Described mould bases comprises the cope match-plate pattern be arranged on press slide, the two ends of cope match-plate pattern are fixed with the two upper leads stretched out downwards, the lower shoe central authorities of cope match-plate pattern are fixed with pressure pad, and the bottom surface central authorities of upper pressure pad are fixed with upper press cover, and the central authorities of upper press cover are fixed with the upper punch stretched out downwards;
The mid portion of two upper leads is provided with negative template, and negative template is set on upper guide post and also can moves up and down along upper guide post, and negative template upper surface is fixed with powder feeding plate, and powder feeding plate is fixed with dust feeder;
The central authorities of negative template are provided with the former of the strip stretched out downwards, and former is the cavity of hollow, is provided with the bottom punch stretched out in the hollow cavity of former downwards;
The middle part workbench of described common four-column hydraulic press is fixed with middle template, middle die head central authorities are provided with lower pressure pad, the central authorities of lower pressure pad are fixed with lower cover, and the end of bottom punch connects with the end face of lower pressure pad, and bottom punch is fixed in middle template by lower cover;
The inner side that the two ends of negative template are positioned at lead is extended with two downwards with lower lead, lower lead is passed down through middle template and middle part workbench, the end of lower lead is fixed with lower bolster, and the lower end central authorities of lower bolster are fixedly linked by the lower oil cylinder of lower lock block and common four-column hydraulic press.
The beneficial effects of the utility model are: little to the change of common hydraulic press, common press just can be made to become the moulding press of powder metallurgy valve guide pipe by simply transforming, and improved precision and stationarity do not reduce, the expense purchasing special moulding press in a large number can be saved.
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 new automatic powder metallurgy valve guide pipe Special purpose pressing machine, comprise common four-column hydraulic press and be arranged on the mould bases on common four-column hydraulic press, common four-column hydraulic press is arranged in foundation ditch 21, hydraulic mechanism 20 is connected with frame by conduit, the press slide 1 of common press 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, 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 middle deck 13 of common 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 common press.
Due to calculate mould bases height be greater than press can placement space.Mould bases is not directly placed on press bed.Under mould in mould bases is put into press bed with lower part.Middle template can be fixed on press bed by such design, only need to pull down press ejection cylinder, workbench expands 4 holes, under mould bases, guide pillar connects lower bolster through press bed, the ejection cylinder pulled down is fixed on former fixed screw with support again, its position is to bottom offset, and cylinder head can be connected on lower bolster.Press base is constant, also can be arranged on original position, is to excavate a trench to vacate the position of lower cylinder under the ground of press.This scheme overall press changes little, and precision and stationarity do not reduce.Both economical.
Common four-column hydraulic press, without powder feeder unit, also cannot increase this system in original hydraulic system.The compressed air gas source that we utilize the air compression station in factory to provide, includes in cylinder powder feeding in full-automatic PLC control system.
Press automation adopts the integrated electrical equipment control of PLC, and utilize the compressed air gas source two of original hydraulic system of press and factory to overlap power source, action signal has proximity switch and pressure switch two powder.This valve guide bushing special molding press operation program has two cover crawls-for adjustment, full-automatic-for the forming action of continuous circulation.
Crawl knob is rotated in start, after adjusting the stroke of each active section, then origination action position is adjusted in action, the full-automatic knob of turn, just can carry out Full-automatic circulation compacting.As encountered problems in the course of work, press the red button of emergent stopping, system can be stopped immediately at that active section.Arrive Deng operating personnel, after adjusting from crawl, get back to start bit, the more full-automatic knob of turn just can work on.
Full auto-programs is: top shoe backhaul-liftout tank ejects-powder feeding cylinder move ahead-powder feeding cylinder stage casing (powder feeding cylinder move ahead stage casing iterative cycles 5 times)-powder feeding cylinder retrogressing-top shoe at a slow speed descending-compacting of floating-rear pressure-pressurize-pressure release-top shoe backhaul-liftout tank return-liftout tank ejects.After passing into Compressed Gas in addition, the compression cylinder of dust feeder is in and often stretches out state.
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.
