In this embodiment, the guiding mechanism mainly includes a hydraulic box 220 and two rows of contact fingers 230, a guiding channel extending along the front-back direction is provided on the hydraulic box 220, the two rows of contact fingers 230 are respectively assembled on the left and right side walls of the guiding channel along the left-right direction in a sealing and guiding manner, and the inner cavity of the hydraulic box 220 can push the two rows of contact fingers 230 to mutually support and cooperate. When the preheating component passes through the guide channel, the preheating component can push the two rows of contact fingers 230 to move to the left and right sides respectively, and the two rows of contact fingers 230 can be automatically locked after being far away from each other, so that the moving path of the preheating component in the guide channel can be accurately recorded.
Further, the hydraulic tank 220 is provided with a communication cavity 221 and a positioning cavity 222, the number of the positioning cavities 222 is the same as that of the contact fingers 230, and the contact fingers 230 are hermetically and guiding-assembled in the positioning cavities 222 in a one-to-one correspondence. A sensing valve 240 is further arranged between the positioning cavity 222 and the communicating cavity 221, and the sensing valve 240 can seal and separate the communicating cavity 221 from the positioning cavity 222, so that the position of the contact finger 230 in the positioning cavity 222 is locked, and a sensing piece 300 is adjacently arranged on the rear side of the preheating component.
The induction valve 240 comprises a moving block 250, a sealing plug 260 and a reset spring 270, wherein the sealing plug 260 can seal and separate the communication cavity 221 and the positioning cavity 222, the moving block 250 is fixedly connected with the sealing plug 260, and the induction piece 300 and the moving block 250 are made of magnetic materials, so that the induction piece 300 can attract or push the moving block 250 when approaching to the moving block 250, so as to drive the sealing plug 260 to move, and the separation of the communication cavity 221 and the positioning cavity 222 by the sealing plug 260 is relieved. When the sensing piece 300 gradually moves away from the moving block 250, the reset spring 270 can drive the sealing plug 260 to automatically reset so as to re-separate the communicating cavity 221 and the positioning cavity 222.
Specifically, when the distance between the sensing member 300 and the sensing valve 240 is smaller than the set value, the sensing valve 240 can be automatically opened to enable the communication cavity 221 to communicate with the positioning cavity 222, and the preheating component can push the contact finger 230 to move in the positioning cavity 222.

The foremost contact finger 230 of the guiding component is contacted with the foremost preheating head 320 of the preheating component, and the sensing piece 300 at the front side of the preheating component attracts the moving block 250 on the sensing valve 240 to drive the sealing plug 260 to move, so that the sensing valve 240 is opened, and the communicating cavity 221 is communicated with the positioning cavity 222 corresponding to the contact finger 230.
At this time, the contact fingers 230 are moved to the left and right sides, respectively, by the pressing of the preheating head 320, so as to adapt to the position and width of the preheating head 320. As the sliding seat 110 continues to move forward, the sensing piece 300 gradually moves away from the sensing valve 240 corresponding to the contact finger 230, and under the action of the return spring 270, the moving block 250 drives the sealing plug 260 to automatically reset, and the sensing valve 240 automatically closes to re-separate the communication cavity 221 from the positioning cavity 222, so that the position of the contact finger 230 is locked, and the position of the preheating head 320 is accurately recorded between the contact fingers 230. As the preheating head 320 is continuously moved forward in the guide path, the two rows of contact fingers 230 are pressed and shaped, thereby accurately and rapidly reproducing the moving path of the preheating head 320.
Because the widths of the welding component 330 and the heat treatment component are the same as those of the preheating component, the moving path recorded and formed between the two rows of contact fingers 230 can accurately guide the subsequent welding component 330 and the heat treatment component so as to accurately preheat, weld and post-weld heat treat the gaps to be welded on the die.
The device adopts a mechanical structure, realizes the memory repetition of the operation process, effectively improves the continuity of preheating, welding and post-welding heat treatment operation, simplifies the laser welding operation flow of irregular welding seams, greatly improves the welding efficiency and the welding seam quality, and reduces the labor intensity of operators. Compared with electronic induction control welding, the welding device has the advantages that the structure is simple, the upper limit of accuracy is high, and the positions of preheating, welding and postweld heat treatment can be completely consistent, so that the welding strength is guaranteed.
