Description
Technical field
The present invention relates to vehicle exterior cladding element mold more particularly to a kind of vehicle exterior cladding element mold machining manufactures.
Background technique
Otherwise the visible surface of vehicle exterior cladding element damages automobile the defects of being not allow for ripple, type face injustice, be recessed
Appearance.For these defects, general analysis reason and the measure taken are:
1. increasing mold pressure-pad-force.The surface quality defects such as ripple, the uneven, recess in type face generate on part, are flanging
Caused by power is insufficient, it is possible to increase mold pressure-pad-force is eliminated；But complicated part is because of its asymmetry, in draw-texture process
In deformation everywhere it is uneven, if increasing pressure-pad-force, the position that part deformation may be made violent is cracked, and deforms small portion
There is corrugation again in position.
2. adjusting the radius of corner of cavity plate.It for corrugation, can suitably reduce die entrance to eliminate, but the angle R is controlled
System often empirically, needs debugging for a long time just to can solve corrugation problem.
3.A face data is converted from the programming processing of moulding to the end by multiple format, and data precision is inadequate, in conversion
Data are easy to appear error in the process.
Summary of the invention
In order to solve the problems in the prior art, the present invention provides a kind of vehicle exterior cladding element mold processing and manufacturing sides
Method.
The present invention provides a kind of vehicle exterior cladding element mold machining manufactures, comprising the following steps:
S1, the data format using high standard, outer covering piece A face data precision are 0.001mm, and different software is converted
Uniform format is * .stp format；
S2, the die face technology using fining, guarantee according to the gap for needing to adjust upper and lower mould of part different location
The quality of part；
S3, using hyperfine mirror finish and detection, finishing is processed using 0.2mm step pitch after fire, the table of mirror finish
In Ra, " 0.2um, the non-face the A region stride control of benchmark mould is in 0.5mm, and revolving speed is not less than 10000 turns, shaping for surface roughness control
Benchmark mould uses the strategy of fiery post-processing, and same mold is completed to process on same a machine tool, secondary clamping elder generation light bottom surface, in
Start to be heat-treated after milling, be heat-treated as laser quenching, starts semifinishing twice after the completion of heat treatment, finally finished,
Direction is parallel crest line direction, and the face A machining accuracy is controlled in ± 0.03mm or less；
S4, light method is pushed away using standardized pincers worker, is combined with mirror finish, under the conditions of mirror finish, mold is pushed away
Light cancel hard oil stone, light is pushed away using the dedicated foam oilstones of outside plate more than 220 mesh, push away light direction be it is crisscross, finally use
Sand paper essence is thrown, and polishing direction is vehicle body direction.
As a further improvement of the present invention, in step sl, the continuous tolerance of A face data G0 is 0.001mm.
The beneficial effects of the present invention are: through the above scheme, improving the machining accuracy of outer covering piece, improving outer covering piece
Surface quality greatly shortens the debugging mold time.
Detailed description of the invention
Fig. 1 is the flow chart of vehicle exterior cladding element mold machining manufacture of the present invention.
Specific embodiment
The invention will be further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of vehicle exterior cladding element mold machining manufacture, comprising the following steps:
1) data format of high standard, the continuous tolerance of A face data G0 are increased to 0.001mm by traditional 0.005mm.System
One modeling software, product design software, mold design software, machining prgraming software format transformation be * .stp. reduce difference
Error caused by software format is converted.
2) the die face processing method of superfinishing refinement, guarantees according to the gap for needing to adjust upper and lower mould of part different location
The method that later period debugs is advanceed to and is embodied on the process data of front by the quality of part.Increase to the debugging of later period pincers worker enough
Adjustment amount, convenient for pincers worker carry out lapping-in mold.
3) hyperfine mirror processing method and detection.Increased to 3 times by 2 times traditional finishing.Increase primary hyperfine
Processing.Finishing using fire after 0.2mm step pitch processing (mirror finish, surface roughness control Ra " 0.2um).The non-A of benchmark mould
Region stride control in face is not less than 10000 turns in 0.5mm, revolving speed.Shaping benchmark mould must also be added using the strategy of fiery post-processing
Work scheme is formulated referring to Drawing Die, and last step pitch is 0.3mm, and same mold needs to complete processing on same a machine tool
(secondary clamping needs first light bottom surface).As shown in table 1, start to be heat-treated after middle milling, preferential recommendation laser quenching, heat treatment is completed
After start semifinishing 1 and 2, last finishing, direction is parallel crest line direction.The face A machining accuracy is controlled in ± 0.03mm
(three coordinate measurements are placed 24 hours before measurement in three coordinate room constant temperature) below.
Table 1
4) standard pushes away light method, and under the conditions of mirror finish, mold pushes away light and cancels hard oil stone, more than 220 mesh
Outside plate dedicated foam oilstone pushes away light, and it is crisscross for pushing away light direction.It is finally thrown with sand paper essence, polishing direction is vehicle body direction.
A kind of vehicle exterior cladding element mold machining manufacture provided by the invention establishes new outer covering piece mold and adds
Data format of the work manufacturing process by high standard, the die face technology of fining, hyperfine mirror finish data and detection data
And standardized pincers worker pushes away light method.
A kind of vehicle exterior cladding element mold machining manufacture provided by the invention, has the advantage that
1) outer covering piece A face data precision is improved to 0.001mm, has unified different software format transformation * .stp format.
2) the die face processing method of superfinishing refinement, provides help to pincers worker die debugging lapping-in below, preferable to guarantee
The quality of part.
3) hyperfine mirror processing method redefines processing heat treatment method, heat treatment time, processes step pitch, knife
Tool revolving speed and feeding redefine.Processing method and testing requirements and method are defined.
4) mold of standard pushes away light method, combines with mirror finish.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
