Car body door cover plate edge rolling device and edge rolling method thereof

Abstract

The invention discloses a car body door cover plate edge rolling device which comprises a supporting table and a robot edge rolling seat, and further comprises a profile mechanism, wherein a rolling head is connected with the lower end of the robot edge rolling seat; the profile mechanism is connected with a telescopic mechanism; a molding bed is arranged on the supporting table; and a workpiece to be subject to edge rolling is arranged on the molding bed. The invention further discloses an edge rolling method of the car body door cover plate edge rolling device. According to the edge rollingmethod, a car body door cover plate to be subject to edge rolling is fit on the molding bed; a piston rod of an air cylinder is ejected, a push rod is driven to push out, and then a pre-bent profile is driven to advance; the car body door cover plate to be subject to edge rolling is pressed by the pre-bent profile is press, and the position, to be subjected to edge rolling, of the car body door cover plate to be subject to edge rolling is pressed by the forward side of the pre-bent profile; the rolling head on the robot edge rolling seat is driven by a robot arm to carry out primary edge rolling on the car body door cover plate to be subject to edge rolling; and the piston rod of the air cylinder is contracted, and the pre-bent profile is driven to retract. The car body door cover plate edge rolling device and the edge rolling method disclosed by the invention have the following advantages: the car body door cover plate can be protected against dislocation and deformation, the productquality can be guaranteed, the production efficiency can be improved, and the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to a rolling device and a rolling method for a door cover sheet of an automobile body. Background technique [0002] Due to the high cost of mold development and the insignificance of automated flexible production, more and more automobile manufacturers are using robot rolling operations instead of mold stamping operations for body door cover sheet parts. Die stamping adopts one-time forming, and robot roll edge adopts multi-channel forming process, generally more than 4, and the production efficiency is low. Moreover, in the current operation process of the roll hemming process, multiple operations are directly performed on the edge of the body door cover sheet. The body door cover sheet does not have any support during the flanging process, which may easily cause the body door cover sheet to be misaligned and deformed, resulting in Product quality varies. SUMMARY OF T...
