[0045] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] First, some technical terms in this application are explained to facilitate those skilled in the art to understand this application.

[0047] BOM: The bill of materials data of a product is a set of technical documents that describe the structural attributes of a product and from which the manufacturing attributes, production attributes, cost attributes and sales attributes of the product can be derived.

[0048] Standard time: The working time required to complete the work in accordance with quality requirements under normal working conditions, using standard working methods, reasonable labor intensity and speed.

[0049] Benchmark time: refers to the technical unit of time corresponding to each demonstration standard operation based on the number of parts, part shape, number of fixing points, hole length, fixing method, etc., the design and construction style of the relevant assembly, and manual work as the premise, to create a demonstration standard operation.

[0050] Basic process working hours: The time determined during process design and set according to the work sheet is used to evaluate the quality of the production line structure determined by the process design.

[0051] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0052] On the first aspect, the embodiment of the present application provides a method for constructing and applying a standard stamping working time system. By defining the basic process, basic process working time, and benchmark time multiplier of the parts, the basic process working time of the stamping parts at the lower level is summed through the system hierarchical data structure. For newly added stamping parts, it is linked and interconnected with the stamping parts production preparation task notification, and tasks are pushed accurately in real time, and online working time maintenance is performed. After the maintenance is completed, the system performs calculations according to the defined rules of the process flow, thereby obtaining the total stamping working time of a single stamping part, thereby constructing the standardized working time of the stamping parts.

[0053] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the construction and application method of the stamping standard working time system for this application. Figure 1 As shown in the figure, the construction and application methods of the stamping standard working time system include:

[0054] S1: Standardize the basic processes and working hours of stamping parts. The forming process of stamping parts includes blanking, automatic or manual shearing, blank packaging, and stamping, and each forming process corresponds to a basic process.

[0055] S2: Based on the process rhythm and number of staff of the basic process, the basic process working hours of the basic process are calculated. According to the sum of the basic process working hours of all basic processes of the stamping parts and the benchmark time multiplier corresponding to the stamping parts, the total stamping working hours calculation logic of the stamping parts is constructed;

[0056] Specifically, for the current basic process, the process rhythm corresponding to the current basic process and the number of staff are multiplied to obtain the basic process working hours of the current basic process; for the current stamping part, the sum of all basic process working hours of all basic processes of the current stamping part is multiplied by the benchmark time multiplier of the current stamping part to calculate the total stamping working hours of the current stamping part;

[0057] S3: Construct a standard working time system according to the total stamping working time calculation logic, and based on the standard working time system and combined with the basic process of the current stamping part, realize the total stamping working time calculation of the current stamping part.

[0058] As shown in Table 1 below, a single stamping part includes four forming processes during the stamping operation, namely blanking, automatic or manual shearing, blank packaging, and stamping. Each forming process has at least one basic process. Specifically, the basic process of blanking includes overhead crane die changing, package opening, uncoiling line, and inspection; the basic process of automatic or manual shearing includes shearing operation; the basic process of blank packaging includes packaging; the basic process of stamping includes stamping line and overhead crane die changing.

[0059] Table 1

[0060]

[0061] Through the above operations, the standardized definition of basic processes is achieved.

[0062] Furthermore, the standardized definition of the basic process working hours for each basic process is as follows:

[0063] According to the process beat and number of staff for the overhead crane die change in the basic process of blanking, the basic process working hours of the overhead crane die change in the basic process of blanking are calculated;

[0064] According to the process rhythm and number of staff in the basic process of blanking, the basic process working hours of the package opening in the basic process of blanking are calculated;

[0065] According to the process beat and number of staff of the uncoiling line in the basic process of blanking, the basic process working hours of the uncoiling line in the basic process of blanking are calculated;

[0066] According to the process rhythm and number of staff in the basic process of blanking, the basic process working hours of the inspection in the basic process of blanking are calculated;

[0067] The basic process working hours of the shearing operation in the basic process of automatic or manual shearing are calculated based on the process takt time and number of staff for automatic shearing, as well as the process takt time and number of staff for manual shearing;

[0068] According to the process rhythm and number of staff in the basic process of blank packaging, the basic process working hours of the basic process of blank packaging are calculated;

[0069] According to the process rhythm and staffing number of the press line in the basic process of stamping forming, the basic process working hours of the press line in the basic process of stamping forming are calculated;

[0070] According to the process rhythm and number of staff for the overhead crane die change in the basic process of stamping forming, the basic process working hours of the overhead crane die change in the basic process of stamping forming are calculated.

[0071] The following is a detailed explanation of the basic process hours.

[0072] Regarding the basic process labor hours for the overhead crane die change in the basic blanking process, each stamped part is stamped and formed by a different die. Therefore, the corresponding die needs to be replaced before the stamping part is produced. Each die change takes a long time and needs to be evenly distributed to each stamped part. For example, as shown in Table 2 below, the conventional die change time is 25 minutes, each die change requires the cooperation of 2 people, and the average production is 600 pieces. Therefore, the process tact time of the overhead crane die change = 25 / 600 = 0.042 minutes / piece, and the basic process labor hours are process tact time * staffing = 0.042*2 = 0.084 minutes / piece.

[0073] Table 2

[0074]

[0075] For the basic process working hours of unpacking in the basic process of blanking, the initial supply state of the raw materials for stamping parts is coil material, and the coil material packaging needs to be unpacked. For example, as shown in Table 3 below, the coil material unpacking time is 10 minutes, the average production is 550 pieces, and the staff is 1 person. The process rhythm = 10 / 550, and the basic process working hours = 10 / 550*1.

[0076] Table 3

[0077]

[0078]

[0079] Regarding the basic process hours of the unwinding line, a basic process in blanking, after the raw material coils of stamping parts are unpacked, they need to be cut into sheets of different sizes on the unwinding line. The unwinding line cycle time depends on the length of the stamping part blank, or the pitch. The pitch is divided into four categories: small pitch, medium pitch, large pitch, and special pitch. Each pitch type has a different number of pieces per minute. The process cycle time = 1 / SPM (number of cuts per minute). The basic process hours = process cycle time * staffing. See Table 4 below for details.

[0080] Table 4

[0081]

[0082] The basic process time required for blanking inspections involves checking the dimensions and appearance of the cut sheets, which also requires staffing. Inspection is typically performed on the first sheet after cutting. For example, as shown in Table 5 below, if a single unwinding cycle is 250 sheets, the process cycle time = 1 / 250 = 0.02, and the basic process time = 0.02 * 1 = 0.02.

[0083] Table 5

[0084]

[0085] For the basic process working hours of the basic process cutting operation in automatic or manual cutting, after the stamping parts are uncoiled, some stamping parts cannot be cut into place in one time and require automatic or manual secondary cutting. For example, as shown in Table 6 below, the automatic cutting SPM is 2, the process takt is 0.5, and the manpower is 2, then the basic process working hours of automatic cutting = 0.5*2=1; the manual cutting SPM is 4, the process takt is 0.25, then the basic process working hours of manual cutting = 0.25*2=0.5. SPM in this application refers to standard production minutes.

[0086] Table 6

[0087]

[0088] Regarding the basic process working hours for packaging of blanks, the sheets need to be packaged after being cut. For example, as shown in Table 7 below, it takes one person 3 minutes to complete the packaging of a stack of materials. Therefore, the packaging process rhythm = 3 / 250 = 0.012, and the basic process working hours = 0.012*1 = 0.012.

[0089] Table 7

[0090]

[0091] Regarding the basic process hours for the press line, which is a basic process in stamping, the packaged sheets need to go through the stamping process before they can be transformed into stamped parts for welding. The press line forms the sheets through a series of dies into stamped parts. Due to the different specifications and structures of stamped parts, the process takt time and staffing for each stamping part are different. Based on the existing product types and structures, stamping parts are divided into seven types (see Table 8 below). The specific process takt time, staffing, and basic process hours are shown in Table 9 below.

[0094] Table 9

[0095]

[0096]

[0097] Regarding the basic process hours for overhead crane die change in stamping, each stamping part has a corresponding forming die. The die needs to be changed before each stamping part is produced. The die change time is related to its storage location. A die change in the same bay takes 50 minutes, while a die change in a non-span takes 90 minutes. An average of 350 pieces can be produced with one die change. For example, Table 10 below shows this.

[0098] Table 10

[0099]

[0100] Furthermore, the benchmark time multiplier is a parameter used to measure the performance of the production line. Based on the measured total stamping working hours and the benchmark time of the stamping parts, the benchmark time multiplier of the stamping parts is calculated. The basic process working hours in this application are the time under theoretical conditions. There is waste of working time in actual production, such as the lack of work content and insufficient work of personnel, the addition of multiple inspections to the process to ensure quality, and the improvement of personnel product skills. Therefore, according to the characteristics of product molding, the basic series is sorted out, summarized and defined. The benchmark time multiplier of the basic series is obtained by measuring the working hours of the basic series parts and dividing them by the benchmark time of the series parts. As shown in Table 11 below, for the B19 supplementary series, the benchmark time multiplier of the left side outer panel of the stamping part 5401071-G0**** is 1.083. The subsequent stamping parts belonging to the B19 supplementary series all have a benchmark time multiplier of 1.083, thereby realizing the rapid measurement of the working hours of batch stamping parts.

[0101] Table 11

[0102]

[0103] Furthermore, in one embodiment, a standard working time system is constructed according to the total stamping working time calculation logic. Based on the standard working time system and in combination with the basic process of the current stamping part, the total stamping working time calculation of the current stamping part is realized, specifically including:

[0104] S301: Constructing a standard working hour system according to the total stamping working hour calculation logic;

[0105] S302: Based on the constructed standard working time system and combined with the basic process of the current stamping part, the total stamping working time of the current stamping part is calculated;

[0106] S303: BOM data tasks are associated to perform task dispatching. After the trial production of the whole vehicle, when the current stamping part is generated, the total stamping working hours of the current stamping part are obtained by calculation, and the basic process working hours of each basic process of the current stamping part are obtained by splitting.

[0107] Specifically, a standard working time system based on standard processes is constructed. This application designs the standard working time system from two aspects. The first is the construction of the standard working time system to solve the problems of traditional offline calculation mode and accuracy; the second is to associate BOM data for task distribution to solve the lag.

[0108] A basic database is constructed with 4 forming processes and 8 basic working procedures. The staffing, process rhythm and SPM of the basic working procedures are maintained in the basic database in sequence. Then, the basic working procedures to which each stamping part belongs are judged and selected in turn to complete the construction of the total stamping working hours for each part.

[0109] Tasks are assigned by associating BOM data with tasks. Regular maintenance of working hours occurs after vehicle trial production, while ideally, maintenance is performed after the release of the part preparation notice. Once the stamped part is produced, the standard working time system automatically captures the time data for maintenance. To address this lag, it's necessary to first understand the typical business process: R&D design data → Release of document design notice → Release of part preparation notice → Release of part near-completion notice → Release of vehicle and part production notice. Vehicle trial production begins after the release of the part preparation notice, while mass production of the vehicle occurs after any issues with the vehicle trial production have been resolved and part preparation is complete. After vehicle trial production, the process verifies working hours and reports them using a spreadsheet. This time impacts worker wages, and due to the large volume of parts, process verification can lead to lags. The solution is to push tasks after the preparation notice is released. After the part preparation notice is released, the part route attributes from the vehicle data are identified. The standard working time system identifies the manufacturing and assembly routes and pushes attributes such as the part number and name to the primary process in real time. The process then assigns working hours to the basic process based on the basic forming process.

[0110] After the production preparation notice creates a labor task, it generates labor object maintenance parameters, such as maintenance parameters for part secondary shearing, step selection, part attribute selection, and base time multiplier. After the maintenance is completed, the total stamping labor time for the stamping part can be calculated.

[0111] In a second aspect, the embodiments of the present application also provide a stamping standard working time system construction and application device.

Figure 2As shown, the construction and application device of the stamping standard working time system includes: a definition module, a construction module, and an execution module.

[0113] The definition module is used to standardize the basic processes and basic process working hours of stamping parts. The forming process of the stamping parts during stamping includes blanking, automatic or manual shearing, blank packaging, and stamping forming, and each forming process corresponds to a basic process; the construction module is used to calculate the basic process working hours of the basic process based on the process rhythm and number of staff of the basic process, and construct the total stamping working hour calculation logic of the stamping parts according to the sum of the basic process working hours of all basic processes of the stamping parts and the benchmark time multiplier corresponding to the stamping parts; the execution module is used to construct a standard working hour system according to the total stamping working hour calculation logic, and based on the standard working hour system and combined with the basic process of the current stamping parts, realize the calculation of the total stamping working hour of the current stamping parts.
