Abstract
The utility model relates to a round-bar-type vertical looper rolling guide and guard device used for rolling mill, especially relates to the guide and guard device used for the rolling mill group of the stick, line continuous rolling mill, which includes roll guides and guide rollers, and is characterized in that: the level guide roller, vertical guide roller, support base is fixed to the cylinder roll guides in turn; the guide roller pair are fixed to a level guide roller bracket and a vertical guide roller bracket and extend into a roll guide chamber so as to form a square workpiece passage. In working, the support base is fixed on the rolling mill, and the moving workpiece is loaded from the rear of the support base and drives the guide roller to rotate, then smoothly enters into the hole mold under the vertical and level support of the guide rollers. The phenomena of generating unilateral ear on the workpiece and roll guide scratching and adhering the steel can be thoroughly avoided, therefore, the production quality can be guaranteed, and the wearing and the consume of the roll guide can be reduced therefore, the changing frequency of the roll guide and the shut-up time can be reduced accordingly, so the product efficiency can be enhanced. In addition, the utility model has the advantages as following: reasonable and compact structure, small volume, facilitation for detaching and maintain safety and reliable for use.
Description
Technical field
The utility model belongs to roller guide and guard unit, relate in particular to rod, wire rod continuous rolling mill in roll pre-finishing mill group import guide and guards.
Background technology
Rolling the pre-finishing mill group in rod, wire rod continuous rolling mill generally has three kinks, and a middle kink is a circle bar shaped kink, because the rolled piece bar forms movement in a curve, being provided with of guide and guard increased difficulty.What use at present is one group of vertical guide and guard.Its shortcoming is, can not control the side-to-side movement direction of rolled piece bar shaped, so that rolled piece can not accurately enter pass, and rolled piece often produces the monolateral ears or side handles of a utensil; Because loop-mill rolling does not have tension force, on guide and guard left and right sides guide and guard pair, produce easily and scrape steel, steel bonding phenomenon, influence product quality.Particularly produce high cold heading performance exempt from annealing, simple and easy annealing, and during high value added product such as non-hardened and tempered steel, the operation of rolling is high especially to the shape need of rolled piece bar shaped, it is defective that the 0.05mm fine cracks all may cause the product cold heading performance on the finished product, roll regional bar shaped in also being the cut greater than 0.2mm is arranged, being reflected on the finished product is the pressing crack, and shutting out the finished product that comes just may be waste product, very easily causes the quality of lot accident.
Summary of the invention
In order to overcome the shortcomings and deficiencies that background technology exists, the purpose of this utility model provides the upright kink rolling guide of a kind of round bar shaped, can accurately import roll with justifying the bar shaped rolled piece, avoids producing the monolateral ears or side handles of a utensil and guide and guard and scrapes steel, steel bonding phenomenon.
The upright kink rolling guide of circle bar shaped comprises guide and guard and deflector roll, and characteristics are that horizontal guide roller frame, vertical guide roll frame and bearing are fixed in the tubular guide and guard successively, fuse; The deflector roll pair is separately fixed on horizontal guide roller frame and the vertical guide roll frame, and stretches in the inner chamber of guide and guard, deflector roll pair on the horizontal guide roller frame and the square rolled piece passage of the secondary formation of deflector roll on the vertical guide roll frame.During use with bearing fixedly on the milling train, the rolled piece of motion is imported by the rear portion, the drive deflector roll rotates, since deflector roll on the horizontal guide roller frame and the deflector roll on the vertical guide roll frame by the bar shaped direction of motion about, upper and lower settings, rolled piece just enters pass swimmingly under the support of deflector roll, thereby thoroughly avoid the monolateral ears or side handles of a utensil of the monolateral generation of rolled piece bar shaped and guide and guard to scrape steel, steel bonding phenomenon, guaranteed product quality; Alleviate the guide and guard wearing and tearing, reduced guide and guard consumption, reduce and change guide and guard number of times and downtime, favourable enhancing productivity; That the utility model also has is rational in infrastructure, compact, volume is little, loading and unloading and advantage such as easy to maintenance, safe in utilization, reliable.
