Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
Notice, the structure of this specification institute accompanying drawings depicted, ratio, size etc., all only in order to coordinate the disclosed content of description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the adjustment of the modification of any structure, the change of proportionate relationship or size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still drop in the scope that the disclosed technology contents of this utility model can be contained.Simultaneously, in this specification cited as " on ", D score, "left", "right", " centre " and " one " etc. term, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
With reference to Fig. 2, in vehicle side drawing and moulding process, first plate 4 is placed on lower punch 2 and blank holder 3, and then upper cavity die 1 moves downward and is pressed between upper cavity die 1 and blank holder 3 by plate 4.Then upper cavity die 1 continues to move downward, and upper cavity die 1 and blank holder 3 clamp plate 4 and move downward, and plate 4 will to contract, and final plate 4 shapes on lower punch 2.As it is shown on figure 3, this utility model provides a kind of vehicle side R0 feature crest line place quadruple board platform stepwise die face modeling structure, including: include the upper cavity die 1 for vehicle side drawing and lower punch 2；The die face of described vehicle side drawing R0 feature crest line place's drawing upper cavity die 1 includes ground floor step 11 from the top down, the first withdrawing pattern sidewall 12, and the first fillet 13；It is provided with second layer step 14 between described ground floor step 11 and described first withdrawing pattern sidewall 12；Described first fillet 13 is connected with the second withdrawing pattern sidewall 15；The die face of described vehicle side drawing R0 feature crest line place's drawing lower punch 2 is provided with the stepped structure 21 matched with described second layer step 14 and the first recessed circle 22 matched with described first fillet 13, and described stepped structure 21 is corresponding with described second layer step 14 position；Described first recessed circle 22 is corresponding with described first fillet 13 position.
Described ground floor step 11 was drawing the second fillet, and described drawing the second radius of corner of crossing is 8mm～20mm, sees Fig. 3.
Described quadruple board platform rank are connected by the 3rd fillet with ground floor step 11, and described 3rd radius of corner is 20mm～30mm.Described quadruple board platform rank height is 5mm～30mm.Described quadruple board platform rank draft angle is 25 °～50 °.Described quadruple board platform rank are connected by the 4th fillet with described first withdrawing pattern sidewall 12, and described 4th radius of corner is 6mm～20mm, sees Fig. 3.
Described first withdrawing pattern sidewall 12 offsets 1mm～5mm to normal direction.Or described first withdrawing pattern sidewall 12 open angle is 0 °～5 °, sees Fig. 3.
Under described the first side wall, fillet maximum radius is 50mm.
For different Automobile Body Modelings, these parameters also correspond to different numerical value.It is presented above the numerical range of each parameter, concrete numerical value can be obtained by iterative optimization method.
Pass through iterative optimization method, above parameter area (crossing drawing the second fillet, second layer step 14 draft angle, second layer step 14 height, the 3rd fillet, the 4th fillet, skew sidewall amount, sidewall angle of release amount and 12 times fillets of the first withdrawing pattern sidewall), for eliminating cracking and wrinkling, is optimized by optimization aim.First ground floor step 11 great circle cambered surface substitutes, and crosses drawing amount and does little；Greater than after drawing the second fillet, the side wall surface below ground floor step 11 is carried out angle of release or skew, for reducing postorder shaping amount, angle of release and offset distance are as far as possible little, progressively amplifying numerical value moulding, maximized fillet makes second layer step 14 shape, notes preventing from interfering with product.Optimal solution can be found out, namely solve cracking and a wrinkling difficult problem simultaneously.
In sum, this utility model provides vehicle side R0 feature crest line place quadruple board platform stepwise die face modeling structure, and this die face modeling structure is provided with second layer step 14 between described ground floor step 11 and described first withdrawing pattern sidewall 12.First, doing ground floor step 11, be namely exaggerated original product fillet, it is possible to the directly place's of avoiding cracking, reduction can substantially reduce, when ground floor step 11 is sufficiently large, it is possible to resolve drawing is ftractureed；Described second layer step 14 is it can be avoided that because described ground floor step 11 causes wrinkling stack phenomenon, and the problem that the integer quantity of postorder increases, and ensures that moulding is also close to product-forming such that it is able to solve cracking and a wrinkling difficult problem.So, this utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for restriction this utility model.Above-described embodiment all under spirit of the present utility model and category, can be modified or change by any those skilled in the art.Therefore, all art have all equivalence modification or changes that usually intellectual completes under the spirit disclosed without departing from this utility model with technological thought, must be contained by claim of the present utility model.
