Abstract
The utility model discloses a guide roller wheel device for a large ring rolling machine. The guide roller wheel device comprises a first guide roller wheel, a second guide roller wheel, a third guide roller wheel and an embracing arm, wherein the first guide roller wheel, the second guide roller wheel and the third guide roller wheel are hinged to the embracing arm, the thickness of the third guide roller wheel is two third of the total thickness of the first guide roller wheel and the second guide roller wheel, the first guide roller wheel is arranged on the second guide roller wheel, and the second guide roller wheel is positioned on the third guide roller wheel. The guide roller wheel device for the large ring rolling machine is simple in structure and reliable in performance, prevents moulds from climbing in equipment operation, increases stability, reduces noise and improves workpiece quality.
Description
Technical field
The utility model relates to a kind of large-scale seamless ring hot-roll forming equipment, i.e. the axial ring rolls in large-sized numerical control footpath, specifically armful roller apparatus of the axial ring rolls in a kind of large-sized numerical control of more reasonable structure footpath.
Background technology
The large-sized numerical control footpath-axially ring rolls is the special equipment of large-scale seamless ring hot-roll forming, namely by applying footpath, axial rolling force to heating rear blank, realizes the shaping of wall thickness reduction, enlarged-diameter, cross section profile.
The roller apparatus of embracing of large-scale ring rolls originally is comprised of arm, first armful of running roller, the second running roller, the 3rd armful of running roller, the thickness of first armful of running roller, the second running roller, the 3rd armful of running roller all is the same, during the equipment operation, processing mold, mould is pole-climbing always, poor stability, and noise is large, and parts quality is low.
The utility model content
The purpose of this utility model is in order to solve the technological deficiency of present existence, problem for the prior art existence, the utility model provide a kind of simple in structure, dependable performance the large-sized numerical control ring rolls embrace roller apparatus, not pole-climbing of mould during the equipment operation, stability increases, noise reduces, and improves parts quality.
The technical scheme that the utility model adopts is: armful roller apparatus of large-scale ring rolls, comprise first armful of running roller, second armful of running roller, the 3rd armful of running roller, arm, described first armful of running roller and described arm are hinged, described second armful of running roller and described arm are hinged, described the 3rd armful of running roller and described arm are hinged, and the thickness of described the 3rd armful of running roller is 2/3rds of described first armful of running roller, described second armful of running roller gross thickness.
As preferably, described first armful of running roller is located on described second armful of running roller, and described second armful of running roller is located on described the 3rd armful of running roller.
The beneficial effects of the utility model are, the utility model provide a kind of simple in structure, dependable performance the large-sized numerical control ring rolls embrace roller apparatus, not pole-climbing of mould during the equipment operation, stability increases, noise reduces, and improves parts quality.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
The specific embodiment
In order to deepen that understanding of the present utility model is described in further detail the utility model below in conjunction with drawings and Examples.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, 2, armful roller apparatus of the large-scale ring rolls that the utility model provides, comprise first armful of running roller 1, second armful of running roller 2, the 3rd armful of running roller 3, arm 4, first armful of running roller 1 is hinged with arm 4, second armful of running roller 2 is hinged with arm 4, the 3rd armful of running roller 3 is hinged with arm 4,2/3rds of first armful of running roller of the thickness of the 3rd armful of running roller 3, second armful of running roller gross thickness.First armful of running roller 1 is located on second armful of running roller 2, and second armful of running roller 2 is located on the 3rd armful of running roller 3.
Specific embodiment of the utility model is that the roller apparatus of embracing of large-scale ring rolling machine is originally that first armful of running roller, second armful of running roller, the 3rd armful of running roller all are of uniform thickness, during the equipment operation, processing mold, mould is pole-climbing always, poor stability, and noise is large, and parts quality is low.Through improving the thickness of the 3rd armful of running roller is increased by 1/3rd now, not pole-climbing of mould during the equipment operation, stability increases, and noise reduces, and has improved parts quality.
Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modifications that are equal to replacement or make according to prior art of affiliated technical field those of ordinary skill, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
