Description
Technical field
The present invention relates to the Machining Technology field, relate in particular to a kind of clinching method.
Background technology
Riveted joint be welded as two kinds of modes that are connected the polylith plate that industry is known, wherein, riveted joint be exactly utilize rivet will by riveting parts be linked together on-disconnectable connection, the existing application of history for a long time in building structure and mechanical manufacturing field.During riveted joint, earlier rivet is inserted by in the riveted holes of riveting parts, utilize the die of riveting machine to carry out punching press or rolling, thereby accomplish riveted joint so that rivet produces deformation to rivet.
At present; Existing riveted joint requires fast and riveted closely; Therefore riveting machine must apply several tonnes the power of weighing, because the needed sizable power of rivet driver, riveting machine must be configured to quite big and heavy; Artificial uncontrollable riveted joint process, so the numerical control riveting machine just becomes the main flow selection.
Yet existing riveting machine does not have good grasp for the riveted joint process, especially before and after snap head of riveting machine contacts with rivet, does not reasonably judge; Therefore cause the riveted joint process that the workmen can't clear and definite riveting machine, simultaneously after die carries out punching press or rolling completion to rivet, can't automation stop; The uncontrollability that often causes the process of riveting; Cause the riveted joint failure, influence the ordinary production of workpiece, even produce security incident.
Therefore, be necessary to propose a kind of new clinching method and change the problems referred to above.
Summary of the invention
The present invention provides a kind of clinching method that can accurately control the riveted joint process.
For realizing the foregoing invention purpose, the invention provides a kind of clinching method, this method comprises the steps:
S301: riveting machine is provided and is furnished with the riveting parts of rivet, said riveting parts is placed the station of riveting machine;
S302: start riveting machine, move towards rivet, and measure force value, and the distance values of die and station of said die front end to control said die;
S303: when die forefront pressure value changed, the spacing of reading die and station was first spacing;
S304: when the distance values of die and station was second spacing, the control die stopped to move to finish riveted joint;
As further improvement of the present invention, said S302 step specifically comprises: after starting riveting machine, the control riveting machine fixedly riveting parts in station.
As further improvement of the present invention, said S303 step comprises that die forefront pressure value changes the back and waits for specified time interval, reads die and station distance values again.
As further improvement of the present invention, said specified time interval is 0.2 second.
As further improvement of the present invention, said S303 step specifically comprises: judge after the die force value changes whether be stabilized in the specified pressure interval, if the spacing that continues to read die and station is first spacing; If not, the control die stops to move and reporting an error.
As further improvement of the present invention, said S304 step specifically comprises: judge whether the riveted joint number of times is preset value, if the control die stops to move to finish riveted joint; If not, the control die moves to next riveted joint position to prepare riveted joint next time.
As further improvement of the present invention, said S304 step also comprises: judge whether die moves to next riveted joint position, if start the riveted joint process; If not, report an error to point out manual work to check.
As further improvement of the present invention, said clinching method also comprises the S305 step: judge whether die is in the special time interval from the time that first spacing moves to second spacing, if control said riveting machine and take out riveting parts from station; If not, report an error to point out manual work to check the riveted joint result.
As further improvement of the present invention, said S305 step also comprises: after reporting an error, authority is restarted in the shutoff system and the system that is provided with, said system restart that authority comprises that specific cryptosystem is restarted and/or specially key restart.
As further improvement of the present invention, said clinching method comprises the S306 step: the control die resets to prepare riveted joint next time.
Compared with prior art; Clinching method provided by the present invention is through accurate control riveted joint process, accurately controls the progress of riveted joint through the displacement transducer that connects die, and monitoring simultaneously connects the pressure sensor of die can judge suitable unlatching riveting process; Again through the whole riveting process time of monitoring as the whether qualified reference of riveted joint; From a plurality of angle control riveted joint processes, whole process is handled in automation simultaneously, has reduced workman's workload; Effectively promoted operating efficiency, simultaneous adaptation large-scale production.

The specific embodiment
Below will combine each embodiment shown in the drawings to describe the present invention.But these embodiment do not limit the present invention, and those of ordinary skill in the art all is included in protection scope of the present invention according to the conversion on structure, method or the function that these embodiment made.
Join shown in Figure 1ly, riveting machine provided by the present invention is carried out riveting work and is specifically comprised the steps:
S10: open riveting machine;
S20: demarcate to riveting machine, judge whether to demarcate and accomplish, if, execution in step S30; If not, execution in step S20 again;
S30: the control snap head of riveting machine is riveted to the riveting parts that is arranged at station, and judges whether the riveted joint completion, if, execution in step S40; If not, execution in step S30 again;
S40: the control manipulator takes off the riveting parts of riveted, and prepares riveted joint next time.
Wherein, the described calibration process of step S20 is to be a very important ring in the riveted joint process, be each workman open behind the riveting machine a step must doing, if do not carry out calibration process, then can't realize effective control for calibration process.
Concrete calibration process comprises the steps:
S201: riveting machine is provided, and riveting machine comprises die and station, and die is connected with displacement transducer to detect the displacement of die with respect to station;
