Referring to fig. 5 and 8, a synchronization mechanism 6 for driving the plurality of forming concave rollers 21 to synchronously rotate is further arranged on the 匚 -shaped mounting plate 2, the synchronization mechanism 6 comprises a double-shaft motor 61 and a synchronous belt 62, two ends of each forming concave roller 21 are respectively provided with an extension shaft 22, two extension shafts 22 respectively penetrate through the 匚 -shaped mounting plate 2 and are respectively provided with a driven wheel 23, the double-shaft motor 61 is arranged at the center of the bottom of the 匚 -shaped mounting plate 2, two ends of the double-shaft motor 61 are respectively provided with a driving wheel 611, and the driving wheels 611 are in transmission connection with the corresponding plurality of driven wheels 23 through the synchronous belt 62.
In order to ensure that the D-shaped heat exchange tube is completely machined, the double-shaft motor 61 is arranged, and the double-shaft motor 61 drives the plurality of forming concave rollers 21 to synchronously rotate through the two synchronous belts 62, so that the D-shaped heat exchange tube can be continuously pulled, the plurality of forming concave rollers 21 synchronously rotate, the same traction force applied to the D-shaped heat exchange tube during movement can be ensured, and the reduction of forming effect caused by different traction forces is avoided.
Referring to fig. 1 to 3, the guide mechanism 5 includes a guide frame 51 and a guide motor 52, the guide frame 51 is vertically disposed on the table 1 and located at a side of the gantry 11 far from the vertical plate 13, a fixed concave roller 511 is rotatably disposed in the guide frame 51, the guide motor 52 is disposed on an outer wall of the guide frame 51 and is used for driving the fixed concave roller 511 to rotate, pressing through grooves 512 are further disposed on inner walls of two sides of the guide frame 51, a pressing block 513 is slidably disposed in each pressing through groove 512, a sliding concave roller 514 is rotatably disposed between the two pressing blocks 513, a pressing spring 515 is disposed at a top of each pressing block 513, and the pressing springs 515 are located inside the corresponding pressing through grooves 512.
Under the elastic force of the pressing spring 515, the sliding concave roller 514 can be contacted with the outer wall of the round tube to be processed, pressing force is applied to the round tube to be processed, the round tube can be attached to the fixed concave roller 511, the fixed concave roller 511 can rotate along with the rotation of the guide motor 52, the round tube to be processed can move towards the direction close to the vertical plate 13 along with the rotation of the fixed concave roller 511, the round tube to be processed can be processed into a forming cavity, the D-shaped heat exchange tube can be pulled after the processing is completed, the D-shaped heat exchange tube can be moved out of the forming cavity, the D-shaped heat exchange tube can be subjected to secondary extrusion forming, and the forming effect is further improved.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
