Application of Radial Arm Drill---Original ZJ Brand
1. The Radial Arm Drill is a large hydraulic radial drill developed by our company. The hydraulic system of the Radial Arm Drill consists of two parts: the hydraulic system of the control mechanism and the hydraulic system of the clamping mechanism. The control valve and the preselection valve are installed on the upper part of the headstock. The spindle speed preselection valve and the feed volume preselection valve are 16-position six-way rotary valves. Each rotary valve controls four differential cylinders to achieve 16-level speed conversion. The control valve is a five-position six-way rotary valve, which controls the forward rotation cylinder, the reverse rotation cylinder, the shift cylinder, the neutral cylinder, and the brake cylinder. During the shifting process, high-pressure oil enters the preselection valve, which pushes the shifting cylinders to drive the sliding gear to shift. At the same time, the forward-rotating cylinders also enter the high-pressure oil through the small holes, because the areas of the forward and reverse cylinders are not equal (forward rotation is greater than reverse rotation). Turn), so that the shift fork that compresses the friction plate has a smaller force to compress the forward rotation friction plate, so that the
transmission chain can be started.
