Detailed description of the invention
Embodiment one
Fig. 1 is the schematic flow sheet of the resilience correction processing method embodiment of beam class mould of the present invention, wherein, beam class mould is mainly for the manufacture of such as chassis frame, roof rail, front beam, front and back collision prevention girders and some buttress braces, and these beam classes play the part of skeleton and booster action in automotive body structure; The structure section of above-mentioned beam class, in " U " or " several " font, can be straight beam or curved beam, designed by body structure.As shown in Figure 1, the beam class die processing method of the present embodiment can comprise:
101, according to parameter determination mould shape face, the shape face parameter of preset beam class workpiece, and the first beam class mould is made according to described mould shape face parameter by equipments machining die;
Wherein, in the technological design stage of mould, resilient nature and the performance characteristic of the workpiece adopting this Mold Making can be analyzed in advance by cae analysis software, and consider the adjustment that the later stage may need to carry out repeatedly to mould, so can comprehensively according to cae analysis result and later stage shaping, when mould structure design, necessary allowance is retained to mould, carry out secondary operations to allow the mould later stage or repeatedly process.In mould structure design, it is also conceivable to repeatedly the reasonability etc. of the intensity of processing mold, work stability under loading and fixed form.
In this step, after structural design is carried out to mould, when can make the first beam class mould according to mould shape face parameter, allowance is retained to the first beam class mould.Wherein, this first beam class mould is equivalent to the mould of initial fabrication.
102, by the first beam class Mold Making first test piece;
Wherein, during by first beam class Mold Making the first test piece, pincers worker is only responsible for lapping-in (not affecting workpiece flow), does not do the adjustment of work status; Suppress laser cutting after workpiece, reduce the workpiece deformation that laser cutting causes, in order to avoid affect follow-up workpiece compensation work as far as possible.
103, the mould shape face parameter after being compensated by Springback Analysis equipment;
Wherein, the Springback Analysis equipment of this step can be computer, this computer is mounted with the analysis software such as such as CATIA.The shape face parameter of the first test piece in 102 is obtained by Springback Analysis equipment, three-dimensional specifically can be adopted to adopt a little or white light scanning method process first test piece, generate the some cloud file of corresponding first test piece, this cloud file is equivalent to the simulation work status of the first test piece, comprising the shape face parameter of the first test piece.This step is equivalent to the quality state after to workpiece lapping-in and feeds back.
Concrete, CATIA process points cloud file can be utilized, the shape face parameter of the shape face parameter of the first test piece and preset beam class workpiece (i.e. original product workpiece) is compared, obtains workpiece springback capacity; And according to described workpiece springback capacity, the mould shape face parameter of the correlation module instrument in CATIA to the first beam class mould is utilized to carry out springback compensation, mould shape face parameter after being compensated, can suppress resilience preferably with the mould making the mould shape face parameter after adopting this compensation make.
In this step, mould that can be corresponding to the mould shape face parameter after compensation carries out cae analysis, the deformation behaviour of prediction springback compensation place workpiece.
Wherein, it should be noted that, the cae analysis that above-mentioned the present embodiment adopts and the effect that CATIA analyzes are different.Concrete, CAE software can the shaping situation of Predicting and analysis punching parts, prediction judge moulding change after part trend of rebound, it can also be analyzed the wrinkling of die face and break; But CAE software analysis resilience is qualitative is not quantitative, and can only predict approximate trend, its result is available on anticipation trend, but inaccurate in precision, gathers part point cloud feedback after still will leaning on actual debugging mould.CATIA software is 3D sculpting software, is mainly used in design elements, and function has curved surface, entity, the operation of some cloud, motion analysis, large-scale assembling, electronics wiring, magnetic field analysis of electric field etc., and the present embodiment adopts curved surface and the points cloud processing function of CATIA.
104, according to the mould shape face parameter after compensation, the second beam class mould is made by equipments machining die;
Wherein, adopt the mould shape face parameter after compensation and make in the second beam class mould, owing to being carry out die adjustment according to the result of springback compensation, adjustment is comparatively accurate, accurately can control the Production design of mould; And be according to die adjustment after shape face parameter, control equipments machining die and carry out Mould Machining, also the accuracy rate of Mold Making is further increased, relative to manual manufacture and the adjustment mode of prior art, substantially increase the accuracy rate of Mold Making, provide significant conservation die adjustment time and mould production cost, save the duration.
In addition, in this step, add man-hour carrying out adjustment to mould, be utilize the Mould Machining surplus retained in 101, mould can be reused, save cost.
105, by the second beam class Mold Making second test piece;
106, judge that the shape face parameter of the second test piece and preset beam class workpiece meets workpiece Eligibility requirements, if so, then continue execution 107; Otherwise, return 103, and continue repeatedly to perform described 103-106, until when the shape face parameter of test piece and preset beam class workpiece meets workpiece Eligibility requirements, determine final mould shape face parameter;
107, determine final mould shape face parameter, make final beam class mould according to final mould shape face parameter.
Wherein, according to above-mentioned process, through several take turns adjustment after, the mould can producing qualified workpiece can be obtained; Such as, generally through about three-wheel die adjustment, perfect condition can be reached.Above-mentioned final mould shape face parameter is the mould shape face parameter of corresponding qualified workpiece; Described workpiece Eligibility requirements specifically can set according to concrete production and service condition.
Adopt the mould that the method for the present embodiment is produced, its qualification rate is approximately 92%; Relative to 84% qualification rate of common die processing method of the prior art, the qualification rate of the workpiece of Mold Making is obviously increased substantially, significantly reduces the defects such as the resilience of workpiece.
The resilience correction processing method of the beam class mould of the present embodiment, springback compensation is carried out by the mould shape face parameter of workpiece springback capacity to mould obtained according to Springback Analysis device analysis, and make new mould by equipments machining die according to the mould shape face parameter after springback compensation, make when making mould, not only because Springback Analysis device analysis workpiece springback capacity makes the parameter of Mold Making institute foundation comparatively accurate, and owing to making mould by equipments machining die, make relative to artificial experience of the prior art, make the processing of mould more accurate, the design of accurate control mould and production, greatly save the production time of mould, reduce the cost of manufacture of mould.
