Abstract
The utility model discloses a guide at the inlet of a spring compressed type hot-rolling high-speed elliptical wire rolled piece, which comprises an inlet guide plate, a guide box, two idler pulleys and two supporting arms. One end of each supporting arm is fixedly connected to the inner wall of the guide box, and the other end thereof is connected with a corresponding guide wheel axle; and a spring is arranged between each supporting arm and the inner wall of the guide box. The guide has high adjusting accuracy, can not only prolong the service life of the guide, reduce the loss and the replacement frequency of the guide, and reduce steel-heaping accidents, but also reduce the scratch of the rolled piece and quality accidents caused by roller misplacement, thereby conducing to the improvement on the rate of certified products.
Description
Technical field
The utility model belongs to the rolling field of metal, relates in particular to aligning, guiding and the positioner of the oval wire rod rolled piece of a kind of spring compression type hot rolling high speed.
Background technology
Design of section of rolling mill generally adopts ellipse-circular hole system in metal rolled thick of rod, wire rod, is horizontal ellipse when rolled piece goes out oval groove, promptly transverse in the horizontal direction, minor axis is in vertical direction, vertical guide roll is adopted in the import guide and guard.The disclosed inlet rolling guide device of China utility model patent ZL90221718.6 is by guide cage, is contained in inlet guide and roller frame on the guide cage, and roller is contained on the roller frame.The major axis of elliptical rolled piece should enter circular hole with plumbness in theory, but in actual production process, for reducing heap steel accident or the guide and guard wearing and tearing that workpiece front end distortion and distortion cause, the capital increases guide plate, deflector roll opening degree, this must influence clamping and the centralizing function of guide and guard to rolled piece, and rolled piece often enters guide and guard with heeling condition.Its defective is that the inclination rolled piece impacts deflector roll, and deflector roll, bearing are easily broken, damage guide and guard, change frequently, also can cause heap steel accident; The tendency rolled piece is returned axial reaction force of top and bottom rolls, and continuous action can make the roll dislocation, and the rolled piece section is not round, causes the quality of lot accident; The effect of inertia of upset rolled piece can continue to influence the rolling stability of postorder sortie, and when rolled piece entered follow-up level or upright kink, distortion, scratch also damaged the guide and guard of postorder easily easily.The disclosed a kind of hot-rolled elliptical rolled piece inlet rolling guide of Chinese patent, publication number CN12345678, it comprises casing, establish the guide plate that has the rolled piece passage in the casing, casing is established cooling nozzle, and guide roller axis is established axis hole and is connected with oil nozzle, is characterized in being provided with at least on the casing deflector roll that a pair of axis crosses one another, the deflector roll that has the cambered surface pass in two stretches in the rolled piece passage obliquely, constitutes the sub-elliptical pass.Guide and guard are designed to be with the support arm form, guide roller axis can be designed to eccentric shaft, can be designed to the d-axis form again, eccentric guide roller axis upper end evenly is provided with the locating hole of adjusting two deflector roll roll spacings, by bolt guide roller axis is fixed on the sloping platform, select different locating holes, spacing that just can two deflector rolls of online adjustment is to adapt to the rolled piece of different size.
During use, casing is fixed on circular hole or square groove frame rear portion, when elliptical rolled piece passes the sub-elliptical pass that is made of deflector roll, the left side deflector roll gives its dextrad active force, the deflector roll that rolls to rolled piece align, clamping and correction, make its major axis enter circular hole, be rolled smoothly with plumbness.Its shortcoming is: because elliptical rolled piece is in the rolling instability of circular hole, must accurately adjusts rolling guide and come clamping, but that this technology accomplishes accurately to adjust rolling guide is very difficult, often occur elliptical rolled piece in circular hole because of incorrect rolling generation the " ears or side handles of a utensil ".
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of high oval wire rod rolled piece inlet of spring compression type hot rolling high speed guide and guard of accuracy of adjusting.
The utility model is achieved through the following technical solutions: the guide and guard of the oval wire rod rolled piece inlet of spring compression type hot rolling high speed, an end that comprises inlet guide, guide and guard box, two guide wheels, two support arms, described each support arm is fixed on the inwall of guide and guard box, the other end is connected with corresponding guide wheel shaft, is provided with spring between the inwall of described each support arm and guide and guard box.
One end of described spring is fixed on the support arm, the inwall of the other end and guide and guard box is with being threaded, and comes the elastic force of regulating spring by screw thread.
The periphery of described guide wheel is a concaved circular cambered surface.
During use, when elliptical rolled piece passes the sub-elliptical pass that is made of guide wheel, by the chucking power of spring, the guide wheel of rolling and support arm to the oval wire rod rolled piece of hot rolling high speed align, clamping and correction, make its major axis with level enter circular hole or, be rolled smoothly.Come the elastic force of regulating spring and length to adapt to the rolled piece of different size by screw thread.
The utility model has the advantages that, novel, simple and reasonable for structure, can reduce rolled piece distortion and crooked during use, reduce the impact of rolled piece, prolongation guide and guard service life deflector roll, bearing, reduce the guide and guard loss and change the frequency, reduce heap steel accident, help steel rolling production; Reduce the quality accident that the dislocation of rolled piece scratch and roll causes, help improving the product percentage of A-class goods.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Label declaration among the figure: 1, inlet guide, 2, the guide and guard box, 3, guide wheel, 4, support arm, 5, guide wheel shaft, 6, spring.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but do not constitute restriction of the present utility model.The guide and guard of the oval wire rod rolled piece inlet of a kind of spring compression type hot rolling high speed, an end that comprises inlet guide 1, guide and guard box 2, two guide wheels 3, two support arms 4, described each support arm 4 is fixed on the inwall of guide and guard box 2, the other end is connected with corresponding guide wheel shaft 5, between the inwall of described each support arm 4 and guide and guard box 2, a spring 6 is set, one end of described spring 6 is fixed on the support arm 4, the inwall of the other end and guide and guard box 2 is with being threaded, can come the elastic force and the length of regulating spring 6 by screw thread, described guide wheel 3 is recessed semi circular surface.
During use, when elliptical rolled piece passed the sub-elliptical pass that is made of guide wheel 3, by the chucking power of spring 6, the oval wire rod rolled piece of 3 pairs of hot rolling high speeds of the guide wheel of rolling was aligned, clamping and correction, make its major axis enter circular hole, be rolled smoothly with level.The length of coming regulating spring 6 by screw thread is to adapt to the rolled piece of different size.
The utility model has the advantages that, novel, simple and reasonable for structure, can during use Reduce rolled piece distortion and crooked, reduce rolled piece to the impact of deflector roll, bearing, prolong guide and guard and use Life-span reduces the guide and guard loss and changes the frequency, reduces heap steel accident, is conducive to steel rolling production; Reduce the quality accident that the dislocation of rolled piece scratch and roll causes, be conducive to improve the product percentage of A-class goods.
