(2) cutting and opening holes: according to the shape of the diagonal rod 21 to be formed on the cylindrical surface of the profile 3 (i.e. according to the design requirement), the redundant connecting parts between the four columns 20 of the profile 3 and the diagonal rod 21 are cut off, so that the diagonal rod 21 and the four columns 20 of the profile 3 are connected through the connecting ribs 22, as shown in fig. 1.
It should be noted that: the connecting ribs 22 are the remaining parts of the profile 3 after cutting off the redundant connecting parts between the four columns 20 and the inclined rods 21. The resulting monolithic lattice column is shown with reference to fig. 2. The shape of the diagonal rods 21 on the cylindrical surface of the profile is not limited to the one shown in fig. 2, but other shapes can be designed.

It should be understood that: because the width of two surfaces of the section bar 3 is larger than that of the other two surfaces after the section bar 3 is stretched, in order to fix the section bar 3 after the section bar 3 is overturned, the clamping movable mechanism and the clamping fixing mechanism also ascend to the height matched with the section bar 3, so that the clamping movable mechanism and the clamping fixing mechanism fix the section bar 3, namely the clamping movable mechanism and the clamping fixing mechanism are set to be telescopic mechanisms.

The height of the base 1 can be adjusted through the arranged hydraulic jack 2, so that the height position between the base 1 and the clamping fixing mechanism and the clamping moving mechanism is adjusted, and the base 1 can be suitable for sectional materials with different cross sections.
The clamping fixing mechanism and the clamping movable mechanism are arranged on two sides of the base 1 in a separated mode along the length direction of the base 1. The driving mechanism is arranged on one side of the clamping movable mechanism and is parallel to the clamping movable mechanism, and the sliding rails 4 are arranged between the clamping movable mechanism and the driving mechanism and are parallel to each other.

Of course, only when the sleeve 24 completely extends out of the first strip-shaped groove, at this time, although the sleeve 24 cannot increase the stability between the first fixing plate 7 and the first telescopic plate 8, because the output rod portion of the first cylinder 9 is located in the sleeve 24, the stability of the cylinder output rod in the second strip-shaped groove can also be increased, and the first telescopic plate 8 or the cylinder output rod is easily damaged or broken if the first telescopic plate 8 is inclined.

If the blocking sheet does not play a limiting role in an extreme case, only the sixth air cylinder 32 needs to be driven to extend continuously until the lower gripper 31 abuts against the upper gripper 26.
It should be noted that: the curvature of the upper gripper 26 is greater than that of the lower gripper 31, and as can be seen from fig. 5, the upper gripper 26 extends from the top and bottom of the profile 3 (the gap between the pillar 20 and the connecting rib 22), respectively, and extends from the gap between the pillar 20 and the connecting rib 22 on the side close to the first fixing plate 7 and the first expansion plate 8, which is equivalent to the upper gripper 26 being able to completely catch the pillar 20 of the profile 3, and at this time, the tip portion of the lower gripper 31 is inserted into the gap of the tip portion of the upper gripper 26, so that the lower gripper 31 abuts against the upper gripper 26, thereby completing the fixing of the pillar 20 of the profile 3.

Because second expansion plate 12 can go up and down on second fixed plate 11, consequently, need can dismantle fixedly with second expansion plate 12 fixed connection's third cylinder 15 and third fixed plate 14, specifically be: a plurality of through holes which are arranged in order are arranged on the plate surface of the third fixing plate 14 and in the area corresponding to the second expansion plate 12, a backing plate 33 is fixed on a cylinder seat of the third cylinder 15 connected with the second expansion plate 12, a threaded hole is arranged on the backing plate 33, when the second expansion plate 12 rises upwards, the third cylinder 15 moves upwards along with the backing plate, and is fixed on the third fixing plate 14 through a bolt, so that the purpose that the third cylinder 15 moves along with the second expansion plate 12 is achieved.
Further, during the process of fixing and stretching the columns 20 of the section bar 3 directly by means of the electric manipulator, there may be some indentations caused by the electric manipulator to the columns 20, thus affecting the appearance of the monolithic lattice column. Therefore, the detachable supporting mechanisms are vertically and symmetrically arranged on the inner wall of the section bar 3, namely before the electric manipulator fixes the column 20, the supporting mechanisms are put into the inner pipe of the section bar 3 and are attached to the inner walls of the left side and the right side inside the section bar 3, so that the electric manipulator fixes the supporting mechanisms to fix the column 20.
The supporting mechanism comprises symmetrically arranged supporting strips 16 with right trapezoid cross sections, the two supporting strips 16 are respectively attached to the inner walls of the columns 20 of the section bar 3, the two supporting strips 16 are fixedly connected through supporting plates 17, the supporting plates 17 are divided into first supporting plates and second supporting plates, fifth strip-shaped grooves are respectively formed in the corresponding surfaces of the first supporting plates and the second supporting plates, and the first supporting plates and the second supporting plates are fixed through a plurality of fourth cylinders 18 fixed in the fifth strip-shaped grooves; the support bars 16 are respectively provided with arc-shaped holes 19 for the first electric manipulator and the second electric manipulator to pass through. It should be understood that: the two ends of the supporting plate 17 are fixed on the upper bottom surfaces (small diameter surfaces) of the two supporting bars 16 respectively, and the lower bottom surfaces (large diameter surfaces) of the supporting bars 16 are attached to the inner wall of the section bar 3. In order to realize that the electric manipulator penetrates through the support bar 16 to grab and fix the column 20, the width of the lower bottom surface of the support bar 16 is larger than 4/5 of the distance between the column 20 and the connecting rib 22 on the upper surface of the section bar 3, so that the arc-shaped holes 19 are completely arranged in the gap between the connecting rib 22 and the column 20, the upper mechanical claw 26 can smoothly penetrate through the arc-shaped holes 19 to grab and fix the support bar 16, the column 20 is fixed, and the problem of indentation caused by the fact that the electric manipulator stretches and fixes the column 20 is solved.
Further, after two side surfaces of the profile 3 are stretched and formed, when the other two side surfaces are stretched, the profile 3 needs to be turned over by 90 degrees, and for the turning mechanism disclosed by the invention, the profile 3 can be manually turned over after being hoisted by using an existing crane. The presently disclosed canting mechanism can also be used. It should be noted that: the turnover mechanism can be used only when the two side faces of the section bar 3 need to be stretched and the other two sides need to be stretched, and when the turnover mechanism is not needed, the turnover mechanism is separated from the section bar 3 and is placed on one side.
The turnover mechanism comprises a rotary column 34 which is longer than the section bar 3 and penetrates through the section bar 3, two ends of the rotary column 34 extend out of the section bar 3 and are arranged on upright columns 35 through bearings, electric jacks 36 are fixed on the bottom surfaces of the two upright columns 35, and a plate trailer can be placed at the bottoms of the electric jacks 36, so that the electric jacks 36 and the rotary column 34 can be pushed to move conveniently.

In use, the electric manipulator needs to be separated from the column 20. It should be noted that: the rotary column 34 provided with the gear 37 at one end is fixed with the upright column 35 through a bearing, the other end of the rotary column 34 is fixed on the upright column 35 through a separation from the inner ring of the bearing (namely, the rotary column 34 extends into the inner ring of the bearing to separate from the inner ring, and the outer ring of the bearing is fixed on the upright column 35), and the mode that one end of the rotary column 34 is fixed with the upright column 35 is not fixed is suitable for the condition that the length of the section bar 3 is less than 6 m. It should be noted that: if the length of the section bar 3 is too long and is larger than 6m, the rotating column 34 cannot completely and conveniently extend into the section bar 3, therefore, the rotating column 34 can be arranged into two sections, each section is fixed with the upright post 35 through a bearing, the two sections of the rotating columns 34 respectively extend into the section bar 3 from two ends of the section bar 3, and in the section bar 3, the two sections of the rotating columns 34 are butted in a concave-convex matching mode, so that the installation of the turnover mechanism in the section bar 3 is completed.
