Mill scale collecting system of bar straightener

Abstract

The invention discloses a mill scale collecting system of a bar straighter. A speed reducing motor is connected with a winding drum through a coupler, and the winding drum rotates along with the speed reducing motor. Two ends of a steel wire rope are connected to two ends of a movable trolley respectively, and the steel wire rope is wound on the winding drum through a fixed pulley block and a tensioning mechanism. A scrap box is fastened on the movable trolley and moves on steel rails along with the movable trolley. By the mill scale collecting system, mill scales generated after bars are straightened can be automatically collected, and workers can be liberated from heavy work; the mill scales are cleaned timely and are prevented from falling into a lower cross beam, reliability of a roll-separating mechanism of a lower straightening roll is improved, equipment service life is prolonged, and equipment maintenance is reduced.

Description

technical field [0001] The invention belongs to the technical field of straightening machines, in particular to an oxide scale collection system of a bar straightening machine. Background technique [0002] In my country's round steel production line, the overall installation level of heating furnace and rolling mill still has a certain gap with the world's advanced level, and the straightness and ovality of the rolled bars have great defects. In this case, straightening The machine has become an indispensable auxiliary machine to adapt to my country's national conditions, and it has obvious effects in improving the straightness and ellipticity of bars. [0003] Nowadays, a layer of iron oxide scale will appear on the surface of the rough-rolled bar in my country after annealing. During the straightening process, the iron oxide scale attached to the surface of the bar will fall off in block or powder form to the equipment for straightening during the rolling process of the up...

AI Technical Summary

Problems solved by technology

As the amount of straightening increases, the iron scale needs to be cleaned in each shift. However, since there is not enough cleaning space at the straightening rollers, it is difficult to carry out the cleaning work and clean it up, which increases the cost of the straightening workers. Labor intensity

At the same time, with the vibration of the equipment, the iron oxide powder accumulated over time penetrates into the meshing part of the lower roll gap adjustment thread, which makes the adjustment screw and nut crushed, so that it is impossible to adjust the reverse bending of the straightener, which seriously affects the straightening of the equipment.
