Description
Technical field
The present invention relates to a kind of plate progressive molding devices, gradually more particularly, to a kind of plate based on superposition auxiliary material
Into forming device and method.
Background technique
The surface quality of part is to judge a key factor of progressive molding part forming quality.Jeswiet et al. exists
Document " Asymmetric incremental sheet forming. (Advanced Materials Research 2005,
6-8:35-58.) " in research discovery contour machining locus can leave the processing that not can avoid and eliminate in piece surface
Trace.Zhu et al. is in document " Spiral tool-path generation with constant scallop height
for sheet metal CNC incremental forming.(International Journal of Advanced
Manufacturing Technology, 2011,54:911-919) " it discusses between the helical tooth blade path of random geometry
Away from the calculation method to reach constant residual altitude, while discovery goes for lesser residual altitude and better surface matter
Amount is it is necessary to select lesser feeding depth, it means that processing parts costs more times.SkJoeDet et al. is in document
“Creating helical tool paths for single point incremental forming.(Key
Engineering Materials 2007,344:583-590.) " in disclose a kind of Surface Milling mould based on CAM software
Block generates the algorithm of helical tooth blade track (Conventional spiral tool path, CSTP), although spiral trajectory
The defect of cutter trade can be generated by avoiding contour line tracking, but still can not be solved between process time and surface quality
Problem.
The features such as many complicated sheet metal components have size big, and surface curvature change is big, local feature is obvious, using tradition
Contour or spiral collimation method, be easy to cause surface quality low, long processing time, rebound it is serious the problems such as, directly affect progressive
The application of forming in the industry.
For traditional progressive molding technique, there is inevitable lances between curring time and surface quality
Shield.It can reduce remained on surface height using lesser feeding depth, improve surface quality of workpieces, but process time can greatly
It is long.Opposite, if it is desired to improving progressive molding processing efficiency, the surface quality of part is inevitably deteriorated.This problem
It is particularly important when shaping part (such as automobile panel) of larger size.It is mentioned while not damaging surface quality of workpieces
The processing efficiency of high part just becomes extremely important, this is also quite to have for widening progressive molding technique in the application of industry
Meaning.
