The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 1, a kind of front plate essence that invention provides is rushed blanking die, comprise upper mould device and lower mold apparatus, it also comprises punch 5 and the die 7 being installed on upper mould device, described punch 5 is positioned at the inner side of die 7, and also comprise and be installed on lower mold apparatus and the counterdie 8 corresponding with punch 5, and the diameter of described counterdie 8 is greater than the diameter of punch 5.
Concrete, in the present invention, upper mould device comprises upper die plate 1, punch retainer 2, up stripper 3 and upper clamping plate 4, and, upper die plate 1 is installed on the lower end of upper clamping plate 4, and punch retainer 2 is installed on the lower end of upper die plate 1, and die 7 is installed on the lower end of punch retainer 2, up stripper 3 matches with the inner side of die 7, and punch 5 matches to merge with the inner side of up stripper 3 and is connected with the lower end of upper die plate 1 through punch retainer 2.And lower mold apparatus comprises lower stripper 9, lower die-cushion 10, counterdie fixed head 11 and counterdie seat board 12, and, lower die-cushion 10 is installed on the upper end of counterdie seat board 12, counterdie fixed head 11 is installed on the upper end of counterdie seat board 12 and is positioned at the outside of lower die-cushion 10, counterdie 8 is installed on the upper end of lower die-cushion 10 and is positioned at the inner side of counterdie fixed head 11, and lower stripper 9 is installed on the upper end of counterdie seat board 12 by an elastic device and is positioned at the outside of counterdie 8; And the diameter of punch 5 is less than the diameter of counterdie 8, adopt the cooked mode of negative clearance, be conducive to improve machining accuracy.
