On the basis of can also be：Buffer unit, the buffer unit are provided between the lathe spindle 10 and the hold assembly
It is fixedly connected with the lathe spindle 10 and hold assembly respectively.So, because the material of Ferrite Material is frangible, clamping
Cheng Zhong, buffer unit effectively mitigates the hard contact of hold assembly and blank 9, and when blank 9 is clamped, buffer unit is to clamping force
Enter row buffering, it is ensured that structure is not destroyed and efficient and high-quality turnery processing after material die mould.Further preferred technology
Scheme is：The buffer unit includes guide rod 1 and spring 2, and one end of the guide rod 1 is plugged in one end of the lathe spindle 10
Center position, the spring 2 is set in the other end outside of the guide rod 1, and the other end of the guide rod 1 is plugged in the folder
Hold the center position of part one end.So, when hold assembly is clamped, hold assembly clamps blank 9, and blank 9 is being received
After power, spring 2 buffers the clamping force of blank 9, and lathe spindle 10 when rotated, drives guide rod 1 to be rotated, so as to drive blank
9 carry out turning.Further preferred technical scheme is：The hold assembly include front end inner sleeve 3 and rear end inner sleeve 5, it is described before
End inner sleeve 3 fixes the other end for being set in the guide rod 1, and the rear end inner sleeve 5 is fixed and is set in the one of the tailstock center 7
End, the blank 9 is folded between the front end inner sleeve 3 and the rear end inner sleeve 5.So, blank 9 is folded in front end inner sleeve 3
In the middle part of rear end inner sleeve 5, blank 9 is contacted with front end inner sleeve 3 and rear end inner sleeve 5, blank 9 is clamped by frictional force.
Turning machining device after Ferrite Material die mould of the invention, as shown in figure 1, in previously described technical scheme
On the basis of can also be：The hold assembly outside is slidably arranged with the centring elements for carrying out centering to blank.
So, compared with traditional fixed form, during clamping blank 9, the central shaft of blank 9 is difficult to be directed at the central shaft of lathe, leads to
The central shaft that centring elements cause the central axial alignment lathe of blank 9 is crossed, blank 9 is centrifuged in effectively prevent process
Power and cause clamp unstable and blank flexural deformation.Further preferred technical scheme is：The centring elements include front end
Overcoat 4 and rear end overcoat 6, the front end overcoat 4 and the rear end overcoat 6 are slidably set in the He of front end inner sleeve 3 respectively
At the blank 9, the rear end inner sleeve 5 and the link position of the blank 9.So, the front end overcoat 4 and the rear end overcoat
6 are slidably set at the front end inner sleeve 3 and the blank 9, the rear end inner sleeve 5 and the link position of the blank 9 respectively,
Front end overcoat 4 and rear end overcoat 6 are felt relieved to blank 9, blank 9 are effectively ensured with lathe in coaxial, it is ensured that crudy.
Turning machining device after Ferrite Material die mould of the invention, as shown in figure 1, in previously described technical scheme
On the basis of can also be：Tailstock center 7, the tailstock center 7 are provided between the hold assembly and the pneumatic tailstock 8
One end be slidably plugged in the center position of pneumatic tailstock 8, and be connected with the pneumatic tailstock 8, the other end is inserted
It is located at the center position of affiliated rear end inner sleeve 5.So, lathe tailstock is slidably arranged on lathe guide rail 11, realizes blank 9
Position coarse adjustment, by setting tailstock center 7, the flexible of tailstock center 7 is realized by pneumatic tailstock 8, can effectively to blank 9
The fine setting of position so that positioning is more accurate, meanwhile, fine setting can adjust the suffered clamping force of blank 9, be prevented effectively from blank
9 damage.
The present invention also provides the method for turning after a kind of Ferrite Material die mould, comprises the following steps：
S1:Microwave ferrite material turning tool is installed；
S2:Pressure P, lathe tool feed speed f, the back engagement of the cutting edge a of pneumatic tailstock 8 are setp；
S3:By the clamping of blank 9 in the middle part of hold assembly；
S4:Start Pneumatic tailstock and clamp blank 9, be processed；
S5:After machining, stop lathe, unclamp Pneumatic tailstock, remove workpiece.
So, assembly working, sets pressure P, lathe tool feed speed f, the back engagement of the cutting edge a of pneumatic tailstock 8p, by microwave iron
The clamping of blank 9 after ferrite die mould starts Pneumatic tailstock and clamps blank 9 in the middle part of hold assembly, is processed, and processes
Cheng Hou, stops lathe, unclamps Pneumatic tailstock, removes workpiece, in machining blanks 9, blank 9 is folded in the hold assembly
Portion, after lathe starts, lathe spindle 10 is rotated, because hold assembly is fixed on lathe spindle 10, blank 9 with clamping
Part frictional connection, lathe spindle 10 drives blank 9 to rotate together so that lathe tool carries out turning to blank 9, effectively prevents routine
Installation way destroys the structure of blank 9 or clamping is not tight, effectively reduces difficulty of processing, improves processing efficiency.Relative to prior art
For this have the advantage that：Solve after microwave ferrite material die mould that the strength of materials is low, be difficult to clamping, turnery processing waste product
Rate problem high, realizes the efficient and high-quality turnery processing after the material die mould.
The pressure P of pneumatic tailstock 8 and each Cutting parameters n, f, apSetting be determined by experiment, it is necessary to follow following original
Then：

More than radial cutting force, i.e.,：2μPA2>Fx
μ-confficient of static friction in formula
The contact area of A- front ends inner sleeve 3 or rear end inner sleeve 5 and blank 9
Fx- along the radial cutting force of the radial direction of blank 9
(2) to prevent capping or press-bending blank 9, the pressure that the end face of blank 9 can bear need to be more than the thrust of pneumatic tailstock 8
With axial cutting force sum, i.e.,：FEnd>PA+Fy
F in formulaEndThe pressure that the end face of-blank 9 can bear
Fy- along the axial cutting force of turning direction of feed
Fx、FyRelation with each Cutting parameters is：
C in formulaFx、CFy- influence coefficient, its size is relevant with experiment condition
- back engagement of the cutting edge a0To cutting force Intrusion Index
- amount of feeding f is to cutting force Intrusion Index
- design conditions and experiment condition are when different to the correction factor of cutting force
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
