Embodiment 1,
As shown in Figure 8, described step is same as described above, and its difference is, the angular velocity that described first-stage semi-finished product rotates with
The relation of the speed of preforming one spinning roller process is:
, 350rpm >=w>=250rpm, v unit is mm/s；
Shown by research, when rustless steel blank rotates, the quality of its spinning and angular velocity of rotation and mould schedule speed
Coordinating relevant, when rotary speed is relatively low, such as 250rpm, mould schedule speed is the most unsuitable too high, because schedule speed is too high, and rotation
Rotary speed is too low, easily makes radially producing of blank excessive pull power during spinning, causes on blank retaining part and enters film
Occurring on position trickle pullling fold, the most this fold should not be found by naked eyes, but in use, pleat occurs
No matter the position of wrinkle is below normal value with in hardness in toughness, affects workpiece quality.If rotary speed is too high, mould simultaneously
Too low also can the generation die workpiece of tool schedule speed is pullled, and also can pull apart workpiece under extreme condition, if rotating speed and mould simultaneously
Tool coordinates not in place, and during its process, motor there is also idle running phenomenon, consumes electric energy.By repetition test, to gather
Data are fitted and emulate, and inventor have found equilibrium point, the in the case quality of work piece production in the case of above formula
The highest, when i.e. producing, workpiece is minimum by pullling the destruction of power, and the power consumption of motor is minimum simultaneously.Final inventor determines ought
When blank rotating speed is 300rpm, module fabricating quality is optimal.
Embodiment 2
As it is shown in figure 9, described step is same as in Example 1, its difference is, for the first time spinning blank rotate angular velocity with
The relation of the speed of preforming two spinning roller process is:
, 350rpm >=w>=270rpm, v unit is mm/s；
Principle is similar to Example 1, and its difference is, after the process of first time spinning, the edge of work is trimmed to half
Ball shape, due to workpiece not directly by the position of hard force, therefore the stress-bearing capability of spinning blank to be significantly stronger than one for the first time
Level semi-finished product, the rotating speed of blank can significantly improve, when rotating speed is same, and as 300rpm, module fabricating quality is optimal.
Embodiment 3
As shown in Figure 10, described step is same as in Example 3, and its difference is,
The angular velocity that described second time spinning blank rotates with the relation of the speed of molding spinning roller process is:
,350rpm≥w>=300rpm, v unit is mm/s；
Along with the final molding of blank, its stress-bearing capability reaches peak, i.e. carries out rotating speed and mould process speed during final molding
Degree can point to maximum, when rotating speed reaches 350rpm, it is possible to makes the spinning semi-finished product of best in quality of the present invention, this portion
Part surface flatness is the highest, and stress-bearing capability is the strongest, and plastic property is best.
