Abstract

The invention discloses a drawing die for left and right front longitudinal beam outer plates. The drawing die for the left and right front longitudinal beam outer plates comprises an upper die base,an upper die knife, a blank holder, a male die base and a low die base. The upper die knife is arranged on the upper die base, the male die base is evenly arranged on the lower die base, and the blankholder is arranged on the male die base and supported by the lower die base; a molding groove, a first process lug boss, a second process lug boss and two third process lug bosses are arranged in theupper die knife, a first molding part, a second molding part and a fourth process lug boss are arranged in the molding groove, the fourth process lug boss is located at the second end of the moldinggroove, a fifth process lug boss is arranged between the first molding part and the inner side of the second molding part, sixth process lug bosses are arranged on the outer sides of the first moldingpart and the second molding part, and two corners of the first end of the male die base are provided with adjustment planes. The drawing die for the left and right front longitudinal beam outer plates has high qualified rate of produced products and can produce the left and right front longitudinal beam outer plates at one time.

Description

technical field [0001] The invention relates to the technical field of manufacturing left and right front longitudinal beam outer panels, in particular to a drawing die for left and right front longitudinal beam outer panels. Background technique [0002] For drawing such a large flat piece with a very large arc, and it is B280 / 440DP material, the resilience is extremely large, it is not easy to become rigid deformation, and it is easy to have wrinkles during the drawing process, which will easily lead to defects. good and bad. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a drawing die for the left and right front longitudinal beam outer plates capable of forming rigid deformation for large flat parts. [0004] In order to solve the above problems, the present invention provides a drawing die for the left and right front side beam outer panels. The left and right front side beam outer panel drawing dies inclu...
