Description
Technical field
The present invention relates to the technical field of steel rolling equipment, be specifically related to a kind of round bar shaped loop-mill rolling and use rolling guide.
Background technology
Kink is a device the most frequently used in line, the bar mill, is divided into horizontal kink, upright kink and side kink.Loop-mill rolling is meant that bar shaped is simultaneously on two above milling trains when rolling; Because the second flow amount during through each frame does not wait; Side arm second flow amount greater than after-frame and form the milling method of the U type accumulation (being kink) that enlarges gradually; Purpose is in order to eliminate bar shaped tension force, to guarantee line, bar dimensional accuracy of products.In line, the bar mill bar shaped of loop-mill rolling modal be oval bar shaped and the circle bar shaped.For circle bar shaped loop-mill rolling, more common at present rub root type milling train and western mark's type milling train, the root type that wherein rubs milling train generally uses sliding guide; West mark type milling train is general, and what use is rolling guide, at the front end of guide and guard a pair of deflector roll is set, and deflector roll is arranged according to above-below direction.More than two kinds of round bar shaped loop-mill rollings use guide and guard; Its shortcoming all is effectively to control the movement locus of bar shaped; So bar shaped can not accurately get into pass; Often produce the monolateral ears or side handles of a utensil and go out waste product, loop-mill rolling is not scraped steel and steel bonding phenomenon owing to there is tension force on the upper and lower sides guide and guard pair of guide and guard, to produce easily yet, and these all are the problems that present common guide and guards does not have fine solution.For production high added value wire product; Such as being the factory that exempts to anneal, simplify cold-forging steel products such as annealing and non-accent steel that produces high cold heading performance; Shape need to bar shaped in the operation of rolling is high especially, and the 0.05mm fine cracks all can cause the defective of cold-forging steel finished product cold-heading test on the finished product.Rolling regional bar shaped in also being has the cut greater than 0.2mm, is reflected in to be pressing property crack on the finished product, and naked eyes are difficult to find that shutting out the finished product that comes just possibly be waste product, very easily causes the quality of lot accident.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and can control the bar shaped movement locus; Thereby make bar shaped can accurately get into pass; Can not produce the monolateral ears or side handles of a utensil and go out waste product, and can not produce the round bar shaped loop-mill rolling of scraping steel and steel bonding phenomenon and use rolling guide.
For addressing the above problem, the technical scheme that the present invention adopts is: circle bar shaped loop-mill rolling is used rolling guide, comprises the box body of a hollow; The set inside of box body has guide plate; Be provided with a passage in the described guide plate, the front end of box body is provided with a pair of preceding deflector roll, and described a pair of preceding deflector roll is arranged according to left and right directions; Gap between the described a pair of preceding deflector roll is over against the passway of guide plate; The rear end of box body is provided with a pair of back deflector roll, and described a pair of back deflector roll is arranged according to above-below direction, and the gap between the deflector roll of described a pair of back is over against the passway of guide plate.
Deflector roll comprises left deflector roll and right deflector roll before described; Described left deflector roll is connected with right support arm with left support arm with preceding deflector roll lock clasp nut through preceding deflector roll bearing pin respectively with right deflector roll; Described left support arm is connected with box body through the support arm bearing pin respectively with right support arm; Be provided with support arm through screw thread respectively on the described support arm bearing pin and adjust nut up and down, described left support arm and right support arm are provided with groove, and described support arm is adjusted nut up and down and is embedded in groove; Be respectively arranged with support arm opening adjustment screw on described left support arm and the right support arm; Described support arm opening adjustment screw has four, and is arranged on the sidepiece of left support arm and right support arm before and after in twos respectively, and each support arm opening adjustment screw top is respectively arranged with locking nut.
Described back deflector roll comprises deflector roll and lower guide roll, and described upward deflector roll and lower guide roll are arranged in the deflector roll bearing of back through back deflector roll bearing pin and back deflector roll lock clasp nut respectively, and back deflector roll bearing is connected with the rear end of box body.
Described guide plate holds out against screw through guide plate and box body fixes.
The top of described box body is provided with pressing plate, and pressing plate is provided with the pressing plate locking nut, and pressing plate is pressed on the support arm bearing pin.
The invention has the beneficial effects as follows: above-mentioned round bar shaped loop-mill rolling is used rolling guide; Be respectively arranged with four deflector rolls up and down in front and back; Thereby can effectively control the movement locus of bar shaped; Make bar shaped can accurately get into pass, can not produce the monolateral ears or side handles of a utensil and go out waste product, and can not produce and scrape steel and steel bonding phenomenon.
