Description

Technical Field

[0001] This utility model relates to the field of frame corner technology, and in particular to a frame corner welding structure. Background Technology

[0002] The frame corner welding structure is a structural form that firmly connects the various components of a frame at the corners. It is widely used in many fields such as construction, machinery manufacturing, and automotive industry. It uses welding processes such as manual arc welding and gas shielded welding, and flexibly applies welding methods such as butt joints, corner joints, and T-joints according to actual needs to tightly fuse the metal materials at the corners of the frame.

[0003] However, in the existing technology, under the dual influence of the physical characteristics of the welding process and the complexity of the frame structure, the weld metal and the base material have different coefficients of thermal expansion during the local high-temperature melting and cooling solidification process of welding. The cooling and contraction pace is inconsistent, and stress accumulation points are naturally formed at the corners. Especially when facing the corners of complex-shaped frames, heat transfer is hindered and the distribution is unbalanced. The cooling time difference of each part is large, and the internal stress accumulates in a disordered manner, causing the welded parts to deform and crack, reducing the structural load-bearing capacity and service life. Utility Model Content

[0004] The purpose of this invention is to address the problem in the existing technology where, under the dual influence of the physical characteristics of the welding process and the complexity of the frame structure, the weld metal and the base material have different coefficients of thermal expansion during the local high-temperature melting and solidification process, resulting in inconsistent cooling and contraction paces. This leads to the natural formation of stress concentration points at the corners, especially when facing the corners of complex-shaped frames. Heat transfer is hindered, distribution is unbalanced, cooling time differences are large in different parts, and internal stress accumulates disorderly, causing the welded parts to deform and crack, reducing the structural load-bearing capacity and service life. Therefore, this invention proposes a frame corner welding structure.

The four corners of the frame body are reinforced by the reinforcing frame, and the first and second reinforcing rods inside the reinforcing frame are used to reinforce the reinforcing frame. This allows the reinforcing frame to stably reinforce the four corners of the frame body, thereby improving the strength and stability of the four corners of the frame body and preventing excessive stress on the frame body during the welding process, which would lead to poor stability of the corners of the frame body.
