Description

Technical Field

[0001] The invention relates to the technical field of roller grinding, and in particular to a roller end surface grinding device and a processing method. Background Art

[0002] In the field of steel, nonferrous metal rolling and machinery manufacturing, the roller is the core component of the rolling mill. The processing quality of the roller end face directly affects the precision quality of the roller. The burr or unevenness of the roller end face will affect the installation of the roller in the rolling mill, and will also cause the roller to shake during the rotation process, affecting the stability of the rolling mill operation process, resulting in uneven stress distribution during the rolling process, and then causing problems such as plate thickness deviation, and even shortening the service life of the roller and the rolling mill. Therefore, efficient and accurate grinding of the roller end face is a key link to ensure production efficiency and product quality.

[0003] At present, the traditional roller end face grinding technology mainly relies on the following methods: First, manual hand-held grinding, the operator uses tools such as disc grinders to manually grind the roller end face. This method is highly flexible, but has problems such as low efficiency, high labor intensity, poor consistency, and serious dust pollution, which endangers the health of workers. Second, fixed semi-automatic equipment, which fixes the roller with a simple clamp and grinds with a rotating grinding head or grinding belt. Although this type of equipment partially replaces manual labor and reduces the labor intensity of workers, its automation level is low, and loading and unloading and positioning still require manual intervention, which is difficult to meet the needs of continuous production.
