Step S3：Backing plate is combined into the part before forming roll bending to carry out roll bending school shape.
In described step S2, after roll bending part flattening, roll bending part has multiple upper surfaces, with each upper surface
The plane parallel to roll bending part bottom surface at place be boundary by roll bending part partitioning into multiple part layer units.Be advantageous to this
Ensure that the thickness of each part layer unit keeps uniform, so that the plate thickness processed also keeps uniform, be advantageous to
Deformation of each backing plate when bending school shape is set to keep uniform, so as to be advantageous to improve the precision of school shape.
After described roll bending part flattening, if the upper surface of roll bending part includes and roll bending part bottom surface relative tilt
Inclined-plane, respectively with where inclined-plane summit parallel to roll bending part bottom surface plane and with where inclined-plane minimum point parallel to
The plane of roll bending part bottom surface is boundary by roll bending part layered shaping.
Described backing plate obtains by using Milling Process or the mode of increasing material manufacturing.
Described roll bending school shape carries out roll bending school shape by using roll bending lathe.
The present invention compared with prior art, has advantages below and beneficial effect：
By the present invention in that can be simulated with backing plate, bending to roll bending part is orthopedic, and it has scheme simple, easy to use
The advantages of, avoid, because duration, piece surface needed for the school shape brought using ultrasonic wave school shape are damaged serious phenomenon, making
This programme technique is simple, is advantageous to shorten the school shape time, and school shape efficiency can be improved.
