I. overview
Since the reform and opening up, with the rapid development of the national economy, the market demand for hollow blow moulding machine is increasing.
In recent years, the industry of hollow blow moulding machine has been growing rapidly at a rate of about 15%. The ownership of hollow blow moulding machine industry enterprises has also undergone tremendous changes. In addition to state-owned professional hollow blow moulding machine factories, the collective, joint venture, sole proprietorship and private sector have also developed rapidly.
With the acceleration of international integration and the intensification of market competition, people have increasingly realized the importance of product quality, cost and product development capability. The manufacturing of hollow blow moulding machine is one of the most basic elements in the whole chain. The manufacturing technology of hollow blow moulding machine has become an important symbol to measure the level of a country's manufacturing industry, and to a large extent determines the survival space of enterprises.
In recent years, many hollow blow moulding machine enterprises have increased their investment in technological progress, and regard technological progress as an important driving force for the development of enterprises. Some domestic hollow blow moulding machine enterprises have popularized two-dimensional CAD, and have begun to use UG, Pro/E, I-DEAS, Euclid-IS and other international common software. Some manufacturers have also introduced Moldflow, DYNAFORM, Optris and MAGMASOFT and other CAE software, and successfully applied to the design of stamping die.
The manufacturing technology of large-scale stamping hollow blow moulding machine, represented by automobile panel hollow blow moulding machine, has made great progress. Some automobile panel hollow blow moulding machine manufacturers such as automobile company hollow blow moulding machine factory have been able to produce some automobile panel hollow blow moulding machine.
In addition, many research institutes and colleges carry out the research and development of hollow blow moulding machine technology. After years of efforts, notable progress has been made in the CAD/CAE/CAM technology of hollow blow moulding machine, which has contributed to improving the quality of hollow blow moulding machine and shortening the design and manufacturing cycle of hollow blow moulding machine.
II. Development Trend of Manufacturing Technology of Stamping Hollow Blow Molding Machine in the Future
The development of hollow blow moulding machine technology serves the requirements of "short delivery time", "high precision", "good quality" and "low price" of hollow blow moulding machine products. To meet this requirement, it is urgent to develop the following contents:
1. Promote CAD/CAE/CAM technology in an all-round way
CAD/CAE/CAM technology of hollow blow moulding machine is the development direction of design and manufacture of hollow blow moulding machine.
With the development and progress of computer software, the conditions for popularizing CAD/CAE/CAM technology have basically matured. Enterprises will increase the training and technical services of CAD/CAM technology, and further expand the application scope of CAE technology. With the development of computer and network, it is possible to popularize CAD/CAE/CAM technology across regions, enterprises and institutes in the whole industry, to integrate technical resources and to make virtual manufacturing possible.
2. High Speed Milling
High speed milling developed abroad in recent years has greatly improved the processing efficiency and achieved a very high surface finish.
In addition, it can also process high hardness modules, and has the advantages of low temperature rise and small thermal deformation. The development of high-speed milling technology has injected vigor into the manufacturing of large-scale cavity blow moulding machine in automobile and household appliances industry. At present, it has developed towards higher agility, intelligence and integration.
3. Scanning and Digital System of Hollow Blow Molding Machine
The scanning system of high-speed scanner and hollow blow moulding machine provides many functions from model or object scanning to processing desired model, which greatly shortens the development and manufacturing cycle of hollow blow moulding machine.
Some fast scanning systems can be quickly installed on existing CNC milling machines and machining centers to achieve rapid data acquisition, automatic generation of various CNC system processing procedures, different formats of CAD data, for the hollow blow moulding machine manufacturing industry "reverse engineering".
Scanning system of hollow blow moulding machine has been successfully applied in automobile, motorcycle, household appliances and other industries, and it is believed that it will play a greater role in the future.
4. EDM Milling
EDM milling technology, also known as EDM generation technology, is a new technology to replace the traditional processing cavity with shaped electrodes. It is a high-speed rotating, simple, tubular electrodes for three-dimensional or two-dimensional contour processing (like CNC milling), so it is no longer necessary to manufacture complex shaped electrodes, which is obviously a major development in the field of EDM. Exhibition. Overseas, machine tools using this technology have been used in hollow blow moulding machine processing, and it is expected that this technology will be developed.
5. Improve the Standardization of Hollow Blow Molding Machine
The standardization degree of China's hollow blow moulding machine is constantly improving. It is estimated that at present, the coverage rate of standard parts of China's hollow blow moulding machine has reached about 30%, and that of developed countries is generally about 80%.
6. High-quality materials and advanced surface treatment technology
It is necessary to select high quality steel and apply corresponding surface treatment technology to improve the service life of hollow blow moulding machine. Heat treatment and surface treatment of hollow blow moulding machine are the key links to give full play to the properties of steel materials of hollow blow moulding machine.
Vacuum heat treatment is the development direction of heat treatment for hollow blow moulding machine. In addition to improving the existing technology, the surface treatment of hollow blow moulding machine should develop advanced technologies such as vapor deposition (TiN, TiC, etc.) and plasma spraying.
7. Grinding and polishing of hollow blow moulding machine will realize automation and intellectualization
The surface quality of the hollow blow moulding machine has great influence on the service life of the hollow blow moulding machine and the appearance quality of the parts. It is an important development trend to study automatic and intelligent grinding and polishing methods to replace the existing manual operation in order to improve the surface quality of hollow blow moulding machine.
8. Development of Automatic Processing System for Hollow Blow Molding Machine
This is the goal of our long-term development. The automatic processing system of hollow blow moulding machine (FMC and FMS) should have a reasonable combination of multiple machine tools; equipped with follow-up positioning fixture or positioning plate; complete CNC Library of tools and tools; complete CNC flexible synchronization system; quality monitoring and control system, etc.
