Description

Technical Field

[0001] The utility model relates to the technical field of centering roller frames, in particular to a chuck type welding centering roller frame device. Background Art

[0002] Centering refers to the centering device in the piercing and rolling production of seamless steel pipes. Correct centering of the push rod is the primary process requirement. If the push rod is not centered accurately and the head deviates from the rolling center, it will cause uneven wall thickness of the rough pipe and aggravate the vibration of the piercing and rolling process. The huge rolling force will accelerate the wear of the equipment and increase the consumption of tools such as the push rod and the head. The greater harm is that the metal slip of the rough pipe during the piercing process will increase, which will reduce the piercing and rolling speed and affect the output. It will also cause production accidents such as the punching machine getting stuck. The chuck-type welded centering roller frame is a type of centering device, which is used to center the position of the seamless steel pipe.

[0003] The chuck-type welded centering roller stand can complete the centering operation of the seamless steel pipe during use. However, in actual use, since the outer side of the centering roller will be squeezed against the outer side of the seamless steel pipe, some debris will easily fall off the seamless steel pipe during the production process. These debris will adhere to the outer side of the centering roller, and then during the use of the centering roller, impurities will easily damage the seamless steel pipe, thereby reducing the yield of the seamless steel pipe. Therefore, a chuck-type welded centering roller stand device is proposed to solve the above problem. Utility Model Content
