Description

Technical Field

[0001] The utility model relates to the field of continuous casting machines, in particular to a straightening mechanism for continuous casting machines. Background Art

[0002] A continuous casting machine is a device used for continuously casting metals, usually used to produce metal billets, such as steel billets or aluminum billets. It is one of the key equipment in the modern metallurgical industry, with the advantages of high efficiency, energy saving, and high quality. It is widely used in the production of metal materials such as steel and aluminum alloys. One of the main components of a continuous casting machine is a casting device, which consists of a crystallizer and a crystal shell. The molten metal is transported from the smelting furnace to the pouring system of the continuous casting machine. When the molten metal enters the crystallizer, it begins to gradually cool and solidify. When the crystal shell is thick enough, the continuous casting machine begins to gradually stretch the crystal shell through a drawing mechanism to make it longer and continue to solidify during the crystallization process. When the continuous casting billet reaches the required length, it is cut into corresponding billet lengths and cooled to room temperature by a cooling device.

[0003] After searching, the Chinese patent announcement number CN212822566U is found, which discloses a straightening mechanism for a continuous casting machine. The patent sets an adjusting clamp on the guide roller of the straightening mechanism. According to the width of the cast plate, by turning the handle, the forward threaded rod and the reverse threaded rod are driven to rotate synchronously, so that the two groups of threaded barrels on the adjusting rod move synchronously inward or outward, thereby driving the interlaced connecting rod to move synchronously with the corresponding threaded barrel through the vertical rod and the longitudinal sleeve, and the adjusting clamp moves synchronously with the interlaced connecting rod, and adjusts the position of the adjusting clamp on the upper guide roller and the lower guide roller so that the inner end of the adjusting clamp is always engaged with the two sides of the cast plate, so that the cast plate is always in the middle position of the straightening mechanism under the push of the upper guide roller and the lower guide roller, preventing the cast plate from deviating forward and backward and contacting the vertical plug plate or the vertical plate, affecting the straightening effect of the cast plate.

[0004] Some impurities may adhere to the surface of the casting during the movement. If they are not cleaned in time before straightening, these impurities may be pressed into the casting during straightening, affecting the quality of the casting. Utility Model Content

[0026] A cleaning mechanism is provided on one side of the straightening mechanism 2, and the cleaning mechanism includes a stepper motor 301. A groove is provided on the top of the base 1, and the stepper motor 301 is bolted in the groove. The output end of the stepper motor 301 is connected to a mounting shaft 302 through a coupling. The mounting shaft 302 is located behind the casting, so as to facilitate sweeping impurities from the surface of the casting to avoid the cleaned impurities remaining on the surface of the casting. A first mounting block 303 and a second mounting block 304 are fixedly connected to the mounting shaft 302. The first mounting block 303 and the second mounting block 304 are aligned with each other with respect to the upper and lower sides of the casting. It is said that the outer walls of the first mounting block 303 and the second mounting block 304 are fixedly connected with a plurality of circumferentially arranged support frames 305, the support frames 305 are L-shaped, and a rotating shaft 306 is rotatably connected between the support frame 305 and the corresponding first mounting block 303 or the second mounting block 304, and a cleaning roller 307 tightly attached to the casting is fixedly connected to the rotating shaft 306, and a plurality of cleaning brushes are fixedly connected to the outer wall of the cleaning roller 307, and the cleaning brushes are made of heat-resistant material to prevent the cleaning brushes from being damaged by the high temperature on the surface of the casting, and a collection box 5 is bolted to the top of the base 1.
