Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled steel coils, in particular to a hot-rolled steel coil rapid unfolding device. Background Art

[0002] Hot-rolled steel coils are widely used in the construction industry. Whether it's large commercial buildings, residential high-rises, or industrial plants, they all require large quantities of steel to construct their structural frames. Hot-rolled steel coils offer high strength and excellent plasticity, allowing them to be processed into a variety of building components, such as beams, columns, and channels. With the acceleration of urbanization, demand for hot-rolled steel coils in the construction industry continues to grow, creating a broad market for their production.

[0003] In the production process of hot-rolled steel coils, a series of subsequent processing steps are often required, such as cutting, flattening, and stamping. To ensure the smooth progress of these processes, the steel coils must first be unrolled from coils into sheets. Hot-rolled steel coil unrolling devices were developed to meet this need for bridging production and processing.

[0004] However, most traditional steel coil unwinding devices place the steel coil on the device and rely on a conveyor to open it. However, the tension conditions of the inner and outer layers during unwinding are different. The outer layer is farther away from the center of the circle and is more susceptible to greater tension during unwinding, while the inner layer has relatively less tension, which may lead to surface quality problems of the steel coil due to uneven tension. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a rapid unfolding device for hot-rolled steel coils, which aims to improve the problem that the inner and outer layers are subjected to different tensions when unfolding. Since the outer layer is farther away from the center of the circle, it is more susceptible to greater tension when unfolding, while the inner layer has relatively smaller tension, which may lead to surface quality problems of the steel coils due to uneven tension.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a device for quickly unfolding hot-rolled steel coils, comprising a load-bearing plate, the lower surface of the load-bearing plate is fixedly connected to a connecting plate, the outer wall of the connecting plate is fixedly connected to a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected to a cross bar, the lower surface of the cross bar is fixedly connected to a slide plate, the outer wall of the connecting plate is fixedly connected to a limiting rod, the inner part of the cross bar is slidably connected to the outer wall of the limiting rod, the inner part of the load-bearing plate is fixedly connected to a first rotating column, the outer wall of the first rotating column is rotatably connected to the first connecting rod, the outer wall of the first connecting rod is rotatably connected to the second connecting rod, the inner part of the second connecting rod is rotatably connected to the outer wall of the cross bar, the outer wall of the slide plate is fixedly connected to a baffle, the outer wall of the baffle is fixedly connected to the fixed column, and the outer wall of the load-bearing plate is provided with a conveying assembly, which is used to convey the steel plate.

[0007] Preferably, the conveying assembly includes a workbench, the outer wall of the workbench is slidably connected to the outer wall of the load-bearing plate, the outer wall of the workbench is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to a connecting column.

[0008] Preferably, the interior of the load-bearing plate is rotatably connected to a bearing, and the outer wall of the bearing is fixedly connected to a rolling column.

[0009] Preferably, the lower surface of the load-bearing plate is fixedly connected to a sliding rod, and the lower surface of the sliding rod is fixedly connected to an H-shaped bracket.

[0010] Preferably, the outer wall of the sliding rod is slidably connected to a frame, and the lower surface of the frame is fixedly connected to a bottom plate.

[0011] Preferably, a second motor is fixedly connected to the upper surface of the base plate, and a worm is fixedly connected to the output end of the second motor.

[0012] Preferably, the outer wall of the worm is meshedly connected with a worm wheel, and the interior of the worm wheel is fixedly connected with a second rotating column.

[0013] Preferably, the outer wall of the second rotating column is rotatably connected to a fixed bracket, the outer wall of the fixed bracket is fixedly connected to the outer wall of the frame, both ends of the second rotating column are fixedly connected to a third connecting rod, and the inner wall of the third connecting rod is rotatably connected to the outer wall of the H-shaped bracket.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the present invention, the hydraulic cylinder is started to push the cross bar to move, thereby driving the slide to move. When the slide moves, it drives the second connecting rod to rotate, thereby driving the first connecting rod to rotate, ensuring that the force applied to the cross bar is uniform when it moves. The movement of the cross bar drives the movement of the baffle, and the movement of the baffle drives the movement of the fixed column, thereby clamping and fixing the steel coil, thereby achieving the effect of reducing the surface quality problems of the steel coil caused by uneven tension.

[0016] 2. In the present invention, the second motor is started to drive the worm to rotate, thereby driving the worm wheel to rotate. The rotation of the worm wheel drives the second rotating column to rotate, thereby driving the third connecting rods on both sides to rotate, thereby pushing the H-shaped bracket to move. The movement of the H-shaped bracket drives the sliding rod to move, so that the position of the steel plate entering the middle of the two connecting columns can be adjusted according to the change in the volume of the steel coil, so that the steel plate is always in a horizontal state during transmission, thereby preventing the steel plate from deformation.
