Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel processing and production, and particularly relates to an online straightening and guiding device for stainless steel red blanks on a hot delivery roller. Background Art

[0002] In the production of stainless steel, the billet must first be heated and then hot rolled through a continuous casting machine; during this period, the billet and stainless steel must be guided and straightened to avoid transmission deviation that may cause the rolled stainless steel to have uneven widths and substandard quality.

[0003] Among them, billet transmission is the front end of the stainless steel rolling process, and this process is particularly important as the starting point of the process;

[0004] Regarding the transmission of steel billets, after searching, it was found that the prior art announcement number is CN 217889063 U, which is a clamping and straightening device for a wide-band thin-plate stainless steel hot-rolling flat-rolling line. The utility model is provided with a guide mechanism. When the stainless steel plate enters the guide mechanism after transmission, the guide plate is buffered and corrected in direction by the elastic force of spring Ⅰ; the distance between the push plates is adjusted to adapt to the width of the stainless steel plate by rotating the screw rod Ⅰ; in actual application, it is found that when the guide plate receives the deflected steel billet and straightens it, it is easy to be hit by the transmitted steel billet, resulting in pits or a large amount of oxide scale adhered. At the same time, the guide plate is set as a flat plate, and the above factors will increase friction, which is not conducive to the rapid straightening of the transmission of the steel billet;

[0005] To solve the above problems, after searching, an adjustable steel-out roller guide device with a prior art announcement number of CN 219541346 U was found. The adjustable steel-out roller guide device of the utility model is suitable for guiding steel billets on steel-out rollers for high-speed wire production. The guide device is divided into three parts, namely, a front guide plate, a roller wheel and a rear guide plate. The roller wheel is rotatably arranged between the front guide plate and the rear guide plate. Therefore, the opening degree of the guide roller can be adjusted in time according to the requirements of rolling steel billets of different specifications, and the guiding adjustment function of steel billets of different sizes can be met to prevent the steel billets from running off during operation and affecting the biting of the rolling mill. At the same time, a roller-type guide device is adopted, and a rolling friction method is adopted to replace the sliding friction method of the existing guide plate to achieve guidance. The problem of scratches on the surface of the steel billet is solved. Although this solution uses rollers for guidance instead of the sliding friction of the guide plate, which reduces friction and is beneficial to transmission, a large amount of oxide scale will still adhere to the roller during the rolling guidance process. Secondly, if the guide position is not correct, the steel billet will still collide with the roller, which will cause the shafts at both ends of the roller to bend, affecting the rotation of the roller, and further affecting the guiding effect of the roller.

[0006] Therefore, in view of the above problems, the present invention provides an online straightening and guiding device for stainless steel red billet. Summary of the invention

[0040] An online straightening and guiding device for stainless steel red billet on a hot delivery roller, the working process is as follows:

[0041] When the steel billet 4 is transmitted on the frame 1, it is first transmitted by the obliquely arranged second roller 12, so that the steel billet 4 with an incorrect direction will automatically converge to the middle of the frame during the transmission process, and then the guide mechanism 3 is used to adjust the guide to straighten the steel billet 4 into place again; in this process, the second oil cylinder 311 is first used to control the fixed plate 32 to move close to the steel billet 4, and then the steel billet 4 will touch the fourth roller 36 during the transmission. Compared with the contact of the flat plate, the fourth roller 36 changes from sliding to rolling, which reduces the friction; during this period, the spring 332 exerts pressure on the mounting plate 33 Shock absorption is achieved when the steel billet 4 hits the top; long-term guided straightening will cause the fourth roller 36 to deform and adhere to a large amount of oxide scale, affecting its own rotation; at this time, the second motor 351 in the control mechanism 35 can be used to mobilize the screw 353 to rotate, thereby driving the scraper 38 to slide down and scrape off the adhered oxide scale on the fourth roller 36; and then the first motor 341 in the adjustment mechanism 34 drives the first connecting rod 342 and the second connecting rod 343 to make the rack intermittently mesh with the gear at the end of the fourth roller 36 and rotate to adjust the angle to complete the comprehensive scraping of the oxide scale.

[0042] The threaded rod 37 can also be used to control the adjustment seat 334 to slide and release the lock on both ends of the fourth roller 36, so that the fourth roller 36 can be replaced.

[0043] Furthermore, the first oil cylinder 23 controls the mounting frame 22 to rotate around the pin shaft 221, so that the third roller 24 presses the steel billet 4. Compared with the conventional mode, the third roller 24 is provided with a protrusion 241 which can limit the steel billet 4 and effectively avoid the occurrence of the steel billet 4 sliding to both sides again during the subsequent transmission process. The above technical solution can effectively straighten and guide the steel billet during transmission.
