[0001] The invention relates to the technical field of steel material manufacturing, and in particular to an angle steel bending device for steel structure construction. Background Art

[0002] At present, with the development of manufacturing industry, angle steel is widely used in the construction industry. Angle steel belongs to carbon structural steel for construction. It is a simple cross-section steel. It is mainly used for metal components and factory frames. When using angle steel, it is necessary to bend the angle steel. Angle steel can be composed of various load-bearing components according to different structures, and can also be used as connectors between components. Therefore, it plays an important role in building components.

[0003] At present, when bending the angle steel, it is necessary to fix the bending position of the angle steel, and then apply a downward force to the position where the angle steel needs to be bent, so as to complete the bending operation of the angle steel. However, in the bending process of the existing equipment, the contact position between the extrusion plate and the angle steel also changes when the angle steel is bent, resulting in relative sliding between the extrusion plate and the surface of the angle steel, causing abnormal scratches on the surface of the angle steel, thereby affecting the bending quality of the angle steel.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0019] like Figure 1 , Figure 3 and Figure 6 As shown, in one embodiment, a device for bending angle steel for steel structure construction is provided, the device comprising: The main frame 1 includes a mounting platform 101 disposed on the main frame 1 , a fixed slideway 102 is fixedly mounted on the surface of the mounting platform 101 , and a supporting slide plate 103 is fixedly mounted on the surface of the mounting platform 101 ; Bending mechanism 2: comprising two rotating disks 203 mounted on the mounting platform 101, a follower rod 202 is fixedly mounted on the surface of each rotating disk 203, and a bending plate 201 is fixedly mounted on the surface of the follower rod 202; Transverse movement mechanism 4: used to adjust the bending position of the angle steel through the driving mechanism 5; Clamping mechanism 6: used to clamp and position the bending position of the angle steel; Positioning mechanism 8: used to position and tighten the angle steel.

[0020] In practical application of the embodiment of the present invention, when the angle steel is bent, Figure 1 As shown, at this time, the angle steel is placed on the positioning mechanism 8 through an external clamping device. At this time, the angle steel is clamped by the positioning mechanism 8. After clamping, the transverse movement mechanism 4 is driven to move by the driving mechanism 5 to determine the bending position of the angle steel. At the same time, the movement of the transverse movement mechanism 4 drives the rotating disk 203 to move horizontally synchronously, thereby driving the two bending plates 201 to move to the two ends of the angle steel respectively through the connection of the mechanism to reach the position where the angle steel needs to be bent, thereby achieving the purpose of automatically adjusting the bending position. When the bending position is reached, as shown in FIG. Figure 3 and Figure 6 As shown, at this time, the bending plate 201 is driven to move downward by the action of the clamping mechanism 6, and the bending position of the angle steel is fixed and clamped under the action of the clamping mechanism 6, thereby avoiding the abnormality of local bending deformation. When the bending part of the angle steel is clamped, the rotating disk 203 starts to rotate. The rotation of the rotating disk 203 drives the bending plate 201 to rotate synchronously, thereby bending the angle steel. At the same time, during the rotation process, the bending plate 201 always maintains parallel contact with the angle steel and is always located at the same position of the angle steel, thereby avoiding the abnormality of the angle steel being scratched in appearance during the bending process.

Figure 3 As shown, the connecting action of the mechanism drives the connecting rod 403 to move in the horizontal direction, and then drives the bending plate 201 to move in the horizontal direction through the rotating disk 203. At the same time, the transverse connecting rod 401 drives the fulcrum block 404 to move in the horizontal direction. At this time, the bending plate 201 and the fulcrum block 404 move to the bending position of the angle steel, thereby achieving the purpose of automatically adjusting the bending position.
