Abstract
The utility model relates to a novel four-roller guiding device. Four groups of roller posts are uniformly arranged on a roller way base; roller surfaces of the four rollers are tangential to a needed guiding cylinder to form a closed loop; and surface of a steel tube rotates together with the four groups of roller posts in a rolling process, so that swinging coefficient of the steel tube is limited, great swinging of a pierced billet during rolling is reduced, thereby screw thread quality of products is improved to a certain degree, surface scratches of the steel tube are reduced in the rolling process, and quality is improved. The novel four-roller guiding device, disclosed by the utility model, has the advantages of simple structure, good processing quality, good stability and the like.
Description
Technical field
The utility model relates to a kind of seamless steel pipe device structure, especially a kind of novel four roller guide devices.
Background technology
At present, in the existing seamless steel pipe complete set of equipments, milling train backstage guider is a mode of utilizing the guide employing bearing pin installation of different size; Be fixed on the base; Reached the guide effect of hollow forging, but whipping is bigger when producing the oil jacket steel pipe, has a strong impact on steel tube surface quality.
Summary of the invention
The purpose of the utility model is to change in the seamless steel pipe complete set of equipments, the design defect of milling train backstage guide equipment scratch steel tube surface, thus design a kind of simple in structure, novel four roller guide devices that crudy is good.The technical scheme of the utility model is so to realize:
A kind of novel four roller guide devices comprise base and guiding mechanism, and said guiding mechanism comprises the roller of roller-way seat and four symmetric arrangement provided thereon, and the roll surface of said four rollers is all tangent with the rewinding circle.
As preferably, said roller-way seat bolt is connected on the base.
The novel four roller guide devices of the utility model design are distributed on the roller-way seat by four groups of rollers, and four roller roll surfaces and required guide circle are tangent; Form closed hoop, steel tube surface is rotated with four groups of rollers in the operation of rolling, has restricted the whipping coefficient of steel pipe; Reduce the significantly whipping of hollow forging when rolling; Thereby improved the thread quality of product to a certain extent, also can in the operation of rolling, reduce the galled spots of steel pipe, improved the quality.Therefore the utlity model has simple in structure, characteristics such as crudy good, good stability.
Description of drawings
Accompanying drawing is a kind of structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing,, do further bright specifically to the technical scheme of the utility model through embodiment.
Embodiment: with reference to accompanying drawing, a kind of novel four roller guide devices comprise base 3 and guiding mechanism, and said guiding mechanism comprises the roller 2 of roller-way seat 1 and four symmetric arrangement provided thereon, and the roll surface of said four rollers 2 is that steel tube surface is tangent with rewinding circle 4 all.Said roller-way seat 1 bolt is connected on the base 3.
Steel pipe gets into when leading between four rollers 2 in the operation of rolling; Steel tube surface contacts with the roll surface of four rollers 2; Steel pipe is when rolling rotation and roller 2 friction; Make to be rolling friction between steel pipe and the roller, thereby restricted the whipping amplitude of steel pipe, thereby reduced the galled spots and the bump injury of steel pipe.
Claims (2)
1. novel four roller guide devices comprise base (3) and guiding mechanism, it is characterized in that said guiding mechanism comprises the roller (2) of roller-way seat (1) and four symmetric arrangement provided thereon, and the roll surface of said four rollers (2) is all tangent with rewinding circle (4).
2. a kind of novel four roller guide devices according to claim 1 is characterized in that said roller-way seat (1) bolt is connected on the base (3).
