Abstract
The invention relates to a swinging roller device with vertical and horizontal two-position function, comprising a free roller device, a lifting shaft mechanism, a thrust cylinder and a support. When the thrust cylinder stretches, the lifting shaft is driven to rotate, the lifting shaft drives the free roller device to rotate, so as to realize two positions of vertical support state while the free roller is in operation and horizontal non-support state while in flame cutting, namely vertical and horizontal two-position function of the free roller. When a flexible dummy bar is fed, the free roller is in the vertical position, thus well meeting the requirement of leading in and taking out the flexible dummy bar; and when the free roller is in horizontal position, the requirement of continuous cutting of a flame cutting machine can be well met, swinging is flexible, positioning accuracy is high, and maintenance is easy.
Description
Technical field
The present invention relates to a kind of oscillating roller device, be specially oscillating roller, belong to iron and steel metallurgical industry continuous-casting of steel billet technical field with vertical-horizontal dibit function to bloom, large round billet and the slab caster of flexible dummy bar.
Background technology
In the iron and steel metallurgical industry, on the continuous casting steel machine production line, strand comes out from crystallizer; In two cold-zone cooled and solidified, cut front roller-way through the entering of throwing aligning, cut the back roller-way through getting into again behind the flame cutting zone; Flame cutting machine cuts by the given size requirement; Because the cutting stroke of flame cutting machine requires institute limit, cut last roller of front roller-way with cut after distance between the most previous roller of roller-way bigger, general roller spacing greater than roller-way after cutting is a lot.For the conticaster that adopts flexible dummy bar, roller-way after dummy bar is cut from the rollgang entering is through flame cutting zone the time; Because of the interval of roller big; Cause flexible dummy bar front end to have sag to produce, flexible dummy bar can not get into through flame cutting zone smoothly and cut front roller-way this moment, therefore need between these two rollers, increase a transition supporting point; Guarantee that dummy bar gets into smoothly and cut front roller-way, get into crystallizer through straightening machine, fan-shaped section again.When opening when watering throwing; The dummy ingot headband of flexible dummy bar strand and is advanced to the throwing direction; The dummy bar afterbody through the straightening machine, cut front roller-way and get into flame cutting zone, pass through smoothly for the dummy bar afterbody this moment, also needs a dummy bar transition supporting point; Could guarantee that dummy bar gets into smoothly cuts the back roller-way, arrives rollgang and also deposits.On the other hand; When strand entering flame cutting zone cut, dummy bar transition supporting point must be removed, to guarantee that flame cutting machine cuts continuously; The protection strong point is not cut flame and burns out; Otherwise at the excessive supporting-point of dummy bar place, need stop cutting, wait strand to pass through to cut again behind this supporting-point.
The oscillating roller device of bloom, large round billet and the slab caster of the existing flexible dummy bar of known employing; Two oscillating roller devices about being; Upperly play the effect of dummy bar transition supporting, the continuous cutting of the next assurance flame cutting machine is because this oscillating roller swing arm is longer; Cause existing equipment in use fragile, and the reparation difficulty is big.China's utility model patent " the continuous casting cutting oscillating roller of anti-dry slag " (grant number CN201291294Y; Day for announcing 2009.08.19) only relates to the anti-dry slag device of a kind of cutting oscillating roller; The life cycle of can online removing dry slag, having improved operating efficiency and having prolonged oscillating roller; In the related patent U.S. Patent No., do not find about realizing the oscillating roller device of vertical-horizontal dibit function.
Summary of the invention
The object of the invention provides a kind of oscillating roller device with vertical-horizontal dibit function, and this has installed the effect of transition supporting flexible dummy bar, and its swing arm is short; Flexible swinging; Positioning accuracy is high, can satisfy the continuous split requirement of importing, derivation and the flame cutting machine of flexible dummy bar, and adaptability is good; Equipment is in use not fragile, and the reparation difficulty is little.
Technical scheme of the present invention is: have the oscillating roller device of vertical-horizontal dibit function, comprise free roller arrangement, lifting shaft mechanism, push action cylinder and bearing, described free roller arrangement is a cylinder-like structure; The axle at its two ends connects firmly on support arm through bearing block, it is characterized in that: described lifting shaft mechanism comprises lifting shaft, bearing and bearing block, connecting lever and support arm, also has fixed support; There is support arm at the lifting shaft two ends, and the middle part of lifting shaft also has a connecting lever hinged with the push action cylinder expansion link; Support arm on the lifting shaft and connecting lever are distributed on the excircle of lifting shaft, and lifting shaft mechanism is installed on the fixed support through lifting shaft two end axles bearing, and push action cylinder and bearing are hinged; Its beneficial effect is: during the push action cylinder reduction, and the rotation of pulling lifting shaft, lifting shaft drives free roller arrangement rotation; Two kinds of location of the non-holding state of horizontal level when realizing vertical support state or the flame cutting when free roller is in work, i.e. vertical the and horizontal level dibit function of free roller is when sending flexible dummy bar; Free roller is in vertical position, and the roller surface can adapt to the importing of flexible dummy bar, the requirement of derivation well for the transition supporting surface; Free roller can adapt to the requirement of the continuous cutting of flame cutting machine, flexible swinging well when level; Positioning accuracy is high, and is easy to maintenance.
