Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the structural representation of the utility model embodiment 1;
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described:
Embodiment 1
As shown in Figure 1, a kind of mould bases used on the 63T Full Automatic Liquid press of repacking comprises cope match-plate pattern, negative template, middle template and lower bolster, press slide 1 is fixed with cope match-plate pattern 2, the two ends of cope match-plate pattern 2 are fixed with the two upper leads 3 stretched out downwards, the bottom surface central authorities of cope match-plate pattern 2 are fixed with pressure pad 4, the central authorities of upper pressure pad 4 are fixed with the upper press cover 5 stretched out downwards, and the central authorities of upper press cover are fixed with the upper punch 6 stretched out downwards;
The mid portion of two upper leads 3 is provided with negative template 7, and negative template 7 is set on upper guide post 3 and also can moves up and down along upper guide post 3, and negative template 7 upper surface is fixed with powder feeding plate 8, powder feeding plate 8 is fixed with dust feeder 9; The central authorities of negative template 7 are provided with the former 10 of the strip stretched out downwards, and former 10 is the cavity of hollow, are provided with the bottom punch 11 stretched out in the hollow cavity of former 10 downwards;
The workbench 13 of hydraulic press is fixed with middle template 14, middle template 14 center of top is provided with lower pressure pad 15, the central authorities of lower pressure pad 15 are fixed with lower cover 16, and the end of bottom punch 11 connects with the end face of lower pressure pad 15, and bottom punch 11 is fixed in middle template 14 by lower cover 16.
The inner side that the two ends of negative template 7 are positioned at lead 3 is extended with two downwards with lower lead 12; Lower lead 12 is passed down through middle template 14 and middle deck 13, and the end of lower lead 12 is fixed with lower bolster 17, and the lower end central authorities of lower bolster 17 are fixedly linked by the lower oil cylinder 19 of lower lock block 18 with hydraulic press.
Cope match-plate pattern and press slide are by T-slot screw attachment, and middle template and press bed are by T-slot screw attachment, and the lower end of lower bolster connects with screw the outer square nut that lower oil cylinder head pushed down by 2 briquettings, thus reach and the connection of lower oil cylinder.
In addition negative template has the powder feeding plate that 12mm is thick, powder feeding box both sides press strip is fixed, and prevent both sides sideslip just, upper end, without press strip, is pushed down downwards all the time by compression cylinder.
For avoiding generation magnetic and the wear-resisting powder feeding box copper material that needs to process, feeding is two powder feed systems, and powder bucket connects two tube cell heads by the rubber tube cell of two resilient enough.The forward cylindrical place, stage casing that tube cell head is about 200mm cylindrical is spherical, is compressed by powder feeding box afterbody two pieces of spherical pressing plates.Front end is directly fixed on the center of powder box, can adjust the angle direction of feeding head powder feeding.The advantage of this cartridge designs is: the powder got off from hopper is directly sent in former by feeding head, instead of first fills up powder box, and powder box has arrived former eloquence and dropped down in former.Two tube cell is directly sent into and can not be left powder feeding dead angle, is especially applicable to the filling of the elongated like this powdered metal parts of valve guide bushing.
Under 4 post 63T press of transformation are that the latter half of mould bases is moved to workbench through workbench, though such press guide pillar does not lengthen, therefore the lower guide pillar of mould bases also cannot shorten, and also slightly lengthens.The length range planted agent of lower guide pillar comprise the maximum filling of negative template and stripper distance from, longitudinal space installed by bottom punch, middle template is thick, press bed is thick and lower bolster operating range 5 partial-length composition.
4 diameters are adopted for improving rigid design
guide pillar, guide pillar two ends are enclosed constructions that negative template and lower bolster are fixed.Owing to being special valve guide bushing special molding, as long as reserve the space of installation mold, the centre-to-centre spacing of lower guide pillar reduces as much as possible, is designed to 180 × 180mm.What middle template matched with guide pillar is 4 high-precision linear axle sleeves.
For improving mould bases stationarity at work, coordinate with two upper guide posts between cope match-plate pattern and former.One end is fixed on cope match-plate pattern, and what coordinate with it is two high-precision linear axle sleeves on negative template.Contrary with lower guide pillar, the Breadth Maximum that the better pressing machine of spacing its stationarity larger of two upper guide posts can provide and powder feeding box horizontal space, the upper guide post centre-to-centre spacing of this mould bases is 280mm.The length of suitable growth upper guide post makes it not leave contacting of guide pin bushing linear in negative template in any duty.This guide pillar diameter is
long is 450m m, and firm in order to what increase that upper guide post is arranged on cope match-plate pattern, upper guide post holder diameter suitably strengthens, highly increases, by the way of heating guide pillar holder by guide pillar and holder interference fit
It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
