As a matter of fact, the edged corners are positioned by a guide pin (not shown) on the base side via the compression spring 30, and the movable amount is the mold 31 and its side. The stationary receiver placed in the section includes a stand 32, a stationary press die 33 attached to the machine frame that moves up and down above these, and a guide bin (not shown) positioned on the side of the die 33, which is deflected by a compression spring 34. It is possible to use a machine equipped with a movably mounted processing cut-off mold 35. In this mechanism, the movable amount is the same as the rising dimension of the bending part 12, or a position slightly larger than the rising dimension of the bent part 12, between the plate surface on which the metal material 10 is placed on the mold 31 and the plate surface of the base 32. is supported by a compression spring 30. In addition, the amount of movement is such that the mold 31 and the movable cut-off mold 35 are arranged so that as the movable cut-off mold 35 moves downward together with the fixed push mold 33, a gap wider than the thickness of the metal material 10 is provided between the opposing surfaces. It is set up. In this processing die, as shown in FIG. The movable amount is determined by assembling the metal material 10 so that it is positioned on the side surface of the mold 31, and then moving the fixed pressing mold 33 and the movable blocking mold 35 downward to press the metal material 10, as shown in FIG. In this case, the mold 31 is deflected downward. Along with this, the bending part 12, which had the same thickness a as the metal material 10, has a movable amount of 31 degrees and a fixed support of 32 degrees. Fixed push mold 33. Possible]
By being compressed within the space formed by the blocking mold 35, the metal material moves to the empty part of the space and is formed as a bent part 12a having a relatively thick wall, and
By pushing up the bent portion 12a, the corner portion 13a is formed to have a sharp edge smaller than the original curvature. This edging process was carried out by pushing up from the tip side of the bent part 12, but it can also be done by pushing up from the end face side of the bent part 12 instead.
