[0038] Referring to Figure 2 and Figure 3The fixing device 21 comprises the fixing pin 16 and the fixing side plate 13, wherein the fixing side plate 13 comprises the seat body 131 and the plate body 132, the rear part of the seat body 131 is protruded relative to the plate body 132, the seat body 131 is provided with a plurality of threaded holes two 18, the number of the threaded holes two 18 is four, and the four threaded holes two 18 are distributed in a quadrangle; the triangular frame plate 1 is provided with the mounting part 14, which is located at the side of the triangular frame plate 1 close to the pressing device 5, the mounting part 14 is provided with a plurality of threaded holes one 17, the number of the threaded holes one 17 is equal to that of the threaded holes two 18, each threaded hole one 17 is connected with the connecting piece 20, and the connecting piece 20 is preferably a bolt; the triangular frame plate 1 is provided with the mounting groove 23, which is arranged at the outer side of the mounting part 14 and is used for embedding the rear part of the seat body 131, at this time, the four threaded holes one 17 and the four threaded holes two 18 are in one-to-one correspondence and in communication, the connecting piece 20 is in one-to-one correspondence and passes through the threaded hole two 18 and is connected in the corresponding threaded hole one 17, so as to connect the seat body 131 and the mounting part 14 and further fix the fixing side plate 13 and the triangular frame plate 1.

[0039] The plate body 132 is in a plate shape and has a relatively thin thickness, so that the plate body 132 can pass through the gap between the steel one 100 and the steel two 200, the plate body 132 is provided with the mounting hole 15, which is in a rectangular shape and is arranged at the lower part of the plate body 132, the mounting hole 15 is inserted with the fixing pin 16, the span distance between the upper end face of the fixing pin 16 and the lower end face of the triangular frame plate 1 is adapted to the thickness of the upper part of the steel one 100, so as to form a clamping effect on the steel one 100 and position the triangular frame plate 1 on the steel one 100, the fixing pin 16 is further provided with the limiting part 19 at the end close to the steel two 200 along the insertion direction, when the pressing device 5 drives the steel one 100 and the steel two 200 to approach, the steel one 100 abuts against one end of the fixing pin 16, the steel two 200 can move to approach and abut against the other end of the fixing pin 16, at this time, the positions of the steel one 100 and the steel two 200 are in alignment and folded, so as to improve the alignment accuracy and efficiency.

The output end can be a piston rod arranged on the top pressing device 5 and can be extended or retracted. The output end of the top pressing device 5 abuts against the lower end surface of the top pressing part 2. The top pressing device 5 drives the output end to extend to apply a pushing force to the top pressing part 2. Based on the interaction of forces, the top pressing device 5 and the tripod plate 1 have a tendency to move relative to each other. The top pressing device 5 applies a downward pressure to the steel material two 200. The tripod plate 1 pulls the steel material one 100 through the fixed pin 16, causing the steel material two 200 to move closer to the steel material one 100 and tend to be flat until the steel material two 200 abuts against the fixed pin 16 and cannot move.

The leveling driving part 51 drives the output end to lift upward to continuously press the top pressing part 2 of the tripod plate 1, forming a lever effect. The tripod plate 1 is displaced under the action of the fulcrum of the fixed pin 16. At the same time, the reaction force of the top pressing device 5 pushes the steel material two 200 to move in the direction of the steel material one 100, so that the two steels are precisely leveled during the folding and positioning process. The two steels are quickly aligned under the bidirectional cooperative motion, improving the efficiency of the folding operation.
