Description
Technical field
The invention belongs to automobile die punching press field, specifically refer to a kind of mould structure moulding process for shaping.
Background technology
On Vehicles Collected from Market, along with automobile quantity increases, the speed of a motor vehicle improves, and traffic accident increases.It is more and more important that vehicle safety seems, one of the most apparent important measures are that automobile component will significantly strengthen.
Energy shortage, seriously polluted, being doomed requirement automobile reduces oil consumption, saves the energy, and an important method that reduces oil consumption is to alleviate automotive dead weight, current research to automobile fuel consumption and deadweight relation shows: automobile fuel consumption is linear with deadweight, as automotive dead weight reduces by 10%, in the situation that other conditions are constant, at least can make automobile fuel consumption reduce by 5%.
How can reduce tare and can strengthen bus body strength again, a lot of people can expect the application of high-strength steel, can be along with the application of high-strength steel, and high strength can make Plasticity Decreasing, formability meeting variation, and along with the raising of yield strength can cause area distortion and spring-back effect.
Therefore high-strength plate is just higher to the requirement of mould, and especially a good structure can be considered springback compensation from source, in the debugging in later stage and entrucking problem, has all reduced greatly workload.Although a lot of mould structures allow to control springback capacity, most springback compensation and springback capacity are all that experience and numerical simulation draw artificially, cannot solve root problem.The application that how could promote high-strength steel can improve the precision of vehicle body again, mould producer is found for the U-shaped part mold developing of high-strength plate by current most of main frame manufacturer all specific (special) requirements, require mould producer must possess exploitation high strength steel board mold rich experience, especially resilience and compensation aspect thereof there are is the advantage of making, need to have software application that AUTOFOPM, PAM etc. are skilled as supporting for meticulous resilience simulation.
Such as in threshold stiffener support plate, the material of use is B410LA, belongs to high-strength plate material series.The forming parts degree of depth is larger, extremely easily resilience after flange moulding, according to production technology and mouldability more fixed scheme be four order techniques, the first order is blanking and punching, the second order flange, the 3rd order flange moulding, the 4th order shaping.This technique is technical scheme conventional in existing Sheet Metal Forming Technology.The mould of operation is taked is that two flange of part are parallel with shaping, by sidewall shaping, forms, and this structural approach is comparatively general, but poor to the control accuracy of springback capacity, often cannot be from basic solution resilience, as shown in Figure 1.
Prior art should can be described as scheme and the mould structure of all high-strength plate product resilience shaping process, comparatively common and traditional.According to on-the-spot comparison in kind, find that prior art scheme is comparatively first-selected not obvious to resilience shaping effect.Clearance control too greatly cannot be eliminated resilience, can't resolve root problem, and the too tight words in gap can cause flanging and restriking partly to make part occur serious plucking and weigh wounded, the therefore more difficult control of assurance to degree.
This kind of reshaping structure figure often can not control resilience thoroughly, thus cause still having the existence of resilience in sheet metal component entrucking process, so precision can not get effective assurance.And U-shaped of the of this sort degree of depth often easily there will be the phenomenon getting stuck with mould to occur after shaping, therefore the feeding style of getting in process of production has larger difference, is not easy to production operation, and operability and security are all existed to certain drawback.
Summary of the invention

The specific embodiment
Describe by the following examples technical scheme of the present invention in detail, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
As shown in Figures 2 and 3, a kind of shaping mould shaping structures technique, including the first operation is blanking and punching operation; The second operation is overturning process; The 3rd operation is flange molding procedure; The 4th operation is trimming;
The technical program has been carried out certain change and optimization mainly for the mould structure of said structure and similar above-mentioned Training system and the feeding style of getting of part, mainly exactly the resilience shaping of this part will be positioned over after part half-twist in mould 2 by stressed the changing into of sidewall, by the pressing of upper/lower die profile, part is carried out to shaping, by the stressed bearing up-down force that changes in original left and right, the material mode that picks and places of part parallelly picks and places with counterdie profile (from the side) by changing into perpendicular to counterdie profile.The flange profile of described part is parallel with upper/lower die profile.
The material of described part is high duty metal sheet material, such as B410LA series etc., but is not limited to this.
In the present embodiment, threshold stiffener support plate 1 with a vehicle, material is the B410LA of high-strength plate material series, and the forming parts degree of depth is larger, in the easy resilience of flange, according to technique and mouldability comparison consistent with Fig. 1 part be four order techniques, the first order is blanking and punching, the second order flange, the 3rd order flange moulding, the 4th order shaping, for the 4th order technique shaping mould 2 structures of this part.
This part pick and place material direction, two flange profiles are parallel with upper/lower die profile, it is more accurate that this structure can make shaping control springback capacity, and in production process, also improved operability and security, thereby further promoted precision and the production efficiency of sheet metal component.
More original mould structure and to pick and place material mode known, originally shaping be subject to force direction and placing part mode, shaping mould structure after improvement makes the material mode that picks and places of part and is subject to force direction F as shown in Figure 3, both sides are stressed because the factor restrictions such as structure and part shape cause the stressed meeting in part side well below Fig. 3, and it is dead that existing technology shaping is not easy pier, also just mean that die reshaping is not in place, resilience cannot be eliminated at all, and thereby if power is excessive easily causes part because the punch surface of the too dark card of flange counterdie, production gets stuck not easy to operate, and Fig. 3 itself is subject to force direction consistent with gravity direction, the easy pressing of part, resilience eradicating efficacy better and pickup from the side comparatively easy from security and operability.
