Automatic polishing device for cold rolling roller surface waste

Abstract

The invention provides an automatic polishing device for cold rolling roller surface waste. The automatic polishing device is arranged on a rolling mill rack at the feeding side of a steel belt of a working roller, and comprises a polishing head, a pneumatic-driven polishing head telescoping mechanism, an axial driving mechanism and lead screw driving devices, wherein the polishing head performs telescopic movement through the polishing head telescoping mechanism, the polishing head telescoping mechanism is installed on the axial driving mechanism, and the axial driving mechanism adopts the lead screw nut driving mechanism, and is connected and driven through the lead screw driving devices to drive the polishing head telescopic mechanism to do reciprocating motion along the axis directionof the working roller. The polishing head capable of moving in a reciprocating mode is adopted, therefore, the angle of the polishing head can be adjusted along with the change of the roller diameterof the rolling roller, and the tail part of the polishing head is provided with a dust suction pipeline so that the waste polished by the polishing head can be sucked away by utilizing the negative pressure in time; and meanwhile, the contact pressure between the polishing head and the rolling roller can be adjusted, and the reciprocating motion distance and speed of the polishing head are also adjusted, so that the cleaning and polishing effects are improved.

Description

technical field [0001] The invention relates to a device for automatically polishing the garbage on the surface of a cold roll, belonging to the field of mechanical equipment. Background technique [0002] At present, sheet manufacturing mainly uses rolls for cold rolling; in order to ensure the surface roughness, surface quality, and thickness accuracy of the final sheet, it is necessary to ensure that the surface of the rolls, especially the work rolls, is kept clean, so it is often necessary to use oilstone, or some special Nylon polishing material for polishing the roller surface. [0003] At present, the equipment for online polishing of work rolls generally adopts a long fixed polisher, which cannot be moved but can only be stretched as a whole, and the length of the polishing head directly covers the entire width of the roll surface, and the extension angle of the polishing head cannot be adjusted. ;Due to the limitations of the existing polisher design, the thrown g...

AI Technical Summary

Problems solved by technology

However, after analysis, the polishing is an off-line polishing work after the roll is disassembled. It is mainly compared with a special grinder and polishing machine, which fails to meet the needs of online polishing. Although it has a certain reference for online cold roll polishing , but there is still a big gap from the actual production needs
