DETAILED DESCRIPTION
[0026] The following is combined with Figure 1-3 This application is described in further detail.
[0027] The embodiment of the present application discloses a cold-rolled strip leveling device.
[0028] refer to Figure 1 and Figure 2 The cold-rolled strip leveling equipment includes an equipment body 1, a mounting frame 2, a pressure plate 3 and a scraper 321. The equipment body 1 is provided with a plurality of bottom rollers, which drive the strip to move, and is provided with pressure rollers for flattening the strip. The mounting frame 2 is installed on the equipment body 1, and the middle position is for the strip to pass through. There are two pressure plates 3, which are installed on the inner top and inner bottom of the mounting frame 2, and the scraper 321 is installed on the opposite outer walls of the two pressure plates 3. The scraper 321 is inclined from the middle position to the direction of movement of the strip. The scraper 321 is made of rubber in this embodiment. An adjustment component 4 is provided between the mounting frame 2 and the pressure plate 3 to drive the pressure plate 3 to move in the vertical direction.
[0029] The two pressure plates 3 are driven closer to each other by adjusting the component 4, so that the scraper 321 can be pressed against the upper and lower surfaces of the strip, and then the foreign matter on the surface of the strip is scraped off by the scraper 321 during the movement of the strip, thereby effectively improving the cleanliness of the strip surface, and then reducing the probability of the strip being pressed into grooves or scratches by foreign matter during the subsequent roller leveling process, thereby improving the product quality and the service life of the equipment.
[0030] refer to Figure 3 The adjustment assembly 4 includes an adjustment screw 41, an adjustment block 42 and a rotating rod 43. The adjustment screw 41 is rotatably connected to the top and bottom of the inner wall of the installation frame 2 and is arranged horizontally. One end of the adjustment screw 41 passes through the installation frame 2 and then extends out and is provided with a handle. The part of the adjustment screw 41 in the installation frame 2 has opposite threads distributed from the middle position to both sides. There are two adjustment blocks 42 on one adjustment screw 41, and the threaded part different from the adjustment screw 41 is threadedly connected, and the adjustment block 42 abuts against the inner wall of the installation frame 2. The rotating rod 43 is rotatably connected to the adjustment block 42, and the other end is rotatably connected to the pressure plate 3. The inner wall of the installation frame 2 is provided with a stable groove 22 for the two ends of the pressure plate 3 to abut and slide.
[0031] The pressing plate 3 includes an outer frame 31 and an inner plate 32. The rotating rod 43 is rotatably connected to the outer frame 31, the scraper 321 is fixedly connected to the inner plate 32, and the inner plate 32 is slidably connected to the outer frame 31. An intercepting plate 325 arranged to be tilted downward is fixedly provided at the edge of the inner plate 32 of the scraper 321 below the strip. The outer wall of the inner plate 32 away from the scraper 321 is a first clamping plate 322. The first clamping plate 322 is pressed against a sponge strip 323 in the outer frame 31. A second clamping plate 324 is fixedly provided on the other side of the sponge strip 323. The sponge strip 323 is in a pressed state in the outer frame 31. Slide-out holes 21 are provided at the top and bottom of the side wall of the mounting frame 2. The slide-out holes 21 allow the inner plate 32, the second clamping plate 324, the sponge strip 323, the first clamping plate 322 and the scraper 321 to extend out together.
[0032] The adjusting screw 41 is rotated to drive the two adjusting blocks 42 to approach each other, and then the outer frame 31 is driven downward by the rotating rod 43, and the inner plate 32 is pushed toward the strip, so that the scraper 321 is pressed against the strip. In this process, the inner plate 32 will press the sponge strip 323 through the first clamping plate 322, and then the scraper 321 is always pressed against the strip stably by the pressing force of the sponge strip 323. In the process of the strip passing, the scraper 321 intercepts foreign matter on the surface of the strip, and drains the foreign matter to both sides by tilting the surface, which effectively improves the surface cleanliness of the strip before leveling, thereby reducing the probability of foreign matter being pressed on the strip by the pressure roller, and improving the quality of the strip and the service life of the equipment. When the scraper 321 needs to be replaced, the adjusting screw 41 is rotated to drive the outer frame 31 upward, so that the slide-out hole 21 is opposite to the outer frame 31, and then the inner plate 32 slides out of the slide-out hole 21, and then the scraper 321 is replaced.
[0033] The implementation principle of the cold-rolled steel strip leveling equipment of the embodiment of the present application is as follows: after the steel strip passes through the installation frame 2, the adjusting screw 41 is rotated so that the scraper 321 is pressed against the surface of the steel strip, and then during the movement of the steel strip, the scraper 321 cleans the foreign matter on the surface of the steel strip, thereby reducing the residual foreign matter on the surface of the steel strip, thereby reducing the probability of foreign matter being pressed on the steel strip during the leveling process, improving the quality of the steel strip leveling, and increasing the service life of the equipment. At the same time, the sponge strip 323 can always keep the scraper 321 pressed against the surface of the steel strip with appropriate force through elastic force, thereby improving the stability of scraping foreign matter on the surface of the steel strip.
[0034] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
