Abstract
The invention discloses a coned workpiece stretching die. The coned workpiece stretching die comprises an upper die plate, a material ramming disc, female dies, guide sleeves, guide pillars, blank holders, a male die, a male die fixing plate and a lower die plate. The female dies and the material ramming disc are installed below the upper die plate through pins and screws; the guide sleeves are fixed below the upper die plate; the guide pillars are fixed above the lower die plate and are in relative sliding fit with the guide sleeves; the male fixing plate is fixed above the lower die plate through pins and screws and the male die is connected above the male die fixing plate, and is sleeved with the blank holders. The coned workpiece stretching die can ensure that blank holder force is even and stable in the production process.
Description
Technical field
The present invention relates to a kind of mechanical workpieces production, relate in particular to a kind of cone workpiece drawing die.
Background technology
Stretching is of paramount importance technique in cone workpiece manufacture process, determined the quality of Workpiece shaping quality, at present, the flow field problem that improves material has become the important process content of designing and making drawing die, and our factory, in the draw stage of cone workpiece, adopts mould and the technique of existing structure, there will be the pressure-pad-force skewness acted on blank holder, the problem that pressure-pad-force is stable not, easily cause workpiece obvious concavo-convex vestige to occur, and smoothness is low.
Summary of the invention
The problems referred to above that exist for solving prior art, the present invention has improved cone workpiece drawing die structure, with reasonability and the stability that increases monolateral gap, has solved the problem of pressure-pad-force skewness.
The present invention adopts following technical scheme:
A kind of cone workpiece drawing die, comprise cope match-plate pattern, dnockout dish, die, guide pin bushing, guide pillar, blank holder, punch, punch retainer, lower bolster;
Die and dnockout dish are installed on the below of cope match-plate pattern by pin and screw, guide pin bushing is fixed in the below of described cope match-plate pattern, and guide pillar is fixed in the top of lower bolster, and described guide pillar coordinates with described guide pin bushing relative sliding;
Punch retainer is fixed in the top of lower bolster by pin and screw, its top connects punch, and the outside of described punch is set with the blank holder of annular;
The inner guiding post below that be installed on blank holder parallel with ejector beam, the guide hole on described inner guiding post and punch retainer coaxially slides, and described ejector beam is connected with the square chest of its below with lower bolster through described punch retainer successively.
The material selection microalloy Cr12MoV mould steel of cone workpiece drawing die, the Technology for Heating Processing of mould steel is: after hot rolling, be heated to 1050 ?1150 ℃ carry out solution treatment, be as cold as soon 600 ℃ proceed to 400 ?make it isothermal transformation in 700 ℃ of stoves, after machined, be heated to 900 ?950 ℃ of oil quenchings, finally 150 ?200 ℃ of tempering.
Each individual components that forms described cone workpiece drawing die adopts Digit Control Machine Tool processing.
The invention has the beneficial effects as follows: the material selection microalloy Cr12MoV mould steel of punch and die, guaranteed die hardness, mould steel adopts above-mentioned Technology for Heating Processing, has reduced carbon emission, and quenching degree can be enhanced about more than once; The independent workpiece of Digit Control Machine Tool processing mold, improved the precision of independent workpiece; Be provided with four groups of inner guiding posts, improved the stability in monolateral gap; Independent workpiece high accuracy processing and overall construction design optimization, reasonability and the stability in the monolateral gap of the present invention have been improved, the gap of punch and die is remained between 0.01-0.02mm, adopt above technical scheme, can make pressure-pad-force be evenly distributed, and comparatively stable, improved the surface flatness of producing workpiece, simultaneously, completed the stretch process of cone workpiece.
The accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the top view of lower bolster.
