[0002] Angle steel, as a commonly used metal profile, is widely used in building frames, mechanical supports, hardware components and other fields. During the transportation, storage or use of angle steel, it is prone to local bending deformation due to external impact, squeezing and other factors. In particular, the corners and ends of the angle steel are affected by bending deformation, which not only affects the appearance, but also leads to a decrease in installation accuracy, or even makes it impossible to use normally.

[0003] In existing technology, angle steel is placed on a hydraulic straightening machine, and a hydraulic rod device is used to drive the extrusion head to extrude the bent parts of the angle steel, thereby straightening the angle steel to a flat position.

They are only suitable for the overall straightening of large batches and large-sized angle steel. For small-area and local bending leveling, they have problems such as cumbersome operation, high energy consumption, and poor flexibility. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In practical use, although hydraulic straightening machines have a good leveling effect, they are large in size, heavy in weight, inconvenient to move, and have high equipment costs. They are only suitable for the overall straightening of large batches and large-sized angle steel. For small-area and local bending leveling, they have problems such as cumbersome operation, high energy consumption, and poor flexibility.

[0017] In view of this, the present invention provides a tool for local bending and leveling of angle steel, which solves the problem that, in actual use, although hydraulic straightening machines have good leveling effect, they are large in size, heavy in weight, inconvenient to move, and have high equipment cost. They are only suitable for overall straightening of large batches and large-sized angle steel. For small-area and local bending and leveling, they have problems such as cumbersome operation, high energy consumption and poor flexibility.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Example 1: By Figure 1-4 As can be seen, a tool for partially bending and leveling angle steel includes a worktable 1, a pad 2 fixedly connected to the top of the worktable 1, and a hammer 3 disposed above the pad 2. The tool also includes a drive device 4, a fixing component 5, and a limiting device 6. The drive device 4 is installed on the top of the hammer 3; two sets of fixing components 5 are provided, respectively disposed on both sides of the hammer 3; the limiting device 6 is installed at the bottom of the fixing component 5. The drive device 4 drives the hammer 3 to move, the fixing component 5 fixes the workpiece, and the limiting device 6 adjusts the position of the fixing component 5. In the specific implementation process, it is worth noting that the pad 2 is a solid steel plate and is fixed on the top of the workbench 1. Moreover, the top of the pad 2 is a flat surface, which makes the angle steel straighten faster under the hammer 3. At the same time, the hammer 3 will continuously strike the angle steel under the drive of the drive device 4 to straighten its bent parts. During the hammering and straightening process, the fixing component 5 is used to fix the angle steel, which can prevent it from shaking during the hammering process. Under the control of the limiting device 6, the fixing component 5 can be convenient to fix the angle steel, and can fix angle steel of different sizes and models, thus improving the overall practicality of the device. Furthermore, the drive device 4 includes a support rod 41, a fixing frame 42, a limiting frame 43, and a reciprocating assembly 44. The support rod 41 is threaded to the top of the hammer 3; the fixing frame 42 is sleeved on the outer wall of the support rod 41 and fixedly connected to the top of the worktable 1; the limiting frame 43 is sleeved on the outer wall of the support rod 41 and fixedly connected to the top of the inner wall of the fixing frame 42; the reciprocating assembly 44 is installed on the top of the support rod 41; wherein, the reciprocating assembly 44 drives the support rod 41 and the hammer 3 to reciprocate and strike, the limiting frame 43 stabilizes the support rod 41 during operation, and the fixing frame 42 supports the reciprocating assembly 44. In the specific implementation process, it is worth noting that the reciprocating component 44 drives the support rod 41 to drive the hammer 3 to continuously strike the angle steel and correct its bent part. When the support rod 41 moves up and down, the fixing frame 42 and the limiting frame 43 can limit the support rod 41 to ensure the stability of the support rod 41 when it moves up and down. Furthermore, the reciprocating assembly 44 includes a connecting rod 441, a turntable 442, a bent plate 443, and a servo motor 444. The connecting rod 441 is rotatably connected to the top of the support rod 41 via a pin; the turntable 442 is rotatably connected to the top of the connecting rod 441 via a pin; the bent plate 443 is fixedly connected to the top of the fixed frame 42, and its outer wall is rotatably connected to the outer wall of the turntable 442 via a sealed bearing; the servo motor 444 is fixedly connected to the outer wall of the bent plate 443, and its output end is fixed through one end of the bent plate 443 via a sealed bearing. It is connected to the outer wall of the turntable 442; wherein, through the cooperation of the connecting rod 441 and the turntable 442, the servo motor 444 drives the support rod 41 to move back and forth, the bending plate 443 supports the turntable 442, and a threaded rod is fixed on the top of the hammer 3. The hammer 3 is fixedly installed on the bottom of the support rod 41 by a threaded connection. The hammer 3 is pre-designed to have different heights, so that when the stroke of the reciprocating component 44 remains unchanged, the angle steel with different wall thicknesses can be straightened by replacing the hammer 3 with different heights. In the specific implementation process, it is worth noting that by using a connecting rod 441 to connect the turntable 442 and the support rod 41, when the servo motor 444 drives the turntable 442 to rotate, it will cause the connecting rod 441 to swing around its connection position with the support rod 41. Since the top of the connecting rod 441 is rotatably connected to the outer wall of the turntable 442 via a pin, the connection position of the connecting rod 441 with the turntable 442 will rotate around the turntable 442. Thus, under the constraint of both ends of the connecting rod 441, the connecting rod 441 drives the support rod 41 to move up and down reciprocally. This allows the striking hammer 3 to continuously strike and correct the angle steel. Furthermore, this can be achieved by controlling the servo motor 444 via an external controller, thereby realizing rapid correction of the angle steel. The model of the servo motor 444 is not limited, as long as it meets the actual use. The material of the connecting rod 441 is alloy or spring steel. During the straightening process, because the angle steel straightening part bends upward, when the servo motor 444 rotates and drives the hammer 3 to move downward, it is obstructed by the protruding part of the angle steel. At this time, the connecting rod 441 undergoes elastic deformation under force. In this way, the bending of the connecting rod 441 compensates for the stroke obstruction caused by the protruding angle steel to the hammer 3, and avoids the servo motor 444 from jamming. Although the connecting rod 441 bends under force, most of the striking force can still be delivered to the bent part of the angle steel through the hammer 3. Multiple strikes can improve the flatness of the bent part of the angle steel, ensure the straightening effect, and at the same time avoid the occurrence of jamming of the servo motor 444. Example 2: From Figure 1-4It is known that the fixing component 5 includes a support plate 51, a column 52, a pressure plate 53, and a collar 54. The support plate 51 is movably connected to the top of the worktable 1; the column 52 is fixedly connected to the top of the support plate 51; the pressure plate 53 is disposed above the support plate 51; the collar 54 is fixedly connected to the outer wall of the pressure plate 53 and sleeved on the outer wall of the column 52, and its inner wall is fixedly connected to the outer wall of the column 52 by bolts; wherein, through the cooperation of the collar 54 and the column 52, the pressure plate 53 and the support plate 51 fix the workpiece. In the specific implementation process, it is worth noting that there are two sets of fixing components 5, which are respectively set on the top sides of the workbench 1. Each set of fixing components 5 is symmetrically arranged, so that the fixing components 5 at the front and back of the top of the workbench 1 can be fixed individually. When fixing the angle steel in different directions, the uneven side is placed on the support plate 51 and the pad 2, and the opening is aligned with the pressure plate 53 on the fixing component 5. This avoids the pressure plate 53 pressing on the vertical section of the angle steel, which makes the fixing stable and prevents the angle steel from being damaged or deformed. When fixing it, the bolts on the collar 54 are removed, so that the pressure plate 53 is pressed against the plane of the bent side of the angle steel under the action of gravity. The bolts on the collar 54 are then tightened to fix the position of the pressure plate 53. This makes it convenient to fix the workpiece. It is understood that the technical solution described in this embodiment is only applicable to cases where the angle steel is slightly bent in a local area. The degree of bending does not affect the effective fixing by the fixing component 5. If the angle steel is bent more severely, large straightening equipment needs to be considered. The key technical advantages of the angle steel local bending leveling tool provided by this solution are simple operation, small overall size of the device, it can work as soon as it is powered on, does not rely on a hydraulic system, has flexible application scenarios, is convenient to transport, and is low in cost. Furthermore, the limiting device 6 includes a slide groove 61, a slider 62, and a fixing block 63. The slide groove 61 is formed on the top of the worktable 1; the slider 62 is slidably engaged with the inner wall of the slide groove 61, and its top is fixedly connected to the bottom of the support plate 51; the fixing block 63 is fixedly connected to the outer wall of the support plate 51, and the outer wall is fixedly connected to the top of the worktable 1 by bolts; wherein, through the cooperation of the slide groove 61 and the slider 62, the position of the support plate 51 is adjustable, and the fixing block 63 fixes the position of the support plate 51. In the specific implementation process, it is worth noting that the slide groove 61 and the slider 62 are trapezoidal in shape. This ensures that the slider 62 slides stably in the slide groove 61, and also ensures that the slider 62 will not fall off the slide groove 61. When fixing larger or smaller angle steel, the position of the fixing component 5 is adjusted by the slider 62 and the slide groove 61. After the adjustment is completed, the fixing block 63 is fixed on the worktable 1, which ensures stability when straightening the angle steel.
