Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1, Fig. 2 are pressure setting and the method schematic diagram of thin-walled powder metallurgy axle sleeve.As seen from the figure, it includes template 1, template 1 is fixed with counterdie 2, is fixed with the pressing die 3 made with wolfram steel material in counterdie 2, and the endoporus of pressing die 3 is identical with the cylindrical of powder metallurgy axle sleeve 4.The center of pressing die 3 is provided with plug 5, the cylindrical of plug 5 is identical with the endoporus of powder metallurgy axle sleeve 4, the endoporus of pressing die 3 and the cylindrical of plug 5 form the annular die cavity 6 of the metallurgical axle sleeve 4 of pressed powder, the cylindrical of plug 5 is provided with the ejector sleeve 7 releasing powder metallurgy axle sleeve 4, the height of powder metallurgy axle sleeve 4 and ejector sleeve 7 upper surface, to the ratio of distances constant of pressing die 3 upper surface, are the compression ratio of powder metallurgy axle sleeve 4.The lower end of ejector sleeve 7 is connected with the liftout attachment 8 moved up and down, and described liftout attachment 8 is the lifter plate 9 be connected with ejector sleeve 7 lower end, and the two ends of lifter plate 9 are connected with two flexible up and down cylinder piston rods 10 respectively.Above die cavity 6, be provided with the upper punch 11 be connected with slider of punch, the front end of described upper punch 11 is the tubular matched with die cavity 6.What above die cavity 6, be provided with the powder metallurgy powder moved left and right adds tube cell 12, adds tube cell 12 and is connected with the powder bucket 13 that adds of upper end.The described front end adding tube cell 12 is connected with scraping wings 14, and described scraping wings 14 front end is V-arrangement, and the bottom of scraping wings 14 rear end is shaped with groove 15 and adds tube cell 12 mouthfuls and be connected.When adding tube cell 12 and being advanced on die cavity 6, the powder metallurgy axle sleeve 4 ejecting die cavity 6 is pushed away Stamping Area by the V-notch of scraping wings 14.Not blocking to make powder metallurgy powder fall into die cavity 6 smoothly, adding in powder metallurgy powder process, adding tube cell 12 and adding powder bucket 13 is shakes.Also in powder metallurgy powder, add a certain amount of graphite powder material, to increase the mobility of powder metallurgy powder.
The course of work of thin-walled powder metallurgy axle sleeve pressure setting:
