As another embodiment, plane can will be bent out between two bottom plates 150, plank is bent into hexagon.
Further, the width of the first side plate 110 that bending goes out is equal to the width of the second side plate 120, so that formed five
The both sides uniform force of side shape arm support, the width of the first top plate 130 that bending goes out is equal to the width of the second top plate 140, by first
After the welding of 130 and second top plate 140 of top plate, weld seam 200 is located at the middle part of top plate width direction, the first top of 200 both sides of weld seam
130 and second top plate of plate, 140 stress equalization improves the bonding strength of weld seam 200.
Further, process optimization is carried out to the plank after bending, to reduce the opening of the plank after bending, be convenient for
Next process.
For bending tool 400 is made to be moved out out of pentagon arm support, the plank after bending is in the first top plate 130 and the second top plate
There are opening between 140, meanwhile, under the action of plank elastic restoring force, the first top plate 130 and the second top plate 140 have to
The trend of direction movement being located remotely from each other, carries out process optimization to the plank after bending, reduces the first top plate 130 and the second top plate
The distance between 140, convenient for being welded to the first top plate 130 and the second top plate 140.
Further, pressurize is carried out to the plank after bending by device for exerting, to reduce the opening of the plank after bending.
Specifically, setting pressure to the first side plate 110 and the second side plate 120 respectively, make the first side plate 110 and the second side plate 120
It is moved to direction close to each other, so as to which the first side plate 110 be made to drive the first top plate 130 to close to the direction of the second top plate 140
Movement, the second side plate 120 drives the second top plate 140 to be moved to the direction close to the first top plate 130, so as to reduce the first top plate
130 and second the distance between the top plate 140, convenient for connecting the first top plate 130 and the second top plate subsequently through the mode of welding
140。
Further, pressurize is carried out to the plank after bending using hydraulic cylinder 500.
As shown in figure 5, the cylinder body 510 of hydraulic cylinder 500 is fixedly connected in supporting block 530, the piston rod of hydraulic cylinder 500
Pressure block 540 is rotatably connected to by shaft 550 on 520, the right side of hydraulic cylinder 500 is equipped with stopper 560, pressure block 540 with
Bearing 570 is equipped between stopper 560；When carrying out pressurize to the plank after bending, the plank after bending is placed in bearing 570
On, top plate is located at the top of the first side plate 110 and the second side plate 120, and the first side plate 110 is contacted with the side of stopper 560, applied
The side of briquetting 540 is contacted with the second side plate 120, alternatively, the second side plate 120 is contacted with the side of stopper 560, press block
540 contact with the first side plate 110, since there are opening, the first side plates 110 and between the first top plate 130 and the second top plate 140
Two side plates 120 are not parallel, and the side for the block 540 that presses is in pressure top rake；In course of exerting pressure, the first top plate 130 and the second top plate
140 is close to each other, and the first side plate 110 and the second side plate 120 are gradually parallel, pressure block 540 around the shaft 550 axis rotation, protect
The contact with the first side plate 110 or the second side plate 120 is held, preferably to carry out pressurize to the plank after bending.After bending
Plank carries out pressurize operation, reduces the opening between the first top plate 130 and the second top plate 140, facilitates welding 130 He of the first top plate
Second top plate 140.
As another embodiment, working plate 600 is arranged in the plank after bending, to reduce the plank after bending
Opening.
As shown in fig. 6, working plate 600 is equipped with U-type groove, the width of U-type groove is due to the lateral surface of the first side plate 110 and the
Working plate 600 is arranged on the plank after bending by the distance between lateral surface of two side plates 120, reduce the first top plate 130 with
