The control device 3 obtains the stamping tonnage between the upper die 12 and the lower die 13 of the stamping device 1 and the current size values of the upper die 12 and the lower die 13, and can determine whether the upper die 12 reaches the bottom dead center of stamping according to stamping tonnage data. A trimming report is generated according to the sensor position, the stroke data, the stamping tonnage and the current size value and transmitted to the display screen 31, so that the trimming report is displayed through the display screen 31, and a worker can conveniently trim the upper die 12 and the lower die 13 according to the trimming report.
For example, when the current concave size of the concave plate of the lower die 13 is 3mm and the stamping tonnage of the upper die 12 to the lower die 13 reaches 400T, it indicates that the upper die 12 has reached the stamping bottom dead center, the workpiece 5 to be processed is bent, and at the same time, the edge portions of the workpiece 5 to be processed are contacted with the sensors 22 numbered 1-1 and 1-2, and both the sensors 22 are compressed by 0.3mm, that is, the stroke data of the sensors 22 are all 0.3mm, which indicates that the bending height of the workpiece 5 to be processed exceeds the preset threshold.

It will be appreciated that the control device 3 aggregates all the trimming reports and generates aggregate data, which can be invoked by a worker by pressing the control button 33, and that the control device 3 transmits the aggregate data to the display screen 31 for the worker to view the aggregate data and provide instructional comments for the production of the upper and lower molds 12, 13 based on the aggregate data.
In an embodiment of the present invention, please refer to fig. 1, 2 and 5 again, the step of obtaining the sensor position contacting the edge portion of the workpiece to be processed and the stroke data of the sensor further includes: s7411, if all sensors of the monitoring device generate stroke data, generating word prompt information that the setting of the monitoring station is unreasonable.
In this embodiment, the control device 3 obtains the sensor position contacting the edge portion of the workpiece 5 to be processed and the stroke data of the sensors 22, if all the sensors 22 generate stroke data, it indicates that all the sensors 22 contact the edge portion of the workpiece 5 to be processed, which indicates that the setting of the monitoring station is unreasonable, the control device 3 controls the stamping device 1 to stop immediately, generates text prompt information indicating that the setting of the monitoring station is unreasonable, and transmits the text prompt information to the display screen 31 for the staff to check. Meanwhile, the control device 3 can also control the loudspeaker 32 to give out a buzzing prompt tone and control the warning lamp 4 to light up so as to prompt the staff to process in time and avoid damaging the sensor 22.

In this embodiment, after all the sensors 22 contact the edge portion of the workpiece 5 to be processed, in order to avoid the sensors 22 from being pressed and not returning to the preset position, the control device 3 detects the deviation values between all the sensors 22 of the monitoring device 2 and the preset position. If the deviation value is zero, it indicates that the sensor 22 has recovered to the preset position; if the deviation value is not zero, it means that the sensors 22 are not restored to the preset position, the stamping device 1 is controlled to stop the stamping operation, the display lamp 4 is controlled to be turned on, the speaker 32 is controlled to emit a prompt tone, the adjustment parameters are set according to the deviation value, and the adjustment parameters are transmitted to the display screen 31, so that the staff can adjust the positions of the sensors 22 according to the adjustment parameters, and all the sensors 22 of the stamping device 1 are at the preset positions before stamping, thereby avoiding the monitoring deviation of the sensors 22.
In an embodiment of the present invention, please refer to fig. 1, 2 and 6 again, the monitoring device 2 further includes an in-place sensor, and the step of acquiring the bending height data of the edge portion of the workpiece to be processed, which is monitored by the monitoring device, further includes: s61, judging whether a workpiece to be processed completely covers a processing station by an in-place sensor, and transmitting in-place information to a control device; s62, if yes, continuing the stamping operation by the stamping device; and S63, if not, stopping the punching device.
In this embodiment, the monitoring device 2 further includes an in-place sensor, which is disposed on the stamping device 1, and can determine whether the workpiece 5 to be processed is completely covered on the processing station 11, and if the workpiece 5 to be processed is not completely covered on the processing station 11, the stamping device 1 may cause damage to the stamping device 1 and the sensor 22 when the stamping device 1 performs stamping operation.
It can be understood that the in-place sensor judges whether the workpiece 5 to be processed completely covers the processing station 11, if the workpiece 5 to be processed completely covers the processing station 11, an electric signal for continuing operation is generated and transmitted to the control device 3, and the control device 3 controls the punching device 1 to continue punching operation according to the received electric signal. If the workpiece 5 to be processed does not completely cover the processing station 11, an electric signal for generating a pause operation is transmitted to the control device 3, the control device 3 controls the stamping device 1 to pause the stamping operation according to the received electric signal, controls the warning lamp 4 to be lightened, and simultaneously controls the loudspeaker 32 to give out a prompt tone so as to prompt a worker to check the processing station 11, and the workpiece 5 to be processed is placed into the processing station 11 in a supplementing manner in time, so that the stamping device 1 or the inductor 22 is prevented from being damaged due to the air compression of the stamping device 1, and the service lives of the stamping device 1 and the inductor 22 are prolonged.
In an embodiment of the present invention, referring to fig. 6 again, if the bending height data is within a preset threshold, the step of controlling the stamping device to continue the stamping operation further includes: s731, recording the stamping times of the stamping device until the acquired bending height data are out of a preset threshold value; s732, fitting to obtain a stamping limit value of the stamping device.
In this embodiment, the control device 3 compares the received bending height data with a preset threshold, if the bending height data is within the preset threshold, which indicates that the workpiece 5 to be processed, which is punched and bent by the punching device 1, meets the corresponding production standard, then the punching device 1 is controlled to perform punching operation, and the number of punching times of the punching device 1 is recorded, until the obtained bending height data is outside the preset threshold, and the recorded number of punching times of the punching device 1 is fitted to obtain the punching limit value of the punching device 1. Since the stamping device 1 is worn to some extent during each stamping bending operation, the dimension of the workpiece 5 obtained by the stamping device 1 after a plurality of stamping may deviate. Therefore, by recording the number of stamping times of the stamping device 1, the stamping limit value of the stamping device 1 is fitted, so that the working personnel can know the service life of the stamping device 1 of the same type conveniently.
In an embodiment of the present invention, referring again to fig. 6, the step of fitting to obtain the press limit value of the press device further includes: s733, transmitting the stamping limit value to a display screen, and performing reciprocal and flickering early warning along with stamping operation of the stamping device.
