Description

Mold freedom curved surface flexible polishing machine
Technical field
The present invention relates to the polishing machine field, especially a kind of mold freedom curved surface flexible polishing machine.
Background technology
In recent years, the development of mold manufacturing industry is swift and violent day by day, and involvement aspect is increasingly extensive.Such as automobile, aviation, boats and ships, toy, electronic product, civilian household electrical appliances etc., almost do not have can't be obtained.In mould was made, the surface of mold cavities such as plastics mould, compression mod, forge mould was complicated, the ratio height that free form surface is shared, processing technology difficulty maximum, very high to its surface roughness requirement, thus must carry out the die cavity polishing, to improve the service life of mould.And at present, finishing the method that shape processing adopted mainly is milling and electric processing method, and these methods often can not satisfy processing request, must carry out back processing for this reason, generally adopts manual polishing to carry out the back to process, and will consume many man-hours and expense.To the analysis showed that of some forging die production costs, present expense more than 30% all expends in the processing of back (mainly being manual polishing).At present, have only the big mould enterprise of minority to adopt full-automatic polisher lapper.Its reason is mainly automatic polishing machine and costs an arm and a leg, and realizes that the control ratio of predetermined polishing purpose is difficult, and only is applicable to the uniform polish of plane or simple surface, so rate of return on investment is low.Polishing accounts for 30%~50% of entire die manufacturing time its process time as one important procedure of mold cavity processing, and its cost accounts for 5%~30% of complete manufacturing cost, and polishing has become the bottleneck in the die manufacture.
