Embodiment 1
Then, the concrete structure of steering hardware is described.Fig. 2 is the birds-eye view of the steering hardware of embodiment 1 of the present utility model.Fig. 3 is the front view of the steering hardware of embodiment 1 of the present utility model, and Fig. 4 is the block diagram of the steering hardware of embodiment 1 of the present utility model.In Fig. 2 to Fig. 4, steering hardware 60 carries out 90 ° turning to bands for band material, but the steering hardware shown in Fig. 2 to Fig. 4 also can be applied to the situation that steering angle is other angles.
As shown in Figure 3, steering hardware 60 is fixed on ground etc. by base 61 and arranges on object, and one end of support 62 is vertically fixed on base 61, and the other end is fixedly connected with slewing rollers pedestal 63 by four the full bolts 64 and the nut 65 that are located at four jiaos of upper surfaces.Here, be provided with four full bolts 64 and nut 65 at the rectangle upper surface of support 62 four jiaos, but can change by quantity and the setting position to full bolt and nut according to the shape of the upper surface of support 62 and size.Certainly, support 62 is also not limited to bolt and nut with the connection mode of slewing rollers pedestal 63 and is connected, as long as the distance between upper surface and the slewing rollers pedestal 63 of adjusting pole 62 freely.
Be provided with the S. A. 66 that can rotate freely around axes O in the substantial middle of slewing rollers pedestal 63, slewing rollers 67 are fixed on S. A. 66 in the mode of following S. A. 66 and rotating together.In addition, as shown in Figures 3 and 4, S. A. 66 is fixed in one end of slewing rollers 67, but the other end is free end, is cantilevered construction, but in the situation that tension force is larger, also can be set to two ends all in the two ends of stationary state stationary structure.
In addition, the convex edge 68 that external diameter is larger than the external diameter of slewing rollers 67 is set in the lower end of slewing rollers 67, this convex edge 68 is radially outwards outstanding from the outer peripheral face of slewing rollers 67.Owing to being provided with this convex edge 68, thereby the back side of bands for band material obtained support, and bands for band material is difficult for falling from slewing rollers 67 because of the effect of gravity etc.In addition, in the utility model, the external diameter of slewing rollers 67 is set as diminishing gradually towards the one end that is provided with convex edge 68 (lower end), is formed as rounding taper type.By being formed as rounding taper type, in the time that bands for band material is turned to, can apply the downward component of pressing to bands for band material, can prevent reliably that bands for band material from floating, maintain the stable posture of advancing.
For fear of because the friction between bands for band material and the outer peripheral face of slewing rollers 67 causes damage to bands for band material, in the present embodiment, on the outer peripheral face of slewing rollers 67, be provided with clad material.This clad material is soft metal, resin, fiber or the composite material that is made up of these materials.The material that this clad material preferred hardness is lower than the hardness of bands for band material, thereby can give full play to the effect that prevents bands for band material damage.
In the present embodiment, more than the external diameter of slewing rollers 67 is set as 235mm, more than being preferably 300mm.Thus, can reduce the distortion that steering procedure produces in bands for band material.
The distortion producing in bands for band material is to produce because of the bending torque that slewing rollers 67 impose on bands for band material.Calculate according to the yield stress of conventional bands for band material, vertical elasticity modulus etc., the external diameter 235mm of known slewing rollers 67 just can reach the effect of the permanent deformation of inhibition zone saw blade material above.
Fig. 5 has represented the external diameter of slewing rollers and the figure of the experimental result of the relation of the set deformation volume of the bands for band material passing through.The bands for band material that experiment is used is respectively width 54mm × thickness 1.6mm, width 67mm × thickness 1.6mm, this three types of width 80mm × thickness 1.6mm.The tension force of bands for band material webs during around to slewing rollers 67 is 50kg, and the material of main part of bands for band material is modified material and has carried out cutting and point tooth processing.
In addition, the measuring method of deflection is, in bands for band material webs, after slewing rollers, the deflection of the thickness direction to winding part is measured with identical condition, and the maxim that mensuration is obtained is made as 100%.
As shown in Figure 5, along with the increase of slewing rollers external diameter, the set deformation volume producing in bands for band material reduces, if as the slewing rollers 67 in the present embodiment, more than external diameter is set in 300mm, the set deformation volume producing in bands for band material is almost nil.The thickness of the bands for band material using in experiment is in addition all 1.6mm, but because the thickness set deformation volume that more small property is given birth to is less, so the thin bands for band material (0.9mm, 1.1mm, 1.3mm, 1.6mm) of Thickness Ratio 1.6mm also can obtain identical set deformation volume inhibition.
In addition, be that thickness is on Width uniformly when bands for band material at bands for band material, the width of slewing rollers 67 is arbitrarily set according to design specification, but be to have carried out the bands for band material of point tooth processing or the processing of cutting edge material joint at bands for band material, preferably the width of slewing rollers 67 is below the width of bands for band body of material portion (except the abapical part of tooth).By such setting, just can avoid the crown part because protruding from bands for band body of material portion to contact crown part is caused to damage with slewing rollers 67.
In bands for band material traveling process, because the height of each processing unit (plant), steering hardware or guiding tension device etc. produces deviation, the back side of bands for band material likely occurs and the uneven situation in ground (object is set), also may occur needing according to the coupled condition of each device the uneven situation of course and ground (object is set) of bands for band material.In addition, when bands for band material contacts with steering hardware, likely upwards float, cannot be in stable state.In the present embodiment, in order to make travel angle that steering hardware can adaptive zone saw blade material, to prevent that bands for band material from upwards floating, steering hardware possesses the structure that slewing rollers 67 upwards can both more freely tilt in whole week.In the above-described embodiment, be arranged on full bolt 64 and the nut 65 of four jiaos by adjustment, can adjust the heeling condition of S. A. 66.
