Abstract
The invention discloses an automatically displaceable lower anvil, belonging to the technical field of the forging application of the hydraulic press. A shifting device is arranged on the lower end of the lower anvil, which is composed of a connection frame and a plurality of rollers, wherein the plurality of rollers are arranged in the connection frame and the shaft heads of the two ends of each roller are connected in the connection frame in a sliding manner. The lower anvil and the shifting device move with respect to each other. The shifting device is arranged on the material feeding table of the hydraulic press. A steel ingot blank is arranged on the lower anvil. When the hydraulic press is forging a steel ingot, the steel ingot on the lower ingot blank is stressed to generate a transverse load which may move the lower anvil along the rollers. So that the transverse load generated on the upright of the hydraulic press is eliminated along with the displacement of the rollers under the lower anvil. The surface quality of the steel ingot can be improved and the surface cracks of the steel ingot can be reduced; and the risk of plastic deformation or even damage of the movable cross beam and the upright of the hydraulic press is reduced or eliminated; therefore, the service life of the hydraulic press is prolonged.
Description
Technical field
The present invention relates to anvil under a kind of displacement automatically, belong to the dydraulic forging applied technical field.
Background technology
At present, the steel ingot that forge in the flat-die forging field more and more tends to large-scale, large, and the steel ingot of forging large-size forge piece is promoted to 600 tonnes by 200 tonnes of the past.These large-scale steel ingots still in various degree have porosity defectives such as shrinkage cavity, loose, pore, reach the country of destination of steel ingot compacting for the defective of seam steel ingot inside and outside heavy forging manufacturer constantly researched and developed many forging methods, and be successfully applied to production.Having many in these methods is special forging methods of asymmetrical deformation, asymmetrical deformation makes the required press pressure minimum of steel ingot heart portion compacting than other forging method under the same conditions because of it, consolidation effect is best, therefore the pulling method of forging the FM of employing in the large-scale steel ingot pulling more.Various forging methods equal having plastic deformation that asymmetrical deformation load and symmetric deformation produce and causing non-symmetrical load in various degree in actual production by it, and the transverse load maximum of the press that produces by asymmetrical deformation, be approximately 1/5 of press pressure, such transverse load is enough to cause that the resilient bias amount appears in the press rigid structure.And at present in all known forging methods all following anvil designs all be fixed, can't eliminate or reduce the adverse effect of these transverse loads to hydraulic press.In the forging process of large-scale steel ingot through regular meeting hear the huge noise of press, experience press vibrations, can see rocking of press, even the case of the damage of hydraulic press column and moved cross beam appears.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the invention provides anvil under a kind of displacement automatically.This consolidation effect that anvil can not only satisfy steel ingot heart portion under displacement automatically also can alleviate or eliminate lateral load to be damaged hydraulic press.
The present invention solves the technical scheme that its technical barrier adopts: following anvil lower end is provided with displacement device, and displacement device is made up of connection box and several roller bearings, is provided with several roller bearings in the connection box, and the spindle nose at roller bearing two ends is slidingly connected in the connection box.
Following anvil and displacement device move mutually, and what displacement device was arranged on hydraulic press walks to expect that on the platform, the steel ingot blank is placed on down on the anvil.
When hydraulic press forging steel ingot, after the steel ingot on the following anvil was stressed, the transverse load of generation can will play anvil to move along roller bearing, and the transverse load that produces on the hydraulic press column is eliminated with the displacement of the roller bearing under the following anvil.
The invention has the beneficial effects as follows: automatically under the displacement anvil hydraulic press walk to expect that variable bit moves on the platform, can realize effective compacting of ultra-large type steel ingot heart defect, can improve the surface quality of steel ingot, reduce the generation of surface of steel ingot crackle; The transverse load that hydraulic press is produced converts anvil displacement displacement force under the displacement automatically to, make anvil under the displacement automatically form relative displacement with hydraulic press, reduction or elimination prolong the service life of hydraulic press to the danger of hydraulic press moved cross beam and column generation plastic deformation and then damage.
Description of drawings
Fig. 1 is that anvil uses schematic diagram under the roller of the present invention.
Fig. 2 is an anvil structural representation under the roller of the present invention.
Fig. 3 is that anvil is looked up structural representation under the roller of the present invention.
Among the figure 1, connection box, 2, roller bearing, 3, anvil down, 4, the steel ingot blank, 5, the hydraulic press moved cross beam, 6, the hydraulic press column, 7, walk to expect platform.
The specific embodiment
As shown in Figure 1-Figure 3, following anvil 3 lower ends are provided with displacement device, and displacement device is made up of connection box 1 and several roller bearings 2, is provided with several roller bearings 2 in the connection box 1, and the spindle nose at roller bearing 2 two ends is slidingly connected in the connection box 1.
Following anvil 3 moves mutually with displacement device, and what displacement device was arranged on hydraulic press walks to expect that on the platform 7, steel ingot blank 4 is placed on down on the anvil 3.
When hydraulic press 5 forging steel ingots 4, after steel ingot on the following anvil 34 was stressed, the transverse load of generation can will play anvil 3 to move along roller bearing 2, and the transverse load that produces on the hydraulic press column 6 is eliminated with the displacement of the roller bearing 2 under the anvil 3 down.
