Novel connecting shaft bracket for short-stress rolling mill

Abstract

The invention discloses a novel connecting shaft bracket for a short-stress rolling mill. The novel connecting shaft bracket comprises a rolling mill bracket, elastic connecting pieces which are installed on the two sides of the rolling mill bracket and are symmetrically arranged, a plurality of connecting rods which are installed in the rolling mill bracket, a screwdown device which is installedat the top of the rolling mill bracket and is connected and fixed to the connecting rods through bolts, and an encoder which is installed at the top of the rolling mill bracket and is positioned on one side of the screwdown device. After the novel connecting shaft bracket is applied to the short-stress rolling mill, the bracket can be matched with the short-stress rolling mill for automatic control and synchronously adjusted with the running state of the short-stress rolling mill, so that the opening degree of the short-stress rolling mill is conveniently adjusted, and process equipment accidents and product quality accidents caused by out-of-tolerance bounce values during running of the short-stress rolling mill are reduced, so that, the hourly yield and the product yield are improved.

Description

technical field [0001] In particular, the invention relates to a new type of shaft bracket for short stress rolling mills. Background technique [0002] Rolling mill bounce is an important indicator to reflect the performance of the rolling mill. In the production of hot-rolled bars, the size of the mill bounce value directly affects the production stability and product quality, especially the number of finished products. When the bounce value exceeds a certain range, it will directly cause size waste. Usually The scope of use of rolling mill bounce value is: rough and middle rolling group ≤ 0.6mm, finishing rolling group ≤ 0.4mm, splitting and finished rolling mill ≤ 0.2mm. [0003] With the prolongation of the online service time of the short-stress rolling mill, the gap between the main and auxiliary nuts due to wear and the gap between the copper nut and the spherical pad of the bearing seat due to the decrease in the fatigue resistance of the butterfly spring and the la...

Problems solved by technology

At present, because the shaft connecting bracket of the short-stress rolling mill is adjusted by sprocket, the specific use method is through manual adjustment, which cannot cooperate with the automatic control of the short-stress rolling mill, nor can it be adjusted synchronously with the operating state of the short-stress rolling mill. It is difficult to adjust the opening of the short-stress rolling mill, resulting in process equipment accidents and product quality accidents caused by the jump value of the short-stress rolling mill, thereby reducing the hourly output and product yield
