In order to achieve the above object, the utility model provides following technical scheme: a kind of lock pad punching out blanking die, it is characterized in that, and comprising:
Patrix, it comprises upper bolster, die shank, backing plate, punch retainer, punch, described die shank is positioned at the centre position of upper bolster, the upper surface that upper bolster is passed on its top stretches out vertically upward, its bottom is connected with the described backing plate that is positioned at the upper bolster below, and described punch retainer is positioned at the backing plate below, and it is connected with the lower surface of backing plate, wherein be provided with the punch that stretches out vertically downward, the bottom sectional dimension of described punch is less than the tip section size; Described patrix also comprises stripper, spring, and described stripper is fixed on the punch below, and it is connected with upper bolster by spring; Described patrix also comprises the guide pin bushing of vertical fixing in the upper bolster lower surface;
Counterdie, it comprises die shoe, die, guide pillar, the sword wall of described die is provided with gradient, it is positioned at die shoe top and the corresponding position of punch, the tip section size of described punch is less than the cutting edge sectional dimension of die, form the gap at the cutting edge place during matched moulds, described guide pillar and guide pin bushing are complementary, and its vertical fixing is in the upper surface of die shoe;
Described upper die and lower die are installed relatively.
Preferred as technique scheme, described patrix also comprises shoulder, it is arranged on the junction of described punch and punch retainer.
Preferred as technique scheme, described counterdie also comprises alignment pin, it is installed on the upper surface of described die.
Preferred as technique scheme, the quantity of described guide pillar is two, it is fixed on the upper surface both sides of die shoe symmetrically.
The lock pad punching out blanking die that the utility model provides, the bottom sectional dimension that has reduced punch is to improve pressure, with the sword wall of die be arranged to gradient with guarantee towards part can be in time by the sword hole, enter the portion of stepping down, and by the cutting edge gap being set to reduce wearing and tearing to die sword wall, this has not only improved punching precision and production efficiency, and reduced production cost, prolonged the service life of equipment.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do simple the introduction to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the lock pad punching out blanking die of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is carried out clear, complete description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of lock pad punching out blanking die that the utility model embodiment provides, comprise: patrix, it comprises upper bolster 1, die shank 2, backing plate 3, punch retainer 4, punch 5, described die shank 2 is positioned at the centre position of upper bolster 1, the upper surface that upper bolster 1 is passed on its top stretches out vertically upward, its bottom is connected with the described backing plate 3 that is positioned at upper bolster 1 below, described punch retainer 4 is positioned at backing plate 3 belows, its lower surface with backing plate 3 is connected, wherein be provided with the punch 5 that stretches out vertically downward, the bottom sectional dimension of described punch 5 is less than the tip section size; Described patrix also comprises stripper 6, spring 7, and described stripper 6 is fixed on punch 5 belows, and it is connected with upper bolster 1 by spring 7; Described patrix also comprises the guide pin bushing 8 of vertical fixing in upper bolster 1 lower surface; Counterdie, it comprises die shoe 9, die 10, guide pillar 11, the sword wall of described die 10 is provided with gradient, it is positioned at die shoe 9 tops and punch 5 corresponding positions, the tip section size of described punch 5 is less than the cutting edge sectional dimension of die 10, form the gap at the cutting edge place during matched moulds, described guide pillar 11 is complementary with guide pin bushing 8, and its vertical fixing is in the upper surface of die shoe 9; Described upper die and lower die are installed relatively.
