The specific embodiment
Also the present invention is described in detail in conjunction with the embodiments below with reference to accompanying drawing.Need to prove, in the situation that do not conflict, below feature among each embodiment and the embodiment can mutually make up.
The present invention is described in detail as an example of the air-conditioner outdoor unit dividing plate example for the below.
At first in conjunction with the cae analysis technology, simulation sheet metal component forming process is prevented issuable defective, and the factor that affects the tensioning member quality in the air-conditioner outdoor unit dividing plate forming process is analyzed, and determines the structure of mould as shown in Figure 1.Wrinkle resistant sheet metal parts punching die comprises patrix 10 and counterdie 20, and wherein, patrix 10 comprises mounting plate 11, upper bolster 12, cope match-plate pattern 13 and Bending punch 14, and counterdie 20 comprises bottom plate 21, die shoe 22, takes off plate 25, lower bolster 23 and nitrogen spring 24 down.
As shown in Figures 2 and 3, draw by the cae analysis technology, in drawing process, the flow direction of material mainly is width and the length direction of the lower binder surface 231 in Fig. 2, therefore, be provided with two resistance material convex tendons 232 of arranging along the width of lower bolster 23 at lower binder surface 231, be provided with the resistance material groove 132 that cooperates with this resistance material convex tendon 232 at upper binder surface 131.Increase the charging resistance by resistance material convex tendon 232 and resistance material groove 132, regulate the Material Flow situation, enlarge pressure-pad-force, suppress the wrinkling trend of material.Preferably, described resistance material convex tendon 232 is embedded on the described lower bolster 23, with the convenient big or small effect of saving material, processing cost that also plays simultaneously of adjusting resistance material power by shape, the size of regulating the convex tendon mold insert.Preferably, the cross section on described resistance material convex tendon 232 surfaces is circular arc.
Yet, because the length direction of lower binder surface 231 has bending, can not arrange the resistance material convex tendon, therefore, the both sides on the length direction of lower binder surface 231 are provided with process complementary surface 233, in the both sides of cope match-plate pattern 13 Bending punch 14 that cooperates with this process complementary surface 233 are set, by the two ends bending with plate of Bending punch 14 and process complementary surface 233, formation is to the flow resistance of plate, thereby the local Material Flow tendency of adjusting suppresses wrinkling, cracking.
As depicted in figs. 1 and 2, described nitrogen spring 24 is installed on the described bottom plate 21, is provided with the through hole corresponding with this nitrogen spring 24 at described die shoe 22, and the upper end of described nitrogen spring 24 is passed this through hole and withstood on described lower bolster 23 back sides.Preferably, described nitrogen spring 24 is arranged along the length direction of resistance material convex tendon 232.Nitrogen spring 24 is used for providing elastic force between cope match-plate pattern and lower bolster, with further expansion pressure-pad-force.Preferably, connect with tracheae between the nitrogen spring 24, and be connected with Pressure gauge 20, have according to adjustable to guarantee pressure-plate-force balance, pressure size.
In the another embodiment of the present invention, a kind of forming method of sheet metal component is provided, comprise and draw step, deburring step, flange step and punching step, describedly draw the wrinkle resistant sheet metal parts punching die that the employed mould of step is above-described embodiment, all the other steps are same as the prior art, do not repeat them here.
Figure 4 shows that the front and back comparison diagram of the product of producing by wrinkle resistant sheet metal parts punching die of the present invention and the product that adopts prior art to produce, wherein a is the product that prior art processes, the product of b for using wrinkle resistant sheet metal parts punching die shown in Figure 1 to process.As can be seen from the figure, the product by wrinkle resistant sheet metal parts punching die provided by the present invention processes does not have the defectives such as wrinkling, and product is more attractive in appearance, has improved product quality, has shortened the friendship phase, has saved and has repaired a die, changes mould, die trial expense.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
