In present embodiment, described muller axle sets one end of muller to tilt upward and is located on column, in order to muller
It is fixed and positioned.In practical application, muller axle 20 can set with horizontal plane or be set with plane-parallel
Put.
The structure of muller 21 structure of processing part needed for is manufactured, such as can set groove in its outer peripheral face
Or it is raised, to be correspondingly formed raised and groove on the surface of workpiece.Groove or projection quantity can be one or
A plurality of, shape can be with identical, can also be different.
Left roller and right roller are the cylinders that can be rotated around own axes, and outer peripheral face is settable to make parts to be processed
The quantity of the groove or projection of inner peripheral surface shaping, groove or projection can be one or a plurality of, shape can with identical,
Can also be different.
Roller quantity（That is the quantity of processing stations）It is configured according to production needs, is not limited to two in present embodiment
It is individual.In the present embodiment, roller rocker arm shaft is provided on base, can be set in practical application according to the setting direction of muller axle
In corresponding suitable position.
The course of work of the present invention（By taking the station of left side as an example）For：
Muller 21 keeps rotary motion with muller axle 20 under the driving of muller axial brake device；
When processing starts, left roller 30 is in the position away from muller 21, and annular workpieces blank is enclosed on left roller 30, and upper left is auxiliary
Helping wheel 4, lower-left auxiliary wheel 29, both are in close to each other or contact position；
In process, left roller rocking arm 26 drives left roller 30 gradually in the driving lower swing of left roller rocking arm drive device 3
Close to muller 21, be enclosed in the process annular workpieces blank on left roller 30 first with upper left auxiliary wheel 4, lower-left auxiliary wheel
29 contacts, each auxiliary wheel imposes appropriate pressure to annular workpieces blank, it is ensured that annular workpieces blank will not be on left roller 30
Arbitrarily mobile, in this process, the rightmost side of annular workpieces blank inwall is abutted against on left roller 30, the He of upper left auxiliary wheel 4
Certain inhibition is played in the motion of the left roller 30 of 29 pairs of lower-left auxiliary wheel；As left roller 30 continues to move to muller 21,
Upper left auxiliary wheel 4, lower-left auxiliary wheel 29 are progressively separated from each other in the case where holding is contacted with annular workpieces blank；When annular work
The contact point of part blank and two auxiliary wheels is crossed after the two auxiliary wheel lines of centres, and two auxiliary wheels are close to each other again, at this
During, the leftmost side of annular workpieces blank inwall is close on left roller 30, and two auxiliary wheels to annular workpieces blank by applying
Plus-pressure to left roller 30 so that play certain impetus, until annular workpieces blank is contacted with muller 21, the band of muller 21
Rotating ring shape workpiece blank is rotated around left roller 30；Annular workpieces blank drives left roller 30 to rotate, and left roller 30 continues close to stone roller
Wheel 21 simultaneously oppresses annular workpieces blank, its section is diminished, and diameter becomes big；Each auxiliary wheel keeps connecing all the time with annular workpieces blank
Touch, when annular workpieces blank diameter becomes big, upper left auxiliary wheel 4, lower-left auxiliary wheel 29 are also separated from each other；When annular workpieces blank is straight
When footpath reaches preset value, the left counter motion of roller 30, upper left auxiliary wheel 4, lower-left auxiliary wheel 29 are also acted in each automatic drive device
Lower to be disengaged with annular workpieces, process is completed.
Upper left auxiliary wheel 4, lower-left auxiliary wheel 29 not only act as the effect of radial positioning in process, prevented also from ring
Unwanted deformation occurs for shape workpiece blank, improves the machining accuracy of workpiece.
The above described is only a preferred embodiment of the present invention, being not limited to the present invention.It is any to be familiar with this specialty
Technical staff, do not depart from the technology of the present invention design on the premise of, make some changes using the technology contents of the disclosure above
The technical scheme obtained with improvement, still within the scope of the present invention.
