Professional Customized Precision Small Bushing Guide Sleeve Wear-Resistant Copper Sleeve

 

In the screwdown device of the roughing mill of the medium and heavy plate rolling mill and the hot rolled strip rolling line, the screwdown nut and screw are very important components. During the rolling process, every adjustment of the rolling gap is completed by the screwdown nut and screw, and the huge pressing force is also transmitted to the frame through them. If the screwdown nut and screw fail, it will cause the entire rolling line to stop production.
Pressing down the nut is one of the vulnerable parts on a steel rolling mill, except for the roller. The nuts are generally cast with high-strength bronze or high-strength brass. Therefore, it is necessary to adopt a reasonable structure to ensure that the screwdown device can work well. There are two types of screwdown nut structures: integral and combined.
Pressing down nuts is also applied to electric screw presses, which are forging equipment with strong process applicability. Its structure uses screws and copper nuts as transmission mechanisms, and relies on screw transmission to transform the forward and reverse rotation motion of the flywheel into the reciprocating motion of the slider. It is a forging machinery. During operation, the electric motor accelerates the flywheel rotation to store energy, while pushing the slider downward through screws and copper nuts.
