[0020] like Figures 1 to 7As shown, a deformation-resistant thin-walled workpiece includes a workpiece main body matching structure 1 with a main body in the shape of a rectangular parallelepiped, a matching connection groove 2 penetrating the lower part of the whole body is provided at the upper end of the workpiece main body matching structure 1, a avoiding matching groove 3 opening to the right is provided on the right side of the matching connection groove 2, and a reinforcement matching groove completely penetrating the left side of the whole body in the up and down directions is provided on the left side of the matching connection groove 2, and different hardness materials can be replaced at this position. Since this position is a position that is easy to deform during use and processing, improving the structural hardness of this position can effectively ensure the overall anti-deformation situation. An anti-deformation reinforcement seat 4 is fused in the reinforcement matching groove, and the two materials are fused into a whole by heating and fusion. They can also be connected together by welding, but if welded, the strength of the connection position is not as high as the fusion strength. The material hardness of the anti-deformation reinforcement seat 4 is greater than the material hardness of the workpiece main body matching structure 1, ensuring that this position has reliable anti-deformation ability during later use. The upper end of the anti-deformation reinforcement seat 4 is provided with a main body installation matching groove 5 opening upward, and the lower end center position of the main body installation matching groove 5 is provided with a stress relief safety groove 6 opening upward and completely penetrating the end faces on both sides, which can produce better stress relief for the main structure during the overall heat treatment process during processing, so that the structure has better stability and higher strength. The lower end of the anti-deformation reinforcement seat 4 is provided with a matching limit groove 7 opening downward, which can assist in assembly during installation, so that the overall matching stability is better. The front side of the workpiece main body matching structure 1 is provided with an overall installation clamping groove 8 opening to the right and completely penetrating the overall front and rear directions. This position can be used for horizontal staggered matching connection during later use. It adopts a brand-new structural design. After cutting grooves on the main structure of the original workpiece, a supplementary structure made of a better hardness material is added to fuse them together into a whole. By adding stress relief grooves on this supplementary structure, internal stress can be effectively eliminated during heat treatment to ensure the strength of the overall structure. Since the supplementary structure is set at a position where the workpiece has a relatively large bearing capacity, the overall anti-deformation effect during use is better, and the overall production cost is lower, the safety during later use is better, and it is not easy to deform during the processing and later use.
[0021] Preferably, the outer end face of the anti-deformation reinforcement seat 4 coincides with the end face of the corresponding position on the outer side of the workpiece main body matching structure 1, ensuring better overall flatness of the outer side, better overall structural support strength, and longer service life during use.
[0022] Preferably, combined reinforcement columns are provided on both sides of the anti-deformation reinforcement seat 4 at the end faces where the workpiece main body matching structure 1 is in contact with the main body, and the combined reinforcement columns are integrated into the interior of the workpiece main body matching structure 1, so that the fusion connection strength between them is higher and the overall structural stability is better.
[0023] Preferably, the matching limiting groove 7 is a semi-cylindrical structure, which is more convenient during production and processing and has higher processing efficiency.
[0024] Preferably, the depth of the integral installation slot 8 in the left-right direction is greater than half of the thickness of the workpiece main body matching structure 1 in the left-right direction, to ensure that the combined matching space is larger and the matching stability is better during the subsequent matching use.
[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
