Technical Field
[0001] The utility model belongs to the technical field of steel rolling, and in particular relates to a guide and guard adjustment and centering platform. Background Art
[0002] A guide guard refers to a device installed before and after the roll hole during the steel rolling process to help the rolled piece enter and exit the roll hole accurately and stably in a predetermined direction and state. Before installing the guide guard, the centering of the guide guard body must be ensured. If the centering of the guide guard body is not accurate enough, the rolled piece will wear the guide rollers of the guide guard, and even cause the angle at which the rolled piece enters the rolling mill to change. Therefore, before the guide guard goes online, the left and right guide rollers of the guide guard need to be adjusted to a symmetrical state along the center. It is difficult to align with the naked eye, so sample rods and adjustment tables are needed to assist.
[0003] For example, in a Chinese utility model with announcement number CN214919250U, entitled a guide guard centering adjustment device, the base frame includes a front bracket and a rear bracket, the base frame includes a base and two parallel side panels, the front bracket is arranged at one end of the side panel connected to the base, and the rear bracket is arranged at the end of the side panel away from the base; fixed blocks are arranged on the opposite inner sides of the side panels, the fixed blocks are provided with threaded holes penetrating the longitudinal end faces of the fixed blocks, and tightening screws are arranged in the threaded holes. Although the above-mentioned prior art provides symmetrical sleeves on the front bracket and the rear bracket, and the sample rod used for centering is inserted into the two sleeves to start debugging the guide guard, the sample rod is in a stationary state to center the guide guard, while the rolled piece passes through the guide guard during movement, which will cause the guide guard to deviate and affect the centering accuracy. Therefore, a guide guard adjustment and centering platform is now needed. Utility Model Content
