Abstract
The utility model discloses a seamless steel pipe rounding mechanism, which comprises a holder and a conical inner mold, wherein a steel pipe is arranged on the holder, one end of the holder is provided with an inner mold guide sleeve, an outer mold fixing sleeve which is matched with the outer edge of the steel pipe is arranged outside the steel pipe, and the outer mold fixing sleeve is a square fixing sleeve. Due to adopting the seamless steel pipe rounding mechanism, the defects of the prior art can be overcome, simpliness in design and reasonability in structure can be realized, the roundness of the outer edge in the rounding process of the steel pipe is good, the size is stable, and convenience in use in the rounding process can be realized.
Description
Technical field
The utility model relates to the cold-drawn technical field of steel pipe, specifically belongs to a kind of seamless steel pipe full circle mechanism.
Background technology
Seamless steel pipe is adding man-hour, and it is through after the solution heat treatment, and the steel pipe head was stressed gently after especially thinner steel pipe hung out from heat-treatment furnace very easily is out of shape, and when steel pipe was transported to finishing room through pickling, the steel pipe head is ovalisation all.Therefore, finishing room needs first steel pipe to be carried out the full circle processing usually.Traditional steel pipe full circle is that the internal mold with a tapering passes in the steel pipe by manually internal mold being knocked, and with its reparation, its endoporus can be repaired, but its outer hole dimension is difficult to guarantee easily distortion when knocking.
The utility model content
The purpose of this utility model provides a kind of seamless steel pipe full circle mechanism, has overcome the deficiencies in the prior art, and simplicity of design is rational in infrastructure, and in the process of repairing the steel pipe full circle, outer rim circularity is good, and dimensionally stable is easy to use in the full circle process.
The technical solution adopted in the utility model is as follows:
A kind of seamless steel pipe full circle mechanism comprises the internal mold of fixed mount and taper, and steel pipe is positioned on the fixed mount, and described fixed mount one end is provided with the internal mold fairlead, and steel pipe is provided with the external mold fixed cover with steel pipe outer rim coupling fit outward, and the external mold fixed cover is square fixed cover.
Described taper internal mold is connected on the power set by screw rod.
Described screw rod passes the taper internal mold and fixes.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The outer fixed cover that cooperates in the steel pipe outer rim is adopted in the utility model design, is combined with the taper internal mold, and steel pipe is carried out full circle, can guarantee steel pipe in the full circle process, and outer rim circularity is good, and endoporus is indeformable, improves product quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of seamless steel pipe full circle mechanism comprises the internal mold 2 of fixed mount 1 and taper, steel pipe 3 is positioned on the fixed mount 1, fixed mount 1 one ends are provided with internal mold fairlead 4, the steel pipe 3 outer external mold fixed covers 5 that mate fit with the steel pipe outer rim that are provided with, and external mold fixed cover 5 is square fixed cover.Taper internal mold 2 is connected on the power set 7 by screw rod 6, and it is fixing that screw rod 6 passes taper internal mold 2.
