Abstract
The utility model discloses a drawing die capable of carrying out blank pressing. The drawing die capable of carrying out the blank pressing comprises a male die and a female die, the male die is connected with an inner sliding block, the inner sliding block is connected with a crankshaft through a first connecting rod, a first cam and a second cam are distributed on the two sides of the crankshaft in a symmetry mode, a second connecting rod and a first outer sliding block are connected on the lower portion of the first cam in sequence, a third connecting rod and a second outer sliding block are connected on the lower portion of the second cam in sequence, and blank pressing rings are arranged between the male die and the first outer sliding block and between the male die and the second outer sliding block. According to the drawing die capable of carrying out the blank pressing, by the adoption of the rigid blank pressing function, blank holder force does not change with the drawing depth of a drawn workpiece and maintains unchanged in size, the workpiece is not prone to cracking due to drawing, and the drawing effect is good.
Description
Technical field
The utility model relates to a kind of Drawing Die, especially a kind of Drawing Die that makes the workpiece flanging.
Background technology
Drawing Die, when the pull and stretch workpiece, has flanging for making the workpiece both sides, usually flange fixing installation need to be set, and now commonly used is the spring flange fixing installation, namely by elastic pressure, makes it produce flanging as the pressure-pad-force to workpiece.But this pressure-pad-force is to increase along with the continuous increase of drawing depth, and workpiece is along with the increase of drawing depth, and material is constantly reducing, the pressure-pad-force needed also reduces gradually, therefore, just easily cause the workpiece drawing crack in case drawing depth is excessive, generation is scrapped.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of pressure-pad-force with drawing depth, not change, but the flanging Drawing Die that size all remains unchanged.
For achieving the above object, the technical solution of the utility model is: but a kind of flanging Drawing Die, comprise punch, die, punch is connected with inner slide, inner slide is connected with bent axle by first connecting rod, and the bent axle bilateral symmetry is distributed with the first cam and the second cam, and the first cam below is connected with second connecting rod, the first outer slide in turn, the second cam below is connected with third connecting rod, the second outer slide in turn, is provided with blank holder between punch and the first outer slide, the second outer slide.
The beneficial effects of the utility model are: by the rigid blank holder effect, pressure-pad-force does not change and changes with the drawing depth by the pull and stretch workpiece, and size all remains unchanged, and workpiece is difficult for by drawing crack, and pull and stretch is effective.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: punch 1, die 2, inner slide 3, first connecting rod 41, second connecting rod 42, third connecting rod 43, bent axle 5, the first cam 61, the second cam 62, the first outer slide 71, the second outer slide 72, blank holder 8.
The specific embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, but a kind of flanging Drawing Die, comprise punch 1, die 2, punch 1 is connected with inner slide 3, inner slide 3 is connected with bent axle 5 by first connecting rod 41, and bent axle 5 bilateral symmetry are distributed with the first cam 61 and the second cam 62, the first cam 61 belows are connected with second connecting rod 42, the first outer slide 71 in turn, the second cam 62 belows are connected with third connecting rod 43, the second outer slide 72 in turn, are provided with blank holder 8 between punch 1 and the first outer slide 71, the second outer slide 72.
Operation principle of the present utility model is: during bent axle 5 rotation, first by the first cam 61 and the second cam 62, drive the first outer slides 71 and the second outer slide 72 makes blank holder 8 that workpiece is pressed on die 2, by inner slide 3, drive 1 pair of workpiece of punch subsequently and carry out pull and stretch, in drawing process, the first outer slide 71 and the second outer slide 72 keep motionless.
