文章对原20×2500四辊卷板机液压系统的原理进行了分析,针对实际使用中出现的下辊和两侧辊油缸中其中一液压缸活塞杆下爬、液压缸保压性不好等问题作了部分改进,取得了满意的效果。
In this paper, the principle of the original 20 × 2500 four-roll plate bending machine hydraulic system is analyzed. In view of the fact that the piston rod of one of the lower roller and the two side roller cylinders in actual use climbs down, The problems were partially improved and satisfactory results achieved.
