Description
Technical field
The invention belongs to high-strength boron steel stamping technology field more particularly to a kind of high-intensitive part thermoforming stamping dies
Manufacturing method.
Background technique
Mould development technique of traditional thermoforming stamping parts with softening energy-absorbing area, according to the geometry of room temperature auto parts
Shape calculates the geometry of part at a certain temperature by thermal coupling simulation analysis software, then calculates room temperature lower die
Have the geometry of forming blocks, carry out conventional room temperature machining with this geometry, complete after mold processes, to mold into
Heating of going is debugged, and there are more variable factors for whole process, and if thermal coupling simulation analysis model is inconsistent with reality, consideration is practical
Environment temperature in situation, humidity, wind-force etc.；The heat source transmission efficiency of simulation analysis is the same as variant in practice；Mold forming blocks
Material itself it is uneven, cause the expansion system of mold forming blocks inconsistent with thermal coupling simulation analysis mathematical model；Mold at
Heating source in type block, which is unevenly distributed, causes local swell increment inconsistent；Above-mentioned calculated result is approximation, by this mode
It is poor that production mold eventually leads to precision, needs largely to be debugged, product quality can not improve.
Summary of the invention
The purpose of the present invention is to solve above-mentioned technical problems, and provide a kind of high-intensitive part thermoforming stamping die
Manufacturing method reduces debug time to realize the accuracy for ensuring Mold Making precision and geometry.It is above-mentioned in order to reach
Purpose, technical solution of the present invention are as follows:
High-intensitive part thermoforming stamping die manufacturing method, comprising the following steps:
S1 carries out the design of traditional dies structure as needed, meanwhile, heat is carried out according to the geometry of part at high temperature
Coupling calculates；
S2, mold forming blocks are machined at a high temperature of constant, calculate data as the quasi- base of processing using thermal coupling；
S3 tests debugging to mold, compares the die face under high temperature with the otherness between design drawing, with thermal coupling
It is total to count according to as the quasi- base of detection；
S4, the mold after debugging enter formal production, calculate data as the quasi- base of production using thermal coupling.
Specifically, the mold is the mold for manufacturing a kind of high-strength boron steel auto parts.
Compared with prior art, the main body of beneficial effect of the high-intensitive part thermoforming stamping die manufacturing method of the present invention
It is present: to completely avoid calculating the Thermal couple analysis that complicated mold and mold forming blocks carry out, and only need to vapour
The monomer of vehicle part carries out its geometry at high operating temperatures of a Thermal couple analysis, and it is simple and have real to calculate mold
It with value, is machined at high temperature using mold, instead of the thermal coupling simulation analysis meter carried out to all mold general assembly bodies
It calculates, substantially increases the accuracy of manufacture of mold, simplify the development difficulty to mold design, shorten the design cycle, reduce mold tune
Number is tried, mould development fabrication cycle is shortened.
Detailed description of the invention
Fig. 1 is the flow chart of the embodiment of the present invention；
Specific embodiment
With reference to the accompanying drawing by the technical scheme in the embodiment of the invention is clearly and completely described, it is clear that retouched
The embodiment stated is only a part of the embodiment of the present invention, instead of all the embodiments.
Embodiment:
Shown in referring to Fig.1, the present embodiment is high-intensitive part thermoforming stamping die manufacturing method, comprising the following steps:
S1 carries out the design of traditional dies structure as needed, which is to manufacture a kind of high-strength boron steel auto parts
Mold；Meanwhile thermal coupling calculating is carried out according to the geometry of part at high temperature.
S2, mold forming blocks are machined at a high temperature of constant；Data are calculated as the quasi- base of processing using thermal coupling.
S3 tests debugging to mold, compares the die face under high temperature with the otherness between design drawing；With thermal coupling
It is total to count according to as the quasi- base of detection.
S4, the mold after debugging enter formal production, calculate data as the quasi- base of production using thermal coupling.
When using the present embodiment, hot operation state when mold is heated to debugging and batch punching press use carries out mechanical
Processing, swell increment caused by avoiding mold materials uneven is inconsistent, and temperature transmits the height of temperature caused by speed, heats source distribution
The problems such as swell increment caused by uneven is inconsistent, the processing and fabricating temperature of mold forming blocks is equally debugged completely, also and finally
It is the same to produce temperature in batches, ensure that the accuracy of die clearance and geometry, greatly reduce the die debugging time, so that
The quality pass rate of final stamping products improves.
The present embodiment completely avoids calculating the Thermal couple analysis that complicated mold and mold forming blocks carry out, and
It only needs to carry out the monomers of auto parts its geometry at high operating temperatures of Thermal couple analysis, calculates mold letter
Singly and there is practical value, is machined at high temperature using mold, instead of the thermal coupling carried out to all mold general assembly bodies
Simulation analysis calculates, and substantially increases the accuracy of manufacture of mold.Simplify the development difficulty to mold design, shorten the design cycle,
Die debugging number is reduced, mould development fabrication cycle is shortened.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
