Description

Technical Field

[0001] The utility model relates to the technical field of side looper devices, in particular to a high-speed wire rod side looper inlet material guiding device. Background Art

[0002] High-speed wire is a kind of steel, mainly used to manufacture bolts, nuts, welding wire and other products. The production process of high-speed wire is billet preheating, rolling, cooling, sizing, surface treatment and packaging. The rolling stage is divided into initial rolling, finishing rolling, finishing and other processes. The equipment used in finishing rolling is divided into pre-finishing mill and finishing mill. During the rolling stage, the rolling tension between the frames is adjusted by changing the height of the loop, so as to optimize the product quality. The existing looper layout is horizontal layout, pneumatic looping, and the distance between the horizontal looper entrance guide roller and the looping roller is small. When the loop is lifted, the horizontal looper guide roller is subjected to large force, the steel temperature is high, there is no cooling water, and the bearing dry oil lubrication effect is poor, resulting in excessive vibration wear gap of the base, and the deviation of the rolled piece causes serious wear on the front guide tube of the looper.

[0003] To solve the above problems, Patent Publication No.: CN206716737U provides a high-speed wire horizontal loop inlet guide control device, including a prefabricated plate, a water nozzle, an oil nozzle, a horizontal guide roller, a guide roller pressure bearing, a guide roller shaft, a guide roller shaft hole and a cooling water hole. By adjusting the horizontal guide roller spacing, the force between the horizontal guide roller and the looping roller is reduced, the horizontal guide roller is cooled by the water nozzle and multiple cooling water holes, and the guide roller pressure bearing is lubricated by the oil nozzle, thereby increasing the wear resistance of the guide roller and increasing the service life by 25 times.

[0004] The above patent increases the wear resistance of the guide rollers and cools the horizontal guide rollers during use, but there is still wear of the steel at the inlet duct, which easily produces steel piling, resulting in a decrease in the rolling line operation rate and yield rate. Utility Model Content

[0005] The utility model aims to provide a high-speed wire side loop inlet material guiding device to solve the problem of steel abrasion at the inlet guide tube and easy generation of steel pile in the existing patents.

[0007] The principle and beneficial effect of the utility model are as follows: the steel coming out of the pre-finishing mill enters the guide groove through the guide wheel on the support arm, passes through the gap between the upper and lower guide wheels to enter the guide groove, and then passes through the guide groove to enter the finishing mill, and the sliding friction between the steel and the guide groove entrance is changed to rolling friction, thereby reducing the wear of the steel and the loop entrance. When the guide groove produces slag due to long-term use and the wear of the steel, the limit assembly can be separated so that the cover plate can be rotated to open the guide groove, thereby cleaning the slag.

[0008] Option 2 is the preferred option of the basic option. A wear-resistant plate is provided on the inner wall of the guide groove. The wear-resistant plate is lower than the distance between the two guide wheels, which can effectively extend the life of the equipment and reduce costs.

[0009] Option three is the preferred option of the basic option. The limiting assembly includes a pin shaft. The free end of the cover plate and the guide groove are respectively fixed with a pin shaft ring. The pin shaft and the pin shaft ring are connected through and through, which is convenient for cleaning accumulated slag and extending the life of the equipment.

[0010] Option 4 is the preferred option of the basic option. An oil pipe is connected through each support arm, and the end of the oil pipe is located above the two guide wheels to facilitate oiling and lubricating the guide wheels.

[0011] Option 5 is the preferred option of the basic option. A cooling water pipe is connected through the support arm, and the end of the cooling water pipe is located in front of one side of the two guide wheels to facilitate cooling of the steel and the guide wheels.

[0012] Option six is ​​the preferred option of option five. An atomizing nozzle is fixedly connected to the cooling water pipe to facilitate the cooling water to be sprayed out in a mist form, thereby increasing the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS
