The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
In the band shear history, prior art adopts the band after guide plate directly will be cut to be sent on the belt feeder.This patent provides a kind of anti-scratch buffering transition apparatus, and with reference to Fig. 2, innovative point is, between the cutting edge of moderate shear machine and delivery guide guide wheel 1 is set, and described guide wheel 1 is fixed on the frame of moderate shear machine.
Guide wheel is arranged at the position between cutting edge and the delivery guide, when mounted, make the upper surface height of living in of guide wheel 1 be higher than delivery guide 12 by cutting edge one end, like this, the band that comes out from cutter at first contacts guide wheel 1, replace sliding friction between original band and the delivery guide with the rolling friction of guide wheel, thereby avoid band to be scratched.
In order to strengthen buffering transiting performance of the present utility model, above foundation structure is proceeded following improvement:
Described guide wheel 1 is fixed on the spring assembly top, and described spring assembly is fixed on the frame.Utilize the shock-absorbing capacity of spring assembly, can effectively alleviate band and cut moment, its tail end obtains the acceleration of moment, thereby makes band be smoothly transitted into delivery guide 12.
Described spring assembly comprises:
Pass the wheel shaft 5 that the guide wheel centre bore is used for supporting wheel 1;
The axle stand 3 that is used for fixing wheel shaft 5;
Be arranged on the spring 2 of axle stand 3 belows in order to the support axle stand.
Described axle stand 3 is fixed on the cramp bar 4, and cramp bar 4 vertically passes the through hole of guide cylinder 7 bottoms; Cramp bar 4 is provided with external screw thread and is connected with adjusting nut 6, and described adjusting nut 6 is arranged on the guide cylinder below; Described spring 2 is socketed on the cramp bar 4 between guide cylinder 7 and the axle stand 3.
Described guide cylinder 7 is fixed on the frame.
In order to increase shock-absorbing capacity better, above foundation structure is proceeded following improvement:
Described guide wheel 1 is the line with rubber wheel.
Advantages such as flexible good, the wear-resistant and absorbing of line with rubber wheel is moving are used the pressure spot of line with rubber wheel as buffer unit, and the momentary action power that produces in the time of can effectively cushioning band and cut again because of its good springiness, can not cause scuffing to strip surface.
Below, in conjunction with Fig. 2, Fig. 3 and Fig. 4, provide the operating position of the utility model in practice, and be described further:
The Cutronic high speed cross cut shears of Germany Ungerer company was introduced and is used by the cold-strip steel of the many large-scale iron and steel enterprises of China unit of working continuously in the nineties in last century.Wuhan Iron and Steel Plant has been introduced two from Ungerer company in the early 1990s, is installed in a cold rolling mill finishing workshop, claims the Weng Geer flying shear.In recent years, along with the development of Wuhan Iron and Steel Plant, various new steel grades are disconnected to put into production, and market is more and more higher to the requirement of plate surface quality, and the market competitiveness improves for adapting to market demand in Wuhan Iron and Steel Plant joint-stock company, has proposed plate surface quality " zero failure " delivery.But producing thickness of slab is No. 2 horizontal product bottom surfaces of cutting production line of 1.0mm～1.5mm specification, is often produced faint cut by parts around the flying shear, causes this production line to be in half end-of-life state substantially.
Fig. 1 is an arrangement of mechanism sketch before and after the prior art flying shear.As shown in the figure, in flying shear when work,, the band steel pinched inlet transition guide plate platform 9-after six-roller straightener 8 is just rectified〉haul out roller 10-〉flying shear transition guide plate 11, by flying shear, arrive delivery guide 12, carry out the transition on the belt feeder 13 through delivery guide 12 and transport.Flying shear when work, by being installed on the flying shear, and move with flying shear, cutter beam transition guide plate 14 is held and is finished shearing, by belt feeder 13 active transport to next operation.
In the prior art, when producing the band steel of 1.0mm thickness, taking the lead needs to smoothly transit on the belt feeder through flying shear delivery guide 12.In actual shear history, finish the moment of shearing when flying shear, band steel tail end speed after being sheared is in theory from the 0 instantaneous 150m/min that accelerates to, and gravitate, fall fast on the delivery guide 12, produce relative force of sliding friction with delivery guide 12, this active force is easy to make every block plate tail end of shearing after finishing to produce and scratches.
As shown in Figure 2, between the delivery guide 12 of original flying shear mechanism and flying shear blade guide wheel 1 is set, band steel toe portion is through the guide wheel of buffer unit, and even deceleration is fallen on the belt feeder 13, owing to there is guide wheel 1 to hold, does not contact with delivery guide 12; After the shearing, band steel tail end is through behind the spring buffer, and even deceleration is fallen on the delivery guide 12, this moment, strip speed was basic and belt feeder 13 is synchronous, it is very little that frictional force has been reduced to, and adjusting nut can give tight power according to the thickness of slab regulating spring, and the band steel is fallen on the delivery guide 12 with desirable even geard-down speed.
By anti-scratch buffering transitional function of the present utility model, make the active force of band steel after being cut obtain good alleviation, eliminated the band steel and caused the steel plate tail end of shearing after finishing to produce the problem of scuffing with the big relative force of sliding friction of delivery guide generation.
The utility model not only can be used respectively according to on-site actual situations at the continuous processing line of metallurgy industry hot-rolled and cold-rolled band, and needs the industry of anti-scratch that higher value for applications is also arranged at non-ferrous metal, papermaking etc.
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.Need to prove in addition; above-mentioned embodiment just to the exemplary illustration of this patent and and non-limiting its protection domain; those skilled in the art can make some local changes to this patent, so long as just available without creative work, all within the protection domain of this patent.
