[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0020] Example 1
[0021] A centering device for cold-rolled strip production, such as Figure 1 and Figure 2As shown, it includes a mounting base 1, the left and right parts of the mounting base 1 are both slidably connected to a sliding base 2, the mounting base 1 is internally rotatably connected to a first screw rod 3, the left and right parts of the first screw rod 3 are threaded, the first screw rod 3 is threadedly connected to the sliding base 2, the sliding base 2 is threadedly connected to a second screw rod 5, the inner ends of the second screw rods 5 are rotatably connected to a sliding plate 4, the second screw rod 5 is provided with a power-assisting handle, and the sliding plate 4 is provided with a protective mechanism 6 for limiting and protecting the side parts of the strip.
[0022] like Figure 1 and Figure 3 As shown, the protective mechanism 6 includes a fixed seat 61, and the fixed seat 61 is installed on the inner side of the sliding plate 4 by bolts. The fixed seat 61 is slidably connected with a sliding frame 62 for limiting the side edge of the strip, and two springs 63 are connected between the sliding frame 62 and the adjacent fixed seat 61. The lower part of the sliding frame 62 is rotatably connected with a rotating plate 64 for preventing the side edge of the strip from tilting, and two torsion springs 65 are connected between the rotating plate 64 and the adjacent sliding frame 62.
[0023] It should be noted that in order to avoid positional deviation during the production of strip steel, the present device can be used to center the strip steel. First, the device is placed on the lower side of the strip steel. Then, the first screw rod 3 is rotated to adjust the position of the sliding seat 2 so that the spacing between the sliding seats 2 can match the width of the strip steel. Then, the second screw rod 5 is rotated to adjust the position of the sliding plate 4 so that the sliding frame 62 can move to the edge position on both sides of the strip steel. By relying on the cooperation between the sliding frame 62 and the spring 63, the side parts of the strip steel are limited and protected, so that the strip steel can stably move in a plane. At the same time, during the centering process, by relying on the cooperation between the rotating plate 64 and the torsion spring 65, the possible warping state is suppressed and limited, thereby improving the protection effect of the strip steel and avoiding damage to the strip steel.
[0024] Example 2
[0025] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a clamping mechanism 7, which includes a mounting frame 71. There are two mounting frames 71, which are respectively mounted on the inner sides of the corresponding sliding seats 2. Ribs are installed on the mounting frames 71, and a clamping roller 72 for clamping the strip is rotatably arranged at the lower part of the mounting frame 71.
[0026] It should be noted that, during the centering process, the middle part of the steel strip is clamped and limited by the clamping roller 72 to prevent the middle part of the steel strip from tilting during movement, which would cause friction on the side parts.
[0027] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
