Description
Technical Field
The invention belongs to the technical field of metallurgical equipment, and particularly relates to a height fine adjustment device for a looping roller of a plate and strip rolling mill.
Background
The loop devices are arranged between the frames of the plate and strip finishing mill group (F1-F7), and the loop devices are mainly used for tensioning loop amount of rolled pieces appearing between the rolling mills, preventing the rolled pieces from being folded and entering the rolling mills to cause roll breakage or steel piling, ensuring smooth rolling production, and controlling the loop amount through the servo hydraulic cylinder. When thick products are rolled, all rolling mills are not required to be put into operation for rolling (at the moment, one rolling mill is required to be empty, the rolling mill has no rolling force), the loop is in a free flat state after the rolling mill is empty (in the state, the loop control hydraulic cylinder is stopped and is not subjected to servo control), the elevation of the loop roller is basically equal to the elevation of the guide and guard at the inlet of the rolling mill, and the guide and guard lining plate can scratch the strip steel.
In order to avoid the scratch of the guide lining plate on the strip steel, the method of adjusting the elevation of the looping roller is adopted to solve the problem, such as a cushion block method, a gasket method and the like, wherein a cushion block with proper height is directly connected to the position below a looping roller supporting arm and the like. The height of the loop roller is adjusted to be high by adopting a cushion block method and a gasket method, and the main defects are as follows: 1) time-consuming, labor-consuming, and unreliable: the adjusting cushion block and the gasket are easy to fall off, and the falling off is easy to occur due to the influence of factors such as the inclined plane of the supporting arm of the loop roller, vibration during production and the like; in addition, when all the rolling mill production is recovered, the adjusting cushion blocks and the gaskets need to be detached, and when the adjustment is needed, the installation and the alignment need to be carried out again; 2) the adjusting precision is not high, no matter the cushion block or the gasket, the size of each part is fixed, but because the factors such as corrosion, iron scale and the like exist at the installation position, the levelness error of the loop roller in the length direction of the roller body is larger.
Disclosure of Invention
The invention aims to provide a height fine-adjustment device for a looper roller of a plate and strip rolling mill, which is characterized in that when a plate and strip finishing mill set passes through one rolling mill in an idle mode, the required height of the looper roller after passing through the rolling mill is adjusted accurately and efficiently, namely, the fine adjustment of the looper roller on strip steel is realized, so that the elevation of the roller surface of the looper roller is slightly higher than that of a guide lining plate, and the guide lining plate is prevented from scratching the strip steel.
The technical scheme adopted by the invention for solving the technical problems is as follows: a height fine-adjustment device for a looping roller of a strip rolling mill comprises an adjusting bolt, an adjusting nut sleeved on the adjusting bolt, and a lining plate contacted with the adjusting bolt; adjusting nut is connected fixedly with the one end of connecting block, and on the other end of connecting block was fixed in pivot safety arm, the cover was equipped with fixation nut one and fixation nut two respectively on the adjusting bolt of adjusting nut both sides, and the welt passes through the bolt fastening on the connecting plate, and the connecting plate is connected fixedly with the buffer block support.
Specifically, adjusting nut and connecting block welded connection, connecting block and pivot safety arm welded connection.
Specifically, the connecting plate is connected with the buffer block support in a welding mode.
Specifically, two sets of loop roller height fine-adjustment devices are arranged and are respectively arranged on rotating shaft safety arms 9 on two sides of the loop roller.
The invention has the following beneficial effects: the invention adopts a screw mechanism consisting of bolts and nuts to realize the accurate fine adjustment of the height of the looper roll, and solves the problem that when a plate and strip finishing mill set passes through a rolling mill in production, the required height of the looper roll after passing through the rolling mill is accurately and efficiently adjusted, so that the elevation of the roll surface of the looper roll is slightly higher than that of the guide and guard lining plate, and the guide and guard lining plate is prevented from scratching strip steel. The invention has the advantages of simple design structure, convenient adjustment operation, high working efficiency, high adjustment precision, firm and safe use and the like, and can be used for a long time without disassembly after one-time installation, namely when the empty rolling mill and the subsequent looper roll are recovered to be normally used, the structure is not required to be disassembled, and only the adjustment bolt is finely adjusted backwards.
