The hydraulic cylinder 52 will drive the mounting plate 4 to descend, the rack 63 will correspond to one of the blank spaces 642 and drive the gear to rotate, the gear will engage with one of the latch units 641 and cause the rotating wheel 64 to rotate reversely, the rotating wheel 64 will drive the rotating disc 12 to rotate through the two rotating shafts 61, the belt 62 and the two bevel gears 65, so that the rotating disc 12 drives the profile to rotate to the next cutting machine 41 through the fixed cylinder 31; the inclined surface 321 of the sliding rod 32 will rotate to abut against the lower side of the pressing ring 16, and the pressing ring 16 will make the sliding rod 32 descend, so that the abutting plate 34 is pressed against the profile in the fixed cylinder 31, and the profile is kept stable.

The profile will rotate to abut against the guide surface 731 on one of the clamping plates 73 and cause the two clamping plates 73 to rise, the second spring 17 will deform, and the profile will push the workpiece below the pressing plate 72 to move; when the profile is turned to just below the press plate 72, the second spring 17 will return to its natural state and cause the two clamping plates 73 to descend, wherein the guide surface 731 on one clamping plate 73 will descend against the workpiece, and the clamping plate 73 will be inserted between the profile and the workpiece, so that the workpiece is pushed into the drop slot 14, and the workpiece will pass through the drop slot 14 and fall into the collecting box 15.

Then both the rack 63 and the gear are disengaged from the latch unit 641, the rotary table 12 will be stationary, the first spring 33 will urge the ball 18 to be latched in the latching groove 19, so that the rotary table 12 will be kept stable, and the mounting plate 4 will drive the cutter 41 to descend to cut the profile.

Then the hydraulic cylinder 52 will drive the mounting plate 4 to rise, so that the cutting machine 41 is detached from the profile, the gear wheel will correspond to one of the blank spaces 642, the rack 63 will engage with the gear wheel first and then engage with one of the latch units 641, so that the rotating wheel 64 rotates, the rotating wheel 64 will drive the rotating disc 12 to rotate through the two rotating shafts 61, the belt 62 and the two bevel gears 65, so that the rotating disc 12 drives the profile to rotate close to the next cutting machine 41 through the clamp 3.

Since the horizontal spacing between each group of cutters 41 and the center of the rotary table 12 is different, the section bars will be cut shorter and shorter along with the rotation of the rotary table 12 and the common cutting of the plurality of groups of cutters 41, and a plurality of section bars can be processed simultaneously. The automatic feeding, the self-holding of section bar are fixed, automatic rotation, automatic cutout and automatic unloading have been realized to this application to the machining efficiency of section bar has been improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
