Abstract
The utility model relates to a seamless steel tube rounding die, which comprises a tapered inner die and is characterized by further comprising an outer die sleeve matched with the outer edge of a steel tube. The steel tube is rounded by adopting the outer die sleeve which is matched with the outer edge of the steel tube and the tapered inner die which is matched and combined with a steel tube inner hole, so that high outer edge roundness of the steel tube can be ensured in the rounding process, the inner hole is prevented from being deformed, and the product percent of pass is high.
Description
Technical field
The utility model relates to a kind of seamless steel pipe full circle mould.
Background technology
Seamless steel pipe in process of production, it is after solution heat treatment, especially the steel pipe head was stressed gently promptly yielding after the light-wall pipe of ￠ 168 and above specification (￠ 168, ￠ 219, ￠ 273, ￠ 325) hung out from heat-treatment furnace, when steel pipe was transported to finishing room through pickling, the steel pipe head is ovalisation all.Therefore, finishing room must carry out full circle to steel pipe earlier usually.Traditional steel pipe full circle is the internal mold with a band tapering, and the endoporus by manually an end of internal mold band tapering being put into steel tube end part knocks internal mold gently with iron hammer then, enters steel tube inner hole fully up to internal mold and makes its Internal Hole Deformation Cheng Yuan.Owing to only use the internal mold full circle, the steel pipe outer rim is typing not, so steel pipe has only endoporus stressed, sometimes also can be big the endoporus support, and both be difficult to guarantee the size of endoporus, also be difficult to guarantee the circularity of outer rim.Therefore, often outer rim circularity is poor for the steel pipe behind the full circle, and interior hole dimension is undesirable, causes the defect rate height.
The utility model content
The purpose of this utility model is to provide a kind of steel pipe that can guarantee in the full circle process, and its outer rim circularity is good, the indeformable seamless steel pipe full circle of endoporus mould.
Its technical scheme is: a kind of seamless steel pipe full circle mould, comprise the internal mold of being with tapering, and it is characterized in that: also have outer die casing with steel pipe outer rim coupling fit.
Its beneficial effect is: owing to adopt with the outer die casing of steel pipe outer rim coupling fit with internal mold that steel tube inner hole mates the band tapering that combines steel pipe is carried out full circle, so can guarantee that steel pipe is in the full circle process, its outer rim circularity is good, and endoporus is indeformable, the product percent of pass height.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of seamless steel pipe full circle mould comprises the internal mold 4 of being with tapering, also has the outer die casing 3 with steel pipe outer rim coupling fit.The profile of outer die casing is circular or square.
During the seamless steel pipe full circle, earlier steel pipe 2 is placed in parallel in the adapter sleeve 1 that is fixed on the support 6, then, outer die casing 3 correspondences are linked on the external diameter of steel tube head, the internal mold 4 that drives tapering with hydraulic transmission 5 moves horizontally to the termination of steel pipe portion again, enter the endoporus of steel pipe fully up to internal mold, promptly can't see till the gap between the endoporus of internal mold and steel pipe.Steel pipe outer rim circularity behind the full circle is good, endoporus is indeformable.
Claims (2)
1. a seamless steel pipe full circle mould comprises the internal mold of being with tapering, it is characterized in that: also have the outer die casing (3) with steel pipe outer rim coupling fit.
2. seamless steel pipe full circle mould according to claim 1 is characterized in that: described outer die casing (3) profile is for circular or square.
