(3.3) U-shaped pressing plate assembling is adjusted, mating part L2=0.1L is undressed at U-shaped pressing plate in procedure of processing (3.1)
Part；
(3.4) common pressing plate clamping is used, cleanup step (3.3) place only has part residual.
Beneficial effects of the present invention：
(1) design of fork-shaped pressing plate, make and use, realize the maximum elementary object of clamping working (finishing) area first, it is first
Minimal amount of surplus is not purged at a remaining pressing plate after secondary clamping processing, and remaining is processed in place, reduces same web many
The accumulative position error that secondary clamping processing is caused；
(2) design of fork-shaped pressing plate, make and use, to greatest extent to being fixed at T-shaped slender beam reinforcement,
Avoid in the poor place's web positioning of intermediate intensity, cause web deformation, the problem of dimension overproof, realize web total quality
The target of raising；
(3) method mentioned in fork-shaped model and the present invention is coordinated, the T-shaped slender beam of digital control processing need to only move pressing plate 1-2
It is secondary to complete all processing, improve overall processing efficiency；
(4) method mentioned in fork-shaped model and the present invention is coordinated, during the T-shaped elongated web of digital control processing, web deformation
Amount is small, allow and knife or cross and cut situation and can almost ignore, it is to avoid manually adjust the operation that tool length compensation ensures web thickness,
Improve overall processing efficiency.
