With the continuous development of economy and technology, the automobile has become one of the necessary tools for people to travel. The large demand of the consumer market also promotes the rapid development of the automobile industry. The technology of automobile mold has become the main force for the development of the automobile industry.
The mould is a technical product and a typical unshaped product. Mold manufacturing enterprises are typical single piece manufacturing enterprises, each set of mold must carry out creative design, numerical control programming, production preparation, mechanical processing, assembly and impact test, increasing the complexity and difficulty of enterprise production management. How to improve the production efficiency, shorten the development cycle, improve the level of die technology and reduce the production cost has been a difficult problem faced by die enterprises.
Implement concurrent engineering in the whole process
Implementing concurrent engineering in the whole process is one of the most effective ways to shorten the mould development cycle. The so-called concurrent engineering is that each working procedure and each link in the process of mold development should be synchronized, parallel and cross, so as to avoid serial. In the development of automobile body, there are two stages of synchronous engineering.
The first stage is the concurrent engineering in the later stage of product development and the earlier stage of mold development of the r&d department. In other words, before the car body mathematical model is frozen, the product r&d department USES the design version of the car body mathematical model and the technical department of the die factory to conduct design review and process countersigning, so as to improve the product development. At the same time, the mold factory USES the design edition digital model to carry on the mold development plan plan, the development budget, the plan and the stamping process plan ', carries on the DL drawing design, carries on the drawing die preliminary design and the casting solid mold processing. The concurrent engineering in this stage can shorten the development time of mold by 1 ~ 2 months.
The second stage is the parallel engineering between the technical preparation, production preparation, mold processing and debugging in the process of mold development, that is, production preparation, processing technology and numerical control program design. The production plan must first arrange drawing and forming molds, then flanging and finishing molds, then trimming and punching molds, and finally blanking and punching molds. Only in this way can the balanced production be achieved and samples can be provided to the automobile factory in advance to facilitate the concurrent engineering in the third stage. The third stage is the late mold development and model test, test and body fabrication line debugging of concurrent engineering, the question of the drawing, molding, flanging after the completion of the good use of five-axis CNC laser cutting machine to finish blanking, trimming, punching and other processes, provide stamping samples, assembling screw body, fitting, reliability design, validation experiments, automobile product announcement, debugging fabrication lines, etc., until you can small batch trial production, market development. Generally, it takes 4 to 6 months to complete this part of the work. The mold manufacturer can fully utilize this period to complete the development of trimming, punching and blanking molds, and adjust all the molds to the commercial state.
