Application of servo stamping production line in Guangqi Honda
Metal Processing Online specializes in the "Advanced Stamping Sheet Metal Process and Equipment" theme forum, inviting those who are the latest technology in the industry to express their opinions on the latest developments and applications of stamping sheet metal technology, equipment and processes, and showcase the stamping sheet metal industry. Status and development trends. In 2011, Guangqi Honda has expanded the capacity of 240,000 units in Huangpu and Zengcheng. The servo press line I talked about was built at the Zengcheng plant. In 2010, in the investigation of the stamping field, Guangqi Honda locked in the advanced process technology of servo stamping. For the whole vehicle stamping field, how to use the smallest resources to achieve maximum production efficiency, so that high-quality products can be manufactured? Consider two points: First, from the perspective of product competition, the meaning of product competitiveness means that the shape is more and more complicated, and the requirements for drawing and stamping are getting higher and higher. The application of high-strength steel plate can further increase the weight of the body. Lighten, there are products that are highly attractive and low-cost in terms of materials and design. Secondly, in the field of stamping, mass production is guaranteed to ensure high-quality products, which is a key factor in improving production efficiency. Guangqi Honda has also gained some experience from the industry. In terms of servo stamping, the new generation of press lines should have the following characteristics: drawing depth, forming complexity and application of high-strength boards; capable of achieving the required materials through materials and forming properties. The grade, so that the material cost is reduced; the ideal production mode can optimize the movement of the press, the movement of the mold and the transfer trajectory between processes, and improve the production efficiency. In order to meet the requirements of the servoization of the slider, the servoization of the cushion, the rapid replacement of the mold, and the improvement of the conveying speed, the structure of the new stamping servo production line has been set. The whole structure consists of: demolition, cleaning, and quick centering device. Four presses in the middle (23 000 kN, 12 000 kN, 10 000 kN), all presses are servo controlled. The transportation device between the operations, Honda, and Honda Co., Ltd. cooperated to realize automatic packing, thereby reducing the labor intensity of personnel. From the perspective of energy saving and quality, the cost rate of materials is increased. After the upper and lower molds are contacted and formed, the production cycle of the mold is ensured, and the precision and the noise of the stamping process are controlled in time. The speed of the slider in the non-machining area is very fast. After the contact with the mold, the servo pad can form a good interaction with the slider. The pre-acceleration can make the performance in the forming process better. In the characteristics of this servo press line, the parameter input between the servo press speed and the cushion is simulated by the optimization software to form the optimal forming mode. After the hydraulic system outputs to the product, these optimal data can be reversed to the press forming conditions. Go in. Finally, the data can also become a management basic database for the entire control aspect. In the future, the new model mold development process will fully consider these processing parameters, and then set the optimal mold. Specifically, a forming condition, the part of the two presses and the optimization of the action mainly refers to the transfer between the processes, through the integration of the equal-line control software, the conditions are set optimally, and the data can be developed in the new model. For some applications, during the development of new models, according to some characteristics of the mold, the best transfer mode is obtained. In terms of production process, the speed of the servo press is re-controlled to improve the flow of the material, and the level of drawing is improved compared to the conventional mechanical press mode. Further through the simulation of the software, as well as the setting of the transfer room, it will greatly help the entire mold debugging and production automation debugging. In general, the traditional mechanical line beat 12SPM, 2SPM can be improved by servo press stamping technology, 2SPM can be improved by the optimization of mold transfer, and the optimization of the whole line control can finally achieve the production speed of 18SPM. With integrated servo line effect, the forming performance is improved by 20%. Through the increase of efficiency and material cost (10%), the production line capacity can be increased by 50%. Compared with the traditional mechanical line, the servo line reaches 32% in terms of energy saving. However, it is necessary to further improve the cycle of the production line, and it is also inseparable from the mold. In the mold, we also hope to have in-depth communication with the industry, so that this production line can be better played. Jiangsu Jiajie Special Screw Co., Ltd , https://www.tzbolts.com
