Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of bending devices, and more specifically, relates to a bending device for steel structures. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to its light weight and ease of construction, it is widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to corrosion; therefore, they generally require rust removal, galvanizing, or painting, and regular maintenance.
[0003] A bending device for steel structure construction, as described in patent application number CN202420235484.7, includes a base, a support bracket, a lifting component, and an arc-shaped slide rail. The top of the base is connected to the support bracket. The support bracket has a lifting groove. The side of the lifting component is slidably connected to the inner wall of the lifting groove. The lifting component has a fixing clamping structure for fixing and clamping the steel structure material. The side of the support bracket is connected to the arc-shaped slide rail. The side of the arc-shaped slide rail has a rotating clamping structure for rotating and clamping the steel structure material. This invention can effectively improve the accuracy of angle control during the bending process. It can achieve bending at any angle within a certain rotation angle range. At the same time, the lever structure can effectively amplify the motor torque of the device, thereby ensuring the bending stability of the device.

A pair of electric cylinders 22 are fixedly connected; the output ends of the pair of electric cylinders 22 are fixedly connected to electric cylinder 23; the bracket 19 has a sliding groove 24; the output end of the electric cylinder 23 passes through the sliding groove 24 and is fixedly connected to the pressure roller 25; by setting the sliding groove 24, electric cylinder 23, and pressure roller 25, the pressure roller 25 always presses the bent part of the steel plate onto the bending block 11, improving processing efficiency and making it more practical; by setting the electric cylinder 28 and the extension plate 12, the extension plate 12 can extend forward to support the bent steel plate, adapting to the processing of steel plates of different lengths, making it more practical.
[0017] Please see Figure 1 The bending block 11 is slidably connected to the expansion plate 12 on its inner side; electric cylinders 18 are fixedly connected to both sides of the bending block 11; the output ends of the two electric cylinders 18 are fixedly connected to the expansion plate 12.
[0018] Please see Figure 1 The two sides of the operating table 10 are fixedly connected to support plates 15; each support plate 15 is provided with a sliding groove 16; the two ends of the rotating shaft 17 slide inside the sliding groove 16 on both sides.
[0019] Please see Figure 1 The bending block 11 is made of high-hardness stainless steel.
[0020] Please see Figure 1 The pressure roller 25 is made of high-hardness and high-toughness stainless steel. By setting up a support plate 15, a slide groove 16, and a rotating shaft 17, the support plate 15 supports the rotating shaft 17, which facilitates observation of the bending angle and can also provide auxiliary support for the bending block 11, thereby improving the stability of the processing and making it more practical.
[0021] During operation, the electric cylinder 14 is activated, and the output end of the electric cylinder 14 retracts, causing the bending block 11 to rotate relative to the operating table 10. Then, the bending block 11 folds relative to the upper surface of the operating table 10. After adjusting to a suitable angle, the steel plate is placed on the upper side of the operating table 10, and the bent part extends out of the operating table 10. Then, according to the folding angle of the bending block 11, the electric cylinders 22 and 23 are adjusted so that the pressure roller 25 always presses the steel plate on the bending block 11 to complete the bending.
[0022] When the bent section is long, the electric cylinder 18 is activated. The output end of the electric cylinder 18 drives the extension plate 12 to extend, which can further support the bent part of the steel plate and make it more practical.
