我厂在生产钢木家具中,每年约需不同规格的U 型管件十多万件。为适应生产需要,我厂自行设计制造了一台可以弯制各种规格U 型管的液压弯管机,图1为工作部分简图,图2为液压系统原理图。启动电机后,将手动换向阀3推向右位,泵输出的压力油经阀3、转阀4及延时阀7,推动液动换向阀6至左位,于是缸杆带动工作台前进,到位后撞动拨叉;使阀4转至右
I plant in the production of steel-wood furniture, about a year of different specifications of the U-tube more than one hundred thousand pieces. In order to meet the production needs, I designed and manufactured a factory can bend a variety of U-tube hydraulic pipe bending machine, Figure 1 for the working part of the diagram, Figure 2 Schematic diagram of the hydraulic system. After starting the motor, push the manual reversing valve 3 to the right position, and the pressure oil output by the pump passes through the valve 3, the rotary valve 4 and the delay valve 7 to push the hydraulic reversing valve 6 to the left position, and then the cylinder rod drives the workbench to advance , When in place, hit the fork; turn valve 4 to the right
