding radius dimensions are located between the two mounting frames 200. Then, the forming rollers 500 are separated from the corresponding clamping parts 400, and the two ends of the forming rollers 500 are respectively connected to the two mounting frames 200. Then, the forming rollers 500 between the mounting frames 200 are brought into contact with one side of the steel 800. Finally, the drive roller 600 is moved, and the drive roller 600 abuts against and pushes the other side of the steel 800, so that the steel 800 is bent and deformed around the forming rollers 500 between the two mounting frames 200. According to the steel bending device of this utility model embodiment, when it is necessary to bend steel 800 to form inner rounded corners of different radii, the rotating drum 300 is rotated to install forming rollers 500 of different radii between two mounting frames 200. The operation is simple and convenient, and only one steel bending device is needed instead of setting up multiple steel bending devices, which reduces costs and occupies less space.

[0087] Furthermore, considering the limitation on the length of the bent portion of the steel to be bent, a length-fixing component 700 is also provided in this embodiment, which includes a lead screw 701 and a length-fixing plate 702; the lead screw 701 is rotatably mounted on the frame 100; the length-fixing plate 702 is threadedly connected to the lead screw 701 and reciprocates on the frame 100 driven by the rotation of the lead screw 701, as detailed below:

[0088] refer to Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the steel bending device further includes a length-fixing component 700. The length-fixing component 700 includes a lead screw 701 and a length-fixing plate 702. The lead screw 701 is rotatably mounted on the frame 100 and extends along the length direction of the mounting groove 101. The length-fixing plate 702 is disposed on the frame 100 and can be slidably adjusted along the length direction of the mounting groove 101. The length-fixing plate 702 is threadedly connected to the lead screw 701. For example, the frame 100 may be provided with a guide rail that extends along the length direction of the mounting groove 101. The length-fixing plate 702 is slidably mounted on the guide rail. The length-fixing plate 702 may be provided with a threaded hole, and the lead screw 701 is threadedly connected to the threaded hole.

[0089] Before bending the steel 800, the lead screw 701 is rotated. Since the lead screw 701 is threadedly connected to the length-fixing plate 702, and the length-fixing plate 702 is slidably connected to the frame 100, the lead screw 701 can drive the length-fixing plate 702 to move along the length direction of the mounting groove 101. This allows adjustment of the distance between the length-fixing plate 702 and the forming rollers 500 between the two mounting brackets 200. After placing the steel 800 in the mounting groove 101, one end of the steel 800 can abut against the length-fixing plate 702. In this way, the length of the bent portion of the steel 800 can be determined. By moving the length-fixing plate 702, different required bending lengths of the steel 800 can be fixed. The quality of the bent steel 800 is better, and its practicality is improved.

[0090] It should be noted that the lead screw 701 can be rotated by a motor or manually. Furthermore, the length direction mentioned in this invention refers to the length direction of the mounting groove 101, and the width direction refers to the width direction of the mounting groove 101.

[0091] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
