Description
Technical field
The invention belongs to advanced material forming technique field, and in particular to a kind of synchronous rolling phase-adjustable of screw thread spline
Mould structure.
Background technology
With developing rapidly for auto industry and equipment manufacture, to steering axles, speed changer, planetary roller screw pair
The demand of middle screw thread spline coaxial element increasingly increases, and the requirement to such element precision and performance is gradually lifted.Tradition
Screw thread and spline coaxial element processing method based on machining, the shaping by stock removal screw thread is distinguished in different time sections
And spline, not only processing efficiency is low and cuts off metallic fiber influence part performance, by contrast screw thread rolling synchronous with spline
Forming technology has the advantages that production efficiency height, good forming quality, part screw thread and spline relative position are stable.
A kind of synchronous rollforming axial workpiece of screw thread spline is disclosed in the A of Publication No. CN 103084521 patent
Method, can in a rollforming simultaneously formation of parts different parts screw thread and spline flute profile.In order to ensure that screw thread is spent
The screw thread and spline of different rolling die rollformings can be connected in key synchronization rollforming, the thread segment in rolling front mold
The phase requirements before thread rolling and spline rolling are met simultaneously with spline segment.According to rolling front mold not isodont section phase
It is required that, a kind of synchronous rollforming mould structure of determination screw thread spline is disclosed in the A of Publication No. CN 103521665 patent
Method.The A of Publication No. CN 103521665 patent according to the number of starts of institute's rollforming part and rolling die,
Spline tooth number determines that the structure of two rolling dies under the structure of rolling die, certain situation is different, i.e., rolling die thread segment and
The relative position of spline segment is different.
But the thread segment and spline segment of rollforming mould connect firmly for rigidity at present, i.e. the thread segment and flower of rolling die
Key section can not realize that relative position is adjusted.For isodont phase section phase requirements need to be by rolling die before screw thread spline rolling
The rollforming that structure itself ensures, the structure of two rolling dies is different, i.e. the relative position of rolling die thread segment and spline segment
Difference is put, therefore must be individually designed with manufacturing for the different roll die of structure.Its rolling die can not be applied to screw thread
Thread form parameter is identical with spline teeth parameter, but the synchronous Roll-forming processes of the screw thread spline that phase requirements are different before rolling, rolling
Roll the poor universality of mould.Rolling die thread segment spline segment integrated design simultaneously, adds mould processing and manufacturing difficulty.From
And make die manufacturing cost, production cycle increase.
