Description

Technical Field

[0001] The invention belongs to the field of aviation manufacturing technology management and relates to a forging and casting blank design method based on maturity parallel design. Background Art

[0002] In the process of aviation manufacturing technology management, when forgings and castings are required for the detailed design of model development, forging and casting blank design needs to be carried out to ensure the normal manufacturing, acceptance and satisfaction of forging and castings and to meet the requirements of parts processing technology; at the same time, when the part design changes, the forging and casting blank needs to be adaptively changed in time. At present, in the process of forging and casting blank design implementation in aviation main engine factories, the forging and casting blank drawing design work is generally started after the part drawings are officially released, and the forging and casting blank drawings are edited and signed offline, which has many problems such as long forging and casting blank design cycle, lack of process control, large signing workload, difficulty in archiving query, and statistical analysis. Summary of the invention

[0003] The present invention provides a forging blank design method based on maturity parallel design, and a forging blank design process based on maturity parallel design, aiming to use system structured management to solve the problems of long offline forging blank design cycle, lack of process control, large signing workload, difficulty in archiving query, and statistical analysis.

[0004] In order to achieve the above tasks, the present invention adopts the following technical solutions:

[0005] A forging and casting blank design method based on maturity parallel design, comprising:

[0006] Step 1: Identify the design requirements of forging and casting blanks

[0007] Obtain part data from the 3D design platform, and use maturity and material grade as screening conditions to select part data that meets the preset requirements;

[0008] Establish a forging and casting database for storing forging and casting record information and blank numbers, wherein the blank number and the forging and casting record information are in a one-to-one or one-to-many relationship; the blank number is the code assigned to the blank of the part to be made;

[0009] Generate forging and casting record information based on part data, store the forging and casting record information in the forging and casting database, and compare it with the forging and casting record information already in the database:

[0010] When the part number in the forging and casting record information is different from the part number of a forging and casting record information already in the database, the forging and casting record information is added to the database and assigned a blank number, specifically: the forging and casting record information already in the database is retrieved, and it is determined whether the material brand and heat treatment state of the forging and casting record information are the same as the existing forging and casting record information. If they are the same, it is determined whether the difference between the corresponding part digital models is within a preset range. If they are within the preset range, the blank number corresponding to the existing forging and casting record information is assigned to the new forging and casting record information, otherwise a new blank number is assigned to the forging and casting record information;

[0011] Step 2: Distribute rough drawing design tasks

[0012] For the forging and casting record information of the newly generated blank number, establish the development task of the forging and casting blank, set the designer and completion time, and push the development task to the designer;

[0013] Step 3: Carry out rough drawing pre-design

[0014] The designer receives the task of developing forging and casting blanks and carries out forging and casting blank design based on the part digital model, process standards and technical standards;

[0015] After completing the blank design offline, upload the preliminary designed blank drawing;

[0016] After the maturity of the part information corresponding to the forging and casting in the three-dimensional design platform reaches the second preset maturity, the blank drawing will be published.

[0017] Furthermore, the three-dimensional design platform includes a VPDM platform.

[0018] Furthermore, the screening conditions are that the maturity is not less than a first preset maturity and the material grade is forgings.

[0019] Furthermore, each forging and casting record information includes a part number, material brand, heat treatment status, single machine quantity, machine model, and part digital model.

[0020] Furthermore, the maturity refers to the degree of completion of a part at different stages of the design process on the three-dimensional design platform.

[0021] Furthermore, the second initially set maturity is higher than the first preset maturity.

[0022] Furthermore, the one-to-one or one-to-many relationship means that one blank number can correspond to multiple part numbers, but one part number can only correspond to one blank number.

[0023] Furthermore, when the part number in the forging and casting record information is the same as the part number of a forging and casting record information already in the database, the following matching is performed:

[0024] Determine whether the material brand, heat treatment status, single machine quantity and part digital model of the two forging and casting record information are consistent. If they are consistent, the newly generated forging and casting record information will overwrite the original forging and casting record information; if they are inconsistent, the new forging and casting record information will be assigned a blank number.

[0025] Furthermore, the blank number is assigned to the new forging and casting record information, specifically:

[0026] The material brand, heat treatment status, part digital model in the new forging and casting record information are compared with the forging and casting record information with the same part number. If the material brand and heat treatment status are different, a new blank number is assigned; if the material brand and heat treatment status are the same, the part digital model is compared. If the difference between the part digital models is within the preset range, no new blank number is assigned; if it exceeds the preset range, a new blank number is assigned.

[0027] Further, newly added forging and casting record information may be marked as newly added, and changed forging and casting record information may be marked as changed.

[0028] Furthermore, after the new blank number is generated, it is pushed to the 3D design platform and added to the part digital model.

[0029] Compared with the prior art, the present invention has the following technical features:

[0030] The present invention provides a forging blank design method based on maturity parallel design, which realizes the design of forging blank drawings, the review process, and after the closed loop, by defining structured attributes such as model, material grade, forging category, etc., with query, statistics, output, browsing and other functions, forging blank design realizes online process drive and improves design efficiency. At the same time, based on maturity early intervention, process design collaboration is realized, which is intuitive, efficient and accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0032] Model maturity is the identification of the perfect heat treatment status and detail level of the digital model in the design process, and is the basis for determining the use of data in the parallel design process. Maturity parallel design refers to the use of computer software and hardware technology and supporting environment, using the computer's digital calculation, logical judgment and reasoning functions to change the product serial mode, and taking the various stages of product development as a whole and integrated process. In the design stage, the upstream and downstream design, process, and manufacturing are coordinated and parallelized to achieve efficient full-process control of forging and casting blank design.

[0033] Compared with traditional offline control, the use of maturity-based parallel design management and process optimization can solve problems such as lack of control over the offline forging and casting blank design process, unclear projects, poor coupling with part design, long cycles, large workload for drawing signing, and difficulty in statistical analysis, and effectively improve the efficiency of forging and casting blank design work.

[0034] See attached Figure 1 The present invention provides a forging blank design method based on maturity parallel design, which carries out the forging blank design and approval process in the system, and realizes the full process system control of forging blank drawing design based on process drive. The specific steps are as follows:

[0035] Step 1: Identify the design requirements of forging and casting blanks.

[0036] Part data is obtained from the VPDM three-dimensional design platform, and the maturity and material grade are used as screening conditions to screen out part data that meets the preset requirements; wherein, the screening conditions are that the maturity is not less than the first preset maturity and the material grade is forging and casting; wherein, the maturity is the degree of completion of the part at different stages of the design process of the three-dimensional design platform. In this scheme, the maturity is divided into 7 levels, and its level is defined based on the degree of completion of the part digital model design. The first to third levels indicate that the part digital model is still in the skeleton stage; the fourth level part completes the preliminary digital model design and adds part information; the fifth level part digital model completes the detailed design and enriches the part information; the sixth level freezes the part information on the basis of the part digital model, including part number, material grade, heat treatment status, single machine quantity, machine model, and part digital model; the seventh level indicates that the part digital model has been designed and can be released. In this embodiment, the first preset maturity is the sixth level maturity.

[0037] A forging and casting database is established to store forging and casting record information and blank numbers, wherein the blank number and the forging and casting record information are in a one-to-one or one-to-many relationship, that is, one blank number can correspond to multiple part numbers, but one part number can only correspond to one blank number; the blank number is the code assigned to the blank to be the part, and multiple different parts can be processed through this part.

[0038] Generate forging and casting record information based on part data, where each forging and casting record information includes a part number, material grade, heat treatment status, single machine quantity, machine model, part digital model and other fields; store the forging and casting record information in the forging and casting database, and compare it with the forging and casting record information already in the database:

[0039] When the part number in the forging and casting record information is different from the part number of a forging and casting record information already in the database, the forging and casting record information is added to the database and assigned a blank number, specifically: the forging and casting record information already in the database is retrieved, and it is determined whether the material brand and heat treatment state of the forging and casting record information are the same as the existing forging and casting record information. If they are the same, it is determined whether the difference between the corresponding part digital models is within a preset range. If they are within the preset range, the blank number corresponding to the existing forging and casting record information is assigned to the new forging and casting record information, otherwise a new blank number is assigned to the forging and casting record information;

[0040] When the part number in the forging and casting record information is the same as the part number of a forging and casting record information already in the database, the following matching is performed:

[0041] Determine whether the material brand, heat treatment status, single machine quantity and part digital model of the two forging and casting record information are consistent. If they are consistent, the newly generated forging and casting record information will overwrite the original forging and casting record information; if they are inconsistent, the new forging and casting record information will be assigned a blank number, specifically: compare the material brand, heat treatment status, and part digital model in the new forging and casting record information with the existing forging and casting record information with the same part number. If the material brand and heat treatment status are different, a new blank number is assigned; if the material brand and heat treatment status are the same, the part digital model is compared. If the difference between the part digital models is within a preset range, no new blank number is assigned, and if it exceeds the preset range, a new blank number is assigned;

[0042] In the database, newly added forging and casting record information can be marked as added, and changed forging and casting record information can be marked as changed.

[0043] After the new blank number is generated, it can be pushed to the VPDM 3D design platform and added to the part digital model.

[0044] Step 2: Assign rough drawing design tasks.

[0045] For the forging and casting record information of the newly generated blank number, establish the development task of the forging and casting blank, set the designer and completion time, and push the development task to the designer.

[0046] Step three: carry out preliminary design of rough drawing.

[0047] The designer receives the task of developing forging and casting blanks and carries out forging and casting blank design based on the part digital model, process standards, technical standards, etc.

[0048] After completing the blank design offline, upload the preliminary designed blank drawing;

[0049] When the maturity of the part information corresponding to the forging and casting in the VPDM three-dimensional design platform reaches the second preset maturity, the blank drawing will be released. At this time, the approval personnel and distribution units are set up, and the formal approval process of the forging and casting blank drawing begins. The second initial maturity is higher than the first preset maturity. In this embodiment, the second maturity is set to the seventh level of maturity.

[0050] The present invention provides a forging blank design process and management method based on a maturity parallel design system. A forging blank design and approval process is established in the system, and structured attributes such as material information and task heat treatment status of a forging data set are defined and managed. Before the digital model of a design product is officially issued, the maturity parallel design system intervenes in advance to carry out process preparation and pre-design of the forging blank, thereby advancing the entire forging blank design and manufacturing process and improving the efficiency of model forging research and development. Based on the support of an information-based collaborative platform, the forging blank design process is optimized, and real-time tracking and control of the entire forging blank design process are achieved. Through a report component in the system, statistical output of information such as material grades, part numbers and blank numbers, blank drawings, etc. in the forging data set can be conveniently performed, and browsing within the system is supported, and output can be performed in multiple forms such as PDF and Excel tables.
