Abstract
A phase-adjustable die structure for synchronously rolling threaded splines comprises a rotary drum. An inner hole of the rotary drum is connected with a power shaft of a rolling device. A rolling die spline section is installed at one end of the outer portion of the rotary drum, and a rolling die thread section is installed at the other end of the outer portion of the rotary drum. The rolling die spline section is fixedly connected with the rotary drum through a first end cap. The rolling die thread section is matched with the rotary drum through a sliding bearing on a second end cap. A phase adjusting structure is arranged between the rolling die spline section and the rolling die thread section. A one-way separation mechanism is arranged between the rotary drum and the rolling die spline section or the rolling die thread section. Since the rolling die spline section and the rolling die thread section are independent, adjustment of the relative locations of the rolling die spline section and the rolling die thread section is achieved through the phase adjusting structure, and the phase-adjustable die structure can adapt to different thread shapes and spline shapes only by installing the corresponding rolling die spline section and the corresponding rolling die thread section through replacement. The phase-adjustable die structure for synchronously rolling threaded splines is simple in structure, easy to manufacture and high in universality.
Description
Technical field
The invention belongs to advanced material forming technique field, be specifically related to a kind of screw thread spline and synchronize
Rolling phase-adjustable mould structure.
Background technology
Along with developing rapidly of auto industry and equipment manufacture, to steering axles, variator,
In planetary roller screw pair, the demand of screw thread spline coaxial element increases day by day, and to such zero
The requirement of part precision and performance gradually promotes.Traditional screw thread and the processing side of spline coaxial element
Method, based on machining, distinguishes this screw thread of shaping by stock removal and spline, no in different time sections
But working (machining) efficiency is low and cuts off metallic fiber and affects part performance, by contrast screw thread and spline
Synchronize Roll-forming processes and have that production efficiency is high, forming quality is good, part screw thread and spline phase
The advantage stable to position.
The patent of Publication No. CN 103084521 A discloses a kind of screw thread spline and synchronizes rolling
The method rolling into shape axial workpiece, can in a rollforming simultaneously formation of parts different parts
Screw thread and spline flute profile.In order to ensure that screw thread spline synchronizes different rolling dies in rollforming
The screw thread of rollforming and spline can be connected, and thread segment and spline segment in rolling front mold are wanted
Meet the phase requirements before thread rolling and spline rolling simultaneously.According to rolling front mold difference tooth
Type section phase requirements, discloses one and determines spiral shell in the patent of Publication No. CN 103521665 A
Stricture of vagina spline synchronizes the method for rollforming mould structure.Publication No. CN 103521665 A
Patent determine according to institute's rollforming part and the number of starts of rolling die, spline tooth number
The structure of rolling die, under certain situation, the structure of two rolling dies is different, i.e. rolling die spiral shell
Stricture of vagina section is different with the relative position of spline segment.
But thread segment and the spline segment of rollforming mould are that rigidity connects firmly at present, i.e. rolling die
The thread segment of tool cannot realize relative position adjustment with spline segment.For before screw thread spline rolling not
The rollforming that isodont phase section phase requirements need to be ensured by rolling die structure self, two rollings
The structure rolling mould is different, i.e. rolling die thread segment is different with the relative position of spline segment, because of
This must individually designed and manufacture for the roll die that structure is different.Its rolling die cannot be fitted
Identical with spline teeth parameter for form of thread parameter, but the spiral shell that before rolling, phase requirements is different
Stricture of vagina spline synchronizes Roll-forming processes, the poor universality of rolling die.Rolling die screw thread simultaneously
Section spline segment integrated design, adds mould processing and manufacturing difficulty.So that Making mold becomes
Originally, the production cycle increases.
