板材成型液压机滑块快速回程控制系统关键技术研究

Research and application of key technology of the quick return control system of the slider of the hydraulic press for sheet metal forming

传统板材成型液压机广泛应用于汽车覆盖件及其他类型金属板材件的生产,有价格低廉但生产节拍相对较慢的特点。传统板材成型液压机一般采用油泵及电磁阀阀控控制系统驱动滑块回程,回程速度受制于油泵排量及控制系统的响应速度。随着汽车生产工艺的不断改进,传统板材成型液压机市场竞争日趋激烈,在不增加液压机成本的前提下提高生产节拍,无疑将大大提高产品的性价比及竞争力。经过深入研究板材成型液压机的每一个工艺动作,研发新一代滑块快速回程控制系统对提高设备生产节拍意义重大,在提高设备生产效率的同时兼顾节能环保与安全,将大大提升板材成型液压机的竞争力。

The traditional hydraulic press for sheet metal forming is widely used in the production of automobile panel and other types of metal panel.It has the characteristics of low price but relatively slow production time.The traditional hydraulic press for sheet metal forming generally uses the control system of oil pump and solenoid valve to drive the slider return,and the return speed is subject to the displacement of oil pump and the response speed of control system.With the continuous improvement of automobile production technology,the market competition of traditional sheet metal forming hydraulic press is increasingly fierce.Without increasing the cost of hydraulic press,improving the production beat will undoubtedly greatly improve the cost performance and competitiveness of products.After in-depth study of each process action of the sheet metal forming hydraulic press,it is of great significance to develop a new generation of slider fast return control system to provide equipment beat.It will greatly improve the competitiveness of the sheet metal forming hydraulic press by improving the production efficiency of the equipment and taking into account energy conservation,environmental protection and safety.
