Description

Technical Field

[0001] The utility model relates to the technical field of angle steel bending devices, in particular to a bending device for angle steel production. Background Art

[0002] Steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other. It can be divided into equal-leg angle steel and unequal-leg angle steel. The two sides of equal-leg angle steel are equal in width. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses. Angle steel is a carbon structural steel for construction. It is required to have good weldability, plastic deformation performance and certain mechanical strength during use. The raw material billet for producing angle steel is low-carbon square billet, and the finished angle steel is hot-rolled, normalized or hot-rolled.

[0003] For example, a bending device for angle steel production with announcement number CN214391789U includes a conveying and bending mechanism and a limiting mechanism for limiting the position of the angle steel raw material, the conveying and bending mechanism includes a base plate and a support frame 1, the top of the support frame 1 is fixedly installed with a hydraulic telescopic rod 1, the telescopic end of the hydraulic telescopic rod 1 is fixed with the pressure wheel bracket, the inner side of the pressure wheel bracket is rotatably connected with the pressure wheel, the inner wall of the support frame 1 is rotatably connected with a groove wheel, the support frame 1 is fixedly installed with a motor 1 with an output shaft connected with the groove wheel, the top of the base plate and the two sides of the support frame 1 are fixedly connected with a support frame 2, the top of the support frame 2 is fixedly installed with a hydraulic telescopic rod 2, and the telescopic end of the hydraulic telescopic rod 2 is fixed with a conveying wheel bracket.

[0004] The above-mentioned device passes the angle steel raw material to be bent between the pressure wheel and motor one, and between the transmission wheel one and transmission wheel two at the same time, and starts motor one and motor two to drive the groove wheel and transmission wheel two to rotate respectively, so as to transmit and press the bent angle steel. Starting hydraulic telescopic rod one or hydraulic telescopic rod two can respectively drive the pressure wheel and transmission wheel one to rise and fall, so as to adapt to the angle steel. However, the above-mentioned device can only be used for angle steel of one angle, and has relatively low limitations in production. In production, angle steels are generally flat when leaving the factory, and the required bending angle needs to be changed many times later. The above-mentioned device has poor adaptability in this regard. Utility Model Content

[0005] The utility model aims to provide a bending device for angle steel production to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bending device for angle steel production, comprising a bending platform, a plurality of support columns are arranged at the lower end of the bending platform, and a driving motor is arranged on the lower left surface of the bending platform, and a pushing device is arranged at the corresponding position of the upper surface of the bending platform, power transmission lines are arranged on both sides of the pushing device and connected to the upper and lower support frames, and a support plate is arranged on the support frame, and a telescopic end is arranged at the lower end of the support plate, an angle adjuster is arranged at the lower end of the telescopic end, and pull rods are arranged on both sides of the angle adjuster, and a bending plate is arranged at the lower end of the pull rod.

[0007] Preferably, the bending plate is actively embedded in the placement column, and the placement column is arranged at the lower end of the angle adjuster, and placement ends are arranged at both ends of the placement column.

[0008] Preferably, the pushing device is connected to one end of the drum pushing pile by a connecting bracket, and the other end of the drum pushing pile is connected to the synchronizer by a connecting column, and a curved pad is placed on the upper end of the drum pushing pile.

[0009] Preferably, a placement groove is arranged in the middle of the drum push pile, and a movable column is arranged inside the placement groove, and a bending force-bearing plate is actively inserted on the surface of the movable column.

[0010] Preferably, a moving groove is arranged at the lower end of the drum-pushing pile, and the lower end of the drum-pushing device is connected to a moving column, and a meshing gear is arranged on the outer surface of the moving column.

[0011] Preferably, a meshing spur tooth is provided at one end of the movable groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Compared with other bending devices for angle steel production, considering that the angle steels just produced are all in a flat shape, the subsequent angle steel forming requires a variety of angles and sizes, and the multi-angle requirements make it difficult for those fixed-angle angle steel bending devices to adapt. This device installs a bending force plate that can adjust the angle on the bending platform. The force plate can change its angle property, so that the device can effectively change the bending of the angle steel according to needs.

[0014] 2. In addition, the bending plate placed at the upper end of the device is also provided with an angle adjuster that can follow the angle change, so that the bending angles of the upper and lower ends are the same, the degree of engagement is higher during bending, and the bending force plate at the lower end is pushed inward by the drum push piles at both ends to change the bending force plate. The curved pad at the top can continuously contact and bear force according to the angle change of the plate, ensuring the stability of both ends during bending operation.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 , the utility model provides a technical solution:

[0022] Figure 1 This is an overview of the right side of the device. The main body is a bending platform 1. A plurality of support columns 2 are arranged at the lower end of the bending platform 1 as the overall support effect of the entire device. A driving motor 3 is arranged on the lower left surface of the bending platform 1 to provide the required electrical energy support for the upper components. At the same time, a pushing device 4 is arranged at the corresponding position of the upper surface of the bending platform 1. The placement of the pushing device 4 pushes the connected components to effectively move and control them. Transmission lines are arranged on both sides of the pushing device 4 and connected to the upper and lower end support frames 6, and a support plate 5 is arranged on the support frame 6. The placement of the transmission line provides the required kinetic energy for the device connected to the lower side of the support plate 5.

[0023] Figure 2This is a front overview of the device, the main body of which is a pushing device 4, which is connected to one end of the drum push pile 7 by a connecting bracket, and the other end of the drum push pile 7 is connected to a synchronizer 9 by a connecting column. The synchronizer 9 is internally provided with three gear transmissions, one of which is arranged in the middle and the others are symmetrical to each other, which can mainly allow the connecting column arranged at the upper end to maintain the same frequency when moving, and ensure that the positions of the drum push piles 7 at both ends move evenly. At the same time, a curved pad is arranged at the upper end of the drum push pile 7, considering that the bending force plate 8 will cause the position of the force point to change with the adjustment of the angle, the ordinary force plate will therefore cause uneven force or a more concentrated force point, and the placement of the curved pad ensures stability when the force is applied, a placement groove is arranged in the middle of the drum push pile 7, and a movable column is arranged inside the placement groove, and at the same time, the bending force plate 8 is actively inserted on the surface of the movable column, and the effect of the active insertion can allow the bending force plate 8 to change its angle under the push of the drum push pile 7;

[0024] Figure 3 It is a small-angle left side view of the device, the main body is a support plate 5, and a telescopic end 12 is set at the lower end of the support plate 5. The telescopic end 12 is set for the bending operation of the device, providing a downward force for the lower bending plate 10 to allow the angle steel to bend under heavy pressure. An angle adjuster 13 is placed at the lower end of the telescopic end 12, and pull rods 11 are set on both sides of the angle adjuster 13. At the same time, a bending plate 10 is placed at the lower end of the pull rod 11. The degree of retraction and extension of the pull rod 11 controls the angle of the bending plate 10. The middle part of the bending plate 10 is actively embedded in the placement column, and the positions of the two embedded are different to prevent the phenomenon of staggered between them. The placement column is set at the lower end of the angle adjuster 13, and placement ends are set at both ends of the placement column. The setting of the placement end makes the placement column stable on both sides;

[0025] Figure 4 This is a top view of the device, in which the main body is a drum-pushing pile 7, a movable groove is arranged at the lower end of the drum-pushing pile 7, and the lower end of the drum-pushing device is connected to a movable column 14, and a meshing gear 16 is arranged on the outer surface of the movable column 14, and a meshing spur tooth 15 is arranged at one end of the movable groove. The arrangement of the meshing gear 16 and the meshing spur tooth 15 ensures that the movement of the movable column 14 is a planar movement, avoiding angular deviation or tilting of the movable column 14 due to friction.

[0026] During actual use, first turn on the drive motor 3, control the pushing device 4 as needed, push the connecting bracket to adjust the drum push pile 7, push the bending force plates 8 on both sides to the required position to achieve the required angle, place the newly produced angle steel on the upper end, use the angle adjuster 13 to change the telescopic length of the pull rod 11 to adjust the angle of the upper bending plate 10 to ensure the uniformity of the angles of the bending parts at the upper and lower ends, start the bending operation, and use the downward pressure of the telescopic end 12 to bend the angle steel.
