China's auto panel dies in New Development – china Steel Structure Buildings
Automobile mold manufacturing enterprises in recent years, technological advances seen in the following aspects.
Equipment level has been greatly improved
In recent years, both through the technological transformation of the new business or old business, without exception, have the bulk purchase of the advanced numerical control equipment, which included a three-axis to the five-axis high-speed machine tool, large gantry-type machining centers and CNC milling and other machine tools, advanced measurement and debugging of large-scale equipment and multi-axis CNC laser cutting machine.
At present, many companies already have a mold about 10 sets of large-scale numerical control equipment, some companies already have more than 30 units. Currently, the industry has some large-scale numerical control processing equipment more than 400 sets, therefore, production of automotive panel die level and capacity has greatly improved. In the past, an enterprise is difficult to model within a year to complete the mold, and now the focus of some key enterprises have fully have this capability. Of individual enterprises through industry collaboration also has a year and be completed simultaneously within a 4 to 5 cars full mold capacity. Most of the enterprises also equipped with many advanced software. According to the present level of equipment to see, the domestic already have a year to complete more than 20 vehicle models die capability.
Design and processing technology have greatly improved
In recent years, companies use 3D CAD that has been more and more, and some enterprises have already reached 100% of applications. At the same time, CAE technology has been widely used. On the one hand the introduction of CAE software from abroad, after a second development, the application has been greatly improved; the other hand, is the self-developed with independent intellectual property rights, advanced CAE software, has also been successfully applied in production. CAE software is now applied mainly to introduce the LS, DYNA3D, DYNAFORM, PAMSTAMP, OPTRIS, AUTOFORM and domestic self-developed VFORM, KMAS, sheetForm and CADEM systems. As a major automotive panel die in the Development of CAE technology, core technology, the current CAE software has been forming in the traditional analysis only for the realization of an upgrade, to participate in the entire process of stamping process, the analysis of the breadth of the content, practicality, precision both in terms of significant progress. This product design and process analysis to improve mold remarkable is the success rate of drawing dies and shorten the mold manufacturing cycle and improve quality of mold have a significant role. Digital manufacturing, reverse engineering, concurrent engineering, agile manufacturing, lean production and other advanced technologies in the production of automobile panel dies has been applied, and produce good results. Widely used in the mold factory CAPP although very difficult, but also some successful examples. Previously little used in high-speed machining technology is now being adopted more and more and more can be said to have reached the stage have been widely applied. Put a wealth of experience in mold design, standards and norms and CAD / CAM technology, systems integration and automation of intelligent all-round (from the data to the products) mold design and processing solutions for the software has begun to be applied, and effectively improve the quality and shorten the die mold production cycle.
Not long ago, a group of study in the United States and Canada, and practitioners in the U.S. auto industry die technical staff for many years set up in Chongqing, DSI Digital Modeling System (Chongqing) Co., Ltd., to create and use the digital-mode technology. The technology relies upon an advanced mold and stamping process design and simulation techniques combined mold expert systems, will promote the traditional mold of domestic computer technology as a way to support change in the direction of the mold construction process, to shorten the production cycle and reduce the cost of mold , will play a very good role. There are also some enterprises have realized the CAD / CAE / CAPP / CAM integration, so as to enhance the enterprise's comprehensive level. Other areas such as measurement techniques, surface coating technology, a comprehensive inspection with tooling, standardization, applications, and rapid prototyping technology with the successful combination of rapid economic mold and so on, in recent years has also made a lot of progress. A number of key enterprises and foreign-funded enterprises in China established a number of wholly owned or joint-venture automobile panel dies design and R & D center, some enterprises with foreign related companies jointly develop and co-design, which is also the industry's technological progress has created favorable conditions for .
Mold levels have greatly improved
As the equipment level and design and processing technologies, coupled with the improvement of the quality of personnel and a number of new technologies in recent years, the level of domestic automobile panel dies also will be greatly improved. Raising the level of mold is multifaceted, reflected in the mold of the entire process. Over the past can not be produced molds are now able to produce, and this also reflects a higher level. Now, including the difficult and the overall side-Wai and fenders mid-range cars, including all the coverage of mold have been able to produce internally. For joint ventures abroad, molds, and some models supporting the export molds, you can also abroad (such as Japan, Germany), the company's standards for acceptance.
Some domestic enterprises have realized the key from the local parts and components, middle and low car over to the vehicle spare parts mold, the mold production capacity of high-end cars. Supporting large-scale press and automation continuous-mode and multi-position progressive die is now the country will also have a relatively high level products. Levels of domestic and foreign high-end mold gap is narrowing. High-grade sedan mold to rely on imports of the phenomenon is a gradual change. In recent years, automated production line for the coverage of mold and large-scale multi-site also explains the emergence of automated die mold technology, comprehensive level of quality and strength progress.
