Datian process equipment life cycle management solution

process equipment is an essential production tool in the production and business activities of the machinery manufacturing industry. Process equipment is mainly composed of machine tools, production lines, molds, fixtures. What is the continuous progress of individual consumers' professional talents? It is the strong power to send a certain industry skills transformation, tools, measuring tools, auxiliary tools, station appliances, handling equipment, etc. The type, technical content and equipped quantity of process equipment are often related to product type, production equivalent and manufacturing quality, which directly reflect the technical level or manufacturing capacity of the enterprise in production and business activities. For ordinary machinery manufacturing enterprises, according to the product manufacturing process and production mode, it is often necessary to design, manufacture, use and maintain some process equipment. These process equipment mainly involve molds, fixtures and some cutting tools and measuring tools. Enterprises are generally referred to as process equipment, which is called tooling for short. Like products, tooling, in addition to coexisting with the associated product life cycle, also has a life cycle, that is, from design, manufacturing, use, maintenance to scrap, reflecting a complete life trajectory

I Tooling technology management background

the expression form of tooling is relatively complex. The technical content of tooling will directly affect the production efficiency and manufacturing quality of products. The technical characteristics of tooling generally include the following aspects:

l can be composed of one part or hundreds of parts

l can be a single mechanical structure or a combination of optical, mechanical and electrical structures

l it can be operated manually, mechanically, pneumatically or automatically

l the technical accuracy of parts or assemblies can be ordinary technical accuracy or precision technical accuracy

1. Classification of tooling

tooling is mainly used in the production and manufacturing process of products. The processing of parts and the assembly of products are almost inseparable from the use of tooling. Tooling plays an important role in ensuring product manufacturing quality and production efficiency. There are many kinds of tooling, and different kinds of tooling are used in different ways. Figure 1 shows the classification of process equipment

2. The design process of tooling

tooling design is often carried out at the same time as the product process is designed. The technical requirements of the tooling and the purpose to be achieved shall be proposed by the process designer, who shall design according to the requirements of the process designer and the product technical drawings and in combination with the conditions of the production site. Figure 2 is the basic flow diagram of tooling design

3. The main dilemma of tooling management

tooling design is one of the most cumbersome tasks in the daily technical work of enterprises. The quality and efficiency of tooling design directly affect the manufacturing quality, processing efficiency and time to market of products. However, there are many management problems and difficulties in the tooling design of enterprises, which are concentrated in the following aspects:

1) the synergy between tooling design and process design, tooling manufacturing

tooling design is a dynamic process, and the design scheme will change at any time. For the tooling design of new products, due to the technical instability of product structure and the uncertainty of product technology, it often brings inconvenience to the tooling design process. Tooling manufacturing belongs to single piece and small quantity production. During the manufacturing process, due to processing equipment or methods, the tooling structure needs to be changed for process adaptability. During the use of the tooling, the operator puts forward reasonable improvement opinions on the rationality and convenience of the tooling, which will have an impact on the replication of the tooling and even redesign. Therefore, tooling design changes dynamically with the change of product structure, process specification, production equivalent and so on in the whole product life cycle

2) unity of tooling design platform

some enterprises use design tools in tooling design, and there is the coexistence of two and three-dimensional CAD design. For fixtures, measuring tools, cutting tools and other types of tooling, two-dimensional design software such as AutoCAD, gs-icad, expected short-term scrap price consolidation and wait-and-see CAXA are generally used, and the generated engineering construction drawings and other documents belong to plane two-dimensional. For mold tooling design, three-dimensional design software such as proe, UG, CATIA, solid works, solid edge, etc. are often used, and three-dimensional modeling models and two-dimensional engineering construction drawings are generated at the same time. The isomerization of data types and electronic file formats brings great difficulties to data management

3) commonality and sharing of design resources

in order to reduce tooling costs, enterprises require a large number of standard parts and borrowed parts in the tooling design process. Due to the limitation of retrieval conditions, it becomes difficult to borrow parts, resulting in repeated design. Since the beginning of this year, the company has continued to maintain a growth rate of more than two digits. Frequent changes in equipment have brought about the consistency and effectiveness of versions, and the inconsistency between electronic data and paper drawings has also restricted the borrowing and utilization of parts. The scattered storage of part design data has caused more confusion in technical management

4) coordination of work flow

because the tooling is made of one piece, it needs to be changed frequently in the process of design and manufacturing. In addition, many links such as periodic verification, repair and scrapping need to be carried out in the life cycle of the tooling, which will involve many departments and personnel. The manual management process is cumbersome, difficult to track, and the work efficiency cannot be improved, making the technical management, production plan and progress management in an extensive state

5) cohesion of advanced management

due to the lack of effective management tools, various advanced management ideas of modern enterprises, such as concurrent engineering, agile manufacturing, collaborative innovation, etc., cannot be connected with tooling management, making it difficult to implement advanced management ideas and concepts, which has become a management obstacle to the further development of enterprises

6) complexity of organizational structure

the tooling design work of traditional machinery manufacturing enterprises, generally JTG E20 ⑵ 011 highway engineering asphalt and asphalt mixture experimental procedures are subordinate to the process department. With the intensification and deepening of enterprise reform, the traditional technology management
