The rust remover roller
Technical field
The utility model relates to a kind of roller, and especially a kind of rust remover roller belongs to the technical field of rust remover.
Background technology
In the Steel Wire Products Industry, no matter be the wire drawing of wire rod or the boronation before the wire drawing is handled or annealed wire zinc-plated, all will remove the oxide layer of wire rod or Steel Wire Surface, with the carrying out of guaranteeing wire-drawing operation or the fastness and the light of zinc coat.Steel wire need carry out alignment before rust cleaning.Rust remover comprises roller and is positioned at abrasive band on the roller, and the rotation of roller drives the abrasive band and rotates, thereby to the steel wire rust cleaning of polishing.At present, the roller of rust remover is installed inconvenient; The service life of roller is short, influences the rust cleaning of the abrasive band of rust remover to steel wire.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of rust remover roller is provided, and it is simple in structure, and is easy to install, has prolonged the service life of roller, has reduced use cost, safe and reliable.
According to the technical scheme that the utility model provides, described rust remover roller comprises roller body; Described roller body is cydariform.
The material of described roller body comprises aluminium alloy.One end of described roller body is provided with first installing hole, and roller body is provided with second installing hole corresponding to the other end that first installing hole is set; The axis of described first installing hole, second installing hole and the axis of roller body are located along the same line; First installing hole is connected with second installing hole.
The aperture of described first installing hole is greater than the aperture of second installing hole.The length of described second installing hole is greater than the length of first installing hole.
Described roller body is provided with positioning spline corresponding to the end that second installing hole is set, and described positioning spline is along the distribution of lengths of second installing hole, and the bottom land of positioning spline is connected with second installing hole.
Advantage of the present utility model: roller body is cydariform, can cooperate with the abrasive band on being positioned at the roller body outer peripheral face is more effective; Be provided with first installing hole and second installing hole in the roller body, roller body also is provided with positioning spline corresponding to the end that second installing hole is set, and roller body can be installed on the roller installation shaft easily; Simple in structure, easy to install, prolonged service life of roller, reduced use cost, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1 ~ shown in Figure 2: the utility model comprises roller body 1, first installing hole 2, second installing hole 3 and positioning spline 4.
As depicted in figs. 1 and 2: the profile of described roller body 1 is cydariform, and when roller body 1 adopted cydariform, roller body 1 can better contact with abrasive band on being positioned at roller body 1.Roller body 1 adopts aluminium alloy to make, and has improved the intensity of roller body 1.One end of roller body 1 is provided with first installing hole 2, and roller body 1 is provided with second installing hole 3 corresponding to the other end that first installing hole 2 is set, and described first installing hole 2 is connected with second installing hole 3.The aperture of described first installing hole 2 is greater than the aperture of second installing hole 3, and the length of second installing hole 3 is greater than the length of first installing hole 2.Be provided with positioning spline 4 corresponding to the end that second installing hole 3 is set in the roller body 1, described positioning spline 4 is along the distribution of lengths of second installing hole 3; The bottom land of positioning spline 4 is connected with second installing hole 3; And the locating piece on described positioning spline 4 and the roller installation shaft is complementary.
As depicted in figs. 1 and 2: during use, be provided with the roller installation shaft in the described roller body 1, an end of described roller installation shaft stretches in second installing hole 3 of roller body 1; Roller body 1 is utilized positioning spline 4 and the corresponding cooperation of roller installation shaft; The roller installation shaft stretches into the joint portion of second installing hole 3 and first installing hole 2.The roller installation shaft utilizes back-up ring, packing ring and screw and roller body 1 to fix corresponding to the joint portion of stretching into second installing hole 3 and first installing hole 2, guarantees the bonding strength of roller body 1 and roller installation shaft.The roller installation shaft links to each other with rolling disc, cover plate corresponding to the other end that links to each other with roller body 1, and when rolling disc and cover plate rotate, can drive roller installation shaft and roller and rotate, thus can be with the abrasive band transmission on roller body 1 outer peripheral face.Can polish to steel wire after rotating in the abrasive band, remove the oxide layer of Steel Wire Surface.
The utility model roller body 1 is cydariform, can with more effective cooperation of abrasive band on being positioned at roller body 1 outer peripheral face; Be provided with first installing hole 2 and second installing hole 3 in the roller body 1, roller body 1 also is provided with positioning spline 4 corresponding to the end that second installing hole 3 is set, and roller body 1 can be installed on the roller installation shaft easily; Simple in structure, easy to install, prolonged service life of roller, reduced use cost, safe and reliable.
