Description
Technical field
The present invention relates to cold punching die processing technique field, be specifically related to a kind of automobile support arm module processing technology.
Background technology
Automobile support arm module similar to Figure 4, its structure mainly comprises bulge position, radian position, flange position, described bulge position is positioned in the middle part of the one end at described radian position, described flange position is positioned at both sides, described radian position, about described radian position or fore-and-aft direction there is the radian be bent upwards.
In the prior art, above-mentioned automobile support arm module processing technology comprises following key step successively: a), drawing: unprocessed monoblock sheet material is processed to form bulge position, radian position and part flange position by Drawing Die; B), trimming: the excess waste of the level without drawing is excised by edger; C), flange: the sheet material of horizontal position remaining after trimming is processed to form complete flange position by flange die.
The deficiency that above-mentioned technique exists is: first, realization is carried out in order to enable trimming operation, flange position cannot be once-forming, can only by the first forming section flange position of drawing, the shaping at residue flange position will be completed by overturning process again after completing trimming operation, this technique inevitably causes automobile support arm module to form folding line at flange position, and the mechanical strength therefore for automobile support arm module can have a significant effect, and mechanical strength is the important quality attribute of this part; Secondly, because the drawing amplitude at bulge position is larger, cause the ensemble average thickness that bulge part material thickness is starkly lower than automobile support arm module, cause bulge position to become the bottleneck of automobile support arm module mechanical strength, significantly limit raising and the improvement of automobile support arm module processing quality.
Summary of the invention
The object of the present invention is to provide a kind of automobile support arm module processing technology, the automobile support arm module flange position shown in Fig. 4 can be effectively avoided to produce folding line in formed machining, and the drawing amplitude at bulge position can be reduced significantly, thus make bulge part material thickness can not be starkly lower than the ensemble average thickness of automobile support arm module, to improve the overall mechanical strength of automobile support arm module, namely improve the processing quality of automobile support arm module significantly.
To achieve these goals, the technical scheme that the present invention proposes is:
A kind of automobile support arm module processing technology, comprises the steps:
A), blanking: unprocessed monoblock sheet material is processed the excess waste after excision shaping in advance by blanking die;
B), drawing: step a) products obtained therefrom is processed to form bulge position by Drawing Die, and described Drawing Die is without flanging Drawing Die;
C), be shaped: step b) products obtained therefrom is processed to form radian position and flange position by finishing die.
Above-mentioned technique adopts the blanking operation of the first step to instead of the operation of carrying out trimming in prior art after drawing again, compared with prior art, there is not folding line in flange position, thus the folding line that effectively prevent flange position in prior art is on the impact of workpiece mechanical strength; In addition, by first blanking, technical gaps or fabrication hole can be set, combination can improve the mobility in material processing effectively without flanging drawing again, thus significantly reduce the extension amplitude of material in drawing operation, namely the object that bulge part material thickness can not be starkly lower than the ensemble average thickness of automobile support arm module is achieved, thus improve the overall mechanical strength of automobile support arm module, improve the processing quality of automobile support arm module.
As optimization of the present invention, in above-mentioned automobile support arm module processing technology, the blanking die of described step a) and the Drawing Die of described step b) are a symmetrically arranged mould two pieces, are provided with connection between two pieces; And also comprise dicing process between described step b) and described step c).
The blanking die of described symmetrical structure and Drawing Die contribute to increasing work efficiency on the one hand, once complete the processing of two pieces product, contribute to ensureing workpiece uniform stressed simultaneously, thus improve the processing characteristics of mould and the quality of workpiece.The object of dicing process is the two pieces separation of products that links together and deburring, so that the carrying out of follow-up flange operation.
As further optimization of the present invention, in above-mentioned automobile support arm module processing technology, the Drawing Die of described step b) comprises upper bolster, die shoe, die, punch, holding pad, described die is fixedly arranged on described upper bolster, described punch is fixedly arranged on described die shoe, and described holding pad is positioned at described punch surrounding and is movably set in die shoe; Described holding pad upper surface is provided with multiple step, and the height of described step is that a material is thick.
Described structure can make rapidoprint have sufficient mobility, to reduce extension amplitude, contributes to the deformation direction of controlled working material when stressed simultaneously, thus prevents workpiece fold or out of shape in drawing operation process.
Optimize further again, in above-mentioned automobile support arm module processing technology, in the drawing sequence of described step b), between described bulge position and flange position, unprocessed inner side, be provided with transition arcs.The described bulge position of workpiece and flange position, unprocessed inner side are in drawing step, partial span amplitude can be made excessive without radian transition, causing material unnecessary in shaping overturning process to produce fold, effectively can overcome the problems referred to above by setting up described transition arcs process structure.
In sum, automobile support arm module processing technology provided by the present invention, effectively can improve the overall mechanical strength of automobile support arm module, namely improve the processing quality of automobile support arm module.
