Manual edge rolling device for automobile body-in-white stamping part

Abstract

The invention discloses a manual edge rolling device for an automobile body-in-white stamping part, which comprises a rack, a workpiece forming die arranged on the rack, at least one raceway trolley arranged on the workpiece forming die and edge rolling rollers correspondingly arranged on the raceway trolleys, and a supporting and positioning structure for stably positioning a workpiece is arranged on the rack. A raceway used for guiding the raceway trolleys is arranged on the workpiece forming die, trolley handles are arranged on the raceway trolleys, and the roller angle of the edge rolling rollers is consistent with the to-be-rolled edge angle of the workpiece. The edge rolling rollers are arranged on the raceway trolleys through self-locking mechanisms. The number of the raceway trolleys and the edge rolling rollers with different roller angles can be set according to the requirements of machining procedures, the structure is simple, operation is convenient, installation and adjustment are convenient, the raceway trolleys can be repeatedly used, time and labor are saved when the raceway trolleys run along a rail, the machining cost is reduced, and the manual edge rolling device for the automobile body-in-white stamping part is more suitable for flexible machining of multi-vehicle-type small-batch stamping parts.

Description

technical field [0001] The invention relates to a manual hemming device for stamping parts of automobile body-in-white, which belongs to the technical field of processing stamping parts of automobiles. Background technique [0002] The closure part of automobile body-in-white stamping parts is usually covered by the outer plate and the inner plate. After the inner plate is placed, the flanging or folding of the outer plate is hemmed. Rolling is one of the commonly used processing technologies for automobile body-in-white stamping parts. Now Some presses are used for edge wrapping. The upper mold of the press presses the lower mold, and the folding is pressed tightly by the clamping mold of the mold to realize the bending of the folding, so that the outer plate wraps the inner plate to achieve the purpose of assembly. This method Although the purpose of assembling the inner and outer panels can be achieved, the press is expensive and the input cost is high. [0003] There is...

[0002] The closure part of automobile body-in-white stamping parts is usually covered by the outer plate and the inner plate. After the inner plate is placed, the flanging or folding of the outer plate is hemmed. Rolling is one of the commonly used processing technologies for automobile body-in-white stamping parts. Now Some presses are used for edge wrapping. The upper mold of the press presses the lower mold, and the folding is pressed tightly by the clamping mold of the mold to realize the bending of the folding, so that the outer plate wraps the inner plate to achieve the purpose of assembly. This method Although the purpose of assembling the inner and outer panels can be achieved, the press is expensive and the input cost is high

[0003] There is also an existing method that uses a robot to carry a hemming tool for hemming, and the robot drives the roller to roll the hemming of the outer plate 141 of the stamping workpiece 14 and wrap the inner plate 142, which can also ensure a small working area and flexible manufacturing. Especially in the hemming of some small batches, but this kind of hemming adds an extra robot, and it takes a very long time to debug the robot linkage hemming. The cost is too high, resulting in high processing costs for stamping parts
