Abstract
The invention discloses a stamping die used for conducting bending. The stamping die comprises an upper die and a lower die. An insert core is embedded in the lower die. A positioning pin used for positioning a panel is arranged on the upper surface of the insert core. An elastic pressing block used for pressing the panel is arranged on the portion, above the insert core, of the upper die. A first inclined wall is arranged on one side of the insert core. The upper end of the first inclined wall and one side of the elastic pressing block are aligned in the vertical direction. The portion, on one side of the elastic pressing block, of the upper die is provided with a punch pin used for bending the panel. One side of the punch pin is provided with a second inclined wall. The lower end of the second inclined wall is in clearance fit with one side of the elastic pressing block. The second inclined wall and the first inclined wall are parallel to each other. Due to the first inclined wall, the bent edge conveniently bearing force is formed on the top of the insert core, and meanwhile enough bending space is reserved for a bent piece. Due to the second inclined wall, bending resistance between the punch pin and the panel is reduced. The stamping die is simple in structure, stable and reliable in bending, and capable of effectively reducing bending resistance.
