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, in described hollow die shank 2, is provided with knockout rod 1 moving up and down; The middle part of described top mold frame 3 is disposed with the first die liner plate 4, the second die liner plate 5 and die 6 downwards; The lower end of described knockout rod 1 is connected on the dnockout piece 11 in the central through hole that is arranged at described the first die liner plate 4; The second die liner plate 5 lower ends are provided with the compound punch assembly 8 in the through hole that is embedded in described die 6 middle parts, are provided with the oblique tank structure 7 being embedded in described compound punch assembly 8 on 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, described the second punch liner plate 26 middle parts are upwards provided with punch 23, described punch 23 upper levels are provided with stripper 24, between described stripper 24 and described the second punch liner plate 26, are formed with hollow cavity; Described the second punch liner plate 26 both sides embed discharging spring assembly 25, and described discharging spring assembly 25 upper ends are fixed on described stripper 24.
In patrix, between described top mold frame 3, the first die liner plate 4, the second die liner plate 5 and die 6, be formed with the patrix installing hole 9 fixing for bolt.The upper surface of the lower surface of dnockout piece 11 and described the second die liner plate 5 fits together.
