Cut the running steel tube into the following runout table. When the continuous working rolling mill delivers the steel pipe to the flying saw, the saw car tracks and synchronizes with the pipe speed, the clamp block clamps, and the two saw cutting systems installed on the rotary table with the saw blade rotation, which makes radial feed under the drive of the feed ac servo motor.At this time, the rotary table is also rotating, and the saw cutting system makes compound movement between the rotary table and its own feed, and cuts the steel pipe along the section shape track of the cut piece.Then the systems relax back into place and wait for the next working cycle.The cutting feed use polar coordinates type. equipment composition: Body system, sawing machine, driving system, rotary disk system, feed system, jig, roller device, speed measurement device, hydraulic system, control system

electric parameters:
Function description: Counting, palletizing:After the number of steel pipes reaches the specified number, the entire layer of steel pipes will be sent to the material frame by the layer sucker mechanism, according to the set package type, after the stacking is completed, the entire package of steel pipes will be transported to the packing rack. Strapping:The package transfer roller table is started, and the whole package of steel pipes are moved out of the palletizing station and transferred to the strapping station; automatic packaging and welding are completed, and the water is controlled at the same time. Traverse:The side rollers are opened, and the bundled steel pipes are removed. Reach the weight measurement position. cycle:After the whole package of steel pipes are removed, the lifting platform returns to the receiving position and waits for the stacking of the next package of steel pipes. The stacking connection between each package of steel pipes realizes seamless docking to ensure the continuity of work. The electrical control adopts PLC program control, touch screen (PLC adopts German Siemens), realizes man-machine dialogue, can freely switch between manual and automatic, and the electrical components use Delixi brand. In the program, you only need to input the number of steel pipes per layer, the number of layers of each bundle of steel pipes and the necessary parameters. After adjustment, the baler will automatically stack the required complete package of steel pipes.
Note: After the device is automatically reset to zero every time it is started, it performs a self-check. After the device is in a normal state, it can be officially operated.
