The specific embodiment
This reality has novel rolling high-speed line, bar rolling guide apparatus, and it comprises guide groove 1, cover plate 2, base 3, rotational pin 4, it is characterized in that: further comprising guide wheel pair 5, guide wheel shaft 6, bearing 7; Have a groove in the rear end of guide groove 1, groove each side be provided with a guide wheel pair 5, guide wheel pair 5 is fixed on the guide groove 1 by guide wheel shaft 6, bearing 7.
Wherein, guide groove 1 not only plays the effect of parent, and can also play at work the effect in the U type pass of rolled piece 13 smooth introducing guide wheel pairs.Guide groove 1 adopts the QT material, has guaranteed that it is wear-resisting and as the on-deformable requirement of parent.Cover plate 2 is provided with boss and oblique horn mouth, the effect that has played the accurate location between cover plate 2 and the guide groove 1 respectively and induced rolled piece to enter.The material of guide wheel pair 5 is Cr13WMoV, and hardness is HRC55-58.Formed the U type pass that meets workpiece measurement and the ample clearance is arranged between two guide wheel pairs 5, two deep groove ball bearings 7 are installed in the working face upper end between guide wheel secondary 5 and the guide wheel shaft 6, and a deep groove ball bearing 7 is installed in the lower end; Thereby guaranteed rolled piece 13 by the time form rolling friction between rolled piece 13 and the guide wheel pair 5, guaranteed the wearability of guide wheel pair 5 and the stability when rotating at a high speed.
As this novel a kind of optimal way, this device also comprises separator 8, oil gas mouth 9; Guide wheel shaft 6 is processed with a hole along the center, the bottom, hole links to each other with oil gas mouth 9 by internal thread, and top, hole is processed with perpendicular crossing cross through hole, and the cross through hole place is provided with separator 8, and separator 8 is between metal (upper 7.Like this, formed oil gas lubricating system at oil gas mouth 9, guide wheel shaft 6, separator 8.High-pressure oil gas enters from oil gas mouth 9, the perpendicular traversed by entry of guide wheel shaft 6 of flowing through arrives separator 8, distribution by separator 8, the hydraulic oil cyclone is wrapped in outside the bearing 7 of rotation at a high speed, lubricating oil is sprayed in the bearing 7, not only bearing 7 is lubricated, cooling water and dirty entering in the bearing 7 have also been stoped, reduce the temperature of bearing 7 simultaneously, making its dm.n value can reach 1500000(is 3 times of dry oil lubrication), guaranteed the ordinary life that bearing 7 uses.
As this novel another kind of optimal way, it also comprises water nozzle 10, sealing ring 11; The center of opening shelves at base 3 is provided with a through hole, links to each other with water nozzle 10 by pipe joint; On the guide groove 1 perpendicular to the horizontal water hole of guide wheel shaft 6 through being parallel to the perpendicular water hole of guide wheel shaft 6, link to each other with through hole on the base 3; Sealing ring 11 is arranged on the contact-making surface of base 3 and guide groove 1.In guide groove 1 is aimed at the opening that guide wheel pair 5 is installed, be provided with the horizontal water hole of 6 3.5mm diameters and the perpendicular water hole of 2 6mm diameters, they with base 3 on screw, sealing ring 11, and water nozzle 10 composition cooling water systems.Cooling water is with 4.5Mp/cm
2Pressure reaches perpendicular water hole, horizontal water hole on the guide groove 1 by water nozzle 10 base 3 through holes of flowing through, and sprays to guide wheel secondary 5 and rolled piece 13.Cooling water has not only reduced the temperature of guide wheel pair 5, and produces one deck steam blanket on the rolled piece surface of nearly thousand degree high temperature, has reduced the friction of rolled piece 13 with guide wheel pair 5, the service life of having improved guide wheel pair 5.
As this another novel optimal way, it also comprises contiguous block 12; Contiguous block 12 is fixedlyed connected base 3 with guide groove 1.Thereby prevent that base 3 produces relative motion with guide groove 1 when rolled piece 13 passes through.
This device can be according to the different product specification of high-speed line, rolling bar, and promptly the different size of rolled piece when recovering section made amendment to the relative dimensions that constitutes pass on guide groove 1, cover plate 2, the guide wheel pair 5, just can satisfy instructions for use.In the time of after guide apparatus breaks down or weares and teares, can not using,, open cover plate, remove rolled piece, just can guide groove assembly or the replacing of other damaged parts as long as open fastening handle.The guide groove assembly generally assembles in the guide and guard assembly room in advance.
The utility model has solved in high-speed line, the rolling bar process problem that guide groove when using circuit to recover section scratches the rolled piece surface, thereby for product line, bar obtains the high-quality surface quality that guarantee is provided.This device also can be used for replacing the linear pattern after high-speed line, the bar finish rolling to recover sliding guide groove device on the section.Former sliding guide groove device and the price comparison of the utility model rolling guide apparatus: the former 629 yuan/cover, 969 yuan of the latter/cover, ratio: 1:1.54.But the latter on service life be the former more than 15 times.Therefore high-speed line, bar guide and guard cost reduce 90% approximately in this consumption.
