Post tension metal corrugated pipe making machine spiral round duct forming machine

KJ130 series spiral duct machine a kind of equipment for producing pre-stressed concrete reserved tunnel metal bellows makes the galvanized steel strip coil into double wave shape then undercuts and swages to apply the bellows, Which With high efficiency and Small volume,  Easy operation and maintenance, convenient and speed adjustable. It is suitable for centralized use at construction sites and factories.

1. Take the 0.23-0.4mm 36mm steel strip into the sink containing the latex oil, and then pass the guiding belt to control the direction of steel strip.

2. Enter the four-component roller, press the mold into a double wave with a semicircle, Fold the left up, the right side is folded downward, and the shape is folded on the die, the wheel is pressed by the flanged wheel to press the wheel. The upward folding and the downward folding edge are fastened, so that the indentation of the straight tooth embossing wheel is bilaterally engaged, and the compacting wheel is compacted to form a tightly interlocking bellows,

3. continuous winding is extended to reach the required length. When the front end of the tube contacts the travel switch, the main motor will automatically stop

4. cut off with a cutter to complete the production of a tube.
