External transition belt grinding device for end upsetting of steel pipe

Abstract

The invention discloses an external transition belt grinding device for end upsetting of a steel pipe, belonging to the field of drilling equipment. The external transition belt grinding device comprises a lifting rotation roll, a grinding device, an adjusting device, guiderails and a dust collection box, wherein the dust collection box is an open box body, the adjusting device is fixedly arranged on the side surface of the dust collection box, the lifting rotation roll which is isolated from the dust collection box is arranged on the other side of the dust collection box opposite to the adjusting device, the guiderails are arranged on the upper surfaces of another two side walls of the dust collection box and provided with the grinding device. In use, the external transition belt grinding device is fast in grinding speed, high in production efficiency, simple and effect in structure, convenient to operate, safe and reliable to use, stable to run, excellent in performance, convenient to maintain, suitable for large-batch production and grinding, and long in service life.

Description

technical field [0001] The invention relates to a grinding device, which belongs to the field of drilling equipment, in particular to a grinding device for an outer transition zone used for thickening steel pipe ends. Background technique [0002] The thickened outer transition zone of the pipe end of the drill pipe body is the key part of the pipe end thickening forming. The quality of the position of the outer transition zone is closely related to the quality of the drill pipe, so the position inspection of the outer transition zone is required after the pipe end is thickened and formed. Whether there are defects such as cracks, etc., due to the thickening of the pipe end forging and subsequent heat treatment, there is a layer of oxide skin on the pipe end (most of the oxide skin on the pipe body can be removed by descaling and heat straightening machine), in order to ensure the The pipe end (especially the transition of the outer tapered surface) is subjected to magnetic ...

AI Technical Summary

Problems solved by technology

At present, the devices used by various manufacturers for grinding the thickened outer transition zone of the steel pipe end are mainly hand-held angle grinders, belt grinders and grinders, which have low work efficiency, large dust, and potential safety hazards, and are not suitable for mass production and grinding.
