The reinforcing ribs 38 can reduce the instability of the support frame 15 during the force and deformation process, reduce the influence of stress concentration on the support frame 15, and improve the stability of the connection between the support frame 15 and the base 14. The support frame 15 is provided with a positioning assembly for positioning the cross plate 1, and the positioning assembly includes a first positioning column 16 which is bolted to the support frame 15 and matches the size of the first mounting hole 2 of the cross plate 1. The end of the first positioning column 16 which is away from the support frame 15 is provided with a chamfer for facilitating the installation of the cross plate 1.

The first fixing assembly 17 also includes a first clamping cylinder 21 arranged on the base 14. In the embodiment of the present application, the number of the first clamping cylinders 21 is set to two, and the two first clamping cylinders 21 are respectively located on both sides of the first bottom block 6. The output ends of the two first clamping cylinders 21 are both provided with a first pressing plate 22, and the first bottom block 6 is pressed tightly between the first pressing plate 22 and the first support block 19.
[0036] Therefore, the first support block 19 supports the first bottom block 6, and the second positioning column 20 limits the position of the first bottom block 6, thereby fixing the position of the first bottom block 6 on the first support block 19, making it easier for operators to perform welding operations, and improving weld quality and production efficiency.

[0039] Reference Figure 2 The base 14 is bolted with an auxiliary stopper 37, and the surface of the auxiliary stopper 37 facing the second bent plate 4 contacts the end surface of the connecting column 5 away from the second bent plate 4. The auxiliary stopper 37 supports the connecting column 5, improves the stability of the second bent plate 4 during welding, and improves the weld quality and production efficiency.
[0040] Reference Figure 2 The third fixing assembly 39 includes a side support frame 27 disposed on the base 14.

Therefore, the operator can connect the connecting frame 8 to the side support frame 27 by bolt connection, and connect the bending block 9 to the side support frame 27 by bolt connection, and then use welding equipment to perform welding operations. After welding is completed, the connecting frame 8 and the bending block 9 are separated from the side support frame 27 by bolt disassembly.
