Drawing forming die for rear section of lateral tail board of rear end of sports utility vehicle (SUV)

Abstract

The invention discloses a drawing forming die for the rear section of a lateral tail board of the rear end of a SUV. The drawing forming die comprises an upper die base, a lower die base, an upper die, a lower die and a blank holder and further comprises two upper blades and two lower blades. Cutting edge sides of the lower blades are in horizontal L shapes, and cutting edge sides of the upper blades are in shapes matched with the cutting edge sides of the lower blades. A blade groove matched with the lower blades is arranged at the positions close to two ends on the feeding side of the blank holder respectively, the ends of the blade grooves penetrate the ends of the blank holder, the two lower blades are mounted in the two blade grooves correspondingly, and cutting edges of the lower blades are disposed on the outside of the blank holder. The upper blades are mounted on the upper die, and positions of the upper blades are corresponding to the positions of the lower blades. Two material board support frames are further arranged on the feeding side of the blank holder and comprise support rods arranged horizontally, and the support rods are connected with one side of a blank holder frame, which is close to the feeding side of the blank holder, through vertical rods and connectors. By means of the drawing forming die, the drawing forming quality can be guaranteed, and the machining efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a drawing forming die for the rear section of the rear end side tailgate of an SUV. [0002] Background technique [0003] The rear section of the tailgate at the rear end of the car is a component on the D-pillar of the SUV car (the pillar between the glass behind the rear door and the rear door of the car), including the rear section of the left rear end side tailgate and the right rear end Rear section of side tailgate. The parts are usually made of metal plates (mainly stainless steel plates) through the following processing steps, namely: drawing forming, cutting, trimming, punching (upper and lower punching and side punching), shaping, etc.; drawing forming Finally, the final product is formed by repeating the above-mentioned trimming, punching and shaping until the rear section of the rear end side tail plate. Since the whole process is carried out through...

Problems solved by technology

However, in the actual processing process, because the sheet is rectangular, it is easy to cause damage to the sheet during the drawing process or to form wrinkles during forming, especially easy to cause cracks at one corner of the metal sheet, which affects the drawing and forming. Quality; the quality of drawing forming is poor, the yield is low, and its processing efficiency is also very low
