Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to a steel plate flattening device. Background Art

[0002] Before processing, steel coils often have uneven edges, curling, and warping. For flatness-required sheet metal processing, the uneven edges are usually cut off, resulting in material waste. To avoid this waste, the steel sheets need to be flattened.

[0018] Example 1

[0019] like Figure 1-Figure 2 As shown, a steel plate flattening device proposed in this embodiment includes two sets of flattening mechanisms and two sliding frame mechanisms that are symmetrically arranged in the upper and lower parts.

[0020] The flattening mechanism includes a mounting plate 2, two rotating seats 3 connected at both ends of the mounting plate 2, multiple flattening rollers 1 rotatably mounted between the two rotating seats 3, and a first power assembly for driving the multiple flattening rollers 1 to rotate synchronously. The first power assembly includes a reduction motor 4, multiple first gears 15 and multiple second gears 16. The reduction motor 4 is mounted on the rotating seat 3 and its output shaft is connected to the rotating shaft of the flattening roller 1. The multiple first gears 15 are respectively mounted on the rotating shafts of the multiple flattening rollers 1 arranged side by side. The multiple second gears 16 and the multiple first gears 15 are spaced apart from each other, and the adjacent two first gears 15 are meshed and connected with the second gear 16. The multiple flattening rollers 1 are arranged side by side.

[0021] The two sliding mechanisms are symmetrically arranged on both sides of the flattening mechanism. The sliding frame mechanism includes a telescopic plate assembly and two sliding plates 7. The telescopic plate assembly includes a lower support plate 51, an upper support plate 52 and a hydraulic cylinder 6. The upper support plate 52 is located above the lower support plate 51. The lower support plate 51 and the upper support plate 52 are respectively connected to the two sliding plates 7. The hydraulic cylinder 6 is installed on the lower support plate 51 to drive the upper support plate 52 to rise and fall. A plurality of first rollers 111 are installed at the bottom end of the lower support plate 51. The two sliding plates 7 are both connected to the telescopic plate assembly. Sliding holes running through both ends of the mounting plate 2 are opened. The ends of each sliding plate 7 are slidably installed in the two sliding holes on the upper and lower sides respectively. A second power assembly for driving the sliding plates 7 on both sides to move closer to or away from each other is installed on the mounting plate 2. The second power assembly includes a servo motor 8 and a bidirectional screw rod 9. The servo motor 8 is installed on the mounting plate 2. The bidirectional screw rod 9 is connected to the output shaft of the servo motor 8. A first sliding hole is opened on the mounting plate 2. Two connecting sliders 10 are slidingly provided on the inner side of the first sliding hole. The two connecting sliders 10 are respectively connected to the sliding plates 7 on both sides, and the two connecting sliders 10 are both threadedly connected to the bidirectional screw rod 9.

[0022] In this embodiment, in this technical solution, the hydraulic cylinder 6 is provided to adjust the height of the telescopic plate assembly, thereby realizing the height adjustment of the upper flattening mechanism, and then adjusting the gap between the two flattening rollers 1 at the upper and lower ends, which is convenient for flattening steel plates of different thicknesses. It has strong applicability. When flattening large steel plates, the two sets of telescopic plate assemblies can be driven away from each other by the provided second power assembly to facilitate the placement of large steel plates. Since the length of the flattening roller 1 is shorter than the width of the steel plate, the purpose of this setting is to save space for the equipment and to save costs. The steel plate is flattened multiple times, and the flattening position is different each time until the entire steel plate is evenly flattened.

The bottom of the sliding frame 13 is equipped with multiple second rollers 112. The multiple rollers 14 are arranged side by side, one end of the scissor-type lifting frame 12 is mounted on the bottom mounting plate 2, the scissor-type lifting frame 12 is horizontally arranged, and the multiple sliding frames 13 are all mounted side by side on the scissor-type lifting frame 12; In the scheme, multiple rollers 14 are provided to support longer steel plates to prevent deformation of the steel plates due to excessive length after discharge; the scissor-type part of the scissor-type lifting frame 12 is composed of multiple X-shaped frames, and the X-shaped frame includes two crossed rotating rods, which are rotatably connected in the middle part of the two rotating rods, and mounting shafts are provided at both ends of the rotating rods.
