The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
The explanation of mark among Fig. 1: guiding leaf spring 1, extension spring 2, fixed mount 3, vibrating grid 4, bracing frame 5, transition frame 6, hydraulic cylinder 7, pull bar 8, protective plate 9, casting machine horizontal center line L1, casting machine datum line L2.
The explanation of mark among Fig. 3: crystallizer 10, fixing point A, C, D, F, oscillation point B, E, guiding leaf spring centre of support line L3, center of gravity vertical line L4 such as vibrating grid and crystallizer.
The structure of the embodiment of the invention is referring to Fig. 1 and Fig. 2.
Square billet, circle base and shaped blank hydraulic vibration device comprise guiding leaf spring 1, extension spring 2, fixed mount 3, vibrating grid 4, crystallizer brace table 5, transition frame 6, hydraulic cylinder 7, pull bar 8 and protective plate 9; Crystallizer brace table 5 is used to support crystallizer 10, and crystallizer brace table 5 is put into fixed mount 3 from top to bottom, links to each other with vibrating grid 4 by bolt; Vibrating grid 4 is packed into by fixed mount 3 one sides, and the overlapping region of enough installation leaf spring width is overlooked in vibrating grid 4 and fixed mount 3 both sides, constructs the space that the guiding leaf spring is installed; Vibrating grid 4 front ends link to each other with shackle rod 8, are the power resources of vibration; It is characterized in that: fixed mount 3 is provided with eight fixing points, and every side four fixing point A, C, D, F link to each other with every group of guiding leaf spring 1 two ends fixing point respectively; Vibrating grid 4 is provided with four and is used for connecting guiding position, leaf spring 1 oscillation point, every side two oscillation point B, E, as shown in Figure 2, totally four groups, every side arrangement principle is followed leaf spring center extended line by the casting machine center O, and four fixing point A, D, C, F and two oscillation point B, the E of four vibration guiding leaf springs 1 on three isocentric circular arc, constitute the imitative arc motion of the common structure of guiding leaf spring system respectively; Vibrating grid 4 legacy devices of being different from over, its traverses fixed frame, oscillation point B, the E with the left and right sides links into an integrated entity rigidly, avoids over both sides leaf spring independent stationary, but produces the possibility of rocking because of processing or alignment error; Guiding leaf spring 1 fixing point A, D, C, F are positioned at oscillation point B, E both sides, overcome the deficiency that past vibrating grid and the relative guidance system of crystallizer center of gravity vertical line centre of support line are in cantilever position, make it to be positioned at same cross section, see Fig. 3.
Guiding leaf spring system (constituting) by four groups of guiding leaf springs 1, realize that vibrating grid 4 and bracing frame 5 move around the imitative arc of conticaster centre of oscillation O work with respect to fixed mount 3, this center O also is the instantaneous centre of guiding leaf spring system, and the imitative arc radius size of casting machine depends on technological requirement; Oscillation point B, the E of guiding leaf spring 1 are rigidly connected by vibrating grid 4, and fixing point A, C, D, the F of guiding leaf spring 1 end are rigidly connected with fixed mount 3 respectively, and the imitative arc system of common structure vibration is as Fig. 3; And traditional vibrational system of past, guiding leaf spring system places the vibrating device both sides, and the frame 3 that is fixed separates it, form separate, vibrate center of gravity L4 such as vibration that guidance system supports and crystallizer simultaneously outside guiding leaf spring centre of support line L3, be in cantilever position, as Fig. 4.
Each two groups guiding leaf springs 1 about lay in the space of building by fixed mount 3 and vibrating grid 4 laps in the present embodiment; because overlapping energy protection guiding leaf spring 1; having added protective plate 9 is covering; guiding leaf spring 1 will be in the good working environment, avoids being subjected to the infringement of bleed-out, ambient water steam and greasy dirt.
In the present embodiment, also have the extension spring system between vibrating grid 4 and the fixed mount 3, be made of two groups of extension springs 2, vibrating grid 4 rear ends link to each other with extension spring 2, and extension spring 2 is born and overcome the side load task, is the assurance that overcomes side force, ensure that the amount of deflecting satisfies technological requirement; Reduce the cross force that may impose on pull bar 8 simultaneously as far as possible.The axial force of 8 transmission fluid cylinder pressures of pull bar, and the cross force that load may not occur returns to hydraulic cylinder 7 is guaranteed 7 service lifes of hydraulic cylinder.Hydraulic cylinder 7 is contained in the metal seal box, guarantees that hydraulic cylinder 7 inner all elements are in good working environment.
In the present embodiment, fixed mount 3 is not directly to be contained on the on-the-spot steel construction piece, but is contained on the transition frame 6, and this gives and guarantees installation accuracy, for convenience detach providing convenience.Protective plate 9 is equipped with in vibrating grid 4 and fixed mount 3 sides, protection guiding leaf spring 1.Drip tray, hydraulic oil pipe and cable all have snap joint, convenient loading and unloading fast.
Operation principle of the present invention remains the imitative arc motion of traditional galianconism four connecting rods, and promptly the extended line at two guiding leaf spring centers should meet at the center of conticaster arc, and this point also is the instantaneous centre of four link motions; Four fixing point A, D, C, F and two oscillation point B, the E of four guiding leaf springs 1 are on three isocentric circular arc, as shown in Figure 3.Vibrating grid 4 is realized by hydraulic cylinder 7 and pull bar 8 with respect to the motion of fixed mount 3.Be to improve the stable working of device, strengthen its opposing side loading ability, set up extension spring 2, not only make vibration steadily, make transmission device hydraulic cylinder 7 not be subjected to cross force, and buffering hydraulic cylinder 7 power that withstands shocks.
