Description
Technical Field
The invention relates to the technical field of forging production identification, in particular to a method for producing a virtual identification of a forging suitable for a thermal deformation process.
Background
In the current production process, the technical information of processing and assembling of various parts is required to be stored for tracing and inquiring whether the production line is a processing production line or an assembly line. It is a common practice to bind a label (number) to a component, and then store technical information of the processing and assembly of the component in a record indexed by the label and store the technical information in a database. When tracing and inquiring, various related information can be found as long as the label is searched.
Under the normal condition, the binding label for the part can be realized by sticking a bar code, printing a two-dimensional code, recording a serial number and the like on the part, and can also be made into a temporary label, and the temporary label is placed on a follow-up tool of the part (such as a pallet code block of an assembly line), and the label is finished on the part after the work is finished. In summary, two points are necessary: 1. this tag is unique. If not unique, different results may occur in the trace back and query; 2. must coexist with the component parts. If the tag and component are not co-located, then when information needs to be retrieved and recorded, the associated record may not be found.
However, the above method is difficult to be implemented in a thermal deformation process forging line, which is characterized in that workpieces are directly conveyed, and because the workpieces generally have heating, forging or spinning processes, forgings are greatly deformed in a high-temperature environment in the production process, so that even if labels like two-dimensional codes and numbers can be printed or recorded on the workpieces, the labels cannot be marked due to too high temperature, or the labels are damaged along with the processes of heating (generation of oxide scale), forging or spinning (change of surface and shape).
In addition, as the processing procedure is carried out step by step on a production line, unqualified products or products which do not meet the processing conditions appear. When the unqualified products or the products which do not accord with the processing conditions appear, the production line can remove the unqualified products or the products which do not accord with the processing conditions, so the original arrangement sequence is also disturbed.
Therefore, how to define a label for each workpiece in such a production line simply, reliably and efficiently, and accurately record the processing information in a one-to-one correspondence manner, so that the analysis and tracing of the processing quality by a factory becomes a problem to be solved.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The production line shown in fig. 1 is taken as an example for explanation, the production line has 8 stations, and the stations are respectively heating, forging and preforming, forging and pressing forming, trimming, heat treatment, shot blasting, flaw detection and offline warehousing; because the work piece is hot and heavy, all work pieces are transported between the station and are all realized adopting the robot transport.
For convenience of description, the names of heating, forging and preforming, forging and pressing forming, trimming, heat treatment, shot blasting, flaw detection, offline warehousing and the like are not mentioned in the following description, but are simply described by the work piece entering and the work stations 1, 2 and 3 … 8.
In the production line, each station needs to collect data including a plurality of data, such as 4 data of workpiece entering, 1 station and 2 data, and the like, and the total number is 36 real-time process data.
1. The workpiece entered 4 data:
the number of the data entered by the workpiece can be adjusted according to different items, and can be 4 or more, referring to fig. 2, when the workpiece enters a station, a maximum of 4 data can be stored in the station, and the four data can be changed at will according to different station requirements, as shown in fig. 2: data 1-area time/line number, i.e. transit time from the previous station to the present station; data 2-VER 1; data 3-VER 3; data 4-VER 4; each group of data consists of data address offset, namely a storage address and VER, namely storage data, if the storage data exists in the work station, the storage address and the storage data are filled, and if the data does not exist, the storage address and the storage data are filled with 0.
2.36 real-time process data
This data quantity can be adjusted according to different projects, such as the project shown in fig. 4 stores 20 real-time data and 3 temporary data, and the quantity of the real-time data is related to the quantity of data stored per station.
The production line is provided with a plc programmable controller control system (also can be a pc industrial personal computer).
Three storage areas are configured in the control system, namely an index storage area, an index number storage area and a data storage area. The structural form is as follows:
index storage area
Storage area for index number (initialized as follows)
The lower number corresponds to the index number storage location number, which is initially an increasing number sequence starting with 1 as shown above.
In the data area, each set includes 36 data as above, as shown in fig. 4.
The production line is a forging production line, each device in the production line is connected with the master control system PLC through a bus, data can be interconnected and communicated, forging production is a continuous hot working deformation process, an action signal of each device can be transmitted to the master control system PLC through the bus and serves as a trigger signal of each processing station, and if data needs to be stored, data storage is carried out through the trigger signal. The whole production process is monitored and workpiece tracking is carried out through a master control system PLC according to action signals (such as robot grabbing signals, discharging signals and press striking signals) of each device, workpiece indexes can change along with the positions of workpieces from each station to the beginning of feeding, and accurate workpiece data are formed during linkage of the stations and offline of the workpieces.
The following describes the method for generating the virtual tag and the virtual database in the production line by matching with the three areas:
when a local workpiece enters, the robot R1 grabs the workpiece, if the workpiece is an unqualified workpiece, the robot R1 directly puts the workpiece into a waste bin, namely no workpiece enters, and if the workpiece is a qualified workpiece, the workpiece is put into a station 1 for processing; at the moment, the index number of the first position of the index number storage area is provided and sent to the position of the station 1 of the index storage area, meanwhile, the index numbers stored in the index number storage area are sequentially supplemented forwards, and the entered workpiece data is stored in the corresponding data area. As follows:
index storage area
Index number storage area
At this point, the real-time data entered into the workpiece is stored in the first set of locations in the data area. The calculation method for calculating the first address of the data group stored in the data area comprises the following steps: (index-1) X Each set of data lengths (all data for one workpiece during machining) in this example: (1-1) X36 ═ 0.
Since there can only be one workpiece at a station, no new workpiece can enter unless this workpiece is finished and transferred to the next station. When this workpiece is processed, if the processing is acceptable and the station 2 has no workpiece, the robot R2 transfers the workpiece to the station 2. If a workpiece exists in the station 2, the robot R2 waits for the workpiece in the station 2 to be taken away, and then transfers the workpiece to the station 2. At this time, as the workpiece moves, the workpiece index number in the index storage area also moves from the position of the station 1 to the station 2. And after the index number is moved, resetting the position of the original station 1 to wait for the next workpiece to enter. As shown in the following figures:
index storage area
Real-time data of the workpiece at station 1 is stored in a first set of locations in the data area. The first address calculation method is as described above.
If the workpiece is not qualified after being processed at the station 1, the robot R1 directly transfers the workpiece to a waste bin, and simultaneously moves the index number stored in the index number storage area backwards to one position,
index number storage area
The artifact index is then removed from the index store and placed back in the first location of the index store.
Index number storage area
Meanwhile, the data area (first group) corresponding to the serial number (1) corresponding to the original station 1 is reset, so that disorder caused by the entry of subsequent data is prevented.
Since the workpiece in station 1 is removed, a workpiece can enter, and the index storage area are changed as shown in the following figure
Index storage area
Index number storage area
When the workpiece is completely processed after being transported to the station 8, the workpiece is off-line, at the moment, the index number of the index storage area moves backwards by one position, and the index number of the station 8 is placed back to the 1 st position of the index storage area from the index storage area so as to be proposed when the workpiece enters.
In the production line as described above, when no defective product appears during the processing, the form of the index storage area is as follows: the first index number 1 corresponds to station 8 and the eighth index number corresponds to station 1;
index storage area
Storage area for index number (initialized as follows)
If unqualified qualified products appear in the processing process, for example, when a second workpiece (index number 2) is unqualified in the station 3, the index number 2 can be seen to run behind the index number 3, and the index number corresponding to the original station 3 is cleared; the form of the index storage area is as follows:
index storage area
It can be seen that the invention can effectively bind the workpiece and the virtual tag by the method of generating the virtual tag (identification) and the virtual database, thereby solving the problem of storing the process data by checking the number.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
