　　Advanced small pipe punching machine, Jingheng tunnel support small pipe forming machine

　　Punching machines have been widely used in tunnel construction. The punching machine can set 200 holes on one pipe, and the machine is matched with a servo motor. The hole spacing error is within ± 0.3mm, and the punching speed is fast, which greatly improves the manual cutting speed compared to before. The circular holes are also relatively neat and beautiful.

　　When processing the small conduit, the steel pipe is parallel to the centerline of the lining and driven into the surrounding rock of the arch at an angle of 8-14 °. The circumferential spacing between steel pipes is 40cm. After each row of steel pipes is completed, the advanced small conduit needs to be injected with cement slurry. After reaching 75% strength, the arch is excavated and initial spraying and steel frame are erected. After the initial support is completed, a row of steel pipes is laid every 2.40m, and the advanced small conduit maintains a lap length of at least 1.0m. In order to overexcavate, the angle of the advanced small guide pipe should be controlled. At the same time, except for the advanced small guide pipe, all other advanced small guide pipes must pass through the belly of the steel frame and be welded to the steel arch. That is, it is required that the steel arch frame be perforated at the position of the steel web plate during the manufacturing process. The advanced small guide pipe punching machine is used to form the precise tunnel support small guide pipe.

　　Material power: Adopting a high torque AC synchronous servo motor, it has the characteristics of fast response, high positioning accuracy, low noise, small braking heat loss, and long service life. Motion control: Equipped with advanced controllers and touch screen operation, it is simple and convenient. 1. Punching and cutting can be processed simultaneously, and simple punching or cutting can also be achieved. 2. Four pipes can be flushed at the same time, and the speed can reach three holes per second; 3. Double sided holes and single sided holes can be punched on one pipe, and two workstations can be controlled simultaneously or separately; 4. Adopting a user-friendly human-computer interaction interface, no personnel programming is required, and the hole spacing is directly input on the touch screen. The punching distance can be controlled to be equidistant or non-uniform, with a punching accuracy of 0.05 millimeters; 5. The system automatically records the punching quantity and cumulative punching quantity of each shift; An automatic cutting system can be added according to customer requirements, which can simultaneously perform automatic punching and cutting work. The advanced small pipe punching machine and the Jingheng tunnel support small pipe forming machine can be used.
