Abstract
The invention discloses a method for detecting die assembly clearances of an automobile covering part drawing die. The method comprises the following steps: 1, scanning the work profiles and the guide surfaces of a male die and a female die of the automobile covering part drawing die by laser or optical grating scanning equipment, and respectively obtaining the scanning data of the work profiles and the guide surfaces of the male die and the female die; 2, inputting the scanning data of the work profiles and the guide surfaces of the male die and the female die into scanning result processing software, generating virtual patches corresponding to the work profiles and the guide surfaces of the male die and the female die in the software, and then, carrying out virtual assembly die assembly; 3, generating die assembly results into a cloud picture type size distribution of the die assembly clearance, and obtaining the distribution condition of the die assembly clearances of the work profile of the male die and the work profile of the female die. The method has the characteristics of being high in efficiency and high in precision, can visually demonstrate the actual matching condition of the work profiles of the male die and the female die, is greatly improved compared with the time waste, labor waste and low production efficiency conditions of a traditional automobile covering part drawing die during final assembly and die trial, and has guidance functions on the repair and the trial of the covering part drawing die.
Description
Technical field
The present invention relates to automobile die detection field, specifically relate to a kind of Automobile Cover Drawing Die matched moulds gap detection method.
Background technology
In traditional Automobile Cover Drawing Die development process, after Design of Dies and manufacture complete, need, through debugging amendment repeatedly, just can obtain satisfied auto parts.The adjustment of drawing die is the most difficult and troublesome in car panel die adjustment.For automobile panel drawing die mould, between General Requirements punch and matrix, thickness of slab gap is evenly overall.Be typically employed in artificial brushing red lead powder on mould, by means of the experience of die trial pincers worker, by die trial, repair a die, die trial again, the cyclic process that repairs a die again could solve.This method not only reduces production efficiency, and the mould and die accuracy produced often does not reach the requirement of expection, also can lengthen the construction cycle of mould.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of Automobile Cover Drawing Die matched moulds gap detection method, the method be simple to operate, applying flexible, checking process rapidly and efficiently.
Technical scheme of the present invention is as follows:
A kind of Automobile Cover Drawing Die matched moulds gap detection method, comprises the following steps.
1) adopt laser or raster scanning equipment the punch of Automobile Cover Drawing Die, the working surface of die and spigot surface to be scanned, obtain punch, the working surface of die and the scan-data of spigot surface respectively.
2) scan-data of the working surface of punch, die and spigot surface is inputted in scanning result process software, generate the virtual dough sheet of corresponding punch, die working surface and spigot surface in software, then carry out Virtual assemble matched moulds.
3) matched moulds result is generated the matched moulds gap size distribution of cloud atlas formula, the matched moulds gap distribution situation of punch working surface and die working surface can be known, especially know the part exceeding clearance control value.
Scanning described in step 1) refers to and adopts laser or raster pattern optical scanner to carry out multi-angled shooting, by plurality of pictures in software split obtain dough sheet data.Described Laser Scanning Equipment is the HANDY SCANED equipment of CREAFORM company production or the ATOS three-dimensional optical scanner of GEOM company production.Described Laser Scanning Equipment scanning accuracy requires to reach: 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 apart from error.
Step 2) described in scanning result process software be Vxelements software or TRITOP Professional software.
Preferably, can in step 2) in obtain cloud atlas and data structure after, directly generate coordinate net, with the corresponding mould in kind of the size of 1:1, be projected to die surface in kind, obtain testing result so that directly correspondence is in kind, thus know that irrational position is offered in die clearance.
Relative to prior art, the present invention has the following advantages and good effect:
1, in the design process of mould, die clearance can be checked quickly and efficiently, improve designing quality and level.
2, in quality testing software, Virtual assemble is carried out to mould and the actual conditions of matching punch and matrix work, carry out gap detection, effectively can reduce the workload that manual brushing red lead powder carries out matched moulds test, time saving and energy saving, greatly improve and repair a die and die trial efficiency.
3, can effectively reduce mould scrappage, save production cost; After completing relative to traditional design, direct mfg. moulding die is compared, the workloads such as the mould that method provided by the invention can reduce to cause is done over again, reprocess, and mistake or the problem of existence in design can be found in simulation, timely amendment design scheme, reduce mould scrappage, save production cost.
