The crown band attaching process is various in types, the width of the crown band is different, manufacturers of the conventional tire need to compile different control programs aiming at different process tables, the programming workload is very large, all process requirements cannot be met, and users are difficult to test special crown band process outlines. If a scheme that multiple regions share one set of program is adopted, manual calculation is needed to set the required cap ply outline, although the flexibility is enough, the requirement on workers is higher, more time is needed, and when the width of the cap ply provided by the previous process is deviated, the cap ply cannot be found in time and can not be accurately adjusted.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a method for quickly calculating various crown band process profiles, which can be suitable for different crown band winding profile processes, automatically calculate the initial position of the crown band and the step pitch and the turn number of the crown band in each winding interval, and reduce the time of manual calculation and debugging.
To achieve the above object, the present invention provides a method for rapidly calculating a plurality of crown band process profiles, comprising a crown band and a belt drum for winding the crown band, comprising the steps of:
the method comprises the following steps: determining a center position of a belt drum; selecting a winding mode of the crown band;
step two: allowing custom winding but not automatic calculation, manually setting the technological parameters of 8 intervals for winding the cap strip according to the technological requirements, rotating and translating the belt drum according to the manually set technological parameters of 8 intervals, and winding the cap strip to form a cap strip technological outline;
step three: if the custom winding is not allowed and the automatic calculation is allowed, only the total fitting width, the width of the crown band strip and the overlapping amount are input; the starting position of the belt drum and the technological parameters of 8 intervals for winding the cap strip are automatically calculated through a program, and the belt drum rotates and translates according to the automatically calculated technological parameters of 8 intervals to wind the cap strip to form a cap strip technological outline.
Further, in step three, once the width of the crown band tape is deviated, the width of the crown band tape can be re-input manually, and the starting position of the belt drum and the process parameters of 8 intervals for winding the crown band tape can be automatically re-calculated and corrected by the program. By the design, the problem that the width of the crown band provided by the previous process cannot be accurately adjusted in time usually when the width of the crown band deviates can be quickly solved.
The winding mode comprises a symmetrical winding mode and a self-defined mode; the symmetrical winding mode is that 8 intervals are wound symmetrically left and right at the central position of the belt drum, the symmetrical winding mode comprises three types of tiling winding, S-shaped winding and discontinuous winding, and under the symmetrical winding mode, the process parameters of the 8 intervals and the initial position of the belt drum are automatically calculated by a program; the custom mode is that the crown band strip is wound in 8 intervals symmetrically or asymmetrically, and under the custom mode, the technological parameters and the technological parameters of 8 intervals and the initial position of the belt drum need to be manually set. For the three symmetrical winding modes, the invention adopts automatic calculation to calculate the initial position of the belt drum and the step pitch and the winding turns of the cap strip in 8 intervals so as to realize the rapid calculation of the process profile of the cap strip layer of tiling winding, S-shaped winding and discontinuous winding; and for the self-defining mode, the starting position of the belt drum and the step distance and the winding number of the crown band strip in 8 intervals are manually input, and automatic calculation cannot be carried out, so that a user can automatically compile various irregular crown band winding processes.
The total attaching width is the total width of a belt ply on a belt drum for laminating, winding and attaching crown tape strips, and the overlapping amount is the overlapping amount of two adjacent crown tape strips; the 8 intervals are divided into intervals 1-8 by the total width of the belt ply; the interval 1 to the interval 4 and the interval 5 to the interval 8 are symmetrical with the central position of the belt drum; the technological parameters of 8 intervals are the step distance of axial movement of the belt drum of each interval and the winding number of turns of the rotary winding crown band strip; the step pitch is the axial displacement of the belt drum per rotation. Namely, the crown band strip is wound and stacked on the belt layers in the interval 1-8 to form the crown band layer process outline through the rotation control and the axial stepping control of the belt drum.
In a symmetrical winding mode, the edge winding width or/and the middle winding width are automatically and symmetrically divided by taking a central position as a central line in the total laminating width; the overlapping amount of the crown band strips in the edge winding width is the edge overlapping amount, and the overlapping amount of the crown band strips in the middle winding width is the middle overlapping amount in the middle winding width; if the edge overlapping amount is not consistent with the middle overlapping amount, setting numerical values of the edge winding width and the middle winding width, and simultaneously setting numerical values of the edge overlapping amount and the middle overlapping amount; if the side overlapping amount is consistent with the middle overlapping amount, the value of the winding width of the side is set to be 0, the side overlapping amount does not work, and the value of the middle of the overlapping amount needs to be set. In this design, the side winding width and the side overlapping amount are not set if the overlapping amounts of the belt upper edge to the middle crown band winding are the same for the segmental winding.
In the tiling winding, the crown band strips are continuously attached from the edges of the belted layer, and the intervals 1-4 and the intervals 5-8 are in mirror symmetry with the central position;
