Description
Technical field
The present invention relates to a kind of PM hydraulic press for powder metallurgy workpieces compacting.
Background technology
In the prior art, many powder metallurgy workpieces are completed by the compacting of hydraulic press, and powder metallurgy workpieces exist
Before being pressed shaping, its raw material is powder shaped, and it is to carry out at high operating temperatures to suppress work, that is, is molded when suppressing work
Upper mould and the lower mould of shaping are intended to be heated at high temperature.So when workpiece is pressed shaping, shaping upper leave the lower mould of shaping into
During pattern chamber, between the bottom end face meeting of shaping upper and workpiece surface produce material high temperature adhesion, cause workpiece surface by
Damage, workpiece quality are poor；If shield is pre-placed in the shaping mold cavity of mould to separate workpiece under shaping before workpiece compacting
Contact with shaping upper, but the shield being pre-placed can make the powder metallurgy powder in shaping mold cavity when falling in shaping mold cavity
Material produces dust raising phenomenon, and destruction work environment simultaneously has a strong impact on workers ' health.
The content of the invention
In view of the deficiencies in the prior art, the technical problem to be solved in the present invention is to be that providing one kind is used for powder metallurgy work
The compacting of part, sizing was not only prevented but also had prevented airborne dust, and improved efficiency and more preferably ensure the PM hydraulic press of workpiece quality.
The present invention is adopted the following technical scheme that to complete：
PM hydraulic press, including top plate, bottom plate, intermediate plate and column, top plate, bottom plate are fixedly connected by column, middle
Plate is promoted the lifting action for making above-below direction in the lower section of top plate by master cylinder, and master cylinder is installed on top plate, the bottom of intermediate plate
Shaping upper is fixedly mounted in portion surface, and the lower mould of shaping is fixedly mounted in the top surface of bottom plate, and molding bottom die has what is be inwardly recessed
Shaping mold cavity, shaping upper enters shaping mold cavity when suppressing work, it is characterised in that：The bottom end face of shaping upper is provided with upper
Simultaneously high temperature resistant magnet is fixedly mounted in steel plate, upper steel plate by high temperature resistant magnet magnetic absorption shaping upper bottom end face；When
When shaping upper leaves shaping mold cavity after the completion of workpiece compacting, the magnetic adsorptive power between upper steel plate and high temperature resistant magnet is less than
Adhesion between upper steel plate and workpiece.
The bottom of chamber of shaping mold cavity is movably equipped with lower steel plate and liftout plate, and liftout plate is located at the lower section of lower steel plate, liftout plate
Bottom connects push rod, and push rod is moved up and down by lower oil cylinder pushing.
Using the PM hydraulic press of above-mentioned technical proposal, when carrying out powder metallurgy workpieces compacting not only prevented sizing but also
Airborne dust is prevented, concrete operating principle is：The bottom end face of shaping upper has upper steel plate by high temperature resistant magnet magnetic absorption, so
One, when workpiece is pressed shaping, shaping upper leaves the shaping mold cavity of the lower mould of shaping, the bottom end face and work of shaping upper
Will not produce material adhesion between part surface, workpiece surface only produces material adhesion between upper steel plate, but due to upper steel plate with
Magnetic adsorptive power between high temperature resistant magnet is less than the adhesion between upper steel plate and workpiece, so being left into shaping upper
Under type during the shaping mold cavity of mould, upper steel plate does not move upwardly together with shaping upper and is to continue with staying in surface and the work of workpiece
Part is sticked together, and only after workpiece cools down completely, then upper steel plate is moved away from into workpiece surface, but now because workpiece is complete
Full cooling and shaping, so being moved away from for upper steel plate will not cause to damage to workpiece surface, so as to more preferably ensure workpiece quality.Above-mentioned mistake
Cheng Zhong, because powder can not avoided toward shield is pre-placed to separate contact of the workpiece with shaping upper in shaping mold cavity
The generation of the dust raising phenomenon of last metallurgy powder, and then keep working environment clean and tidy, reduce the influence to workers ' health.
Brief description of the drawings
The present invention has drawings described below：
Fig. 1 is the structural representation of PM hydraulic press.
Embodiment
As illustrated, the PM hydraulic press of the present invention, including top plate 2, bottom plate 8, intermediate plate 3 and column 7, top plate 2,
Bottom plate 8 is fixedly connected by column 7, and intermediate plate 3 is promoted the lifting action for making above-below direction in the lower section of top plate 2 by master cylinder 1,
Master cylinder 1 is installed on top plate 2, and shaping upper 4 is fixedly mounted in the lower surface of intermediate plate 3, and the top surface of bottom plate 8 fixes peace
Mould 9 under type are dressed up, being molded lower mould 9 has the shaping mold cavity 91 being inwardly recessed, and shaping upper 4 enters shaping mould when suppressing work
Chamber 91, the bottom end face of shaping upper 4 are provided with upper steel plate 6 and high temperature resistant magnet 5 are fixedly mounted, and upper steel plate 6 passes through high temperature resistant magnetic
Bottom end face of the magnetic absorption of iron 5 in shaping upper 4；When shaping upper 4 leaves shaping mold cavity 91 after the completion of workpiece compacting, on
Magnetic adsorptive power between steel plate 6 and high temperature resistant magnet 5 is less than the adhesion between upper steel plate 6 and workpiece.Shaping mold cavity 91
Bottom of chamber be movably equipped with lower steel plate 10 and liftout plate 11, liftout plate 11 is located at the lower section of lower steel plate 10, and the bottom of liftout plate 11 connects
Push rod 12 is connect, push rod 12 is promoted by lower oil cylinder 13 and moved up and down.
The present invention so works：The bottom end face of shaping upper 4 has upper steel plate by the magnetic absorption of high temperature resistant magnet 5
6, so, when workpiece is pressed shaping, shaping upper 4 leaves the shaping mold cavity 91 of the lower mould 9 of shaping, shaping upper 4
Material adhesion will not be produced between bottom end face and workpiece surface, workpiece surface only produces material adhesion between upper steel plate 6, but
Because the magnetic adsorptive power between upper steel plate 6 and high temperature resistant magnet 5 is less than the adhesion between upper steel plate 6 and workpiece, so
Shaping upper 4 leave shaping under mould 9 shaping mold cavity 91 when, upper steel plate 6 do not moved upwardly together with shaping upper 4 but
The surface for continuing to stay in workpiece is sticked together with workpiece；Then, lower oil cylinder 13 is acted, and liftout plate is pushed up by push rod 12
11, workpiece and upper steel plate 6, lower steel plate 10 are released shaping mold cavity 91 by liftout plate 11 simultaneously, after workpiece cools down completely, then will
Upper and lower steel plate is moved away from workpiece surface, but now due to workpiece complete cooling and shaping, so being moved away from for upper and lower steel plate will not
Workpiece surface is caused to damage, more preferably ensures workpiece quality.
