An automobile wheel cover hemming device

Abstract

The invention relates to an automobile wheel cover edge rolling device. The automobile wheel cover edge rolling device comprises a body (10), an upper pressing wheel set (1) and a lower pressing wheel set (2). The body (10) comprises a circular base and a mounting plate perpendicular to the base. The two surfaces of the mounting plate are provided with a wire gauge set (9) and a wire gauge set (11) respectively. The wire gauge set (9) is provided with a connecting block (7). The wire gauge set (11) is provided with a connecting block (12). The first connecting block (7) is provided with an air cylinder (17). The second connecting block (12) is provided with the lower pressing wheel set (2). A piston of the air cylinder (17) is connected with the second connecting block (12). The connecting block (7) is connected with a supporting block (6). The upper pressing wheel set (1) is mounted on the supporting block (6). The automobile wheel cover edge rolling device conducts edge rolling according to the shape of a plate and the shape of a tire mold; a roller head can automatically adjust the space according to the force balance principle so that the edge rolling force can keep uniform; the automobile wheel cover edge rolling device is simple in structure and good in edge rolling effect.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing assembly line, in particular to an automobile wheel cover hemming device. Background technique [0002] The basic structure of the existing car shell multi-roller hemming tool is 2 to 4 rollers, half of which are fixed rollers and the other half are position-variable rollers, so that the car shell is hemmed; but in practice Product defects often occur during use due to factors such as the material of the car shell and the thickness of the radius: such as uneven hemming force, ineffective control of hemming angle, inconsistent hemming, etc. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hemming device for automobile wheel covers. When hemming, according to the shape of the plate and the membrane, the rolling head group can automatically adjust the distance according to the principle of force balance, so that the hemm...
