Abstract
One subtracts sizing roll inlet guide, belongs to roll guide and guard equipment technical field, splits fault generation for avoiding subtracting size rolls in rolling 17-20mm large gauge medium high carbon cold-forging steel process.Its technical scheme is: its guide and guard import plug-in unit is arranged on the rear portion of guide and guard cavity, guide and guard outlet plug-in unit is arranged on the front portion of guide and guard cavity, guide and guard import plug-in unit has guide hole to be connected with the center of guide and guard outlet plug-in unit respectively, and the guide hole entrance point of guide and guard import plug-in unit is tapered inlet.The utility model adopts sliding guide to instead of the rolling guide of prior art, sliding guide can more press close to collars groove, closer to groove when making workpiece front end depart from guide and guard, effectively can alleviate the impact of workpiece front end near pass notch, avoid subtracting size rolls and split fault and produce.The utility model structure is simple, easy for installation, and the roller can eliminated in the rolling 17-20mm large gauge medium high carbon cold-forging steel operation of rolling splits problem, promotes the end product quality of large gauge cold-forging steel.
Description
Technical field
The utility model relates to the roll inlet guide used in a kind of rolling 17-20mm large gauge medium high carbon cold-forging steel process, belongs to roll guide and guard equipment technical field.
Background technology
In wire rod production process, need to be rolled on milling train, the guide and guard be arranged on before and after roll pass can help rolled piece exactly, stably enter by set direction and state and derive roll pass.Guide and guard divide rolling guide and sliding guide, and they respectively have pluses and minuses, are applicable on different milling trains.All will use guide and guards in the import of all rolls with outlet, its effect makes rolled piece according to required state turnover pass, can ensure that rolled piece is rolled by namely fixed deformation condition.If the design of guide and guards or improper use, just can not shut out qualified product, and may cause to scrape and cut rolled piece, squeeze steel, curling round the roll, even cause roll breakage or serious equipment breakdown and personal injury.In the processes such as rolling 17-20mm large gauge medium high carbon cold-forging steel ML40Cr, SCM435, GCr15, often occur that subtracting size rolls splits situation, by analysis reason mainly large gauge cold-forging steel nip subtract sizing roll time head temperature lower, the inlet of rolling mill rolling guide of current use is away from groove, workpiece front end is nipped and is impacted larger to notch instantaneously, roll just there will be the situation of notch place cracking, and then occurs that heap steel or finished product scab defective products.
Utility model content
Technical problem to be solved in the utility model is to provide one and subtracts sizing roll inlet guide, this roll inlet guide can make workpiece front end depart from guide and guard time closer to groove, effectively alleviate the impact of workpiece front end near pass notch, avoid subtracting size rolls and split fault generation.
The technical scheme solved the problems of the technologies described above is:
One subtracts sizing roll inlet guide, it is exported plug-in unit formed by guide body, guide and guard import plug-in unit, guide and guard, guide body center is guide and guard cavitys along the axis of guide body, guide and guard import plug-in unit is arranged on the rear portion of guide and guard cavity, guide and guard outlet plug-in unit is arranged on the front portion of guide and guard cavity, the center of guide and guard import plug-in unit and guide and guard outlet plug-in unit has the guide hole of the axis along guide body respectively, the guide hole rear end that guide hole front end and the guide and guard of guide and guard import plug-in unit export plug-in unit is connected, and the guide hole entrance point of guide and guard import plug-in unit is tapered inlet.
Above-mentionedly subtract sizing roll inlet guide, described guide and guard import plug-in unit and guide and guard outlet plug-in unit are that bolt is connected or key connects with guide body.
Above-mentionedly subtract sizing roll inlet guide, the guide hole of the guide hole of described guide and guard import plug-in unit or guide and guard outlet plug-in unit has tapering, and the guide hole diameter of guide and guard import plug-in unit is greater than the guide hole diameter of guide and guard outlet plug-in unit.
The beneficial effects of the utility model are:
The utility model adopts sliding guide to instead of the rolling guide of prior art, sliding guide can more press close to collars groove, closer to groove when making workpiece front end depart from guide and guard, effectively can alleviate the impact of workpiece front end near pass notch, avoid subtracting size rolls and split fault and produce.The utility model structure is simple, easy for installation, and the roller can eliminated in the rolling 17-20mm large gauge medium high carbon cold-forging steel operation of rolling splits problem, reduces the technology trouble when rolling large-size medium high carbon cold-forging steel, promotes the end product quality of large gauge cold-forging steel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model.
In figure, mark is as follows: guide body 1, guide and guard import plug-in unit 2, guide and guard outlet plug-in unit 3, guide hole 4, tapered inlet 5, bolt 6, key 7, alignment pin 8.
Detailed description of the invention
The utility model is exported plug-in unit 3 formed by guide body 1, guide and guard import plug-in unit 2, guide and guard.
Fig. 1,2 displays, guide body 1 center is guide and guard cavitys along the axis of guide body 1, guide and guard import plug-in unit 2 is arranged on the rear portion of guide and guard cavity, guide and guard outlet plug-in unit 3 is arranged on the front portion of guide and guard cavity, the center of guide and guard import plug-in unit 2 and guide and guard outlet plug-in unit 3 has guide hole 4 along the axis of guide body 1 respectively, and guide hole 4 rear end that guide hole 4 front end and the guide and guard of guide and guard import plug-in unit 2 export plug-in unit 3 is connected.Guide and guard import plug-in unit 2 and guide and guard outlet plug-in unit 3 form sliding guide, instead of the rolling guide of prior art, sliding guide can more press close to collars groove, make workpiece front end depart from guide and guard time closer to groove, effectively can alleviate the impact of workpiece front end near pass notch, avoid subtracting size rolls and split fault generation.
Fig. 1,2 displays, guide hole 4 entrance point of guide and guard import plug-in unit 2 is tapered inlet 5, is conducive to the guide hole 4 that rolled piece enters guide and guard import plug-in unit 2.
Fig. 1 shows, and a kind of structure of the present utility model is that the guide hole 4 of guide and guard import plug-in unit 2 and the guide hole 4 of guide and guard outlet plug-in unit all have tapering, and guide hole 4 diameter of guide and guard import plug-in unit 2 is greater than guide hole 4 diameter of guide and guard outlet plug-in unit 3.Guide and guard import plug-in unit 2 is connected for key 7 with guide body 1 with guide and guard outlet plug-in unit 3.
Fig. 2 shows, and another kind of structure of the present utility model is the guide hole 4 of guide and guard import plug-in unit 2 is equal diameter, and the guide hole 4 of guide and guard outlet plug-in unit has tapering, and guide hole 4 diameter of guide and guard import plug-in unit 2 is greater than guide hole 4 diameter foremost of guide and guard outlet plug-in unit 3.Guide and guard outlet plug-in unit 3 is connected for bolt 6 with guide body 1.
The roll inlet guide of these two kinds of structures goes for different milling trains or rolled piece.
