Description
Technical field
The utility model belongs to vertical kink field, particularly relates to a kind of novel vertical loop pressure roller mechanism.
Background technology
Vertical kink is widely used on bar and wire rod rolling process line.In rolling process, by the interoperation of kink loop-rising roll and pressure roller, make to realize second flow between each frame equal, thus realize tension free rolling, eliminate the accumulation of steel between adjacent milling train or the tension force caused by tensioning.
The pressing roll mechanism of kink is positioned at the two ends of kink, and its effect is by press-roller device and the tightness of interaction (both sides are pressed, and centre is chosen) regulating rod wire rod between milling train playing covering device, finally realizes the control to " second flow ".The function of press-roller device is: on the one hand, pressing roll mechanism want to regulate press highly; On the other hand, after highly determining, press-roller device will ensure the stability of compression roller heights.
The structure of existing loop pressure roller mechanism as shown in Figure 1, mainly fix pressure roller by pressing roller holder, by (as Figure 2-3) turn in the screwed hole of bolt on pressing roller holder, control the adjustable height of pressing roller holder, rely on the frictional force of wedge and pressing roller holder to compress support.From the relevant knowledge of theory of mechanics, above-mentioned wedge does not have self-lock ability at this place, only can provide certain frictional force.Because pressure roller can bear at work into whipping power when impulsive force during steel and tapping.Under the effect of discontinuity impulsive force, above-mentioned compressing structure often loosens, and makes loop pressure roller job insecurity, causes serious consequences such as " pier steel ".
Summary of the invention
The utility model, for above-mentioned technical problem, provides a kind of structure simple, practical novel vertical loop pressure roller mechanism.
The technical scheme that the utility model adopts is:
A kind of novel vertical loop pressure roller mechanism, it is characterized in that: comprise kink body, pressing roller holder, wedge, stud, first top nut, second top nut, lower nut, the upper end of described kink body offers locating hole, described pressing roller holder is installed on described kink body, the top of described pressing roller holder offers unthreaded hole, the bottom of described pressing roller holder is provided with pressure roller assembling, described wedge is installed on described kink body and its laminating is arranged at the side of described pressing roller holder, the middle part of described stud is inserted in described unthreaded hole and its lower end is welded in described locating hole, described first top nut, second top nut is installed on described stud and it lock onto the top of described pressing roller holder, described lower nut is installed on described stud and it lock onto the below of described pressing roller holder.
Described first top nut, the second top nut laminating are arranged.
Described wedge laminating is arranged at the side, middle part of described pressing roller holder.
The beneficial effects of the utility model are:
1, modified node method is passed through, former bolt is changed into the stud being welded in kink body, former bolt hole simultaneously on pressing roller holder changes unthreaded hole into, the first top nut on stud, the second top nut realize locking when withstanding shocks power, the frictional force provided by wedge during the power that is not hit compresses pressing roller holder, by the lower nut below pressing roller holder on stud, realize the lifting of pressing roller holder;
2, the utility model is improved by simple structure, ensure that the stability of pressure roller duty, effectively solving the phenomenon that pressure roller " jumps roller or loose roller " when withstanding shocks power, retaining the advantage that also effectively make use of former roller structure simultaneously, structure is simple, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing loop pressure roller mechanism;
Fig. 2 is the main TV structure schematic diagram of existing pressing roller holder;
Fig. 3 is the side-looking structural representation of existing pressing roller holder;
Fig. 4 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
In figure, 1-bolt, 2-nut, 3-wedge, 4-block, 5-pressure roller assembles, 6-kink body, 7-pressing roller holder, 8-guide pad, 9-plays covering device, 10-screwed hole, 11-stud, 12-first top nut, 13-second top nut, 14-lower nut, 15-locating hole, 16-unthreaded hole.
Embodiment
As shown in Figure 4, a kind of novel vertical loop pressure roller mechanism, comprise kink body 6, pressing roller holder 7, wedge 3, stud 11, first top nut 12, second top nut 13, lower nut 14, the upper end of kink body 6 offers locating hole 15, pressing roller holder 7 is installed on kink body 6, the top of pressing roller holder 7 offers unthreaded hole 16, the bottom of pressing roller holder 7 is provided with pressure roller assembling 5, wedge 3 is installed on kink body 6 and its laminating is arranged at the side of pressing roller holder 7, the middle part of stud 11 is inserted in unthreaded hole 16 and its lower end is welded in locating hole 15, first top nut 12, second top nut 13 is installed on stud 11 and it lock onto the top of pressing roller holder 7, lower nut 14 is installed on stud 11 and it lock onto the below of pressing roller holder 7.
First top nut 12, second top nut 13 laminating is arranged.
Wedge 3 laminating is arranged at the side, middle part of pressing roller holder 7.
As Figure 1-4, change former No. 1 part bolt 1 into stud 11, after strengthening diameter of thread car positioning table, be welded in the corresponding locating hole 15 of kink body 6, change lifting screwed hole 10 former on pressing roller holder 7 into unthreaded hole 16, on dependence stud 11 on pressing roller holder 7, first top nut 12 of below, second top nut 13, lower nut 14, promote and location pressing roller holder 7, wherein because stud 11 is welded on kink body 6, the first top nut 12 above pressing roller holder 7, locking effect is played again in second top nut 13, under two nuts above pressing roller holder 7 and the acting in conjunction of wedge 3, the work of pressure roller is more reliable and more stable.
Above 1 embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
