Description

Technical Field

[0001] The utility model relates to the technical field of safety pressing plates, in particular to a safety pressing plate for an outlet conduit of a high-speed wire rod rough and medium rolling mill. Background Technique

[0002] The Morgan V high-speed wire rod rolling mill is the main model currently used for high-speed wire rod production in China. Its main production process flow is billet loading, heating, rough rolling, medium rolling, pre-finishing rolling, finishing rolling, water cooling, wire laying, Stelmor air cooling line, coiling, P / F line, trimming, packing, weighing, uncoiling, and warehousing. The main function of its rough and medium rolling mill group is to perform large reduction on the raw material billet to provide qualified billets for pre-finishing rolling. Therefore, its rolling force is large, and the impact and wear of the rolled piece on the outlet guide guard clamping plate are relatively large, and it is necessary to ensure reliable connection and fastening between the outlet guide guard clamping plate and the guide guard box. However, if the fastening force between the outlet guide guard clamping plate and the guide guard box is too large, when the rolled piece impacts the outlet clamping plate due to an elbow or other reasons and the outlet clamping plate does not withdraw due to the rupture of the safety pressing plate, it will cause damage to the overall guide guard box, outlet rotating body, and guide guard support base, resulting in the expansion of the accident.

[0003] Therefore, it is necessary to design a safety pressing plate for the outlet guide guard of a high-speed wire rod rough and medium rolling mill. When the rolled piece impacts the outlet clamping plate due to an elbow or other reasons, the safety pressing plate will rupture due to excessive impact load, and the outlet clamping plate will withdraw due to the rupture of the safety pressing plate, reducing the impact damage of the rolled piece on the overall guide guard box, outlet rotating body, and guide guard support base, and reducing the accident loss and shortening the accident handling time.
