The practice of data modeling and ado skills in constructing modular specification parts

Design example ring screws are. When designing the standard parts interface, the interface should be considered to be simple and easy to use. At the same time, it must have certain data operation functions. It should also consider the uniform interface style of different standard parts. Write an application to generate a dynamic library file that can be executed below. This application mainly contains the following N parts; the data operation function part. Data operation functions mainly include data checking and modification. There are also some features for traversing data. These features are passed. Technology realized. Model update section. The model update part mainly uses the function to open the standard part prototype file and obtain the standard parts of the corresponding specifications. Other parts. This section includes two-dimensional map conversion functions, information about standard parts, and some auxiliary buttons.

With the provided secondary development interface, the dynamic library file generated by the compilation can be executed in the following two ways: the file format will be sent to the auto parts enterprise, and the latter will be produced according to the pull single organization. In the platform environment, how to import the pull list into the platform database system, so that more auto parts enterprises can query, obtain relevant information, participate in competition, and organize production, coordinate supply, etc., is an urgent problem to be solved. Networked resource management and optimized configuration technology The size of auto parts enterprises is different, and the hardware and software configurations are also different.

The construction of the networked manufacturing information resource library establishes a standard parts library, a device resource library, and the like. Data security for data security technology service platforms involves many aspects. One of them is how to ensure that the core data of the enterprise is not maliciously obtained by the outside world; in addition, how to avoid the non-malicious acquisition of other users' information by different users sharing the same host; these are technical difficulties. Conclusion The development of a model-based information public service platform is a feasible way for SMEs to informatize. Based on the informationization and resource integration of Guangxi Auto Parts Industry, the overall competitiveness of the auto parts industry will be enhanced.

Modifying a parameter value will automatically change the effect. The parametric design is powerful, and the parametric design methods of the parts mainly include: parametric modeling based on features and parametric design of sketches. In this database building method, the standard part model file should adopt the parameterized design method; an important module in the software is one of the secondary development programming language tools. As an interface to an external application, it is a collection of functions. Through programming, the user can achieve almost all the functions, developers can call these functions by programming in language, so as to achieve the needs of customization.

Although, it provides a rich, almost full function that covers all functions. But use these. Parametric modeling of functions is cumbersome. Drawing a simple 3D model often requires many functions to implement. Moreover, the modeling functions of different standard parts are different, and it is difficult to share the code. Therefore, the establishment of this system standard greatly reduces the amount of programming. The database link technology standard parts library contains huge amounts of data. Data access media mainly include data files and databases. Databases have significant advantages in handling large amounts of data. The system uses the database management system to realize the communication between the database and the application program is the focus of the research on the establishment of this standard parts library.

Precautions for use of graphite electrodes

1. According to the capacity of the electric furnace and the load of transformer, the grade and diameter of the electrode are suitable

2. When loading the electric furnace, the bulk charge shall be placed in the bottom of the furnace so as not to break the electrode. In the process of smelting, the lime should not be conductive. Large masses of objects are concentrated directly below the electrode, otherwise it will affect the electrode and even cause the electrode to break.

3. Attention should be paid to the position of the furnace cover. If the furnace cover is offset, the cover of the furnace will be blown on the lifting electrode, causing the electrode to be damaged.

4. When connecting the electrode, if the defect of joint bolt is found, the connection should be made after replacement

5. After the electrodes are connected, if there is a gap in the connection surface, it is important to find out the reason

6. The electrode should be used vertically.

7. The electrode holder shall be sandwiched between the upper and lower levels of the top electrode, and shall not be sandwiched between the warning line and the middle electrode. Otherwise, the electrode column is easily broken

8. The raw materials and production techniques of different manufacturers may vary. The physical and chemical properties of the electrode are also different, and it is recommended that the joints and electrodes produced by different manufacturers should not be used in a different way.
