Abstract
The utility model discloses a high accuracy hydraulic press belongs to the hydraulic forming equipment field. Including guide post and the deflector that can follow the guide post operation, installing the uide bushing between guide post and the deflector, the uide bushing sets up the endotheca in the overcoat including fixed overcoat that sets up and activity, and the overcoat is wedge cooperation, endotheca along overcoat inboard inclined plane motion with the endotheca, interior ways is on the guide post, and the overcoat is fixed in the support, and the support is connected with the deflector through the bolt, and the deflector is equipped with the spring in impressing the endotheca in the overcoat between bolt and the deflector. Through the two mutual adaptation of endotheca of fixed overcoat and activity, guarantee that the endotheca can slide between overcoat and guide post, behind the medial surface and guide post wearing and tearing of endotheca, the endotheca interpolates into to the overcoat voluntarily under the effect of spring, avoids the influence that wearing and tearing led to the fact between guide post and the deflector to the shaping.
Description
Technical field
This utility model relates to a kind of hydraulic press, is especially a kind of high precision hydraulic press, belongs to hydraulic forming device field.
Background technology
Hydraulic press is a kind of with liquid as working media, according to pascal's principle make for transmitting energy to realize polytechnic machine.Existing hydraulic press can produce abrasion long-time to some extent, cause rocking in guide plate running, cause the deviation of the descending route of upper mold in punching course between guide plate and lead, finally affect the formed precision of workpiece.
Utility model content
Technical problem to be solved in the utility model is to overcome prior art defect, it is provided that one can slow down weares and teares between guide plate and lead, improves the hydraulic press of formed precision.
In order to solve above-mentioned technical problem, the high precision hydraulic press that this utility model provides, including lead and the guide plate that can run along lead, fairlead is installed between described lead and guide plate, described fairlead includes the overcoat being fixedly installed and the inner sleeve being movably set in overcoat, described overcoat is wedge shaped with inner sleeve to be coordinated, and inner sleeve is moved along overcoat medial slope；Described inner sleeve is enclosed within lead, and described overcoat is fixed in support, and described support is connected with guide plate by bolt, and inner sleeve is pressed in overcoat by described guide plate, is provided with spring between described bolt and guide plate.
In this utility model, the contact site of described guide plate, inner sleeve and lead is provided with elastic protective pad.
In this utility model, described elastic protective pad is rubber blanket.
In this utility model, the medial surface of described inner sleeve forms lubricant reservoir circumferentially arranged with a plurality of lubrication groove, described inner sleeve with the gap of overcoat wedge shape adaptation.
The beneficial effects of the utility model are: (1), the overcoat passing through to fix are mutually adapted with movable both inner sleeves, ensure that inner sleeve can be slided between overcoat and lead, after the medial surface of inner sleeve weares and teares with lead, inner sleeve advances automatically in overcoat under the action of the spring, it is to avoid the impact causing molding of wearing and tearing between lead and guide plate；(2), it is provided with elastic protective pad at the contact site of guide plate, inner sleeve and lead, the elasticity of inner sleeve can be improved, make three contact more closely reliable；(3), at the medial surface of inner sleeve circumferentially arranged with a plurality of lubrication groove, the inner sleeve gap adaptive with overcoat wedge shape forms lubricant reservoir, sustainable to providing lubrication between lead and guide plate, reduces abrasion.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model high precision hydraulic press；
Fig. 2 is guide sleeve structure schematic diagram；
Fig. 3 is inner sleeve structure chart.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As it is shown in figure 1, high precision hydraulic press of the present utility model, including base 1, upper mold 6, lower mold 7, added 2, hydraulic jack 4 and lead 3.Connecting lead 3 respectively between added 24 angles corresponding with base 1, rubber blanket 8 is laid in the bottom of base 1.Hydraulic jack 4 is arranged on added 2, is connected (not shown) with hydraulic system.The push-pull bar bottom connecting guide plate 5 of hydraulic jack 4,4 angle equal perforate correspondences of guide plate 5 are inserted on 4 leads 3, and the lower section of guide plate 5 connects upper mold 6, and hydraulic jack 4 drives upper mold about 6 to run by guide plate 5；Lower mold 7 is positioned at the underface of upper mold 6, is arranged on base 1.Being provided with fairlead 9 between each guide plate 5 and lead 3, fairlead 9 is enclosed within lead 3 and is connected with guide plate 5.
As in figure 2 it is shown, fairlead 9 includes support 9-3, overcoat 9-1 and inner sleeve 9-2, overcoat 9-1 and inner sleeve 9-2 are loop configuration.Support 9-3 is positioned at the lower section of guide plate 5, is connected with guide plate 5 by hold-down bolt 9-4.Overcoat 9-1 is fixed on inside support 9-3, between mounting bracket 9-3 and lead 3, it is ensured that its lateral surface fits tightly with support 9-3.Inner sleeve 9-2 is enclosed within lead 3, guide plate 5 is by inner sleeve 9-2 press-in overcoat 9-1, it is directed to plate 3 by hold-down bolt 9-44 fasten with mounting bracket 9-3, and at hold-down bolt 9-4 and guide plate 3 pocketed springs 9-5, persistently inner sleeve 9-2 is formed downforce, use inner sleeve 9-2 to keep laminating with lead 3 moment, use guide plate to run up and down along lead, it is to avoid to produce because of abrasion and rock.
Contact site between guide plate 5, inner sleeve 9-2 and lead 3 three is provided with rubber fender 9-6, by the elasticity of rubber fender 9-6, can improve the elasticity of inner sleeve 9-2, makes three contact more closely reliable.Using wedge-like engagement between overcoat 9-1 and inner sleeve 9-2, inner sleeve 9-2 can move downward along overcoat 9-1 medial slope.
As shown in Figures 2 and 3, the medial surface of inner sleeve 9-2 of the present utility model is circumferentially arranged with a plurality of lubrication groove 9-8, the gap formation lubricant reservoir 9-7 that inner sleeve 9-2 is adaptive with overcoat 9-1 wedge shape, lubricating oil in lubrication groove 9-8 can quickly arrive the inside of fairlead and store, so ensure that the sustainable supply of fairlead 9 internal lubrication oil, reduce fairlead 9, abrasion between guide plate 5 and lead 3.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
