Referring to fig. 1, an embodiment of the present application provides a method for discriminating a nut for a necking machine, including the following steps:
collecting the closing-in pressure of the nut in real time, and drawing a closing-in pressure real-time graph;
comparing the closing-in pressure real-time curve graph with a preset pressure curve graph;
when the closing-in pressure real-time curve graph is identical to the preset pressure curve graph or fluctuates up and down within an allowable error range, the nut is judged to be good, and the nut is collected, and when the closing-in pressure real-time curve graph is not identical to the preset pressure curve graph or fluctuates up and down within the allowable error range, the nut is judged to be bad, and the nut with the bad is removed.
Wherein, preferably, the closing pressure of the nut is collected in real time by adopting a pressure sensor.
Preferably, when the nut is judged to be a non-good product, the non-good product nut is manually removed; or when the nut is judged to be the defective product, the defective product nut is automatically removed by adopting a discharging mechanism.
According to the above description, in the nut necking machine, a pressure sensor is arranged at the pressure head of the nut necking machine in the process of necking the nut, the necking pressure is monitored in real time, a pressure change trend chart is drawn by the necking pressure collected by the pressure sensor, and as the workpiece in the same batch is required to basically keep consistent with the necking deformation parameters, the drawn pressure change curve is relatively fixed or fluctuates within the allowable error range.
If the pattern changes are different and the difference is larger than a preset range value, judging that the processing technology does not reach the standard, and considering the processing technology as the internal defect of the nut, meanwhile, when nuts with the same appearance of different materials are mixed into the nuts in batches for processing, the pressure curves are inconsistent, and when the system recognizes that the change of the pressure curves to the receiving port is relatively large, an operator can send a prompt about whether the workpieces are mixed or not, or the workpieces are judged to be mixed according to specific conditions, and then a discharging mechanism or a manual discharging mechanism is used for removing the defective nuts or mixed nuts.
Therefore, the method can effectively remove defective nuts and nuts mixed with different materials in the batch, the judging system works automatically, the manpower is liberated, the productivity is improved, in addition, the workpiece is detected immediately after the workpiece is processed, the timeliness is high, the error correction is timely, and the rejection rate is low.
