Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with being embodied as
This programme is discussed in detail by example further.
As shown in Figures 3 to 5, the flanging die that this utility model embodiment provides, it includes die, has convex shape end
The punch 31 in portion 32, the lower bolster 51 being connected with the following table of lathe, push rod 61 and die shank 21, wherein, one end of die shank 21
Being connected with punch 31, the other end of die shank 21 is connected with the slide block on lathe；Die includes two female die block 41 being oppositely arranged,
First end of two female die block 41 collectively forms the groove structure for matching with convex shape end 32；The second of two female die block 41
End is rotationally connected with two bases 42 respectively, and base 42 is connected with lower bolster 51；Push rod 61 passes the through hole on lower bolster 51 with recessed
First end of module 41 abuts against；Female die block 41 has discharge position and shaping position.It is understood that the putting of female die block 41
Material position, is when the first end of female die block 41 can contact with the blank 71 to be processed of horizontal positioned residing for female die block 41
Position；The shaping position of female die block 41, is female die block 41 and is in level, and blank 71 completes female die block during flange molding
Position described in 41.
This utility model embodiment provide flanging die, the first end of its two female die block 41 collectively form for punch
The groove structure matched in the convex shape end 32 of 31, and two female die block 41 are rotationally connected with two bases 42 respectively, this makes
In the flange forming process of blank 71, two female die block 41 can move downwardly together along with punch 31 and blank 71, two female die block
The position contacted can be kept with blank the most more on 41, so that the controlled degree of blank 71 is preferable, and then make this
Stamping parts after flanging die flange molding can have preferable quality, greatly reduces percent defective.
Specifically, base 42 can be U-shape structure, and the opening of U-shape structure is towards lower bolster 51；Second end of female die block 41
Being positioned in the opening of U-shape structure, female die block 41 is connected with the two side of U-shape structure by rotary shaft 43, so that base 42
The support that female die block 41 more can be consolidated.It is understood that now blank 71 can be preferably positioned at recessed
Between upper surface and the base plate of base 42 of module 41；Female die block 41 rotates around the axis of rotary shaft 43.
In another embodiment of the present utility model, permissible with one end that the first end of female die block 41 abuts against on push rod 61
Being provided with circular top plate 62, circular top plate 62 is between female die block 41 and lower bolster 51, and the diameter of circular top plate 62 is more than logical
The diameter in hole such that it is able to effectively increase the contact area between push rod 61 and female die block 41, it is also possible to be effectively prevented from top
Bar 61 is deviate from from through hole.It is understood that for the ease of processing, circular top plate 62 can be coaxially disposed with push rod 61；For
Save installation operation, it is simple to mass production, circular top plate 62 and push rod 61 can also form integral structure.
Further, between the first end of two female die block 41, gap can be provided with, so that two female die block 41 are rotating
Time can be more smoothly.
It addition, base 42 can removably connect with lower bolster 51, so that both maintenances and replacing are the most square
Just.
As shown in Figure 4, in order to easily die shank 21 and punch 31 are keeped in repair, die shank 21 can be provided with peace
Dress plate 22, installing plate 22 is provided with the installing hole for being connected with punch 31.
The general work process of the flanging die that this utility model embodiment provides is: first two female die block 41 are at push rod 61
Under the effect of thrust, the axis around rotary shaft 43 is rotated upwardly to discharge position, as shown in Figure 3；Now base 71 is placed on die
On block 41, blank 71 is played the role of positioning by the both sides of base 42, and hereafter punch 31 moves downward, and contacts with blank 71, by blank
71 are pressed on female die block 41, and female die block 41, blank 71 and push rod 61 move downward under the effect of punch together；Work as female die block
41 when being in level, i.e. completes the flange molding of blank 71, and now female die block 41 is in shaping position, as shown in Figure 5；With
Rear die shank 21 drives punch 31 up, and push rod 61 promotes female die block 41 to rotate up around the axis of rotary shaft 43, after molding
Blank 71 is released, thus completes molding and the abjection of stamping parts.
The above is only preferred implementation of the present utility model, it should be pointed out that these embodiments are only used for
Bright this utility model rather than limit scope of the present utility model, and, after having read content of the present utility model, this
This utility model can be made various change or amendment by field person skilled, and these equivalent form of values fall into the application equally
Appended claims limited range.
