　　Slope support small pipe punching machine, precision seamless steel pipe 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.

　　Construction parameters for small conduits

　　The determination of various parameters for advanced small conduit construction should be based on the geological conditions of the surrounding rock boundary, the condition of the surrounding rock, the form of the support structure, and the size of the tunnel section. Generally, advanced small conduit construction is set within a 120 degree range along the excavation contour line. In general, the length of the small conduit is L=the height of the upper step+2m. The diameter of the small conduit is 38-50mm. The front section of the small conduit is made into a conical shape about 10cm long, and a steel reinforcement hoop with a diameter of 6-8mm is welded at the tail end. The external insertion angle is generally controlled between 10 degrees and 15 degrees. The grouting pressure is controlled at around 2MP. The diffusion radius of the slurry is generally 0.5m. The grouting speed is controlled at 50-100L/min. The overlap length of each cycle of small conduits is controlled within 1m. Slope support small conduit punching machine, precision seamless steel pipe small conduit forming machine.

　　Characteristics of advanced small pipe punching machine:

　　1. We use original Schneider servo motors and control components exported from Germany, as well as fully digital signal processing components and operation components controllers independently developed by our factory.

　　2. Adopting touch screen display and operation interface, it is easier to stop data operations (freely output multiple sets of hole distances and numbers).

　　3. Punching pressure and fixture pressure are adjustable, suitable for punching pipes of different thicknesses, half hole can be freely selected, full hole function, adjustable feeding and receiving speed, and reliable workpiece positioning fluctuation.

　　4. Used for fully automatic CNC punching machines, the mold adopts a common design method, and the secondary components include export material manufacturing, sleeve bearing guidance, workpiece support with bearing plates to ensure workpiece degree, ineffective maintenance of the mold, enhanced lifespan, smooth punching of the workpiece, no burrs, no scratches, and no jamming.

　　5. The oil cylinder task adopts pulse control, which enables the oil cylinder to have the characteristics of high-speed descent, low-speed punching, and high-speed return. It can effectively reduce the fluctuation of workpiece forming during punching, reasonably reduce the task load of the motor, and achieve energy-saving effects. The slope support small pipe punching machine is a precision seamless steel pipe small pipe forming machine.
