Problems solved by technology

[0003] When the steel coil is being uncoiled, it is set on the uncoiler and pulled by an external force to realize the uncoiling. However, when the existing steel coil is uncoiled, it is easy to be dragged out at the last stage, which affects the normal operation of the entire uncoil.

Abstract

The invention discloses a pneumatic positioning mandrel device for uncoilers, which comprises a base, a guide cylinder, a rotary telescopic shaft, a driving mechanism and an uncoiling roller, wherein the guide cylinder is arranged on the base, the rotary telescopic shaft is arranged in the guide cylinder, the driving mechanism is arranged on the base and used for driving the rotary telescopic shaft to move in the guide cylinder, and the uncoiling roller is arranged on the rotary telescopic shaft. The pneumatic positioning mandrel device disclosed by the invention is simple in structure and easy to fabricate, and can guarantee the stability of steel coils in the process of uncoiling, especially can solve the problem that the last section is not dragged out to affect the normal production of steel pipes.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a pneumatic positioning mandrel device for an uncoiler when a steel coil used in steel pipe processing is uncoiled. Background technique [0002] Many large-diameter steel pipes are welded by steel plates. The steel plates are pulled out from the steel coils and then spirally rotated forward. The welding torch completes welding during the advancement of the steel plates to form the required large-diameter steel pipes. [0003] When the steel coil is uncoiled, it is set on the uncoiler and pulled by external force to realize uncoiling. However, when the existing steel coil is uncoiled, it is easy to be dragged out at the last stage, which affects the normal operation of the entire uncoil. Contents of the invention [0004] The purpose of the present invention is to provide a pneumatic positioning mandrel device for an uncoiler, which has a simple structure, is easy...
