The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 1, a kind of distortion-free elasticity essence that invention provides rushes to mode structure, comprise upper mould device, it also comprises the punch 4 that is installed on upper mould device lower end, and is installed on the elastic pressuring clamping device that described upper mould device lower end compresses for the workpiece 8 to upper mould device lower end.
Consult shown in Fig. 2, concrete, the elastic pressuring clamping device adopting in the present invention is nitrogen spring 5, this nitrogen spring 5 comprises the spring base 54 that is provided with seal chamber 53, and the piston body 51 on the liftable seal chamber 53 that is installed on spring base 54 is installed on the patrix stripper plate 6 of spring base 54 lower ends, and be located at the qi of chong channel ascending adversely hole 52 on the piston body 51 in seal chamber 53, and qi of chong channel ascending adversely hole 52 also rushes nitrogen device and is connected with one, and the upper end of piston body 51 is installed on upper mould device.In the present embodiment, adopting piston body 51 is T shape structure.
Upper mould device in the present invention comprises upper base plate 1, upper die plate 2 and patrix jam plate 3, wherein, upper die plate 2 is installed on the lower end of upper base plate 1, patrix jam plate 3 is installed on the lower end of upper die plate 2, punch 4 is fixed on the lower end of upper die plate 2 through patrix jam plate 3, and the upper end of piston body 51 is installed on the lower end of upper base plate 1 after through patrix jam plate 3 and upper die plate 2.
Consult shown in Fig. 3 and Fig. 4, the structure chart of the mould forming for upper die structure of the present invention, this mould also comprises lower mold apparatus, the die corresponding with punch 4 10 is installed, wherein on lower mold apparatus, the diameter of die 10 is greater than the diameter of punch 4, be negative clearance pattern, can make whole mould in stamping-out process, the smooth smooth and Wu Ta limit, corner of the stamping-out edge of a knife, reduce the loss of material simultaneously, improved production efficiency.
And lower mold apparatus comprises counterdie solid plate 9, counterdie backing plate 11 and counterdie seat board 12, the solid plate 9 of counterdie is installed on counterdie backing plate 11, and counterdie backing plate 11 is installed on counterdie seat board 12, and die 10 is installed on counterdie backing plate 11 and is sheathed on the inner side of the solid plate 9 of counterdie.Meanwhile, the location-plate 7 for workpiece 8 is positioned is also installed in the upper end of die 10.
In the mold work principle that 1～Fig. 4 forms upper die structure of the present invention by reference to the accompanying drawings, be described further below:
Before stamping-out, first workpiece 8 is positioned over to the upper end of die 10, and position with location-plate 7, by rushing nitrogen device (not shown), to the seal chamber 53 of spring base 54, be filled with nitrogen again, under the effect of nitrogen pressure, piston body 51 moves downward and drives patrix stripper plate 6 workpiece pressing 8(as shown in Figure 3), like this, can prevent workpiece 8 in stamping-out process and lift up because of stamping-out distortion, make surfacing, guaranteed that the deformation force of the pressure ratio workpiece 8 that patrix stripper plate 6 is pressed in stamping-out process is large.Then, by forcing press, driving upper mould device descending, making punch 4 blankings 8, and then waste material drops out from die 10 slug holes of lower mold apparatus, complete stamping-out (as shown in Figure 4).
In Fig. 5, that Fig. 5 a and 5b show is the Workpiece structure figure that does not rush mesopore, and that Fig. 5 c and Fig. 5 d demonstration is the Workpiece structure figure rushing after mesopore.And through detecting, adopt after Dies ' Blanking of the present invention, the flatness of workpiece 8 can reach 0.15～0.1mm, and the surface smoothness of mesopore can reach
By above-mentioned, structure of the present invention and principle are introduced, upper die structure of the present invention has utilized high pressure nitrogen spring compression workpiece to prevent that in stamping-out process, workpiece has been lifted up because stamping-out is out of shape, make the out-of-flatness of plate face, and the mould that upper die structure of the present invention forms is applicable to plate surface evenness, the stamping-out of the thick blanks that mesopore fineness is had relatively high expectations.Can save the amount of machining under constructed requirement, improve greatly production efficiency.
Although described by reference to the accompanying drawings working of an invention mode; but the patent owner can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of the claim of invention, all should be within the protection domain of invention.
