Abstract
The invention provides a riveting method. The riveting method includes the steps that first drive force is adopted for driving a riveting heat to move toward a rivet; extrusion force borne by the front end of the riveting head is obtained; whether the extrusion force is larger than a preset value or not is judged, and if not, the first drive force is continuously used for driving the rivet; if yes, the first drive force is changed to be larger second drive force to drive the rivet. In comparison with the prior art, according to the riveting method, the riveting process is more accurate due to the fact that the different levels of drive force are arranged to drive the rivet to move, riveting accuracy is improved, and the situation that the riveting accuracy is reduced due to damage to the rivet is avoided.
Description
Technical field
The present invention relates to riveting technology field, relate in particular to a kind of clinching method.
Background technology
Existing riveting machine is driving die in rivet moving process, the driving force that drives die to move all remains unchanged, simultaneously in order to guarantee that the follow-up punching press for rivet completely all arranges great driving force, yet before die contacts with rivet, die is mobile speed under driving compared with large driving force, rivet is very easily pushed by die and bend distortion, cause rivet cannot carry out follow-up riveted joint, cause riveted joint inefficiency, severe patient causes die extruding to treat riveting piece, causes immeasurable economic loss.
Therefore, be necessary to propose a kind of new clinching method to address the above problem.
Summary of the invention
The invention provides a kind of clinching method that precision is high of riveting.
Compared with prior art, clinching method provided by the present invention, it comprises:
Adopt First Driving Force to drive die to move towards rivet;
Obtain die extruding force that front end bears;
Judge whether described extruding force is greater than preset value, if not, continue to use First Driving Force to drive rivet; If so, changing First Driving Force is the second larger drive force rivet.
As a further improvement on the present invention, described " adopt First Driving Force drive die move towards rivet " step is included in First Driving Force is provided in very first time interval.
As a further improvement on the present invention, described " obtaining die extruding force that front end bears " step is included in the mean value that obtains die extruding force that front end bears in second time interval.
As a further improvement on the present invention, described " judging whether described extruding force is greater than preset value " step is included in extruding force in the 3rd time interval and is greater than preset value.
As a further improvement on the present invention, described the 3rd time interval is 0.5 millisecond.
As a further improvement on the present invention, described " change First Driving Force be the second larger drive force rivet " step was included in the 4th time interval that the second driving force is provided.
As a further improvement on the present invention, described very first time interval is greater than described second time interval.
As a further improvement on the present invention, described very first time interval is greater than described the 4th time interval.
Compared with prior art, clinching method provided by the present invention, moves by the drive force die of different stage is set, and makes riveted joint process more accurate, has improved riveted joint precision, avoids the damaged riveted joint precise decreasing causing of rivet.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing relevant of the present invention in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the flow chart of clinching method in one embodiment of the invention.
The specific embodiment
Below with reference to each embodiment shown in the drawings, describe the present invention.But these embodiment do not limit the present invention, the conversion in the structure that those of ordinary skill in the art makes according to these embodiment, method or function is all included in protection scope of the present invention.
Shown in ginseng Fig. 1, clinching method provided by the invention, by the driving force of different stage is set, has improved the precision of riveted joint.
Wherein, clinching method provided by the present invention, it comprises:
Adopt First Driving Force to drive die to move towards rivet;
Obtain die extruding force that front end bears;
Judge whether described extruding force is greater than preset value, if not, continue to use First Driving Force to drive rivet; If so, changing First Driving Force is the second larger drive force rivet.
Concrete, described " adopting First Driving Force to drive die to move towards rivet " step is included in First Driving Force is provided in very first time interval.
Concrete, described " obtaining die extruding force that front end bears " step is included in the mean value that obtains die extruding force that front end bears in second time interval.
Concrete, described " judging whether described extruding force is greater than preset value " step is included in extruding force in the 3rd time interval and is greater than preset value.
Especially, described the 3rd time interval is 0.5 millisecond.
In the present embodiment, described " change First Driving Force be the second larger drive force rivet " step was included in the 4th time interval that the second driving force is provided.
In the present embodiment, described very first time interval is greater than described second time interval.
In the present embodiment, described very first time interval is greater than described the 4th time interval.
Compared with prior art, clinching method provided by the present invention, moves by the drive force die of different stage is set, and makes riveted joint process more accurate, has improved riveted joint precision, avoids the damaged riveted joint precise decreasing causing of rivet.
Be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present invention; they are not in order to limit the scope of the invention, all disengaging within equivalent embodiment that skill spirit of the present invention does or change all should be included in protection scope of the present invention.
