TDG Series Directly Forming to Square and Rectangular Tube Mill Only one set of rollers can be continuously produced within a certain range of rectangular steel pipe, using the international advanced multi-radius combination molding process and high-frequency welding, forming by multi-channel symmetrical bending. It can be divided into small side bending, boardside bending, free bending at closed side, high frequency welding, precision straightening, produce the exact size and good quality pipe after cut off.

Characteristic：
One set mold roller can produces a range of rectangular tubes.
This machine has characteristics such as no replace spindle, no remove roller stand and quick change rollers.
Save mold, save time.
Four square corner deformation part which can save extra deformation process then save energy consumption and equipment load.

Milling Type Flying Saw Introduction

The milling type flying saw is used on the welded pipe tube mill line for continuously cutting big-size round pipes square and rectangular pipes into specific length when the production line running.

The pipe is length cut by 4/2 milling disk cutting head.We use 4/2 milling heads to finish cutting along with outer contour line.We adopt two blades for cutting 219 pipe(The diameter of round pipe,the diagonal of square and rectangular pipes).

The numerical control system calculates trolley’s start-up point,acceleration curves,deceleration curve,maximum return speed and also displays the running curves of the trolley to ensure the system running at a good state.The position and speed of the trolley are measured by a incremental encoder which is installed on the trolley’s drive motor.Along with the rotation of drive motor,the measuring value is sent to numerical control system to precisely control the cutting position from drive to pipe.During the cutting process,the velocity fluctuation of pipe has no effect to the control precision.The copying cuting contour line can be set up on touch screen which has round,square and rectangle three interface figure.The intuitionist and easy operation make the complicated cutting curve be set up by simply figure parameters.
