Problems solved by technology

[0002] The safety of the car is one of the most important indicators of the car. The energy absorption performance of the side collision of the car is far inferior to that of the front and rear collisions. The outer panels are all key parts to protect the passenger compartment. In related technologies, in order to enhance the strength of the A-pillar outer panels, B-pillar outer panels and door sill outer panels, reinforcement panels are added, but this will increase the weight of the vehicle body. Not conducive to the lightweight of the vehicle

Abstract

The invention discloses a side-frame outer plate manufacturing method. A side-frame outer plate comprises a column A outer plate, a column B outer plate and a threshold outer plate. The manufacturing method comprises the following steps of heating the part, corresponding to at least one of the column A outer plate, the column B outer plate and the threshold outer plate, in raw materials of the side-frame outer plate for the first scheduled time t1 till the temperature reaches the first preset temperature T1; and performing stamping and die assembly on the raw materials of the side-frame outer plate and cooling the heated part at the rate V till the temperature reaches the first preset temperature T2. The side-frame outer plate manufactured through the side-frame outer plate manufacturing method disclosed by the embodiment of the invention is high in strength, thus the side collision security of the vehicle is enhanced, and the lightweight level of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a method for manufacturing a side wall outer panel. Background technique [0002] The safety of the car is one of the most important indicators of the car. The energy absorption performance of the side collision of the car is far inferior to that of the front and rear collisions. The outer panels are all key parts to protect the passenger compartment. In related technologies, in order to enhance the strength of the A-pillar outer panels, B-pillar outer panels and door sill outer panels, reinforcement panels are added, but this will increase the weight of the vehicle body. It is not conducive to the lightweight of the whole vehicle. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. Therefore, an object of the present invention is to pro...
