[0002] The pipe force valve is a control element used in a hydraulic system, mainly used for adjusting and controlling the direction, flow and pressure of liquid. In the production of the pipe force valve, multiple holes are usually punched on the pipe force valve for the convenience of cooperation and installation.

[0003] The pipe force valve structure needs to communicate the inclined branch pipe and the vertical branch pipe on the circumferential side wall of the valve body, and needs to punch holes at the end of the inclined branch pipe and the end of the vertical branch pipe. When punching the end of the inclined branch pipe on the pipe force valve, some manufacturers usually adopt the method of hoisting the pipe force valve and making the end of the inclined branch pipe horizontally upward due to the difficulty of turning the pipe force valve with manpower because of the large diameter of the pipe force valve. However, in order to adjust the pipe force valve to the end of the inclined branch pipe horizontally upward, the pipe force valve needs to be repeatedly adjusted and hoisted, which is troublesome. Referring to the Chinese patent document with the publication number CN217858885U and the name of a punching device for valve processing, the top of the processing table is provided with a drilling machine for drilling operation, the processing table is provided with a semicircular pipe, the inside of the semicircular pipe is provided with a placing arc-shaped groove for the workpiece, the two ends of the outside of the semicircular pipe are provided with fixing mechanisms for fixing the workpiece, and one end of the semicircular pipe is provided with an adjusting mechanism for adjusting the angle of the semicircular pipe. In work, the fixing mechanism fixes the workpiece in the semicircular pipe, and the adjusting mechanism rotates the semicircular pipe, so that the drilling machine can better drill the side of the workpiece.

[0004] Referring to the above technical solution, the above solution can only process the holes of the end of the vertical branch pipe perpendicular to the circumferential side wall of the pipe force valve, and cannot process the holes of the end of the inclined branch pipe. Therefore, the method of repeatedly hoisting and adjusting the pipe force valve is still needed to process the holes of the end of the inclined branch pipe, which is troublesome. SUMMARY
