Description

A kind of passenger car punching mold notch structure
Technical field
The present invention relates to a kind of passenger car punching mold notch structure, belong to passenger car technical field of mold。
Background technology
At present, the knife edge structure of passenger car die cutting die touches type for flat, and the flat type edge of a knife that touches is that this structure is applicable to smooth die face, for die-cut most employing high pressure waterjet of precipitous profile by the die-cut product fabric that cuts off of normal direction。
Summary of the invention
It is an object of the invention to overcome above-mentioned weak point, it is provided that a kind of passenger car punching mold notch structure, adopt this structure can excise effective profile of product clout retained product while formed product according to product contour line。
According to technical scheme provided by the invention, a kind of passenger car punching mold notch structure, including upper die body and lower mold body;Have upper die body notch on the downside of described upper die body, in upper die body notch, be provided with the mould edge of a knife;Have lower mold body notch on the upside of lower mold body, in lower mold body notch, be provided with the counterdie edge of a knife;It is interference fit between the described upper mould edge of a knife and the counterdie edge of a knife。
The described upper mould edge of a knife is fixed in upper die body notch;The counterdie edge of a knife is fixed in lower mold body notch。The described upper mould edge of a knife is by being fixedly welded in upper die body notch;The counterdie edge of a knife is by being fixedly welded in lower mold body notch。
Described upper die body notch length is consistent with upper die body length, and width is 6mm, and the degree of depth is 6mm;The length of described lower mold body notch is consistent with lower mold body length, and width is 6mm, and the degree of depth is 6mm。The depth and width of the described upper mould edge of a knife are all consistent with upper die body notch;The degree of depth of the counterdie edge of a knife is consistent with lower mold body notch, and the width of the counterdie edge of a knife is more than the width of lower mold body notch。
The hardness of the described upper mould edge of a knife is more than the hardness of the counterdie edge of a knife。The material of the described upper mould edge of a knife is SKD11, and the material of the counterdie edge of a knife is H13。
Time prepared by inventive die, on upper die body, first first open upper die body notch, then the upper mould edge of a knife is welded on upper die body notch;Described lower mold body is opened lower mold body notch again, the lower mold body edge of a knife is freezed on lower mold body notch;Product fabric defines product and product surplus after upper die body moves down punching press lower mold body。
Beneficial effects of the present invention: present configuration is simple, intensity is high, not easy to wear, by lateral shear product, it may be achieved formed product and cutting products appearance profile carry out, and decrease the manufacturing process of product, improve production efficiency simultaneously。

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described。
As Figure 1-3: a kind of passenger car punching mold notch structure, including upper die body 1 and lower mold body 4;Have upper die body notch 8 on the downside of described upper die body 1, in upper die body notch 8, be provided with the mould edge of a knife 2;Have lower mold body notch 9 on the upside of lower mold body 4, in lower mold body notch 9, be provided with the counterdie edge of a knife 5;It is interference fit between the described upper mould edge of a knife 2 and the counterdie edge of a knife 5。
The described upper mould edge of a knife 2 is fixed in upper die body notch 8;The counterdie edge of a knife 5 is fixed in lower mold body notch 9。The described upper mould edge of a knife 2 is by being fixedly welded in upper die body notch 8;The counterdie edge of a knife 5 is by being fixedly welded in lower mold body notch 9。
Described upper die body notch 8 length is consistent with upper die body 1 length, and width is 6mm, and the degree of depth is 6mm;The length of described lower mold body notch 9 is consistent with lower mold body 4 length, and width is 6mm, and the degree of depth is 6mm。
The depth and width of the described upper mould edge of a knife 2 are all consistent with upper die body notch 8;The degree of depth of the counterdie edge of a knife 5 is consistent with lower mold body notch 9, and the width of the counterdie edge of a knife 5 is more than the width of lower mold body notch 9。The hardness of the described upper mould edge of a knife 2 is more than the hardness of the counterdie edge of a knife 5。
The material of described upper die body 1 and lower mold body 4 is 45#, and the hardness of die body is 28HRC。In order to ensure edge of a knife intensity and service life, the material that performance is good and hardness is high need to be selected in edge of a knife position。
Time prepared by passenger car punching mold notch structure of the present invention, first processing the upper die body notch 8 of a width 6mm, degree of depth 6mm at described upper die body 1 edge of a knife position, be used for the upper mould edge of a knife 2 that freezes, the material of the upper mould edge of a knife 2 is SKD11, and edge of a knife hardness is 55HRC。Put in place according to 3D data mart modeling。
Then processing the lower mold body notch 9 of a width 6mm, degree of depth 6mm at described lower mold body 4 edge of a knife position, be used for the counterdie edge of a knife 5 that freezes, the material of the counterdie edge of a knife is H13, and edge of a knife hardness is 45HRC。The cooperation surplus of 0.05mm is stayed according to 3D data。
The counterdie edge of a knife 5 of the present invention leaves the cooperation surplus of 0.05mm on width when making, make between the mould edge of a knife 2 and the counterdie edge of a knife 5 as interference fit。During work, upper die body 1 and lower mold body 4 are both secured on milling train, and product fabric 3 is between upper die body 1 and lower mold body 4。Owing to the upper mould edge of a knife 2 is higher than the counterdie edge of a knife 5 intensity, anti-wear performance is good, during punch forming upper die body 1 move down die-cut lower mold body 4 time, the upper mould edge of a knife 2 can excise the use level of the reserved 0.05mm of the counterdie edge of a knife 5, make to become interference fits between the mould edge of a knife 2 and the counterdie edge of a knife 5, in guarantee, between the mould edge of a knife 2 and the counterdie edge of a knife 5, zero clearance coordinates, it is thus possible to make fabric successfully cut off, defines product 6 and product surplus 7。
Present configuration is applicable to die-cut class mould and cuts off the product effective profile of fabric retained product, saves follow-up high pressure waterjet operation, it is achieved that formed product and cut-out product profile carry out simultaneously。Decrease production operation, saved the production time, improve production efficiency。
