Background

The hinge for the door of the vehicle comprises a U-shaped plate 1, and two sides of an opening part of the U-shaped plate 1 are provided with pin lugs 2 which extend outwards, as shown in figure 1. The automobile door hinge is generally manufactured by bending a plate, forming a door hinge blank, and cutting two flanged edges of the door hinge blank to obtain a pin lug. Because the surface of the closed end of the U-shaped plate is arranged obliquely, the pin lug part of the door hinge is inclined when the material is removed.

At present, the inclined plane of the car door hinge is processed by adopting a standard inclined wedge of a universal stamping die in the industry. However, the standard tapered wedge has a large size, and a large-sized stamping die needs to be arranged, so that the overall size of the whole die is large. Moreover, the standard tapered wedge has a large size, and interferes with other parts in the stamping die, so that the working efficiency is reduced. In addition, a large stamping die needs to be matched with a high-power punch press, and the production cost is high.
