The cooperation of the table and the fixing component greatly improves the convenience of replacing the straightening device, and is also convenient for the subsequent installation of the rounding device, thereby realizing the dual-purpose function of the profiling machine, making the profiling machine more applicable; when the profiling machine is used to straighten the vertical pipe, the vertical pipe is manually placed on the table 16 and placed below the expansion mold, and the expansion mold 6 is driven down by the cylinder 2 and the upper workbench 3 to perform expansion straightening on the vertical pipe on the lower side of the expansion mold 6; the profiling machine is designed and manufactured according to production needs, with a small overall volume and a large cylinder stroke, suitable for punching and shrinking of workpieces of various sizes, and convenient for loading and unloading workpieces. Compared with the traditional hydraulic presses with large table tops, small strokes, and workpieces that cannot be placed in the center of the cylinder, working under eccentric loads, and serious damage to the cylinder, this machine is easy and flexible to operate, can be operated by one person, improves production capacity, and saves labor.

[0055] In a specific embodiment, reinforcing ribs 11 are provided on both sides of the movable clamping plate 91 and the fixed plate 101 to ensure connection strength and enhance structural stability.
