Seamless steel tube positioning adjustment device

Abstract

The invention provides a seamless steel tube positioning adjustment device which comprises a second air cylinder. A second ejector rod penetrates a frame to be connected with an I-shaped base plate, one end of the bottom of the I-shaped base plate protrudes to be provided with symmetrical compression rods, the other end of the bottom of the I-shaped base plate is provided with symmetrical guide plates capable of being adjustably connected, a first guiding plate is provided with a third air cylinder, a third ejector rod penetrates the first guiding plate to be connected with a cross-shaped fixing plate, a compression rod is arranged in the horizontal direction of the cross-shaped fixing plate, the end of the compression rod is provided with a spherical protrusion, auxiliary fixing rods arearranged on the two symmetrical sides of the cross-shaped fixing plate and the compression rod, and arc-shaped chamfers are arranged on the two auxiliary fixing rods. According to the seamless steel tube positioning adjustment device, the side wall fixed clamping manner can better adapt to different diameter requirements, the seamless steel tube positioning adjustment device can also be used for secondary punching pipe materials, motion is stable in the blank penetrating and forward pushing process, linear motion is kept all the time, the straightness accuracy is higher, and deflection is notprone to occurrence.

Description

technical field [0001] The invention belongs to the field of seamless steel pipe production equipment, and in particular relates to a seamless steel pipe positioning adjustment device. Background technique [0002] In the production and processing of seamless steel pipes, piercing steel pipe blanks is an indispensable link in the processing process. In the process of piercing, sometimes a good piercing state cannot be completed at one time, and secondary processing is often required. In the secondary processing, the billet becomes a steel pipe with holes. In this case, the diameter of the steel pipe changes, and the inside becomes hollow. The existing billet pusher has a simple structure and can only realize the straightening of the cylindrical billet. The advancement, and the scope of adaptation is small, does not meet the actual production needs, there is an urgent need for a special equipment that can meet the actual needs. In view of this situation, the present inventio...
