Inner longitudinal beam A section curved surface stamping die

The invention discloses an inner longitudinal beam A section curved surface stamping die. The forming surfaces of the inner longitudinal beam A section curved surface stamping die are stretching curved surfaces, and symmetrical limiting nails are correspondingly arranged on a lower die forming block. When a left inner longitudinal beam and a right inner longitudinal beam are machined, limiting holes in a front working procedure piece of the left inner longitudinal beam correspond to the first limiting nail, the second limiting nail, the third limiting nail and the fifth limiting nail respectively. Limiting holes in a front working procedure piece of the right inner longitudinal beam correspond to the first limiting nail, the second limiting nail, the fourth limiting nail and the sixth limiting nail respectively. Therefore, the die can be used for stamping the forming surfaces of the left and right inner longitudinal beams, the application range of the die is widened, and the manufacturing cost is reduced. 本发明
