The traction clamp 420 of the first traction device simultaneously clamps the rear ends of the plurality of profiles, and the traction drive member 440 drives the extrusion speed to be matched for traction.

When the extrusion length of the profiles reaches the requirement along with the progress of extrusion traction, the second traction device clamps a plurality of profiles at the same time in front of the first traction device. The sawing jig 240 clamps a plurality of profiles at the same time at the front side of the second traction device. At this time, the sawing jig 240 and the two pulling jigs 420 move backward at the same speed.

The clamping blocks 526 are respectively in one-to-one correspondence with the sectional materials.

After the two material handling clamps 520 respectively clamp the front and rear parts of the multiple sections of material, the first traction device and the second traction device respectively release the front and rear ends of the sections of material. The two traction clamps 420 are also driven by the translation driving member 470 to retract to the right side, and then move forward to clamp and traction the next section of profile. After the first traction device clamps the end of the next section of the profile again, the sawing jig 240 releases the profile. After the sawing fixture 240 loosens the section bar, the sawing fixture 240 is driven by the sawing fixture translation driving member 470 to move to the left, so that the space above the extrusion conveying line 100 is avoided, and the traction saw 200 of the next section bar is waited to cut.
