Abstract

The invention discloses a down-pressing nut replacement system which comprises an execution device and a control device, wherein the execution device is used for bearing and positioning a down-pressing nut when the down-pressing nut is replaced; and the control device is used for adjusting the up-and-down position of the execution device for bearing the down-pressing nut when the down-pressing nut is replaced. According to the down-pressing nut replacement system, through the cooperation of a guide rod and a guide sleeve, a bearing platform runs steadily; a throttling valve controls the running speed, so that the running speed can be adjusted in real time; the down-pressing nut replacement system is simple in structure and is operated safely and conveniently; reverse operation of the down-pressing nut is reduced; and the replacement time of the down-pressing nut is shortened from 2 to 3 days to 12 hours or so. The labor amount is reduced; and the stability, the safety and the accuracy of the down-pressing nut replacement process are fully guaranteed.

Description

technical field [0001] The invention relates to the field of special replacement tools for a hot-rolling production line, in particular to a screw nut replacement system. Background technique [0002] In the hot rolling production line, the reversing rolling mill depressing device is generally designed as two parts: mechanical depressing and hydraulic depressing, wherein the mechanical depressing includes depressing the lead screw and nut. The material of the pressing screw is 42CrMo, which is quenched and tempered, and the material of the pressing nut is Cu-based alloy. During use, the wear of the screw nut is faster than that of the lead screw. After 3-5 years of use, when the gap between the screw nut and the screw nut is large, it is generally necessary to replace the screw nut. In the process of replacing the screw nut, the traditional replacement method needs to dismantle the screw nut of the depressed screw as a whole, and transport it to the outside of the frame for...
