Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The application provides a method for replacing a stamping die, and referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of the method for replacing the stamping die.
While the present embodiments provide an example of a press die change method, it should be noted that while a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than that shown or described herein. For convenience of description, the following omits the execution of the steps of the main body description press die exchanging method including:
step S110: receiving an abnormal fluctuating sound wave signal generated by a stamping die and collected by an ultrasonic signal detection device arranged on the stamping equipment;
stamping production equipment can utilize the stamping force that self produced to press to the work piece of treating to laminate with the mould for the work piece produces corresponding deformation, thereby reaches stamping production's effect, but in stamping production process, stamping die can lead to producing mould damage, unusual scheduling problem because of use number of times or equipment trouble scheduling problem.
Need monitor stamping die in the punching press production process, avoid the phenomenon of using this mould continuously when the mould damages or appears unusually.
For example, corresponding sound wave signals generated during normal processing such as punching sound waves and workpiece deformation sound waves are generated in the normal punching production process, but when a die is damaged by punching or is abnormal, huge abnormal fluctuation sound wave signals are generated.
Therefore, the punching die is monitored by the acoustic wave detection device, for example, an ultrasonic signal detection device is used, the ultrasonic signal detection device is used for outputting an ultrasonic signal to the die to collect a reflected acoustic signal generated by the die, or the acoustic signal generated by the die is directly monitored and collected when the punching device is produced, so that whether an abnormal problem exists during punching production is monitored.
Step S120: determining the sound source position of the sound wave signal to obtain the position of an abnormal point in a production area where the stamping equipment is located;
the production area of stamping production usually has a plurality of stamping devices, a sound wave signal detection device for monitoring a sound wave signal of the stamping device is arranged on a die of each stamping device, and when the sound wave signal with abnormal fluctuation is received, the sound wave signal is judged to be sent from the sound wave signal detection device at which stamping device in the production area.
The sound wave signals generated in normal production in normal stamping production can cause related workers to ignore the sound wave signals which are abnormally fluctuated, and the positions with problems in the production area cannot be accurately positioned by relying on manpower.
For example, the production area where the punching equipment is located includes a plurality of punching equipment, and the acoustic signal detection device on the punching equipment outputs the acquired signals to the system, and one or more punching equipment currently started and used for production are provided according to the production plan.
When only one stamping device is used, the source position of the sound wave signal does not need to be judged, and after the sound wave signal with abnormal fluctuation is detected, the current stamping device is determined to be at the abnormal point position.
When a plurality of stamping devices are used, the system is required to identify the source positions of the sound wave signals, and the sound wave signals are determined to be collected by the sound wave signal detection device on which stamping device, so that the specific positions of the stamping devices with the abnormal conditions, namely the positions of the abnormal points, are determined.
Illustratively, the determining the sound source position of the sound wave signal to obtain the position of the abnormal point in the production area includes:
step a: determining a punching device generating abnormal fluctuation in a production area based on the sound source position of the sound wave signal;
when receiving an acoustic wave signal which is acquired by an ultrasonic signal detection device arranged on the stamping equipment and generated by an abnormal fluctuation of a stamping die, the source position of the acoustic wave needs to be analyzed, so that the subsequent processing is carried out on the stamping equipment generating an abnormal condition.
The abnormal fluctuation generated by the stamping equipment comprises the problems of die cracking, die corner collapse, stamping workpiece cracking and the like in the stamping production process, namely the abnormal fluctuation generated by stamping comprises two aspects, namely, the corresponding abnormal problem is generated on the die, so that normal production cannot be continued, and the workpiece or the residual material of the workpiece falls into the die, so that abnormal noise is generated in the production process, for example, the workpiece is cracked, the residual material is deformed, so that the residual material is flicked and impacted on the die.
Step b: outputting a stop instruction to the stamping equipment generating the abnormal fluctuation, wherein the stop instruction is used for stopping the production process of the stamping equipment generating the abnormal fluctuation;
when receiving an acoustic wave signal which is generated by an abnormal fluctuation of a stamping die and collected by an ultrasonic signal detection device arranged on the stamping equipment, determining the stamping equipment generating the acoustic wave signal in a production area according to the sound source position of the acoustic wave signal, and stopping the working state of the stamping equipment, namely stopping production, so as to avoid the phenomenon that the die is damaged and the defective goods are produced and processed by keeping production.
The stop instruction is a control instruction, is output to the punching equipment which generates abnormal fluctuation by the system, and stops the current processing process after the punching equipment receives the stop instruction.
For example, when receiving an acoustic wave signal of abnormal fluctuation generated by a stamping die, which is acquired by an ultrasonic signal detection device arranged on the stamping device, the stamping device using the stamping die stops operating, and the purpose includes two aspects, namely, the abnormal fluctuation may be generated when the die is damaged, the stamping device stops operating continuously, production defective goods caused by continuous processing due to the damage of the die are avoided, and the abnormal fluctuation may be abnormal noise generated by a workpiece or workpiece defective materials, the stamping device stops at the moment, and the workpiece or workpiece defective materials are prevented from generating adverse effects on the die in subsequent production.
When the sound wave signal that the stamping die produces the unusual fluctuation is received promptly, directly stop stamping equipment's operation, firstly avoid the mould to produce the damage, secondly avoid producing the wastrel.
Step c: and marking the position of the abnormal point of the punching equipment which stops production.
At this moment, the stamping equipment that stamping die produced unusual undulant stops operating, and this stamping equipment current state is the shutdown state promptly, for guaranteeing production efficiency, needs adjust this stamping equipment, needs to detect this stamping equipment's stamping die promptly, confirms whether stamping die exists to the incomplete material of work piece and the work piece of producing clears up, avoids it to cause the damage scheduling problem to stamping die.
For example, before the controlling the die changing device provided on the punching apparatus to replace the die to be used in the waiting area to the position of the abnormal point, the method includes:
step d: after stamping equipment for marking production stop is an abnormal point position, carrying out shock wave detection on a stamping die at the abnormal point position to obtain a detection result;
when the sound wave signal of the abnormal fluctuation is received, but it cannot be determined which type of abnormal problem the sound wave signal represents, it is necessary to determine the type of the abnormal fluctuation at the position of the abnormal point.
After the abnormal point position is marked, the abnormal fluctuation type of the abnormal point position needs to be judged, and the punching die at the abnormal point position is subjected to shock wave detection, so that whether the punching die has problems or not is judged, and the abnormal fluctuation type is further determined.
The detection result is the quality detection of the stamping die, the stamping die outputs stamping waves, the stamping die can generate impact echoes according to the self state, and the detection result is the detection of the impact echoes generated by the stamping die.
The abnormal fluctuation generated at the position of the stamping die is two types, one type is the problem that the die is damaged, and the other type is the abnormal sound generated by the stamping die caused by the workpiece or the workpiece scraps, so that different types of abnormal problems can be solved, and different coping results can be generated.
Wherein, when the unusual fluctuation that stamping die produced damages for mould self, then need replace this stamping die to guarantee that stamping equipment can continue normal production.
Wherein, when the unusual fluctuation that stamping die produced leads to stamping die to produce unusual sound for work piece or work piece defective material, it does not have quality problems such as fracture, collapse angle to confirm stamping die this moment, promptly stamping equipment uses current stamping die can continue production, but the influence factor to stamping die is uncertain this moment, probably lead to stamping die to produce the sound for work piece or work piece defective material, also probably be the problem that stamping equipment self produced, then the system can output prompt message to relevant staff department this moment for the relevant staff inspects stamping equipment, whether check stamping equipment is normal, whether have work piece defective material scheduling problem.
Step e: and if the detection result does not meet the preset standard, marking the stamping die as a die to be replaced.
And if the detection process of the stamping die is shock wave detection, the detection result is the shock echo data of the stamping die, and whether the detection result meets the standard or not is judged, namely whether the shock echo data of the detection result is close to the standard value or not is judged.
The preset standard is the standard of the impact echo data when the quality of the stamping die is qualified and the problems of cracking, corner breakage, hole breakage and the like do not occur.
Illustratively, two results exist in the judgment process, the detection result meets the preset standard, and the detection result does not meet the preset standard, and different actions are executed according to different judgment results.
When the detection result meets the preset standard, the quality of the detected stamping die is proved to have no problem, namely the stamping die can be continuously used.
And when the detection result does not meet the preset standard, the quality of the detected stamping die is proved to have a problem, and the detected stamping die is marked as a die to be replaced.
The to-be-replaced die is the stamping die with quality problems currently used by the stamping equipment, and the stamping equipment can recover production only after the stamping die with quality problems is replaced.
For example, the performing the shock wave detection on the stamping die at the position of the abnormal point to obtain a detection result includes:
step f: outputting an action command to a metal impact hammer, wherein the action command is used for calling the metal impact hammer to impact a stamping die at the abnormal point position;
when impact detection is carried out on the stamping die, the metal impact hammer needs to be called through a system, and the metal impact hammer is used for impacting the stamping die, so that impact echo is generated in the content of the stamping die, and then impact wave detection is carried out on the stamping die.
Illustratively, when the metal impact hammer impacts the stamping die, a corresponding shock wave is generated, the metal material of the metal impact hammer comprises but is not limited to common materials such as iron and copper, and meanwhile, the metal impact hammer can also be replaced by other equipment for generating the shock wave to the stamping die.
Step g: receiving impact echo data generated by the stamping die;
when strikeing stamping die, stamping die is the metal material together, and the inside impact echo that can produce of stamping die to when carrying out the shock wave detection to stamping die, can receive the impact echo from stamping die department.
For example, the shock echo data may include a plurality of possibilities, for example, a crack may exist in a stamping die or a hollow structure may exist in the middle of the stamping die, when the shock wave reaches such a structure, the shock wave may generate a shock echo, that is, a time length for returning the shock echo is used to determine whether a hollow result or a crack exists in the structure of the current die, and the like.
Step h: and detecting the sound wave peak value change condition of the impact echo data to obtain a detection result.
The impact echo data includes the change condition of the impact echo, and a corresponding impact echo is generated at a position where the impact wave meets the structural change of the stamping die, namely the impact echo data is detected to mainly detect the peak value size of the sound wave peak value of the impact echo data, the change time of the sound wave peak value and the like.
Illustratively, if the detection result does not meet the preset standard, marking the stamping die as a die to be replaced includes:
step i: and if the sound wave peak value change in the detection result is different from the preset sound wave change, determining that the detection result does not meet the preset standard, and marking the stamping die as a die to be replaced.
And when the detection result is judged to meet the preset standard, judging whether the sound wave peak value change in the detection result is different from the preset sound wave change.
The preset sound wave variation is a peak variation of the shock wave data in a preset standard.
When the stamping die is not damaged, impact wave detection is carried out on the stamping die, the obtained detection result is a preset standard, the sound wave peak value change condition of an impact echo in the preset standard is preset sound wave change, when the stamping die has a damage problem, such as die cracking, the impact echo data of the stamping die can be changed, wherein the sound wave peak value change of the impact echo can be changed along with the change according to different cracking positions of the stamping die, namely the time change of the highest sound wave peak value of the impact echo occurs.
Illustratively, cracking occurs at an intermediate position on the press die where the shock wave immediately produces a shock echo when the shock wave reaches the cracking position, i.e., the time for detecting the shock echo when the die cracks is shorter than the time for detecting the shock echo when the die is intact.
The method comprises the steps of comparing the sound wave peak value change condition in a detection result with the preset sound wave change condition, wherein if the two sound waves are similar, the stamping die is not damaged, and if the two sound waves are different, the stamping die is damaged.
When determining that there is the problem of damage in stamping die, mark this stamping die for treating the replacement mould, treat that the replacement mould just can guarantee stamping equipment to maintain the stamping die of normal production operation promptly for needing to be replaced.
Step S130: controlling a die replacing device arranged on the stamping equipment to replace a die to be used in a waiting area to the position of the abnormal point so as to maintain normal production of the production area; the waiting area is an area corresponding to the abnormal point position and used for storing the die to be used.
And outputting a control instruction, controlling a die replacing device on the stamping equipment to remove the die at the abnormal point position, and installing the die in the waiting area to the abnormal point position, so as to finish the effect of replacing the die.
The mould replacing device can transfer the mould to be automatically put on the shelf and locked and fixed.
The waiting area corresponds to the production area, and the dies to be used stored in the waiting area are all in mapping relation with each stamping device in the production area, namely, each stamping device is divided into one waiting area for storing the dies to be used.
The die to be used is a die to be used and is used for replacing a damaged die on the stamping equipment or replacing production contents.
For example, after the controlling the die changing device provided on the punching apparatus to replace the die to be used in the waiting area to the abnormal point position, the method includes:
step j: outputting a conveying instruction to a transport vehicle, wherein the conveying instruction is used for calling the transport vehicle to convey the replaced stamping die to a die warehouse;
the replaced stamping die is a stamping die with a damage problem, and a transport Vehicle is required to be called to transport the stamping die to a die library, wherein the transport Vehicle usually adopts an Automated Guided Vehicle, which is called an AGV for short, and is also called an AGV trolley. The present invention relates to a transport vehicle equipped with an electromagnetic or optical automatic navigation device, capable of traveling along a predetermined navigation route, and having safety protection and various transfer functions. The industrial application does not need a driver's transport vehicle, and a rechargeable storage battery is used as a power source of the industrial application. Generally, the traveling path and behavior can be controlled by a computer, or the traveling path can be established by using an electromagnetic rail, which is adhered to the floor, and the automated guided vehicle moves and operates according to the information brought by the electromagnetic rail.
Meanwhile, the AGV trolley is provided with a recognition device for recognizing the stamping die, the stamping die is usually provided with marks for recording the specific use information of the stamping die, such as an identification information card or an identification two-dimensional code, and the like, the recognition device on the AGV trolley can recognize the identification information card or the identification two-dimensional code and the like on the stamping die, and the stamping die is conveyed to an appointed die library according to the recognized information.
Step k: and after the transport vehicle finishes the conveying action, outputting a marking instruction to a management system of the mold warehouse, wherein the marking instruction is used for marking the replaced mold as a mold to be maintained.
When the transport vehicle transports the stamping die to the die warehouse, a marking instruction is output to the management system, and the marking instruction can mark the replaced die as a die to be maintained.
Meanwhile, the management system of the mold warehouse can recognize the mold to be maintained, change instructions are carried out on the mold to be maintained, reservation maintenance items are carried out according to the specific conditions of the mold to be maintained, and reservation contents are output to related workers to prompt the related workers to maintain the mold to be maintained in time.
Compared with the prior art, when the stamping die is damaged or has other abnormalities, the stamping die with the abnormality needs to be replaced by searching for a replacement die in a die library, and the searched replacement die also has the problem that the replacement die cannot be used, so that the efficiency of the replacement die is low, and the production efficiency is low, in the application, whether the stamping production is abnormal or not is judged by detecting a sound wave signal generated in the stamping production process, when the sound wave signal with abnormal fluctuation is received, the position of the abnormal point in the current production area is determined, the die to be used in a waiting area corresponding to the position of the abnormal point is judged, the die to be used is directly called and replaced to the position of the abnormal point, the die capable of being used for recovering the production is saved from the die library, and the die with the position of the abnormality is directly replaced after the abnormality is generated in the production area, therefore, the waiting time for recovering production is shortened by improving the efficiency of replacing the mold, the production efficiency is improved, namely when abnormal fluctuation sound wave signals are detected, namely when the production area is abnormal, the mold to be used in the waiting area is directly replaced to the abnormal point position of the production area, the efficiency of replacing the mold is improved, the waiting time for recovering production is shortened, and the production efficiency is improved.
Exemplarily, referring to fig. 2, fig. 2 is a schematic flow chart of a second embodiment of the stamping die replacing method of the present application, and the second embodiment is proposed based on the above first embodiment of the stamping die replacing method of the present application, and the method further includes:
step S210: determining a first waiting area and a second waiting area corresponding to the abnormal point position based on a preset mapping relation and the abnormal point position;
the abnormal point position is stamping equipment which generates abnormal problems in the production area, each stamping equipment corresponds to one waiting area, each waiting area corresponding to the stamping equipment is divided into two waiting areas, namely a first waiting area and a second waiting area, and different types of stamping dies are stored in the first waiting area and the second waiting area.
The preset mapping relation is the relation between the initially divided waiting area and the production area, the production area is divided into working areas of a plurality of stamping devices, the corresponding working areas in the waiting areas are divided into combination areas of the first waiting areas and the second waiting areas, and the first waiting areas and the second waiting areas in each combination area correspond to the production area.
Step S220: if the first waiting area has a die to be replaced, controlling a die replacing device arranged on the stamping equipment to take and replace the die to be replaced to the abnormal point position, wherein the die to be replaced is used for maintaining the current production content of the stamping equipment;
the process of replacing the stamping die on the stamping device by the die replacement device on the control device and the stamping device is the same as that in the first embodiment, and is not described herein again.
When the die to be used is called, the type of the die to be used in the waiting area needs to be judged, wherein the first waiting area is stored with the same stamping die currently used by the stamping device, namely the die to be replaced, and the second waiting area is stored with a different stamping die currently used by the stamping device, namely the die to be updated.
For example, the dies to be used are stored in the waiting area, wherein the dies to be replaced are stored in the first waiting area, and the dies to be updated are stored in the second waiting area, but there is a case where the stamping die currently used by the stamping apparatus has no replacement die, that is, there is no stamping die in the first waiting area.
When the die to be used is taken out, the die to be used is conveyed to the stamping equipment by using the slide rail arranged between the production area and the waiting area, the replaced stamping die is conveyed to the waiting area by the slide rail, the replaced stamping die is placed in the waiting area, and the waiting transport vehicle is conveyed to the die warehouse.
Therefore, before the to-be-used dies in the waiting area are called, the type of the dies in the waiting area is judged, namely whether the dies to be replaced exist in the first waiting area is judged, and when the stamping dies exist in the first waiting area and the second waiting area, the to-be-replaced dies in the first waiting area are preferentially used so as to maintain the production work order schedule of the current stamping equipment by using the to-be-replaced dies.
Step S230: and if the die to be replaced does not exist in the first waiting area, controlling the die replacing device to call and replace the die to be updated in the second waiting area to the abnormal point position, wherein the updated die is used for updating the production content of the stamping equipment.
And when the fact that the die to be replaced does not exist in the first waiting area is judged, the die to be updated in the second waiting area is directly called and replaced to the stamping equipment, and the die to be updated in the second waiting area is used for updating the production content of the stamping equipment.
The calling and replacing processes are the same as those described above, and are not described herein again.
For example, after the controlling the mold exchanging device to transfer and replace the mold to be updated in the second waiting area to the abnormal point position, the method includes:
