Description

Technical Field

[0001] The present application relates to the technical field of steel pipe correction, and in particular to a bearing steel pipe head bending correction device. Background Art

[0002] Bearing steel tube is a steel tube made of bearing steel, which can be used as the blank of bearing sleeve. The bearing steel tube formed by cold rolling (or hot rolling) in the steel mill is transported to the machining plant. During the transportation, due to impact, bump, extrusion and other factors, the heads of some bearing steel tubes are deformed. Before machining, they need to be corrected.

[0003] At present, there is no special equipment for the correction of the head of the bearing steel tube. Manual knocking or jack-assisted jacking are commonly used. The manual knocking method is time-consuming and laborious, and the jack-assisted jacking can only be applied to bearing steel tubes with extra-large diameters. There is currently no good solution for the commonly used bearing steel tubes with a diameter of 10cm-20cm. Therefore, the utility model provides a bearing steel tube head bending correction device.
