Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, and the most same or similar label represents same or similar element or has the element of same or like function.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.
Below with reference to the accompanying drawings punching die according to this utility model embodiment is described.
As Figure 1-3, punching die according to this utility model embodiment, it includes upper bolster 100, is arranged on the die shoe (not indicating in figure) below described upper bolster 100, and it is arranged on described upper bolster 100 and is flexibly connected with described upper bolster 100 holding pad 300 coordinated, it is provided with tapered wedges 400 on described upper bolster 100, and supports described tapered wedges 400 drive block 500 that can move down under the drive of described tapered wedges 400；Described holding pad 300 is provided with slide block 700, and described slide block 700 moves down under described drive block 500 drives；The periphery of described slide block 700 is arranged with the guide pin bushing 800 guiding slide block 700, and described guide pin bushing 800 is fixed on described holding pad 300；Described punching die also includes that drift 900, described drift 900 are fixed on described slide block 700 by punch fixing plate 200.
At this it should be noted that described holding pad 300 is arranged on described upper bolster 100, under the driving of driver part can on described upper bolster 100 movably with the variation of the miscellaneous part generation position relationship on described upper bolster 100.
At this it should be noted that described drift 900 is connected on described slide block 700, and being slidably fixed under the guiding of described guide pin bushing 800 on described holding pad 300 with described slide block 700, described guide pin bushing 800 is fixed on described holding pad 300.
It should be noted that at this, the periphery of described drift 900 is provided with back-moving spring (not indicating in figure), when resetting after the punching of described drift 900, back-moving spring gives restoring force, described drift 900 gives described slide block 700 1 and replys impulse force, drives described slide block 700 to move up downward along described guide pin bushing 800 leading of described guide pin bushing 800.
Therefore, it is capable of reducing the volume size of punching die according to the punching die of this utility model embodiment, overcomes mould volume big, the problems such as the big and manufacturing cost of taking up room is high.
As it is shown in figure 1, the both sides of described slide block 700 are provided with can limit the limiting plate 600 that described slide block 700 rotates, described limiting plate 600 is fixed on described binder block 300.
At this it should be noted that the face that contacts with each other of described limiting plate 600 and described slide block 700 is plane, described limiting plate 600 can limit circumferentially rotating of described slide block 700.
As shown in Figure 1, 2, described limiting plate 600 is split-type structural, is arranged on the both sides of described slide block 700.
At this it should be noted that described limiting plate 600 can be set to two pieces, it is arranged in the both sides of described slide block 700, thus limits circumferentially rotating of described slide block 700.
As shown in Figure 1, 2, it is provided with between described punch fixing plate 200 and described slide block 700 and resists the backing plate 1000 of described Impulsive force of punch pin.
It should be noted that at this; when the action of described drift 900 is punched out when; described slide block 700 produces the biggest recoil strength, and described backing plate 1000 can keep out and alleviate the counteracting force of the most described drift 900, have the effect of protection to connection members such as described slide blocks 700.
Further, described slide block 700 is cylinder, and described guide pin bushing 800 is linked in the outside of described slide block 700 for torus.
At this it should be noted that the laminating of toric described guide pin bushing 800 is enclosed within the outside of described cylindrical described slide block 700, and described slide block 700 can be guided, it is ensured that the accuracy of described drift 900 punching.
Further, the upper end of described slide block 700 is set to L font, and deducting with described drive block 500 phase in the upper end of described slide block 700, described slide block 700 can move down under the drive of described drive block 500.
Further, described drift 900 is conflicted with described die shoe under described slide block 700 drives.
At this it should be noted that described drift 900 is punched out with the conflict of described die shoe under the drive of described slide block 700.
Further, described slide block 700 is cuboid, and described guide pin bushing 800 is the outside that four frameworks are linked in described slide block 700.
It should be noted that at this, described slide block 700 can be cuboid, be linked in the described guide pin bushing 800 that described slide block 700 outside is four frameworks when described slide block 700 is for cuboid, described guide pin bushing 800 is fitted in described slide block 700 outside and guides described slide block 700.
Punching die of the present utility model substantially reduces with existing punching die phase specific volume；Greatly reduce the manufacturing cost of punching die simultaneously, be provided with described guide pin bushing in the outside of described slide block simultaneously and the movement of described slide block is guided, improve the accuracy of described drift punching, decrease rocking of described slide block.
