Fig. 1 is according to the structural representation of the diel of the utility model embodiment.
Diel 100, punch 1, pressing plate 2, raw material cavity volume 3, the sub-back-pressure ejector 42 of the sub-back-pressure ejector 41, second of back-pressure ejector 4, first, die 5, pressure tooth 6.
The specific embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to Fig. 1, describe according to the diel 100 of the utility model embodiment.As shown in Figure 1, according to the diel 100 of the utility model embodiment, comprise pressing plate 2, punch 1, back-pressure ejector 4, die 5 and raw material cavity volume 3.
The lower surface of pressing plate 2 is provided with presses tooth 6.Punch 1 runs through pressing plate 2 along the vertical direction, and the lower end of punch 1 is stretched out pressing plate 2 downwards.In back-pressure ejector 4, there is the unlimited container cavity in upper end.Die 5 is located in described container cavity, and die 5 is relative with punch 1.Raw material cavity volume 3 is located between back-pressure ejector 4 and pressing plate 2.
In utilization, according to 100 pairs of raw material of diel of the utility model embodiment, add man-hour, raw material can be put into raw material cavity volume 3, then before punching press, utilize the pressure tooth 6 on pressing plate 2 lower surfaces, along punching press periphery periphery, raw material cavity volume 3 is applied to crunch.Meanwhile, back-pressure ejector 4 clamps raw material to carry out punching press.Like this, the state of the raw material in Pressing Deformation district in three-dimensional compressive stress, thus increased raw-material plasticity, delayed the generation of shear fissure, strengthened section light face region.And, owing to having adopted minimum gap, thereby can make blanking part quality greatly improve.
According to the diel 100 of the utility model embodiment, by arranging on the lower surface at pressing plate 2, press tooth 6, thereby before punching press, utilize the pressure tooth 6 on pressing plate 2 lower surfaces, along punching press periphery periphery, raw material cavity volume 3 is applied to crunch, to allow raw material just be subject to powerful pressure before carrying out punching press, thereby greatly increased raw-material plasticity, improved the precision of product.And, by back-pressure ejector 4 is set, thereby can make raw material can be clamped closely when being subject to punching press, delayed thus the generation of shear fissure, promoted the roughness of product.
Therefore, according to the diel 100 of the utility model embodiment, there is easy to use, machining accuracy advantages of higher.
As shown in Figure 1, advantageously, pressing tooth 6 can be annular.Before punching press, can utilize thus the pressure tooth 6 on pressing plate 2 lower surfaces, along punching press periphery periphery, raw material cavity volume 3 is applied to crunch more, to allow raw material just be subject to more powerful pressure before carrying out punching press, thereby further increased raw-material plasticity, further improved the precision of product.
Further preferably, pressing tooth 6 can be annular.Before punching press, can utilize thus the pressure tooth 6 on pressing plate 2 lower surfaces, along punching press periphery periphery, raw material cavity volume 3 is applied to pressure more uniformly, to allow raw material just be subject to pressure more uniformly before carrying out punching press.
It can be a plurality of pressing tooth 6, and a plurality of pressure teeth 6 can arrange at interval, presses in teeth 6 one can be located at adjacent two to press in another in teeth 6 for adjacent two.That is to say, press described another in tooth 6 can be set in outside adjacent two described of pressing in tooth 6 for adjacent two.
Before punching press, can utilize thus the pressure tooth 6 on pressing plate 2 lower surfaces, along punching press periphery periphery, raw material cavity volume 3 is applied to more powerful, uniform pressure, to allow raw material just be subject to more powerful, uniform pressure before carrying out punching press, thereby further increased raw-material plasticity, further improved the precision of product.Particularly, each pressure tooth 6 can be annular.
In a concrete example of the present utility model, a plurality of pressure teeth 6 can form concentric circles.Before punching press, can utilize thus the pressure tooth 6 on pressing plate 2 lower surfaces, along punching press periphery periphery, raw material cavity volume 3 is applied to more powerful, uniform pressure, to allow raw material just be subject to more powerful, uniform pressure before carrying out punching press, thereby further increased raw-material plasticity, further improved the precision of product.Particularly, each pressure tooth 6 can be annular.
A plurality of pressure teeth 6 can arrange equally spacedly.That is to say, the distance between adjacent two pressure teeth 6 can be certain.Before punching press, can utilize thus the pressure tooth 6 on pressing plate 2 lower surfaces, along punching press periphery periphery, raw material cavity volume 3 is applied to more powerful, uniform pressure, to allow raw material just be subject to more powerful, uniform pressure before carrying out punching press, thereby further increased raw-material plasticity, further improved the precision of product.Particularly, each pressure tooth 6 can be annular.
The cross section of pressing tooth 6 can be triangle (as shown in Figure 1), trapezoidal, rectangle or square.When pressing tooth 6 to be annular, the cross section of pressing tooth 6 can be the radial section of pressing tooth 6.
Press tooth 6 and pressing plate 2 to be integrally formed.Not only can improve thus the structural strength of pressing plate 2, and can reduce manufacture difficulty and the manufacturing cost of pressing plate 2.
As shown in Figure 1, in examples more of the present utility model, the upper surface of die 5 can be positioned at the below of the upper surface of back-pressure ejector 4.Can make thus the structure of diel 100 more reasonable.
As shown in Figure 1, back-pressure ejector 4 can comprise between the first sub-back-pressure ejector 41 and the sub-back-pressure ejector 41 of the second sub-back-pressure ejector 42, the first and the second sub-back-pressure ejector 42 and can limit described container cavity.Can make thus the structure of diel 100 more reasonable.
Particularly, the upper surface of die 5 can be positioned at the below of the upper surface of the first sub-back-pressure ejector 41, and the upper surface of die 5 can be positioned at the below of the upper surface of the second sub-back-pressure ejector 42.
The corner of back-pressure ejector 4 can be R angle.Can make thus the structure of diel 100 more reasonable.
