Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine for steel structures. Background Art

[0002] Bending machines are machines that process cold-bent steel bars and other materials, and are widely used in construction, bridges, and other fields. They are mainly used to bend steel bars, round steel, angle steel, and other materials, and can produce various curved shapes to meet the needs of different occasions.

[0003] Bending machines are often used when steel structure materials need to be bent, but existing bending machines have the following problems during use:

[0004] First, the center column on the bending machine is used to determine the inner diameter of the steel structure bending, and the center column is usually directly fixed on the rotating table, which makes it impossible to adjust the outer diameter of the center column at will, making it difficult to adapt to the bending requirements of different steel structures;

[0005] In addition, when the rotating table controls the rotation of the traction column to drive the steel structure to bend, once the steel structure is placed in an uneven position, the bent end of the steel structure will warp up, requiring it to be reset later, thus affecting the product's qualification. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the utility model provides a bending machine for steel structures, which overcomes the shortcomings of the existing technology and effectively solves the problem that it is difficult to adapt to the bending requirements of different steel structures and the problem that the steel structure will warp due to uneven placement.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A bending machine for steel structures, comprising a chassis, a rotating table rotatably connected to the top outer wall of the chassis, a disc seat welded to the top outer wall of the rotating table, a center sleeve placed on the top outer wall of the disc seat, an internally threaded sleeve welded to the top outer wall of the disc seat, a first screw rod screwed to the inner wall of the internally threaded sleeve, and an anti-slip sheet welded to the top of the outer wall of the first screw rod;

[0009] A traction column is welded to the outer wall of the top of the rotating table, and the outer wall of the top of the rotating table is located on one side of the traction column and is rotatably connected to a second screw rod. A pressure plate is screwed to the outer wall of the second screw rod, and symmetrically distributed pressure blocks are welded to the outer wall of one side of the pressure plate.

[0010] Preferably, an output column is welded at the center of the outer wall at the bottom of the turntable, and the outer wall of the output column is fixedly connected to the first gear, the outer wall of the first gear is meshed with the second gear, the inner wall of the second gear is fixedly connected to the input column, the bottom of the outer wall of the input column is installed with a first bevel gear, the outer wall of the first bevel gear is meshed with the second bevel gear, and a servo motor is installed on the outer wall of one side of the second bevel gear.

[0011] Preferably, a meter counter is installed on the top outer wall of the input column, and the meter counter is installed on the top inner wall of the chassis.

[0012] Preferably, the top outer wall of the chassis is equipped with symmetrically distributed guide rollers.

[0013] Preferably, a fixing plate is welded to the outer wall of the top of the chassis, and a third screw is provided on the outer wall of the top of the fixing plate. One end of the outer wall of the third screw is rotatably connected to a positioning plate, and a baffle is welded to the inner wall of one side of the positioning plate.

[0014] Preferably, a guide rod is welded to the outer wall of one side of the positioning plate, and the guide rod is slidably connected to the inner wall of the fixing plate.

[0015] Preferably, a PLC controller is installed on the inner wall of the bottom of the chassis, and the PLC controller is connected to the servo motor and the meter through signal lines.

[0016] The beneficial effects of the utility model are:

[0017] 1. In this design of a steel structure bending machine, the center sleeve and the disc seat on the top of the rotating table are not fixedly connected. Instead, the first screw is screwed into the internal threaded sleeve, so that the anti-slip sheet is tightly attached to the top of the center sleeve to fix it. This reduces the difficulty of replacing the center sleeve and allows the center sleeves of different outer diameters to be replaced according to the inner diameter requirements of the steel structure when bending. This allows for flexible use and a wide range of applications.

[0018] 2. The steel structure bending machine designed in this paper is equipped with an anti-warping structure on one side of the traction column. According to the size of the steel structure, the second screw is rotated to drive the pressure plate to move up and down to adapt to the steel structure, so that the pressure plate and the pressure block just fit the top of the steel structure, ensuring the overall straightness of the steel structure during the bending process, thereby improving the qualification of the product.
