Abstract

The invention discloses an automobile central channel drawing stamping die, a shaping die and a process surface modeling method. The drawing stamping die comprises an upper die seat, a lower die seat,a female die, an upper blank holder, a male die and a lower blank holder; the lower blank holder is located on two sides of the male die; a die profile of the male die is used for modeling a protruding main body part of an automobile central channel; a drawing parting line of the male die and the female die is located at the bottom of the side wall of the main body part; the lower blank holder isprovided with U-shaped grooves corresponding to grooves in the two sides of the automobile central channel; and the U-shaped grooves are used for forming prototype grooves of the grooves in the two sides of the automobile central channel in a drawing mode, and meanwhile the U-shaped grooves are used for forming drawing ribs of the die on a material pressing face. In design of a supplementary surface of a drawing process of the die, an additional supplementary surface in a traditional drawing process is omitted, so that the material utilization rate is improved, and the drawing difficulty of aproduct is reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a drawing stamping die and a shaping die for manufacturing the central passage of an automobile. The invention also relates to a molding method for the drawing and stamping process surface of the central channel of the automobile. Background technique [0002] With the continuous in-depth research and wide application of automobile lightweight, the reduction of vehicle weight directly leads to the optimization of the structure of stamping parts, which not only requires higher strength, but also requires lighter weight. [0003] The central channel of the car is located in the middle of the floor between the main driver and the co-pilot, and has high requirements for collision safety. If the absolute height difference of the parts reaches 170mm, it is very easy to have cracking defects during the drawing process, and it is usually very difficult to completely dra...
