同步挫制方式折弯液压机主要用于板材折弯成形加工,其结构原理如图1所示。液压机两侧液压缸间的距离较大(小型的也有二米),加压时活塞下降会发生不同步现象,即使滑块的导向部分精度高、刚性好,也会降低制件的加工精度。随着机械工业水平的不断提高,对于板件加工精度的要求也愈高。为此,对折弯液压机的各种驱动方式、同步补偿装置等进行了研究,并得到了适当的方法。在活塞下降过程中检查出两侧液压缸的位差,为消除位差,将位差
Synchronous restraint mode bending hydraulic press is mainly used for sheet metal bending forming process, the structural principle shown in Figure 1. Hydraulic machine hydraulic cylinder on both sides of the larger distance (small also have two meters), when the piston pressure drop will occur out of synchronization phenomenon, even if the guide part of the slider with high precision and good rigidity, will reduce the workpiece machining accuracy. With the continuous improvement of the level of machinery industry, the higher the machining accuracy requirements of the plate. For this reason, various driving methods of a bending hydraulic press, a synchronous compensation device, etc. have been studied, and an appropriate method has been obtained. Pistons in the process of lowering the hydraulic cylinder on both sides of the check-bit difference, in order to eliminate the bit, the bit will be poor
