[0002] During the processing of high-strength steel plate welded structural parts, welding equipment is needed to weld two groups of high-strength steel plates. During the welding process, when the weld metal cools, the solubility of hydrogen in the metal drops sharply, and hydrogen atoms diffuse and gather in the stress concentration area, combining into hydrogen molecules, generating great pressure, leading to cold cracks. At the same time, high-strength steel plates have a greater tendency to harden, and martensitic structure is easily formed in the welding heat-affected zone. Martensite has high hardness and poor plasticity, and is easy to crack under the action of restraint stress, reducing the service strength of the steel plate after welding.

After the movement is completed, the welding action of the welding head 107 and the sliding action of the movable slide rail 103 are used to perform welding operations on the position between the two groups of high-strength steel plate bodies 108. Among them, the movable slide rail 103, the lifting slide rail 105 and the welding head 107 are conventional moving parts and welding parts on the welding equipment. They are used as the prior art in this application and will not be described in detail here.

The hammering action can cause the weld metal to undergo plastic deformation. This plastic deformation can refine the grains of the weld metal and generate compressive stress inside the weld, reducing the possibility of cold cracks.

In the process of abutting, the spherical hammer head 304 is rotated inside the hemispherical grooves 1002 through the rotation of the rotating assembly, and the outer surface of the spherical hammer head 304 is cleaned through the friction generated during the rotation process, so as to avoid the spherical hammer head 304 from sticking to the welding liquid and solidifying after hammering the weld, resulting in sharp corners on the outside of the spherical hammer head 304, which further facilitates subsequent high-quality hammering operations.

During the rotation of the cam 503, the intermittent squeezing effect of the cam 503 and the strip plate 501 and the reset effect of the connecting component on the strip plate 501 and the lifting plate 302 after being stressed are used, so that the lifting plate 302 and the strip plate 501 are subjected to force and perform reciprocating lifting and lowering motion inside the installation frame 301.

[0028] In this scheme: A high-strength steel plate welding structure welding equipment comprises the following steps: During the welding operation of the high-strength steel plate welded structural parts using the welding equipment, two groups of high-strength steel plate bodies 108 are placed at designated positions on the workbench 101. After the placement is completed, the front end of the welding head 107 is located at the position to be welded between the two groups of high-strength steel plate bodies 108 through the driving action of the movable slide rail 103 and the lifting slide rail 105. After the movement is completed, the welding operation is performed on the position between the two groups of high-strength steel plate bodies 108 through the welding action of the welding head 107 and the sliding action of the movable slide rail 103; During the welding process, the lifting plate 302 is driven to perform reciprocating lifting and lowering motions inside the installation frame 301 through the cooperation between the extrusion assembly and the connection assembly. During the reciprocating lifting and lowering motions of the lifting plate 302, the spherical hammer head 304 is driven to perform reciprocating motions up and down inside the installation frame 301 through the connection between the spline sleeve 303 and the first telescopic assembly. During the downward motion of the spherical hammer head 304, the lower end of the spherical hammer head 304 is finally abutted against the weld seam produced after welding between the two sets of high-strength steel plate bodies 108, thereby hammering the weld metal (see FIG. Fig.10 ), the weld metal can be plastically deformed by hammering, and this plastic deformation can refine the grains of the weld metal and generate compressive stress inside the weld. The compressive stress can offset part of the tensile stress caused by hydrogen diffusion and solidification shrinkage, thereby reducing the possibility of cold cracks. In the process of reciprocating lifting of the lifting plate 302, the rack 702 is driven to rise and fall synchronously through the connection of the elastic component. In the process of the lifting and falling movement of the rack 702, the one end of the fixed pin 801 is sequentially pushed against the third inclined surface 803 on each group of push plates 802 and the elastic component resets the rack 702 after being stressed, so that the rack 702 reciprocates in the horizontal direction while lifting and falling. The rack 702 reciprocates in the horizontal direction. During the movement, the spline sleeve 303 is driven to reciprocate through the mutual meshing transmission between the rack 702 and the gear 701. During the reciprocating rotation of the spline sleeve 303, the spherical hammer head 304 is driven to reciprocate synchronously through the connection effect of the first telescopic component. When the weld produced by the spherical hammer head 304 and the two sets of high-strength steel plate bodies 108 are against each other, the rotation of the spherical hammer head 304 causes the hammering force to generate a tangential stress component on the weld surface. This tangential stress can also cause the weld metal to be compressed and kneaded to a certain extent in the horizontal direction, which can better make the weld and the base material more closely bonded, and further avoid the occurrence of interlayer tearing and other situations that may cause cold cracks; In the process of hammering the weld by the spherical hammer 304, as the spherical hammer 304 descends, the spherical hammer 304 first abuts against the hemispherical grooves 1002 on the two sets of processing plates 1001. During the abutting process, the spherical hammer 304 rotates inside the hemispherical grooves 1002 through the rotation of the rotating assembly (see FIG. Fig. 9), the outer surface of the spherical hammer head 304 is cleaned through the friction generated during the rotation process, so as to prevent the spherical hammer head 304 from sticking to the welding liquid and solidifying after hammering the weld, resulting in sharp corners on the outer side of the spherical hammer head 304, further facilitating the subsequent high-quality hammering operation. In the process of the spherical hammer head 304 abutting against the inner wall of the hemispherical groove 1002 and rotating, as the lifting plate 302 continues to move downward, the lower ends of the two groups of transmission rods 1203 are respectively abutted against the second inclined surfaces 1202 on the two groups of transmission plates 1201, pushing the two groups of processing plates 1001 to move away from each other under force. Through the mutual away and contraction movement of the two groups of processing plates 1001, the spherical hammer head 304 can be normally descended to perform the hammering operation on the weld (see Fig.10 ), and in the process of the spherical hammer head 304 rising and resetting after hammering the weld, as the spherical hammer head 304 rises and resets, the spherical hammer head 304 abuts against the two groups of first inclined surfaces 1003 at the lower ends of the two groups of processing plates 1001, and the two groups of processing plates 1001 are driven again to move away from each other under force, which further facilitates the normal resetting operation of the spherical hammer head 304.
