Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
As shown in Fig. 3,4,5, oblique milling tube mill outlet device of the present invention comprises support 10, three main transmission universal-joint spindles 20, two guide rollers 30, two bearing blocks 40 and export orientation structure 50, be provided with bearing 41 in bearing block 40, the axle (not shown) of guide roller 30 is connected to bearing 41.What guide roller 30 and bearing block 40 were all symmetrical is located on support 10, and bearing block 40 is connected with guide roller 30, for being supported over the mount 10 by guide roller 30.
As shown in Figure 5, export orientation structure 50 comprises guidance part 51, support portion 52 and connecting portion 53.Support portion 52 has roughly V-shaped supporting surface S1, comprise the first inclined-plane 521, bottom surface 522 and the second inclined-plane 523, bottom surface 522 is rectangle, first inclined-plane 521 and the second inclined-plane 523 respectively from the two ends of bottom surface 522 mutually away from inclination, and form connecting portion 53 towards the outside horizontal-extending of support portion 52 further.The end of connecting portion 53 forms the lug 531 with through hole 532.Support portion 52 and connecting portion 53 are by solder bond.
As shown in Fig. 6,8, guidance part 51 has the metal derby of guiding face S2 for upper surface, guiding face S2 comprises the first guiding face 511, second guiding face 512 and the 3rd guiding face 513, first guiding face 511 and the 3rd guiding face 513 and extends obliquely from the both sides of the second guiding face 512.As shown in Figure 8, first guiding face 511, second guiding face 512 and the 3rd guiding face 513 all tilt towards the front side of guidance part 51, the front of guidance part 51 is made to have open front 514, rear has after-opening 515, the subtended angle A of open front 514 is greater than the subtended angle B of after-opening 515, makes guidance part 51 present pre-large post-small toroidal.Support portion 52 is welded in the rear side of guidance part 51, and supporting surface S1 is alignd with guiding face S2, and the subtended angle of supporting surface S1 equals or slightly larger than the subtended angle B of after-opening 515.
Export orientation structure 50 is positioned on support 10, be specially, the top of bearing block 40 is located in support portion 52, cover bearing block 40 completely, the lug 531 of connecting portion 53 exposes from the both sides of support 10, corresponding to the position of lug 531, respectively welds a projection 11 in the both sides of support 10, projection 11 is arranged a bearing pin 12, make bearing pin 12 through through hole 532.Bearing pin 12 offers perforation 121, and the upper surface (not shown) of perforation 121 is inclined-plane, and the present embodiment is the cambered surface with gradient.Chadless 121 exposes from the upper surface of lug 531.During installation, make that lug 531 is corresponding with bearing pin 12 to be arranged, bearing pin 12 is through the through hole 532 of lug 531.Penetrate in perforation 121 with wedge 13, and the inclined-plane of the wedge 13 penetrated presses with the inclined-plane of perforation 121, forces wedge to be pressed in the upper surface of the lug 531 around bearing pin 12 for 13 times, thus export orientation structure 50 is fixed on support 10.
In order to improve the stability of export orientation structure 50, export orientation structure 50 is fixed on after on support 10, over the mount 10, presses the lower surface welding block 60 of export orientation structure 50, by welding block 60 pushing for export orientation structure 50, make outlet guide frame 50 more firm.
In work, when steel pipe 5 rushes at guide roller 30, the guiding face S2 of toroidal is towards steel pipe 5, make it can contact with the first guiding face 511, second guiding face 512 and/or the 3rd guiding face 513, and guided by guiding face S2, then slide on supporting surface S1, finally drop on the guide roller 30 at rear.As shown in Figure 5, because the toroidal of guiding face S2 designs, can guide the steel pipe of different size.Therefore, whole process steel pipe 5 all can not collide with bearing block 40, and can is directed on guide roller 30 smoothly, is supported, is led, leave oblique milling tube mill by the guide roller 30 rotated.
Preferably, support portion 52 is connected for dismountable with guidance part 51, or on guiding face S2, arrange interchangeable steel plate, is preferably the steel plate that hardness is higher, wear-resisting, when collision causes guiding face impaired to steel pipe 5 for a long time, is convenient to change it.
Therefore, the present invention is that oblique milling tube mill outlet device provides the simple export orientation structure of a kind of structure, its guiding of guidance part by toroidal steel pipe, and can alleviate the impulsive force of steel pipe to roller-way, thus improve the force-bearing situation of roller-way, make the rolling course of work can be more steady; And the bearing of whole support, bearing block and the inside is covered by support portion, avoid steel pipe and bearing block to collide, thus make equipment use more firm, extend bearing service life, objectively reduce the cost of manufacture of producing product.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
