Embodiment 1

[0028] This embodiment provides a method for manufacturing the drawing die surface at the handle of the outer panel of an automobile door, see figure 1 , The manufacturing method includes:

[0029] When making the drawing die surface at the handle of the car door outer panel, the boundary of the door outer panel handle area A surface 1 is extended along its own curvature to form a boundary extension 11, the length of the boundary extension 11 is preferably 0.5 mm ~2.0mm, more preferably 1mm; the boundary extension section 11 intersects the straight section 2 that forms an angle of 10° with the A surface 1. The straight section 2 continues to extend to form a drawn wall 4, which is 25 with the punching direction °Included angle; the drawn wall 4 intersects the blanking surface 5 after extension. As another embodiment, the boundary extension section 11 can be selected to intersect the straight line section 2 with any included angle in the range of 8°~15° with the A surface 1 as re...

Embodiment 2

[0035] This embodiment provides an outer panel of an automobile door, which has a drawing die surface at the handle manufactured by the method of the first embodiment.

[0036] The sequence numbers of the foregoing embodiments of the present invention are only for description, and do not represent the superiority of the embodiments.

Abstract

The invention discloses a manufacturing method of a drawing die face on a handle of an outboard door panel of an automobile. The manufacturing method comprises the following steps that: when the drawing die face on the handle of the outboard door panel of the automobile is manufactured, a border of an A face (1) of an area of the handle of the outboard door panel is extended along self curvature to form a border extending section (11); the border extending section (11) is intersected with a straight-line section (2) which forms an included angle of 8 degrees-15 degrees with the A face (1); the straight-line section (2) is continuously extended to form a drawing wall (4); the drawing wall (4) and a punching direction form an included angle of 20 degrees-25 degrees; and the drawing wall (4) is extended to be intersected with a binder face (5). The drawing die face belongs to the field of components of the outboard door panel of the automobile. The invention also disclosed the outboard door panel of the automobile. The phenomenon that the A face on the handle of the outboard door panel is easy to deform is effectively improved, the plasticity deformation rate of the outboard door panel is improved, and the rigidity is improved.

Description

Technical field [0001] The invention relates to the field of automobile body components, in particular to a method for manufacturing a drawing die surface at a handle of an outer panel of an automobile door. The invention also relates to an automobile door outer panel manufactured by the above method. Background technique [0002] With the continuous development and progress of the automobile industry, the requirements for the appearance quality and material utilization of automobile outer coverings are getting higher and higher, which requires designers to continuously improve the design and manufacturing process level. In the process of passenger car development, door covers, as the surface carrier of the entire vehicle system, bear increasing aesthetic and engineering pressure. On the one hand, as a consumer, the vehicle is required to have a beautiful appearance and unique shape. On the other hand, engineering technology restricts the unique shape of the vehicle. The ideal c...
