Description

Technical Field

[0001] The invention relates to refined steel weld bead milling and surface grinding equipment, belonging to the technical field of refined steel processing equipment. Background Art

[0002] After welding a rectangular-section refined steel workpiece (hereafter referred to as refined steel), the weld beads (four in total, referred to as "excess weld beads") that extend above the surface must be removed. The traditional method for removing these excess weld beads is manual belt grinding. However, this traditional method can only grind each excess weld bead individually, which is inefficient. Furthermore, this manual grinding method leaves the refined steel surface uneven, requiring the application of filler material (commonly known as putty) to smooth the surface before spraying or painting, a cumbersome process. Furthermore, because the sprayed or painted paint adheres to the filler material, refined steel produced in this manner can crack after prolonged use. Therefore, to address these issues, a device for milling and surface grinding refined steel weld beads is urgently needed. Summary of the Invention
