Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the production process schematic diagram of present invention trial-production vehicle side.
As shown in Figure 1, the production method of trial-production vehicle side provided by the invention, includes the following steps:
S1:Analysis modeling is analyzed, simulated and is modeled by software according to product data, and drawing route is formulated; S2:It draws Prolong, according to the drawing route that step S1 is formulated, drawing is carried out to plate by drawing die, obtains drawn component;S3:Once cut It cuts, first time shape cutting is carried out to drawn component using five axis laser cutting machine devices;S4:Flange, by flanging die to shape Drawn component after cutting carries out flange;S5:Secondary cut carries out the using five axis laser cutting machine devices to the drawn component after flange Secondary shape is cut, and completes hole cutting, obtains vehicle side part;S6:Side shaping, by side shaping mould to vehicle side part Side shaping is carried out, side shaping is completed to obtain gusset product.
Specific implementation is as follows:
Middle CAE is set forth below and refers to computer-aided engineering, CAD refers to CAD.
Receive product data moulding, carry out product-forming signature analysis, in conjunction with product feature, formulates Sheet Metal Forming Technology route, Art shapes scheme is cooked up, the verification of being formed property is analyzed by simple CAE software.It was found that product there are the problem of, together When, for features formation problems such as moulding in product, product problem feedback is proposed to client, Sheet Metal Forming Technology is formulated, according to CAE Software analysis result carries out mold data structural modeling.The purpose that client is manufactured experimently, exactly in order to verify design result, with And mass production in future there may be the problem of, by automobile panel part punching press, the trial-manufacturing process such as be welded, and problem is cleared up, in the future Being smoothed out for vehicle mass production, paves the way.
Formulate drawing route, the selection for drawing direction, it is desirable that forming is abundant, eliminates skid wire, and truncation Line is not exposed, Must not there are corrugation, thick neck and cracking phenomena, make drawing depth difference minimum as possible, to reduce the unevenness of material flowing and deformation distribution Even property ensures there is good contact condition when punch-pin starts drawing with drawing blank, starts punch-pin and drawing blank when drawing Contact area is big, and contact surface should be close proximity to center of die;Each radius of corner preferably larger, curve form is in drawing direction Actual grade answer it is more shallow, everywhere uniform depth some, shape is simple as possible and changes gentler etc. as possible, drawing direction The big contact area of punch-pin and blank, rational binder surface shape and pressure-pad-force is set to keep each position drag uniform of binder surface suitable as possible It spends, reduce drawing depth, opening fabrication hole and process-cut etc.;The drawbead of reasonable design can be taken, justified using larger mold Angle makes the measures such as rationally of punch-pin and cavity plate gap.It is simulated in conjunction with CAE software, such as result display cracking, corrugation, rigidity is sliding The Testing index for moving line meets the requirement of trial-production product, can export the moulding data of analysis, be carried out in CAD software It quickly reads in, modeling reaches and analyzes the almost the same of state, flash mould may be implemented, put into production, and ensures client node And quality requirement, it is controlled by analysis result, reduces debugging cycle, lower manufacturing operation cost.
Drawing carries out drawing by drawing die to plate, and drawing die carries out mold system using the material of zinc-containing alloy Make, Zn-base alloy fusing point is low, and cooling velocity is fast, and stress release is uniform, and casting deformation amount is small, and casting cycle is short, material casting Part hardness is in HB140 or so, after processing is completed, can meet product material thickness 1.5mm hereinafter, Kang La Qiang Du≤340MPA, Produce the trial-production task of the Pi components parts for assembly of a machine of Liang≤200;The material of gusset drawing die zinc-containing alloy compares relatively normal cylinder iron HT300, 6 days or so can be saved casting cycle, material cast Brinell hardness is less than HT300 materials 100 or so, and roughing and essence may be implemented Processing can carry out punching press debugging production, and HT300 materials also need to carry out semifinishing, can reduce time processing in this way, save Cost-saving and period.More meet production requirement of the main engine plants to current quickly exemplar;The material of zinc-containing alloy, mold anti-corrosive properties are more Good, later stage preservation management is at low cost;Zinc-containing alloy(ZAS)Material can reuse, the only weight of loss 7% or so can be with Substantially reduce casting cost.
Fig. 2 is that Computer ancillary works software analysis result of the embodiment of the present invention reaches qualified drawn component schematic diagram; Fig. 3 is to obtain drawn component schematic diagram after the blank drawing of trial-production vehicle side in the embodiment of the present invention.Comparison diagram 2 and Fig. 3, drawing The drawn component that process obtains can reach the requirement of design.
Cutting carries out shape cutting using five axis laser cutting machine devices to drawn component, and outside plate product carries out pre- allowance cutting, After product data product side is deployed into cutting data face, trimming length direction is expanded into 5mm, i.e., pre- allowance is 5mm;Product Corner pack edge, to prevent overturning process from causing the more material in part, on the corner pre- allowance is 2mm to cutting line.
Drawn component after radium-shine cutting is carried out flange by flange using flanging die.Drawn component is determined using positioning pin Position, determine flange direction, the direction of motion and flange flange, stile of flange cavity plate are consistent, the direction of motion of flange cavity plate and Flange basal plane is vertical.
Product after flange is carried out side shaping by side shaping using side shaping mould.Determine side perfect square to the whole sliding block in side The direction of motion and product it is consistent, the direction of motion and lower die basal plane of cavity plate are vertical.Vertical binder, side can be used in side shaping type Flange needs to simplify setting using sliding block inclined wedge etc., and the period is short, manufacturing cost bottom.By simple hand loose tool to gusset part part Negative angle position carry out shaping.
In conclusion the production method of trial-production vehicle side provided by the invention, completes to model by software analysis mode, The R&D cycle of soft mode part is shortened, the Mold Making period is short, compact structure, can greatly reduce the volume weight of mold, drop Low manufacturing cost shortens assembly and debugging cycle.
Although the present invention is disclosed as above with preferred embodiment, however, it is not to limit the invention, any this field skill Art personnel, without departing from the spirit and scope of the present invention, when can make a little modification and it is perfect, therefore the present invention protection model It encloses to work as and is subject to what claims were defined.
