Description
Technical field
The present invention relates to progressive molding technical field, more particularly to a kind of rolling forming tool for progressive molding,
Device and method.
Background technique
Metal blank progressive molding technique is to be decomposed complicated threedimensional model according to a series of contour, by
Computer control forming tool is successively processed on two-dimensional surface.This method can process arbitrarily complicated in principle
Workpiece, and do not need mold.There is huge advantage for manufacture small lot, personalized new product.Compared to Sheet Metal Forming Technology, gradually
It is local plastic deformation into forming technology, makes full use of the deformability of plate, therefore can become second nature conventional ones technique cannot
The complicated shape of forming, have a wide range of applications potentiality in every field.Friction is prevalent in production practices, metal modeling
Property forming when in addition to general sliding friction feature and conventional mechanical transmission friction also make a big difference.It is asymptotic first
It is configured to local plastic deformation, tool heads and the small pressure caused on contact surface of web contact area are excessive, and lubricating oil film is fragile
It splits.Metal can generate certain heat during plastic deformation causes temperature to increase, and new gold continuously emerges in deformation process
Metal surface can all change original friction condition.Improve contact conditions to reduce frictional force, generally during progressive molding
Using lubricant, lubricant can be divided into liquid lubricant, lubricating grease and solid lubricant by its state.It is wherein most commonly used to be
Fluid lubricant.Lubricant improves the contact between forming tool and plate to a certain extent, improves the table of drip molding
Face quality.
Inventor's discovery has scholar to propose that rotation forming tool realizes the rotation of idler wheel in two mutually orthogonal directions,
Reduce the friction in forming process between forming tool and plate, but for the complex-shaped drip molding in practical application,
Complexity is contacted between forming tool and plate, flywheel moment size direction is uncertain, is difficult by rotary tool body around forming work
Tool arbor line is freely rotated, and guarantees that pivot center and the forming tool direction of motion are vertical always, the scheme that some scholars propose makes
Forming tool becomes non-centrosymmetric structure, but is not suitable for the high-speed rotating occasion of main shaft, and to Metal CNC Incremental Forming
The problems such as lathe need to coordinate feed speed and the speed of mainshaft when programming, and bring programming complicated, not easy to operate.
Therefore, that there are frictional resistance is big for existing forming tool and plate, because structure limitation can not be in larger use scope
The problem of interior wide-angle progressive molding for realizing plate.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of rolling forming tool for progressive molding, solutions
