(3.2) it runs, process the other positions in addition to U-shaped pressing plate；
(3.3) it adjusts U-shaped pressing plate to assemble, mating part L2=0.1L, it is undressed at U-shaped pressing plate in procedure of processing (3.1)
Part；
(3.4) common pressing plate clamping is used, only part remains at cleanup step (3.3).
Beneficial effects of the present invention:
(1) design, production and use of fork-shaped pressing plate realizes the maximum elementary object of clamping working (finishing) area for the first time, first
Minimal amount of surplus is not purged at remaining pressing plate after secondary clamping processing, remaining is processed in place, and it is more to reduce same web
Add up position error caused by secondary clamping processing；
(2) design, production and use of fork-shaped pressing plate, to greatest extent to being fixed at T-type slender beam reinforcing rib,
The problem of avoiding in the poor place's web positioning of intermediate intensity, causing web deformation, dimension overproof, realizes web total quality
The target of raising；
(3) cooperate fork-shaped template and method mentioned in the present invention, numerical control processing T-type slender beam that need to only move pressing plate 1-2
It is secondary that whole processing can be completed, improve overall processing efficiency；
(4) cooperate fork-shaped template and method mentioned in the present invention, when the elongated web of numerical control processing T-type, web deformation
Measure it is small, allow and knife or cross and cut situation and can almost ignore, avoid and manually adjust the operation that tool length compensation guarantees web thickness,
Improve overall processing efficiency.
