Abstract
The invention discloses a kind of Automobile Cover Drawing Die matched moulds gap detection method, comprise the following steps：1）The punch-pin of Automobile Cover Drawing Die, the working surface of cavity plate and spigot surface are scanned using laser or raster scanning equipment, the scan data of punch-pin, the working surface of cavity plate and spigot surface is obtained respectively；2）By in the scan data input scanning result processing software of punch-pin, the working surface of cavity plate and spigot surface, the virtual dough sheet of corresponding punch-pin, cavity plate working surface and spigot surface is generated in software, Virtual assemble matched moulds is then carried out；3）Matched moulds result is generated to the matched moulds gap size distribution of cloud atlas formula；It would know that the matched moulds gap distribution situation of punch-pin working surface and cavity plate working surface.The characteristics of the method has efficiency high, precision is high, the mated condition of actual punch and matrix working surface can intuitively be shown, for orthodox car covering drawing die, in finally assembling die trial, time-consuming, laborious, low production efficiency present situation is greatly improved, and to the repairing a die of covering drawing die, die trial has directive function.
Description
Technical field
The present invention relates to automobile die detection field, a kind of Automobile Cover Drawing Die matched moulds gap inspection is specifically related to
Survey method.
Background technology
In traditional Automobile Cover Drawing Die development process, after the completion of mold design and manufacture, it is necessary to by
Debugging modification repeatedly, can just obtain satisfied auto parts.The adjustment of drawing die be car panel die adjustment in most
It is difficult and troublesome.For automobile panel drawing die mould, thickness of slab gap is integrally uniform between typically requiring punch and matrix.It is logical
Frequently with the artificial brushing red lead powder on mould, by the experience of die trial pincers worker, by die trial, repair a die, again die trial, repair a die again
Cyclic process could be solved.This method not only reduces production efficiency, and the mould and die accuracy produced often do not reach it is pre-
The requirement of phase, can also lengthen the construction cycle of mould.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of Automobile Cover Drawing Die matched moulds gap detection side
Method, this method is simple to operate, using flexible, checking process rapidly and efficiently.
Technical scheme is as follows：
A kind of Automobile Cover Drawing Die matched moulds gap detection method, comprises the following steps.
1）Using laser or raster scanning equipment by the punch-pin of Automobile Cover Drawing Die, the working surface of cavity plate and
Spigot surface is scanned, and the scan data of punch-pin, the working surface of cavity plate and spigot surface is obtained respectively.
2）The scan data input scanning result of punch-pin, the working surface of cavity plate and spigot surface is handled in software, soft
The virtual dough sheet of corresponding punch-pin, cavity plate working surface and spigot surface is generated in part, Virtual assemble matched moulds is then carried out.
3）Matched moulds result is generated to the matched moulds gap size distribution of cloud atlas formula, you can know punch-pin working surface and cavity plate work
Make the matched moulds gap distribution situation in type face, especially know beyond the part of clearance control value.
Step 1）Described scanning refers to carry out multi-angled shooting using laser or raster pattern optical scanner, by multiple
Split obtains dough sheet data to picture in software.Described Laser Scanning Equipment is the HANDY that CREAFORM companies produce
SCANED equipment or the ATOS three-dimensional optical scanners of GEOM companies production.Described Laser Scanning Equipment scanning accuracy requirement reaches
Arrive：Form error is not more than 0.007mm, and sphere diameter error is not more than 0.018mm, and ball is not more than 0.031 mm away from error.
Step 2）Described scanning result processing software is that Vxelements softwares or TRITOP Professional are soft
Part.
It is preferred that, can be in step 2）After middle acquisition cloud atlas and data structure, coordinate net is directly generated, with 1:1 size pair
Mould in kind is answered, die surface in kind is projected to, testing result is obtained so that directly correspondence is in kind, so as to know that die clearance is opened up
Irrational position.
Relative to prior art, the present invention has the advantages that：
1st, in the design process of mould, die clearance can be quickly and efficiently checked, designing quality and level is improved.
2nd, Virtual assemble is carried out to mould in quality testing software and is fitted the actual conditions of punch and matrix work, carried out
Gap detection, can efficiently reduce the workload that manual brushing red lead powder carries out matched moulds test, time saving and energy saving, greatly improve and repair
Mould and die trial efficiency.
3rd, mould scrappage is effectively reduced, production cost is saved；Relative to after the completion of traditional design directly manufacture mould
Tool is compared, the method that provides of the present invention can reduce may caused by mould the workload such as do over again, reprocess, and can be in simulation
It was found that mistake or problem present in design, timely amendment design scheme, reduce mould scrappage, production cost is saved.
Brief description of the drawings
Fig. 1 is detection process schematic diagram of the invention.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1：
A kind of Automobile Cover Drawing Die matched moulds gap detection method, comprises the following steps：
1）Using laser or raster scanning equipment by the punch-pin of Automobile Cover Drawing Die, the working surface of cavity plate and
Spigot surface is scanned, and the scan data of punch-pin, the working surface of cavity plate and spigot surface is obtained respectively.
2）The scan data input scanning result of punch-pin, the working surface of cavity plate and spigot surface is handled in software, soft
The virtual dough sheet of corresponding punch-pin, cavity plate working surface and spigot surface is generated in part, Virtual assemble matched moulds is then carried out.
3）Matched moulds result is generated to the matched moulds gap size distribution of cloud atlas formula, you can know punch-pin working surface and cavity plate work
Make the matched moulds gap distribution situation in type face, particularly know beyond the part of clearance control value.
Step 1）Described scanning refers to carry out multi-angled shooting using laser or raster pattern optical scanner, by multiple
Split obtains unilateral data to picture in software.Described Laser Scanning Equipment is the HANDY that CREAFORM companies produce
SCANED equipment or the ATOS three-dimensional optical scanners of GEOM companies production.Described Laser Scanning Equipment scanning accuracy requirement reaches
