Detailed description of the invention
Shown in Fig. 1, Fig. 2, relate to a kind of stamping die for thrust bearing, comprise the patrix with top mold frame 3 and the counterdie with lower mold holder 28, the both sides of described top mold frame 3 extend to form symmetrical upper hollow cylinder 31 downwards, the middle part of described top mold frame 3 is upwards extended with columniform hollow die shank 2, is provided with knockout rod 1 moving up and down in described hollow die shank 2; The middle part of described top mold frame 3 is disposed with the first die liner plate 4, second die liner plate 5 and die 6 downwards; The lower end of described knockout rod 1 is connected on the dnockout block 11 in the central through hole being arranged at described first die liner plate 4; Second die liner plate 5 lower end is provided with the compound punch assembly 8 in the through hole that is embedded in the middle part of described die 6, described compound punch assembly 8 is provided with the oblique tank structure 7 be embedded in described compound punch assembly 8.
The both sides of described lower mold holder 28 upwards extend to form the lower hollow cylinder 32 corresponding with described upper hollow cylinder 31, the middle part of described lower mold holder 28 is upwards disposed with the first punch liner plate 27 and the second punch liner plate 26, punch 23 is upwards provided with in the middle part of described second punch liner plate 26, described punch 23 upper level is provided with stripper 24, is formed with hollow cavity between described stripper 24 and described second punch liner plate 26; Described second punch liner plate 26 both sides are embedded with discharging spring assembly 25, and described discharging spring assembly 25 upper end is fixed on described stripper 24.
In patrix, be formed for the fixing patrix installing hole 9 of bolt between described top mold frame 3, first die liner plate 4, second die liner plate 5 and die 6.The lower surface of dnockout block 11 and the upper surface of described second die liner plate 5 fit together.
In counterdie, be formed between lower mold holder 28, first punch liner plate 27, second punch liner plate 26 and stripper 24 for the fixing counterdie installing hole 29 of bolt.Be provided with locating pin spring 21 in hollow cavity, described locating pin spring 21 one end is connected on described second punch liner plate 26, and the other end is fixedly connected with the auxiliary positioning pin 22 longitudinally through described stripper 24.Wherein, the middle part of punch 23 is also provided with the punch alignment pin 221 corresponding with the described compound punch assembly 8 in patrix.
