A kind of manufacturing process of adaptive tool heads of multiple spot integrated form using rotation progressive molding, includes the following steps：
(1) sheet metal blank to be processed is subjected to installation fixation；
(2) start numerically-controlled machine tool, tool heads rotate progressive motion according to the preset program of numerically-controlled machine tool；
(3) tool heads had not only rotated but also had applied plastic force to metal blank along track in motion process, processed
Tool heads can adaptively adjust vertical height with the variation of blank shape in journey；
(4) by successively rotating processing, Sheet Metal Processing is become required shape by the shape according to mold.
The method have the advantages that：It uses and is integrated with multiple adjustable points in a tool heads, it is bent to be used for shaped sheet
Face piece increases forming area, while still can be carried out according to different curve shape in the case where lathe power output is constant
Forming, the forming efficiency shaped than traditional single-point improve 40% or more, have saved manufacturing cost, improve processing quality, real
Existing plank low cost curve generating.During progressive molding tool heads can according to the variation of Sheet Metal Surface shape to be formed and from
Adjustment vertical height is adapted to, to improve sheet forming ability during plank progressive molding, principle is simple, easy to operate,
Sheet material forming precision can be effectively improved, improves forming efficiency, while reducing energy consumption.
The present invention be used for plate plastic deformation, for shaped sheet curved-surface piece have it is efficient, active area is big, stress
The defects of concentrating low effect, can effectively avoid corrugation, drawing crack in forming process, tool heads can during rotating progressive molding
Self-adapting adjusted positions can meet the processing of the plate shell class part of variously-shaped complexity.
