Simple and practical bending machine

The utility model relates to the technical field of bending machines, in particular to a simple and practical bending machine which comprises a loading frame, a bending hydraulic assembly is arranged in the middle of the lower base face in the loading frame, and blocking assemblies are arranged on the upper side in the loading frame in a bilateral symmetry mode. An angle positioning assembly is arranged in the middle of the upper side of the interior of the loading frame, a bent object is placed at the end of a bending hydraulic assembly, a bending base and a mounting base are detachably connected, the bending base can be replaced according to the bent object, the overall applicability is high, the bent object can be positioned through an object stopping base, and the bending efficiency is improved. The bending positioning stability of a bent object is high, the bending angle of the bent object can be positioned and set in advance through the angle instrument, the first angle indicating arm and the second ang
