Abstract
The utility model discloses a seamless steel tube disc guiding device used in the process of rolling a seamless steel tube by a tube rolling mill, comprising a disc guiding ring, a disc guiding hub and a disc guiding body, wherein the shape of the outer edge surface of the disc guiding ring is a hole type of a steel rolling tube; the disc guiding ring is connected with the disc guiding body by bolts which are evenly distributed; and the disc guiding body is connected with the disc guiding hub by the bolts which are evenly distributed. The disc guiding ring is made of high wear-resistant alloy material, so that the wear-resisting property and the anti-impact property of the disc guiding ring can be improved. After steel tube rolling is carried out for a long time, the disc guiding ring can be conveniently replaced, and the whole disc guiding device is not needed to be changed, so that the production cost of the seamless steel tube is reduced.
Description
Technical field
The utility model relates to a kind of pipe mill used godet device in the rolling seamless steel pipe process, belongs to the roll seamless steel tube technical field.
Background technology
Godet is one of tool and mould form of roll seamless steel tube equipment, and the quality of godet product quality is most important to the production effect of steel pipe, directly influences the output and the quality of steel pipe rolling.Godet mainly plays aligning, guide effect in the steel pipe rolling process, invar pipe operation of rolling operating mode complexity is very high to material wear-resistant, the shock resistance requirement of godet.Along with the continuous development of roll seamless steel tube technology, godet replaces guide plate, and it is development trend that little godet changes big godet into.At present, the manufacturing of big godet has two classes, and a class is monoblock cast, though can realize the variation of material, is difficult to guarantee the high alloy and the high-performance of outer loop material, and the disposable use of interior loop material, and waste is serious; Another kind of is that Internal and external cycle adopts the forging mode, its dense structure, but the kind of outer loop material is few, forging will be used hydraulic press, and amount of machining is big, and the anti-wear performance of outer ring is poor, the life-span short, the concentricity difference and the interchangeability of the connecting hole between the Internal and external cycle are poor, and the shock resistance of Internal and external cycle is poor, breaks easily, and above defective causes that the steel pipe rolling energy resource consumption is big, efficient is on the low side, the high deficiency of cost.
The utility model content
The utility model purpose is to provide a kind of godet device of new structure, adopt guide coil, godet hub and godet body three-decker, guide coil adopts the alloy material manufacturing of high abrasion, improve the anti-wear performance and the shock resistance of guide coil, adopt cotter bolt to connect simultaneously between guide coil and the godet body, improve the interchangeability of guide coil, reach the logical requirement of changing of wildcard.
The technical solution of the utility model is achieved in that
Seamless steel pipe godet device, comprise guide coil, godet hub and godet body, be shaped as the pass of institute's steel rolling pipe at the outer fringe surface of described guide coil, it is characterized in that: adopt equally distributed bolt to connect between described guide coil and godet body, godet body and the godet hub.
The bolt that connects between described guide coil and the godet body is a cotter bolt.
The utility model compared with prior art has following advantage:
1. this godet device adopts guide coil, godet hub and godet body three-decker, and guide coil adopts the alloy material manufacturing of high abrasion, improves the anti-wear performance and the shock resistance of guide coil.Behind long-time rolled steel tube, can easily guide coil be changed, and need not change whole godet device, reduced the production cost of seamless steel pipe.
2. adopt cotter bolt to connect between guide coil and the godet body, improve the interchangeability of guide coil, guarantee the concentricity of guide coil and godet body, reach the logical requirement of changing of wildcard.Reduced the replacing time of guide coil.
